Analysis of Risk Factors for Poor Drainage of Ureteral Stents after Radical Cystectomy with Cutaneous Ureterostomy: A Retrospective Study

Le résumé fourni par la source

Objective: Currently, the factors influencing poor drainage of ureteral stents after radical cystectomy with cutaneous ureterostomy are still unclear. Therefore, the aim of this study was to determine the risk factors for poor drainage of ureteral stents after radical cystectomy with cutaneous ureterostomy and to provide evidence for the prevention of this complication. Methods: This retrospective study included 86 patients who underwent periodic replacement of ureteral stents following radical cystectomy with cutaneous ureterostomy between October 2017 and March 2024. The general data and related indicators of the patients were collected, the risk factors were identified through univariate and multivariate logistic regression analyses, and corresponding interventions were proposed. Results: Among the 86 patients, 26 had poor drainage of ureteral stents, with an incidence rate of 30.23%, and no serious consequences occurred after timely and effective treatment. Univariate and multivariate logistic regression analyses revealed that body mass index (BMI) (p = 0.003, odds ratio (OR) = 2.909, 95% CI: 1.435–5.898), diabetes mellitus (p = 0.012, OR = 14.073, 95% CI: 1.770–111.889), urinary tract infection (p = 0.004, OR = 16.792, 95% CI: 2.402–117.411), and foreign body blockage (p = 0.048, OR = 5.277, 95% CI: 1.012–27.512) were independent risk factors for poor drainage of ureteral stents. Conclusions: The incidence of poor drainage of ureteral stents after radical cystectomy with cutaneous ureterostomy is relatively high. Maintenance of a healthy weight, strict management of blood glucose levels, active prevention of urinary tract infections, and timely detection and removal of small foreign bodies that may be present are essential to prevent this complication.
