title: [Can the persistence rate of transurethrally resected bladder tumors be lowered by postoperative instillation of silver nitrate?].
abstract: In 19 out of 88 patients (22%) who had undergone transurethral resection of urothelial carcinoma of the urinary bladder persistent tumours occurred (= tumour detected locally within 3 months). Among 52 patients who had had TUR of urothelial carcinoma and postoperative silver nitrate instillation persistent tumours were found in 11 cases (21%). The persistence rate correlates to the depth of infiltration and the dedifferentiation of the primary tumour. Even in homogenous follow-up groups immediate postoperative instillation of silver nitrate shows no effect on the persistence rate.
