Incidence of upper tract abnormalities in patients with neurovesical dysfunction secondary to multiple sclerosis: analysis of risk factors at initial urologic evaluation.

Abstract：

OBJECTIVES:To determine the incidence of upper tract abnormalities on renal ultrasonography in patients with multiple sclerosis (MS) referred for urologic evaluation, as well as to identify any risk factors present on the basis of the historical information and urodynamic findings. METHODS:Data were derived from all patients with MS referred to the neurourology clinic during a 4-year period. The database was specifically queried for patients found to have upper tract abnormalities on screening renal ultrasonography. Demographic parameters, as well as laboratory values (creatinine) and urodynamic results, were evaluated for risk factors associated with abnormal upper tract findings. RESULTS:Of the 113 patients referred and evaluated, 66 completed both urodynamic testing and renal ultrasonography. Eleven (16.7%) had abnormal ultrasound findings, with focal caliectasis the most common finding. No demographic parameter (age, sex, time since MS diagnosis, MS pattern) was associated with a greater likelihood of abnormal renal ultrasonography on univariate analysis. Neither serum creatinine nor any urodynamic finding (including the presence of dyssynergia or the threshold and amplitude of detrusor overactivity) was associated with abnormal renal ultrasound findings. CONCLUSIONS:No patients in our series had any indication of obstructive uropathy more severe than mild hydronephrosis. Of the 16.7% of patients with any abnormal findings, most were noted to have minor caliectasis, likely to be of little clinical significance. Although no factors identifying patients at risk of renal abnormalities at presentation were found, ongoing evaluation of patients with baseline findings will serve to identify those at risk of progression.
