Abstract:
Objective To evaluate the effect of transurethral feedback microwave thermotherapy with the ProstaLund CoreTherm Device(PLFT) in high risk patients with benign prostate hyperplasia (BPH). Methods Sixty-six high risk patients diagnosed with BPH, including aged ≥80 in 32 pa-tients, hypertension in 31 patients, diabetes in 5 patients, heart failure in 8 patients, chronic obstruc-tive pulmonary disease in 8 patients, cerebral infarction in 11 patients, fracture, amputation or joint stiffness unsuitable for lithotomy position in 3 patients, abnormal blood coagulation in 4 patients, pan-creatitis in 2 patients, cardiac arrhythmia in 6 patients and malignant tumor in 3 patients, were treated with PLFT using individual power at urethral local anesthesia, resulting in coagulation necrosis in 15%-30% of prostate tissue around urethra. Meanwhile, real-time monitoring the temperature of prostate and the tissue around it was used. All patients were evaluated by comparing volume of pros-tate, maximal urinary flow (Q_max), international prostate symptom score (IPSS) and quality of life questionnaire (QOL) in pre-treatment and three months after respectively. Results All of patients well tolerated PLFT. There was bleeding lightly, infection lightly and temporary incontinence. There was no severe surgical complication. After three months, the volume of prostate reduced from 62. 2 ml to 44.5 ml; IPSS decreased from 23. 4 to 11.7; QOL decreased from 4.5 to 2.4; Q_max rised from 4, 2 ml/s to 11.2 ml/s. All differences reached significance. Conclusion PLFT is one of effective and safe treatments for patients with BPH especial BPH complicating with severe conditions.
