Summary
A new technique uses a biopsy needle to place a guidewire, maintaining access to the kidney when a nephrostomy catheter is blocked by concretions. This method overcomes the challenge of straightening the catheter
Area of Science:
- Urology
- Interventional Radiology
- Nephrology
Background:
- Obstructed Cope nephrostomy catheters can be difficult to manage when the retaining thread is fixed by calculus.
- Loss of access to the collecting system complicates patient care and requires timely intervention.
