Bilateral ureteral obstruction caused by vaginal foreign body: a case report.

PURPOSE: We present a case of a large, vaginal calculus which eroded into the bladder ultimately causing bilateral ureteral obstruction and acute renal failure.

MATERIALS AND

METHODS

A 34-year-old female presented with dysuria and urinary hesitancy. The diagnosis, workup, and treatment are outlined.

RESULTS

Consistent with radiographic findings, the stone was a primary vaginal stone which eroded into the bladder, the nidus of the stone being a vaginal foreign body. This vaginal stone, by eroding into the bladder, caused bilateral ureteral obstruction and renal failure.

CONCLUSION

A vaginal foreign body can grow so large that it can erode into the bladder and obstruct both ureters. This stone can be treated purely endoscopically, but a later fistula repair was required in this case. Recognizing this entity and instituting the appropriate treatment may enable this to be promptly managed with minimal patient morbidity.
