Catheterization of the urinary bladder and suprapubic cystostomy

Repeated catheterization is the preferred method.
If this is not feasible (the patient has an obstruction, urinary output/hour must be monitored, catheterization cannot be performed at home in long-term care, or the patient has considerable retention > 1 000 ml) suprapubic cystostomy is preferred. It is also well suitable for long-term catheterization.
Suprapubic cystostomy is particularly useful for checking that urine production starts to function. It is also easier for the patient than repeated catheterization.
