To evaluate the clinical performance of photodynamic diagnostic (PDD) after oral administration of 5-aminolevulinic acid (5-ALA) for assessment of tumor type and surgical margins in laparoscopic nephron-sparing surgery.This is a prospective, non-randomized single-center study. A total of 77 patients with a renal mass<4cm diameter underwent laparoscopic partial nephrectomy (LPN). For photosentization,...
