I start a specialty night float tomorrow night which means I cover Vascular, Plastics, Transplant and Urology at our institution. I've had experience with the first three, but we do not rotate at all on Urology, we are only expected to cover their patients overnight and on weekends. I was wondering if anyone had any pearls on handling urology specific situations. I'm almost done with internship, so I can handle the majority of the general post-surgical complications/admission work/etc, I'm looking for common urologic issues that are frequently encountered that I would look like a goof if I missed or intervened inappropriately. Thanks in advance for any advice!
