Comparison of the clinical effect of transurethral plasma electrotomy with rod electrode and end-to-end urethral anastomosis in the treatment of short urethral stricture
Objective To investigate the clinical efficacy of transurethral plasma electrotomy with rod electrode and end-to-end urethral anastomosis in the treatment of short urethral stricture.Methods 125 male patients with short urethral stricture(＜2 cm)who were admitted to our hospital from January 2014 to December 2020 were retrospectively analyzed.According to different surgical methods,they were divided into transurethral plasma resection with rod electrode(minimally invasive group)and urethral end-to-end anastomosis(open group).According to the length of urethral stricture,the minimally invasive group was divided into minimally invasive group 1(stricture length≤1 cm),minimally invasive group 2(stricture length1-2 cm),open group 1(stricture length ≤1 cm)and open group 2(stricture length 1-2 cm).The four groups were compared with each other,and the surgical success rates were compared between the four groups.Results The success rate of the minimally invasive group 1 and the open group 1 was 88.57％and 93.10％,respectively.There was no significant difference between the two groups(P＞0.05).The surgical success rate of the minimally invasive group 2 and the open group 2 was 67.86％and 90.91％,respectively.The surgical success rate of the minimally invasive group 2 was significantly lower than that of the open group 2.The difference was statistically significant(P＜0.05).The surgical success rate of minimally invasive group 1 and minimally invasive group 2 was 88.57％and 67.86％,respectively,the difference was statistically significant(P＜0.05).The success rate of operation in the open group 1 and the open group 2 was 93.10％and 90.91％,respectively,and there was no significant difference between the two groups(P＞0.05).Conclusion Transurethral plasma resection with rod electrode is preferred for urethral stricture with length≤1 cm,because the success rate of this surgery is the same as that of open surgery,and the surgical trauma is small and the recovery is fast.For 1-2 cm urethral stricture,minimally invasive surgery has less trauma and faster recovery,but open surgery has a higher success rate.The choice of surgical method needs to weigh the advantages and disadvantages and take comprehensive consideration.
