Introduction: Lower urinary tract dysfunctions secondary to type 2 DM are common, chronic and costly disorders. The incidence of diabetic bladder dysfunction was estimated range between 43% and 87% for type 1 and 25% for type 2 diabetes. Ultrasonography is an easy-to-use, fast, safe, non-invasive, painless, pleasant and valuable method of assessing Bladder Post-Void Residual Volume (PVR).
Aim: To investigate prevalence of bladder dysfunction and its relation with risk factors, clinical features of diabetic cystopathy in women with diabetes, to identify the values predicting to have postvoid residual volume of the risk factors.
Methods: A cross sectional descriptive study, a cohort of 84 female inpatients and outpatients with diabetes mellitus who were treated at Hue University of Medicine and Pharmacy Hospital from 08/2017 to 08/2019 and 84 healthy control subjects were enrolled, the patients were carried out clinical finding, taken blood tests, and estimated postvoid residual volume using 2D ultrasound.
Results: the postvoid residual volume was presented in 67 cases (79.80%), the clinical symptoms of diabetic cystopathy were reported in 75% of women with diabetes. Blood glucose, HbA1c, clinical symptoms of diabetic cystopathy, postural hypotension and diabetic peripheral neuropathy were associated with postvoid residual volume. The HbA1c level had a great capability to predict who had postvoid residual volume, at HbA1c cutoff value of 9.1%, Se 65.67%, Sp 94.12%, AUC 0.811, p < 0.001. Conclusion: Bladder dysfunction made up a highly prevalent in women with poor glycemic control.
Key words: bladder dysfunction, diabetic cystopathy, bladder postvoid residual volume (PVR)
