Background

Indwelling catheterization is widely applied in clinic, and is one of the most basic diagnosis and treatment technologies, and is mainly applied to patients who have difficulty in micturition, need to monitor urine volume and urethral stricture, such as urinary retention, bladder cancer, urinary incontinence, after surgical operation, bladder irrigation, severe burns and the like. Indwelling catheters, while solving the above problems, also present certain risks in handling. The difficulty of indwelling the urinary catheter for the patients with traumatic urethral injury, postoperative urethral stricture, senile prostatic hypertrophy and hyperplasia and the like is high, and the failure rate is high.

For the patients who fail to keep the urinary catheter in the conventional way, the traditional treatment method is to use a thinner urethral probe to induce and check, determine the position and the degree of urethral stricture, use a thicker probe to expand the stricture step by step, and finally keep the urinary catheter to drain urine and support the stricture. Patients with severe urethral stricture need to repeat urethral dilation until a catheter of a satisfactory diameter can be indwelling.

The bougie of present clinical application is mostly metal material, passes in and out the urethra bougie repeatedly and keeps somewhere the catheterization, not only increases patient's misery, consumes medical resources, has the damage of normal urethra mucous membrane simultaneously, has complications such as urethral hemorrhage, tear, fracture even, causes great misery for patient.
