  2. 2. Urinary Catheterization<br />A urinary catheter is a plastic tube most commonly inserted into the patient’s bladder through their urethra in order to drain the bladder. They may be used for the following reasons:<br />Urinary continence – unable to control urination<br />Urinary retention – unable to release urine in bladder<br />Used during and after surgery<br />Medical conditions – i.e. multiple sclerosis and dementia<br />
  3. 3. Urinary Catheterization<br />Main types of catheters<br /><ul><li>Indwelling catheter
  4. 4. Characteristic of a balloon inflated at the end in order to stay in place of the urethra or bladder and the other end is attached to a drainage bag. The balloon is deflated when removal is needed.

  7. 7. Intermittent Catheter
  8. 8. Common for short term use. Does not have a balloon to keep it in place. It is constantly aided by the nurse and removed once the flow of urine has stopped.</li></li></ul><li>Cystography<br />Use of a catheter to insert dyes into the urethra. This is done for X-ray purposes in order to study the bladder for any infections, tumors or stones.<br />The procedure entails injecting the dye until the bladder is full. An X-ray is taken while bladder is full and when bladder is empty.<br />
  9. 9. Chronic Renal Failure<br />Chronic Renal Failure is the slow and gradual loss of kidney function.<br />Most often occurred during other illnesses, but is also caused by high blood pressure and diabetes.<br />Kidney dialysis or kidney transplant will most likely be needed<br />

  14. 14. Extracorpeal shockwave lithotripsy<br />The procedure is usually outpatient surgery and may require a stint to hold the urethra open to allow the small stones to pass. <br />Many patients will experience passing of stone fragments and mild pain for a few days after the procedure.<br />
