View larger version (69K): [in this window] [in a new window]   An elderly man reported having recurrent hematuria over a period of two years. He had undergone transurethral resection of the prostate because of benign prostatic hypertrophy two years earlier. He had evidence of chronic renal insufficiency, with a serum creatinine level of 4.4 mg per deciliter (389 µmol per liter). Multiple urinalyses in the previous several months had revealed gross and microscopic hematuria, pyuria, triple phosphate crystals, and a pH of more than 9.0. For the previous two years, urinalyses had been intermittently positive for nitrates. Multiple urine cultures during the previous nine months had yielded only "contaminants." A computed tomographic scan of the pelvis appears here. What is the diagnosis? Editor's note: We invite our readers to submit their answers at www.nejm.org/mystery. We will publish the diagnosis in the Correspondence section of the March 30 issue and e-mail it to everyone who submits an answer. All answers must be received by February 16, 2006.
