Assessing the impact of renal artery clamping during laparoscopic partial nephrectomy (LPN) for small renal masses: the rationale and design of the CLamp vs Off Clamp Kidney during LPN (CLOCK II) randomised phase III trial
Interplay between patient‐ and surgery‐related factors determines the functional recovery after partial nephrectomy (PN) 1. Ischaemic injury resulting from renal arterial clamping has historically been one of the major modifiable surgical factors responsible for the functional decline after PN. As such, several techniques for minimising or even eliminating hilar clamping have been described 2.
