This concise pocket guide to urological investigative procedures reviews the indications and pitfalls of tests before they are requested and suggests which tests should be performed in individual urological conditions. Part I describes the principles, methodology, advantages and disadvantages of each of the investigations and covers all urological investigations/tests. Part II gives advice on the choice of investigations for individual urological conditions. For each investigation in Part I and urological condition in Part II, important bullet points are highlighted in a ‘box’ – useful during a busy ward round, out-patient clinic, or for last-minute consultation prior a viva examination. This comprehensive yet user-friendly handbook will be useful for medical students and residents in urology, as well as a solid review for already-practicing urologists.
