Parachordodes sp. (Nematomorpha) human infestation of the lower urinary tract: The first case report in China

Abstract

A living worm was discharged per urethram of a 26-year-old woman, and identified as Parachordodes sp. based on its morphologic characteristics. This is the sixth case of human urinary infestation with nematomorphs ever reported in the world literature. Her case history, symptoms, treatment were recorded. The morphology of this worm was observed in detail. The route of the invasion of nematomorph was also discussed. It is suggested that the human urinary infestation occurred when the lower body of the patient was immersed into natural waters, such as swamps, ponds, spring-pools, ditches, streams, etc., with the larva or small immature worm entering the urethra, especially of a female patient, and going further into the bladder.
