后腹腔镜离断性肾盂成形术(附22例报告)

目的：探讨后腹腔镜离断性肾盂成形术的临床效果。方法：采用后腹腔途径对22例确诊为肾盂输尿管连接部(UPJ)梗阻的患者施行腹腔镜离断性肾盂成形术。结果：22例手术全部成功。手术时间70～180min，平均108min；术中出血量5～50ml，平均16ml；术后住院时间6～8d，平均7．2d。围术期无并发症。16例术后获随访3～15个月，UPJ吻合口无狭窄，肾积水得到改善。结论：后腹腔镜离断性肾盂成形术是治疗UPJ梗阻有效、安全及微创的方法，值得临床推广使用。

Retroperitoneal laparoscopic dismembered Anderson-Hynes pyeloplasty for the treatment of UPJ obstruction (Report of 22 cases)

Purpose:To assess the feasibility and results of retroperitoneal laparoscopic dismembered Anderson-Hynes pyeloplasty in the treatment of ureteropelvic junction (UPJ) obstruction.Methods:Twenty two cases with UPJ obstruction underwent retroperitoneal laparoscopic dismembered Anderson-Hynes pyeloplasty.Results:All the operations have been success. The mean operating time was 108 minutes (range from 70 to 180), the mean blood loss was 16 ml (range from 5 to 50) and the mean postoperative hospitalization days was 7.2 days (range from 6 to 8 ). No open conversions were required and no perioperative complication occurred. Radiographic assessment by intravenous urography 3 months after the procedure showed good results.Conclusions:Retroperitoneal laparoscopic dismembered Anderson-Hynes pyeloplasty is a safe and effective way to treat the UPJ obstruction while providing a minimally invasive procedure resulting in less morbidity, improved cosmesis and shorter convalescence. It is worth further clinical application.
