Genital bilharisiasis aetiology:
A. Causative organism: usually schistosoma hematobium.
B. Mode of infection: via communication between pelvic venous plexuses.
C. Predisposing factors: farmers.
Genital bilharisiasis pathology:
Sites: * Vulva & vagina: (the commonest sites to be affected).
* Uterus: very rare due to monthly shedding.
Deposition of ova in the submucosa:
* Sandy patches, bilharizial polyps, bilharizial ulcers & fibrosis.
Genital bilharisiasis diagnosis:
Symptoms:
– History of terminal hematuria.
– Vaginal discharge & bleeding.
– Infertility.
Signs:
– To detect sandy patches.
Investigations:
* Serology: to diagnose bilharisiasis (bilharizial antigens are the most reliable).
* Biopsy: from vulval & vaginal lesions.
Genital bilharisiasis treatment:
Medical: anti-bilharizial drugs e.g. Praziquantel.
Surgical: removal of residual lesions.

Dr. Claude Oeuvray speaks at ISNTD Coinfections 2016 about Male & Female Genital Schistosomiasis and Merck’s efforts at addressing this neglected gynaecological condition with significant implications for maternal & infant health, fertility and HIV infection risk.
Schistosomiasis (Bilharzia)– an overview video
Schistosomiasis is a tropical disease caused by a group of parasitic worms. It has an interesting life-cycle involving freshwater snails and can cause short term and long term disease. Schistosomiasis is classified as a neglected tropical disease and affects some of the poorest countries in the world. This video takes a look at the parasites, the disease that it causes and control methods.

Urogenital Schistosomiasis • Classical Sign – Haematuria • In women and children – lesions of the cervix and vagina – Nodules in the vulva – female genital schistosomiasis (FGS)
Organ affected Consequences Ovaries Hypogonadism, retarded puberty, infertility (primary and secondary) Fallopian tubes Ectopic/tubal pregnancy Uterus Anemia due to chronic blood loss, metaplasia, miscarriage, preterm delivery Cervix Anaemia, carcinoma, risk of STIs Vagina/Vulva Destruction of the hymen/clitoris, vesico-vaginal fistula, risk of STIs Consequences of FGS
