Kidney Stones, also known as renal calculi, are hard masses that separate urine from the urinary tract. These stones can occur anywhere in the urinary tract, including the kidneys, bladder, ureters and urethra.
This fluid is called the cerebrospinal fluid (CSF). When it leaks out, the pressure around the brain and spinal cord drops. Causes of leakage through the dura include: 1  Certain head, brain, or spinal surgeries.  Head injury.
Abstract. 1  Urinary tract infection remains an important problem for patients with spinal cord injury. Interventions used to promote bladder emptying and maintain low-pressure voiding have variable risks for urinary tract infection. 2  Urinary tract infection remains the most common infection occurring in patients with spinal cord injury [1â¢]. Renal failure and sepsis secondary to recurrent urinary infection were previously the most common causes of death for these patients, but with advances in voiding management, urinary infection is now an infrequent cause of mortality.
