Abstract: Objective　To analyze the influencing factors of urinary leakage in severe stroke patients indwelled with catheters, and to put forward the treatment countermeasures. Methods　By consulting the literatures, the causes of urinary leakage in the patients indwelled with catheters were screened, mainly including the type, material, infection, blockage, and so on. The clinical data of 110 severe stroke patients indwelled with catheters in the neurological intensive care unit of First Hospital, Guangzhou Medical University from January 2018 to December 2020 were collected and statistically analyzed, and the influencing factors of leakage were explored. The measurement data were compared between two groups by t test and between more than two groups by ANOVA, and the univariate analysis was did. Results　Among the 110 patients, 22 had urinary leakage. The univariate analysis showed that there were no statistical differences between the patients with urinary leakage and the patients without urinary leakage in age, education level, gender, type of urinary catheter, amount of air bag injection, and diarrhea (all P > 0.05), and were in length of hospital stay, days of indwelling catheter, constipation, urine sediment, fever, gastric retention, and abdominal distension (all P<0.05). Logistic regression analysis showed that the length of hospital stay, the length of indwelling catheter, constipation, abdominal distention, and urinary sediment were the factors of urinary leakage. Conclusions　The incidence of urinary leakage in severe stroke patients indwelled with urinary catheters is high. We should do a good job in urinary catheter management and strengthen the control and prevention of factors causing urinary leakage, so as to reduce the incidence of urinary leakage.
