Cystocentesis is defined as what?

• A. Sterile collection of urine by puncturing the bladder with a needle & aspirating urine
• B. Non-sterile collection through free catch
• C. Surgical removal of the bladder
• D. Urine collection by catheterization

Answer: (A)

Cystocentesis is the sterile collection of urine by puncturing the bladder with a needle and aspirating the urine. This approach yields a sample free from contamination by the distal urinary tract or genital flora, making it ideal when a sterile urine culture or precise diagnostic testing is needed. Non-sterile free catch can be contaminated by urethral or vaginal bacteria; catheterization introduces bacteria from the urethra or genital tract and is not as clean for culture in some cases; surgical removal of the bladder is an invasive procedure that defeats the purpose of urine collection.
