Urinary schistosomiasis: A 5-year clinical, radiological, and functional evaluation

Abstract
10 Egyptian male farmers with active S. haematobium infection were followed for approximately 5 years after effective antischistosomal treatment. In the absence of reinfection, persistent and continued renal improvement was noted. Indeed, lesions previously thought to have been irreversible, i.e. bladder calcification, were noted to have resolved. However, if patients became reinfected, marked urographic deterioration resulted. This study suggests that, at least for younger patients, reinfection with S. haematobium is likely in the highly endemic areas of Egypt, and that long-term follow up for the detection and treatment of reinfected patients is necessary to insure normal renal structure and function.
