[Our modifications of urethrocystography].

The modifications of urethrocystography developed by the authors aimed at reducing possible damages but securing a good diagnostic value of the method. They made it possible by applying only one instead of the originally applied six catheterizations. Previously used barium sulphate is now replaced by urographin which is less damaging to the mucous membrane of the urinary bladder. In addition, a string of metal balls, which causes injury to the urethra, is no longer used. In the first modification a catheter into which a stainless steel spiral is inserted is used. The second modification is even simpler, because it is based only on the use of different urographin concentrations. By these modifications possible iatrogenic uroinfections are significantly reduced, there is no injury of the urethra, and the time needed for the preparation and carrying out of the method is shortened to one third. In X-ray pictures contrast is not so intense as is the case with barium and metal; they are a little lighter but quite good for diagnostic purposes.
