Abstract
Screening for Schistosoma haematobium infection and its possible morbidity was carried out in 257 adult participants in Eggua
community,Ogun State,Nigeria. Parasitological assessment for the presence of ova of S. haematobiumin urine and abdominopelvic
ultrasonographic examination for bladder and secondary kidney pathology were carried out. S. haematobiumprevalence of 25.68%
(66/257) was recorded among the participants. There was a significantly higher prevalence of 69.2% of urinary schistosomiasis in
the females than the prevalence of 31.8% inmales (𝑃 = 0.902). The intensity of infections was mostly light (55) (21.8%) compared to
heavy (10) (3.9%) with themean intensity of 16.7 eggs/10mL urine. Structural bladder pathology prevalence among participants was
33.9%. The bladder and kidney pathologies observed by ultrasound in subjects with S. haematobium infections included abnormal
bladder wall thickness (59%), abnormal bladder shape (15.2%), bladder wall irregularities (15.2%), bladder masses (1.5%), bladder
calcification (1.5%), and hydronephrosis (3%). Infection with S. haematobium was associated with bladder pathology. Higher
frequencies of bladder abnormalities were observed more in the participants with light intensity of S. haematobium infection than
in those with heavy infection. More bladder pathology was also seen in women than in men, although this was not statistically
significant. In conclusion, there is evidence that the development of bladder pathology may be associated with S. haematobium
infection.
