  Purpose

Painful bladder syndrome (PBS)/interstitial cystitis (IC) may be due to the actions of nitric oxide (NO) in the bladder tissue. NO is a gaseous substance with a very short half-life, synthesized by a group of NO-synthase-enzymes in many tissues.

The goal of this study is to illuminate bladder tissue production of NO in individuals with PBS and healthy individuals, by quantification of NO and NO-enzyme expression by different molecular biological methods.


Condition Intervention
Interstitial Cystitis
Bladder Diseases
Urinary Incontinence
Procedure: Tissue examination for protein- and mRNA-expression of NO

Study Type: Observational
Study Design: Observational Model: Defined Population
Time Perspective: Cross-Sectional
Official Title: A Quantitative Analysis of Protein- and mRNA-Expression of Nitric Oxide Syntheses and Their Functional Role in Human Urothelium
