后腹腔镜手术治疗16例肾盂旁囊肿

目的探讨后腹腔镜手术治疗肾盂旁囊肿的疗效。方法2005年8月～2008年12月16例肾盂旁囊肿行后腹腔镜囊肿去顶减压术。采用全身麻醉,经后腹腔途径建立后腹腔操作空间,沿输尿管寻找到肾盂旁囊肿,距正常肾实质3～5mm处行囊肿去顶。结果15例手术成功,手术时间（75±20）min,术中出血量（28±8）ml,未出现肾蒂及肾盂损伤等并发症;1例因囊肿暴露困难中转开放手术。16例术后随访6～20个月（平均13个月）,均未见复发。结论后腹腔镜治疗肾盂旁囊肿微创、安全、有效。

Retroperitoneal Laparoscopy Deroofing for Parapelvic Cyst: Report of 16 Cases

Objective To explore the efficacy of retroperitoneal laparoscopy in the treatment of parapelvic cyst. Methods From August 2005 to December 2008, 16 cases of parapelvic cyst were treated by retroperitoneal laparoscopic deroofing and decompressing in our hospital. Under general anaesthesia, an operational space was established via retroperitoneal route. And then, along the urethra, the parapelvic cyst was explored. Afterwards, the cyst was unroofed 3 to 5 mm from the normal renal tissues. Results The operation was completed in 15 of the patients with a mean operation time of （75 ± 20） minutes and mean blood loss of （28 ± 8） ml. No injuries to the kidney pedicle or pelvis occurred. Another patient was converted to open surgery because of difficulty in exposure of the cyst. This series were followed up for a mean of 13 months （range, 6 to 20 months）. No one had recurrence during the period. Conclusions Retroperitoneal laparoscopie deroofing is minimally invasive, safe and effective or parapelvic cyst. It should be the first choice for the disease.
