title: [Retroperitoneal laparoscopy combined with urethral resection for treatment of renal pelvic carcinoma].
abstract: OBJECTIVE
  The purpose of this study is to explore the operation method and efficacy through retroperitoneal laparoscopy combined with urethral resection for treatment of renal pelvic carcinoma.
  
  
  METHODS
  Total nephroureterectomy with excision of bladder cuff by retroperitoneal laparoscopy plus urethral resection was performed in 18 patients with pathologically confirmed pelvic transitional cell carcinoma (II-III, T1N0M0-T2N0M0). The operation was performed using Olympus celioscope (30 degrees or 0 degree) under general anesthesia. First, a 10 mm incision was made at the intersection of midaxillary line and superior border 2 cm from crista iliaca, then a self-made hyponome filled with 250-300 ml water was put through the small incision in order to open the retroperitoneal space, followed by getting the hyponome out and perfusing CO2 into the retroperitoneal space to make a pneumoretroperitoneum. Finally, the celioscope was put into the retroperitoneal space to operate. During the operation, electric coagulation was used to stop bleeding and the bladder was not irrigated.
  
  
  RESULTS
  The operation was successfully performed in 18 patients without any complication. The operative time ranged from 150 to 190 min with a mean of 160 min. The hospital stay after operation was 7 to 10 days. There was no tumor recurrence or metastasis or implantation in all these patients after follow-up of 1-19 months.
  
  
  CONCLUSIONS
  Compared with regular operation mode, retroperitoneal laparoscopy plus urethral resection for treatment of renal pelvic carcinoma is a minimally invasive treatment with less bleeding and quick recovery.
