Abstract

During the last three years more than 350 patients have been referred to our department for Benign Prostatic Hyperplasia. In spite of a palpably normal prostate, with no evidence or suspect of neoplasm, all the patients were evaluated with the blood determination of prostatic specific antigen (PSA) and transrectal ultrasound of the prostate (TUSP). Multiple staging biopsies of the prostate and imaging techniques evidenced neither capsule infiltration nor metastatic disease. Because of the site of the tumor (nonperipherical zone) and its stage (T1 stage) in the latter 11 patients a transurethral resection of the prostate (TURP) followed by a laser irradiation was planned. In order to establish the tumor staging, a lymph node dissection (in the last year by laparoscopic lymphadenectomy) was carried out before the procedure. Six weeks after an enlarged TURP, a laser irradiation of the residual prostatic tissue was performed with a laser fiber inserted into a 21 Ch panendoscope. Using a power varying from 40 to 50 watts/4 sec, the whole surface of the remaining prostatic capsule was irradiated. After the treatment an indwelling catheter was left in place for 2-3 days and then the patient discharged from the hospital. There were no side effects. Potency and continence were preserved. Now with an average follow-up of 24 months, all patients have negative biopsies and no tumor progression.
