Urinary Catheterization: Indications, Causes & When It's Necessary

Indications for urinary catheterization:

- Obstructive uropathy: Urinary catheterization is performed to relieve obstruction and promote urine flow in cases of obstructive uropathy, such as benign prostatic hyperplasia (BPH), urethral strictures, and bladder neck contractures.

- Neurogenic bladder: Urinary catheterization may be necessary for individuals with neurogenic bladder, where the nerves that control bladder function are damaged, leading to incomplete bladder emptying.

- Urinary incontinence: In some cases of urinary incontinence, catheterization may be used to manage urine output and prevent leakage.

- Surgery and medical procedures: Urinary catheterization may be required during surgeries that involve the urinary tract or reproductive organs, as well as before, during, and after certain medical procedures.

- Monitoring urine output: Urinary catheterization allows for accurate measurement and monitoring of urine output, which is crucial in critically ill patients and those with fluid imbalances.

- Medication administration: Catheters can be used to administer certain medications directly into the bladder, such as chemotherapy agents or instillation of contrast dye for imaging.

- Bladder retraining: In some cases, urinary catheterization is used as part of bladder retraining programs to help individuals regain control over their bladder function.
