Retroperitoneal laparoscopic partial nephrectomy for treatment of cystic nephroma:one case report

囊性肾瘤（cysticnephroma）是临床上一种少见的。抒良性肿瘤，一般为多房性。文献对本病的手术治疗报道较少，北京大学第三医院泌尿外科于2013年11月收治1例，行后腹腔镜肾部分切除术，效果满意，现报告如下。

SUMMARY The clinical features and pathologic findings of one case of cystic nephroma was reported, and the safety of treatment by retroperitoneal laparoscopic partial nephrectomy evaluated. The patient was a 20-year-old woman, and found left renal cyst for 1 year with pain in her left flank one month ago. The patient was diagnosed as complex renal cyst, then underwent retroperitoneal laparoscopic partial nephrec- tomy. In the operation, the tumor was located in the middle and lower part of her left kidney, with a number of small sample masses, and a solid mass near the renal parenchymal part. The operation time was 224 min, and the artery occlusion time was about 17 min. The blood loss was 20 mL, with no blood transfusion. The pathology was cystic nephroma. No operation complication was seen, nor was recurrence after a short-term follow-up. Cystic nephroma is a relatively rare benign lesion of the kidney. Retroperito- neal laparoscopic partial nephrectomy is a safe and effective way to treat cystic nephroma.
