Summary
Use of a bilateral caudal superficial epigastric skin flap and perineal urethrostomy
for reconstruction of a wound which occurred secondary to rupture of the distal urethra
and extravasation of urine is reported. A 10-month-old male neutered Domestic Shorthaired
cat was presented with a history of trauma, signs of pain of the hind quarters and
anuria. Progression of the clinical signs, including anuria, lethargy, anorexia, and
azotemia, prompted referral and investigation 108 hours following the initial injury.
Retrograde urethrography indicated a rupture of the distal pelvic urethra with extravasation
of urine subcutaneously. Development of extensive skin necrosis of the perineum and
rump progressed leaving a large wound defect which was managed with wound debridement
and dressing. The wound was closed using staged caudal superficial epigastric skin
flaps and perineal urethrostomy as part of the reconstruction.
