Clinical Characteristics and Surgical Outcomes of Suspected Congenital Type II Phimosis in Two Cats

Phimosis is rarely reported in cats and involves the inability to exteriorize the penis through an absent or abnormally narrowed preputial orifice. This case report describes the clinical presentation, surgical management, and outcome of two male domestic shorthair kittens with suspected congenital type II phimosis. Both cats presented with recurrent stranguria and dysuria, preputial swelling, urine pooling or dribbling, a markedly stenotic preputial orifice, and penile–preputial adhesions. In Case 1, cystic struvite urolithiasis was also identified; treatment included cystotomy and ventrally performed modified preputial urethrostomy because of extensive adhesions, penile hypoplasia, and limited penile mobility. In Case 2, adhesions were limited to the distal penis and were released, allowing circumferential preputioplasty. No postoperative complications occurred. Clinical signs resolved, and normal urination was recorded during available follow-up, which was 12 months in Case 1 and 2 months in Case 2. The congenital origin was suspected based on early onset of clinical signs but could not be definitively confirmed. These cases suggest that selected feline type II phimosis cases can be managed successfully by tailoring surgery to anatomical abnormalities, using ventral-modified preputial urethrostomy when adhesions and penile hypoplasia restrict mobilization, or circumferential preputioplasty when adhesions are limited distally.
