Whether or not you need to wipe with paper after peeing needs to be determined on a case-by-case basis. Men generally do not need to wipe. If a man has urethral obstruction, such as prostate hyperplasia or posterior urethral valve, after urination due to the slow closure of the urethra, the closing pressure is not stable and so on, will lead to urine residue in the urethra can not be discharged in time, you can use the paper in the urethral opening to wipe locally, so that the glans area to keep dry, to prevent bacterial infections from occurring. If the woman after urination, due to the influence of physiological structure, urine will flow to the lower part. At this time you can use paper to wipe, but should pay attention to the direction of wiping, because women’s urethral opening and vaginal opening and anus distance is relatively close, easy to lead to the anus at the bacteria brought to the urethral opening, which led to urinary tract inflammation and other situations occur. If wiping is performed, it should be done in the direction of the urethra toward the anus. Therefore, if a woman has urine residue after urination, it is possible to wipe, but pay attention to the direction of wiping.
