[Hydronephrosis in pregnancy: importance of urologic actions and their volume].

In the present study, the data from 216 women with a complicated hydronephrosis of pregnancy who were treated at the Urology Department of the Vilnius City University Hospital between 1992 and 2001 have been subjected by us to a retrospective analysis and to an evaluation of the need for an interventional treatment and of the volume of the latter in the light of the special literature of the last decade of the XX(th) century. Both urologic observation and urologic management are required in the pregnancy hydronephrosis complicated by strong flank pains due to an acute dilatation of the upper urinary tract or by urolithiasis or pyelonephritis. An ultrasonographic investigation is the diagnostic mean of choice. The conservative management (hydration, spasmoanalgetics and antibiotics) gave positive results in 57% of cases, the retrograde stenting of the ureters was carried out in 41% of cases and the percutaneous or open nephrostomy (performed in 3 and 1 patients, correspondingly) in 2% of cases. During the management of the patients with a complicated hydronephrosis of pregnancy, the interdiscipline training of urologists and obstetricians-gynecologists as well as their close collaboration are of decisive importance.
