Palpation of the kidney in the right abdomen?


Hello Doctor: I felt a lump to the right of my navel (it is more noticeable when standing and less so when lying down).
I went to a clinic for an ultrasound, and they informed me it is my right kidney.
I would like to ask: 1.
Is the kidney theoretically located just beneath the skin on the front of the abdomen? 2.
Is the kidney usually positioned in front of or behind the intestines? 3.
I can feel the right kidney by pressing with three to four fingers together from the front of my abdomen, to the right of my navel, and it feels like the kidney is just beneath the subcutaneous tissue, with no intestines covering it in front.
Is this normal? 4.
Is it necessary to go to a larger hospital for further confirmation in this situation? Thank you, Doctor!

Hello: 1) The right kidney can be palpated in thin individuals.
2) It is located posterior to the intestines.
3) The intestines are not easily palpable, making it difficult to assess whether they are normal.
4) If the clinic is confident that there are no abnormalities in the kidneys, observation is an option.
Wishing you good health.

Hello! Thank you for your questions regarding kidney location and the abdominal mass you've discovered. Let's address your concerns one by one.

1. Kidney Location: The kidneys are located in the retroperitoneal space, which is behind the peritoneum (the lining of the abdominal cavity). They are typically situated at the level of the lower ribs, with the right kidney usually positioned slightly lower than the left due to the presence of the liver. Therefore, while the kidneys are not directly beneath the skin, they can sometimes be palpated in certain individuals, especially if there is a significant anatomical variation or if the person is thin.

2. Position Relative to the Intestines: The kidneys are generally located behind the intestines. In a typical anatomical arrangement, the intestines lie anterior (in front of) the kidneys. However, in some cases, particularly in individuals with less abdominal fat or certain medical conditions, it may be possible to palpate the kidneys more easily.

3. Palpation of the Kidney: If you can feel a mass on the right side of your abdomen, it could be the kidney, especially if it is more prominent when standing. However, it is unusual for the kidney to be easily palpable in most individuals. If you are able to press down and feel it distinctly, it may indicate that the kidney is either enlarged or that there is a lack of surrounding adipose tissue. This could be a normal variant, but it is essential to consider other factors, such as any accompanying symptoms (pain, changes in urination, etc.).

4. Need for Further Evaluation: Given that you have already had an ultrasound that identified the mass as the right kidney, it may not be immediately necessary to go to a larger hospital unless you are experiencing concerning symptoms such as severe pain, changes in urinary habits, or any other alarming signs. However, if you have any doubts or if the mass seems to change in size or if you develop new symptoms, it would be prudent to seek further evaluation from a specialist, such as a urologist or a gastroenterologist.

In summary, while it is possible to palpate the kidney in some individuals, especially if there are anatomical variations, it is generally located behind the intestines in the retroperitoneal space. If you have concerns about the mass you are feeling, especially if it is new or associated with other symptoms, I recommend following up with your healthcare provider for further assessment. They may suggest additional imaging studies or evaluations to ensure everything is functioning correctly and to rule out any potential issues.

It's always better to err on the side of caution when it comes to your health. Regular check-ups and open communication with your healthcare provider are key to maintaining your well-being. Thank you for reaching out, and I hope this information helps clarify your concerns!
