Are we using the right irrigation system?

Area of Science:

• Urology
• Surgical Engineering

Background:

• Transurethral prostatectomy (TURP) involves risks associated with irrigant fluid management.
• Elevated intravesical pressure during TURP can lead to fluid absorption and complications.

Purpose of the Study:

• To investigate the relationship between bladder pressure and irrigant flow rate during TURP.
• To evaluate the efficacy of simple modifications for reducing intravesical pressure and fluid absorption.

Main Methods:

• Testing irrigant fluid flow rates and bladder pressures using two standard supply systems and a 27 FG Storz resectoscope.
• Implementing and assessing modifications to the irrigant supply system.
• Utilizing a continuous suction resectoscope for fluid management.

Main Results:

• Identified relationships between bladder pressure and irrigant fluid flow rates.
• Demonstrated that simple, inexpensive modifications significantly reduce intravesical pressure.
• Showcased the ability of a modified continuous suction system to balance irrigant inflow and outflow.

Conclusions:

• Simple modifications to standard equipment can enhance the safety of transurethral prostatectomy.
• Reduced intravesical pressure minimizes the risk of irrigant fluid absorption.
• Optimized irrigant flow management is achievable with modified continuous suction systems.
