Objective: To compare the durations of surgery and anesthesia and the likelihoods of short- and long-term postoperative complications between cats positioned in sternal recumbency versus dorsal recumbency for perineal urethrostomy (PU)., Animals: 247 client-owned cats that underwent PU between January 2004 and December 2015 at 6 veterinary teaching hospitals and 1 private veterinary referral hospital., Procedures: Medical records were reviewed, and signalment, presenting complaints, previous history of urethral obstruction or PU, diet fed, medications administered, indication for PU, durations of surgery and anesthesia for PU, suture type and size, suture pattern for skin closure, and short- and long-term postoperative complications were recorded. Univariable and multivariable analyses were performed to identify differences in durations of surgery and anesthesia and the likelihoods of short- and long-term complications between cats positioned in sternal recumbency and those positioned in dorsal recumbency., Results: Patient position was not associated with durations of surgery and anesthesia for PU, even if a concurrent cystotomy was necessary or the patient required repositioning from sternal to dorsal recumbency. Likewise, patient position was not associated with the likelihood of short- and long-term complications., Conclusions and Clinical Relevance: The observed lack of differences in outcomes between sternal and dorsal recumbency suggested that logistic considerations and personal preference can continue to guide veterinarians when positioning cats for PU.
