Arms Assigned Interventions
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.
