简介：
Overview
This article describes a technique for transurethral catheter insertion aimed at delivering active substances into the urinary bladder and/or prostate of adult male mice. The method addresses challenges associated with the natural curvature of the urethra and the thinness of the urethral wall.
Key Study Components
Area of Science
- Neuroscience
- Urology
- Animal Models
Background
- Transurethral instillation is not well documented in existing literature.
- The technique is essential for studying bladder pathology.
- It aids in understanding lower urinary tract diseases in males.
- Challenges include urethral curvature and the need for repeated substance instillation.
Purpose of Study
- To provide a detailed method for catheter insertion.
- To facilitate intravesical delivery of treatments.
- To improve the study of bladder pathology in animal models.
Methods Used
- Select appropriate PE tubing size based on the target organ and animal age.
- Cut a 2.5-inch long piece from the tubing.
- Dull the sharp edge of a compatible needle.
- Introduce the needle into the tubing lumen carefully.
Main Results
- The technique allows for effective substance delivery.
- It can induce animal models of bladder pathology.
- Evaluation of intravesicular treatment effectiveness is possible.
- Addresses the anatomical challenges of male urethra.
Conclusions
- The described method is a valuable tool for researchers.
- It enhances the understanding of bladder diseases.
- Future studies can build on this technique for further insights.
What is transurethral instillation?
Transurethral instillation is a procedure for delivering substances directly into the urinary bladder through the urethra.
Why is this technique important?
It allows researchers to study bladder pathology and evaluate treatments in animal models.
What challenges are associated with this procedure?
Challenges include the natural curvature of the urethra and the thinness of the urethral wall.
How do you prepare for the procedure?
Select the appropriate tubing size and prepare the needle for insertion into the tubing.
What are the main advantages of this method?
It enables effective substance delivery and the creation of animal models for bladder pathology research.
