Abstract Background Identifying the precise location of the lower ureter is crucial in not only ureteral surgeries but also the other surgeries that may cause ureteral injury. Although a variety of approaches have been applied to detect the location of the lower ureter, the majority of them had an association with several complications or be difficult to perform perfectly or be time-consuming. Case presentation Seven patients with distal ureteric stones of the size ranged from 2 to 3 cm. All patients entered the study after signing the informed consent, and the case report is based on CARE guidelines. After specifying the inner ring of the inguinal canal, the posterior peritoneum was opened and dissected from an area of 2 cm medial and 2 cm inferior to the inner ring. Thereafter, the stone was extracted from the precise location of them, which was identified by ureteral pinching. Conclusion We assumed that we were easily able to identify the site of the lower ureter through 2 cm medial and 2 cm inferior to the inner ring. The result of our study on seven patients demonstrated that this maneuver can minimize the time of surgery and no complications have been seen while this approach was applied.
