The incidence of Filaria as an aetiological factor for testicular hydrocele.

Five hundred cases of hydrocele of the tunica vaginalis testis (TVT) have been studied in detail in order to ascertain their aetiology. In 43 per cent of cases hydrocele was found to be definitely due to filariasis, in 14 per cent it was highly likely that filariasis was responsible and in 16 per cent filariasis was suspected to be the aetiological factor. The remaining 27 per cent of cases were found to be non-filarial.
