- Abstract
Ureteric stricture is a potential complication of impacted ureteric stones. This study investigates surgical and radiological factors that could predict ureteric stricture formation after ureteroscopic treatment of impacted ureteric stones. Intraoperative and radiological data for patients who underwent ureteroscopic treatment of ureteric stones impaction over a 5-year period were reviewed retrospectively. Patients who had previous ureteroscopic treatment or strictures were excluded. Between January 2014 and May 2019, 1,340 patients presented as emergency renal colic secondary to ureteric stones. A total of 297 ureteroscopy procedures were performed for impacted calculi. The mean age was 53 years. The stricture rate was 3.3%. Analysis of radiological and surgical factors revealed that the degree of hydronephrosis, residual fragments and intraoperative ureteric injury were significant predictors for stricture formation (p = 0.018, 0.01 and 0.02, OR = 10, 47 and 1776, respectively). None of the other factors significantly predicted ureteric stricture formation. Our study found the presence of severe hydronephrosis, residual stone fragments after surgery and intraoperative ureteric injury are significant predictive factors for ureteric stricture formation. The high-risk patients should be monitored with routine postoperative renal ultrasound.
