Paper Abstract

The use of thermal energy in order to cause damage to obstructing prostate tissue is a recently introduced alternative to transurethral resection of the prostate (TUR-P). In order to assess the efficacy of perineal interstitial laser treatment, we report on 22 patients (operative high risk category), with a 6 month follow up, who have been treated with the Dornier ITT laser fiber. Treatment protocol designates the perineal approach for side lobe hypertrophy, transurethral approach for middle lobe hypertrophy, and the continuous application of decreasing increments of energy within specific time intervals. Results were evaluated by flow rate, residual urine, symptom score, reduction in prostate size, and cystomanometric studies. The overall success rate was 61%, flow rate improvement > 15 ml/sec in 50%, mean symptom score reduction from 26 to 7, residual urine decrease to < 50 ml within 12 weeks in 40%, and prostate volume decrease in 47%. Interstitial laser coagulation can be considered a safe alternative to TUR-P in a select number of patients, however a larger series of patients must be treated before the efficacy of the method is finally established.
