ABSTRACT
Objective The aim of this study was to compared the clinical effect of ureteroscopic holmium laser incision (USHLI) with that of ureteroscopic cold knife incision (USCKI) in the treatment of ureteral stricture. Methods Seventy-eight patients with ureteral stricture underwent USHLI (n = 40) or USCKI (n = 38) in the Armed Police Corps Hospital of Jiangsu Province from January 2010 to December 2016. Comparisons were made between the two surgical strategies in the operation time, postoperative complications, hospital days, short-term effect and long-term effect.Results Mild postoperative hematuria occurred in all the patients of the USHLI group, which lasted 1-2 days before it disappeared without intervention, but with no other severe complications as adjacent organ injury, ureteral avulsion, or massive hemorrhage. Moderate postoperative hematuria was observed in all the patients of the USCKI group, which was stopped at 2-3 days by administration of hemostatics. Compared with USCKI, USHLI achieved a significantly shorter operation time ([43.4 ± 5.8] vs [35.3 ± 3.8] min, P < 0.05) and postoperative hospital stay ([5.0 ± 1.4] vs [4.0 ± 0.8] d, P < 0.05), lower incidence of postoperative infection (27.3% vs 7.7%, P < 0.05), and higher cure rate (57.6% vs 87.2%, P < 0.05). Conclusion USHLI, with its advantages of less damage, lower recurrence rate and fewer complications, is obviously superior to USCKI in the treatment of ureteral stricture.
ABSTRACT
OBJECTIVE@#To investigate the effects of Liangxuehuayu Recipe on hemorheology in rats with blood stasis syndrome induced by mutifactor stimuli.@*METHODS@#SD rats were divided into control, model, Liangxuehuayu Recipe (high, middle and low dose, 18, 9, 4.5 g/kg accordingly). Except the control group, blood stasis model was established in the rest groups. The hemorheological parameters were measured and compared.@*RESULTS@#Blood viscosity at high, moderate and low level in rats with blood stasis significantly increased (P<0.05), but blood viscosity at high level and plasma viscosity was significantly decreased in rats induced by some stimuli after Liangxuehuayu Recipe were intra-gastrically administered for 1 weeks (P<0.01, P<0.05).@*CONCLUSIONS@#Liangxuehuayu Recipe is effective in improving hemorheology, and has important application value in the prevention of occurrence and development of ischemic stroke.
