The goal of laser coagulation (ILC) of prostate is to reduce the obstruction of lower urinary tract. The multiple application of laser energy into the prostatic interstitium creates focuses of coagulation necrosis in size from 2 to 2,5 cm, which undergo the further resorption, and finally cause the volume reduction of obstructing tissue. Authors provided interstitial laser coagulation using the Indigo 830e equipment in 30 patients, in 15 of them on an in-patient basis and in 15 of them on an out-patient basis. Procedures were provided under spinal or regional anesthesia. Statistical significant improvement of the symptomatic score IPSS (p<0,01), maximum flow (Qmax) (p<0,01) and postmicture residuum (p<0,01) were observed after surgery.
Average preoperative and postoperative values of IPSS were 20,3 and 7,1 resp., Qmax 8,9 ml/s and 14,6 ml/s resp., and the amount of residuum was 80 ml and 20 ml respectively. One patient underwent the transurethral prostatic resection for urine retention, another one had very low maximum flow documented by uroflowmetry after six months from procedure and two patients suffer from irritative symptoms resistant to anticholinergic treatment.
ILC is an effective alternative for treatment of benign prostatic hyperplasia and due to its low invasivity is beneficial namely for patients with increased internal risks.
