What is cystocentesis?

• A. Drawing of a sterile urine sample by inserting a hypodermic needle into the bladder
• B. Flushing the catheter with an anticoagulant solution
• C. Cannulation of a teat
• D. Infection of a cannulated area

Answer: (A)

Cystocentesis is the procedure of obtaining a urine sample by inserting a sterile needle directly into the bladder through the abdominal wall. The aim is to collect urine that is not contaminated by bacteria from the urethra or genital tract, which is especially important when you need an accurate culture and sensitivity result or a clean urinalysis. The technique relies on aseptic prep, proper restraint and positioning, and careful needle placement into a distended bladder to aspirate urine. After collection, a little pressure at the puncture site helps prevent leakage, and the animal is monitored for any signs of discomfort or complications. While rare, potential risks include bladder puncture of surrounding structures, bleeding, or bladder rupture, so this should be performed by someone trained. This option is distinct from flushing a catheter with an anticoagulant solution, which is not how a sterile urine sample is obtained; teat cannulation relates to the mammary gland, and infection of a cannulated area describes a complication rather than a method for collecting urine.
