What is the pain after changing the catheter?

In the process of replacing the catheter or after replacing the catheter, it is possible to cause pain in the lower abdomen or urethra. The reasons mainly include the following aspects: First, when replacing the catheter, the catheter needs to enter the bladder along the urethra from the external orifice of the urethra. In this process, it will cause discomfort in the urethra. However, under normal circumstances, after replacing the catheter, the pain will gradually disappear and last for a short time. Second, there is bladder spasm after changing the catheter, causing severe pain in the lower abdomen and urethra, requiring spasmodic pain relief and symptomatic treatment. Third, when changing the catheter, it may cause urethral damage and urethral pain.
