Objective To investigate the safety and efficacy of retroperitoneal laparoscopic heminephroureterectomy for duplex kidney.Methods A total of 15 patients underwent retroperitoneal laparoscopic heminephroureterectomy for duplex kidney from Jun 2003 to Dec 2006.Of the 15 cases,3 were male,12 were female,the average age was 32.3y(9-65 y).10 duplex kidneys were on the left,and 14 were on the upper pole.11 patients were found hydronephrosis by routine physical examination.3 complained of flank pain and fever.1 came to our hospital for urinary incontinence.14 were diagnosised by MRU,IVU or CT.One was misdiagnosised as renal cyst,and found duplex kidney during the operation.Results The mean surgical time was 130min(range 90-240min),and the mean estimated blood loss was 62.5 ml(range 30 - 500ml).The postoperative hospital stay was 8-9 days.Of the 15 cases,only one required conversion to open surgery.The mean postoperative intestinal functional recovery time was 1.8d(range 1-4d),and the mean postoperative hospital was 8.5 d(range 6-20 d mean).The normal pelvicalyceal injury was happened in one case,and one case underwent urinoma postoperatively.The blood urea nitrogen and creatinine before and after the operation had no statistical difference.The ultrasonagraphy after operation didn't find duplex kidney in all cases.Conclusions Retroperitoneal laparoscopic heminephroureterectomy for duplex kidney is effective and safe,and also had good postoperative results.
