Figure 1: Transrectal ultrasonographic image of the dilated right ureter. Maximum diameter is 2.3 cm. Blue arrow points towards the wall of the ureter.
Figure 2: Endoscopic view of the ureteral polyp protruding from the right ureteral orifice in the bladder. The ureteral orifice is dilated.
Figure 3: Endoscopic view one day postoperative of the base of the polyp inside the ureter. The mucosa is swollen and slightly inflamed. Blue arrow points towards the stalk of the polyp. The ureteral lumen is dilated.
Figure 4: Endoscopic view of the remaining stalk of the polyp (blue arrow) inside the ureter five months postoperative. The surrounding area shows no signs of inflammation. The ureteral lumen is still dilated.
