    • renal failure
  4. what are the 2 categories of symptoms in BPH? and examples of each
    • Voiding problems (obstructive symptoms) and Storage problems (irritative symptoms)

  6. what is the medical management of BPH?
    • 1. alpha 1 blockers eg tamsulosin, prazosin. relax SM. SE: postural hypotension
    • 2. 5alpha reductase inhibitors eg finasteride. SE: loss libido, erectile dysfunction

  11. what is the difference between treating early and late (advanced) prostate cancer?
    • early: radical prostatectomy or watch and wait
    • late: incurable, do palliative: LHRH analogue - gosrelin or anti-androgen eg flutamide or cyproterone
  12. when thinking about PKD, which 4 organs need to be asked about?
    • brain: SAH, visual disturbance and headache (also due to high BP)
    • liver: liver failure (cysts in liver and pancreas too)
    • kidney: pyelonephritis: fever, N&V, rigors, loin pain
    • heart: mitral valve prolapse: chest pain, SOB, palps
  13. what are the signs of hypercalcaemia on ECG?
    short QT and wide T waves
  14. if you get a K+ of 7.2 in an ASYMPTOMATIC patient, what is the next best thing to do?
    • ECG
    • and repeat U&Es
    • don't just go and give calcium gluconate, insulin, dextrose as risk hypoK+. the high K may just be artefact
  15. which type of testicular tumour is commonest in 20-30years?
    teratoma
  16. what type of testicular tumour is commonest in 30-40 years?
    seminoma

    in chronic bacterial prostates: get perineal pain
  18. which drugs can cause acute urinary retention?
    anticholinergics: TCA, antipsychotics eg chlorpromazine, opiates
  19. which drugs are used in BPH and assist urinary flow?
    alpha 1 blockers eg doxazosin
  20. if a patient had painless haematuria and a DVT 3/12 ago and is now on warfarin, what is the cause of his haematuria?
    • bladder cancer - this may have caused the DVT
