Summary
Ureteroscopic procedures for ureteral calculi rarely cause strictures, even when stones are displaced retroperitoneally due to iatrogenic perforation. This complication is minor and typically does not require surgical intervention.
Area of Science:
- Urology
- Endourology
- Surgical Complications
Background:
- Ureteroscopy is a common treatment for ureteral calculi.
- Stricture formation is a known, albeit infrequent, long-term complication.
- Iatrogenic ureteral perforation can lead to paraureteral calculi.
Purpose of the Study:
- To determine the incidence of ureteral strictures following ureteroscopy.
- To investigate stricture formation in cases of retroperitoneal calculi caused by iatrogenic ureteral perforation.
Main Methods:
- A cohort of 15 patients with paraureteral calculi from ureteroscopic perforation was observed.
- Excretory urography was performed at a mean follow-up of 22.5 months.
- Patients received ureteral stents and postoperative antibiotics.
Main Results:
- Only one patient (1/15) developed a distal ureteral stricture.
- The stricture was successfully managed with endoscopic ureterotomy, balloon dilation, and stent placement.
Conclusions:
- Paraureteral calculi resulting from ureteral perforation are a minor complication of ureteroscopy.
- Stricture formation is rare in these cases and usually manageable with endoscopic techniques.
- Surgical removal of paraureteral calculi is generally not necessary.
