Is it possible to decrease the intrarenal pressure in the kidney during endoscopic management of kidney stone by topical administration of drugs? In order to secure fewer complications in ureteroscopic operations the pharmacological agent isoproterenol is tested on pigs and human to determine its potential of lowering intrarenal pressure.
