TASK: Your task is to answer biomedical questions using the given abstract. Only output yes, no, or maybe as answer.
INPUT: ['The aim of this investigation was to determine whether postoperative urine colour could be used as a predictor for the presence or absence of a urinary leakage at the vesicourethral anastomosis after open radical prostatectomy.', 'In this prospective study, the urine colour of 223 patients who underwent open radical prostatectomy due to histologically proven localized prostate cancer was assessed macroscopically and microscopically on postoperative day (POD) 6, 7 and 8. All patients underwent evaluation of perianastomotic extravasation by retrograde cystography on POD 8. Baseline characteristics included age; prostate-specific antigen; prostate volume; tumour, node, metastasis classification; and Gleason score.', 'The urine colour was a highly significant predictor for perianastomotic extravasation in cystography when it was red on POD 6, 7 and 8. The sensitivity and specificity of urine colour as a predictor for extravasation were 71.4% and 83.2% on POD 6, 71.4% and 85.8% on POD 7, and 81.8% and 90.9% on POD 8, respectively, with a clear or slightly ensanguined urine colour. The negative and positive predictive values were 98.6% and 81.8%, respectively.'] Does urine colour after radical prostatectomy predict urinary leakage at the vesicourethral anastomosis?
