[Hematuria in Schistosoma mansoni bilharziosis].

Following a stay of a few months in Africa, a 9 year old boy developed gross hematuria, dysuria and pollakisuria. Two urine cultures remained sterile, the intravenous urography was normal. Therefore a tropical disease was looked for. Eggs of Schistosoma mansoni in the urine sediment, a significant level of schistosomal antibodies, and blood eosinophilia proved our suspected diagnosis of schistosomiasis to be correct. An ultrasonic examination of the urinary tract showed a thickened bladder wall. Very unusual in this case is the primary infection of the bladder with Schistosoma mansoni which normally affects the intestine.
