Summary
Bimanual digital palpation demonstrated superior accuracy in staging bladder tumors compared to CT, angiography, and cystography. This finding is crucial for preoperative diagnosis and treatment planning in bladder cancer patients.
Area of Science:
- Urology
- Oncology
- Diagnostic Imaging
Background:
- Accurate preoperative staging of bladder tumors is essential for effective treatment planning.
- Various imaging modalities and clinical examinations are employed for staging, each with limitations.
Purpose of the Study:
- To compare the diagnostic accuracy of computed tomography (CT), pelvic angiography, cystography, and bimanual digital palpation for preoperative staging of bladder tumors.
- To determine the most effective method for clinical staging of bladder cancer.
Main Methods:
- A retrospective analysis of 28 bladder tumor patients staged preoperatively between 1979 and 1982.
- Comparison of preoperative staging (T) with postoperative histopathological staging (pT) for each diagnostic method.
Main Results:
- Diagnostic accuracy rates were: CT (20.0%), pelvic angiography (29.4%), cystography (33.3%), and bimanual digital palpation (47.1%).
- Bimanual digital palpation exhibited the highest diagnostic accuracy among the evaluated methods.
Conclusions:
- Bimanual digital palpation is a valuable and accurate tool for preoperative staging of bladder tumors.
- Clinical examination, specifically digital palpation, should be emphasized in the preoperative assessment of bladder cancer.
