Schistosoma haematobium causes urinary schistosomiasis.In chronic cases, bladder carcinoma can occur, and bladder calcification can result in extensive fibrosis that causes the bladder to lose contractility.1 S. haematobium can be found in semen samples in 43% of affected men indicating a genitourinary clinical presentation.1,2 Bladder cancer is the most common cancer in men living in Egypt and may be related to the prevalence of long-term S. haematobium infections.1 From 1994 through 1996, 16% of bladder cancers in the Egyptian population were associated with chronic S. haematobium infection.2 3.Schistosoma mansoni and Schistosoma japonicum cause intestinal and hepatic schistosomiasis;3 S. haematobium results in urinary schistosomiasis.

Schistosoma haematobium causes urinary
schistosomiasis. Urinary schistosomiasis can range
from asymptomatic, in cases of low worm burden, to
gross hematuria and obstructive uropathy in heavy
worm burden. In chronic cases, bladder carcinoma can
occur, and bladder calcification can result in extensive
fibrosis that causes the bladder to lose contractility.1
S. haematobium can be found in semen samples in
43% of affected men indicating a genitourinary clinical
presentation.1,2 Bladder cancer is the most common
cancer in men living in Egypt and may be related to the
prevalence of long-term S. haematobium infections.1
From 1994 through 1996, 16% of bladder cancers in the
Egyptian population were associated with chronic S.
haematobium infection.2
3. Schistosomiasis is caused by blood flukes of the
genus Schistosoma. This condition affects nearly 200
million people worldwide3
and is ranked as the second
most common cause of serious morbidity and mortality
worldwide, resulting in approximately 800,000 deaths
per year.4
Also called bilharziasis, these diseases are
caused by 3 main species within this genus. Schistosoma
mansoni and Schistosoma japonicum cause intestinal
and hepatic schistosomiasis;3 S. haematobium results in
urinary schistosomiasis. All schistosomes are transmitted
by contact with bodies of fresh water that are home to the
intermediate host of the schistosome, which are snails in
the genera Biomphalaria and Oncomelania (S. mansoni
and S. japonicum) and Bulinus (S. haematobium)
