[Is ureteral dilatation necessary in ureterorenoscopy?]
Summary
Routine balloon dilation before ureteroscopy for kidney stone removal is not necessary. A study found similar success rates and no increased risk of vesico-renal reflux in patients undergoing ureteroscopy with or without prior ureter dilation.
Area of Science:
- Urology
- Endourology
- Nephrolithiasis Management
Context:
- Rigid ureteroscopy is a common procedure for kidney stone removal.
- The intramural portion of the ureter can present a challenge during ureteroscopy.
- Pre-procedure dilation techniques are sometimes employed to facilitate ureteroscopy.
Purpose:
- To evaluate the necessity of routine balloon dilation of the intramural ureter prior to rigid ureteroscopy for stone removal.
- To compare the efficacy and safety of ureteroscopy with and without pre-procedure dilation.
Summary:
- A retrospective analysis of 136 patients undergoing rigid ureteroscopy for stone removal was conducted.
- Patients were divided into two groups: one with routine balloon dilation (63 patients) and one without (73 patients).
- Total success rates were comparable (90.5% vs. 91.8%), with similar stone removal efficacy across ureter segments and no reported vesico-renal reflux in either group.
Impact:
- Findings suggest that routine balloon dilation of the ureter before rigid ureteroscopy may not be a necessary step.
- This could potentially streamline the procedure and reduce associated costs or complications.
- Further research may confirm these findings and influence clinical practice guidelines for ureteroscopy.
