Objective:
To investigate the urodynamic risk factors and prognosis of post-stroke urinary incontinence (PSUI).
Methods:
The data from 100 stroke patients admitted to our hospital from January 2019 to March 2025 were retrospectively analyzed. According to whether urinary incontinence occurred after treatment, they were divided into urinary incontinence and normal groups, including 42 cases in the urinary incontinence group and 58 cases in the normal group. The general data and treatment-related indicators of the two groups were compared. Univariate and multivariate analysis were used to analyze the influencing factors of urinary incontinence after stroke and establish a predictive model. Finally, the short-term prognosis and influencing factors for patients with urinary incontinence were analyzed.
Results:
The average age, hematoma size and National Institutes of Health Stroke Scale (NIHSS) score of patients in the urinary incontinence group were significantly higher than those of the normal group. The lesion site analysis showed that the frontal lobe involvement rate was 59.5% in the incontinence group and 25.9% in the control group. The rate of thalamic involvement was 47.6% in the study group and 19.0% in the control group. The incidences of aphasia, cerebral hemorrhage, multiple stroke, female sex and diabetes were higher in the incontinence group. Multivariate analysis identified the following independent risk factors for PSUI: NIHSS score, female sex, frontal lobe lesions, thalamic lesionsand diabetes. The predictive model worked well incorporating these factors.
Conclusion:
The occurrence of urinary incontinence after stroke was related to the baseline data of patients. Among them, NIHSS score, female sex, frontal and thalamic lesions, and diabetes were influencing factorsfor urinary incontinence after stroke in patients, while NIHSS score, female sex, and diabetes were influencing factors for urinary incontinence persistence. In clinical practice, targeted intervention should be carried out in combination with patient data to reduce the incidence of urinary incontinence after stroke.

01:13Introduction to Urinary System
The kidneys are bean-shaped organs located in the retroperitoneal space, on either side of the vertebral column, between the T12 and L3 vertebrae. They are partially protected by the rib cage and surrounded by perirenal fat, which provides cushioning. They are responsible for urine formation and play critical roles in regulating blood pressure, electrolyte levels, and hormone production. The ureters...

In males, the bladder is situated in front of the rectum, while in females, it is positioned anterior to the vagina and uterus. The bladder floor contains an inverted triangular area called the trigone, defined by the two ureteric...
