Abstract:
ObjectiveTo improve the treatment of urethral stricture and evaluate the applicative effects of wire-guided supporting catheterization in clinical urology. MethodsDuring January 2004 and December 2005, the patients with urethral stricture were dwelled with the catheters using the traditional guideless catheterization (group A). If the dwelling failed,it will be replaced by the wire-guided supporting catheterization using the improved catheters. During January 2006 and December 2009, the patients with urethral stricture were dwelled with the improved catheters using wire-guided supporting catheterization ( group B) straightly. Compared the first-time dwelling success incidence,the incidence of catheter associated urinary tract infection and side-effect events. Then after 1 year, compared the urethral stricture recrudescence and the course of treatment. ResultsThe success incidence of first-time catheterization in group A was 48.98％ (24/49) ,and in group B was 97.94％ (95/97) ,there was significant difference between 2 groups;The incidence of catheter associated urinary tract infection in group A was 12.24％, and 8. 25％ in group B, there was significant difference between 2 groups; As for the course of treatment, group A was 46. 2w,group B was 32.7w;The urethral stricture recrudescence in group A and B were 16.33％ and 9.28％ respectively,and there was significant difference between 2 groups. ConclusionThe wire-guided supporting catheterization, which minimize the injury and simplify the operation of internal urethrotomy,could makes the improved catheter easy to induct and replace, improve the success rate of first time-catheterization and prevent the false tunnel damage and new scar expansion. It could make benefit to reduce of incidence of catheter associated urinary tract infection and urethral stricture recrudescence,but also could shorten the course of treatment significantly.
