Chronic or recurrent urinary tract infection (UTI) is a significant pr
oblem for patients with spinal cord lesions (SCL). UTIs are thought to
be a major factor in the development of reduced renal function. To in
vestigate the pathogenesis 151 patients with SCL were included in this
study during a 7 year period. Results of intravenous pyelography and
isotope renography were recorded as well as the bladder emptying metho
ds. One to seven blood samples were obtained from each patient and tes
ted for plasma creatinine, and the presence of precipitating antibodie
s against Escherichia coli, Klebsiella pneumonia, Klebsiella ozaenae,
Proteus mirabilis, Enterococcus faecalis and Pseudomonas aeruginosa. W
e found significant correlation between duration of SCL and precipitat
ing antibodies against urinary tract pathogens (PAU) (r=0.23, P<0.005)
, between plasma creatinine and PAU in patients with spina bifida (r=0
.64, P<0.01), between PAU and the number of positive urine cultures (r
=0.17; P<0.05) and a relation between abnormal urological findings and
PAU. In addition, the PAU was significantly higher in patients with i
ndwelling urethral catheters (P<0.001). Thus it seems that PAU can be
of prognostic value in SCL patients, and PAU might be an indicator for
intensified treatment of recurrent UTI.
