Ureteroureterostomy in case of renal duplication.

Introduction. Kidney duplication is one of the most common urological developmental anomalies, incidence which 0.8%. At same time, various types obstructive uropathy can be a concomitant pathology in such situation. There are methods for correcting uropathy. Currently, more and often treatment segments doubled kidney, method as ureteroureterostomy used. However, there still no consensus on tactics this case optimal. The aim our work was to analyze literature about using patients with uropathies duplicated well compare technique others. Materials methods. Search results were analyzed scientific databases e-Library, PubMed, Medline, Web Science, Embase, Cochrane Library PEDro according following. keywords: «renal duplication», «heminephrectomy», «ureteroureterostomy», «obstructive uropathies». In total it found 157 publications, after analyzing literature, 33 papers selected review, fully reflecting topic. Results. Heminephrectomy popular severely reduced or absent duplex kidney function, but has complications decreased function remaining segment, pseudocyst formation, stump, urinoma, segmental hematoma, ureteral stricture, vesicoureteral reflux into segment. Ureteroureterostomy, an alternative double been recognized effective safe many studies. Data presented prove that applicable any affected article, techniques consecrated, from open intervention robotic one. addition, research data safety ureteroureteroanastomosis pronounced discrepancy between diameters ureters presented. Among ureteroureteroanastomosis, cultitis, urine leakage anastomosis zone, stenosis noted. predictors unfavorable outcome proposed identified. These include ectopic ureterocele, hydronephrosis both simultaneous reimplantation recipient ureter. Conclusions. Ureteroureterostomy pathologies inherent allows preserving segment adequately draining it. use does not depend presence decrease lack segments.
