What is one of the potential noninfectious harms of catheter use?

Mechanical trauma to urethral structures is a significant concern with catheter use. When a catheter is inserted into the urinary tract, it can cause irritation or injury to the urethra. This trauma may result from the catheter's material, size, or movement, as well as from improper technique during insertion or care. Such injuries can lead to long-term complications, including strictures or blockage of urine flow, which can cause further discomfort and necessitate additional medical interventions. Recognizing mechanical trauma as a potential harm underscores the importance of using catheters judiciously and following best practices in catheter care and maintenance to minimize risks to patients.

Urinary retention, the increased risk of infection, and elevated blood pressure are all relevant clinical issues but do not fit within the framework of noninfectious harms directly associated with catheter use.
