URETERAL STENT IN SEVERE HYDRONEPHROSIS OF PREGNANCY

Eleven women (12 pregnancies) were included in the study. A double-pigtail ureteric stent was passed under cytoscopic vision in 8 patients. The mean gestational age on insertion of the stents was 29 weeks (range, 25-35 weeks). Delivery took place at a mean of 39 weeks (range, 35-41 weeks). Stents remained in situ for a mean of 9 weeks (range, 6-14 weeks) before delivery and were removed 4-5 weeks postpartum Double pigtail ureteric stents did not expose the women to infection. Renal function tests remained within the normal limits. Ureteric stent is an effective method for internal drainage of severe hydronephrosis during pregnancy.
