Abstract:

Objective　To evaluate the therapeutic effect of Indwelling catheters with build-in zebra urological guidewires for patients with difficult urethral catheterization. Methods　Sixty-nine patients with difficult urethral catheterization who were 51-81 years old and treated at Inpatient Department, Clinic, and Emergency Room at Yuebei People's Hospital from 2017 to September 2021 were collected, including 67 males and 2 females. The causes of difficult urethral catheterization included benign prostatic hyperplasia (50 cases), anterior urethra stricture (7 cases), posterior urethra stricture (3 cases), posterior urethra calculus (2 cases), female urethral orifice stricture (2 cases), urethral external orifice stricture resulted from phimosis (2 cases), urethral injury (2 cases), and difficult urethral catheterization resulted from carcinoma of penis (1 case). All the patients were indwelled catheters with build-in zebra urological guidewires. Results　All but 2 cases successfully finished urethral catheterization via catheters with build-in zebra urological guidewire in lumens; the 2 failure cases with benign prostatic hyperplasia underwent percutaneous suprapubic cystostomy instead. The total success rate was 97.1% (67/69). Conclusions　Catheter with build-in zebra urological guidewire in lumen Indwelling catheters with build-in zebra urological guidewires for patients with difficult urethral catheterization can significantly increase the success rate. It is a simple, safe, effective, and economical method.
