The role of ultrasound in diagnosis and evaluation of bladder tumors

Abstract

Introduction:Bladder tumors are common and the only way to prove it is cystoscopy which is invasive and expensive. Finding noninvasive, well-accepted, and cost-effective method for early detection of bladder cancer is necessary. The aim of this study was to evaluate the role of ultrasonography in the diagnosis and evaluation of bladder tumors.Methods:This study was conducted on 75 patients with indications for cystoscopy. After recording demographic data, ultrasound, and cystoscopy was performed for all patients. Sensitivity and specificity of sonography in the diagnosis of bladder tumors were measured.Results:The most common form of bladder in ultrasound was papillary tumors (86%) and the lowest was related to cystic mass (4%). The sensitivity, specificity, positive predictive value, and negative predictive value of sonography for the diagnosis of bladder tumors were 93.24%, 100%, 100%, and 16.66%, respectively.Conclusion:The results of our study showed that ultrasonography has high sensitivity and specificity in the diagnosis of bladder cancer and since that ultrasound is a noninvasive, well-accepted, and cost-effective diagnostic technique, ultrasound can be performed in suspected patients in the first stage.

Uro-oncology in the era of social distancing: the principles of patient-centered online consultations during the COVID-19 pandemic

“…The authors of this article suggest that while in patients with confirmed low-risk (pTa LG) bladder cancer the follow-up cystoscopy, other than the first one after bladder tumor resection, may be safely postponed for a period of a few months, as even active-surveillance has been reported to be safe in those patients [ 9 , 10 ] and thus delaying a recurrence diagnosis may not actually pose danger, in patients with high risk or unknown risk (primary) disease performing a cystoscopy, if possible to maintain adequate safety standards, is a must. In patients with a suspicion of a primary bladder tumor, an abdominal ultrasound may be considered in place of a cystoscopy, as its sensitivity has been reported to be very high [ 11 ]. Thirdly, as the availability of particular management modalities may be currently limited, the urologist must ascertain that the recommended diagnostic and treatment plan is feasible, for example by postponing currently unavailable imaging testing and substituting it with more accessible work-up.…”

Diagnostic Accuracy of Contrast-Enhanced Ultrasound (CEUS) in the Detection of Muscle-Invasive Bladder Cancer: A Systematic Review and Diagnostic Meta-Analysis

“…Furthermore, CEUS can serve as a noninvasive approach for postoperative follow-up or in high-risk NMIBC patients, suggesting the potential to avoid early repeated resection (Re-TURB) offering valuable imaging information and with consequential socioeconomic implications and impact on health-care-related costs. Second, we would like to emphasize the potential role of CEUS as a first-line approach in patients with hematuria, as conventional US techniques, such as greyscale US and color Doppler ultrasound (CDUS), exhibited limited effectiveness in diagnosing malignant disease [26]. Nonetheless, previous studies concluded that tumor vascularity and lesion size detected by CDUS did not align with tumor stage and histological grade [27].…”

Bladder Cancer during Pregnancy: A Review of the Literature

“…This limitation gave rise to the necessity for alternative diagnostic tools. Ultrasound can be a valuable tool, however it is not always diagnostic, while the option of CT scanning presents a major disadvantage, that is, radiation exposure for pregnant individuals [ 27 , 28 ].…”
