Urethral intubation is a little painful, but can be effectively tolerated for all patients. If pain during intubation is a concern, lidocaine latex can be injected into the urethra and can provide significant pain relief. For many surgical patients, intubation is necessary to allow for the inability to urinate because of the anesthesia condition, and intubation can be effective in draining urine. For urethral surgery, the tube should be inserted for continuous support for more than two weeks, this is for the treatment of the disease and this intubation must be accepted psychologically. For the presence of acute urinary retention, there is no other way to drain urine, and only intubation is possible. After intubation, it is recommended to drink more water and urinate more often to effectively prevent infection.
