ABSTRACT
The literature regarding surgical repair of urethral prolapse in dogs is limited and associated with a high recurrence rate. We hypothesized that combined resection and anastomosis (R&A) with urethropexy would be associated with less recurrence of urethral prolapse compared with R&A alone. Medical records of dogs managed surgically for urethral prolapse were reviewed (2013–2023) from three tertiary care hospitals. Inclusion criteria included complete medical records, including surgery reports, short-term postoperative complications, and longer-term follow-up. Forty-six male dogs successfully met the inclusion criteria (16 castrated; 30 intact). Brachycephalic breeds were overrepresented (37/46, 80%). Surgical repair by R&A alone (n = 27), urethropexy alone (n = 6), or a combined R&A and urethropexy (n = 13) was performed. Recurrence rates for these techniques were 13/27 (48%), 2/6 (33%), and 1/13 (8%), respectively. The recurrence rate of urethral prolapse treated by a combined R&A and urethropexy was significantly lower (P < .05) than R&A alone, despite more dogs being overweight and less surgeon experience (each P < .05). Interestingly, dogs neutered before initial diagnosis may be more likely to have postoperative recurrence. Considering general anesthesia risks, an initial combination procedure for urethral prolapse may help prevent recurrence.
