Background: The ninth most prevalent cancer in women and the fourth most common cancer in men, respectively, is bladder cancer [1]. More than 95% of all bladder cancer cases are caused by transitional cell carcinoma (TCC), the most prevalent histological type [2, 3]. Only 5% of UCs occur in the upper urinary tract (UUT), compared to 95% in the bladder [1]. Renal pelvic tumours are 3–4 times more common than ureteral tumours among all urothelial carcinomas (UC) in the UUT [4]. OBJECTIVES: 1. To evaluate transabdominal USG findings for detection of new cases and recurrence in the follow up of patients with bladder cancer or tumors. 2. To evaluate cystoscopy findings for detection of new cases and recurrence in the follow up of patients with bladder cancer or tumors. 3. To evaluate Comparision of transabdominal USG findings with cystoscopy findings for detection of new cases and recurrence in the follow up of patients with bladder cancer or tumors. Material & Methods: Study Design: A prospective hospital based observational study. Study area: Department of Radio diagnosis, Mamata Academy of Medical Sciences, Bachupally, Hyderabad. Study Period: Dec. 2022 – May 2023. Study population: Subjects attending the Department of Medicine and Urology Department all age group and diagnosed with urinary bladder tumors. Sample size: study consisted of 30 subjects. Study tools and Data collection procedure: The present study includes total of 30 subjects attending the Department of Medicine and Urology Department all age group and diagnosed with urinary bladder tumors. The patients were examined by transabdominal USG and cystoscopy. The demographic details, clinical history were taken as per the detailed prescribed proforma followed by well informed consent from all the study subjects. The present study was conducted after approval from ethical committee. 30 patients clinically suspected to have bladder tumors were investigated by transabdominal ultrasonography. The examination was performed with Siemens acuson X 300 premium edition CH5-2, VF10-5 ultra sound machine. Results: All tumors had a wide area of attachment. 70% of the tumors had irregular out line, 30% smooth out line and 73.33% had heterogenous echotexture, 26.67% uniformly homogenus, 63.33%, 20%, 16.67% frond shaped, flat, and small nodules were present respectively. Ultrasound and cystoscopy was correlated in the aspect of site of involvement 100% in 18 cases at Right postero- lateral, 100 trigones in 6 cases, 100% dome 2cases, 75% of the left postero lateral wall in 12 cases, 50% anterior wall in 2 was accurately demonstrated on ultrasonography. Conclusion: Sensitivity of transabdominal ultrasound for bladder tumors varies from 26% to more than 80% in the literature. Most studies show that transabdominal bladder ultrasound is especially poor in detection of tumors smaller than 5 mm. Another important point is bladder tumor site influences on the ultrasound detection rate. Anterior wall tumors have a lower detection rate because of reverberation artifacts.
