The stent includes a hood-valve at it vesical end to prevent urinary reflux. The hood-valve compris a hood-shaped plastic foil that partially surrounds the external circumferential surface of the catheter at the oblique vesical end opening. The hood-valve is open in its resting state so as to allow the urine to flow out through the vesical outlet, unimpeded by the hood-valve, and folds over to clo the vesical outlet in respon to a reflux pressure generated due to a pressure differential between the catheter and the bladder. The valve remains clod until the pressure differential subsides. The urine flows into the catheter via multiple lateral openings in the upper and middle portions thereof. A gelatin cap generally enclosing the valve may be slipped over the vesical end of the catheter to rve as a stop for the guide-wire during inrtion of the stent in a patient. The gelatin cap is pushed off by the guide-wire into the bladder where is it dissolved in the urine. This arrangement permits inrtion of the catheter from above without damaging hood-valve during surgical procedures.vicky是什么意思
