Bladder Thermal Distention for Patients With Refractory Overactive Bladder (OAB)
Recruitment status was: Recruiting
In this study, the investigators will evaluate the efficacy of Bladder Thermal Distention (BTD) in patients with overactive bladder syndrome who failed previous treatment of anticholinergic drugs.
The investigators' hypothesis is that it will improve the storage symptoms.

Experimental: Bladder Thermal Distention
Continuous irrigation of the bladder with warm saline (up to 45 Celsius) using a specific 3 ways catheter. The procedure will last 1 hour. Saline will be irrigated by the PelvixTT system.
Procedure: Bladder Thermal Distention
Bladder Thermal Distention is an approved procedure in Europe from 2006. The treatment is hydrodistention of the bladder with a warm saline (up to 45C). The procedure lasts 1 hour. The saline is infused constantly through a 3 ways specific catheter (Unithermia 18F) by the PelvixTT system.
