catheterFine tube inserted into the body to introduce or remove fluids. The urinary catheter, passed by way of the urethra (the duct that leads urine away from the bladder) was the first to be used. In today's practice, catheters can be inserted into blood vessels, either in the limbs or trunk, to provide blood samples and local pressure measurements, and to deliver drugs and/or nutrients directly into the bloodstream.

| In small case reports and case series where sufficient details were stated, we could find only 11 previously described cases of spinal epidural abscess managed by percutaneous drainage, involving either needle aspiration or catheter drainage and irrigation. We successfully treated this transcervical, transthoracic infection surgically via a transoral approach to the retropharyngeal abscess combined with catheter drainage and irrigation of the abscess cavity at a depth of 13 cm. In uncontrolled trials, urethral stents have provided a less-invasive alternative to catheter drainage for men with outlet obstruction caused by prostatic hypertrophy or cancer (44). |
