Urinary obstruction from sexual practice involving magnetized beads inserted in the male urethra

摘要

A 26-year-old man presented to clinic with a 3-day history of worsening dysuria and decreased urinary output; he had no additional systemic symptoms. He reluctantly disclosed that on the evening before the onset of symptoms, his girlfriend had inserted beads into his urethra as part of their sexual activity that night. The patient did not know the number or type of beads used. On physical examination, the patient was not in distress, his vital signs were normal, and his penis and abdomen were unremarkable. The results of urinalysis were normal. Urine culture was ordered, as were tests for chlamydia and gonorrhea. Because only distal urethral obstruction was considered based on the initial history, a radiograph of the penis was ordered; the radiograph showed no radio-opaque foreign bodies. The patient was discharged after being given antibiotic coverage for urinary tract infection, including possible chlamydia and gonorrhea infection, while awaiting test results. The patient was instructed to keep up with oral fluid intake and to return to the clinic the following day if there was no improvement.
