Acute renal failure from complete uterine prolapse: role of polycystic kidney disease.

A 48-year-old female developed acute renal failure from obstruction caused by a complete uterine prolapse. She had polycystic kidney disease (ADPKD) with previously stable mild renal impairment. She presented with rapidly declining renal function and oliguria which reversed following manual reduction of the prolapse and insertion of a ring pessary. None of the usual risk factors for uterine prolapse were present, however ADPKD may have contributed to the prolapse. Rapid deterioration of renal function in female patients with ADPKD should prompt gynecological examination to exclude a uterine prolapse as a cause.
