The re-entry nephrostomy catheter for endourological applications

Area of Science:

• Urology
• Medical Devices
• Nephrology

Background:

• Endourological procedures often require specialized instrumentation for optimal outcomes.
• Percutaneous nephrolithotomy and stone extraction necessitate reliable access and drainage solutions.

Purpose of the Study:

• To introduce a versatile re-entry nephrostomy catheter designed for various endourological applications.
• To highlight the catheter's utility in facilitating complex procedures like 2-stage percutaneous nephrolithotomy and post-operative drainage.

Main Methods:

• Development of a 24F self-retaining catheter with an 18 cm extension.
• Utilizing the catheter for ureteral access and safety guide wire introduction during percutaneous nephrolithotomy.
• Employing the catheter as a drainage tube and stent after 1-stage stone extraction.

Main Results:

• The catheter provides necessary ureteral access for guide wire introduction in 2-stage percutaneous nephrolithotomy.
• The device functions effectively as a drainage tube and stent in the post-operative setting of 1-stage stone extraction.

Conclusions:

• The developed re-entry nephrostomy catheter offers a versatile solution for multiple endourological procedures.
• This innovation simplifies surgical steps and improves patient outcomes in stone management and urinary drainage.
