title: Exchange of an obstructed loop nephrostomy catheter: technical note.
abstract: Straightening of the distal loop of an obstructed self-retaining "Cope" style nephrostomy catheter may be impossible when the retaining thread is fixed by concretions. We describe a transcatheter technique using an 18 gauge Turner biopsy needle to place a 0.038 inch exchange guidewire for retaining access to the collecting system.
