"Pearl-like droplets after urination"


Hello, urology experts.
Many male individuals (ages 18-30) have inquired about a situation where, after urinating, they believe they have finished and put their penis back into their pants, only to find that one or two drops of urine leak out after walking a few steps, leading to stained or yellowed underwear.
Most responses typically include the following points:
1.
Wearing tight pants can cause slight pressure on the groin and urethra, and it is advised to lower the pants below the knees while urinating.
2.
Cold weather can lead to poor circulation.
3.
Autonomic nervous system contraction.
4.
Shy bladder syndrome.
5.
Overly tense bladder opening and pelvic floor muscles, which do not relax enough, causing some urine to be trapped in the urethra.
Once the pants are on and the body relaxes, it may leak out.
6.
The male urethra is longer.
7.
For young men, a few drops may come out after urination, often due to detrusor-sphincter dyssynergia; if severe, medication may be required.
I have meticulously observed myself over several years, and the situation has remained the same since I was 20, now at 30 years old (though I may have added one more drop over the decade).
I have undergone urodynamics, urinalysis, white blood cell count, and stone tests, all of which are normal.
My pants are loose, and I am relaxed in a stress-free environment.

I would like to ask, "Is it normal for healthy young males to experience this under typical circumstances?" I am puzzled, troubled, and concerned...
I hope to receive the professional opinions of urology doctors and experts.

~Thank you very much~

In response to your question, I also have some concerns, but please don't worry too much; this is a functional issue, as long as urination is possible.

Post-urination dribbles, or the phenomenon where a few drops of urine are released after a man believes he has finished urinating, is a common issue that many young men experience. This can be particularly frustrating and embarrassing, leading to concerns about hygiene and personal health. Understanding the underlying causes can help alleviate anxiety and provide clarity on whether this is a normal occurrence.

Firstly, it is essential to recognize that the male urinary system is complex. The urethra, which carries urine from the bladder out of the body, is surrounded by various muscles, including the sphincter muscles that control the flow of urine. After urination, if these muscles do not fully contract or if there is residual urine in the urethra, it can lead to dribbling. This is often exacerbated by several factors:
1. Anatomical Factors: The male urethra is longer than that of females, which can contribute to the retention of urine in the urethra after voiding. The anatomy of the pelvic floor and the positioning of the bladder can also play a role in how effectively urine is expelled.

2. Muscle Coordination: The coordination between the bladder and the sphincter muscles is crucial. If there is a lack of coordination, it may result in residual urine being expelled after the initial voiding. This is particularly common in younger men, as the pelvic floor muscles may not be fully developed or may require more training to function optimally.

3. Tight Clothing: Wearing tight clothing can compress the pelvic area, potentially affecting the flow of urine and the ability of the sphincter muscles to close properly. It is advisable to wear looser-fitting clothing to reduce any unnecessary pressure on the urethra.

4. Cold Weather: Cold temperatures can cause the muscles to contract, which may lead to a temporary reduction in blood flow and could affect the ability to fully empty the bladder. This is often why men may experience more dribbling in colder weather.

5. Nervous System Response: The autonomic nervous system plays a role in bladder control. Stress or anxiety can lead to muscle tension, which may prevent the bladder from fully emptying. This is sometimes referred to as "shy bladder syndrome," where anxiety about urination can lead to incomplete voiding.

6. Pelvic Floor Muscle Tension: If the pelvic floor muscles are overly tense, they may not relax adequately during urination, leading to residual urine being trapped in the urethra. This can result in dribbling once the individual stands up and relaxes.

7. Age and Hormonal Changes: While this issue is common in younger men, hormonal changes and the natural aging process can also affect urinary function. As men age, changes in hormone levels and muscle tone can impact bladder control.

In conclusion, while post-urination dribbles can be a nuisance, they are generally considered a normal occurrence for many young men. If the dribbling is persistent, severe, or accompanied by other symptoms such as pain, burning, or changes in urinary frequency, it is advisable to consult a healthcare professional. They can conduct a thorough evaluation to rule out any underlying conditions, such as urinary tract infections or prostate issues.

For those experiencing mild dribbling, practicing pelvic floor exercises (Kegel exercises) can help strengthen the muscles involved in urination and improve control. Additionally, ensuring a relaxed environment during urination and adopting proper techniques, such as waiting a moment before standing up, can help minimize the occurrence of dribbles. Remember, maintaining open communication with healthcare providers about any concerns is crucial for managing urinary health effectively.

Dr. Chen Zhirong reply Urology
It is recommended that you visit a urology clinic for a prostate ultrasound and post-void residual urine testing to assess whether the angle of the prostatic urethra is normal and if the urethral sphincter is contracting properly. This phenomenon should not occur in normal males.
