Jack stone in the bladder: case report of a rare entity.

BACKGROUND

Jackstone is a bladder stone that has a similar appearance to toy jacks. However review of the English language medical literature revealed only a few previous reports of jackstone calculus.

CASE PRESENTATION: We report a case in which a large jackstone calculus was incidentally detected during the evaluation of 67 year old male presenting with lower urinary tract symptoms. X-Ray kidney, ureter, bladder showed a large irregular shaped radio-opaque shadow in the pelvic region. He underwent cystolitholapaxy and transurethral resection of the prostate.
