Value of Geriatric Assessment Using the G8 to Predict Postoperative Urinary Tract Infections in Patients Undergoing Radical Cystectomy.

Objective: Urinary tract infection is one of the most common and distressing complications of radical cystectomy with urinary diversion. This study aimed to elucidate the usefulness of the geriatric-8 screening tool for predicting postoperative complications, especially urinary tract infections, in patients who underwent radical cystectomy with urinary diversion.

Material And Methods: Ninety-one patients with bladder cancer who underwent radical cystectomy with urinary diversion were assessed for geriatric-8 and classified into 3 groups according to their geriatric-8 score: 14 as the high score group. We retrospectively analyzed the association between geriatric-8 score and postoperative complications classified according to the Clavien-Dindo classification.

Results: The median age of the patients was 75 years (interquartile range 71-80 years) and 75 (82%) were male; 41 of the patients (45%) had high geriatric-8 score (>14), 40 of the patients (44%) had intermediate geriatric-8 score (11-14), and 10 of the patients (11%) had low geriatric-8 score (< 11). In multivariate analysis, low score of geriatric-8 was independently associated with the occurrence of grade 2 or higher urinary tract infection within 30 days [odds ratio=5.9; 95% CI=1.2-30.3; P=.03], along with female [odds ratio=6.1; 95% CI=1.7-21.7; P=.006] and open surgery [odds ratio=6.0; 95% CI=1.8-19.6; P=.003].

Conclusion: The geriatric-8 score may contribute to predict postoperative urinary tract infection in patients with bladder cancer who underwent radical cystectomy with urinary diversion.
