The dissolution of multiple renal uric acid stones via percutaneous nephrostomy in the patient with a solitary kidney.

INTRODUCTION
The dissolution of urinary stones could be performed in the patients with urinary obstruction caused by phosphate, or uric acid stones, through the percutaneous nephrostomy (PCN).


CASE REPORT
A 27-year-old woman with complete obstruction of the solitary left kidney due to uric acid stones is presented. The woman was admitted in emergency unit due to anuria. Five days after PCN, irrigation with 1.6% sodium bicarbonate solution was initiated. Due to complete ureteral obstruction, the "Y" extension with the valve was connected to PCN and to the urinary bag, which enabled the patient to perform intermittent self-irrigation. After 12 days of irrigation, all the stones dissolute and ceased.


CONCLUSION
In the era of ESWL, PCNL and ureterorenoscopy, PCN-dissolution of urinary stones is rare procedure. However, this minimally invasive procedure could be successfully performed in selected cases.
