[Percutaneous nephrolithotomy of an upper pole calix stone in a transplanted kidney].

INTRODUCTION

Nephrolithiasis in a transplanted kidney is an uncommon complication and may lead to an acute deterioration in renal function. Different techniques for stone treatment are known. In this case, we were successful by using percutaneous nephrolithotomy for the removal of the stone.

CASE REPORT

A 65-year-old male patient was found with urinary retention II degrees two months after renal transplantation. A stone in the upper pole calix was found as the probable cause. Percutaneous nephrolithotomy with a 15-Charr Storz mininephroscope was used successfully to disintegrate and remove the stone.

CONCLUSION

In comparison to other techniques for the removal of stones, percutaneous nephrolithotomy is a secure method in the treatment of nephrolithiasis in a transplanted kidney. This technique treats the renal stone in one session. We used a 15-Charr Storz mininephroscope which is less invasive than the usually used nephroscopes with a bigger lumen.
