Paris--Minimally invasive and surgical treatments for BPH are poorly studied and lack standardized techniques, said Jean de la Rosette, MD, of the department of urology, University of Amsterdam. Dr. de la Rosette chaired a committee on these rapidly expanding treatment approaches at the International Consultation on New Developments in Prostate Cancer and Prostate Diseases. Therapies considered by the committee included transurethral microwave thermotherapy, transurethral needle ablation, transurethral resection of the prostate, water-induced thermotherapy, transurethral ethanol ablation of the prostate (TEAP), prosthetic stents, and lasers.
