Introduction and Aim: Malignant non-urothelial tumours of the urinary bladder are rare. They present less than 5 % of
all urinary bladder neoplasms. The goal of the work is to state results of diagnostics and treatment of these tumours.
Material and Methods: Retrospectively, we analysed patients with diagnosed non-urothelial tumour of the urinary bladder
in the period of last five years. The non-urothelial tumour was diagnosed in nine patients with the average age of
67.5 years (scope 52-86 years), out of them seven men and two women. Macroscopic haematuria was the most frequent
manifestation of the clinical disease. Non-urothelial tumours were diagnosed from bioptic material obtained by
trans-urethral resection. Adenocarcinoma was diagnosed in four patients, while in three cases it was the urachal subtype
of carcinoma, in one case adenocarcinoma arising from the laterodorsal wall of the urinary bladder, small-cell carcinoma
was diagnosed in three patients and two leiomyosarcomas. Radical cystectomy was performed in six patients
and partial resection of the urinary bladder in three patients with urachal carcinoma. Five patients out of nine are surviving,
two of them with urachal carcinoma survive 12 and 5 months, with non-urethral adenocarcinoma 1 month, with
small-cell carcinoma 25 months and with leiomyosarcoma 32 months. Two patients with small-cell carcinoma exited
because of the disease progression 9 and 1 month after the operation, one patient with urachal adenocarcinoma after
10 months and one patient with leiomyosarcoma 1 months after the operation
Conclusion: Radical surgical treatment with cystectomy or partial resection of the urinary bladder in patients with urachal
adenocarcinoma is a basic treatment of non-urothelial tumours in the urinary bladder. The role of adjuvant or neoadjuvant
treatment is not clearly defined.
