Objective: The aim of this prospective single-blinded study was to analyze the stone-free (SF) rates between pneumatic lithotripsy (PL) and laser lithotripsy (LL) for the treatment of single and primary ureteral stones and to evaluate potentially predictive factors of a SF status. Material and Methods: From January 2010 to January 2011, 133 consecutive patients with single and primary ureteral stones were prospectively enrolled. Uni- and multivariate logistic regression were performed to estimate predictive factors of a SF status. Results:The SF rate in the PL group was 80.7 and 86.1% in the LL group (p = 0.002). Success rates with regard of stone position were not significantly different between groups. At univariate logistic regression, middle ureteral stone (OR 3.33, p = 0.04), distal ureteral stone (OR 4.4, p = 0.02), LL (OR 3.05, p = 0.04) and Hounsfield units (HUs) (OR 1.07, p = 0.03) were significantly predictive factors of a SF status. At a multivariate logistic regression, middle ureteral stone (OR 5.58, p =0.01), distal ureteral stone (OR 7.87, p < 0.01), LL (OR 2.4, p = 0.02) and HUs.1,200 (OR 1.15, p = 0.02) were significantly associated with a SF status. Conclusions: LL significantly in- fluences the SF status after ureteroscopy, allowing a higher SF rate when compared to PL. HUs may significantly influence this success rate

Abstract

Objective: The aim of this prospective single-blinded study was to analyze the stone-free (SF) rates between pneumatic lithotripsy (PL) and laser lithotripsy (LL) for the treatment of single and primary ureteral stones and to evaluate potentially predictive factors of a SF status. Material and Methods: From January 2010 to January 2011, 133 consecutive patients with single and primary ureteral stones were prospectively enrolled. Uni- and multivariate logistic regression were performed to estimate predictive factors of a SF status. Results:The SF rate in the PL group was 80.7 and 86.1% in the LL group (p = 0.002). Success rates with regard of stone position were not significantly different between groups. At univariate logistic regression, middle ureteral stone (OR 3.33, p = 0.04), distal ureteral stone (OR 4.4, p = 0.02), LL (OR 3.05, p = 0.04) and Hounsfield units (HUs) (OR 1.07, p = 0.03) were significantly predictive factors of a SF status. At a multivariate logistic regression, middle ureteral stone (OR 5.58, p =0.01), distal ureteral stone (OR 7.87, p < 0.01), LL (OR 2.4, p = 0.02) and HUs.1,200 (OR 1.15, p = 0.02) were significantly associated with a SF status. Conclusions: LL significantly in- fluences the SF status after ureteroscopy, allowing a higher SF rate when compared to PL. HUs may significantly influence this success rate
