Post-void residual urine issue?
Hello, Doctor.
I had hemorrhoid surgery on August 5, and after catheterization, I developed a urinary tract infection.
I followed up with the urology department and informed the doctor that I usually experience mild frequency of urination.
On August 22, I underwent an abdominal ultrasound and a uroflowmetry test, which showed a post-void residual volume of 60 cc.
The urology department originally scheduled my uroflowmetry for September 1, but they advised me to avoid my menstrual period, so I went in early on August 22.
Since August 18, I have been taking Betmiga PR tablets 25 mg, and I feel some improvement, urinating approximately every 1-2 hours with a volume of around 200 cc each time (since I work from home, I go whenever I feel the urge and do not hold it).
I experience nocturia about once a night, and I feel that my condition is gradually improving.
I have a few questions: 1.
Will the results of the uroflowmetry test I took that day be inaccurate since I was fasting and dehydrated? 2.
Is a post-void residual volume of 60 cc serious? Should I continue to monitor it, or is immediate medication treatment necessary? Is it severe enough to require urodynamic studies? 3.
Given that my urinary infection has just resolved, did I go for the tests too early? I feel that my current urination status is much better than it was on that day.
I apologize for the trouble, but I have anxiety, and these unresolved questions before my follow-up appointment are making it difficult for me to relax.
Thank you for your help.

Hello:
1.
Will the tests I had done that day be inaccurate? - These types of tests require a full bladder; if the urine volume is low, the results can only be considered as a reference.
Generally, multiple tests (2-3 times) are needed for a more accurate assessment.
2.
Is a post-void residual volume of 60cc serious? - It is usually not serious; typically, it requires continued observation.
Whether to initiate medication treatment depends on the individual case.
It may not be severe enough to warrant urodynamic studies, but it depends on whether the symptoms persist despite medication.
3.
I just recovered from a urinary tract infection; did I go for the tests too early? I feel that urinating in my current condition would be much better than that day.
- If the symptoms have improved, that is a good sign.
Wishing you good health.

Post-surgery urinary retention can be a challenging issue, especially following procedures such as hemorrhoid surgery, which may inadvertently affect the urinary tract. Your experience with urinary retention and the subsequent urinary tract infection (UTI) is not uncommon, and it’s understandable that you have concerns about your recovery and ongoing symptoms.
1. Accuracy of the Urinary Flow Test: Regarding your question about the accuracy of the urinary flow test conducted while you were dehydrated, it is indeed possible that the results may not fully reflect your typical urinary function. Dehydration can lead to concentrated urine and may affect the volume you are able to produce during the test. If you felt that your body was lacking hydration at the time of the test, it could have resulted in a lower flow rate and potentially skewed the assessment of your urinary function. Ideally, urinary flow tests are performed when the patient is well-hydrated to ensure more accurate results.
2. Residual Urine Volume: A residual urine volume of 60 cc is generally not considered severe, but it does warrant monitoring. In a healthy individual, the residual volume after urination should ideally be less than 50 cc. However, a volume of 60 cc suggests that there may be some degree of urinary retention. It is essential to continue observing your symptoms and follow your physician's recommendations. If your urinary symptoms improve with medication like Betmiga (mirabegron), which is used to treat overactive bladder, this could indicate that your bladder function is gradually returning to normal.
The decision to initiate further treatment, such as medication or more invasive procedures like urodynamics, typically depends on the persistence of symptoms and the degree of urinary retention. If your symptoms do not improve or worsen, further evaluation may be necessary. Urodynamic studies can provide valuable information about bladder function and help guide treatment options.
3. Timing of the Follow-Up Appointment: As for whether it was too early to conduct the urinary flow test after recovering from a UTI, it is generally advisable to wait until you are fully recovered from any infection before undergoing such assessments. UTIs can cause temporary changes in urinary habits and bladder function, so testing too soon may not provide a clear picture of your baseline urinary health. If you feel that your urinary function has improved since the test, it may be beneficial to discuss this with your urologist during your next visit.
In summary, your concerns about urinary retention and the impact of recent surgery are valid. It is crucial to maintain open communication with your healthcare provider, especially given your anxiety about these issues. They can help clarify the results of your tests, monitor your recovery, and adjust your treatment plan as necessary. If you continue to experience anxiety, consider discussing this with your healthcare provider as well, as they may have resources or strategies to help you manage these feelings during your recovery. Remember, recovery can take time, and it’s essential to be patient with yourself as you heal.
