Abstract

Interstitial laser coagulation of the prostate was performed on 28 patients with BPH symptoms aged in the range 51 to 86. The operation was performed under i.v. anesthesia from 2-8 positions with the maximum radiation power 10 W in a programmed mode. Remote results of the treatment were evaluated at 12. months postoperatively by IPSS, uroflowmetry, and transrectal ultrasound. Results Preoperatively the patients were evaluated as follows: IPSS - from 19 to 26, peak urine flow rate - 6.7±2.1 ml/s (from 3 to 9), residual urine 98.1±19.2 ml (from 85 to 300 ml), prostate volume- 48.1±8.9 cc (from 31.6 to 69.2). At 12 months postoperatively 25 patients of 28 (89.3%) were on the whole satisfied with the quality of their voiding, which was reflected by the IPSS follow-up values from 10 to 16. The mean peak urine flow rate was 16.2±1.4 ml/s, the residual urine was 30.4±8.7 ml (from 0 to 50). The prostate volume varied with patients in the group: from a significant reduction to a moderate increase against the background, the amplitude of variation being 30 to 58 cc (mean value 34.9±5.44 cc). In 3 cases of 28 (20.1%) the increase in obstructive symptoms required subsequent surgical intervention: transvesical prostatectomy - 1, repeat interstitial laser coagulation -1, TURP - 1. Conclusions: Our experience of a long-term follow-up of patients subjected to interstitial laser coagulation of the prostate for obstructive BPH shows that this technique is an efficient means to resolve infravesical obstructions, with a long-lasting effect.
