Percutaneous Nephrolithotomy: Experience with 200 Cases / 대한비뇨기과학회지

ABSTRACT

In 200 patients with renal stone and upper and midureter stone, we have tried 241 sessions of percutaneous nephrolithotripsy. The success rate of nephrolithotripsy for different location and type was as follows. For renal pelvis stone 96.5%, staghorn stone lOO%, calyceal stone 84.4%, UPJ and upper ureter stone 76.8%, midureter stone 66.7%. We were successful in most of cases after preliminary report of earlier experience with 50 cases. And improvement of the result in removal of calyceal stone and upper ureter stone was especially conspicuous. In addition, we have complied experience with percutaneous removal of stone in patient with solitary kidney and of staghorn stone, and the result was satisfactory. Based on the accumulated experience, it was possible to remove almost all renal stones and most of upper and midureter stones by percutaneous approach although residual stones were present in large pelvis stone and staghorn stone. Thus in future, even when ESWL is widely utilized, endourologic management must be included in the algorithm of treatment of stone diseases to expect better success rate and less complications.
