Introduction
Perineal urethrostomy is the creation of a new stoma of the urethra to the skin of the perineum for permanent diversion of urine. Indications for performing perineal urethrostomy include obstruction or rupture of the penile urethra. Five clinical cases of male dogs undergoing perineal urethrostomy were included in the present case series. The aim of the study was to describe the clinical signs, diagnostic investigation, surgical technique, complications, and long-term postoperative follow-up of 5 dogs with perineal urethrostomy.
Materials and methods
Five male dogs that underwent perineal urethrostomy in our Clinic, from 2000 to 2019, due to urethrodermal fistula, traumatic rupture of the penile urethra and recurrent obstructive urolithiasis were included in the study. The history, clinical signs, preoperative laboratory and imaging findings, surgical technique, postoperative complications, and long-term outcome were recorded.
Results
The dog suffering from recurrent obstructive urolithiasis presented with signs of dysuria and postrenal azotemia while the rest of the dogs were urinating from the wound site or through an urethrodermal fistula. The only early postoperative complication recorded was the occurrence of hematuria, with a median duration of 6 days. During the postoperative follow-up of a median duration of 3 years, which was achieved by re-examination or by phone contact with the owners, urinary tract infection was observed in 1 dog, while in the rest of the dogs no long-term postoperative complications were recorded.
Conclusions
It appears that the perineal urethrostomy in the male dog is an effective surgical technique, without serious postoperative complications, apart from expected postoperative bleeding.
