title: [Clinical importance of vesico-renal reflux after transurethral resection of bladder tumors].
abstract: After any resection of tumors near the ostium you have to expect the vesicoureteral reflux as a complication. If the upper urinary tract is primarily normal, this reflux is of no clinical importance (if of course it is diagnosed and controlled). The resection of the ostium, to be radical, can be done without any doubt. The upper urinary tract is rarely hurted. Concerning out patients it is impossible to see how often the tumor spread in the upper urinary tract by the reflux. However, one must consider it, as one of our cases shows.
