[Urological Comorbidities in an HIV-Infected Patient: A Case Report]

We report a case of a patient who developed several urological comorbidities associated with HIV infection. A 53-year-old male was diagnosed with HIV infection and AIDS. After 13 years, microhematuria was found and computed tomography (CT) revealed urolithiasis and a left renal tumor suspected of being renal cell carcinoma. Initially, he underwent transurethral lithotripsy. Stone analysis indicated that the stone was made of atazanavir. Then he received laparoscopic left partial nephrectomy. The pathological diagnosis was papillary type 2 renal cell carcinoma. Three years later, follow-up CT revealed a right renal pelvic tumor. Since right ureteroscopy showed that the tumor was papillary we diagnosed it as renal pelvic cancer and decided to perform laparoscopic right radical nephroureterectomy. His renal pelvic tumor was determined to be urothelial carcinoma by the pathological diagnosis. Intravesical recurrence occurred twice after the nephroureterectomy. His renal function gradually deteriorated during follow-up and we suspected that HIV nephrosis was one of the reasons for the deterioration. Hemodialysis was initiated at the age of 71.
