Abstract

Condylomata acuminata (CA) caused by human papillomavirus, often involves the external genitalia, perianal skin, and other moist mucous membranes. Urethral involvement is uncommon and little recognized, and usually limited to the distal 3 cm of the meatus. It is difficult to treat CA involving the urethra because of the anatomical location, risk of complications and recurrence. One effective method for the treatment of CA located at the urinary meatus is 5-aminolevulinic acid photodynamic therapy (ALA-PDT). However, experience of using this method for the treatment of whole urethral CA is still very limited. Herein, we treated a whole urethral CA successfully with photodynamic and holmium laser therapies. The case of a 25-year-old patient who underwent kidney transplant effected by intraurethral CA is presented and discussed. Catheter implantation and (or) immunosuppression treatment increases the risk of urethral condyloma acuminatum. The ALA-PDT is a safe, straightforward, effective, and well-tolerated treatment procedure for intraurethral CA. ALA-PDT combined with holmium laser treatment can successfully treat kidney transplant patients with intraurethral CA.
