Prone flexible cystoscopy: an adjunct to percutaneous stone removal

Area of Science:

• Urology
• Minimally Invasive Surgery

Background:

• Percutaneous renal calculi removal often requires retrograde ureteral catheterization.
• Traditional methods involve rigid cystoscopy and patient repositioning from dorsal lithotomy to prone.

Purpose of the Study:

• To evaluate the feasibility and effectiveness of using a flexible cystoscope with the patient in a prone position for retrograde ureteral catheter placement.
• To assess the impact on operating room efficiency and patient management.

Main Methods:

• Flexible cystoscopy was performed with patients in the prone position for retrograde ureteral catheter placement.
• The approach was attempted in both male and female patients.
• Outcomes were compared to traditional supine or repositioning methods.

Main Results:

• The prone approach was difficult in male patients due to urethral anatomy.
• In female patients, the prone approach was easily performed.
• Female patients experienced decreased operating room time and less manipulation.
• A two-tiered sterile field was created, enhancing catheter sterility.

Conclusions:

• The prone flexible cystoscopy approach for retrograde ureteral catheterization is feasible and effective in female patients.
• This technique offers benefits in terms of efficiency and patient handling for female patients undergoing percutaneous stone removal.
