Abstract：
:Because tissue samples obtained ureteroscopically are small, the techniques for biopsy and for handling and processing the samples are crucial. Our aim is to describe the biopsy technique in great detail so other centers can reproduce it. Patients were evaluated by retrograde ureteropyelography and ureteroscopy for diagnosis. The entire collecting system was examined using a combination of small-diameter rigid and flexible ureteroscopes. Samples were retrieved by aspiration, saline lavage, or, when possible, biopsy of visible tumor by a basket or cup forceps. Multiple samples were obtained from all patients. Fresh specimens were hand delivered to the cytopathology laboratory, where they were evaluated with the cytospin technique. A cell block was prepared whenever there was any visible tissue in the sample. Since we have practiced this technique of handling specimens, our ability to diagnose and grade upper tract neoplasms ureteroscopically has improved markedly. Use of this technique can improve the diagnostic accuracy of ureteroscopic biopsy.
