Is it useful to perform biopsy at flexible cystoscopy? Study throws light
Ireland: A recent study in the Irish Journal of Medical Science sheds light on whether it is worthwhile to perform a biopsy at flexible cystoscopy for diagnosis and surveillance of bladder carcinoma. According to the study, about 18% of biopsies helped in malignancy detection, small volumes of tissue are collected at flexible cystoscopy, these can help to distinguish malignancy from benign pathology.
Flexible cystoscopy is the standard procedure for the surveillance and diagnosis of bladder carcinoma. Most flexible cystoscopes having a working channel that allows for biopsy and diathermy -- in case a suspicious lesion is observed. Only small instruments are permitted in the working channel that limits the volume of material retrieved for historical analysis. There are no standards of quality control of biopsy specimens taken at flexible cystoscopy.
