# Bladder Stone Formation Due to Suture Migration After Burch Colposuspension: A Case Report

## TL;DR

A woman developed bladder stones years after a stress incontinence surgery due to suture migration, which was successfully treated with laser lithotripsy.

## Contribution

Highlights suture migration as a rare but significant long-term complication of Burch colposuspension.

## Key findings

- Suture migration can occur years after Burch colposuspension and lead to bladder stone formation.
- Endoscopic holmium laser lithotripsy effectively removed stones and suture material, resolving symptoms.

## Abstract

Burch colposuspension is a well-established, mesh-free surgical technique for the treatment of stress urinary incontinence. Although lower urinary tract injuries may occur during the procedure, complications related to suture migration into the bladder are rare and may present years after surgery. We report a case of a 50-year-old woman who presented with a one-year history of progressive dysuria, suprapubic pain, and dyspareunia. She had undergone laparoscopic Burch colposuspension eight years earlier. Ultrasonography and computed tomography revealed bladder stones, and urethrocystoscopy demonstrated migrated polypropylene suture material within the bladder lumen serving as a nidus for stone formation. Endoscopic holmium laser lithotripsy was performed, and both the stones and suture materials were successfully removed. The patient’s symptoms resolved completely during follow-up. Suture migration following Burch colposuspension should be considered in patients presenting with chronic urinary symptoms and a history of incontinence surgery, regardless of the time elapsed since the procedure.
