The treatment of 101 male patients with venereal warts is described. Prior to the study 33 patients had been treated unsuccessfully with podophyllin. 57 of the patients showed urethral lesions while 2 also showed venereal warts in the bladder. The primary treatment was electrocoagulation in 100 patients, 58 of these being cured. Chemical agents such as ethoglucid, Verruxin and thiotepa seemed to be effective in the treatment of resistant, especially intraurethral condylomas. In 8 patients autogenous vaccination was used, 6 responding completely to the vaccination alone while the remaining 2 were cured after vaccination and excision.
