Summary
CT- and fluoroscopy-guided percutaneous nephrostomy tube (PNT) placement is effective, achieving 97% success with low complication rates. This technique allows routine PNT procedures with patients in the supine or supine-oblique position.
Area of Science:
- Interventional Radiology
- Medical Imaging
Background:
- Percutaneous nephrostomy tube (PNT) placement is a common urological procedure.
- Traditional PNT placement often requires patients in the prone position.
Purpose of the Study:
- To present experience with CT- and fluoroscopy-guided PNT placement.
- To describe the technique for PNT placement in the supine-oblique position.
Main Methods:
- A combined CT scanner and C-arm fluoroscopy system was utilized.
- CT localization and fluoroscopic guidance were employed for PNT placement.
- 148 PNT placements were attempted in 129 patients, primarily in supine or supine-oblique positions.
Main Results:
- Successful PNT placement was achieved in 97% (144/148) of cases.
- 81% (101/124) of PNTs in native kidneys were placed with patients in the supine-oblique position.
- A low complication rate was observed: 2% minor complications and 1% catheter dislodgments, with no major complications.
Conclusions:
- CT-fluoroscopy control enables routine PNT placement in supine or supine-oblique positions.
- This technique is associated with a low complication rate.
- The supine-oblique position is feasible and effective for PNT placement.
