[Stereoroentgenology in endourology].

Area of Science:

• Urology
• Medical Imaging
• Surgical Technology

Background:

• Percutaneous renal surgery requires precise targeting of kidney structures.
• Traditional imaging methods may have limitations in providing real-time, three-dimensional visualization during procedures.

Purpose of the Study:

• To introduce and evaluate the use of three-dimensional stereofluoroscopy for percutaneous renal surgery.
• To assess the impact of this technology on procedural accuracy, surgeon training, and patient safety.

Main Methods:

• Utilized a laboratory prototype equipment with a grid-controlled X-ray tube for sequential image capture.
• Employed digital image processing and storage to separate images into pairs for 3-D display.
• Applied the technique for guiding percutaneous nephrolithotomy.

Main Results:

• Achieved exact and rapid puncture of suitable calyces for percutaneous nephrolithotomy.
• Demonstrated a shortened learning process for endourologists.
• Observed a reduction in radiation exposure, enhancing procedural safety.

Conclusions:

• Three-dimensional stereofluoroscopy is a valuable tool for percutaneous renal surgery.
• The technology improves targeting accuracy, simplifies surgeon training, and increases patient safety through reduced radiation exposure.
