Frequent urination when standing?
Hello, doctor.
Over the past three months, I have noticed that I experience a strong urge to urinate whenever I stand up, but each time I only pass about 150 cc of urine.
Sometimes, just standing up to make a photocopy sends me rushing to the restroom.
This frequent urination has been quite bothersome, but when I sit down, I don't have this issue; I can go 2 to 3 hours without needing to urinate, with a volume of about 300 to 350 cc.
I initially didn't think much of it, but recently I've started experiencing nocturia, waking up 1 to 2 times at night to urinate.
A few days ago, I visited the hospital for a check-up, and the doctor said my urinalysis was normal, with no signs of bacterial infection.
However, he still suspects inflammation of the prostate or bladder, so he prescribed a two-week course of antibiotics.
I have a follow-up appointment in two weeks.
I would like to ask, besides infection, what other possible causes could explain the frequent urination when standing but not when sitting? Thank you, doctor.

Hello: Since it has been more than three months and if it occurs almost daily rather than just a few times a week, it is recommended to undergo further urodynamic testing.
Currently, please pay attention to exercise, maintain a light diet, avoid beverages and alcohol, and ensure adequate hydration.
Wishing you good health.

Frequent urination when standing can be a perplexing issue, especially when it contrasts with normal urination patterns while sitting. Your symptoms suggest a few potential causes, and understanding these can help guide you toward effective solutions.
Firstly, it’s important to consider the role of the bladder and pelvic floor muscles. When you stand, the position of your body changes, which can affect how your bladder fills and empties. The act of standing may put pressure on the bladder, leading to a sensation of urgency. This can be exacerbated by factors such as anxiety or stress, which can heighten the urgency to urinate.
Another possibility is related to the prostate gland in men. As you mentioned, your doctor suggested that inflammation of the prostate (prostatitis) could be a contributing factor. Prostatitis can lead to urinary symptoms, including urgency and frequency, particularly when standing. The prostate can also affect the bladder's ability to store urine effectively, leading to more frequent trips to the bathroom.
Moreover, the bladder itself may be hyperactive. Overactive bladder syndrome can cause a sudden urge to urinate, often accompanied by increased frequency and nocturia (waking up at night to urinate). This condition can be influenced by various factors, including nerve signals that may be more active when standing.
In addition to these considerations, it’s worth exploring the possibility of bladder irritants in your diet. Caffeine, alcohol, spicy foods, and artificial sweeteners can irritate the bladder and lead to increased urgency and frequency. Keeping a bladder diary to track your fluid intake, diet, and urination patterns can help identify any potential triggers.
Given that your urinalysis came back normal, it’s reassuring that there’s no immediate indication of a urinary tract infection (UTI). However, if the antibiotic treatment does not alleviate your symptoms, further investigation may be warranted. This could include imaging studies or urodynamic testing to assess bladder function and capacity.
In terms of management, here are several strategies you might consider:
1. Pelvic Floor Exercises: Strengthening your pelvic floor muscles through Kegel exercises can help improve bladder control and reduce urgency.
2. Bladder Training: Gradually increasing the time between urination can help train your bladder to hold more urine and reduce urgency.
3. Lifestyle Modifications: Reducing intake of bladder irritants, staying hydrated, and maintaining a healthy weight can positively impact urinary symptoms.
4. Medication: If your symptoms persist, medications that relax the bladder or reduce urgency may be prescribed by your healthcare provider.
5. Follow-Up: Since your symptoms have persisted despite initial treatment, it’s essential to follow up with your healthcare provider. They may recommend further evaluation or refer you to a urologist for specialized care.
In summary, while frequent urination when standing can be frustrating, understanding the underlying mechanisms can help you find effective solutions. It’s essential to maintain open communication with your healthcare provider to explore all potential causes and treatments. If your symptoms continue or worsen, don’t hesitate to seek further evaluation to ensure you receive the appropriate care.
