    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; nephrology; Urologi; nefrologi; Urology; PET; Schelin Catheter; epinephrine; local anaesthetics; microwave thermotherapy; intraprostatic blood flow; PLFT; Benign Prostatic Hyperplasia; intraprostatic temperature; CoreTherm;

    Sammanfattning : Abstract: The purpose of this thesis was to evaluate ProstaLund Feedback Treatment® (PLFT®) and the CoreTherm® device with regard to biophysics, mechanisms of action, treatment indications, additional techniques, efficacy and safety in the treatment of patients with benign prostatic hyperplasia (BPH). The application of two biophysical equations in the PLFT software is explained. LÄS MER

  3. 2. Feedback thermotherapy for benign prostatic enlargement : A clinical and methodological evaluation

    Författare :Lennart Wagrell; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; benign prostatic hyperplasia; transurethral microwave thermotherapy; feed-back thermotherapy; intraprostatic blood-flow; intraprostatic temperature; bladderneck; PET; Kirurgi; Surgery; Kirurgi; kirurgi; särskilt urologi; Urology;

    Sammanfattning : The purpose of this thesis was to evaluate a new treatment strategy for symptomatic benign prostatic enlargement.The transurethral thermotherapy (TUMT) antenna design was studied. The design influences the heating-profile significantly and the absorbed energy in a target volume were only about 13-20% of the energy delivered. LÄS MER

  4. 3. Transurethral microwave thermotherapy of benign prostatic hyperplasia : a clinical and methodological evaluation

    Författare :Anders Hallin; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :benign prostatic hyperplasia; microwave thermotherapy; long-termfollow-up; MRI; semen; androgen.ISBN;

    Sammanfattning : Transurethral microwave thermotherapy (TUMT) is a relatively new type of treatment for symptomatic benign prostatic hyperplasia. The aim of this study was to evaluate different aspects of TUMT such as catheter characteristics, morphological changes, effects on hormones and semen emission as well as to assess long-term treatment outcome.

  5. 4. Transurethral microwave thermotherapy of benign prostatic hyperplasia : mechanisms of action and clinical outcome

    Författare :Marianne Brehmer; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :benign prostatic hyperplasia; transurethral microwave thermotherapy; clinical outcome; sham treatment; innervation; urethral sensitivity; necrosis; apoptosis; prostatic stromal cells in culture;

    Sammanfattning : Background: The therapeutic value of transurethral microwave thermotherapy (TUMT) in benign prostatic hyperplasia (BPH) is a matter of debate. Aims: Evaluation of the clinical effect of TUMT and of various duration of the treatment; investigation of the kind and extent of tissue lesions induced by TUMT and of the mechanisms behind the therapeutic effect; investigation of the effect of heat on human prostate stromal cells in cell culture.

    Sammanfattning : ABSTRACT Lower urinary tract symptoms (LUTS) are common among men and become more prevalent with increasing age. One frequent cause is benign prostatic obstruction (BPO). Patients with LUTS/BPO can be ameliorated if the obstructive tissue is removed. LÄS MER
