Transurethral resection of the prostate (TURP) has been the gold standard for the treatment of symptomatic benign prostatic hyperplasia for three decades but is now being challenged by other approaches such as transurethral microwave thermotherapy (TUMT). Comparison of these techniques must consider the functional, financial, and social aspects of each procedure. Because of differences in equipment, it is difficult to draw valid conclusions from the comparisons of the functional results of TURP v TUMT, but the two appear equivalent in relieving symptoms, although TUMT appears slightly less effective in improving flow. Preliminary data suggest that TUMT is less expensive than TURP, but more data are needed. Although high-energy TUMT is not yet on a par with TURP, it is a valid alternative for many patients.
