Direct renal sympathetic denervation methods are detailed, alongside measuring renal norepinephrine levels. This technique validates denervation success and assesses reinnervation in experimental models.
Area of Science:
- Nephrology
- Surgical Techniques
- Neuroscience
Background:
- Renal sympathetic denervation (RSD) is an established experimental technique.
- Current methods include dorsal rhizotomy and direct renal denervation using phenol.
- A clinical marker for successful RSD or overactivity is lacking.
Purpose of the Study:
- To introduce comprehensive methods for direct renal sympathetic denervation.
- To detail the measurement of renal norepinephrine content levels.
- To establish a validation method for experimental RSD.
Main Methods:
- Direct renal sympathetic denervation by stripping renal nerve bundles.
- Application of 10% phenol in ethanol solution to remove residual nerves.
- Measurement of renal norepinephrine content levels to assess denervation efficacy.
Main Results:
- Successful renal sympathetic denervation is validated by decreased renal norepinephrine levels in experimental models.
- This method allows assessment of incomplete denervation and reinnervation.
- Provides a reliable experimental validation technique.
Conclusions:
- Comprehensive methods for direct renal sympathetic denervation and norepinephrine measurement are presented.
- These techniques enable validation of experimental renal sympathetic denervation.
- Facilitates assessment of denervation completeness and reinnervation over time.
