A total of 76 patients with hydronephrosis were enrolled in the study. Antegrade and retrograde ureteral stenting was used in 42 (55.2%) and 34 (44.8%) patients, respectively. In the first group after resection of the narrowed pyeloureteral segment (PUS) and formation of posterior wall of pyeloureteral anastomosis, antegrade stent was placed into the bladder, which followed by suturing of anterior wall of pyeloureteral anastomosis. While performing transurethral ureteral stenting, cystoscopy with retrograde ureteropyelography was carried out in lithotomy position, and the stent was put into the renal pelvis. Next, the patient was put into the lateral position, and LP was performed by transperitoneal access. There were no cases of conversion. The duration of the LP with antegrade stenting was significantly shorter than LP with retrograde stenting - 135 versus 170 minutes (p &lt;0.05). Differences in the blood loss (55 ± 20 and 60 ± 15 ml) and the length of hospital stay (5 ± 2 and 6 ± 1 day) were not statistically significant. In the group of retrograde stenting there were two cases of stent migration, which required repositioning of the stents. In one patient with antegrade stent placement, the distal end of the stent curled in ureterovesical junction. The stent position was corrected during the ureteroscopy. There was one case of antegrade stenting failure requiring ureteroscopy with retrograde ureteral stenting. Laparoscopic pyeloplasty is an efficient method of surgical management of patients with PUS narrowing. The duration of antegrade stenting was significantly shorter than retrograde stenting. LP with antegrade ureteral stenting as compared to LP with retrograde stenting enables significantly reduced surgery duration.</p></abstract><trans-abstract xml:lang="ru"><p>Проведена сравнительная оценка результатов лапароскопической пиелопластики (ЛП) в зависимости от способа стентирования верхних мочевых путей (ВМП). В исследование были включены 76 больных гидронефрозом. У 42 (55,2%) из 76 больных стент устанавливали антеградно, у 34 (44,8%) - ретроградно. В первой группе после резекции суженного пиелоуретерального сегмента (ПУС) и формирования задней стенки пиелоуретероанастомоза антеградно проводили стент до мочевого пузыря, ушивали переднюю стенку пиелоуретероанастомоза. При трансуретральном стентировании мочеточника в литотомическом положении выполнена цистоскопия с ретроградной уретеропиелографией, установлен стент до почечной лоханки. Далее больного переложили на бок, трансперитонеальным доступом выполнена ЛП. Конверсии не было ни в одном наблюдении. Продолжительность ЛП при антеградном стентировании была достоверно меньше, чем при ретроградном, - 135 мин против 170 (р&lt;0,05). Статистически значимых различий по объему кровопотери (55±20 и 60±15 мл) и времени госпитализации (5±2 и 6±1 день) не было. В группе ретроградного стентирования имело место два случая миграции стента, который был установлен заново. В группе антеградной установки стента у одного пациента дистальный конец стента свернулся в юкставезикальном отделе мочеточника, выполнено его низведение уретероскопом. Другому больному антеградно не удалось установить стент, поэтому произведена уретероскопия с ретроградным стентированием мочеточника. Лапароскопическая пиелопластика - эффективный способ оперативного лечения больных с сужениями ПУС. Время операции при антеградном дренировании мочеточника достоверно меньше, чем при ретроградной установке стента. Антеградное стентирование мочеточника во время лапароскопической пиелопластики по сравнению с ретроградной методикой установки стента позволяет достоверно уменьшать время операции.</p></trans-abstract><kwd-group xml:lang="en"><kwd>pyeloureteral segment</kwd><kwd>stricture</kwd><kwd>plasty</kwd><kwd>laparoscopy</kwd><kwd>stenting</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>пиелоуретеральный сегмент</kwd><kwd>стриктура</kwd><kwd>пластика</kwd><kwd>лапароскопия</kwd><kwd>стентирование</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Rassweiler J., Subotic S., Feist-Schwenk M., Sugiono M., Schulze M., Teber D., Frede T.
