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

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.

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.

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].

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