Evaluation of bladder dysfunction in children and adolescents with type 1 diabetes mellitus by uroflowmetry

Abstract

Abstract Objectives Diabetic cystopathy is a condition characterized by decreased bladder sensitivity, increased bladder capacity, decreased bladder contractility and increased residual urine volume. It can also be considered as an early indicator of autonomic dysfunction. In this study, it was aimed to evaluate bladder functions by uroflowmetry in children and adolescents with the diagnosis of type 1 diabetes mellitus. Methods Type 1 diabetes mellitus children and adolescents were applied uroflowmetry and post-void residual urine volumes were evaluated. The physical examination findings of the patients and the laboratory data of diabetes control were obtained from the clinic files. Results A total of 51 cases aged 72–216 (155.6 ± 35.4) months were enrolled into the study. Diabetes age of the cases was 66.5 ± 46.2(13–180) months. The last one year average of HbA1c of the patients was found to be 9.7 ± 1.9%. A total of 9.8% had good, 39.2% moderate and 51% poor metabolic control, respectively. While urodynamic evaluation was normal in 36 (70.6%) of 51 participants, voiding dysfunction was found in 15. There was no statistically significant difference between groups with and without voiding dysfunction in terms of age, gender, duration of diabetes, metabolic control and HbA1c values. Conclusions It is very important to follow up patients with type 1 diabetes mellitus in terms of autonomic dysfunction. Diabetic bladder clinic, which can be observed independently of diabetes duration and metabolic control, is also included in this status. Urodynamic evaluation will be helpful both in demonstrating bladder dysfunction and in preventing possible complications.
