    Abstract:
    PURPOSE: The aim of the study was to report the surgical complications that may occur during or after primary ablation of posterior urethral valve (PUV) in a large number of cases treated using different modalities. MATERIALS AND METHODS: We retrospectively reviewed a database of 291 patients with PUV treated by primary valve ablation from 2 separate centers between 1987 and 2006. Primary valve ablation was performed in all patients regardless of serum creatinine level or upper tract configuration. A hot loop resectoscope was used in 122 patients, cold knife urethrotome in 108, a hook diathermy electrode in 18, a diathermy coagulation bugbee electrode in 20, whereas stripping using a Fogarty catheter was performed in 23. RESULTS: The follow-up duration ranged from 1.5 to 20 years (median, 6.5). Early postoperative complications occurred in 22 patients (7.5%). The most common complication was urinary retention in 16 patients (5.5%). Urinary extravasations occurred in 3 cases, significant hematuria from urethral bleeding occurred in 2, and obstructive anuria developed in 1 patient. Most of cases were treated conservatively. Urethral strictures developed in 6 patients (2%) mainly after endoscopic loop resection (4/6). All were treated by visual internal urethrotomy and urethral dilatation with successful results without the need of open urethroplasty. CONCLUSIONS: Primary valve ablation seems to be safe and is associated with low rate of postoperative complications. All the complications could be treated conservatively. Urethral stricture may occur after valve ablation in a minority of cases and can be successfully treated endoscopically. Loop resection is associated with more strictures.
