The document defines common abbreviations used in the urinary system. ARF refers to acute renal failure, which is sudden kidney failure from various causes like injury or infection. Cath is shorthand for catheterization, which is inserting a tube into the bladder through the urethra, usually to insert dye or extract urine. GU refers to the genitourinary system, which combines the urinary and reproductive systems. ESWL is a non-invasive procedure using ultrasound to break up stones, and RP is a retrograde pyelogram where dye is inserted via catheter to take x-rays of the kidneys, ureters and bladder.
2. ARF Acute renal failure – sudden failure of the kidney to properly filter waste. Can be caused by physical injury, autoimmune diseases, untreated infections, pregnancy complications, and disorders that result in decreased blood flow.
3. cath Short for catheterization – the insertion of a tube into the bladder through the urethra. It’s purpose is to insert dye into the urinary system (for a cystography, retrograde pyleogram (RP), or VCUG) or to extract urine (when the patient is unable to void or for a urine sample on a patient on complete bedrest).
4. GU Genitourinary – the urinary system is sometimes referred to as the GU system, particularly because the urinary system and male reproductive system share some organs.
5. ESWL Extracorporeal shockwave lithotripsy – a non-invasive procedure that employs ultrasound waves to break up stones in the urinary system.
6. RP Retrograde pyelogram – an x-ray of the KUB (kidneys, ureters, and bladder) after contrast has been inserted via urethral catheterization. Retrograde refers to the flow of the dye because it flows opposite the direction of urine. Usually done to identify defects, outline urinary anatomy before surgery, or while placing ureteral stents.
