Lots of different things curve in. Something that curves inwards can also be called concave, a spoon is an example of something that is concave. A bowl is also concave and curves inward.

The concave side of the kidney is known as the hilum, where the renal artery, renal vein, ureter, and other structures enter and exit the kidney.
on the concave side of the kidney , which faces the vertebral column, lies a depressin called Hilus. it provides a placefr the renal vessels, nerves and the ureter to enter or leave the kidney.

The renal capsule, a fibrous covering, fits over the concave surface of each kidney.
The condition considering which Kidney is on the wrong side, is known as an Ectopic Kidney.
Renal hilium
Inner curved surface is known as concave mirror because inner side of the spherical mirror is polished to reflect the light is called concave mirror,and concave mirror is know because concave mirror converges parallel beam of light.
The concave side refers to the side of a curve that is curved inward or "caved in." It is the side that appears to be creating a hollow or depression in the surface. In geometry, concave shapes curve inward, like a cave.
the right side
The normal kidney location is towards the back of the abdominal cavity, just above the waist. One kidney is normally located just below the liver, on the right side of the abdomen and the other is just below the spleen on the left side. This is why when they are infected pain is often felt in the lower part of your back. In rare cases, however, one or both kidneys may be located much lower in the abdomen. This is not necessarily a problem except probably in the case of pregnancy. As the foetus begins to develop in the womb this could sometimes place pressure on the kidney which is located in the lower abdomen. The kidneys are dark-red, bean-shaped organs. One side of the kidney bulges outward (convex) and the other side is indented (concave). There is a cavity attached to the indented side of the kidney, called the Renal Pelvis, which extends into the urethra. Each Kidney is enclosed in a transparent membrane called the renal capsule; it is this renal capsule that helps to protect them against infections and trauma. Additionally, the kidney is divided into two main areas: A light outer area called the renal cortex, and a darker inner area called the renal medulla. Within the medulla there are 8 or more cone-shaped sections known as renal pyramids, furthermore, the area within these pyramids are known as renal columns. The normal kidney size of an adult human is about 10 to 13 cm (four to five in) long and about five to 7.5 cm (two to three in) wide. It is approximately the size of a conventional computer mouse. Additionally a kidney weighs approximately 150 grams. Kidneys weigh about 0.5 per cent of total body weight.
A concave lens has a curved surface that curves inward on both sides, causing light rays to diverge after passing through. In contrast, a plano-concave lens has one flat side and one curved concave side, which also causes light to diverge but with less optical power compared to a fully concave lens.
