Perineal urethrostomy in male dogs - Technique description, short- and long-term results.

The perineal urethrostomy (PU) technique has only been vaguely described in the dog. Additionally, details of short- and long-term postoperative complications are not well documented. The purpose of this study was to provide a detailed description of PU in male dogs and describe the post-operative course. Eight adult, intact, male, mixed-breed dogs were used for this study. A perineal urethrostomy was performed on each, using the described technique. Dogs were assessed daily for 70 to 419 d after surgery, and stoma site patency was assessed at planned intervals using a 12 French Foley catheter as well as a 5.5-mm rigid cystoscope. Surgical time and short- and long-term complications were recorded. The perineal urethrostomy stoma sites of all 8 dogs were determined to be patent and no strictures were identified during the entire time course of this study. No major complications occurred during the follow-up period. Three dogs developed minor, self-resolving incisional dehiscence. The mean surgery time was 62.9 ± 14.1 minutes (mean ± SD). Canine perineal urethrostomy as described can be performed with minimal short- and long-term complications.
