[Internal drainage of urine in cases of complicated urinary stasis caused by pregnancy].
In 14 women with sympthomatic hydronephrosis due to pregnancy (calyx diameter 1-2,6 cm) an internal urinary drainage was carried out during the second half of pregnancy. Retrograde stenting was placed per cystoscopy in all cases. Follow-up examinations were taken weekly for the first two weeks and further on biweekly. Primary stenting was possible in 12 out of 14 cases, and in two patients dilatation of the ureteral orifice was necessary. 11 out of 14 patients suffered from complications such as severe dysuria (9), urinary tract infection (7), persisting lumbar pain plus catheter lumen obstruction (6 each) as well as catheter migration (3). Long-term follow-up showed that urinary tract obstruction was relieved by stenting in only 6 out of 14 patients. Sufficient urinary drainage by so called double-J ureteral stents was achieved in less than half of the cases. Moreover, there was a complication rate of more than 75%. Taking these results into consideration, internal drainage of complicated pregnancy hydronephrosis needs careful evaluation.
