1707: Adjunctive Tamsulosin Improves Stone Free Rate after Ureteroscopic Lithotripsy of Large Renal and Ureteric Calculi: A Prospective Randomized Study

Abstract This study investigated the clinical efficacy of a novel vacuum suction ureteroscopic approach in the treatment of upper ureteral calculi. A total of 160 patients with impacted upper ureteral calculi were included in this study. 50 patients underwent rigid ureteroscopic lithotripsy, 54 patients underwent flexible ureteroscopic lithotripsy, and 56 patients underwent vacuum suction ureteroscopic lithotripsy. The operative time, length of hospitalization, stone-free rate, complication rate and total treatment cost were compared among the three groups. Subgroup analysis was performed based on the stone diameter over and below 1.5 cm. Compared with the other two groups, the vacuum suction ureteroscopy group had higher stone-free rate at 3–5 days (90.0% vs. 61.9% vs. 55.6%, P < 0.05) and 1 month (96.4% vs. 77.7% vs. 74.0%, P < 0.05) postoperatively. In subgroup analysis, the stone-free rate of the vacuum suction ureteroscopy group was significantly higher when the stone diameter was > 1.5 cm at 1 month postoperatively ( P < 0.05); however, there were no differences in postoperative complications.( P > 0.05). In conclusion, the novel vacuum suction ureteroscopic lithotripsy has significantly improved the stone-free rate especially in complicated cases; however the complication and cost was not increased.

Background: Several modalities are available for upper ureteric stone fragmentation. From them pneumatic and holmium: yttrium-aluminum-garnet lithotripsy has favourable outcomes. In this study we studied 50 patients who underwent ureteroscopic pneumatic lithotripsy or laser lithotripsy. This study aims to to compare the outcome of PL and LL in the management of upper ureteric calculi.Methods: This is a prospective, randomized study of 50 cases; 25 cases of TUL with pneumatic lithotripter and 25 cases of TUL with laser lithotripter over two years. The purpose of this study was to analyze the factors predicting the stone-free rate, assess the complications following PL and LL, and assess the need for a second procedure if retropulsion of calculi occurs.Results: Two groups were similar in age, gender, mean size of stones, retropulsion and complications. There was a statistical difference in terms of stone free rate in favour of LL group (p≤0.05) and mean operative time in favor of the PL group (p≤ 0.05). Conclusions: In conclusion, we found that both the PL and LL approaches were effective and safe for upper ureteric calculi, but the LL method had advantages, especially in stone free rate, over the PL treatment. Another advantage of the LL method was safe stone fragmentation in upper ureteral calculi due to lower retropulsion rate in contrast with the PL method.

Objective. To investigate whether the visualization modality (ultrasound or fluoroscopy) used during shockwave lithotripsy (SWL) affects the clinical outcome in those instances where both imaging modalities are optional. Methods. Between November 2014 and July 2016, 114 patients with radiopaque upper urinary tract calculi were randomly assigned to an ultrasound- or fluoroscopy-guided SWL group in a prospective, open-label, single-center study. A standardized SWL protocol was used. The stone-free rate and the positive outcome rate (stone-free or asymptomatic residual fragments ≤ 4 mm) were compared. Results. The stone-free rate was 52% in the ultrasound-guided group compared to 42% in the fluoroscopy-guided group (p = 0.06) and the positive outcome rate was 79% in the ultrasound-guided group compared to 70% in the fluoroscopy-guided group (p = 0.28). These results were not significantly different but proved to be noninferior based on a Wilson confidence interval of independent proportions (noninferiority limit 10%). The mean number of SWL sessions was not significantly different (p = 0.4). Conclusion. Our study demonstrated that the clinical results of ultrasound-guided SWL were not inferior to the results of fluoroscopy-guided SWL, while no ionizing radiation is needed.
