Uterus masculinus: an unusual complication in a case of feline urethral obstruction

A 6‐year‐old, male castrated domestic short hair cat presented for urethral obstruction. Despite passage of a urinary catheter, urine could not be drained through the catheter, but urine flow was noted around the catheter. Special imaging studies, including ultrasound and fluoroscopy, revealed that the catheter had been passed into an abnormal small bicornuate structure that entered the urethra from dorsally within the pelvic canal. This structure was believed to be a uterus masculinus or remnants of the Mullerian ducts. The anomalous structure was not felt to be related to the cause of the urethral obstruction, but was simply an incidental finding which resulted in difficult catheterization.

This paper describes a field trial designed to determine the value of bunamidine hydrochloride as an anthelmintic within the framework of the New Zealand hydatid eradication campaign and within an environment where there are no wild carnivorous animals host either to Echinococcus granulosus or to other Taeniidae with intermediate stages in sheep.     

Coccygeal epidural with local anesthetic for catheterization and pain management in the treatment of feline urethral obstruction

Objective – To describe the technique for performing a coccygeal epidural injection of local anesthetic to facilitate catheterization in male cats with urethral obstructions using low‐dose sedation. Significance – Prompt diagnosis and relief of urethral obstructions is important as many cats may have developed marked metabolic abnormalities at the time of presentation. General anesthesia in these patients may be associated with significant risk for complications. Pain management is also an essential treatment goal, and this technique relieves urethral and penile pain during the unblocking process. Conclusion – Coccygeal epidurals can be used safely to provide analgesia to the penis and urethra and to the authors' knowledge, is a novel treatment modality to aid in the relief of urethral obstructions in male cats.
