[Mixed urogenital schistosomiasis].

Urinary schistosomiasis is a parasitosis caused by Schistosoma Haematobium which affect in a diffuse manner all the genitourinary tract. Presentation of 5 patients (4 male, 1 female) with mixed Bilharziosis that was detected after the study of a young male that came to the clinic with a complaint of haematuria and who underwent transurethral resection under the suspicion of a vesical urothelial neoformation. Sch. Hameatobium eggs were detected in the urine and Sch. Mansoni in the semen of all 4 male. All of them evolved favourably with Praziquantel. Considering the rarity of schistosomiasis in our environment and its increased incidence in endemic areas, this process should be included in the algorithm of differential diagnosis in young patients reporting dysuric syndromes associated to haematuria; the relevance of an epidemiological anamnesis so as to institute early treatment and avoid the consequences of chronic infection is pointed out.
