[Interstitial laser coagulation in the treatment of benign prostatic hyperplasia. Preliminary results]. / Interstitiell laserkoagulasjon ved behandling av benign prostatahyperplasi. Preliminaere erfaringer.

ABSTRACT

51 patients aged 68 (range 52-81) years with lower urinary tract symptoms compatible with obstruction from benign prostatic hyperplasia were treated with interstitial laser coagulation (ILC). Postoperative urinary retention lasting less than one week was seen in the majority of cases. All patients were followed up for three months and ten cases had further follow-up after one year. Three months after treatment the international prostate symptom score decreased from 23.3 +/- 0.7 to 8.9 +/- 0.8 and was 10.2 +/- 2.1 after one year. Peak urinary flow increased concomitantly from 8.3 +/- 0.4 to 12.2 +/- 0.7 at three months and was 11.5 +/- 1.4 ml/sec after one year. Three patients received other, additional treatment because the ILC-treatment failed. In conclusion, interstitial laser coagulation had marked effects on symptoms, whereas the effects on objective parameters were less pronounced in this selected group of patients. However, more extensive follow-up, is essential for further evaluation of this new treatment procedure.
