[A western cohort of urinary schistosomiasis]

Urinary schistosomiasis is very frequent, but there are few data upon its epidemiology in western countries. We wanted to describe the cohort from Tenon hospital, in Paris, France, near a big subsaharian community.

Methods: We searched in our clinical files database for "urinary schistosomiasis" encoding.

Results: The cohort comprised 207 men and 34 women seen for the first time at the mean age of 34, mainly for haematuria or LUTS. Patients were mainly native from subsaharian Africa. The lost to follow up rate was 54%. Diagnosis was made on sole endoscopic finding in half of the cases. For non-tumor pathology, were made seven cystoplasties et 12 ureteral dilations. Tumoral pathology was frequent and severe (15/81 from the same age range), mainly represented by urothelial histology (8/14). Imported cases were rare (five cases).

Conclusion: Despite its limitations, different characteristics from this cohort seemed noticeable: frequency of sole lower urinary tract symptoms, frequency and severity of tumoral diseases, mainly with urothelial carcinoma as histology.
