Background: Bladder cancer is one of the most frequent type of urinary cancer which has been ever increasing. For the better treatment, the early discovery and definite diagnosis of this disease played an important role. Objective: To describe some clinical symptoms and ultrasound features of tumorlike lesions of the bladder. To diagnose and classify the histopathology of tumorlike lesions of the bladder.
Materials, method: cross - sectional study on 64 cases in Hue University Hospital and Hue central hospital from April, 2016 to February, 2017.
Results: Hematuria was the most common reason that patients went to hospital (79.7%). Lower abdominal pain and irritation during urination accounting for 9.4% and 6.2% respectively. Only 3 patients with bladder cancer were accidentally discovered through periodic health examination (4.7%). The characteristics of hematuria in bladder tumor was flesh red urine (62.5%) and total hematuria (60.7%). With ultrasonography, the results of 64 patients were divided in 3 groups as follow: bladder tumor, which was the highest rate 87.5%, bladder polyp was 3.1% and focal bladder wall thickening was 9.4%. Of which, the vast majority of these ultrasound images was tumor - like lesions protruding in the lumen of the bladder (75%), the rest was wall thickening lesions (25%). Tumors were different in size, the biggest tumor was 7cm in diameter and the smallest was 0.6cm. Those with the diameter 3cm or bigger accounting for 42.2%, the smaller was 57.8%. Most cases have only one lesion (62.5%) and at lateral wall (46.6%). Histopathologically, cancer was 59/64 case (92.2%): urothelial carcinoma was 98.3 %, squamous cell carcinomawas 1.7% and 5 cases (7.8%) were benign. Most cancerous cases were poorly differentiated, grade II (50.9%) and grade III (32.2%). The stage T1NxMx was 20.3% and worse than T2MxNx was 79.7%.
Conclusion: hematuria was the most popular symptom, suggesting bladder cancer. Clinical diagnosing bladder cancer was not high sensitive (61.01%). Ultrasound could detect bladder tumor with high sensitive (89.8%). These patients also needed histopathology classification to diagnose and finally choose the best method for the appropriate treatment.
