We report a case of a 35-year male patient with a 100x90 mm mass located at the posterior wall of the urinary bladder just adjacent to the prostate and rectum. The mass caused grade 3 hydronephrosis in the left kidney and grade 1 hydronephrosis in the right kidney. The patient was operated and the mass lesion was excised completely. Because the left ureter was adherent to the mass, it was excised at the most distal part and uretero-neo-cystostomy was performed as the bladder and the prostate were preserved. Morphology and immunohistochemistry were consistent with IMT. With surgical excision of the tumour, no recurrence or metastases were seen up to 3 years postoperatively.en10.29271/jcpsp.2022.JCPSPCR.CR230info:eu-repo/semantics/closedAccessInflammatory myofibroblastic tumourBladderUrinary systemHydronephrosisUrinary-TractBladderArticle32230232Q4WOS:0009436503000442-s2.0-85145429048Q3
