title: Measurement of the residual urine index in insulin-dependent and non-insulin dependent diabetic men with and without neuropathy.
abstract: Value of the residual urine index was evaluated in 40 individuals both insulin-dependent (IDDM) and non-insulin dependent (NIDDM) diabetic male patients with and without an objective evidence of neuropathy and in 20 age matched non-diabetic men serving as controls using post void bladder ultrasonographic technique. These studies revealed striking results in the neuropathic group. Both IDDM and NIDDM diabetic patients with neuropathy exhibited a significant (P < 0.005) increase in residual-volume in comparison with the controls of the same age group and a direct correlation between residual urine retention and neurogenic bladder was found to be established thus suggesting a generalized massive hypotonia of the bladder in these patients. However, non of the two types of non-neuropathic diabetic patients showed significant difference in the above-mentioned parameters compared to that their respective controls. A non-significant association in the values of the study parameters between insulin dependent and non-insulin dependent diabetic men (with and without neuropathy) was also observed. These findings thus suggest a probable neuropathic involvement in the pathway of urinary tract in both IDDM and NIDDM diabetic men with neuropathy. The greater impairment of the values of residual urine index in these patients may be due to overall greater severity of neuropathy with sympathetic as well as parasympathetic damage irrespective of their type of diabetes.
