Impact of Sodium Bicarbonate on 24-hour Urine Parameters in Hypocitriuric and Uric Acid Stone Formers
Recruiting
The incidence of kidney stone disease continues to rise globally. Although the treatment of kidney stone disease has dramatically improved in recent years, surgical management remains invasive and expensive. Patients who develop kidney stones are at high risk of recurrence during their lifetime; therefore, prevention of stones should be a primary focus. Low levels of citrate and acidic urine are risk factors for the formation of kidney stones such as calcium oxalate and uric acid, respectively.... Read More

Accelerated Flap Coverage in Severe Lower Extremity Trauma
Recruiting
The goal of this randomized controlled trial is to determine if accelerated flap coverage compared to standard flap coverage timing leads to improved infection-related complications in patients with open fractures and/or dislocations below the knee. Eligible patients will be randomized to receive either a flap within a goal of 72 hours of injury or standard of care flap timing for the institution. The primary outcome will be a composite outcome to evaluate clinical status 6 months after randomiz... Read More
