CASE DESCRIPTION A 15-month-old male Newfoundland was examined because of an inability to urinate, lethargy, inappetence, and intermittent vomiting that first became evident after bilateral cryptorchidectomy 2 days previously. The patient referred for further evaluation treatment. CLINICAL FINDINGS Results physical examination, serum biochemical analysis, abdominocentesis led a diagnosis uroperitoneum. Retrograde cystography indicated urinary tract obstruction. In view the history recent elective cryptorchidectomy, uroperitoneum with urethral obstruction secondary iatrogenic prostatectomy urethrectomy made. TREATMENT AND OUTCOME During ventral midline celiotomy, inadvertent were found have resulted in insufficient length primary repair. Surgical repair defect achieved by means novel technique bladder retroversion neourethrocystostomy at apex bladder. stricture 1.5 months surgery initially treated balloon dilatation, followed temporary then permanent placement self-expanding metallic stent. At last follow-up 6.6 years stent placement, dog remained continent while receiving phenylpropanolamine owner highly satisfied outcome. RELEVANCE Caudal intraabdominal may be viable alternative more complex lengthening procedures dogs can potentially preserve lower function. This treatment might considered patients trauma or malignant neoplasia necessitating extensive resection. Urethral strictures effectively managed stenting.
