Initial Experience of Percutaneous Removal of Upper Ureteral Stone / 대한비뇨기과학회지

We tried percutaneous extraction of upper ureteral stones in five patients via Wolf rigid ureteroscope with grasping forceps. The procedure was performed at two session. The nephrostomy tract dilation was carried out by combination of metal dilator and Amplatz teflon renal dilator under fluoroscopy. All the five cases of PCN were successful without any complication at first trial. The advantage of this technique is low postoperative morbidity, rapid convalescence, sooner return to work and cheap price. It seems that endourological treatment of mid ureteral stone as well and upper ureteral stone can be extracted through percutaneous nephrostomy tract.
