Complications associated with perineal urethrotomy in 27 equids.

This research is a retrospective study that investigates the clinical outcomes and complication rates of perineal urethrotomy, a surgical treament for urinary tract disorders, in horses during a decade-long period. The study makes significant findings, including the effectiveness of post-operative cystoscopy and bladder lavage in reducing recurrence of urinary stones.

Research Methodology

• The study uses a retrospective approach, where the researchers examined medical records from January 2000 to December 2010.
• The research encompasses 27 equids (horse family animals) that had undergone perineal urethrotomy during the given timeframe.
• The variables the researchers analyzed include breed, age, the specific surgical technique used, administration of general anesthesia, complications, the time from surgery to the occurence of complications, how complications were managed, and the final outcome.

Research Findings

• The surgical operation of perineal urethrotomy was mainly performed for treating urolithiasis (urinary stones), which accounted for 22 of the cases. Other reasons for the surgery included treating urethral injuries (3 cases), severe inflammation of the penis and prepuce (1 case), and bladder atony caused by a certain parasitic disease (1 case).
• 52% of the equids developed complications after the surgery. A significant complication was the recurrence of urolithiasis, noted in 23% of the animals.
• The study reveals certain postoperative measures significantly reduced the chance of complications. Horses that underwent postoperative cystoscopy (examination of the urinary tract) and bladder lavage (washout) were less likely to experience a return of urinary stones.
• However, a substantial 75% of equids that had a urinary catheter placed after surgery developed complications.

Conclusions

• The researchers conclude that perineal urethrotomy can be effectively used to treat urolithiasis, blood in urine, and urethral trauma in equids.
• They also highlight that conducting post-operative cystoscopy and bladder lavage significantly reduces the risk of post-operative return of urinary stones.
