Abstract

For small tumors under 7cm, laparoscopic nephron-sparing surgery is considered oncologically safe in cases of malignant tumors and has no difference with open surgery and even total nephrectomy. The majority of patients undergoing nephron-sparing surgery at the Department of Urology at Hanoi Medical University Hospital were selected via laparoscopy with or without the support of a robotic arm. We conducted a study to evaluate the results of this surgery. This is a retrospective description study of all patients undergoing laparoscopic nephron-sparing surgery at Hanoi Medical University Hospital from January 2020 to September 2023. Data were processed using R statistical software version 4.3.1. 34 patients were included in this study. Females were 1.4 times more likely than males (p < 0.001). The average age was 50.91 ± 14.36 years old. There were 5/34 patients (32.56%) in the intermediate risk group according to the RENAL scale. Surgery time was 95.14 ± 7.66 minutes (Min = 80; Max = 120). Warm ischemia time was 28.71 ± 7.44 minutes (Min = 20; Max = 150). The amount of blood loss was 70.42 ± 35.32ml. Postoperative hospital stay was 3.07 ± 0.49 days (Min = 2; Max = 4). The probability of no recurrence at month 3 was 96.7% (95%CI: 0.905 - 1). In conclusion, laparoscopic surgery after kidney-preserving tumor resection is a minimally invasive surgery, and is safe and effective.
