Percutaneous Nephrolithotomy: 52 Cases / 대한비뇨기과학회지

ABSTRACT

A percutaneous nephrostomy tract was used as a conduit to the kidney and upper ureter for extraction of calculi. We have performed percutaneous extraction of renal and upper ureter stones in 52 cases with the use of the percutaneous equipment and ultrasonic lithotrite. Overall success rate was 86.5% and average operating time was 90 minutes and mean hospitalization was 6.9 days. The advantage of this technique are that a skin incision of only 1 cm. is required to remove the stone, hospital days are fewer than with open procedures and postoperative morbidity is minimal. We conclude that percutaneous nephrolithotomy can be the primary choice of treatment in upper urinary tract stones.
