Detailed explanation-1: -The left kidney is slightly longer than the right kidney (around 1.5 cm). Its anterior surface is linked with the stomach, left suprarenal gland, spleen, pancreas, and jejunum, whereas the posterior part is associated with the 11th and 12th rib, diaphragm, etc.

Detailed explanation-2: -The right kidney appears slightly larger than the left, accounting for this differential function.

Detailed explanation-3: -It is normal for the right kidney to be slightly larger than the left, although I have seen left kidneys be larger than the right and still be normal. There is no cause for concern unless one is said to be “small".

Detailed explanation-4: -The mean average pole-to-pole length of an adult human kidney is 10-13 cm. In general, the left kidney is slightly longer than the right.

Detailed explanation-5: -Hydronephrosis is swelling of one or both kidneys. Kidney swelling happens when urine can’t drain from a kidney and builds up in the kidney as a result. This can occur from a blockage in the tubes that drain urine from the kidneys (ureters) or from an anatomical defect that doesn’t allow urine to drain properly.
