title: Ureteric obstruction by the gravid uterus.
abstract: This paper reports the only 6 cases of ureteric obstruction apparently caused by the gravid uterus diagnosed at the Mercy Maternity Hospital in the past 17 years, during which time there were 82,836 confinements. In 3 of the 6 cases there was clear radiographic evidence that the level of obstruction was at the pelvic brim. The rapid resolution of the ureteric obstruction shortly after delivery strongly suggested that the gravid uterus was the cause of the obstruction. Cases 1-3 were the only patients of 793 with polyhydramnios who developed bilateral ureteric obstruction and acute renal failure. In Cases 4 and 5 there was unilateral ureteric obstruction and pyelonephritis; in Case 4 a ureteric catheter was inserted from below, and in Case 5 a ureteric stent was inserted via a nephrostomy tube. In Case 6 a percutaneous nephrostomy tube was inserted.
