Bladder stones are rare in pregnancy, and can be associated with adverse outcomes such as recurrent urinary tract infection and obstruction of labor. Management of bladder stones discovered in pregnancy has traditionally been done via open techniques such as cystolithotomy or with percutaneous removal. Our objective was to present a case of bladder stone in pregnancy and review prior reports on bladder stones and management in pregnancy.
CASE REPORT: A 28-year-old gravida 4 para 3 at 10 weeks gestation presented with dysuria, bladder spasm, weak urinary stream, and positional voiding. On first trimester ultrasound, a bladder stone (sized 3.7 cm) was identified and was confirmed by x-ray (KUB). Urology was consulted and removed the stone via cystolitholapaxy with holmium laser. Her symptoms subsequently resolved, and she went on to have an uncomplicated term spontaneous vaginal delivery. The removal of the stone enabled her to have a subsequent vaginal delivery without the potential for obstruction of labor.
CONCLUSIONS: Based on our review of the literature and this case report, laser cystolitholapaxy is a safe alternative to open surgery for the management of bladder stones in pregnancy. When discovered at the time of delivery, vaginal delivery is feasible if the stone is small or can be displaced. If encountered at time of cesarean delivery, then cystotomy with stone removal is recommended provided inflammation is not present.
