[The therapeutic approach in vascular damage from pyelocaliceal endoscopic urology].

Six cases of vascular lesion associated with percutaneous removal of renal calculi are described. The lesions had been caused during percutaneous access or ultrasound fragmentation of the stone. Those that had resolved spontaneously have not been included. When vascular injury is suspected during the procedure, the appropriate measures must be taken to resolve the different complications, such as arteriovenous, arteriocaliceal or venocaliceal fistula. Since there is little reference to this subject in the Spanish literature, the experience described herein may be of interest to the urologist who has only recently begun to perform this technique.
