“…Subtraction of the two images enhances the contrast material and thus the appear ance of the vessels. The clinical applicability of the technique has been discussed by Hricaket al [26]. 378 Am J Nephrol 1997:17:369-381 H icrholzcr/l I ierholzer We turn now to the last group of imaging techniques which have been designed to image tubular characteristics (table 9).…”

“…This is the price, sometimes a very high price, we have to pay for obtaining real-time information by noninvasive techniques. We should also be aware that addi tional physical principles and new methods are presently being explored, including positron-emission tomography, single-photon-emission tomography ar.d even biomagnetic techniques [26], which may even be more elaborate and expensive.…”

The ancient approach to obtain an image of the kidneys (and other internal organs) was ‘section-inspection-imaging’ by drawing, painting, sculpturing, and modelling. The present study follows chronologically the development and use of sectioning techniques from ancient (often forbidden) methods to modern microdissection and maceration of silicone-rubber-injected tubules. Inspection evolved from the use of the naked eye to magnifying lenses, microscopes and finally electron microscopy. Pertinent examples such as the description of the kidneys as the site of urine formation, the visualization of loop structures in the renal medulla and the imaging of tight junction strands are discussed. Inspection or visualization of renal structure and function has been revolutionized by modern noninvasive techniques, such as X-ray imaging, imaging by radioisotopes, ultrasound, computer tomography and nucelar magnetic resonance. Pertinent examples are given demonstrating the potency of the various techniques. The contribution of computerized data evaluation is discussed. The development of micropuncture and microperfusion techniques has opened the field for direct imaging not only of renal (sub)structural details but also of functional parameters such as transtubular reabsorption rates, single gfomerular capillary filtration and conductance of the paracellular pathway. We focus particularly on techniques specifically designed to visualize renal hemodynamic and transport parameters.

After X-rays were detected and cystoscopes had become available, progress in nephrology depended on the development of contrast media which would permit imaging of the kidneys and the urinary system. We describe how A. Binz and C. Räth, two chemists at the Agricultural Academy in Berlin, synthesized iodinated derivatives which were potent chemotherapeutics. Moses Swick tested the substances in the clinics of L. Lichtwitz (Hamburg) and A. von Lichtenberg (Berlin) and discovered a rapid renal excretion. He also observed that an iodinated N-acetylated derivative, later named Uro-Selectan, amplified X-ray contrast after intravenous application. With this substance and other derivatives which were produced by Schering-Kahlbaum AG, the door was open for excretion urography.
