TURP后尿道狭窄的发生率约在10%左右、以前认为硅橡胶导尿管是引起尿道狭窄的主要原因,但这种导管很少引起膀胱颈狭窄。与耻骨上膀胱置管弓流相比,经尿道硅橡胶导尿管有较高的尿道狭窄发生率,因而手术效果较差。Hammasten比较了两种材料导管经尿道引流和耻骨上引流尿道狭窄的发生率及手术效果。病人和方法:298例病人TURP术后随机分为3组,94例病人用聚氯乙烯导管作耻骨上膀胱引流,另
The incidence of posterior urethral stricture (TURP) is about 10%. Silicone rubber catheters were previously considered as the main cause of urethral stricture. However, such catheters rarely cause bladder neck stenosis. Compared with suprapubic catheterization, transurethral silicone rubber catheterization has a high incidence of urethral stricture, and thus the surgical effect is poor. Hammasten compared the incidence of transcatheter urethral drainage and suprapubic drainage of urethral strictures in two types of materials and the surgical effect. Patients and Methods: 298 patients were randomly divided into three groups after TURP surgery, 94 patients with polyvinyl chloride catheter for suprapubic bladder drainage, and the other
