What is the sequela of catheter insertion?

During the indwelling catheter, the following complications may occur, most commonly urinary tract infection. If the catheter is inserted without strict aseptic procedures, pathogenic microorganisms such as bacteria around the urethral orifice may be introduced into the urethra through the catheter, resulting in inflammation of the urethra, prostate, testicles and epididymis. The second common complication is easy to cause urethral damage, especially in elderly men, elderly men often accompanied by prostatic hyperplasia, resulting in urethral stricture, in the process of catheter insertion, if too violent, will cause urethral damage, resulting in hematuria performance. The third common complication is bladder dysfunction, which is more common in patients with prolonged catheter retention. Failure to clamp the catheter in time will cause bladder contracture, and bladder urination disorder will occur after catheter removal.
