Pregnancy complicated by vesical calculus and vesicocutaneous fistula, ,

Bladder stones are a rare complication of pregnancy, with only 10 cases reported this century. This patient required a cesarean section for obstructed labor resulting from a 7 cm stone. Cystotomy with removal of the stone was performed with subsequent development of a vesicocutaneous fistula. (Am J Obstet Gynecol 1997;176:728-9.)
