Résumé
In recent years, the research on upper urinary tract urodynamics has been developing toward digitalization, simulation and noninvasive.This article reviews the physiological mechanism, clinical application and new research progress of upper urinary tract urodynamics. Pacemaker cells are considered to be the basis of upper urinary peristalsis, but the specific mechanism remains to be further studied. The dynamic technique of upper urinary tract is widely used in clinical practice to measure the perfusion rate-pressure relationship. Whitaker test can be used as an auxiliary examination in the diagnosis of suspicious cases. Artificial intelligence, three-dimensional reconstruction and other multidisciplinary integration may be the important means for the research in the future.
Résumé
Objective To study the effect of flushing the pelvis with normal saline at constant pressure on renal function to provide a theoretical basis of pathogenesis of renal injury during endoscopic procedures. Method Fifty rabbits underwent tube ureterocutaneostomy as a method of urinary diversion, the flushing group perfused immediately after ureterocutaneostomy, and the intrapelvic pressure is 60, 80, 100, 120cmH_2O, but the sham-operated group didn′t flush. Urinary protein excretion were examined every day after operation,we also got pathological examination of nephridial tissue continually. The urinary protein include immunoglobulin G, microalbuminuria and ?_2-microglobulin. Result All the flushed rabbits had the change of urinary protein, the difference of urinary protein was of statistical significance between the before and the first day after treatment(P
