Background. Selection of the right or left living donor kidney for transplantation is influenced by many variables. In the present multi centric study including 21 Italian transplant centres, we evaluated whether centre volume or surgical technique may influence the selection process. Methods. Intra- and perioperative donor data, donor kidney function, and recipient and graft survival were collected among 693 mini-invasive living donor nephrectomies performed from 2002 to 2014. Centre volume (LOW, 1-50 cases; HIGH,>50 cases) and surgical technique (FULL-LAP, full laparoscopic and robotic; HA-LAP, hand-assisted laparoscopy; MINI-OPEN, mini-lumbotomy) were correlated with selection of right or left donor kidney and with donor and recipient outcome. Results. HIGH-volume centres retrieved a higher rate of donor right kidneys (29.3% versus 17.6%, P<0.01) with single artery (83.1% versus 76.4%, P<0.05) compared with LOW-volume centres. Surgical technique correlated significantly with rate of donor right kidney and presence of multiple arteries: MINIOPEN (53% and 13%) versus HA-LAP (29% and 22%) versus FULL-LAP (11% and 23%), P<0.001 and P<0.05, respectively. All donors had an uneventful outcome; donor bleeding was more frequent in LOW-volume centres (4% versus 0.9%, P<0.05). Conclusions. Centre volume and surgical technique influenced donor kidney side selection. Donor nephrectomy in LOWvolume centres was associated with higher risk of donor bleeding.

Abstract

Background. Selection of the right or left living donor kidney for transplantation is influenced by many variables. In the present multi centric study including 21 Italian transplant centres, we evaluated whether centre volume or surgical technique may influence the selection process. Methods. Intra- and perioperative donor data, donor kidney function, and recipient and graft survival were collected among 693 mini-invasive living donor nephrectomies performed from 2002 to 2014. Centre volume (LOW, 1-50 cases; HIGH,>50 cases) and surgical technique (FULL-LAP, full laparoscopic and robotic; HA-LAP, hand-assisted laparoscopy; MINI-OPEN, mini-lumbotomy) were correlated with selection of right or left donor kidney and with donor and recipient outcome. Results. HIGH-volume centres retrieved a higher rate of donor right kidneys (29.3% versus 17.6%, P<0.01) with single artery (83.1% versus 76.4%, P<0.05) compared with LOW-volume centres. Surgical technique correlated significantly with rate of donor right kidney and presence of multiple arteries: MINIOPEN (53% and 13%) versus HA-LAP (29% and 22%) versus FULL-LAP (11% and 23%), P<0.001 and P<0.05, respectively. All donors had an uneventful outcome; donor bleeding was more frequent in LOW-volume centres (4% versus 0.9%, P<0.05). Conclusions. Centre volume and surgical technique influenced donor kidney side selection. Donor nephrectomy in LOWvolume centres was associated with higher risk of donor bleeding.
