Percutaneous renal puncture: requirements and preliminary results

TL;DR

This paper presents a computer-assisted method for percutaneous renal puncture that combines 3D pre-operative planning with real-time guidance using CT and ultrasound data, demonstrated on a phantom with promising results.

Contribution

It introduces a novel system integrating CT and ultrasound imaging for precise, guided renal puncture with initial validation on a phantom model.

Findings

Successful millimetric registration on real data

Encouraging guidance results on a kidney phantom

Potential for improved accuracy in renal puncture procedures

Abstract

This paper introduces the principles of computer assisted percutaneous renal puncture, that would provide the surgeon with an accurate pre-operative 3D planning on CT images and, after a rigid registration with space-localized echographic data, would help him to perform the puncture through an intuitive 2D/3D interface. The whole development stage relied on both CT and US images of a healthy subject. We carried out millimetric registrations on real data, then guidance experiments on a kidney phantom showed encouraging results.
