Indwelling suprapubic catheters are hollow, flexible tubes inserted into the bladder through a small cut in the abdomen. They are used to drain urine from the bladder and, in the management of bladder dysfunction, are often considered an alternative to a urethral catheter.
Clean intermittent self-catheterisation is preferable to an indwelling urinary catheter; however, if this is not possible, then a indwelling suprapubic catheter is preferable to a urethral catheter for long-term management 1).
