Ultrasound Contrast Agent-Assisted Guidance for Percutaneous Nephrostomy in Non-Hydronephrotic Kidneys
This study explored the use of ultrasound contrast agent (UCA)-assisted guidance for percutaneous nephrostomy (PCN) in patients with non-hydronephrotic kidneys, a condition that makes traditional ultrasound guidance more challenging. The research involved 13 patients (20 kidneys) who underwent PCN from January 2017 to August 2023. Despite the lack of significant dilatation in the renal collecting system, the procedure had a 100% success rate, with no major complications reported. The ultrasound contrast agent was injected into the renal pelvis during the procedure, enhancing imaging clarity and aiding the accurate placement of the puncture needle. The average amount of UCA used was 19 mL, and the procedure typically took around 19 minutes, with most patients requiring only a single puncture. All patients experienced significant symptom relief post-operation.
Enhanced Efficacy and Safety of UCA-Assisted Ultrasound
Compared to conventional methods, the UCA-assisted ultrasound guidance for PCN provided a more effective and safer solution for non-hydronephrotic kidneys. The study demonstrated a simplified operative process while maintaining a high success rate, suggesting that this approach can significantly improve patient outcomes in cases where traditional PCN methods are less effective. Given its potential advantages, this technique may become a valuable tool for managing non-hydronephrotic kidney conditions, which are often overlooked in clinical settings due to the challenges of performing PCN. This study presents UCA-assisted ultrasound guidance as a novel and promising method to address these difficult cases, offering a reliable alternative for urinary diversion and symptom alleviation.
