Routine radiologic surveillance for obstruction is not required in asymptomatic patients after ureteroscopy.

Objective: A retrospective medical record review was performed with the goal of determining the need for radiologic evaluation after ureteroscopy.

Patients And Methods: Of 183 patients undergoing ureteroscopic procedures at our institution between 1989 and 1993, 131 underwent postoperative radiologic studies capable of diagnosing ureteral obstruction. Of these patients, 110 (84%) were asymptomatic after the procedure, and radiologic procedures capable of displaying obstruction were performed at a median of 60 days (mean 73 days; standard deviation 189 days) after ureteroscopy.
