Intravesical formalin is a known treatment for control of hemorrhagic cystitis caused by multiple etiologies in humans and dogs. This case report documents the successful use of intravesical formalin for the treatment of severe hemorrhagic cystitis that occurred secondary to emphysematous cystitis in a diabetic dog. In addition, a review of emphysematous cystitis and the use of intravesical formalin in human and veterinary medicine is discussed. Formalin instillation into the urinary bladder is an option for life-threatening, refractory cases of hemorrhagic cystitis; but clinicians must be familiar with the proper technique and be aware of potential complications prior to its use. 相似文献

A 10-year-old, female West Highland white terrier was presented with poorly controlled diabetes mellitus and a previously undetected heart murmur. Emphysematous cystitis, emphysematous peritonitis and infective endocarditis of the tricuspid valve with gas accumulation were diagnosed with radiographs, including non-selective angiocardiography. The diagnoses were confirmed by post-mortem examination and positive cultures for Escherichia coli in blood, urine and tricuspid valve tissue samples. 相似文献

Polypoid cystitis is a rare disease of the urinary bladder in dogs characterized by chronic inflammation, epithelial proliferation, and development of a polypoid mass or masses without histopathologic evidence of neoplasia. The ultrasonographic appearances of eight dogs with polypoid cystitis are described. Ultrasonography confirmed the presence of a bladder mass or masses in all patients. Ultrasonographic findings are mucosal projections and a polypoid to pedunculated mass of variable size and shape. Although a polypoid mass tends to be located in the cranioventral bladder mucosa, the polyps also could arise in the craniodorsal bladder mucosa. Ultrasonographic images are well correlated with contrast radiographic studies and gross morphological appearance. Ultrasound is a non-invasive, very useful diagnostic tool for detecting bladder polyps, but histopathology is required for definitive diagnosis. 相似文献

Emphysematous cystitis is a rare disorder caused by bacterial infection and characterized by gas accumulation within the bladder wall with cyst formation. This report describes the histopathological characteristics of emphysematous cystitis found in a diabetic female beagle induced by streptozotocin and alloxan. Macroscopically, multiple cyst-like structures were observed on the cut surface of the urinary mucosa. During fixation, small specimens cut from the mucosa floated on the surface of the fixative solution. Histopathologically, multiple cysts were lined with a single layer of flattened cells found to be immunohistochemically positive for vimentin, partially positive for α-smooth muscle actin or macrophage scavenger receptor, class A, and thought to be myofibroblasts, fibroblasts or macrophages. Multinucleated giant cells were observed around the cysts, and gram-negative short bacilli were observed in the lumen of the urinary bladder. From these findings, this case was diagnosed as emphysematous cystitis. 相似文献

OBJECTIVE: To evaluate a method using Proteus mirabilis and Pseudomonas aeruginosa to experimentally induce dual infection of the urinary bladder in dogs. ANIMALS: 6 healthy mixed-breed dogs. PROCEDURE: Dogs were anesthetized, and cystitis was induced by infusing a solution of salicylic acid in ethanol into the bladder, followed by an inoculum containing field isolates of P. mirabilis and P. aeruginosa. Dogs were examined daily for 21 days after induction of cystitis. On day 21, dogs were euthanatized, and urinary bladder, renal pelvis, and prostate specimens were submitted for bacterial culture. RESULTS: After induction of cystitis, all dogs had evidence of thickening of the bladder wall, dysuria, tenesmus, and hematuria. Urinalysis revealed proteinuria, hematuria, and pyuria. All urine samples obtained on day 21 yielded growth of P. mirabilis, but P. aeruginosa was not cultured from any of these samples. Proteus mirabilis was isolated from bladder, renal pelvis, or prostate specimens from 4 dogs; P. aeruginosa was not isolated from any of the tissue specimens. CONCLUSION: Results suggest that the method used in the present study fails to induce dual infection of the urinary bladder with P. mirabilis and P. aeruginosa. The inability to establish a persistent dual infection with this method may have been a result of insufficient pathogenicity of the Pseudomonas isolate or an inadequacy of the experimental design. 相似文献

A 14-month-old, male German shepherd dog was evaluated for chronic, recurrent Escherichia coli urinary tract infection. An initial diagnosis of emphysematous cystitis was made, which resolved with appropriate antibacterial therapy. The urinary tract infection, however, did not resolve and on further investigation a bladder trigone diverticulum was evident, thought to be congenital in origin. This report describes the apparent ultrasonographic and radiological changes, and surgical repair of the diverticulum, and reviews the literature with regard to both congenital bladder trigone diverticulum and emphysematous cystitis. The former has never been documented in the dog and the latter is an unusual finding in a non-diabetic dog. 相似文献

Three dogs and one cat with lymphoma affecting the urinary bladder are reported and the findings on abdominal radiographs and ultrasound are described. Mural lesions representing lymphoma affecting the urinary bladder were identified ultrasonographically in all animals. The most common complications associated with urinary bladder lymphoma were hydronephrosis and hydroureter. In two patients contrast radiography was necessary to detect leakage of urine in the peritoneal and retroperitoneal space. The radiographic and ultrasonographic signs were similar to those reported with other urinary bladder neoplasms; hence urinary bladder lymphoma could not be distinguished from the more common urinary bladder neoplasms, such as transitional cell carcinoma. It is important to include lymphoma in the differential diagnosis of urinary bladder wall thickening and mural mass in dogs and cats. 相似文献

Polypoid cystitis is a rare disease of the urinary bladder in dogs characterized by inflammation, epithelial proliferation, and development of a polypoid mass or masses without histopathologic evidence of neoplasia. Medical records of 17 dogs with polypoid cystitis were reviewed to determine the clinical and laboratory features of this disorder and to assess treatment and outcome. Most affected dogs (15/17) were female and presented for evaluation of hematuria or recurrent urinary tract infection (UTI). Proteus spp were the most common bacterial isolates (12/52 or 23.1%) identified when all urine samples obtained for culture at any time during the course study were considered. Other commonly isolated organisms included Escherichia coli , Staphylococcus spp, and Enterococcus spp. Several dogs (7/17) also had cystic calculi at some time during the course of their disease. Most of the masses (11/14) were located cranioventrally in the bladder as opposed to transitional cell carcinoma, which has a predilection for the bladder neck or trigone area. It is unknown whether persistent or recurrent UTI predisposes to polyp formation or if polyps predispose to UTI. Surgery and removal of all polyps was the most efficacious treatment in dogs of this study. The question of whether or not polyps represent preneoplastic lesions remains unanswered and constitutes an area for future investigation. 相似文献

The objective of this study was to describe the clinical findings, medical management, and outcomes of horses with sabulous cystitis, and to describe a high flow bladder lavage procedure in horses that are standing or under general anesthesia. The medical records of 13 horses diagnosed with sabulous cystitis via cystoscopy between 2013 and 2020 were reviewed. Geldings (92%) and Warmbloods (46%) were overrepresented. The most common presenting complaint was urinary incontinence (69%). Complete blood cell count, serum biochemistry profile and urine cytology results were non-specific. Six (46%) horses had various degrees of erosion, ulceration, and hemorrhage of the bladder mucosa. All horses were treated with bladder lavage either with standing sedation (n = 12) or general anesthesia (n = 2), as well as antimicrobials (54%), anti-inflammatory drugs (62%), bethanechol (15%), and phenazopyridine (15%). Most horses (85%) were discharged from the hospital, but only a small percentage (23%) was reported as having no urinary abnormalities on follow-up communication.Key clinical message:Copious bladder lavage with a high flow rate system could mitigate the acute clinical signs and improve the quality of life of horses with sabulous cystitis, but the prognosis for return to previous level of athletic performance and long-term survival is guarded. 相似文献

Based on the findings of physical examination and on laboratory findings the urinary bladder of 23 cows was examined endoscopically in order to investigate the application of cystoscopy in cattle. The endoscopic findings of all examined cows were compared with the findings of physical examination and the results of macroscopic and microscopic urinalysis and the bacteriological culture of the urine. By physical examination only 3 cows were diagnosed to have urinary tract disease, whereas all other cows were suspected of having an urinary tract disease. Bacteriological culture of the urine revealed Corynebacterium renale and Escherichia coli infection in 18 cows, while the remaining 5 cows were negative. By cystoscopy catarrhal cystitis was diagnosed in 2 cases, haemorrhagic cystitis in 5 cases, and fibrinous-purulent and fibrinous-haemorrhagic cystitis in 13 cases. Three cows showed no pathological changes of the urinary bladder mucosa by endoscopic examination. Cystoscopy facilitates diagnosis through the direct visualisation of mucosal lesions and makes it possible to give a more accurate prognosis based upon the findings. 相似文献

Double-constrast and positive-contrast cystograms were performed in 12 dogs. After cystography, E. coli cystitis was induced in nine of the 12 dogs. The remaining three dogs were used as controls. Double contrast and positive-contrast cystograms were repeated threee, seven and 14 days later. During cystography, bladders were distended to mild, moderate, and complete degrees of distention. Mucosal irregularity decreased with increasing bladder distention and was more likely to be seen on double-contrast than on the positive-contrast cystogram. When seen on both types of studies, mucosal irregularity was more obvious on double-contrast than it was on the positive-contrast custogram. Bladder wall thickness decreased with increasing distention; in some dogs with mild cystitis, abnormal wall thickness was masked by complete bladder distention. Bladder wall thickness could be measured more often on double-contrast than on the positive contrast cystograms. Wall thickness measurments made on both types of studies were similar. It was concluded that lesions of mild to moderate cystitis may be missed when the bladder is completely distended, and that the double-contrast cystogram is more sensetive for evaluating mucosal margivation and bladder wall thickness than is the positive-contrast cystogram 相似文献

Results of a retrospective study of 22 dogs with signs of dysuria and/or stranguria in which a diagnosis of idiopathic detrusorurethral dyssynergia was made are presented. The diagnosis was based on the exclusion of detectable pathological conditions which could also cause urine outflow obstruction. The affected cases were 22 middle-aged male dogs (mean age 4·9 years) of large and giant breeds (mean bodyweight 36·7 kg). Nine dogs had had periodic clinical signs for longer than one year, one for seven months and eight for two to five weeks, while in four dogs signs had begun four to five days before referral. All dogs received the α-sympatholytic agent prazosin as an initial treatment and in 11 it remained the only therapy. There was a good effect in seven and a moderate response in the other four dogs. In one dog, prazosin was ineffective and was replaced by diazepam, which markedly reduced the signs. Three other dogs required frequent catheterisation and antibiotics were administered. These dogs responded favourably. Another three dogs with evidence of impaired bladder contractility were also treated with the parasympathomimetic agent carbachol. One did not improve and was euthanased. Four dogs developed bladder paralysis and severe infectious cystitis. Only one of these could be managed satisfactorily by long-term administration of prazosin, carbachol and antibiotics, and the others had to be euthanased. 相似文献

An 18-year-old male neutered domestic shorthair cat was presented for investigation of haematuria and lethargy. The cat had sustained a traumatic T3-L3 lesion 5 years prior resulting in upper motor neuron incontinence. On further investigation the cat was found to be hyperkalaemic, hypothermic and dehydrated. Ultrasonography of the bladder revealed a markedly hypoechoic, thickened bladder wall with an irregular, hyperechoic mucosal layer. The patient responded to symptomatic and supportive care and was discharged. Despite initial improvement, the patient returned 10 days after discharge with recurrence of haematuria and lethargy. Ultrasound-guided aspiration and culture of the material on the mucosal surface of the bladder confirmed diagnosis of UTI caused by Corynebacterium urealyticum. On post-mortem examination, gross and histopathological features were consistent with encrusting cystitis. This is the first case report of encrusting cystitis in a cat. C urealyticum, an uncommon urinary tract pathogen in small animals, should be considered in patients with predisposing conditions. 相似文献

This report compares results from imaging of transitional cell carcinoma of the urinary bladder in 15 dogs using intravenous urography, double-contrast cystography, and ultrasonography. Intravenous urography demonstrated filling defects in the urinary bladder in 3 of the 5 cases examined with this modality. Double-contrast cystography identified bladder masses in 8 of 10 animals. Ultrasonography was the only imaging modality which detected bladder masses in all patients. 相似文献

OBJECTIVE: To identify clinical features of Corynebacterium urealyticum urinary tract infection in dogs and cats and antimicrobial susceptibility patterns of C urealyticum isolates. DESIGN: Retrospective study. ANIMALS: 5 dogs and 2 cats. PROCEDURE: Medical records of dogs and cats for which C urealyticum was isolated from urine samples were reviewed. Isolates from clinical cases, along with previously lyophilized unsubtyped isolates of Corynebacterium spp collected between 1977 and 1995, were examined and, if subtyped as C urealyticum, tested for antimicrobial susceptibility. RESULTS: Signalment of infected animals was variable. Prior micturition disorders were common, and all animals had signs of lower urinary tract disease at the time C urealyticum infection was diagnosed. Median urine pH was 8.0; WBCs and bacteria were variably seen in urine sediment. In vitro antimicrobial susceptibility testing of 14 C urealyticum isolates revealed that all were susceptible or had intermediate susceptibility to chloramphenicol, tetracycline, and vancomycin and most were susceptible to enrofloxacin. Thickening of the bladder wall and accumulation of sediment were common ultrasonographic findings. Contrast radiography or cystoscopy revealed findings consistent with encrusting cystitis in 3 dogs. Infection resolved in 2 dogs following surgical debridement of bladder plaques and antimicrobial administration. In 2 other dogs and 1 cat treated with antimicrobials, infection with C urealyticum resolved, but urinary tract infection with a different bacterial species developed. CONCLUSIONS AND CLINICAL RELEVANCE: Results suggest that preexisting urinary tract disorders are common in dogs and cats with C urealyticum infection. Treatment with appropriate antimicrobials in combination with surgical debridement might eliminate C urealyticum infection. 相似文献

A 4.5-month-old Standard-bred filly was referred for evaluation of pigmenturia. Initially, the pigmenturia had resolved with the administration of antibiotics, only to recur after their withdrawal. A dark red urine sample contained numerous RBC, WBC, and gram-negative rods (Escherichia coli). Ultrasonography revealed the right kidney to be large, with multiple cystic structures and a dilated renal pelvis and calices. Cystoscopy revealed a large blood clot within the bladder and urine coming from the left ureteral opening. Urine was not observed coming from the right ureter. It was suspected that the primary infection within the urinary tract was coming from the right kidney, with secondary ureteral obstruction and cystitis. Trimethoprim-sulfamethoxazole treatment was initiated. However, acute depression and abdominal pain developed several days later, and the foal died before assistance could be provided. Necropsy revealed a large abscess that had eroded into the right ureter and aorta and had ruptured, resulting in acute blood loss and death. The location and extensive nature of the lesion would have precluded surgical intervention. 相似文献

The mucosal margin of the urethra is best assessed by positive contrast urethrography, but ultrasonography offers complementary information such as urethral wall thickness and size of medial iliac lymph nodes. Ultrasonography of the urethra is quick, noninvasive and does not require sedation or general anesthesia. In patients with complete urethral obstruction, ultrasonography may be the only way to image the urethra. Twelve dogs which were presented to Tufts University School of Veterinary Medicine with clinical signs referable to the urinary bladder, urethra or vagina were examined ultrasonographically. Seven were neutered females and five were neutered males. Each dog had a hyperechoic, nonshadowing line at the epithelial surface of the proximal urethra. In the seven female patients and one of the males, the urethral wall was also thick and hypoechoic to surrounding tissue. In the other males, the urethral epithelial changes were at the level of the prostate, and the limits of the urethra were not visible. In six dogs, the urethral change was the only abnormality seen, while in six, bladder wall, bladder luminal and/or prostatic parenchymal changes were also detected. Three patients had hydronephrosis, and one had enlarged medial iliac lyumph nodes. Biopsies were obtained via suction with urinary catheterization (n = 6), exploratory celiotomy (n = 3), urethroscopy (n = 2), or at post-mortem (n = 1). A histopathologic diagnosis of urethral transitional cell carcinoma was obtained in ten dogs. The ultrasonographic appearance was not pathognomonic for transitional cell carcinoma, as one dog with transitional cell dysplasia and one dog with severe ulcerative and necrosupperative cystitis and urethral stricture had similar findings. 相似文献

Survey abdominal radiographs, excretory urograms, and nephrosonograms were obtained from 14 dogs with renal lesions. Renal enlargement was suspected on survey radiographs and confirmed by excretory urography in 13 dogs. Radiographic differentiation between a solid and cystic renal lesion was not possible in 9 dogs. Ultrasonography determined the presence of solid masses in 12 dogs, established the presence of a renal cyst in the opposite kidney in 1 dog, and revealed hydronephrosis in 2 dogs. Ultrasonography appeared to be more sensitive than radiography in differentiating the internal characteristics of renal lesions. 相似文献

The aim of this study was to demonstrate and assess C-reactive protein (CRP) changes in dogs with induced bacterial cystitis with or without antibiotics. We also evaluated availability of CRP levels to serve as an indicator for monitoring or diagnosing bacterial cystitis. Serial CRP concentrations in dogs with induced bacterial cystitis were higher than those of controls (p < 0.001). CRP concentrations peaked on day 7 and gradually decreased thereafter. In the treatment group, CRP concentrations decreased after medication compared to the untreated group (p = 0.032). CRP levels had a linear correlation with urine white blood cell counts among all groups (r = 0.837, p < 0.001, n = 140). Compared to the negative urine culture group, dogs with positive urine culture results had higher CRP concentrations (median 43.8 mg/L vs. 5.9 mg/L; p < 0.001). Area under the receiver operating characteristic curve was 0.955; when cut-off value was 12.2 mg/L, CRP measurements were found to have a sensitivity of 92.3% and specificity of 86.4%. This result indicates that rapid increases of CRP occurred after inducing bacterial cystitis and CRP may be a useful indicator for monitoring or diagnosing canine bacterial cystitis together with sediment urinalysis and urine bacterial culture. 相似文献
