Objectives: Long term data on the outcome of interstitial laser coagulation for the treatment of sub vesical obstruction due to benign prostatic enlargement have been rarely published. Our long-term outcome data are presented and the technique of interstitial laser coagulation is critically evaluated.

Methods: We carried out an evaluation of the outcome of consecutive interstitial laser coagulation procedures between 1999 and 2004. Follow-up was done by questionnaires sent to the outpatient urologists and by telephone interviews of patients.

Results: 68 patients were treated with ILC. Follow up was available for 66 patients (97%). Mean follow up was 41 months, 40 of 66 patients have been voiding spontaneously after ILC treatment (61%). Mean residual urine volume of these patients at the time of follow up was 25 ml (0-120 ml). Mean Qmax at the time of follow-up was 11.1 ± 4.5 ml/sec. 16 patients have needed a secondary procedure for bladder outlet obstruction (TURP in most of these) and have been catheter-free since that. 10 patients remained on catheter drainage. A history of high residual urine volume or urinary retention was identified as predictor for treatment failure.

Conclusion: Interstitial laser coagulation can be used in  selected patients
