  6. Acute Kidney Injury Cause: split into pre-renal, renal and post-renal Presentation: 1st – reduced urine output (<0.5ml/kg) 2nd – raised creatinine, urea, K+, ↓eGFR 3rd – confusion, vomiting, overload Treatment: pre-renal - ? Renal – biopsy, steroids, removal, dialysis Post-renal - ? The Peer Teaching Society is not liable for false or misleading information…

  8. The prostate The Peer Teaching Society is not liable for false or misleading information…

  10. Prostate cancer 80% of men in 80s have prostate cancer but only causes 13% of all cancer deaths. Symptoms: as before + bony pain, weight loss. PSA – 1000 screened: how many deaths prevented? how many false positives? Investigation – TRUS-prostate, radioisotope/MRI Treatment – watchful waiting & monitor anti-androgen therapy prostatectomy/radiotherapy – complications? The Peer Teaching Society is not liable for false or misleading information…

Quiz? • Which other structure in the retroperitoneum may have pathology that mimics upper UTI and needs urgent treatment? • Why do middle aged women have more UTIs? • A 120kg man on the ward has a urine output of 45mls in the last hour.
