title: [Extravesicular ectopia of the ureter].
abstract: The article provides detailed information on a rare malposition of the ureter--extravesicular ureteral ectopia (EUE)--concerning formation of the anomaly and clinical manifestations with reference to gender. EUE occurs more frequently in females, more frequently ectopic ureter drains upper part of the double kidney, less frequently--cavitary system of the non-double kidney. In males ectopic ureter drains cavitary system of the non-double kidney and falls in the posterior urethra, seminal vesicles, deferent duct. Fifty-six cases of EUE are analysed. Age of the patients varied from 6 months to 47 years. In group 1 of 49 females ectopic ureter in 47 of them drained an upper part of the double kidney (in 6 cases in both sides), in 2--the cavitary system of the non-double kidney. Of 7 males of group 2 ectopy was from the upper part of the double kidney, in 5--from non-double kidney. The percent of children with the anomaly among urological patients of the children's department for 26 years was 0.11 (52 out of 48756 children). All the patients were operated. 37 upper heminephrureterectomies were made in group 1 (in 1 case laparoscopic) as well as 5 nephrureterectomies and 5 ureteral reimplantations with preservation of the upper pole of the double kidney. 2 upper heminephrureterectomies and 5 nephrureterecmomies were performed in group 2. Short- and long-term results of urinary retention were good. 4 cases of EUE in males and females are reported.
