“…Multiplanar reconstructions using 3D volume rendering may overcome these limitations and decrease the need for IVU for planning punctures. 30,31 The new generation Dual Energy CT (DECT) devices improve imaging of urinary calculi with half dose radiation. DECT provides the same anatomical information and gives far more detail about stone information without extracting the stone.…”

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.

“…Precise measurements of stone size can be achieved in all dimensions using 3D techniques. 1 Stone size is a critical determinant in the management of patients with calculous disease. In an in vitro study of 50 renal calculi using an abdominal phantom, imaging was performed with 3D spiral CT, radiography, and linear tomography.…”

The applications of three-dimensional (3D) CT techniques encompass a spectrum from calculus disease to preoperative planning. With proper selection of display windows and levels, accurate measurement of stone size can be achieved, along with volumetric information. A CT scan with reconstruction may help guide the direction of an endopyelotomy incision away from crossing vessels. The benefits of 3D CT in the evaluation of living renal donors include lower cost and decreased patient morbidity. In renal allograft recipients and other patients, the study may be used to investigate hypertension. Also, 3D CT is invaluable in planning nephron-sparing surgery for renal masses. The ultimate role of this modality rests in the hands of clinicians who can benefit from them and the radiologists who must provide the high-quality images and the interpretive expertise.

Objectives: To examine the predictive effect of preoperative measurements of stone volume (SV) against stone area (SA) on stone-free status (SF) following retrograde intrarenal surgery (RIRS). Methods: We retrospectively examined the medical records of 68 RIRS patients with renal calculi who were eligible. Patients having non-contrast computed tomography ( NCCT ) before and subsequent to RIRS were included, however staghorn stones and inability to access were omitted. SF status was determined by the absence of visible stones on the NCCT three months after RIRS. Using a software reconstruction tool using 3-D NCCT, a radiologist determined stone load characteristics, such as SA and SV. Using a logistic regression model, the assessment of potential SF status determinants was conducted. Results:Age, stone density, quantity and position of stones, usage of access sheath, failed prior Shock Wave Lithotripsy (SWL), and procedures were not substantially linked with non-SF status, however gender (p = 0.014), SA (p
