Ventral onlay graft urethroplasty using bladder mucosa in a cat with a urethral stricture

A 3-year-old, 4.0 kg, intact male domestic shorthair cat presented with postoperative dysuria following urethral resection and anastomosis for urethral rupture. Retrograde urethrography revealed a stricture in the pelvic urethra. Urethroplasty with bladder mucosa was performed following a bilateral...

Description
Summary:A 3-year-old, 4.0 kg, intact male domestic shorthair cat presented with postoperative dysuria following urethral resection and anastomosis for urethral rupture. Retrograde urethrography revealed a stricture in the pelvic urethra. Urethroplasty with bladder mucosa was performed following a bilateral pubic-ischial osteotomy. The bladder wall was resected to harvest an appropriately sized bladder mucosa graft. The graft was placed over the urethral defect in patch fashion and stabilized with interrupted sutures. The cat was able to urinate normally with no evidence of lower urinary tract signs 2 year postoperatively. Therefore, urethroplasty with an onlay bladder mucosa graft may be a feasible alternative to prepubic or subpubic urethrostomy for the treatment of pelvic urethral stricture in cats.
