Self-Inflicted Foreign Bodies in the Lower Urinary Tract Associated with Sexual Activities—A Case Series

Foreign bodies in urological patients are commonly found in the lower urinary tract, especially in the bladder and urethra. Items such as pens, pencils, wires, and cables are often inserted for erotic stimulation, typically associated with alcohol intoxication or psychiatric disorders. The aim of this study is to present the adverse events of non-conventional sexual manipulation and the harmful effects of using atypical objects for masturbation purposes. The study presents a series of case reports describing patients with self-inflicted foreign bodies in the lower urinary tract, collected over 20 years at a single medical center. Most patients were admitted to the hospital with lower urinary tract symptoms (LUTSs) and signs of infection, such as abdominal pain and fever. Only 6 out of 12 patients revealed their intention regarding foreign body insertion. Additionally, 9 out of 12 patients did not attend the follow-up visit. Self-inflicted foreign bodies in the lower urinary tract vary in type and motive. Patients may be reluctant to disclose these circumstances, complicating diagnosis and treatment, which can lead to serious health risks and a reduced quality of life.
