Effects of urinary bladder retroflexion and surgical technique on postoperative complication rates and long-term outcome dogs with perineal hernia: 41 cases (2002-2009)

摘要

Objective—To evaluate the effects of urinary bladder retroflexion (UBR) and surgical technique on postoperative complication rates and long-term outcome in dogs with perineal hernia. Design—Retrospective case series. Animals—41 client-owned dogs with perineal hernia that underwent surgery between November 2002 and November 2009. Procedures—Medical records were reviewed for information on dog signalment, history, physical examination findings, ultrasonographic findings, surgical techniques, intraoperative complications, duration of hospital stay, postoperative complications, and long-term outcome. Results—31 dogs had no UBR, and 10 dogs had UBR. Internal obturator muscle transposition (IOMT) was performed in 20 dogs, and a cystopexy or colopexywas performed before the IOMT (LaplOMT) in 21. Postoperative complications included tenesmus (n = 8) and urinary incontinence (1). Rates of postoperative complications were not significantly different between the no-UBR and UBR groups or between the IOMTand LaplOMT groups. Thirty-two dogs were free of clinical signs at the time of the study. The median disease-free interval did not differ significantly between dogs in the no-UBR and UBR groups, but it was significantly lower in the LaplOMT group than in the IOMT group. None of the 7 dogs with UBR that were treated without cystopexy developed recurrence of UBR. Conclusions and Clinical Relevance—UBR was not associated with an increased rate of postoperative complications relative to no UBR and had noeffect on the long-term outcome in dogs with perineal hernia. The use of IOMT alone may be recommended for clinical use because LaplOMT offered no clear advantage.
