Interstitial laser therapy outcomes in benign prostatic hyperplasia.
Two hundred thirty-nine patients with benign prostatic hyperplasia (BPH) were treated using interstitial laser coagulation (ILC or LITT; laser-induced interstitial thermotherapy), and the long-term results were determined. In this minimally invasive procedure, special laser light guides were inserted into the adenoma tissue in order to achieve primary large-volume coagulation necrosis and secondary shrinking, leaving the urethra intact. The AUA Symptom Scores improved markedly, from an average of 25 pretreatment to an average of 6 at 1 year. Peak urine flow rates improved commensurably, from 8 mL/sec pretreatment to 18 mL/sec at 1 year. Postoperative irritative symptoms occurred occasionally, affecting only 12% of patients. Significant complications were rare, with 4% of patients suffering strictures and 7% retrograde ejaculation. No patients suffered impotence or incontinence. Only 9.6% of patients required retreatment for BPH during 12 months of follow-up. Twelve patients were treated with subsequent transurethral laser incision of the bladder neck in order to shorten the time required for improvement of voiding function.
