Obstructed labor in this case has been reported because of
its rarity as the cause was a large vesical calculus, which
was diagnosed during the second stage of labor.
The patient was gravida eight para five who had a history
of urgency and hematuria antenatally. During labor an
attempt at passing a catheter was unsuccessful, and a
vaginal examination showed a large hard mass bulging into
the vagina anterior by. This mass was suspected to be a
large bladder calculus. At cesarean section which was
performed for obstructed labour. The mass was confirmed
as to being located within the bladder (Figs. 1, 2, 3). A
cystotomy was performed for the removal of a large calcium oxalate, uric acid stone weighing 156 g and measuring 6.8 9 5.8 cm.
Vesical calculi can exceptionally cause obstetrical dystocia [1]. Vesical calculi are uncommon in woman and rare in pregnancy [2]. The common complications are infections, premature deliveries, abortions, urinary fistula and uterine rupture [1, 2]. Management varies according to the size and situation of the calculus and whether the patient is in labor. Suprapubic cystotomy is the safest approach for removal of a large calculus [3].
