Summary
Pre-laparoscopic cholecystectomy bladder catheterization is unnecessary. Measured residual urine volumes are too small to risk bladder perforation during laparoscopic surgery.
Area of Science:
- Surgical Procedures
- Urology
Background:
- Routine bladder catheterization is often performed before laparoscopic procedures.
- Concerns exist regarding potential bladder injury during trocar insertion.
Purpose of the Study:
- To assess the volume of residual urine in patients undergoing laparoscopic cholecystectomy.
- To determine if pre-operative catheterization is necessary to prevent bladder injury.
Main Methods:
- Fifty patients undergoing laparoscopic cholecystectomy had residual urine measured via catheterization prior to surgery.
- Bladder volume was assessed immediately before the procedure.
Main Results:
- The median residual urine volume was 100 ml (range: 5-500 ml).
- This volume was insufficient to significantly distend the bladder and pose a perforation risk.
Conclusions:
- Pre-operative urinary bladder catheterization is not required before laparoscopic cholecystectomy.
- The risk of inadvertent bladder perforation during subumbilical port insertion is minimal, especially when the bladder is impalpable.
