The most powerful device-Biophilia NLS
The most statistically reliable method of Biophilia NLS-research in case of urinary bladder tumors is an ultramicroscopic research with the usу of spectral-entropy analysis. Such method provides the detection of the tumor less than 3 mm., specifies its localization and in case of its invasive form it allows specifying its proportion in relation to adjacent organs and tissues. It is possible to examine the layers of bladder wall in all patients when using 4D NLS-ultramicroscopic research. We use spectral-entropy analysis in case of any process localization in urinary bladder after performance of ultramicroscopic research. Only endocavitary ultramicroscopic research is the most effective method for examination of all tumor aniages in case of multicentric growth.
The visualization of small sized formations (less than 4 mm.) is complicated in case of common non-scaling NLS-research; in more rarely cases the visualization of larger tumors located on the frontal urinary bladder wall is complicated. Performance of spectral-entropy analysis with ultramicroscanning always helps to make correct diagnosis in cases like these. The frontal urinary bladder wall which is put close to an abdominal wall is visualized with considerable zooming in, which allows examining both wall layers and their correlation with tumor nodule.
Common 2D NLS-research (which was put high hopes on) did not obtain widespread use in our country. Such method allows good visualization of superficial formations though relatively large ones (from 6-8 mm).
In case of deep invasion it is not always possible to estimate the exterior contour of the tumor. These peculiarities lower the effectiveness of 2D NLS-graphy method in detection of invasion depth into the bladder wall.
At the present time we are able to use extensively NLS-research of urinary bladder tumors with 4D reconstruction. The method allows visually presentation of the tumor and its correlation with surrounding tissues when making decision on choosing of surgical procedures type, and it allows storing the information in digital format.
Information storing provides the possibility for attending doctors to subsequently review the whole 4D information block which gives more objectiveness to 4D NLS-research.
