Primary Vaginal Stones in an 11-Year-Old Girl

Primary vaginal stones are a rare finding in children and removal can sometimes be challenging. We describe an 11-year-old girl who was referred to our department for recurrent urinary tract infections and continuous urinary incontinence. Clinical and paraclinical examination revealed findings consistent with vaginal stones. Diagnostic studies of kidney and bladder function showed no abnormalities, but radiographs revealed a highly calcified mass exerting pressure on the bladder. Examination under anesthesia revealed no fistula, and urethrocystoscopy revealed no stones or abnormalities, except for a short, wide urethra pulled backward by a mass-like structure. After informed consent and double J catheter insertion, a second procedure to disintegrate the stones involved the insertion of a nephroscope into the vagina and the use of an ultrasonic device. Three-month follow-up showed resolution of incontinence. We recommend vaginoscopy to visualize the vagina and cervix and to facilitate instrumentation in young girls.
