The patient presented to the emergency department with hematuria of several days' duration.

Patient Data

Age: 20 years
Gender: Male

Urinary bladder is moderately replete with diffuse thickening of the wall, with some nodular components, up to 10-12 mm thick. No Doppler signal is associated.

Kidneys of normal size and morphology, with preserved cortical thickness and adequate corticomedullary differentiation.

There are no signs of lithiasis, and there is no evidence of dilatation of the urinary excretory system.

No free intra-abdominal fluid was observed.

Case Discussion

Findings on ultrasound suggested a probable infectious origin, to be further assessed for schistosomiasis given the patient's context.

The diagnosis of urinary schistosomiasis was subsequently confirmed through the identification of Schistosoma eggs in urine following exercise.
