Surgical Management of Obstructive Urolithiasis by Perineal Urethrostomy in a Tom Cat

A 2 year old intact domestic tom cat weighing 4.75 kg was referred to Small Animal Surgery Out Patient unit of Madras Veterinary College Teaching Hospital with the history of intermittent licking of its genitalia, hematuria and stranguria with progressive reduction in appetite for the past two weeks. Clinical examination revealed a distended, tensed abdomen, which on palpation, depicted bladder involvement that was painful and unresponsive to manual decompression. A distended obstructive bladder was noticed along with dorsal and cranial displacement of adjacent organs on a lateral and ventrodorsal abdominal radiograph, in addition ultrasonography was performed to rule out bladder epithelial health. On ultrasound thickened bladder wall with non shadowing sediments along with a dilated pelvic urethra was noticed in addition to an hyperechoic mass obstructing the distal penile urethra. Based upon the radiograph and ultrasonographic findings the case was tentatively diagnosed as obstructive urolithiasis
