Suprapubic catheterization: challenges in changing catheters.

Suprapubic catheterization of the bladder is used as a short- or long-term alternative to urethral catheterization. As with any indwelling urinary catheter, correct insertion, care and removal are vitally important to minimize problems. A particular problem that affects suprapubic catheters is 'cuffing', which on its own or combined with encrustation can potentially cause a great deal of difficulty on removal or discomfort for the patient. This article discusses the causes of cuffing, and suggests using catheters with integral balloons to reduce the incidence of the problem.
