Ultrasound findings in urogenital schistosomiasis: a pictorial essay

Urogenital schistosomiasis is a parasitic disease caused by S. haematobium which is endemic in tropical and sub-tropical areas but is increasingly diagnosed in temperate non-endemic countries due to migration and international travels. Early identification and treatment of the disease are fundamental to avoid associated severe sequelae such as bladder carcinoma, hydronephrosis leading to kidney failure and reproductive complications. Radiologic imaging, especially through ultrasound examination, has a fundamental role in the assessment of organ damage and follow-up after treatment. Imaging findings of urinary tract schistosomiasis are observed mainly in the ureters and bladder. The kidneys usually appear normal until a late stage of the disease.
