    Acute urinary retention and the difficult catheterization: current emergency management.
    (2016) Sliwinski, Ania; D'Arcy, Frank T; Sultana, Ron; Lawrentschuk, Nathan
    Acute urinary retention (AUR) is a common presentation to emergency departments. This article updates the reader on the appropriate management, investigations and guidelines for AUR. It looks at the mechanism of normal micturition and describes the theories of AUR. It outlines urethral catheterization techniques for difficult cases, reviews suprapubic catheterization procedures and describes the management of AUR in polytrauma. Although emergency management is by bladder drainage, key points in the history and examination may expose significant, latent pathologies.

    Testicular torsion and the acute scrotum: current emergency management.
    (2016) Ta, Anthony; D'Arcy, Frank T; Hoag, Nathan; D'Arcy, John P; Lawrentschuk, Nathan
    The acute scrotum is a challenging condition for the treating emergency physician requiring consideration of a number of possible diagnoses including testicular torsion. Prompt recognition of torsion and exclusion of other causes may lead to organ salvage, avoiding the devastating functional and psychological issues of testicular loss and minimizing unnecessary exploratory surgeries. This review aims to familiarize the reader with the latest management strategies for the acute scrotum, discusses key points in diagnosis and management and evaluates the strengths and drawbacks of history and clinical examination from an emergency perspective. It outlines the types and mechanisms of testicular torsion, and examines the current and possible future roles of labwork and radiological imaging in diagnosis. Emergency departments should be wary of younger males presenting with the acute scrotum.
