Final answer:
Bladder catheterization may be necessary due to urethral tumors, urinary bladder tumors, and an enlarged prostate gland, which can all impede urine flow. A stricture of the urethra and certain conditions in elderly patients can also necessitate the use of a catheter. This procedure ensures urine drainage when natural pathways are compromised.
Step-by-step explanation:
There are several medically justified reasons for bladder catheterization. Catheterization may be necessary due to urethral tumors, which obstruct the urethra and prevent urine from passing through. A catheter bypasses the obstruction, allowing for urine drainage. Additionally, urinary bladder tumors may also necessitate catheterization for similar reasons, as they can impede the bladder's ability to empty itself. Patients with an enlargement of the prostate gland, especially in conditions such as benign prostatic hypertrophy or prostate cancer, are often unable to empty their bladders fully, making catheterization required to prevent urinary retention and reduce the risk of infection.
Another condition requiring catheterization is a stricture of the urethra, which is a narrowing that restricts urine flow. In such cases, catheterization is a crucial intervention to ensure the bladder can be fully emptied. Moreover, catheterization may be indicated in the presence of neurological conditions or physical challenges seen in some elderly patients, which can impede their ability to urinate. Consistent with our understanding of bladder function and pathology, bladder catheterization is a therapeutic modality employed to facilitate urine drainage when natural pathways are compromised.
