Randomized Controlled TrialTranexamic acid reduces blood loss during percutaneous nephrolithotomy: a prospective randomized controlled study.
Bleeding is a significant morbidity associated with percutaneous nephrolithotomy. This study was conducted to evaluate the safety and efficacy of the antifibrinolytic agent tranexamic acid in reducing blood loss in patients undergoing percutaneous nephrolithotomy. ⋯ The use of tranexamic acid in percutaneous nephrolithotomy is safe, and is associated with reduced blood loss and a lower complication rate.

High grade renal injuries: application of Parkland Hospital predictors of intervention for renal hemorrhage.
Investigators from Parkland Hospital proposed substratification of the AAST (American Association for the Surgery of Trauma) grading scale based on 3 risk factors, including active vascular extravasation, a medial laceration and a perinephric hematoma of greater than 3.5 cm. We hypothesized that these characteristics would also be associated with intervention for renal hemorrhage in our large trauma series. ⋯ Vascular extravasation, a perinephric hematoma greater than 3.5 cm and the number of risk factors (0 to 3) were associated with intervention for renal hemorrhage. Our findings are similar to those at Parkland Hospital. These imaging features may serve as useful prognostic indicators for renal trauma.

Detection of normal intratesticular perfusion using color coded duplex sonography obviates need for scrotal exploration in patients with suspected testicular torsion.
Although color coded duplex sonography is useful for visualizing testicular perfusion in patients with clinical suspicion of testicular torsion, fear of overlooking the condition itself remains. Thus, routine scrotal exploration in every patient with acute scrotal pain is common at many centers. We assessed the efficacy of color coded duplex sonography in predicting the need for scrotal exploration in patients with clinical suspicion of testicular torsion. ⋯ Our data provide evidence that routine surgical exploration is no longer justified in patients with clinical suspicion of testicular torsion if color coded duplex sonography has revealed normal intratesticular perfusion.
