July/August 2014 Today's Veterinary Practice 45 PRACTICAL TECHNIQUES | FELINE PERINEAL URETHRoSToMy: VENTRAL APPRoACH 4 The penis is now reflected cranially, allow- ing the surgeon to work on its dorsal aspect (A). Identify the thin retractor penis muscle on the dorsal midline directly overlying the urethra (B). Carefully isolate it, and use a combination of blunt and sharp dissection with Metzenbaum or Stevens tenotomy scissors to free and transect its attach- ment to the penis (C). 3 With the penis pulled caudally, dissect the ventral connective tissue to isolate the paired ischiocavernosus muscles (A, asterisks), which attach the penis to the pelvis (see Surgical Insight: Ischiocavernosus Muscles ). Transect these muscles at their attachment to the ischium (B, dotted line); then sharply and bluntly dissect the ventral penile ligament until the penis can be freely retracted caudally from any ventrolateral pelvic attachments (C). SURGICAL INSIGHT: ISCHIOCAVERNOSUS MUSCLES » Sharp transection of the is- chiocavernosus muscles close to their ischial attach- ment limits hemorrhage from the body of the muscle. » Ventral dissection is consid- ered sufficient when the sur- geon can place a finger be- tween the penis and ischium within the pelvic canal. Pal- pate the space between the penis and ischium to con- firm sufficient ventral dis- section (A and B).
