Abstract
BackgroundThe aim of this study was to analyze the feasibility and the safety of laparoscopic nephrectomy in the treatment of pathologies of the upper urinary tract through the experience of the Urology B department.MethodsWe have retrospectively and monocentrally selected patients who underwent laparoscopic nephrectomy from January 2017 to December 2019. The collection was carried out on archived files, based on demographic, clinical and perioperative data. The primary endpoint was the occurrence of complications and secondarily the length of the operation and the length of hospital stay. The statistical analysis was carried out using the SPSS software.ResultsA total of 68 patients were included in our series. The average age of our patients was 57.8 years. There was a slight female predominance: 39 female patients (57.4%) for 29 male patients (42.6%). Indications for nephrectomy were dominated by renal tumor (33.82%) followed by lithiasis (16.17%) and non-functioning kidney (16.17%) at the same rank. During the study period, 31 (45.6%) simple nephrectomy, 26 (38.2%) total nephrectomy, 1 (1.5%) partial nephrectomy and 10 (14.7%) nephroureterectomy were performed in our department. In our series, the average operating time was 180 min. Estimated blood loss averaged 321.8 ml with extremes of a few milliliter to 1100 ml. Intraoperative complications were reported in 10 (14.7%) patients; conversion was necessary in 6 cases (8.82%). The postoperative follow-up was straightforward in 53 (77.94%) patients with an average hospital stay of 3.6 days. The rate of postoperative complications according to Clavien–Dindo was 22.1%. Histological examination of the nephrectomies carried out in our department revealed mainly chronic non-specific pyelonephritis in 24 (35.3%) patients, followed by renal cell carcinoma in 23 (33.82%) patients and urothelial carcinoma in 9 (13.2%) patients.ConclusionLaparoscopic nephrectomy appears to be an efficient and reliable technique. This technique has led to a significant improvement in operative morbidity, mainly represented by the length of hospital stay, operating time and blood loss.

Summary
Since the advent of laparoscopic surgery, many procedures have been described and performed with varying success. When it comes to urology, it all started when Ralph Clayman performed the first laparoscopic nephrectomy in 1991 [1]. He had chosen the transperitoneal (TP) route to perform a right nephrectomy, and during the same year, Ferry performed a left nephrectomy by the same route [2, 3]. In 1993, Gaur proposed the retro-peritoneal (RP) approach to perform laparoscopic nephrectomy [4]. Laparoscopic nephrectomy has undergone significant development, whether performed trans or retroperitoneally, with or without robot assistance. The operative consequences of this technique remain simple, less painful, and the recovery time is shorter than open surgery
