Are we using the right irrigation system?

The relationships between bladder pressure and irrigant fluid flow rate were tested using two commonly used supply systems and a 27 FG Storz resectoscope. Simple and inexpensive modifications would enable transurethral prostatectomy to be carried out with reduced intravesical pressure and less risk of fluid absorption. With a continuous suction resectoscope, the modified system allows accurate balance of the inflow and outflow of the irrigant fluid.
