目的 :探讨经腹入路肾盂成形术的优点及适应证。方法 :对 2 6例 30侧经腹入路及 2 2例 2 4侧经腰入路两种离断式肾盂成形术围手术期临床指标及疗效进行对比观察。结果 :经腹入路手术切口时间、术中输血量、术后 2 4h肾周引流量及胃肠功能恢复时间等方面均优于经腰入路手术。结论 :对未合并肾脏畸形、肾周感染、结石及输尿管远端狭窄的单纯性肾盂输尿管连接部梗阻病人 ,经腹入路肾盂成形术优于经腰入路肾盂成形术 Objective: To investigate the advantages and indications of transabdominal pyeloplasty. Methods: Perioperative clinical indexes and curative effects of 26 cases of 30 sides transabdominal approach and 22 cases of 24 sides transumbilical approach were compared. Results: Transabdominal approach operation time, intraoperative blood transfusion, 24 h postoperative renal drainage and gastrointestinal function recovery time are better than transumbilical surgery. Conclusions: Transabdominal pyeloplasty is superior to transumbodial pyeloplasty in patients with simple ureteropelvic junction obstruction who have not been associated with renal malformations, perirenal infections, stones, and distal ureteral strictures
