Labour dystocia: Vesical calculus can be the cause

Obstructed labour is a well-known clinical entity in maternity units, cephalopelvic disproportion being the most common cause. Here, we report a rare case of obstructed labour resulting from a large vesical calculus. The patient was a referred case from a district hospital for delayed progress of labour. The diagnosis of large vesical calculus causing labour obstruction was made by doing a vaginal examination. On vaginal examination, a large calculus of apparent size ~7 cm . 6 cm was palpated behind the anterior vaginal wall, which was preventing the descent of the head of the fetus. An emergency caesarean section was performed with simultaneous removal of vesical calculus by cystotomy. The postoperative period was uneventful.
