Effect of Perineal Urethrostomy on the Length of the Urethra of the Cat: A Cadaveric Study.

Abstract

Ten male feline cadavers were used, and four markers were placed on the pelvic urethra via a ventral approach to the peritoneal and pelvic cavities. Two orthogonal radiographic views were acquired prior and subsequent to performing a PU. The distance of each marker to a predefined landmark/origin and the distances of the markers relative to each other were measured on all radiographs. PU resulted in significant caudal translation of the markers relative to the predefined landmark on all radiographic views; however, PU did not result in a significant change in the distances between the markers. Performing a PU results in caudal translation and minimal stretching of the mobilized pelvic urethra.
