Hi doctor,

I got my urine test done. What is the possibility of a UTI? I am attaching my reports. What does it imply? I have a congenital diaphragmatic hernia in my left. Kindly give your opinion.



Welcome to

The urinalysis shows the following findings (attachments removed to protect the patient's identity): The slight increase in specific gravity means you are slightly dehydrated. So it would help if you increase your fluid intake more, the presence of protein, ketone, and bilirubins may be explained by the dehydration state, the results do not point to a UTI (urinary tract infection) since nitrite (which tests for the presence of bacteria within the urinary system) is negative and normal pus cells (these are the white blood cells in our body that fight infection, yours is within normal limit). However, the presence of an increased amount of mucus threads (2+ mucus thread means there is discharge) and the presence of moderate bacteria point to the possibility of a sexually transmitted disease (STD). Have you noticed any penile discharge? Any palpable enlarged lymph nodes on your inner thighs? Have you experienced this before? Any history of sexually transmitted diseases in the past? Are you aware of your partner's sexual history and possible diseases in the past? Normally, it would be best to do a urine culture to determine what kind of bacteria, but we can ascertain a proper diagnosis with proper history and physical examination. I would highly suggest you consult with a local physician in your area to be properly diagnosed and get treated accordingly. I suggest you get a urine culture done. Practice safe sex. I hope this was helpful. Thank you.

Hello doctor,

Thank you.

What kind of STD do you think is this? There is no discharge. Kindly give your opinion.



Welcome back to

It is possible you may not have noticed it yet. It could be clear and minimal discharge. But again, to diagnose you correctly, you need to see a doctor within your area. Different STDs could cause it, but the most common, taking into consideration your urinalysis findings, would be chlamydia and gonorrhea infections. Both are treatable and curable. Management would only require you to take two single-dose tablets. But I need to emphasize. It is best to see a doctor to be adequately evaluated and to ascertain the diagnosis. For now, a diagnosis of UTI is highly unlikely because of those above I stated, but the possibility of an STD is likely. Other differentials would be kidney stones or cancer but highly unlikely too because of the negligible presence of RBCs (these are red blood cells) and no findings of other dysmorphic or crystals, etc., structures on microscopic examination. I hope this was helpful. Thank you.

Hi doctor,

Thank you.

I am attaching is the urinalysis and urine culture report. What does it mean? Kindly give your opinion.



Welcome back to

The urine culture shows the negative growth of bacteria. The scanty result means it could be a normal bacteria that grows on our skin or contamination, as mentioned. Since you deny any presence of penile discharge and the culture shows the unremarkable result. I would like to suggest doing a repeat urinalysis test after one week. Make sure you drink plenty of fluids and well hydrated at all times. The urinalysis result of the presence of bacteria and mucus threads could also be contaminants. But to be sure, please do a repeat urinalysis after one week. However, if you do notice a sudden onset of penile discharge or any other symptoms such as fever, palpable masses on your groin and inner thighs. Please do a culture of the discharge if there is any discharge. I hope this was helpful. Thank you.
