¹Tiu uniforms procedures depending on the size of the neo-formations, in the first row showns formations < 4 cm in the second those > 4 cm;

²In these cases, authors specify the number of procedures that executed without ischemia from those in which the removal executed with ischemia. BMI: Body mass index; EBL: Estimate blood loss; OS: Conversion in open surgery; LPN: Laparoscopic partial nephrectomy; NA: Not attempted; VAS: Visual analogue scale; MLS: Multiport laparoscopic surgery.
