ReviewAssociation of gadolinium based magnetic resonance imaging contrast agents and nephrogenic systemic fibrosis.
We investigated the recently discovered association between gadolinium based magnetic resonance imaging contrast agents and the development of nephrogenic systemic fibrosis in patients with chronic kidney disease or acute kidney injury. ⋯ Magnetic resonance imaging using gadolinium based contrast agents must be performed judiciously in patients with renal dysfunction, carefully weighing on a case by case basis the benefits of magnetic resonance imaging and the risk of nephrogenic systemic fibrosis as well as the disadvantages of undergoing alternative or foregoing imaging studies.

Surgical education is changing rapidly as several factors including budget constraints and medicolegal concerns limit opportunities for urological trainees. New methods of skills training such as low fidelity bench trainers and virtual reality simulators offer new avenues for surgical education. In addition, surgical simulation has the potential to allow practicing surgeons to develop new skills and maintain those they already possess. We provide a review of the background, current status and future directions of surgical simulators as they pertain to urology. ⋯ Surgical simulation is an exciting area of surgical education. The future is bright as advancements in computing and graphical capabilities offer new innovations in simulator technology. Simulators must continue to undergo rigorous validation studies to ensure that time spent by trainees on bench trainers and virtual reality simulators will translate into improved surgical skills in the operating room.

Review Comparative StudyContrast medium induced nephropathy in urological practice.
Contrast medium induced nephropathy is the third cause of in-hospital acute renal failure. The first studies in this area were done with reference to urological practice only. Although various guidelines on the management of contrast medium induced nephropathy were provided by the European Society of Urogenital Radiology, more recently many investigators have focused their attention on contrast medium use in interventional vascular radiology and cardiology. We critically reviewed the literature to clarify the impact of contrast medium induced nephropathy in urology and the possible prophylactic measures against it. ⋯ The general approach to the recognition and prevention of contrast medium induced nephropathy in patients at risk should be extended to urological clinical practice since no definitive evidence based data are available regarding contrast medium induced nephropathy management in urological patients. Moreover, these patients can frequently present with the most significant risk factor for contrast medium mediated kidney damage, that is preexisting acute or chronic renal failure. Controlled trials are needed to establish the incidence of contrast medium induced nephropathy in diagnostic or interventional procedures in uroradiology.

ReviewKlippel-Trenaunay syndrome: incidence and treatment of genitourinary sequelae.
Prior reviews regarding genitourinary manifestations of Klippel-Trenaunay syndrome used data acquired from diverse specialty specific articles to define the incidence and sequelae of its genitourinary manifestations. We believe that this resulted in erroneous conclusions regarding the urological complications of Klippel-Trenaunay syndrome. ⋯ The incidence of genitourinary manifestations of Klippel-Trenaunay syndrome is 30%, which is triple the previously reported incidence of 9%. Unlike prior reports stating that the genitourinary abnormalities rarely caused problems, 52% of the patients (34 of 66) with Klippel-Trenaunay syndrome who had urological manifestations eventually required interventional therapy for genitourinary complications.
