Background: Bladder tumour is a leading type of urinary tract malignancy after the prostate. This study was carried out to analyse the pathological and ultrasonographic features of urinary bladder tumours.
Method: Ninety six consecutive patients were reviewed prospectively between, September 2004 and December 2007. The location, size, multiplicity, shape, surface, and presence of calcification of the bladder
tumour as well as the pathological types were described.
Results: There were 5 cases of multicentric tumours. Tumour size ranged from 24 mm to 113 mm (mean = 59.6 ±19 mm.The tumour involves the bladder base (31.3%), right anterolateral wall (26l.8%) and left
anterolateral wall (17.7%). The posterior and anterior wall involvements were (12.5% and (4.2%) respectively, while lateral and right posterior lateral had (1.0%) and 7.3%, respectively. Calcified foci are seen in 7(7.3%) of the bladder masses.The bladder mass surfaces was regular 5(5.2%) and irregular in 67 (69.5%) of the masses, and sessile/polypoidal in 2 (2.1%). Pathologically, squamous cell carcinoma(59.0%) outnumbered transitional cell carcinoma(27.3%) .
Conclusion: Most bladder tumours were single, arising from the bladder base and of squcmous cell type on histology
