Health-related quality of life after retroperitoneoscopic and hand-assisted laparoscopic nephrectomy

The assessment of postoperative recovery typically involves the use of measures that are open to bias. Whilst there has been some work done on the short-term postoperative recovery comparison for hand-assisted laparoscopic nephrectomy (HALN) and retroperitoneoscopic nephrectomy (RPN), to our knowledge, this is the first study to look at long-term health outcomes for these two procedures. This study sought objectively to compare long-term postoperative health-related quality of life (HRQoL) after retroperitoneoscopic and hand-assisted transperitoneal laparoscopic nephrectomy undertaken for renal pathology. This was achieved by both reviewing perioperative data from medical records and by using the SF-36 questionnaire postoperatively.

Patients who had undergone elective retroperitoneoscopic (N = 19) or transperitoneal HALN (N = 32) between 2001 and 2004 at our institution underwent objective HRQoL assessment via a validated telephone questionnaire (SF-36) and by review of postoperative data from the medical records. This survey was administered between 3 and 6 months after surgery. The data then underwent statistical analysis using the paired Student's t-test.

Perioperative data showed no significant difference in the postoperative complication rate in the two groups. The HRQoL scores gathered from the SF-36 questionnaire gave mean scores of 67.4 and 68.5 for the HALN and RPN groups, respectively (100 represents maximum quality of life). This difference was not statistically significant.

This is the first study to look at long-term (mean follow-up 6 months) health outcomes for patients undergoing RPN and HALN. The results show no greater long-term health benefit for one procedure over the other. This finding supports the data in the literature on the benefits of HALN over RPN in terms of a less protracted learning curve, greater technical ease, fewer intraoperative complications, and consequently reduced operating times with no loss of the long-term health benefit that is traditionally associated with the standard laparoscopic technique.
