Transition from laparoscopic to retroperitoneoscopic approach for live donor nephrectomy
Laparoscopic donor nephrectomy has become the standard of care due to multiple benefits. Currently, there are various techniques employed with two different approaches: transperitoneal (TLDN) or retroperitoneoscopic (RLDN) approach. There is a lack of data to determine which technique is superior, although the RLDN offers an anatomical advantage by avoidance of manipulation of the intraperitoneal organs. The aims of this study were to explore the merits of RLDN to TLDN and assess the learning curve of transition from TLDN to RLDN.
From January 2010 to February 2017, 106 live donor nephrectomies were performed: 56 by TLDN and 50 by RLDN. Data on patient demographics, perioperative parameters, analgesic consumption, pain scores, and kidney graft function were collected and analysed. Data were compared with a Student’s t test or Mann–Whitney test. A CUSUM analysis was performed to investigate the learning curve.
All live donor nephrectomies were successful with no conversion to open surgery. There was no blood transfusion, readmission, or mortality. No postoperative complications were graded over Clavien II. Kidney function was comparable in both groups. The follow-up period ranged from 3 to 78 months.
Retroperitoneoscopic live donor nephrectomy is a safe approach with comparable results to TLDN. RLDN has an anatomical advantage as it avoids manipulating the intraperitoneal organs and retains a virgin abdomen and hence translates to a lower perioperative complication risk.
