Les obstructions à l'écoulement urinaire : méthode de mesure de la résistance, modélisation de la mécanique prostatique, particularités d'écoulement dans l'urètre

Abstract : Current methods of urinary flow resistance meausrement are inadequate because of dubious physiological and physicaf fondations. The companson of fiquid and gas micturnions proves the variability of the urethral opening. A resistance measurement method based on physics and physiology is proposed. A detailed description of the principles of an equipment allowing to measure urinary jet speed and bladder pressure by a minimally invasive method is proposed. The mechanics of normal prostate and of BPH is modellised by finite elements method. The urethral opening is measured according to the nodules composition and the geometry. There is no correlation between prostate volume and urinary discomfort. Obstruction causes are examined according to their nature and location. Physical methods allowing the diagnosis are examined. Available therapeutic methods are judged accordinf to mechanical criteria. The obstruction associated to posterior urethra vlaves and the mechanics of intravesical reflux are explained.
