Comparison of ultrasonography, intravenous pyelography and cystoscopy in detection of urinary tract lesions due to Schistosoma haematobium.


The use of ultrasound in detecting urinary tract alterations by Schistosoma haematobium such as hydronephrosis and bladder calcifications was studied in 125 patients of the out-patients department of a district hospital in SE Tanzania, in an area highly endemic for this disease. Ultrasound was compared with plain abdominal X-ray (in 33 patients), intravenous pyelography (29), cystoscopy (31) and simple urine examination (125). Except for bladder calcifications which could not be demonstrated other than by X-ray, sonography compared favorably with IVP and cystoscopy and proved therefore to be a valuable tool in assessing S.h. related morbidity. In children moderate and advanced hydronephrosis were always associated with an irregular bladder wall and correlated strongly with the prevalence and intensity of S.h. infections as well as with haematuria and proteinuria. Important congestive pathology was observed in 1 out of 10 infected children and in 1 out of 20 examined adults.
