ABSTRACT

Objective To evaluate the role and surgical curative effect of the holmium laser under minor-caliber ureteroscope (F4.5) for the treatment of incarcerated ureteral calculus. Methods The holmium laser under minor-caliber ureteroscope (F4.5) was used to treat the incarcerated ureteral calculus with the course more than 2 months in 286 cases (334 sides) . Results 262 patients (304 sides) were successful in operation of single cavity treatment, with success rate of 91.6%. Conclusion Long course incarcerated ureteral calculus often associated with ureteral obstruction lesions (narrow,polyp,granulation hyperplasia,ureter cyst,etc.). Compared with thick ureteroscopy, minor-caliber ureteroscope has high single success rate for the treatment of incarcerated ureteral calculus with high safety, less complications, high gravel and platoon stone rates, and simultaneous treatment of the ureteral obstruction lesions.
