title: Assessment of radiotherapy in invasive bladder carcinoma using in vivo methylene blue staining technique.
abstract: In vivo methylene blue staining of the bladder urothelium is a useful method as an adjunct to cystoscopy in detection of recurrent tumors or new ones after radical radiotherapy. The depth of staining correlates well with the grade of bladder tumor differentiation. It is a simple, safe, and acceptable procedure.
