title: Kidney Laterality and the Safety of Hand-assisted Live Donor Nephrectomy: Review of 1000 Consecutive Cases at a Single Center.
abstract: OBJECTIVE
  To determine the feasibility of performing right-sided, hand-assisted, laparoscopic donor nephrectomy (HALDN) and compare with the results of left-sided surgeries in both donors and recipients.
  
  
  METHODS
  Between September 2006 and September 2013, 1000 consecutive patients underwent HALDN at our institution. Patient characteristics and the intraoperative or postoperative parameters of the donors and recipients were retrospectively evaluated. Preoperative data, including relative renal function, vascular anatomy, and parenchymal abnormalities, were evaluated to determine the reasons for harvesting the right kidney. Intraoperative and postoperative data, including pneumoperitoneum time, warm ischemia time, complications, chronic kidney disease stage, and graft function, were compared between donors and recipients who underwent right- and left-sided procurement.
  
  
  RESULTS
  Mean follow-up period was 21 months in donor and 42 months in recipient. Right-sided HALDN was performed on 421 patients (42.1%). The most common reasons for selecting the right kidney was reduced right kidney function (53.4%) followed by multiple left renal arteries (34.2%). None of 1000 patients required conversion to open surgery or developed major complications. Serum creatinine concentrations and chronic kidney disease stage at the last follow-up examinations were similar in donors. There were no significant differences in graft function and ureter-related complications between right- and left-sided kidneys at the last follow-up examination.
  
  
  CONCLUSIONS
  Right-side HALDN is a safe procedure. The donor side can be freely selected using HALDN to benefit both donors and recipients.
