[Complete transperitoneal laparoscopic nephroureterectomy for upper urinary tract urothelial carcinoma].

OBJECTIVE:To discuss the surgical skills and clinical value of complete transperitoneal laparoscopic nephroureterectomy. METHODS:We collected and analyzed the clinical data of 25 patients (14 renal pelvic carcinoma and 11 carcinoma of ulreter, right side 15 and left side 10) who underwent complete transperitoneal laparoscopic nephroureterectomy for the upper urinary tract urothelial carcinoma (UUT-UC) in Peking University First Hospital from May 2010 to April 2011. RESULTS:All the operations were successfully done by one surgeon with standard 4 or 5 trocars technique. The mean operative time was 150 min (120-180 min), the blood loss about 20-100 mL (mean 40 mL) and no severe complications observed. The postoperative hospital stay was 4-6 days with an average length of 5.5 days. The mean follow-up was 5.5 (1-11) months. One of 19 patients underwent trans urethral resection of bladder tumour (TURBT) for recurrent non-muscle invasive bladder tumor. CONCLUSION:Complete transperitoneal laparoscopic nephroureterectomy is a minimally invasive, safe and effective way to treat UUT-UC. The patients recover soon and have a shorter length of stay.
