Transurethral microwave thermotherapy: symptom relief v urodynamic changes

Transurethral microwave thermotherapy (TUMT), whether in its low- or high-energy form, seems to reduce the symptoms of benign prostatic hyperplasia, with low-energy treatment resulting in less improvement than high-energy treatment. Low-energy TUMT has a minimal effect on bladder outlet obstruction, as judged by urodynamic findings, and may not be suitable to treat those patients with significant obstruction. High-energy TUMT does seem to relieve obstruction significantly, although it is not as effective as TURP. Urodynamic studies may provide the answer as to which therapy to offer the patient.
