Today's Veterinary Practice July/August 2014 44 | PRACTICAL TECHNIQUES tvpjournal.com 1 Position the cat in dorsal recumbency (see Surgical Insight: Penile Orien- tation ) with the hindlimbs tied cra- nially until the pelvis is slightly elevated off the surgery table. Place a folded towel under the pelvis to support the patient (A and B) and place a purse string suture in the anus. Clip and aseptically prepare the perineal region ± ventral abdomen (if a cystotomy is indicated). 1A 1B SURGICAL INSIGHT: PENILE ORIENTATION » Pay close attention to penile orien- tation in this technique (ie, dorsal versus ventral side). » When the penis is pulled caudal- ly, toward the tail, the surgeon is working on its ventral aspect. » When the penis is reflected cra- nially, toward the cat's head, the surgeon is working on the dorsal aspect. » Minimal delicate peripenile dissec- tion is carried out on the dorsal as- pect of the penis, as this is where the primary neurovascular supply is located. 3 » When dissecting the dorsal as- pect of the penis, the surgeon is also in close proximity to the rec- tum, which is undesirable because it increases the risk of rectal per- foration 2 If the cat is intact, perform a routine castra- tion. The urethra can be catheterized with a Tomcat catheter to aid identification and manipulation. Make a symmetric, elliptical incision around the scrotum and penis (A) at the junction of the perineal and scrotal skin. Perform a circumferential dis- section of the subcu- taneous connective tissues to isolate the penis (B). 2A 2B Cranial Caudal
