Study on Measurement Information of Bladder Tumor Measurement Based on Ultrasound Imaging Measurement Technology (Preprint)

Abstract

Background: Bladder cancer has the highest incidence of urinary tract tumours. At present, early clinical diagnosis of bladder cancer is receiving more and more attention. Ultrasound is currently one of the most meaningful methods for early screening of bladder cancer.

Objective: The objective is to evaluate the sensitivity and specificity of ultrasonography and cystoscopy in the diagnosis and detection of bladder tumors, as well as the detection rate of tumors in different number, location, and size.

Methods: In this study, we evaluated the sensitivity and specificity of ultrasound and cystoscopy in the diagnosis and detection of bladder tumours, and the detection rate of tumours in different numbers, locations, and sizes. Value. The paper retrospectively analysed 163 patients who underwent transurethral resection of bladder tumours in our hospital from June 2015 to December 2018 due to bladder tumours. Postoperative pathology of all patients were bladder urothelial tumours. All patients underwent bladder ultrasound and cystoscopy.

Results: The coincidence rate of colour Doppler ultrasound and cystoscopy in the diagnosis of single or multiple bladder tumours was found, and the results were not statistically different (P value> 0.05). For bladder tumours with a maximum diameter of> 10 mm, there was no statistically significant difference in diagnostic coincidence between colour Doppler ultrasound and cystoscopy (P value> 0.05). For bladder tumours with a maximum diameter of <10 mm, the diagnostic coincidence rate of cystoscopy was 92.68% (38/41), and the coincidence rate of transabdominal ultrasound was 70.73% (29/41). There was a statistical difference between cystoscopy and colour Doppler ultrasound (P Value <0.05).

Conclusions: The sensitivity and specificity of color Doppler ultrasound to bladder tumor were lower than that of cystoscopy. There was no significant difference in the coincidence rate between colour Doppler ultrasound and cystoscopy in the diagnosis of single or multiple tumours. For tumours located in the bladder neck, the coincidence rate of colour Doppler ultrasound is better than cystoscopy.
