ORLANDO, FL USA (UroToday.com) - Presented by Margaret S. Pearle, MD, PhD, on behalf of the MMKS Guideline Panel* at the American Urological Association (AUA) Annual Meeting - May 16 - 21, 2014 - Orlando, Florida USA
ORLANDO, FL USA (UroToday.com) - Percutaneous renal access can be challenging in complex cases with large stone burden (i.e., staghorn calculi) or a special kidney anatomy.
ORLANDO, FL USA (UroToday.com) - Access in PCNL cases remains challenging. The study group presented a novel approach combining direct ureteroscopic visualization of access location with ultrasound guidance. They aimed to compare outcomes in patients with US-guided percutaneous renal access to conventional fluoroscopic guided access.
ORLANDO, FL USA (UroToday.com) - There is a known association between hypertension (HTN) and nephrolithiasis. Abnormalities in renal calcium metabolism in hypertensive patients can lead to increased urinary calcium excretion. The research group sought to evaluate differences in 24-hour urine parameters between patients with and without HTN in a large cohort of stone formers.
ORLANDO, FL USA (UroToday.com) - Uric acid (UA), and its physiological relevant anion urate, represent the final breakdown products of the purine degradation pathway in humans.
ORLANDO, FL USA (UroToday.com) - The treatment plans patients receive from their physicians because of renal stones is not always followed through due to changes in patients’ attitudes over time. Kristina L Penniston and colleagues assessed patients’ experiences with compliance with preventative regimens for treatment of renal stones.
ORLANDO, FL USA (UroToday.com) - Calcium phosphate stones are more common in basic urine pH. Thus, there is concern that the potassium citrate (KCIT) may increase the formation of this subtype of renal stones. As a result, Sara L Best and colleagues wanted to evaluate stone composition and 24-h urinary parameters in patients on KCIT.
ORLANDO, FL USA (UroToday.com) - Thomas Chi and colleagues developed a method of screening single gene knockdown candidates for their ability to prevent the formation of urinary stones utilizing Drosophila.
ORLANDO, FL USA (UroToday.com) - Litholink Corporation has recently developed a solid-phase assay, cystine capacity, that is thought to be a more reliable estimate of stone-forming potential than cystine concentration. To date, the recommended capacity target of > 150 mg/L has not been directly correlated with clinical stone recurrence.
ORLANDO, FL USA (UroToday.com) - Usually preoperative urinalysis (UA) and urine culture are obtained before percutaneous nephrolithotomy (PCNL), and positive UC should be adequately treated prior to percutaneous surgery.
