Complications associated with perineal urethrotomy in 27 equids.

Summary

# Editorial Summary: Perineal Urethrotomy Complications in Equids Between 2000 and 2010, Kilcoyne and Dechant reviewed 27 equine cases undergoing perineal urethrotomy, primarily for management of urolithiasis (n=22), with additional indications including urethral trauma, severe balanoposthitis, and neurogenic bladder dysfunction. Despite the procedure's utility in relieving obstructive and traumatic urinary conditions, postoperative complications occurred in 52% of cases, with recurrent urolithiasis representing the most significant issue at 23% of the urolithiasis cohort. A critical finding emerged regarding postoperative management: equids receiving both cystoscopy and bladder lavage immediately following surgery demonstrated significantly lower recurrence rates (P=0.039), whereas 75% of animals managed with indwelling catheters alone developed complications, suggesting this approach warrants reconsideration. For practitioners managing obstructive episodes or urethral trauma, perineal urethrotomy remains a viable salvage procedure, but success depends substantially on thorough intraoperative and postoperative bladder management—making aggressive cystoscopic evaluation and lavage essential components of the surgical protocol rather than optional adjuncts.
