Foley Catheter
A catheter that is placed through the urethra and regained in urinary bladder by a balloon that is inflated with air or fluid
Horseshoe Kidney
A condition in which the lower poles of the kidney are joined across midline by a band of soft tissue, resulting in a rotation anomaly on one or both sides

D. Renal failure
Supernumerary kidney
A relatively rare anomaly consisting of the presence of a third, small rudimentary kidney
Suprapubic catheter
A urinary catheter that is placed into the urinary bladder through the skin in the suprapubic area to allow drainage of urine

- The amount of urine formed in a typical day is about 1 to 1.5 L.
- Urine is formed and excreted in the nephron, the microscopic unit of the kidney.
