To evaluate the prevalence and characteristics of crossing vessels in asymptomatic patients with a radiographically normal ureteropelvic junction.We retrospectively reviewed the computed tomography angiography images of 601 patients who were evaluated for possible living organ donation at the University of Minnesota from 2005 to 2008. One patient had asymptomatic hydronephrosis and was excluded from...
To elucidate the effect of a patient-centered combined nutritional and medical therapy approach on stone disease management, guided by 24-hour urinary stone risk.We retrospectively analyzed the records of patients treated at our multidisciplinary stone clinic from July 2007 to February 2009. Included were adult stone formers who presented with severe urinary abnormalities or whose urinary parameters...
To investigate the use of fish oil in the dietary management of hypercalciuric stone formers. Prostaglandins have been linked to urinary calcium excretion, suggesting a role for omega-3 fatty acids in the treatment of hypercalciuric urolithiasis. We retrospectively studied a cohort of patients treated at our stone clinics from July 2007 to February 2009. Patients' urinary risk factors for stone...
To examine the effects of dietary manipulation and pyridoxine medical management for idiopathic hyperoxaluria in patients with nephrolithiasis.A retrospective longitudinal study of the patients treated in our stone clinics from July 2007 to February 2009 was performed. All patients were evaluated with pre- and postintervention 24-hour urine collection and met a registered dietician. Recommendations...
To evaluate the durability of 4 next-generation flexible ureteroscopes in a randomized, multi-institutional, prospective study.Patients at 3 institutions were randomized to 1 of 4 flexible ureteroscopes: the Wolf Viper, Olympus URF-P5, Gyrus-ACMI DUR-8 Elite (DUR-8E), and Stryker FlexVision U-500. Each center used 1 scope from each manufacturer until it needed major repair (primary endpoint). Intraoperative...
Purpose The rate of unintentionally discovered renal masses has been increasing along with a parallel increased incidence of renal cell carcinoma both in men and women. Ablation therapy has emerged as an alternative for the treatment of these small renal tumors. Several techniques have been developed for renal tumor ablation with cryoablation (CA) and radiofrequency ablation (RFA) being among the...
