BP surges occur in many men undergoing transurethral microwave therapy (TUMT) for BPH, according to researchers at the Mayo Clinic in Rochester, Minn.

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).
