Transurethral needle ablation

From Wikipedia, the free encyclopedia

Transurethral needle ablation is a procedure that is used to treat benign prostatic hypertrophy (BPH). A small probe that gives off low-level radiofrequency energy is inserted through the urethra into the prostate. The energy from the probe heats and destroys the abnormal prostate tissue without damaging the urethra. Also called transurethral radiofrequency ablation.
