Fifty cases of kidney pelvic stone were admitted to the Department of Urology, Korea University Medical College during the period from Jan. 1968 to Dec. 1977 for the surgical removal of stone.
The age of patient ranged from 6 to 54 and 38 cases were male and 12 cases were female.
A new technique of pyelolithotomy was performed with incision made over the lower portion of renal pelvis as shown in Fig. 3 through the extraperitoneal subcostal arcuate anterolateral kidney approach with semilateral position and the following results were obtained.
1. In all fifty cases kidney pelvic stones were not spherical but flat in shape, and their removal were easily performed through the incision made over the lower portion of the renal pelvises.
2. Anatomically, very few distribution of the blood vessels were found in the lower area of the kidney pelvis and the manipulaotin -for removal of the stone was easier than that of other area of the kidney pelvis.
3. During-the manipulation of stone removal damages of the renal parenchyma or mucosal damages in the kidney pelvis if any could be kept at a. minimum.
4. When the kidney was exposed by extraperitoneal subcostal arcuate antero-lateral approach, the exposure of the lower portion of the hilum and the area of the kidney pelvis was easily made by mobilization and retraction of the kidney lower pole to the lateral side and this technique was found to be very convenient in removal of most kidney pelvic stones.
