AbstractBackground: Ureteral stone is a common disease entity among urolithiasis. Most certain issue of endourological treatment of impacted ureteral stones is the formation of ureteral strictures, with the reporting occurrence rate of 14.2% to 24% of cases.
Materials and Methods: A retrospective study designed including the ureteroscopic treatment for impacted ureteral stones removal. During the follow up period after 3 months, 6 months and 9 months the patients state analysis was done using a regular ultrasound. Following the evaluation using ultrasound, further computed tomography intravenous urogram was done if any signs of hydronephrosis was observed to confirm the occurrence of ureteral strictures.
Results: Among 90 patients included in the study, two of the patients developed ureteral strictures. Hence, the stricture occurrence was 3.3%. Overall assessment of intra- operative risk factors including location of impacted stone, mucosal injury and bleeding revealed that none of these factors contributed significantly to the formation of the ureteric strictures. Stone-related risk factors as stone size, stone impaction site and duration of impaction were considered and did not contribute significantly to the formation of the ureteral strictures.
Conclusions: This retrospective study failed to identify any predictable factors for ureteral stricture formation. It is proposed that patients who developed symptoms undergo a simple postoperative ultrasound screening 3 months, 6 months and 9 months after undergoing endoscopic treatment for impacted ureteral stones.
