title: Starch granulomas after transurethral resection of bladder tumors.
abstract: Starch granulomas have been observed in 3 patients in a series of 140 under treatment for bladder cancer during the period 1949 to 1969 in one hospital. The lesions were observed at the fourth or subsequent transurethral procedure, suggesting strongly that the starch had been introduced at a previous transurethral procedure. The granulomatous reaction may simulate a recurrence of the initial bladder tumor.
