Regarding urinary issues?


Hello Dr.
Hsu: I have several questions regarding urological issues and hope you can help me answer them!
1.
I drink 3000cc to 5000cc of water daily.
I read online that this could be harmful to the kidneys.
Is that true? What is the normal amount of water intake?
2.
I have been engaging in excessive masturbation (almost daily for over four years).
Does this lead to benign prostatic hyperplasia or prostatitis? What diseases or negative effects can result from excessive masturbation? If so, will abstaining for a period of time, followed by appropriate sexual activity and a normal routine, help restore health? Or should I definitely see a doctor?
3.
Recently, during an examination of my groin area, I found two lymph nodes on the left side (approximately 1.1-1.2 cm and 0.5-0.7 cm) and one on the right side (about 0.7-0.9 cm).
Is it normal to palpate lymph nodes in the groin?
4.
I previously experienced frequent urethritis.
Does this increase the risk of developing urinary system cancers?
5.
Sometimes after urination, my urine has a plastic-like smell.
Is this normal? Additionally, my urine used to be yellow, but recently it has been slightly yellow-green (more accurately, clear but close to green).
Is this normal?
6.
I am 29 years old, do not smoke, have rarely consumed alcohol in my life, and exercise regularly.
At my age, should I start worrying about urinary system cancers (bladder cancer, kidney cancer, prostate cancer, testicular cancer)?
7.
Does bladder cancer always present with hematuria? What are the symptoms of bladder cancer?
8.
Should I see a doctor if my urine splits while urinating? Sometimes after urination, there are still a few drops left; does this mean my bladder is not emptying completely?

Hope you are happy every day:
1.
Maintain a daily urine output of 1200-1500 milliliters.

2.
There are no reports from Western medicine regarding this matter.

3.
It is best to undergo an examination, as certainty cannot be established otherwise.

4.
Frequent infections may lead to a higher likelihood of cellular mutations.

5.
It is not possible to determine if urine is normal based solely on appearance or color.

6.
Cancer typically occurs in older age, particularly in individuals over 65 years old.

7.
Many cases of bladder cancer present with hematuria (blood in urine).

8.
Urinary splitting is often due to lower urine volume or issues such as urethral adhesion.

If there are any unclear points, feel free to ask again for further discussion and research.

Hello! Thank you for your questions regarding various urological concerns. It’s great that you’re taking an active interest in your health. Let’s address each of your queries one by one.

1. Daily Water Intake: Drinking 3000cc to 5000cc of water daily can indeed be excessive for many individuals, depending on factors such as body weight, activity level, and climate. The general recommendation for daily water intake is about 2 to 3 liters (2000cc to 3000cc) for most adults. Drinking too much water can lead to a condition called hyponatremia, where sodium levels in the blood become dangerously low, potentially harming kidney function. It’s essential to listen to your body and adjust your intake based on thirst and urine color—light yellow is typically a sign of adequate hydration.

2. Masturbation and Prostate Health: There is no conclusive evidence that masturbation leads to prostate enlargement or prostatitis (inflammation of the prostate). However, excessive sexual activity, including masturbation, can lead to temporary discomfort or irritation. If you’re experiencing symptoms such as pain or discomfort, it might be beneficial to take a break and observe if symptoms improve. If issues persist, consulting a healthcare provider is advisable.

3. Lymph Nodes in the Groin: Finding lymph nodes in the groin area is not uncommon. Lymph nodes can swell due to various reasons, including infections or inflammation. The sizes you mentioned (1.1-1.2 cm and 0.5-0.7 cm) are within a range that can be considered normal, especially if there are no accompanying symptoms like pain or fever. However, if you notice any changes or if they become painful, it’s wise to consult a healthcare professional.

4. Urinary Tract Infections (UTIs) and Cancer Risk: A history of recurrent urinary tract infections does not directly increase the risk of developing urinary system cancers. However, chronic irritation or inflammation in the urinary tract can be a risk factor for certain types of cancer. It’s essential to maintain good urinary health and seek treatment for any recurrent infections.

5. Urine Color and Odor: The presence of a plastic-like odor in urine can be due to various factors, including dehydration, dietary choices, or certain medications. Changes in urine color, such as yellow-green, can also indicate dehydration or the presence of certain substances in the urine. If these changes persist, it would be wise to consult a healthcare provider for further evaluation.

6. Concerns About Cancer at Age 29: While the risk of developing urological cancers such as bladder, kidney, or prostate cancer increases with age, it is relatively low in individuals in their late twenties, especially if you maintain a healthy lifestyle. Regular check-ups and being aware of any unusual symptoms are essential for early detection.

7. Symptoms of Bladder Cancer: Blood in the urine (hematuria) is a common symptom of bladder cancer, but it is not always present. Other symptoms may include frequent urination, urgency to urinate, and pain during urination. If you experience any of these symptoms, it’s crucial to seek medical attention.

8. Urinary Stream Issues: A split urine stream can occur for various reasons, including anatomical variations or urinary tract infections. If you notice this consistently, or if you have difficulty fully emptying your bladder (feeling like you still have to urinate after finishing), it’s advisable to consult a healthcare provider for further evaluation.

In summary, while many of your concerns may not indicate serious health issues, it’s always best to consult with a healthcare professional for personalized advice and to address any persistent symptoms. Regular check-ups and being proactive about your health are key to maintaining well-being. Thank you for your questions, and I wish you the best in your health journey!
