Hand-assisted retroperitoneoscopic radical nephrectomy and nephroureterectomy.

In laparoscopic operations for renal tumor and upper urinary-tract transitional-cell carcinoma (TCC), three approaches - the transperitoneal, retroperitoneal, and transperitoneal hand-assisted - have been reported. We have performed hand-assisted retroperitoneoscopic radical nephrectomy (RN) since 1999 and nephroureterectomy (NU) since 2000. The surgical techniques and the operative results of 95 cases of RN and 54 cases of NU are described and analyzed. These procedures were effective and safe for renal tumors and upper urinary-tract TCC.
