الملخص EN

To evaluate the ultrasound findings of urinary schistosomiasis in Quran school (Khalwas) children in Gezira State Sudan, we studied all the students from two schools.

A total of 103 boys were tested for urinary schistosomiasis using the urine filtration method.

Schistosoma haematobium (S.

haematobium) eggs were counted.

Ultrasound was performed for all the positive subjects.

Seventy-three (71 %) subjects were positive for S.

haematobium.

The mean age was 11.3 ± 2.9 years.

Sixty-six (90.4 %) subjects showed urinary tract abnormalities.

The findings revealed the following degrees of wall thickening : 53.0 % mild, 18.2 % moderate and 21.2 % severe.

Urinary bladder polyp(s) were noted in 43.3 % (single) and 40.9 % (multiple) of the subjects, and calcification of the bladder wall was observed in 7.6 % subjects.

Ureteric dilatation was noted in 38 / 73 (52.0 %), while hydronephrosis was detected in 19 / 73 (26.3 %).

The vast majority of urinary tract schistomiasis lesions were in the urinary bladder.

Ultrasound is a useful tool for identifying the morbidity of S.

haematobium in endemic areas.
