What happened to thick urine after catheter insertion?

After the catheter is inserted, some patients may feel that the urine line is slightly thicker than usual after removing the catheter. This is because after the catheter is left in the body for a period of time, it can play a role in slightly dilating the urethra. The urethra becomes wider than usual, and the urine line feels smoother than usual. These conditions may be short or may last for a while. When the urethral dilation continues, the urine will gradually return to the level before the catheter is inserted. For example, after a period of indwelling catheterization in patients with benign prostatic hyperplasia, urination is smoother due to the role of urethral dilation. However, with the weakening of dilation, benign prostatic hyperplasia further develops, urination can be restored to the previous level, and prostate surgery must be performed to completely improve the symptoms of urinary obstruction. Therefore, for some patients after indwelling urinary catheter after urination becomes thick, because the catheter has a certain role in expanding the urethra, will make urination more unobstructed, urine line thicker.
