Abstract :

Cancer of the urinary bladder accounts for about 3.2% of all cancers worldwide. After trans –urethral resection of the tumour (TUR) upto 60% –70% of patients develop recurrent disease after the operation and the most common cause of recurrence is the presence of residual tumour mass or presence of any dysplastic urothelium . Our study included 30 random mucosal biopsy specimen of the urothelium adjacent to the tumour mass from patients with previous diagnosis of non invasive papillary urothelial carcinoma.Positive biopsy finding was found in 80% of cases with high grade muscle non invasive bladder cancer while 20 % cases showed normal results .Thus, random mucosal biopsy of normal appeå urothelium that surrounds the tumour can provide a valuable insight into the status of the urothelium and help in preventing recurrences.
