Trial Identification

Brief Title: Safety Study of Bipolar Versus Monopolar Transurethral Resection of Bladder Tumors

Official Title: Transurethral Resection of Bladder Tumors Without Obturator Nerve Block or Relaxation: Extent of Adductor Muscle Contraction With Monopolar Versus Bipolar Resection Technique

Study ID: NCT01446822

Conditions

Neoplasm of Lateral Wall of Urinary Bladder

Interventions

Bipolar transurethral resection of the urinary bladder (PlasmaKinetic, Gyrus, Fresenius)

Monopolar transurethral resection of the urinary bladder (Storz GmbH &Co., Erbotom, Purisole)

Study Description

Brief Summary: This is a single-center, prospective, randomized, controlled trial comparing two established transurethral electrical resection methods of urinary bladder tumors regarding their risk of stimulating the obturator nerve. One of the major safety issues with transurethral resection is bladder perforation as a consequence of obturator nerve stimulation followed by muscle contraction of. This is mostly a risk of resection of lateral bladder wall tumors near the course of the obturator nerve. It has been advocated that bipolar may be superior to monopolar resection, based on its different electrical properties. This is an important safety aspect for the patient. Main study question: In patients with lateral wall urinary bladder tumors, is bipolar superior to monopolar transurethral electroresection regarding risk of stimulation of the obturator nerve without preoperative nerve block?
