  Purpose

The aim is to find out if adreno-muscarinic synergy is present also in human tissues of the urinary outflow tract that have a dual adrenergic-muscarinic receptor fitting. To further characterise morphology and function of the suburothelial myofibroblast network in the human bladder outlet.

Biospecimen Description:

Human tissue from the urinary outflow tract (bladder base and urethra) of patients undergoing cystectomy or radical prostatectomy (for cancer treatment) with pre-operatively documented voiding disorders/incontinence - in particular SUI


Estimated Enrollment: 200
Study Start Date: January 2010
  Eligibility

Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   Yes
Sampling Method:   Non-Probability Sample
Study Population

Human tissue from the urinary outflow tract (bladder base and urethra) of patients undergoing cystectomy or radical prostatectomy (for cancer treatment) with pre-operatively documented voiding disorders/incontinence - in particular SUI

Criteria

Inclusion Criteria:

Tissue will be collected from the operation theatre only after having obtained the patient´s consent and in strictest accordance with histopathological requirements, i.e. after assessment of resection margins. It might be necessary to retrieve the tissue from the pathologist after first pathological assessment is completed. Tissue will be placed in Tyrode´s solution, gassed with 95 % O2 and 5 % CO2, for functional and RT-PCR or Western blot experiments, or in OCT (optimal cutting temperature) compound, snap-frozen in liquid nitrogen, and stored in a -80°C freezer until cutting for immunohistochemical experiments.

Exclusion Criteria:

None.
