Summary
Percutaneous nephrostomy (PCN) performed solely with ultrasound (US) guidance is a safe and effective procedure. This study found a high success rate and low complication rate for US-guided PCN, demonstrating its utility in urinary system drainage.
Area of Science:
- Urology
- Medical Imaging
- Interventional Radiology
Background:
- Percutaneous nephrostomy (PCN) is crucial for temporary urinary system drainage.
- Traditionally, PCN uses fluoroscopic or combined sonographic and fluoroscopic guidance.
Purpose of the Study:
- To evaluate the safety and efficacy of PCN performed exclusively with real-time ultrasound (US) guidance.
- To assess the technique's success rate and complication profile.
Main Methods:
- Retrospective analysis of 273 PCN procedures in 267 patients.
- Procedures performed solely under real-time US guidance using the Seldinger technique.
- Indications included benign/malignant urinary obstruction and urinary fistulae.
Main Results:
- PCN success rate was 98.5% (269/273 attempts).
- Satisfactory catheter placement achieved in 91.1% under US guidance.
- Major complications occurred in 5.6% of patients; catheter dislodgement (12.6%) and blockage (3.3%) were noted.
Conclusions:
- Real-time sonographic guidance is a safe and effective method for performing PCN.
- US-guided PCN can be successfully utilized in most patients requiring urinary drainage.
