I present two discoveries together since the advantages of the ultrasonography over other diagnostic methods are based on the new ultrasound technique.
My discovery of the new technique of ultrasound examination is based on years of work, investigations and experiments. It represents a modification of the standard examination technique with exceptional performances - as if the veil was lifted from the kidneys which prevented their visualization.
Not only tuberculous changes but also other pathological conditions in the kidney are visualized much better than using standard examination. technique.
I have described the method in detail in my book “New perspective of renal tuberculosis” however, direct demonstration is the best way for the interested ultrasonographer to understand the value of the technique and acquire the skill of its application.
I will demonstrate value of the method on the following example:
Each tuberculous focus may be ultrasonographically visualized, measured and analyzed. Silent primary focus may be clearly distinguished from the excited one. Activation phase with evacuation of detritus into the collecting system is clearly visible as well as regressive changes classified by the author into initial regressive changes, advanced regressive changes … till healing. Majority of the tuberculous foci in the kidneys is either in the phase of advanced regression or healed.
IDENTIFICATION OF THE ACTIVATION PHASE IS OF THE UTMOST VALUE. THIS IS THE TIME WHEN THE SAMPLES ARE TO BE OBTAINED for Löwenstein and PCR tests!
The phase usually lasts 1-2 days, less frequently 5-6 days, or only exceptionally longer (in case of superinfections). Based on this, careful reader may conclude how useless is provision of urine samples for these examinations if the timing is not adjusted with ultrasonographic findings. It is blind sampling! If the sampling is performed in the classical way positive findings will be obtained only in presence of superinfection decelerating regression processes in the focus or in case of development of a new focus and its activation in the course of sampling. This is indeed useless in case of "pure" tuberculosis which is by far more frequent!
