Abstract:
OBJECTIVE:To observe the effect of the three stages of 5-aminolevulinic acid-photodynamic therapy (ALA-PDT) on condyloma acuminatum of external urethral meatus.
METHODS:A total of 56 patients with condyloma acuminatum of external urethral meatus presenting at the Department of Dermatology of Xiangya Hospital from Janunary 2009 to September 2009 were randomly treated by the three stages of ALA-PDT. The topical ALA followed by PDT was carried out once a week for 3 weeks. Rates of cure, ineffectiveness, adverse effects and complications were observed. The follow-up time was 6 months and the recurrence rates were documented.
RESULTS:After treatment of three stages of ALA-PDT, complete remission was achieved in 48 out of the 56 patients (85.7%). The recurrence rate was 14.3% (8 cases), and 2 patients had no responses (3.6%). Only 1 patient had serious pain during the treatment, and the rate of adverse effect was 1.8%. No complications were observed.
CONCLUSION:The three stages of ALA-PDT are safe, effective and tolerant treatment for condyloma acuminatum of external urethral meatus.
