Pan-urethral Wart Treated with 5-Fluorouracil Intraurethral Instillation

We evaluated whether or not intraurethral instillation of 5-fluorouracil (5-FU) solution can rapidly, safely, and effectively eradicate intraurethral condyloma acuminata in a human immunodeficiency virus (HIV) carrier. A 43-year-old man presented with the major complaint of difficult micturition and blood dribbling from the urethral meatus for more than 6 months. He was an HIV carrier for more than 10 years and had undergone diathermy for perianal warts. Physical examination showed cauliflower lesions over the orifice of the urethra and frenulum base of the penile prepuce. Urinalysis disclosed pyuria and microscopic hematuria. Cystourethroscopy on the following day showed extensive wart lesions extending from the urethra to the bladder neck. Biopsy of the lesions was compatible with condyloma acuminata. 5-FU solution (500 mg in normal saline 50 mL) urethral instillation with massage at the ventral side of the penile shaft for 20 minutes was given once a week for 7 doses. The urine routine was normal. Management was then prescribed once a month until the lesions became invisible under urethroscopy. After 18 doses of 5-FU solution urethral instillation, no visible wart lesions were noted. He has been asymptomatic with no voiding difficulty for more than 1 year.
