Abstract:
Background Partial nephrectomy (PN) is considered the standard treatment for small renal masses, providing superior oncological and functional outcomes compared with radical nephrectomy. While both open partial nephrectomy (OPN) and laparoscopic partial nephrectomy (LPN) are effective, minimally invasive techniques are gaining preference. Objective To analyze the perioperative complications and surgical outcomes of partial nephrectomy, with emphasis on its safety and efficacy. Method This retrospective study reviewed data from 26 patients who underwent partial nephrectomy for renal masses between January 2021 and December 2024, including 8 open partial nephrectomy and 18 laparoscopic partial nephrectomy. Collected data included tumor size, surgical margins, histopathological findings, ischemia time, and complications. Result The mean age was 53.7 years in the open partial nephrectomy group and 48.2 years in the laparoscopic partial nephrectomy group. Most tumors were detected incidentally, with clear cell renal cell carcinoma (ccRCC) being the most common histology (87.5% in open partial nephrectomy and 83.3% in laparoscopic partial nephrectomy). The mean tumor size was 29.5 mm in the open partial nephrectomy group and 32.9 mm in the laparoscopic partial nephrectomy group. Negative surgical margins were achieved in all cases. The mean operative time was 1.6 hours for open partial nephrectomy and 2.1 hours for laparoscopic partial nephrectomy, with mean warm ischemia times of 18.25 minutes and 20.6 minutes, respectively. The laparoscopic partial nephrectomy group had a shorter hospital stay (mean 4.7 days versus 5.3 days). Complications were minimal: one patient developed a renal artery pseudoaneurysm after laparoscopic partial nephrectomy, which was successfully managed with angioembolization. Conclusion In this small single-center series, partial nephrectomy, performed either laparoscopically or through an open approach, showed good surgical outcomes and perioperative safety in the management of small renal masses.
