Analysis of the risk factors of upper urinary tract dilatation due to spinal cord injury / 中华外科杂志

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the urodynamic risk factors of upper urinary tract dilatation (UUTD) secondary to spinal cord injury (SCI).</p><p><b>METHODS</b>Ninety-six SCI patients of Tangshan earthquake were divided into 2 groups by ultrasonography 16 SCI patients (group A) with UUTD and 80 SCI patients (group B) without UUTD received urodynamic test. Responses were evaluated using single and multiple analysis after examination.</p><p><b>RESULTS</b>The incidence of male was significantly higher than that of female. Residual urine volume, maximum cystometric capacity, detrusor leak point pressure and the incidence of bladder low compliance in group A were significantly higher than those in group B. There were no significant differences in age, the incidence of detrusor hyperreflexia, relative safe bladder capacity, the incidence of detrusor-sphincter dyssynergia, maximum flow rate and maximum urethral closure pressure between 2 groups. Bladder low compliance was cardinal risk factors according to Logistic regression analysis.</p><p><b>CONCLUSION</b>An early urodynamic examination and treatment for SCI patients are important to prevent from bladder low compliance and upper urinary tract damage.</p>
