Brief Summary:
during PCNL; A few milliliters of nor-epinephrine is injected into the intended tract after puncture of pelvicalyceal system and before its dilatation compared to injection of saline (placebo). hemoglobin change \& blood loss is estimated and will compared.
Detailed Description:
All patients of are positioned in lithotomy position and 6 F open tip ureteral catheter is fixed by cystoscope. Then, A pelvicalyceal system is punctured under ultrasound and/or fluoroscopic guidance, then a 18 Gauge (G) puncture needle is introduced toward the desired calyx and a 0.038 inch guide wire is inserted. then 20 G Chiba needle is introduced alongside the puncture needle for infiltration of the whole tract by either a few milliliters of nor-epinephrine or saline. then, the tract is dilated over the guide wire, lastly an Amplatz sheath was inserted.
