[Predictors of catheter-related bladder discomfort]
Insights
Catheter Related Bladder Discomfort (CRBD) affects over half of patients, often appearing on day one. Key risk factors include larger catheter caliber, lack of lubrication, and prior catheterization history.
Area of Science:
- Urology
- Patient Outcomes
- Epidemiology
Background:
- Catheter Related Bladder Discomfort (CRBD) is a common complication.
- Understanding CRBD's epidemiological profile and predictive factors is crucial for patient care.
Purpose of the Study:
- To describe the epidemiology of CRBD.
- To identify factors predicting CRBD occurrence.
Main Methods:
- A cohort of 300 patients undergoing urinary catheterization was evaluated.
- Data collected included patient demographics, catheter details, and CRBD presence.
- Statistical analyses (univariate and multivariate) identified risk factors.
Main Results:
- 54% of patients experienced CRBD, predominantly within the first day.
- Significant risk factors identified were: catheter caliber ≥18 Fr, no lubrication, laparotomy, age <50, Cesarean delivery, and prior catheterization history.
- Average catheterization duration was 2.5 days.
Conclusions:
- Several factors contribute to CRBD development.
- Healthcare providers should focus on mitigating identified risk factors, especially technical aspects, to prevent CRBD.
Introduction:
Establish a descriptive epidemiological profile of patients with Catheter Related Bladder Discomfort (CRBD) and identify its predictive factors.
Material And Method:
Between June 2019 and December 2019, 300 patients have been evaluated. Different parameters were taken into account including: sex, age, body mass index (BMI), historical health data, duration and indications of the urinary catheterization, type of the transurethral catheter used, lubrication of the catheter and the existence of CRBD. We grouped our patients according to the intensity of CRBD syndrome. The various factors likely to be correlated with the occurrence of CRBD were subject of a univariate then multivariate analysis.
Results:
300 patients were included. The average age was 49 years (133 men and 167 women). 68 patients (22.6%) had history of urinary catheterization. 19% of patients were catheterized for acute urinary retention, while 81% were catheterized before surgery. The average duration of the urinary catheterization was 2.5 days. 54% showed CRBD symptoms, including more than 92% on the first day of the urinary catheterization. The significant risk factors in multivariate analysis were: the caliber of the catheter ≥18 Fr, the absence of lubrication, laparotomy, age <50 years, Cesarean and urinary catheterization medical history.
Conclusion:
This study identified various factors incriminated in the occurrence of CRBD. The role of the hospital practitioner is to prevent this syndrome by reducing predictive factors, particularly the technical ones.
