[Long-term follow-up of interstitial laser coagulation in the treatment of benign prostatic hyperplasia].
BACKGROUND
Besides standard open or transurethreal adenoma resection, less morbid interstitial laser coagulation (ILC) is an alternative therapeutical option that could reduce lower urinary tract symptoms, especially in high-risk patients. Although short-term results indicate effectiveness, reliable long-term statistics are still lacking. Therefore, to assess long-term satisfaction and overall success rate, we re-evaluated patients with a mean follow-up of 7 years after laser treatment.


METHODS
A total of 72 patients had been included in our ILC programme between 1993 and 1995. Mean age was 74 years. About 45 % of the patients had since died of other causes. In all, 23 patients were evaluated by telephone questionnaire, International Prostate Symptom Score (IPSS), Quality of Life (QoL), second surgical interventions or medical therapy. Our patient group was treated with interstitial Nd:YAG laser coagulation (mediLas fibertom). A perineal (34 %), transurethral (23 %) or combined (43 %) approach was chosen, depending on the preoperative volume of the prostate (range 40 - 100 ml; mean 59.3 ml).


RESULTS
68.4 % of the patients were satisfied with their current urological situation. Mean IPSS was 8.8 vs. 18.8 preoperatively mean QoL 1.5 vs. 3.3. 15.8 % had undergone conventional transurethral prostatic resection in the interim; one patient uses a urine catheter. 15.8 % receive medical treatment for lower urinary tract symptoms.


CONCLUSIONS
Although the results of standard TUR or open surgery imply higher success, the long-term results of ILC demonstrate effectiveness. Further follow-up studies on a larger number of patients are advisable. The low morbidity of ILC makes this procedure an interesting alternative option in the treatment of high risk patients.
