Possible Causes of Frequent Urination


Hello Dr.
Du,
In the past three months, I have been experiencing frequent urination, which led me to visit the hospital.
I underwent ultrasound examinations of my kidneys and bladder.
The kidneys showed no issues and no stones were found, while the post-void residual urine was less than 20cc.
The outpatient physician mentioned that this is normal.
A urinalysis did not indicate any infection or inflammation.
However, I have been experiencing a dull pain below my navel, which worsens with pressure.
The doctor suspects interstitial cystitis and has scheduled a cystoscopy in two weeks.
Additionally, since last month, I have noticed that the flow rate of the final part of my urine stream is very slow, sometimes to the point of dripping.
I often feel like I haven't completely emptied my bladder, but even after standing for a long time, no more urine comes out.
There have been a few instances in the past two weeks where, after using the restroom and putting on my pants, I unconsciously urinated a small amount again after walking a few steps.
However, the outpatient doctor said that at my age, it is unlikely to be a prostate issue and suggested that it is just a matter of not fully emptying my bladder, which he considers normal.
But shouldn't this be classified as interrupted urination? It seems to me that this is no longer a normal phenomenon.
Regarding interstitial cystitis, I found online that it typically causes pain when the bladder is full, but my lower abdominal pain does not seem to worsen or improve with bladder fullness or urination.
Sometimes, even just tightening my abdomen causes discomfort and a sense of urgency, which seems different from what I read online.
I have also considered whether the pain might be related to my intestines, but I only found information about diverticulitis and irritable bowel syndrome potentially causing frequent urination.
However, I have not experienced fever, chills, constipation, or diarrhea (I currently have a regular bowel movement once a day, and my stools are neither overly hard nor watery), so it does not seem to fit the profile of diverticulitis or irritable bowel syndrome.

Could you please advise if there are other potential causes that could simultaneously lead to lower abdominal pain and frequent urination? Thank you, doctor.

Hello: In men, general urinary difficulties can be categorized into three types: prostate issues, bladder dysfunction, and problems with the urethral sphincter.
Of course, some individuals may have a combination of two issues.
Typically, if symptoms are present, after an initial assessment, medication may be prescribed.
If there is no improvement, further examinations such as cystoscopy and urodynamics are necessary to diagnose or rule out certain conditions.
Wishing you good health.

More Info


Frequent urination can be a distressing symptom that significantly impacts daily life. Based on your description, it seems you have undergone various evaluations, including kidney and bladder ultrasounds, which have ruled out significant issues such as stones or infections. However, the presence of persistent lower abdominal pain and changes in urination patterns warrants further investigation.

One potential cause of your symptoms could be interstitial cystitis (IC), also known as painful bladder syndrome. This condition is characterized by chronic pelvic pain, pressure, or discomfort in the bladder area, often accompanied by frequent urination. While you mentioned that your pain does not seem to correlate with bladder fullness or emptying, it is still possible that IC could be a factor, as its symptoms can vary widely among individuals. The upcoming cystoscopy will help provide more clarity on this diagnosis.

Another possibility is bladder overactivity, which can lead to urgency and frequency of urination. This condition can occur independently of infections or structural abnormalities. The slow urine flow and the sensation of incomplete emptying you described could also be indicative of bladder dysfunction. In some cases, this can be associated with pelvic floor dysfunction, where the muscles that control urination do not function optimally.

Your concern about the abdominal pain could also suggest a gastrointestinal issue. Although you have not experienced symptoms typical of diverticulitis or irritable bowel syndrome (IBS), conditions such as pelvic floor dysfunction or chronic pelvic pain syndrome could manifest as both urinary and abdominal symptoms. The pelvic floor muscles can influence both bladder and bowel function, and tension or dysfunction in these muscles can lead to discomfort and altered urinary patterns.

Additionally, neurological conditions affecting bladder function should not be overlooked, especially if there is a history of any trauma or surgery in the pelvic region. Nerve damage or irritation can lead to symptoms such as urgency, frequency, and incomplete bladder emptying.

Given the complexity of your symptoms, it is crucial to continue working closely with your healthcare provider. Here are some recommendations for managing your situation:
1. Follow-Up Appointments: Ensure you attend your scheduled cystoscopy and any follow-up appointments. This will help rule out or confirm interstitial cystitis or other bladder conditions.

2. Symptom Diary: Keep a detailed diary of your symptoms, including the frequency of urination, any associated pain, and dietary habits. This information can be invaluable for your healthcare provider in determining the underlying cause.

3. Pelvic Floor Therapy: If pelvic floor dysfunction is suspected, consider consulting a physical therapist specializing in pelvic health. They can provide exercises and techniques to help alleviate tension and improve bladder function.

4. Pain Management: Discuss pain management strategies with your doctor. This may include medications, lifestyle changes, or alternative therapies.

5. Dietary Considerations: Some individuals find that certain foods or beverages can exacerbate bladder symptoms. Keeping a food diary may help identify any potential triggers.

6. Mental Health Support: Chronic pain and urinary issues can lead to anxiety and stress. If you find that your symptoms are affecting your mental well-being, consider seeking support from a mental health professional.

In conclusion, while your symptoms are complex and multifactorial, continued evaluation and a multidisciplinary approach will be key in addressing both the urinary and abdominal concerns. Your proactive approach in seeking answers is commendable, and with further investigation, you can work towards finding relief and improving your quality of life.
