Treatment of indinavir sulfate induced urolithiasis in HIV-positive patients.

Abstract

Indinavir sulfate is a protease inhibitor used of the treatment of primary HIV infection either as monotherapy or as part of antiretroviral treatment schemes. Approximately 10% of all patients develop urolithiasis with radiolucent stones consisting of indinavir. We present our results of the treatment in 11 HIV positive patients (9 men, 2 women), who developed Indinavir lithiasis after 5-8 months of antiretroviral therapy. Following the initial procedures (spasmoanalgetic drugs, ureteroscopy, double J-stent or nephrostomy), the patients were further treated by increasing diuresis and urinary acidification. All the patients responded well to the treatment, the obstruction was releieved and their renal function was restored to normal.
