Predicting calyceal access for percutaneous nephrolithotomy with computed tomography multiplanar reconstruction
OBJECTIVES Objective parameters in computed tomography (CT) scans that could predict calyceal access during percutaneous nephrolithotomy have not been evaluated. These parameters could improve access planning for percutaneous nephrolithotomy. We aimed to determine which parameters extracted from a preoperative multiplanar reconstructed CT could predict renal calyceal access during a percutaneou...
متن کاملValue of Computed Tomography for Predicting the Outcome After Percutaneous Nephrolithotomy
INTRODUCTION Computerized tomography of the urinary tract (CT-UT) has been established as the diagnostic procedure of choice for urinary stones. This study aimed to evaluate its role in predicting the outcome of percutaneous nephrolithotomy (PCNL) in terms of stone free rate and residual fragments. METHOD This prospective cohort study was conducted on 34 patients in the Urology Department of ...
متن کاملAB01. Percutaneous renal access for nephrolithotomy
Percutaneous nephrolithotomy has revolutionized the ability of the urologist to remove large burdens of renal stones over the last 15 years. In the United States, it has largely replaced open stone surgery for the treatment of large sized stones. One of the key factors in optimizing outcomes for this procedure is accurate percutaneous renal access. The guiding principles for effective renal acc...
متن کاملDevelopment of a computer assisted gantry system for gaining rapid and accurate calyceal access during percutaneous nephrolithotomy.
PURPOSE To design a simple, cost-effective system for gaining rapid and accurate calyceal access during percutaneous nephrolithotomy (PCNL). MATERIALS AND METHODS The design consists of a low-cost, light-weight, portable mechanical gantry with a needle guiding device. Using C-arm fluoroscopy, two images of the contrast-filled renal collecting system are obtained: at 0-degrees (perpendicular t...
متن کاملMultislice computed tomography vs. intravenous urography for planning supine percutaneous nephrolithotomy: A randomised clinical trial
OBJECTIVE To compare the outcome of treatment planning using multislice computed tomography (CT) or intravenous urography (IVU) for supine percutaneous nephrolithotomy (PCNL). PATIENTS AND METHODS The study included 60 patients with renal stones, all treated by supine PCNL, between March 2011 and October 2012. The patients were divided randomly into two equal groups; in group 1 30 patients ha...
