A novel technique to limit renal warm ischaemia time during laparoscopic partial nephrectomy.

Laparoscopic partial nephrectomy (LPN) is now accepted as a minimally invasive treatment option for small favourably located renal tumours [ 1 ] . Renal ischaemia is frequently necessary during both open PN (OPN) and LPN to facilitate tumour dissection and renal reconstruction in a bloodless fi eld. In OPN, this can often be achieved by manual compression, particularly for peripheral tumours. However, this is hard to replicate in the laparoscopic setting, and most surgeons rely on clamping the renal artery(ies) at the level of the hilum.
