Transurethral Hem-o-lok Clip Ligation of the Distal Ureter in Retroperitoneal Laparoscopic Radical Nephroureterectomy

Transurethral Hem-o-lok clip ligation technique provides a simple and safe option for distal ureter management in retroperitoneal laparoscopic RNU. This novel approach enables construction of a watertight system of the upper urinary tract, preventing the spread of tumor cells effectively and minimizing local tumor implantation risk.
