URODYNAMIC STUDY IN DIAGNOSIS OF DIABETIC DYSURIA

Abstract

Treatment of patients with diabetes-induced urinary disturbance requires consideration of many factors, due to wide variations. Attempts were made to classify the patients with diabetic urinary disturbance into subgroups, based on clinical point of views. In 57 patients with diabetic urinary disturbance, the cystourethral function was classified conventionally by using the following indicators: the cystometrographic curve in urodynamic studies, the maximum urethral closure pressure and the functional urethral length. Patients in individual groups were further divided into subgroups, based on the following factors the remaining urinary volume, the curve pattern of urinary flow volume, the degree of incontinentia, the length after appearance of diabetic conditions, and the degree of diabetic neuropathy. Each group of patients was compared, based on the ratio of these factors involved. There was no positive relationship between the cystometrogram curve, the maximum urethral closure pressure, and the functional urethral length. No positive relationship was also observed between the remaining urinary volume as an index for severity of diabetic urinary disturbance, the volume of urinary flow, and the incontinentia. Each index parameter presented in the urodynamic study is not causally related to the length of the appearance of diabetes mellitus. Although the diabetic urinary disturbance is generally considered peripheral due to neuropathy, this study suggests that it is not simply applicable to the classification of diabetic urinary disturbances. The results suggest the diagnosis and treatment of bladder disturbances require understandings of individual bladder and urethral functions based on accurate urodynamic studies.
