Percutaneous access of nondilated renal collecting systems.
Interventional radiology (IR) has seen an increase in the numbers of patients referred for urinary diversion in patients with ureteral leaks. This increase has corresponded to the increasing use of complicated surgical procedures for lower urinary tract tumors. These procedures are often relatively difficult to perform for two reasons: first, the renal collecting systems are typically completel...
متن کاملReal-time tomographic reflection in facilitating percutaneous access to the renal collecting system.
BACKGROUND AND PURPOSE Real-time tomographic reflection is a novel technique that uses a geometrically fixed arrangement of a conventional ultrasound transducer, a transducer-incorporated monitor, and a half-silvered mirror. This device, dubbed the Sonic Flashlight, generates a virtual anatomically scaled image, obviating the need for a separate monitor. It may therefore facilitate invasive pro...
متن کاملStereotactic mechanical percutaneous renal access.
Obtaining accurate percutaneous renal access when treating intrarenal disease requires substantial skill. Robotic devices have been used in a variety of surgical applications and have been successful in facilitating percutaneous puncture while improving accuracy. Laboratory models of robotic devices for percutaneous renal access have also been developed. However, several technical hurdles need ...
متن کاملPercutaneous nephrolithotripsy: C-arm CT with 3D virtual navigation in non-dilated renal collecting systems.
PURPOSE We aimed to evaluate the clinical superiority of using C-arm computed tomography (CT) to establish percutaneous nephrolithotripsy (PCNL) access for patients with non-dilated renal collecting systems. METHODS From May 2014 to May 2015, 33 patients underwent C-arm CT-guided puncture to establish PCNL access after failed attempts of ultrasonography-guided nephrostomy. Technical success, ...
متن کاملPercutaneous Renal Access: A Historical Perspective
Percutaneous nephrolithotomy (PCNL) has evolved to become the preferred minimally invasive approach for treating large-burden renal stones. This approach has replaced open renal surgery for stones. It has also evolved into a treatment option for treating noninvasive urothelial tumors of the upper urinary tract. Current percutaneous access techniques involve fluoroscopic or ultrasound guidance w...
