Preventive effect of Ningmitai combined with tamsulosin in double-J stent syndrome / 中国中西医结合急救杂志

ABSTRACT

Objective To investigate the clinical outcomes derived from Ningmitai combined with tamsulosin to prevent double-J stent syndrome after laser lithotripsy with ureteroscope. Methods 117 patients underwent laser lithotripsy with ureteroscope and then placed a double-J stent for draining were collected from January 2010 to January 2013. Patients with double-J stent placement were divided into four groups determined by dosage regimen. Tamsulosin group (30 cases) was treated with tamsulosin (0.4 mg once daily) lonely, Ningmitai group (29 cases) was treated with Ningmitai (1.52 g, trice time a day) lonely, tamsulosin combined Ningmitai group (30 cases) was treated with tamsulosin and Ningmitai at the same time, operation control group (28 cases) was neither tamsulosin nor Ningmitai. The catheter was removed on the 3rd day post-lithotripsy and then remained double-J stent for 1 month. The scores of urinary tract, pain and the incidence of gross hematuria were assessed. Results The significant differences in the improvement of symptom score (χ2=22.038, P=0.000), pain score (χ2=9.876, P=0.020) and hematuria (χ2=8.000, P=0.046) were found among tamsulosin group, Ningmitai group, and tamsulosin combined Ningmitai group. The number of patients with symptomless, slight symptom in tamsulosin combined Ningmitai group were higher than those of tamsulosin group, Ningmitai group, operation control group (symptomeless14 vs. 6, 3 and 2 cases;slight symptom13 vs. 9, 5, 4 cases). The number of patients with>Ⅱpain score (7 vs. 9, 14, 17 cases) and incidence of hematuriag [26.6%(8/30) vs. 56.7%(17/30), 58.6% (17/29), 53.6% (15/28)] were lower in tamsulosin combined Ningmitai group than those of tamsulosin group, Ningmitai group, operation control group. The drug combination of Ningmitai with tamsulosin had the synergism to relived symptom and pain, and showed the more obviousthan lonely use. Conclusion The drug combination of Ningmitai with tamsulosin can be used in clinic for prophylactic purpose to prevent double-J syndrome.
