RESUMEN
Objective To evaluate the effectiveness and safety of emergency realignment of urethra with straddle injury under the guidance of ureteroscope. Methods The clinical results of 39 patients with urethra straddle injury having the failure of inputting a urethral catheter from August 2007 to August 2013 in Central People's Hospital of Tengzhou City,Shandong province were retrospectively investigated,and according to the difference in method of operation,the patients were divided into two groups. In group A,there were 27 patients who underwent the first stage perineal urethra repair and anastomosis operation,and in group B,there were 12 patients who underwent urethral realignment operation and insertion of a catheter under the guidance of ureteroscope. The operation time, amount of bleeding in operation,incidence of complications such as urethral stricture,erectile dysfunction,as well as postoperative hospital stay were compared between the two groups. In addition,we searched PubMed/MEDLINE, EMBASE,Wanfang database,China journal full-text database(CNKI),VIP database and China outstanding master's/doctoral dissertation database from which we selected research literatures from 2000 to 2013 on emergency realignment of urethra with straddle injury and conducted Meta-analysis by Revman 5.2 software. Results Compared to group A, the operation time and postoperative hospital stay were significantly shortened in group B〔operation time(minutes):26±15 vs. 71±18,postoperative hospital stay(days):2.6±1.2 vs. 5.2±1.9,both P0.05〕. And patients suffering from urethral stenosis were treated with postoperative transurethral expansion and followed up for 6 to 12 months,including 1 case of urethra expansion invalid to switch to open surgery. Related literatures were researched for Meta-analysis,and 4 literatures were enrolled. Meta-analysis results further confirmed that urethral realignment was more effective than urethral anastomosis for urethral injury〔odds ratio(OR)=2.30,95% confidence interval(95%CI)1.07 - 4.95,P=0.03〕. Conclusion Performing urethral realignment operation under the guidance of ureteroscopy is a better operation in the treatment of urethral straddle injury,having the advantages of shorter operation time,less trauma,quicker recovery and fewer complications.
