[Special diagnostic and therapeutic methods for changes affecting urodynamics in diseases of the urogenital tract (author's transl)].

Special diagnostic and therapeutic methods for changes affecting the urodynamics of the urogenital tract are reported from the urological point of view. First of all the causal connection between disorders of drainage and urinary infection are referred to. Then the special methods of investigation to clarify these urodynamically active urethral changes are mentioned. The radiological visualization of the urethra during miction and the retrograde introduction of contrast media are particularly stressed. In connection with this the endoscopic verification of these pathological changes is emphasized. A number of very demonstrative pathological changes in the region of the entire subvesicular urinary tract are demonstrated both by X-ray and uroscopic pictures. Finally the therapeutic possibilities are reviewed in relation to the findings.
