Summary
Ureteroscopic lithotripsy without ureteral dilatation is effective for stones in all ureteral locations. This minimally invasive approach achieved high stone-free rates with no ureteral perforations or strictures.
Area of Science:
- Urology
- Endourology
- Minimally Invasive Surgery
Background:
- Ureteral stones are a common condition requiring effective treatment.
- Ureteroscopic lithotripsy is a standard procedure for stone removal.
- Ureteral dilatation is often used to facilitate ureteroscope insertion.
Purpose of the Study:
- To evaluate the efficacy and safety of ureteroscopic lithotripsy without ureteral dilatation.
- To assess stone-free rates for ureteral stones in different locations.
- To determine the feasibility of performing ureteroscopy without prior ureteral preparation.
Main Methods:
- 134 patients with ureteral stones underwent semirigid ureteroscopy (8 F) without dilatation.
- Pneumatic lithotripsy was used for stone fragmentation.
- Basket catheter or stone forceps were used for fragment removal.
Main Results:
- High stone-free rates were achieved: 97% for lower, 83% for middle, and 75% for upper ureteral stones.
- Mean operation time was 44 minutes.
- No ureteral perforations or strictures were observed postoperatively.
Conclusions:
- Ureteroscopic lithotripsy can be safely and effectively performed without ureteral dilatation for stones in all parts of the ureter.
- This technique offers a minimally invasive option with good outcomes.
- Further studies can explore long-term outcomes and patient-reported benefits.
