PURPOSE: Authors analyzed their experience with urinary bladder tumours. This article discusses clinical and histopathological diagnostics and treatment procedures, and follow up of patients with rare benign urinary bladder tumours. METHODS: 406 patients with bladder tumours were treated in our department between January 2000 and December 2008. 322 patients had superficial tumours and 84 had primary invasive tumours. All patients who underwent transurethral resections of these tumours were operated under general or spinal anaesthesia. The resected specimens were histologically examined in the department of Pathology. RESULTS: 399 of the 406 patients had urothelial bladder cancer, 7 patients had a histologically uncommon type of bladder tumour, one female was diagnosed with sarcomatoid bladder cancer, one patient had a histologically confirmed feochromocytoma of the urinary bladder. Two males had epidermoid carcinoma. One female had a histologically described uncommon benign pseudoneoplastic lesion, chararacteristic for endosalpingiosis. Another two patients were diagnosed with inflammatory myofibroblastic tumour of the urinary bladder. Both patients presented with gross macroscopic haematuria. Authors performed complete transurethral tumour resections, which required several sessions and the deliberation of a blocked ureter through nephrostomy in one case. CONCLUSION: More than 98 % of all treated patients had urothelial bladder cancer in different stages and grades. Two patients had rare benign inflammatory proliferation of the bladder wall which formed large tumorous bleeding masses obstructing the ureter in one case. These types of bladder tumour could be treated conservatively with meticulous long term follow up similarly to patients with bladder cancer (Tab. 1, Fig. 4, Ref. 15). .
