It may be used for diagnostic purposes, such as collection of an uncontaminated urine specimen for culture and urinalysis, when it is essential to obtain a urine specimen from a young child who cannot void on command. Urethral catheterization also may be performed to carry out voiding cystourethrography or to monitor urine output in certain postoperative patients or very ill patients. Therapeutic indications include decompression of acute urinary retention, intermittent catheterization of neurogenic bladder.
