[Endosonography of the ureter--initial experience with a new method].
The authors had the opportunity to examine four patients, using a new intraureteral sensing unit and to study the basic ultrasonographic picture of the whole ureter. In addition to the ascendent application of the sensing unit they used also the descendent approach during percutaneous lithotripsy and peroperative exploration of the ureter during ureterotomy. The authors assume that the method will prove useful in particular for detection and assessment of the position of renal vessels before endopyelotomy in hydronephrosis.
