Surgical treatment of post-traumatic complex posterior urethral stricture in male patients / 中华创伤杂志

ABSTRACT

Objective To investigate the therapeutic effect of post-traumatic complex posterior urethral stricture in the male patients.Methods Clinical data of 479 male patients with post-traumatic complex posterior urethral stricture were reviewed.One-stage resection of the stenosis and end-to-end anastomosis was performed in 422 patients and scrotal flap with blood pedicle posterior urethroplasty in 57.Results The mean operation time was 115 minutes(range,90-140 minutes).The mean blood loss was 225 ml(range,100-300 ml).No intraoperative blood transfusion was needed.The mean follow-up time was 15 months(range,12-24 months).Among the 422 patients performed end-to-end anastomosis,386 patients had good voiding and 36 had dysuria because of the formation of anastomotic stoma valve(21 patients)or stricture ring(15 patients).The problem was resolved by transurethral valve/stricture ring resection.Among 57 patients undergone posterior urethroplasty,45 patients had good voiding nine patients were found with anterior urethra-skin tube anastomotic stoma stricture,of which four patients were treated by urethral dilatation and five by endourethrotomy; three patients were found with posterior urethra-skin tube anastomotic stoma stricture,of which one patient was treated by urethral dilation and two by endourethrotomy.Conclusions One-stage resection of the stenosis and end-to-end anastomosis is the main treatment for post-traumatic complex posterior urethral stricture.If the condition of the patients does not allow the end-to-end anastomosis,posterior urethroplasty can be an alternative.
