Effect of Papaverine on Renal Artery Blood Flow during Robot-Assisted Partial Nephrectomy: A Randomized Controlled Study.

Periarterial papaverine administration increased intraoperative renal artery blood flow and early postoperative GFR in RAPN, suggesting that papaverine administration has beneficial effects on renal perfusion after renal artery clamping and could be a valuable option for improving renal function after RAPN.
