BP surges occur in many men undergoing transurethral microwave therapy (TUMT) for BPH, according to researchers at the Mayo Clinic in Rochester, Minn.
They retrospectively studied 185 patients who received TUMT. Of these patients, 77 (42%) had an increase in systolic BP of more than 30 mm Hg during the procedure. Thirty patients (16%) had an increase of more than 50 mm Hg, and 10 (5%) had an increase of more than 70 mm Hg.
The researchers observed a greater than 20% change in systolic BP from baseline in 95 patients (51%).
“These BP changes represent a potential risk of cardiovascular events in patients with known or occult cardiovascular disease,” the authors wrote in Mayo Clinic Proceedings (2008;83:309-312).
