Abstract

Patients with spinal cord injury are prone to the development of bladder calculi. Although bladder stones can by managed effectively, predictive and preventive measures remain a significant challenge for clinicians. We reviewed the medical records of the bladder stone formation group (81 patients) and the control group (153 patients) in the course of follow-up check after spinal cord injury. We analysed the risk factors of the Bladder stone formation including neurologic level and extent (completeness) of injury. method of bladder drainage management, presence of pyuria, specific organisms infecting the urinary tract, urine pH, residual and 24-hour urine volume, serum and 24-hour urine Ca, P, urio acid levels, renal function (BUN/cr./Ccr), and frequency of bladder irrigation. In Was found that most of the patients developing bladder calculi had neurologically complete lesions, indwelling catheters (suprapubic or urethral), large amount of residual urine, high urine pH, pyuria and bacteriuria.
