Initial Experiences of Laparoscopic Nephrectomy in a Tertiary Oncology Center: An Analysis of 142 Cases.

Abstract

Kidney tumors have an important place among urological malignancies. The increased utilization of imaging methods has led to a rise in renal cell carcinoma (RCC) diagnoses, albeit with declining mortality rates, particularly in developed countries. Radical nephrectomy remains the gold standard treatment. The aim of this study was to share a tertiary oncology hospital's initial experiences with laparoscopic nephrectomy. This retrospective study analyzes data from patients who underwent laparoscopic nephrectomy, focusing on demographic characteristics, tumor features, and operative outcomes. Information regarding age, gender, tumor size, operative details, and pathology results was collected and analyzed. One hundred forty-two patients were included in the study; 69 (48.60%) were female and 73 (51.40%) were male. The mean age of the patients was 57.11 ± 12.6 years, with tumors primarily located on the left kidney (52.80%). The mean tumor size was 53.01 ± 24.01 mm. Intraoperative complications included the need for conversion to open surgery in five cases and vascular, pneumothorax, or duodenal injuries in a subset of patients. However, postoperative complications, such as sepsis or mortality, were not observed. Despite an initial learning curve associated with longer operation times, laparoscopic techniques offer benefits, including reduced blood loss, faster recovery, and improved cosmetic outcomes. Histologically, clear cell RCC was the most common tumor type encountered. This study underscores the safety and efficacy of laparoscopic radical nephrectomy, advocating for its widespread adoption while emphasizing the importance of surgeon experience and patient selection in optimizing outcomes.
