Vesicovaginal fistula and bladder calculus formation secondary to long-term retention of an intrauterine device

Introduction

Although uterine perforation is a rare but serious complication, intrauterine devices are globally popular and effective contraceptive methods.

Case presentation

A 76-year-old female patient manifesting symptoms of vaginal leakage and lower abdominal discomfort was admitted to our hospital. Diagnostic imaging identified a vesicovaginal fistula and bladder calculi attributable to perforation of the bladder by an intrauterine device that had been inserted over four decades ago. The patient underwent open surgery for cystolith removal and vesicovaginal fistula repair.

Conclusions

If a patient with an intrauterine device complains of bladder stones or ongoing lower urinary tract symptoms, bladder perforation caused by the device should be considered in the differential diagnosis.
