[Urinary schistosomiasis: report of a case].

A 20-year-old unmarried Ghanaian man complaining of macroscopic hematuria and cystitis symptom was admitted to our institute. Abdominal ultrasound revealed a hyper echoic lesion in the entire bladder wall. Computed tomography showed a calcification of the whole bladder wall and of the left lower ureter. Flexible cystoscopy revealed many nodular masses, so-called 'bilharzial tubercles', at the trigone and posterior wall of the urinary bladder, and there was partial bleeding. Pathological examination revealed granuloma with many calcified eggs of schistosome haematobium. He was diagnosed with Bilharzial schistosomiasis and was treated with 1,500 mg of praziquantel for two days. However the therapeutic effect was insufficient. Therefore, he was treated with 2,400 mg of praziquantel for two days, and the symptoms disappeared.
