  1. 1. Urinary incontinence in middle-aged women - a population-based study on prevalence, risk factors and the role of the urethra

    Författare :Pia Teleman; Lund Obstetrik och gynekologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; reproduktion; sexualitet; gynaecology; andrology; reproduction; sexuality; Obstetrik; gynekologi; andrologi; Obstetrics; stress incontinence; urodynamic investigation; overactive bladder; population study; urethral sphincter; urethra; urinary incontinence; middle-aged women;

    Sammanfattning : Urinary incontinence classification is based on symptomatology, presuming that each symptom originates in a separate pathophysiology and demands its unique therapy. Women often present a mixture of symptoms inconsistent with urodynamic diagnosis, especially regarding urgency. LÄS MER

  3. 2. Urodynamic modelling and measurement techniques for assessment of urethral function during micturition

    Författare :Heikki Teriö; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : According to Griffiths' theory of flow through elastic tubes the urinary flow is controlled by an elastic constriction. The mechanical properties of this flow-controlling zone are described by the intrinsic urethral pressure as a function of cross-sectional area given by the pressure/area relation p(A)=pmo + KnAn, where pmo is the minimal urethral opening pressure, A the cross-sectional area and Kn and n are parameters describing the distensibility of this zone.

  4. 3. Female urinary incontinence. A study on heredity, urodynamic and hormonal factors and the evaluation of a novel surgical technique

    Författare :Maria Andrada; Lund Obstetrik och gynekologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Female urinary incontience; pelvic organ prolapse; pelvic floor disorders; urodynamics; urethral parameters at rest; surgical outcome; serum estradiol; perimenopause; TVT; TVT-Secur; familial aggregation; risk for surgery; first grade relatives;

    Sammanfattning : Abstract Pelvic floor disorders (PFD) represent a major public health issue worldwide. Aims of this work Study I: to investigate associations between preoperative resting urethral parameters (MUCP, FL and CA) and objective outcome of laparoscopic colposuspension and, if possible, to identify cutoff values useful in clinical practice.

  5. 4. The use of implants in female pelvic floor reconstructive surgery. Short and long term efficacy and safety

    Författare :Vasileios Alexandridis; Lund Obstetrik och gynekologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; implants; mid-urethral slings; pelvic floor reconstructive surgery; pelvic organ prolapse; urinary incontinence;

    Sammanfattning : Pelvic floor reconstructive surgery (PFRS) has suffered from high recurrence rates ever since its birth. Implants were thus quickly employed, initially autologous grafts and allografts. LÄS MER

  7. 5. 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.
