Comparison of modified hand-assisted retroperitoneoscopic laparoscopic nephrectomy and open nephrectomy in patients with benign inflammatory non-functioning kidney diseases.

Abstract

BackgroundTo assess the validity and feasibility of the modified hand-assisted retroperitoneoscopic laparoscopic nephrectomy (MHARLN) in patients with benign inflammatory non-functioning kidney diseases.MethodsWe retrospectively compared the data of 223 patients who underwent an MHARLN (n=142) or an open nephrectomy (ON) (n=81) with benign inflammatory non-functioning diseases between January 2014 and October 2019 at our hospital. Patients’ demographic data, perioperative outcomes, preoperative and postoperative inflammatory data, and postoperative complications were reviewed.ResultsThe basic demographic data of patients were similar between the 2 groups. The mean operative times for the MHARLN and the ON were 135 and 143 minutes (P=0.181), respectively. The first time at which postoperative ambulation occurred, the visual analog pain scale (VAS) score before discharge and the postoperative complication rate were similar in both groups. However, compared to the MHARLN, the ON was associated with a more severe inflammatory response on the first day after surgery (P=0.045), higher estimated blood loss (309.8 vs. 139.6 mL; P=0.036), more peritoneal ruptures (19.8% vs. 9.2%; P=0.024), higher intraoperative transfusion (14.82% vs. 4.93%; P=0.011), higher VAS scores 24 hours after surgery (5.9 vs. 5.2; P=0.002), additional analgesic use (35.8% vs. 21.8%; P=0.024), and longer hospital stays (5.3 vs. 4.6 days; P=0.048). Before a liquid diet was commenced in the MHARLN and ON groups, the mean time was 1.2 and 1.5 days, respectively (P=0.004).ConclusionsWhen performed by a skilled laparoscopic surgeon, the use of the MHARLN in patients with benign inflammatory non-functioning kidney diseases is reliable and safe. The MHARLN may help to treat challenging cases and result in less trauma successfully.
