Investigation of the Suburothelial Myofibroblast Network and of Smooth Muscle Function and Control in the Human Urinary Outflow Tract

March 2, 2012 updated by: Alexander Roosen, Ludwig-Maximilians - University of Munich

Investigation of the Suburothelial Myofibroblast Network and of Smooth Muscle Function and Control in the Continent and Incontinent Human Urinary Outflow Tract

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.

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

Description

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.
