Ureteral stent encrustation in an HIV patient treated with disposable flexible ureteroscope: a case report.

Human immunodeficiency virus prevalence was increasing worldwide. Medication-associated urinary calculi are very commonly caused by medications used to treat HIV-positive patients. We present a case of an HIV-positive 39-year-old male with ureteral stent encrustation and kidney stone. Ureterolithotripsy using a disposable flexible ureteroscope is performed. The postoperative evolution was favorable. The disposable flexible ureteroscope is effective in the treatment of HIV combined with ureteral stent encrustation.
