Objective To explore the characteristics and clinical application of retroperitoneal laparoscopic nephrectomy of nonfunctional kidney with giant hydronephmsis.Methods Totally 50 patients with no functional renal caused by giant hydronephrosis from May 2013 to November 2014 were randomly divided into observation group (25 cases) undergoing retroperitoneal laparoscopic nephrectomy and control group (25 cases) undergoing traditional operation.The duration of operation, intraoperative blood loss, time of ambulation and hospital stay time were compared between the two groups.Results The duration of operation in observation group was significantly shorter than that in control group [(105 ±25) min vs (134 ±28) min] (P ＜0.01).The intraoperative blood loss in observation group was significantly less than that in control group [(56 ± 14) ml vs (118 ± 26) ml] (P ＜0.01).The time of ambulation in observation group was significantly shorter than that in control group [(2.2 ±0.8) d vs (5.2 ± 1.7) d] (P ＜0.01).The stay time in hospital in observation group was significantly shorter than that in control group [(4.9 ± 1.5) d vs (8.1 ±2.2) d] (P＜0.01).Conclusion Retroperitoneal laparoscopic nephrectomy of no functional renal caused by giant hydronephrosis is safe and feasible with light trauma,less bleeding, and quicker recovery.%目的 探讨巨大肾积水致无功能肾腹膜后腹腔镜下肾脏切除术的特点及临床应用.方法 选取广州市番禺区何贤纪念医院2013年5月至2014年11月因巨大肾积水致无功能肾行切除术患者共50例,按照随机数字表法分为观察组和对照组,各25例.对照组采用传统肾切除术,观察组采用腹膜后腹腔镜下肾切除手术.比较2组患者手术时间、术中出血量、术后下床活动时间和住院时间.结果 观察组患者手术所用平均时间为(105±25) min,对照组为(134±28) min,观察组明显短于对照组,差异有统计学意义(P＜0.01);观察组患者术中平均出血量为(56 ± 14) ml,对照组为(118 ± 26) ml,观察组明显少于对照组,差异均有统计学意义(P＜0.01).观察组患者术后平均下床活动时间为(2.2±0.8)d,对照组为(5.2±1.7)d,观察组明显短于对照组,差异有统计学意义(P＜0.01);观察组患者平均住院时间为(4.9±1.5)d,对照组为(8.1±2.2)d,观察组明显短于对照组,差异有统计学意义(P＜0.01).结论 巨大肾积水致无功能肾腹膜后腹腔镜肾脏切除术具有创伤轻、出血少、术后康复快特点,是安全可行的一种临床治疗途径.
