Extraction of trapped double J in ureteroscope: a novel technique



Urological endoscopes and percutaneous devices are expensive and their maintenance and cleaning need special attention. Sometimes urologists can help repairing their devices.

Case description

During taking out a Double J, Double J was trapped in the working channel of ureteroscope unintentionally. It was not possible to take it out by pushing methods. Finally, Double J was pulled out by a changed nephrostomy needle to a small curve hook.


Using the hand-made hook to pull out a trapped Double J from ureteroscope does not destroy the device.
