Abstract:
PURPOSE: There has been great demand for indwelling stents for preventing pain, obstructive symptoms and other complications after endoscopic procedures. However, there is no consensus on the placement of a ureteral stent after an ureteroscopy. Inherent stent related problems warrant the minimum possible stenting duration without compromising the results of an ureteroscopy. A prospective randomized trial was performed to evaluate whether 3-day stenting is sufficient for ureteroscopic lithotripsy. MATERIALS AND METHODS: A total of 38 patients underwent an ureteroscopic lithotripsy. There were no severe operative complications. The patients were randomized into 2 groups; Group A: 18 patients who had an internal stent for 3 days after the ureteroscopic lithotripsy, and group B: 20 patients with a stent for 2 weeks. The ureteroscopic lithotripsies were performed with an 8Fr. or 10Fr. ureteroscope, under intravenous propofol anesthesia. Postoperative symptom questionnaires were acquired from each patient. A radiological follow-up was performed at least 4 weeks after the stent removal in all patients. RESULTS: There were no significant differences in the age, sex, stone size or usage of the instrument between the 2 groups. Of the 38 patients, 32 (84%) had discomfort associated with the indwelling stent. The most common symptom was irritative voiding symptom. There were no significant differences in the flank pain and ureteral stricture between the 2 groups. CONCLUSIONS: There was no difference between the 3-days and 2-weeks indwelling stented groups with respect to complications. Therefore, 3 days seems to be a more adequate duration for the decrease stent related complications and symptoms after an ureteroscopic lithotripsy, with no serious intraoperative complications.
