Objective:

We aimed to search for the outcome of the ureteroscopic procedures performed for ureteral stones at our department, and discuss the necessity of intraoperative ureteral stent placement.

Material and Methods:

One hundred and sixtyone cases who underwent ureteroscopic ureterolithotripsy between the years 2004 and 2007 were evaluated in terms of location and size of the stones, pre and postoperative ureteral and calyceal dilatation, use of ureteral stents, and the outcome.

Results:

Our series included 121 males and 40 females whose mean age was 37,4±16,2 years. Eightyfour and 71 of the stones were on the right and left sides respectively whereas 6 patients had bilateral. Stones were located in the lower, middle, and upper part of the ureter in 84, 67, and 10 patients, respectively. Sixtyfive of the cases had proximal dilatation. Stones were ≥10 mm in 63 patients. Ureteral stents were placed in 22 patients due to the ureteral strictures or traumatic procedure. Ureteral stents were not required in 145 cases who did not have above-mentioned indications. A direct urinary system radiograph for residual fragments on the first postoperative day, and an ultrasound for upper tract dilatation on the 15th postoperative day and thirth month were obtained. Of the patients in whom no ureteral stent was placed intraoperatively, 3 needed stents due to severe pain and/or persistent upper tract dilatation (suspicion for obstruction) postoperatively.

Conclusion:

Routine intraoperative ureteral stent use during a ureteroscopic lithotripsy is not required except for traumatic procedures and patients with severe ureteral strictures. This is a cost-effective approach as well.
