Nephrolithiasis and hydronephrosis in an HIV-infected man receiving tenofovir.

The use of tenofovir as part of a HAART regimen has been widely used in HIV-multi-experienced-patients because of its favourable resistance profile. Tenofovir is mainly eliminated by the kidneys and renal toxicity should be carefully monitored. We describe here the case of an HIV-infected patient, without a prior history of renal failure who developed nephrolithiasis and hydronephrosis after starting a tenofovir-containing HAART regimen.
