Vaginal resection and anastomosis for treatment of vestibulovaginal stenosis in 4 dogs with recurrent urinary tract infections

CASE DESCRIPTION-4 dogs were evaluated because of recurrent urinary tract infections. CLINICAL FINDINGS-All dogs had recurrent urinary tract infections and similar clinical signs; 3 dogs had urinary incontinence. Digital vaginal examination revealed vestibulovaginal stenosis in all dogs, which was confirmed by results of contrast vaginourethrography. From image measurements, the vestibulovaginal ratio (ratio of the height of the vestibulovaginal junction to the maximum height of the vagina on a lateral vaginourethrogram) was calculated for each dog. Three dogs had severe stenosis (vestibulovaginal ratio, < 0.20; severe stenosis is defined as a vestibulovaginal ratio < 0.20), whereas the fourth dog had moderate stenosis (vestibulovaginal ratio, 0.24; ratio range for moderate stenosis is 0.20 to 0.25). TREATMENT AND OUTCOME-All dogs were anesthetized for surgical correction of the vestibulovaginal stenosis. Vaginal resection and anastomosis of the stenosis was performed in all 4 dogs, with 1 dog also undergoing episioplasty. Complete resolution of clinical signs was apparent in 3 dogs; 1 dog had postoperative complications including pollakiuria and stranguria, which resulted in rectal and vaginal prolapse. This dog underwent ovariohysterectomy, after which clinical signs resolved. All dogs had resolution of urinary tract infections at the time of follow-up (6 to 8 months after surgery). CLINICAL RELEVANCE-Resection and anastomosis may resolve recurrent urinary tract infections in dogs with severe or moderate vestibulovaginal stenosis. Episiotomy was not necessary for success of surgical treatment, and overall, that procedure increased morbidity, the severity of intraoperative hemorrhage, and duration of surgery.     

Vestibular, vaginal, and urethral relations in spayed dogs with and without lower urinary tract signs

The purpose of this study was to evaluate the urogenital anatomy in female spayed dogs with and without signs of lower urinary tract disease by using conventional vaginourethrography, computed tomography (CT) vaginourethrography, and uroendoscopy. Nineteen dogs with lower urinary tract disease and 12 normal dogs were evaluated prospectively. Measurements made included vaginal length, vaginal height, vaginal width, vestibule length, vestibule height, vestibule width, vestibulovaginal ratios, cingulum height, cingulum width, cingulum area, urethral length, urethral height, urethral width, angle of urethra to vestibule, and angle of vaginal to vestibule. Group comparisons were made between dogs with and without lower urinary tract disease. Comparisons between conventional vaginourethrography and CT vaginourethrography were made when the same anatomical measurement was made by the 2 imaging modalities. There was no significant difference in all of the measurements (P > .01), including vestibulovaginal ratios and cingulum areas, between dogs with and without lower urinary tract disease. There was a larger proportion of dogs with a vestibulovaginal ratio <0.33 in normal dogs (8 of 12) compared with the clinical dogs (8 of 16). A significant difference between vestibulovaginal ratios or cingulum areas between dogs with and without lower urinary tract disease could not be identified. This suggests that a vestibulovaginal ratio of <0.33 may only be an incidental finding and the term "vestibulovaginal stenosis" may need to be redefined.     

Results of vulvoplasty for treatment of recessed vulva in dogs.

The results of vulvoplasty were evaluated in 34 dogs that underwent surgery at the University of Wisconsin Veterinary Medical Teaching Hospital between 1987 and 1999. Case records were evaluated, and clients were interviewed by telephone. The most common clinical signs of a juvenile or recessed vulva at initial examination were perivulvar dermatitis in 59% (20/34) of dogs and urinary incontinence and chronic urinary tract infection (UTI), each present in 56% (19/34) of dogs. Other common complaints included pollakiuria, irritation, and vaginitis. Most dogs developed clinical signs before 1 year of age. All dogs except one bichon frise were medium to giant breeds, suggesting that vulvar conformation may be related to growth rate or body conformation; prior ovariohysterectomy did not appear to be an influencing factor. Eighty-two percent of owners rated the outcome of the surgery as at least satisfactory. The incidence of urinary incontinence was reduced by vulvoplasty; however, it remained the most common residual sign after surgery, suggesting a multifactorial etiology. The incidences of UTI, vaginitis, and external irritation were greatly reduced after surgery.     

Imaging findings and surgical treatment of hemivertebrae in three dogs

CASE DESCRIPTION: 3 immature screw-tailed dogs were evaluated because of progressive pelvic limb paraparesis. CLINICAL FINDINGS: Each dog had marked ataxia and paresis of the pelvic limbs and a palpable deformity of the midthoracic portion of the vertebral column. Pain perception in the pelvic limbs was considered normal, and there was no evidence of fecal or urinary incontinence in any of the 3 dogs. Radiography and magnetic resonance imaging revealed hemivertebrae with severe dorsoventral stenosis of the vertebral canal resulting in spinal cord compression in 2 dogs and lateral compression in the other. TREATMENT AND OUTCOME: Each dog underwent decompressive surgery consisting of dorsal laminectomy or hemilaminectomy and vertebral stabilization by use of combinations of Kirschner wires or threaded external fixator pins plus polymethylmethacrylate bone cement. All dogs regained strong locomotor function with minimal residual pelvic limb ataxia. CLINICAL RELEVANCE: Little detailed information regarding surgical treatment of hemivertebrae in dogs is available; results of treatment in these 3 dogs suggest that spinal cord decompression and stabilization of the vertebral column can achieve a satisfactory, functional outcome.     

Importance of urethral length, bladder neck position and vestibulovaginal stenosis in sphincter mechanism incompetence in the incontinent bitch

The urethral length, bladder neck position and presence of vestibulovaginal stenosis were recorded in 42 continent bitches and 57 incontinent bitches diagnosed as having sphincter mechanism incompetence. Incontinent animals had significantly shorter urethras and tended to have intrapelvic rather than intraabdominal bladder necks. There was no statistical difference in the incidence of vestibulovaginal stenosis between continent and incontinent bitches.     

Prevalence and radiologic and histologic appearance of vesicourachal diverticula in dogs without clinical signs of urinary tract disease

OBJECTIVE: To determine prevalence and radiologic and histologic appearance of vesicourachal diverticula in dogs without clinical signs of urinary tract disease. DESIGN: Original study. ANIMALS: 50 dogs between 4 months and 17 years old representing 22 breeds that had been euthanatized for unrelated reasons; none of the dogs had a history or clinical signs of urinary tract disease. PROCEDURE: Retrograde positive-contrast radiography was performed, and radiographs were examined for macroscopic diverticula. Necropsy specimens from the urinary bladder vertex were examined by means of light microscopy for diverticula and signs of inflammation. RESULTS: 17 of the 50 (34%) dogs had vesicourachal diverticula, and 1 additional dog had a urachal cyst. Fifteen of the 17 diverticula were macroscopic; surface area of the diverticulum could be measured radiographically in 13 of these dogs and ranged from 1 to 90 mm2. The remaining 2 diverticula were microscopic. Sixteen diverticula were intramural and 1 was extramural. Light microscopic signs of bladder wall inflammation could be detected in 5 dogs, 4 of which had macroscopic diverticula. CONCLUSIONS AND CLINICAL RELEVANCE: Results suggest that a high percentage of dogs without clinical signs of urinary tract disease may have vesicourachal [corrected] diverticula. Further studies are needed to determine the clinical relevance of vesicourethral diverticula in dogs.     

Prepubic urethrostomy: A long-term study in 16 cats

OBJECTIVE: To investigate the indications for and long-term outcome of prepubic urethrostomy (PPU) in the cat. STUDY DESIGN: Retrospective survey. ANIMALS: Sixteen cats that had undergone PPU. METHODS: Data were recovered from the medical records of the cats. Follow-up information was obtained from the owners and referring veterinarians. RESULTS: Indications for PPU were: failed perineal urethrostomy for the management of idiopathic lower urinary tract disease (ILUTD) (8 cats) or urethral trauma (1 cat); unresolved pelvic urethral obstruction after recurrent ILUTD (5 cats); and stenosis of the pelvic urethra as a result of trauma (2 cats). A patent urethral stoma was created in all cases. Signs of lower urinary tract disease were present in 8 cats postoperatively. With appropriate dietary management, these signs resolved in 2 cats and improved in another 4 cats. Eleven cats experienced postoperative complications that consisted of peristomal skin irritation or necrosis (7 cats) and urinary incontinence (6 cats). Complications developed in the immediate postoperative period in 6 cats, and resolved in 2 of these. Six cats developed late complications, at 6 to 84 months postoperatively. Six cats were euthanatized between 1 and 26 months' postoperatively. The mean survival time in these cats was 13 months. Reasons for euthanasia included urinary incontinence (3 cats), skin necrosis (2 cats), and unresolvable ILUTD (1 cat). CONCLUSIONS: PPU is a salvage procedure that is successful in relieving the signs of urinary tract obstruction and preventing further obstruction. However, potential complications should limit its use to cases in which standard techniques for perineal urethrostomy cannot be performed. CLINICAL RELEVANCE: PPU is a comparatively simple procedure that should be considered as a salvage technique for obstructive disease of the pelvic urethra.     

A technique for resection of invasive tumors involving the trigone area of the bladder in dogs: preliminary results in two dogs

Objective— To describe a surgical technique for resection of the entire bladder neck, including the trigone and proximal urethra in dogs with invasive tumors causing life-threatening urinary tract obstruction.
Study Design— Clinical case reports.
Animals— Dogs (n=2) with bladder tumors.
Methods— Circumferential excision of the bladder neck and proximal urethra with preservation of the neurovascular pedicles was performed to remove a rhabdomyosarcoma (dog 1) and a transitional cell carcinoma (dog 2) involving the trigone and bladder neck that were causing urinary tract obstruction. Reconstruction of the bladder and proximal urethra included bilateral ureteroneocystostomy. Adjuvant chemotherapy was administered postoperatively to both dogs.
Results— Postoperatively, dogs 1 and 2 were continent after 7 and 17 days, respectively, and regained normal urinary function after resolution of a transient pollakiuria. Dog 1 had no evidence of local or regional recurrence; however, a large solitary pulmonary metastatic lesion was diagnosed 8 months later. The dog was euthanatized despite a lack of clinical signs. Dog 2 had at least 1 metastatic lesion in the abdominal wall 6 months later and was euthanatized at 580 days because of renal failure.
Conclusion— En-bloc removal of the bladder neck and proximal urethra with preservation of the dorsal vascular and nervous pedicles, although a technically challenging procedure, can be performed without associated urinary incontinence or bladder wall necrosis.
Clinical Relevance— In dogs with invasive bladder tumors causing life-threatening urinary tract obstruction, resection of the bladder neck and proximal urethra should be considered as a promising surgical alternative to urinary diversion.     

Predictors of outcome after dorsal decompressive laminectomy for degenerative lumbosacral stenosis in dogs: 69 cases (1987-1997)

OBJECTIVE: To identify predictive factors of long-term outcome after dorsal decompressive laminectomy for the treatment of degenerative lumbosacral stenosis (DLSS) in dogs. DESIGN: Retrospective study. SAMPLE POPULATION: 69 client-owned dogs. PROCEDURE: Medical records of dogs that had undergone dorsal laminectomy at North Carolina State University and the University of Tennessee between 1987 and 1997 were reviewed. Dogs with diskospondylitis, traumatic lesions, or neoplasia of the lumbosacral region were excluded. All dogs had evidence of cauda equina compression on myelography, epidurography, computed tomography, or magnetic resonance imaging, along with subsequent confirmation of the lesion at surgery. Follow-up was performed by telephone inquiries to the referring veterinarian, the owner, or both, using a detailed questionnaire. RESULTS: The outcome was excellent or good in 54 of 69 (78%) dogs over a mean follow-up period of 38+/-22 months. Five of these 54 dogs had been incontinent for a median of 2 weeks prior to surgery. Six of the 15 dogs with a poor outcome had been incontinent for a median of 8 weeks before surgery. A significant correlation was detected between the presence of urinary and fecal incontinence prior to surgery and outcome. When duration of signs was considered, urinary incontinence was the only variable that significantly affected outcome. CONCLUSIONS AND CLINICAL RELEVANCE: Decompressive laminectomy is an effective treatment for DLSS, although dogs with urinary or fecal incontinence have a worse prognosis than dogs that are continent before surgery. Chronic urinary incontinence is a predictor of poor outcome for dogs with DLSS.     

Treatment of cyclophosphamide-induced hemorrhagic cystitis in five dogs

Sterile hemorrhagic cystitis developed in 5 dogs after treatment with cyclophosphamide. Four dogs were being treated with various antineoplastic protocols, and the fifth dog had recurrent immune-mediated thrombocytopenia. In all instances, clinical signs of hematuria and stranguria persisted after cyclophosphamide administration was discontinued. Three dogs required cystotomy to remove necrotic mucosa and calculi. The other 2 dogs were treated with intravesicularly administered dimethyl sulfoxide to decrease inflammation and to inhibit fibroplasia of the bladder wall. In 4 dogs, clinical signs resolved after treatment. The fifth dog, treated surgically, continued to have intermittent urinary incontinence attributable to residual bladder wall fibrosis.     

POSITIVE CONTRAST RETROGRADE URETHROGRAPHY: A USEFUL PROCEDURE FOR EVALUATING URETHRAL DISORDERS IN THE DOG

Positive contrast retrograde urethrography proved to be a useful and relatively simple technic for the evaluation of lower urinary tract disorders in the dog. The case histories of 12 dogs with such disorders were used to illustrate the role of positive contrast retrograde urethrography in the evaluation of urethral and urinary bladder integrity after caudal abdominal and pelvic trauma, and in the investigation of incontinence, stranguria, dysuria, and hematuria.     

High Urine Concentrations of Basic Fibroblast Growth Factor in Dogs With Bladder Cancer

Because dogs with bladder cancer often have advanced disease at the time of diagnosis, the identification and use of a tumor marker that could facilitate earlier diagnosis is a valid approach to improve prognosis. The objective of this study was to determine if urine concentrations of the proan-giogenic peptide, basic fibroblast growth factor (bFGF), are high in dogs with bladder cancer compared with normal dogs and dogs with urinary tract infection. We used a commercially available enzyme-linked immunosorbent assay test kit to quantitate bFGF in the urine of 17 normal dogs, 10 dogs with urinary tract infection, and 7 dogs with locally active transitional cell carcinoma of the urinary bladder. In normal dogs, the median urine bFGF concentration was 2.23 ng/g creatinine (quartile range, 1.53 to 5.12 ng/g creatinine). The median urine bFGF concentration in dogs with urinary tract infection did not differ significantly from normal dogs. Dogs with bladder cancer had significantly higher urine bFGF concentrations than normal dogs ( P < .002) and dogs with infection ( P < .02). The median urine bFGF concentration in dogs with transitional cell carcinoma was 9.86 ng/g creatinine (quartile range, 7.40 to 21.63 ng/g creatinine). Six of 7 dogs with bladder cancer had urine bFGF concentrations that were up to 7.4 times the 90th percentile value for normal dogs. Only 1 of 10 dogs with infection had a urine bFGF concentration that exceeded the 90th percentile of normal. These data suggest that canine bladder cancers export bFGF, and that urine bFGF may be useful as a diagnostic tumor marker or noninvasive indicator of treatment response.

Canine Bladder and Urethral Tumors: A Retrospective Study of 115 Cases (1980–1985)

One hundred and fifteen dogs with neoplasms of the lower urinary tract (bladder and/or urethra) were retrospectively evaluated at five referral institutions participating in ongoing studies by the Veterinary Cooperative Oncology Group. Most tumors were malignant (97%) and of epithelial origin (97%). Lower urinary tract tumors were more common in older dogs weighing greater than 10 kg. The following significant (P less than 0.05) statistical associations were found using the University of Guelph hospital population as control; there was no sex predisposition although the female:male ratio was 1.95:1. Neutered dogs were predisposed as were Airedale Terriers, Beagles, and Scottish Terriers, whereas German Shepherds were significantly under-represented among dogs with lower urinary tract tumors. These statistical associations should be interpreted cautiously because of possible demographic differences in hospital populations among the University of Guelph and other cooperating institutions. There were no significant correlations between age, gender, weight, breed, response to therapy, and survival time. Clinical signs were indicative of lower urinary tract disease and included hematuria, stranguria, and pollakiuria. The laboratory data were nonspecific except for urinalysis test results. Hematuria and inflammatory urinary sediments were most commonly reported; neoplastic cells were identified in the urine sediment of 30% of dogs with lower urinary tract tumors. Contrast cystography was a useful noninvasive diagnostic method since 96% of the dogs had a mass or filling defect in the lower urinary tract demonstrated by this technique.(ABSTRACT TRUNCATED AT 250 WORDS)     

Congenital Ureteral Ectopia in Continent and Incontinent‐Related Entlebucher Mountain Dogs: 13 Cases (2006–2009)

Background: Ectopic ureters (EUs) associated with varying combinations of urinary incontinence, hydronephrosis, and urinary tract infection have been identified in related North American Entlebucher Mountain Dogs. Objectives: To characterize the disease phenotype in affected dogs and evaluate possible modes of inheritance. Animals: Twenty client‐owned Entlebucher Mountain Dogs. Nine dogs had clinical signs of urinary tract disease. Methods: Prospective case series in which 17 dogs were evaluated with excretory urography, ultrasonography, and urethrocystoscopy. Three additional dogs were evaluated by necropsy alone. Clinical and pedigree histories from 165 North American Entlebuchers were compiled for analysis. Results: Eleven female and 2 male dogs were found to have EUs. Six females and 1 male were continent. Bilateral intravesicular ectopic ureters (IVEUs) were identified in 9 dogs, bilateral extravesicular ectopic ureters (EVEUs) in 3 dogs, and 1 dog had IVEU and EVEU. Hydronephrosis was identified in 5 dogs, 3 of which had bilateral IVEUs. Two necropsied dogs had bilateral hydronephrosis with presumed ureterovesical junction obstruction associated with chronic granulation tissue or lymphoplasmacytic inflammation. Twenty‐six dogs with EUs were identified in the pedigree. Because of incomplete penetrance, mode of inheritance could not be determined. Conclusions and Clinical Importance: Ureteral ectopia is common in North American Entlebucher Mountain Dogs and clinical signs alone could not reliably predict disease phenotype. EVEUs were associated with urinary incontinence and occasionally hydronephrosis. IVEUs were clinically silent or associated with hydronephrosis. Further analyses are necessary to confirm and characterize the hereditary nature of the disorder.     

Clinical and Surgical Parameters in Dogs with Perineal Hernia Analysis of Results of Internal Obturator Transposition

The results of treatment of 31 dogs with perineal hernia by internal obturator muscle transposition were evaluated by comparing the clinical signs reported by the owner before surgery with those reported 11 or more months following surgery. The severity and frequency of pre- and postoperative clinical signs were categorized numerically, and composite scores were obtained for each dog. In addition, the dogs were examined 11 or more months following surgery. The presence or absence of an externally obvious perineal swelling was noted, and rectal examination was performed to detect rectal sacculation and the integrity of the pelvic diaphragm dorsal and ventral to a line drawn between the center of the anus and the ischiatic tuberosity. These results were correlated with the postoperative composite scores. Postoperative complications included wound infection (2), wound seroma (2), rectal prolapse (4), urinary incontinence (2), and flatus as a new postoperative problem (11). The postoperative composite score was significantly lower (improved function) following surgery. Dogs with worse signs preoperatively or bilateral perineal hernia benefited less from surgery. More dogs showed improvement when the operation was performed by experienced surgeons. Factors detected at follow-up examination that correlated with more severe postoperative clinical signs were perineal swelling, absence of the ventral portion of the pelvic diaphragm, and rectal sacculation. The presence or absence of reformation of the dorsal aspect of the pelvic diaphragm did not correlate with postoperative clinical signs.     

Relationship of upper and lower urinary tract infection and bacterial invasion of uroepithelium to antibody-coated bacteria test results in female dogs

Urinary tract infection was demonstrated in 12 female dogs via bacteriologic culture of a specimen of bladder urine collected by antepubic cystocentesis. Escherichia coli was isolated in pure culture from the urine of 9 dogs. Urine specimens from 2 dogs contained E coli and alpha-streptococci and from 1 dog contained Streptococcus zymogenes in pure culture. In 6 dogs, urinary tract infection was limited to the urinary bladder, whereas 6 dogs had unilateral or bilateral culture-positive renal pelvic urine as well (specimens collected by percutaneous nephropyelostomy). An antibody-coated bacteria (ACB) test was conducted on a portion of the bladder urine specimen from each dog, and the urinary tissues from these 12 dogs and from 6 healthy, noninfected female dogs were examined at necropsy. Tissues were given a subjective score based on the severity of the lesions seen microscopically. Histologic scores, bacterial cultural results, and ACB test results were examined for significance. A significant difference was found in the histologic scores between infected and noninfected dogs (P less than 0.025), but comparisons among histologic scores, cultural results, and ACB test results were not significant among infected dogs. The ACB test could neither be used to localize bacterial infection within the urinary tract nor could it be used to indicate the presence of bacterial invasion of the uroepithelium in dogs.     

Urinary tract infection: The role of canine transmissible venereal tumour

The role of transmissible venereal tumours in the pathogenesis of urinary tract infection in dogs was investigated in 86 dogs. Fifty-five had transmissible venereal tumours, and the remaining 31 animals were used as controls. A thorough clinical examination of the external genitalia was carried out in each case. In the dogs with transmissible venereal tumours, the sites of attachment were recorded. Urine samples were taken by cystocentesis and the external genitalia swabbed; the samples were cultured for bacteria using standard methods. Tumours were found on the prepuce and other parts of the penis in male dogs; in bitches they were found in the vagina, vestibule or the vestibulovaginal junction. Dogs with transmissible venereal tumours were found to be at a high risk of having bacteriuria (odds ratio [OR] = 7.04). Obliteration of the urethral orifice by the tumour, possibly leading to urine retention, was thought to be the main reason for the high incidence of urinary tract infection among dogs with transmissible venereal tumours. Long-standing cases of transmissible venereal neoplasia had a higher chance of becoming bac-teriuric compared with recent cases (OR=29–60). This study indicates that transmissible venereal tumour may be a predisposing factor for the development of urinary tract infection.     

Cystourethropexy to Correct Refractory Urinary Incontinence Due to Urethral Sphincter Mechanism Incompetence Preliminary Results in Ten Bitches

Cystourethropexy was performed in 10 bitches with refractory urinary incontinence due to urethral sphincter mechanism incompetence. All animals had an abnormally shaped vesico-urethral junction. The bladder neck was located in the pelvic canal in nine dogs (pelvic bladder). Surgery alone restored urinary continence in two cases and markedly improved incontinence in two cases. Surgery combined with medical therapy (phenylpropanolamine, 1.5 mg/kg orally once or twice a day, using a sustained-action preparation) restored urinary continence in four cases and markedly improved continence in one case. Surgery, with medical therapy, was completely ineffective in one case. No major complications were encountered in any dogs. In four cases, histopathologic evaluation of the dorsal bladder wall and neck revealed the presence of a single, perinuclear, clear vacuole in the cytoplasm of smooth muscle fibers. Electron microscopic examination showed that the vacuoles represented a dilatation of normal membrane organelles. Such abnormalities have the potential to alter the smooth muscle motility. This study indicates that cystourethropexy alone restored urinary continence only temporarily in the majority of the patients. The significance and frequency of the histopathologic findings requires further investigation.     

Urologic disorders of the geriatric dog

Disorders of the urinary system are common in geriatric dogs. Common urinary disorders that are seen in older dogs include chronic renal failure, urinary incontinence, bladder tumors, and prostate problems. Therapy for chronic renal failure is aimed at both slowing the progression of the disease and ameliorating the signs of uremia. Therapeutic recommendations for the conservative medical management of chronic renal failure include reducing dietary protein, moderately reducing salt intake, maintaining normal serum phosphorus levels, providing free access to water, avoiding stress, supplementing water soluble vitamins, using anabolic steroids to treat the anemia of chronic renal failure, treating acidosis, and controlling hypocalcemia. Urinary incontinence can often be controlled or eliminated. The appropriate approach to management of this disorder is to identify and remove specific causes. Common causes of urinary incontinence are urethral incompetence, urinary tract infection, and polyuria and polydypsia. Bladder tumors are, fortunately, not a common tumor of dogs, but are more common in geriatric dogs than in the young. The most common bladder tumor is the transitional cell carcinoma. Therapy for this tumor is usually palliative because of its malignant nature and because it is usually located in the neck of the bladder. Its location in the bladder often makes it impossible to resect the tumor completely without removing the entire bladder and diverting the ureters. New chemotherapeutic modalities are being evaluated that may increase life expectancy after diagnosis and, therefore, improve prognosis. Prostate disease is also seen in older dogs. Types of prostate abnormalities seen in dogs include prostatic hyperplasia, cysts, abscesses, acute and chronic infection, and neoplasia. The institution of proper therapy requires an accurate diagnosis; neutering is often recommended as a part of therapy regardless of the type of prostatic disease present.     

Diagnosis and management of ureteroceles in two female dogs

Two intact female dogs were examined for refractory pollakiuria and stranguria. One of these two dogs also exhibited urinary incontinence. Ectopic ureteroceles were diagnosed via ultrasonography and cystoscopy in both dogs. Both dogs were taken to surgery for ureterocele resection and neoureterostomy, resulting in complete resolution of clinical signs. Although uncommonly reported in the veterinary literature, ectopic ureteroceles can be associated with recurrent lower urinary tract infection with and without urinary incontinence. With a correct diagnosis and appropriate treatment, prognosis for ectopic ureteroceles can be good provided there is not a concurrent significant loss of renal function.
