Endoscopic bladder biopsy is performed under general anaesthesia. During surgery, a special device (resectoscope or cold biopsy forceps) is inserted into the bladder through the urethra by the urologist performing the surgery, with which a sample is taken from the suspected area. The surgery ends with haemostasis. After the procedure, a permanent bladder catheter is inserted to possibly rest and rinse the wound.
Tissue samples taken during the procedure will be examined histopathologically.
As with any medical intervention, endoscopic bladder biopsy can have dangers and complications.
During the operation, the bladder wall may be damaged, which will be treated during the operation, or bleeding may occur, which will be quenched by the operator with coagulation (burning).
