[Urinary retention with ruptured fornix caused by a maggot. An autoerotic accident]. / Harnstauung mit Fornixruptur durch Schmeissfliegenlarve Ein autoerotischer Unfall.

Foreign bodies in the urinary tract represent a possible cause for genitourinary disease. A huge variety of objects are inserted into the urinary tract for therapeutic, autoerotic, or psychiatric reasons and the symptoms for foreign bodies can be rather unspecific. Dysuria, hematuria, and urinary tract infection can suggest the presence of intravesical foreign bodies. Symptomatic urinary retention is more seldom and the causal foreign bodies are mostly iatrogenically applied. We present a unique case of maggots self-inserted into the urinary tract for autoerotic reasons causing symptomatic urinary retention with fornix rupture.
