Multi-center clinical research of different surgical treatment of male traumatic urethral stricture

Objective To discuss the influencing facts of the outcome of different surgical treatment of male traumatic urethral stricture.Methods The maiden therapy effects of 237 cases of traumatic urethral stricture of multi-center were reviewed and tested by Log-rank and Chi-square test and partitions of χ2.Results The length of the stricture was divided into two groups.In grpup 1,the length was 0-2 cm,but in group2 the length was 2-4 cm.The recurrence rate in group 2 was significantly higher than that in group1(P0.05).The recurrence rate in patients with perioperative urinary infection was significantly higher than that in patients without perioperative urinary infection(P0.05).In maiden therapy methods of stricture,The recurrence rate in patients with urethral dilatation was significantly higher than that in patients with anastomotic urethroplasty(P0.01),but no significance between urethral dilatation and internal urethrotomy(P0.05).And the recurrence rate in patients with internal urethrotomy was significantly higher than that in patients with anastomotic urethroplasty(P0.01).Conclusions The length of the stricture,perioperative urinary infection and maiden therapy methods of stricture are all important factors of the recurrence of urethral stricture;The incidence of urethral stricture recurrence is relation to the length of the stricture after urethrotomy.If the length of the stricture shorter than 2cm the incidence of urethral stricture recurrence is low,in contrast,if the length longer than 2cm the incidence is high;After anastomotic urethroplasty the incidence of urethral stricture recurrence is relation to perioperative urinary infection and operation,but is not relation to length of the stricture,site of stricture and previous stricture treatment.Compared with other surgical treatment,the incidence of urethral stricture recurrence of anastomotic urethroplasty is the lowest.
