Perineal urethrostomy for management of congenital and acquired stenosed urethral orifice in two domestic short-hair cats

Two domestic short-haired cats two- and four-month-old were presented with a history of dribbling of urine. Both the animals were hyporectic and one animal showed vomiting. Physical examination revealed a distended urinary bladder in both cases. The urethral orifice was found to be very small with urine dribbling upon abdominal compression. From the history and physical examination the condition was diagnosed as a stenotic urethral orifice. Perineal urethrostomy under general anaesthesia was resorted to. The animals were stabilised with fluid therapy and antibiotics before surgery. An elliptical incision was made including scrotum and prepuce. Blunt and sharp dissection was employed to free the penile urethra from underlying structures. The urethra was split longitudinally to expose the lumen. Urethral mucosa was apposed to the skin using PDS 5-0 in an interrupted manner. Post-operatively antibiotic therapy was advised for 5 days. Diuretics and anti-inflammatory therapy were administered for 3 days. A review after 10 days revealed intact sutures, a patent perineal stoma and an active patient.
