[Symptoms and development of Schistosoma haematobium infestation seen in a metropolis].

Urogenital schistosomiasis is often diagnosed in France where, contrary to its severity, its initial presentation (mainly haematuria) has not changed. The frequency of major renal abnormalities seems to have diminished since 1965, but above all cystoscopy and intravenous urography have been superseded by ultrasonography, a totally harmless and painless method which provides the same information as that obtained with the previous two methods, except as regards the ureters. In particular, cystoscopy is now indicated only when tumours of the bladder are suspected at ultrasonography. Cutaneous schistosomiasis, with its characteristic features, deserves to be known and recognized.
