The applicability of using straight ureteral stents for the treatment of ureteral stones in presumably non-compliant patients.

There have been many reports describing the complications of retained ureteral stents following stone treatment. We wanted to evaluate the practicality of definitive treatment of poorly compliant patients who present with ureteral stones using a straight stent connected to a urethral catheter alone and compared these to patients treated with double-J stents alone. We treated 23 patients (12 in group I and 11 patients in group II) who had a ureteral stone of 6 mm or less, with an indwelling straight stent and a double-J stent, respectively, while on oral antibiotics. We followed these patients 1 week later with an abdominal X-ray prior to removing the stent. Eleven patients in group I and 9 patients in group II passed their stones spontaneously. Three patients required surgical intervention with a ureterscope and laser lithotripsy. There were no cases of infection or pyelonephritis. Although each of the straight-stent-treated patients returned to our clinic for follow-up, only 5 of the 11 double-J stent patients returned for follow-up. The remaining 6 patients had to be contacted to remind them that they still had an internal stent. Although technologic advances now allow many urologists to definitively treat ureteral stones, some urologists may lack the proper equipment and/or assistance to treat the stone at the time of presentation, or may deal with non-compliant patients. Therefore, in these certain circumstances, treatment of small ureteral stones in non-compliant patients using a straight stent connected to a leg bag, as either definitive or initial treatment, may be of practical use and avoid the risk of retained double-J ureteral stents.
