Two patients with large volume disease in markedly dilated ureters were treated endoscopically by wide dilation of the ureteral orifice and passage of larger nonureteroscopic endoscopes. The larger instruments provided better vision and the ability to work with larger tools, which greatly facilitated treatment without complication in patients who otherwise would have undergone an open procedure.
