Cankurtaran V, et al. - Through a prospective and observational study that recruited 153 citizens, the researchers determined the relationship between diabetic retinopathy (DR) severity and urinary incontinence (UI) in patients with diabetes mellitus (DM). Patients were randomized into three subgroups, according to the severity of DR, as No-DR, nonproliferative DR (NPDR), and proliferative DR (PDR); 40 age-matched healthy subjects constituted the control group. Regarding age, maternal parity, body mass index, type of delivery, menopausal status, and smoking, no marked variation was seen among groups. In comparison to the control group, the mean Urogenital Stress Inventory 6 (UDI-6) urgency UI questions score was significantly greater in the PDR group and in the NPDR group. However, the mean UDI-6 stress UI questions score was alike within groups. The mean UDI-6 voiding difficulty questions score was markedly greater in the PDR group with no marked deviation between other groups. A significantly weaker mean Incontinence Impact Questionnaire score was observed in the PDR group. Also, among glycated hemoglobin level and the UDI-6 urgency UI and voiding difficulty questions and total scores, a modest and positive association was ascertained. Between the duration of DM and all UDI-6 scores, a low and positive relationship was discovered. Hence, in patients with PDR, more critical UI symptoms and their effect on QOL were found.
