患前列腺肥大伴急性尿潴留的病人,急症处理的第一步,均需进行导尿处理。根据我们的临床经验,大多数病例利用常规导尿法是不易成功的,因其导尿管不易通过前列腺部。有时即便用前列腺导尿管(弯头导尿管也称喙状导尿管),也不易成功。其原因是由于前列腺肥大而引起前列腺部尿道弯曲变形,又由于伴有炎症使尿道粘膜水肿,管腔进一步变窄而发生急性尿潴留。在这种情况下,当导尿管到达弯曲变形、粘膜水肿、管腔狭窄的前列腺部时,是不易成功的。加之导尿管刺激发炎的粘膜时,会引起尿道内口 Patients suffering from benign prostatic hyperplasia with acute urinary retention, the first step in emergency treatment, are required for catheterization. According to our clinical experience, the use of conventional catheterization in most cases is not easy because of its poor access to the prostate. Sometimes even with the prostate catheter (beak catheter also called beak catheter), is not easy to succeed. The reason is due to prostatic hypertrophy caused by benign prostatic urethra bending deformation, but also due to inflammation of the urethral mucosal edema, lumen further narrow and acute urinary retention occurs. In this case, when the catheter reaches the bended, mucosal edema, narrow stenosis of the prostate, it is not easy to succeed. Coupled with the catheter to stimulate inflammation of the mucous membrane, can cause urinary tract mouth
