TUMT is the most frequent minimally invasive treatment used worldwide.
But while TUMT generally has fewer serious side effects than surgery, a recent study suggests it's not without risks.
The study, published in March in Mayo Clinic Proceedings, found that many men undergoing TUMT experience dangerous spikes in blood pressure during the procedure.
TUMT uses microwave energy delivered by a catheter fed through the urethra to destroy prostate tissue and relieve BPH symptoms.
With >100,000 procedures performed, TUMT is the most frequent minimally invasive treatment utilized worldwide.
TUMT is well-suited to high-risk patients or those who oppose surgery
TUMT relieves urinary obstruction because the BPH tissue is heated to 113 to 130|degrees~F, while the thermally nociceptive urethral mucosa is kept at |is less than or equal to~ 112|degrees~F (|is less than or equal to~ 44.5|degrees~C) by conductive cooling, shown in Figure 4b.
The transurethral route of energy administration was chosen for TUMT because benign prostatic hyperplasia develops only in a limited region around the proximal urethral segment of prostate.
Hofner, Tubaro, de la Rosette, and Carter (1998) compared the predictive power of the A-G, linPURR (Schafer), and CHESS nomograms in determining objective and symptomatic response to TUMT in a group of 97 men diagnosed with BPH.
TUMT is a reasonable treatment consideration for the patient who has moderate symptoms, small to moderate gland size and a desire to avoid more invasive therapy for potentially less effective results.[sup.64] TUMT may be associated with a higher re-treatment rate over a 5-year follow-up interval than for men receiving TURP.[sup.64,65] TUMT is not an insurable service anywhere in Canada at this time; patients are required to pay for this procedure.
A randomized study comparing high-energy TUMT to TURP: quality-of-life results.
Minimally invasive surgical therapies procedures include transurethral microwave treatment (TUMT), transurethral needle ablation and laser prostatectomy.
