Objective:To compare the effect of balloon dilation under ureteroscope and cold knife incision in the treatment of male posterior urethral stricture.Methods:The clinical data of 115 patients with posterior urethral stricture admitted to the People's Hospital of Jincheng from 2012 to 2018 were retrospectively analyzed.They were divided into two groups depending on the surgical procedure.In the balloon group, 59 cases were treated with ureteroscopic balloon dilatation.In the cold knife group, 56 cases were treated with internal urethral cold knife incision.The operation time, postoperative hospitalization days, postoperative maximum urine flow rate, recurrence rate and reoperation rate were compared between the two groups.Results:There was no statistically significant difference in operation time and postoperative hospitalization day between the two groups(all P>0.05). The maximum urine flow rate at 3 months after surgery was (19.41±5.49)mL/s in the balloon group, which was significantly higher than that in the cold-knife group[(17.07±6.17)mL/s]( t=2.147, P<0.05). The recurrence rate and reoperation rate of the balloon group were 13.56%(8/59) and 8.47%(5/59), respectively, which were significantly lower than 32.14%(18/56) and 23.21%(13/56) of the cold knife group(χ 2=5.671, 4.728, all P<0.05). No significant surgical complications were observed in the two groups. Conclusion:Balloon dilation under ureteroscopy in the treatment of male posterior urethral stricture has obvious advantages compared with cold knife incision, and it is a better surgical method for the treatment of male posterior urethral stricture.
Résumé
Objective To compare minimally invasive percutaneous nephroscope and channel percutaneous nephroscope clinical curative effect for the treatment of kidney stones.Methods According to the digital table, 1 10 cases of patients with renal stones were selected and randomly divided into the control group 58 cases and obser-vation group of 52 cases.The control group underwent big channel percutaneous nephrolithotomy(PCNL),the observa-tion group were treated by minimally invasive percutaneous nephrolithotomy(MPCNL).Compared the two groups of patients with stone size,operation time,bleeding volume,decreased hemoglobin values before and after operation,and one-staged stone clearance rate.The changes of renal function in the two groups of patients before and after operation were analyed.Results The two groups with operation were completed successfully,no bleeding and other operation condition happened.The operation hemorrhage of the control group was (118.7 ±31.3)mL,the operation hemorrhage of observation group was (56.8 ±31.7)mL,there was a significant difference between the two groups (t=-10.192, P0.05).Renal function of the two groups were not significantly changed before and after 4 weeks of opera-tion,the two groups showed no significant differences(P>0.05 ).Conclusion The curative effects of two kinds of operations are similar,but the amount of hemorrhage of minimally invasive nephrolithotomy is less.Two kinds of opera-tion methods had no significant effects on patients renal function.
