Interstitial Laser Coagulation for the Treatment of Benign Prostatic Hyperplasia: A 3 Year-Follow-Up of 30 Cases
Objective : To report the results and 3 year-follow-up of treatment of benign prostatic
hyperplasia (BPH) using interstitial laser coagulation.
Material and Method : Thirty men with BPH underwent treatment with interstitial laser
coagulation between December 1996 and April 1997. Their average age was 68 years old. All of
them were assessed prior to the treatment and post treatment for symptoms score, uroflowmetry
and postvoid residual urine. Any complication and consequence were evaluated at each follow-up
visit.
Results : Up to 36 months follow-up, all parameters showed marked improvement. The
symptom score decreased from 20 to 5. Peak flow rate increased from 4 ml/sec to 17 ml/sec. Resi-
dual urine decreased from 115 ml to 8 mi. No major complication was detected. Urethral catheter
or intermittent catheterization were used for the mean of 9 .l days. All of the patients who were
potent prior to the treatment remained potent and 75 per cent still had prograde ejaculation. No
re-treatment was needed in the 3 year-follow-up.
Conclusion : On the basis of these results, we propose that interstitial laser coagulation
appears to be a minimally invasive treatment for BPH, with substantial improvement of both
objective and subjective parameters.
