It is difficult to identify the narrow sites of the ureter from the outside while carrying out laparoscopic pyeloplasty in patients with ureteropelvic junction obstruction. We developed and named a new method, the Fogarty test, to identify the narrow sites of the ureter using a Fogarty catheter. A 4- to 5- Fr Fogarty catheter was inserted through an incision in the pelvis to the proximal ureter, inflated with air and withdrawn gently to determine resistance. The narrow lumen of the ureter was identified under direct vision and spatulated by laparoscopic scissors. This procedure was carried out repeatedly until the ureter was fully spatulated. By using the Fogarty test, we can visualize the narrow position and length of the ureter under direct vision, and confirm whether it is fully spatulated or not. This technique is very simple and easy to carry out. We believe it is useful for sufficient spatulation of intrinsic ureteral stricture, especially in patients where multiple narrow sites exist.
