[Three patients with indinavir-related urolithiasis].
Three HIV-seropositive patients were diagnosed with urolithiasis related to the use of indinavir. The first patient was a 45-year-old white male with severe haemophilia who presented with fever and flank pain referred to the glans penis. Ultrasound and intravenous pyelography (IVP) revealed a concrement in the left renal pelvis. Discontinuation of indinavir and acidification of the urine did not reduce the stone load. Percutaneous nephrolithotripsy was then performed. The second patient, a 41-year-old white male, presented at the emergency ward with flank pain and fever. Ultrasound examination showed dilatation of the left kidney. A percutaneous nephrostomy catheter was inserted. Antegrade contrast imaging showed a concrement in the proximal ureter. The patient underwent extracorporeal shock wave lithotripsy. A second antegrade image made a few days later showed no evidence of stone material. The third patient was a 56-year-old white male with a previous history of indinavir-associated urolithiasis. He presented at the emergency ward with flank pain and haematuria. A CT urography showed dilatation of the right kidney and distal portion of the right ureter with no evidence of concrement. The symptoms resolved after a percutaneous nephrostomy catheter was inserted and the antiviral medication was modified. The catheter was removed 2 weeks later. At last follow-up, none ofthe 3 patients had symptoms of urolithiasis. These cases illustrate that, although conservative therapy for indinavir-related urolithiasis can be sufficient, minimally invasive endourological surgery is sometimes necessary.
