The reason for the white liquid at the end of the urine is possible: 1. If you are a young man, you may be suffering from prostatitis, and you can exclude the white sticky liquid at the end of urination, mostly prostate fluid. The patient is accompanied by symptoms such as frequent urination, urinary urgency, or pain in the perineal area after sitting for a long time. 2. purulent infection of the urethra or bladder, which can discharge pus, manifesting as white pus, accompanied by symptoms such as stinging in the urethra, frequent urination, urinary urgency, etc. It is necessary to carry out laboratory tests and culture tests of the urine to further confirm the diagnosis. 3. urethral diverticulum. Pus, infection and pus accumulation in the diverticulum of the urethra can occur. With the completion of urination, the mucous membrane of the urethra contracts and closes in the process of squeezing the pus from the diverticulum, which is discharged from the urethra. It is often accompanied by frequent and urgent urination, or white mucus is often secreted from the urethra. Urethroscopy or MRI of the urethra is required to further rule out the presence of diverticula.
