Perineal urethrostomy in a brown capuchin monkey (Cebus apella).

A 14-yr-old male brown capuchin monkey (Cebus apella) was presented to the Veterinary Teaching Hospital of the Hebrew University of Jerusalem, Israel, with stranguria. The history included distal urethral obstruction and a previous surgical attempt to create a urinary diversion through the perineum. A perineal urethrostomy was performed. In a 17-mo follow-up period, neither stranguria nor dysuria was observed, and the monkey's social behavior appeared normal. Perineal urethrostomy appears to be a simple and practical procedure in primates with a compromised distal urethra.
