Gasless laparoendoscopic single-port clampless sutureless partial nephrectomy for peripheral renal tumors: perioperative outcomes.
Expert’s summary: Porpiglia et al compared functional outcomes between clampless laparoscopic partial nephrectomy (LPN) and conventional (warm ischemia) LPN using renal scintigraphy. Of the 87 patients analyzed in this study, 43 underwent conventional LPN and 43 underwent clampless LPN. At 3 mo after surgery, the percentage reduction in renal scintigraphy values was not significantly different between the groups, although a trend towards a greater reduction was observed in the conventional LPN group (split renal function –6% vs –5%, estimated renal plasmatic flow –17% vs –12% for conventional vs clampless LPN). Baseline renal function was the only predictor of postoperative renal function in the clampless group.
