Urethral prolapse is a rare eversion of the distal urethral mucosa through the external urethral meatus. Surgical options reported include mucosal reduction and purse string placement, resection and anastomosis (RA) and urethropexy (UP). RA has a 56% recurrence rate, whereas data on UP are scant. The objective of this study is to compare the complication and recurrence rate of UP and RA for treatment of urethral prolapse in dogs.

Materials and methods
This retrospective study was granted ethical approval by the RCVS ethics review panel. Medical records of nine referral hospitals were reviewed. Dogs treated for urethral prolapse between 2012 and 2022 were included. A Fisher exact test was used to determine any significant association between different variables and the surgical techniques.

73 dogs were included: UP (n = 40), RA (n = 26)  and a combined surgical procedure (UPRA) (n = 7). Median follow-up was 386 days. Minor complications occurred in 38 dogs (52%). Major complication occurred in 21 dogs (28.8%). There was no significant difference in minor and major complications between groups. Recurrences accounted for 19 of the major complications: UP (n = 15, 37.5%), RA (n = 3, 11.5%) and UPRA (n = 1, 14.3%). Recurrences were significantly more likely in dogs treated via UP compared to RA (P = 0.019).

RA is associated with a lower recurrence rate in comparison to UP for the surgical treatment of urethral prolapse.
