Patients with renal tumors <7 cm and those at risk for a significant loss of renal function should be managed with a partial nephrectomy if it is technically feasible. Partial nephrectomy (PN) results in similar oncologic outcomes with radical nephrectomy.

In this section, we aimed to present the technical steps of laparoscopic partial nephrectomy
