English Abstract:

  【Abstract】 Objective：To investigate the influence of bladder management on urinary stone formation in patients with spinal cord injury（SCI）.Method：From June 2005 to June 2010，337 cases with voiding dysfunction after spinal cord injury were included in this series.Bladder management before admission included bladder stoma in 47 cases，regular replacement of indwelling catheter in 51 cases，triggered reflex voiding in 29 cases，voiding by abdominal straining in 31 cases，condom catheters with urine collection devices in 35 cases，intermittent catheterization in 144 cases.All patients accepted ultrasound examination of urinary system，urine routine examination，urine bacterial culture and video urodynamics examination.Result：A total of 128 SCI cases were complicated with urinary calculi，including bladder stoma in 32 cases，regular replacement of indwelling catheter in 34 cases，triggered reflex voiding in 19 cases，voiding by abdominal straining in 11 cases，condom catheters with urine collection devices in 20 cases，intermittent catheterization in 12 cases.Intermittent catheterization had the lowest incidence of urinary stones formation compared with the other means（P<0.05）.In 128 patients with urinary calculi，120 patients presented with urinary tract infection and abnormal video urodynamics.Conclusion：Bladder management after spinal cord injury has major impact on urinary stones formation. Intermittent catheterization can decrease the incidence of urinary stones.
