  1. Urinary Tract Radiological Investigations and Anatomy MEDICAL IMAGING & RADIOLOGY DEPARTMENT

  2. IMAGING MODALITIES • IONIZING RADIATION Conventional (plain) radiography. Contrast studies (X-Ray + Contrast) Computed Tomography. Isotopic scan Angiography • NONIONIZING RADIATION US. MRI. • Intravenous urography • Cysto-urethography • Antegrade pyelography • Retrograde pyelography • Hysterosalpingography

  3. KUB Conventional plain film of the abdomen is called a KUB (Kidneys, Ureters, Bladder) KIDNEYS URETERS URINARY BLADDER URETHRA Good evaluation of radio-opaque stones

  4. IVU KUB IVU This is KUB taken post intravenous contrast injection

  5. IVU • Also called IVP (intravenous pyelogram) • Demonstrates both function and structure of the renal system • Function --- Filtration • Structure --- Contrast filled collecting system This is KUB taken post intravenous contrast injection • Indications: • Urolithiasis / calculus • Pyelonephritis • Hydronephrosis • Trauma • Tumour • Renal hypertension • Congenital abnormality • Contra-Indications: (relative) • History of Allergy • Asthma • Cardiovascular disease • Sickle cell disease • Diabetes mellitus

  6. IVU This is KUB taken post intravenous contrast injection Renal Pelvis • After IV injection, sequential images are taken in time order. • Immediate post IV • 5 min post IV • 10 min post IV Left Ureter Urinary Bladder

  7. IVU • Immediate post IV is nephrogram This is KUB taken post intravenous contrast injection Left Kidney Right Kidney

  8. IVU • 5 min post IV is nephrogram This is KUB taken post intravenous contrast injection

  9. IVU • 10 min post IV is nephrogram This is KUB taken post intravenous contrast injection Renal Pelvis Left Ureter Full Bladder 20 min Urinary Bladder

  10. Kidney Renal fascia Hilum Renal sinus Renal cortex Renal columns Renal medulla Renal pyramids Calyces Minor calyces Major calyces Renal pelvis
