Abstract

Developing the instruments in urological field, the urinary tract stones may be manipulated more easily and lesser invasively recently. The percutaneous nephrolithotripsy is one of the most widely using technique for the renal stone. But, the major portion of the failure through the manipulation of percutaneous nephrolithotripsy is the access to the correct, wanted calyx by puncture. So, we observed the 27 normal right kidneys and 26 left kidneys by abdominal computer tomogram scanning and excretory urography for the Korean caliceal anatomy. The following results were obtained 1. The average values of posterior renal rotation from the coronal plane of body were 31.0 degrees +/- 4.4 degrees in the right kidneys 32.4 degrees +/- 3.2 degrees in the left kidneys. 2. The average values of anterior and posterior caliceal angle were 58.8 degrees +/- 7.6 degrees and 20.7 degrees +/- 5.8 degrees in the right kidneys; 38.3 degrees +/- 6.2 degrees and 43.0 degrees +/- 5.2 degrees in the left kidneys. 3. The major type of classical system was Brodel type (74.l%) in the right kidney; Hodson type (53.8%) in the left kidney. 4. The anterior calyx is more laterally placed about 8l.8% in the excretory urography.
