Necrosis of the distal penis was found in 4 animals and all were short\u2010term non\u2010survivors. Short\u2010term survival for surgical cases was 65%, and 57% for medical cases. Incomplete urethral obstruction at admission and surgical treatment were associated with increased odds of short\u2010term survival. Of 14 records available for long\u2010term follow\u2010up, 6 animals were alive and 8 were dead (median follow\u2010up 4.5 years, median survival time 2.5 years).
