This is a concise pocket guide to urological investigative procedures. It reviews the indications and pitfalls of tests before they are requested and suggests which investigations should be performed in individual urological conditions. Cross-sectional and other radiological images help illustrate the main diagnostic features, and diagrams and graphs illustrate the main points of the test. Bulleted items at the end of chapters are highlighted in a 'box' - useful during a busy ward round, out-patient clinic, or for last-minute consultation prior a viva examination.
