TL;DR: In this article, the authors determined whether the interval between diagnosis of muscle invasion and definitive radical cystectomy influenced pathological staging outcome and found that those patients with an interval greater than 90 days were more likely to have pT3 or higher, non-organ confined disease compared to those patients undergoing cystect before 90 days (81% versus 52%, p 0.01).
