Contrast Study On The Efficacy Of Ventral Capping And Lateral Anastomosis Tongue Mucosa Transplantation For Male Anterior Urethral Stricture

Purpose:To explore the surgical safety and postoperative efficacy of ventral capping and lateral anastomosis tongue and urethroplasty for the treatment of male anterior urethral stricture,and provide reference for clinical operation.Methods:Retrospective analysis of 66 cases of male urethral stricture in the China–Japan Union Hospital of JILIN University from January 2015 to December 2017.The reasons for the previous urethral stricture and dysuria were the main symptoms.Non-surgical treatment such as urethral dilatation was ineffective.The patients were divided into 38 cases of lateral anastomosis group and 28 cases of ventral side capping group.The two groups of patients were treated with tongue mucosa transplantation urethroplasty.The age,onset time,urethral stricture length and preoperative maximum urine were compared and compared between the two groups.Flow rate,surgical success rate,operation time,intraoperative blood loss,indwelling catheter time,hospitalization time,maximum urinary flow rate after 6 months and surgical complications.The difference of maximum urinary flow rate between two groups after tongue mucosa transplantation and before and after operation was compared and analyzed.Results:In this study,66 patients completed the operation successfully.1.There was no significant difference in age,onset time,urethral stenosis length and preoperative maximum urinary flow rate between the two groups(P>0.05).2.There were significant differences in the operation time and intraoperativeblood loss between the two groups(P<0.05),the indwelling catheter and hospitalization time,the difference was not statistically significant(P>0.05).3.The maximum urinary flow rate was compared between the two groups after 6months of follow-up.The difference was statistically significant(P<0.05).The ventral capping group was superior to the lateral anastomosis group.The mean maximum urinary flow rate difference was statistically significant(P<0.01).4.The incidence of complications during hospitalization compared with gross hematuria was higher in the ventral capping group than in the lateral anastomosis group(P<0.05).Urinary tract infection and wound infection,long-term complications of surgery The difference was not statistically significant(P>0.05).Conclusion:1.After 6 months of follow-up,the maximum urinary flow rate in the ventral capping group was better than that in the lateral anastomosis group,suggesting that in the treatment of anterior urethral stricture with iatrogenic injury,ventral lingual mucosa transplantation has advantages.2.Tongue mucosa transplantation urethroplasty can significantly improve the symptoms of dysuria in patients with urethral stricture.It is an ideal surgical procedure for the treatment of male patients with anterior urethral stricture.It is worthy of promotion and application by clinicians.
