Description
OBJECTIVES
To evaluate cognitive trajectories after radical cystectomy and their impact on surgical outcomes, including urinary continence.
METHODS
Ninety patients received cognitive testing using the Mini Mental State Exam (MMSE) before open radical cystectomy as well as 3 days and 2 weeks after surgery. Based on MMSE changes ≥3 points between the three time points, five cognitive trajectories emerged (stable cognition, persistent or transient deterioration or persistent or transient improvement). Surgical outcomes were assessed 90 days, 6 months and 1 year postoperatively.
RESULTS
Mean age was 67.9 ± 9.3 years (range 40 - 88 years). Sixty-six patients (73.3%) had stable cognition, nine patients (10.0%) persistent and seven patients (7.8%) transient deterioration, five patients (5.6%) persistent and three patients (3.3%) transient improvement. An impaired preoperative cognition was the only significant risk factor of short-term cognitive deterioration (OR adjusted for age and sex 9.4, 95%CI 1.6-56.5, p=0.014). Cognition showed no associations with 1-year mortality, 90-day complication rate, cancer progression or duration of in-hospital stay. Patients with transient or persistent cognitive deterioration had an increased risk for nighttime incontinence (OR adjusted for age and sex 5.1, 95%CI 1.1-22.4, p=0.032).
CONCLUSIONS
In this study, the majority of patients showed stable cognition after major abdominopelvic surgery. Cognitive deterioration occurred in a small subgroup of patients, and an impaired preoperative cognition was the only significant risk factor. Postoperative cognitive deterioration was associated with nighttime incontinence.
