URETERAL STENTING USING A COMBINED ANTEGRADE RETROGRADE PROCEDURE - ATECHNIQUE FOR DIFFICULT CASES/

Ureteral stenting is a procedure of daily routine. There are however c ases in which cystoscopic placement of a stent fails despite various t echnical aids. Percutaneous nephrostomy is usually performed in those patients. In some cases however it is no reasonable alternative. For t hese special cases we used a combined antegrade/retrograde technique c onsisting in antegrade guide wire insertion followed by retrograde ure teral stenting. In 8 of 12 cases it was finally possible to insert a u reteral stent with this method. To our mind this technique should be a pplied when other attempts of stenting have failed and percutaneous ne phrostomy is no reasonable alternative.
