Abstract

A new technique of nephrolithotomy was used to remove calyceal stone in seven cases. Key points of this technique are direct removal of stone through the calicopuncture by forceps without renal vascular clamping and Gelfoam Packing followed by compression with hands for control of bleeding. The results were s follow : 1. With the exception of a single small stone all the targeted calculi were removed (94% in completeness of stone removal). 2. This method did not have any significant renal parenchymal damage and there was no episode of postoperative urine leakage of delayed bleeding. 3. Postoperative complications were a case of urinary obstruction caused by slipped Gelfoam into calyx accidently, which was delivered spontaneously during the voiding on 2nd postoperative day and a case of wound infection. This new technique nephrolithotomy was seemed to be an useful and rapid surgical method of calyceal stone surgery in some situations such as in case of marked adhesion present around the pelvis, narrow infundibulum and failed stone removal during the performing pyelolithotomy.
