Knotted ureteral stent: a minimally invasive technique for removal.
OBJECTIVE
We describe a useful technique for untying a knotted ureteral catheter.


METHODS
An Amplatz super stiff guide wire was advanced through the lumen of the stent and with uniform force the knot was untied.


RESULTS
The knot was untied and the stent was removed. A nephrostomy tube or other more invasive techniques for removal were avoided.


CONCLUSIONS
An Amplatz super stiff guide wire passed retrograde via the ureteral stent lumen should be considered as a valid alternative to percutaneous removal of a knotted ureteral stent.
