Long-term outcomes of laparoscopic versus open donor nephrectomy for kidney transplantation: a meta-analysis.

Laparoscopic surgery is widely used for living donor nephrectomy and has demonstrated superiority over open surgery by improving several outcomes, such as length of hospital stay and morphine requirements. The purpose of the present study was to compare the long-term outcomes of open donor nephrectomy (ODN) versus laparoscopic donor nephrectomy (LDN) using meta-analytical techniques. The Web of Science, PubMed and Cochrane Library databases were searched, for relevant articles published between 1980 and January 20, 2020. Lists of reference articles retrieved in primary searches were manually screened for potentially eligible studies. Outcome parameters were explored using Review Manager version 5.3. The evaluated outcomes included donor serum creatinine levels, incidence of hypertension or proteinuria at 1 year postoperative, donor health-related quality of life, donation attitude, and graft survival. Thirteen of the 111 articles fulfilled the inclusion criteria. The LDN group demonstrated similar 1 year outcomes compared with ODN with respect to serum creatinine levels (weighted mean difference [WMD] -0.02 mg/dL [95% confidence interval (CI) -0.18-0.13]; =0.77); hypertension (odds ratio [OR] 1.21 [95% CI 0.48-3.08]; =0.68); proteinuria (OR 0.28 [95% CI 0.02-3.11]; =0.30); and donation attitude (OR 4.26 [95% CI 0.06-298.27]; =0.50). Donor health-related quality of life and recipient graft survival were also not significantly different between the groups analyzed. Thus, the long-term outcomes between LDN and ODN for living donor kidney transplantation are similar.
