Optical valvulotomy for urethral valves using a hook-blade cold knife.
Endoscopic disruption of urethral valves remains a mainstay of the pediatric urologic armamentarium. We describe transurethral optical valvulotomy using a hook-blade cold knife as a safer alternative to valve resection using a wire loop electrode. This technique offers precise control of the resection process and freedom from inadvertent injury to the urethra or sphincter due to a "hot" electrode.
