Evaluation of renal function under controlled hypotension in zero ischemia robotic assisted partial nephrectomy.

Background/aims: In partial nephrectomy with hilar clamping every minute of ischemia can impair renal function, thus great importance is having the controlled hypotension as a part of zero ischemia technique. The aim of the study is to evaluate the effects of hypotensive anesthesia on renal function, in patients undergoing robotic assisted partial nephrectomy (RAPN) , during surgery and at 3 months follow up.

Methods: This is a prospective study of 100 patients, ASA 1-2, who underwent zero ischemia RAPN under controlled hypotension (CH) from December 2011 through to May 2013.
