Abstract

Objectives: To determine oncologic outcomes in terms of tumor free edges and surgical complications in patients undergoing laparoscopic "Zero ischemia" partial nephrectomy and renal tumor enucleation.

Methodology: Retrospective, observational, and comparative study, who underwent laparoscopic partial nephrectomy, were grouped into two groups: Group I: partial nephrectomy and Group II: enucleation, were analyzed: size and location of the tumor, RENAL score, surgical time, bleeding, days of stay, complications and histopathological report.

Results: 17 patients were evaluated, 3 were excluded due to radical surgery, 6 partial (Group I) and 8 enucleations (Group II). Mean age 45.7 (± 8.6) vs 51.2 (± 6.3) years. Tumor size 7.8 (2.5-10) vs 3.2 (1-5.7) cm, The overall RENAL score of all patients was low to moderate. There were differences in favor of group II (enucleation) in terms of surgical time and transoperative bleeding. As for surgical edges, there were 2 (14.2%) cases with positive edges, 1 for each approach, which are kept under close surveillance.

Conclusions: the laparoscopic approach is an option comparable to the open approach; equal results were obtained in terms of oncologic control in relation to free edges and with fewer complications.
