Ureteroscopic management of lower ureteric calculi: a 15-year single-centre experience.

Objective: To review our 15-year experience with ureteroscopic treatment of distal ureteric calculi and to determine the impact of improved technology and techniques on the efficacy, success and complications of the procedure.

Patients And Methods: We retrospectively reviewed the medical records of 4512 patients who underwent 5133 ureteroscopic procedures for the treatment of distal ureteric calculi at our institution from January 1991 to December 2005. The patient and stone characteristics, treatment variables and clinical outcomes were assessed.
