“…In the pioneer study in [23], the authors determined the feasibility and accuracy of 3D US reconstruction of the pelvicaliceal system (PCS) in an in vitro porcine kidney. A further study in [24] has demonstrated that 3D US is more accurate than 2D US for PCS measurements on a customized phantom.…”

BackgroundUltrasound (US) is a commonly-used intraoperative imaging modality for guiding percutaneous renal access (PRA). However, the anatomy identification and target localization abilities of the US imaging are limited. This paper evaluates the feasibility and efficiency of a proposed image-guided PRA by augmenting the intraoperative US with preoperative magnetic resonance (MR) planning models.MethodsFirst, a preoperative surgical planning approach is presented to define an optimal needle trajectory using MR volume data. Then, a MR to US registration is proposed to transfer the preoperative planning into the intraoperative context. The proposed registration makes use of orthogonal US slices to avoid local minima while reduce processing time. During the registration, a respiratory gating method is used to minimize the impact of kidney deformation. By augmenting the intraoperative US with preoperative MR models and a virtual needle, a visual guidance is provided to guarantee the correct execution of the surgical planning. The accuracy, robustness and processing time of the proposed registration were evaluated by four urologists on human data from four volunteers. Furthermore, the PRA experiments were performed by the same four urologists on a kidney phantom. The puncture accuracy in terms of the needle-target distance was measured, while the perceptual quality in using the proposed image guidance was evaluated according to custom scoring method.ResultsThe mean registration accuracy in terms of the root mean square (RMS) target registration error (TRE) is 3.53 mm. The RMS distance from the registered feature points to their average is 0.81 mm. The mean operating time of the registration is 6'4". In the phantom evaluation, the mean needle-target distance is 2.08 mm for the left lesion and 1.85 mm for the right one. The mean duration for all phantom PRA tests was 4'26". According to the custom scoring method, the mean scores of the Intervention Improvement, Workflow Impact, and Clinical Relevance were 4.0, 3.3 and 3.9 respectively.ConclusionsThe presented image guidance is feasible and promising for PRA procedure. With careful setup it can be efficient for overcoming the limitation of current US-guided PRA.

“…20 The accuracy of the 4D USG has been evaluated during renal puncture on experimental studies; it provides good quality punctures, such as 2D USG, but improvements in the technology should be expected. [21][22][23] The main advantages of USG are that it is portable, radiation free, cheap, and that radiolucent stones are also visible. The disadvantages are that there is a limited accuracy for renal stones and poor anatomic detail.…”

The most important step of percutaneous nephrolithotomy (PCNL) is planning the puncture site. A well selected puncture will facilitate nephroscopic navigation and stone clearance. The traditional methods for planning the puncture are intravenous urogram or retrograde pyelogram. Either of these imaging tools is adequate, but new tools such as 3D reconstructed tomography should be more accurate. Many recently developed imaging tools are promising, but no one is still ideal. The imaging techniques that we currently use have specific advantages and disadvantages. The purpose of this review is to summarise different imaging tools and their effectiveness prior to PCNL.

Three-dimensional ultrasound reconstruction of the pelvicaliceal system: an in-vitro study

Abstract: Three-dimensional ultrasound reconstruction of the porcine PCS is quantitatively comparable to corresponding casts of the PCS. 3D VR movies of the PCS were a fair representation of the PCS anatomy. 3DUS is a potential tool in the planning and execution of percutaneous renal procedures.
