Vesical schistosomiasis with terminal hematuria in sub-Saharan patients

Abstract

Objectives: To know the characteristics of vesical schistosomiasis caused by schistosoma hematobium in immigrant patients.

Material and methods: The retrospective study of 41 cases microbiologically diagnosed in our hospital over the last 16 years is presented. Data was collected on origin, age, presentation form, diagnostic tests and treatment.

Results: All were African patients whose ages ranged from 4 to 32 years and who had terminal macroscopic hematuria. Most of the patients (85%) were men. In all of the cases, diagnosis was by a urinary microbiological study and in one case, cystoscopy with a biopsy of a typical vesical lesion. Terminal hematuria is the most representative clinical sign. They were treated with praziquantel.

Conclusions: The epidemiology and intermittent terminal hematuria in African patients should lead to the suspicion of vesical schistosomiasis as the first diagnostic option. Urinary microbiological study is a rapid, non-invasive, test with high diagnostic yield that would avoid performing invasive studies. Its simple treatment assures high level of compliance and consequent efficacy.
