In the renal pelvis
Someone with highly concentrated urine may be dehydrated, and fluids may help.
From the original filtrate, a lot of much needed electrolytes (Sodium e.t.c) are reabsorbed (absorbed back into blood), a few substances secreted further into the urine, then loads of water reabsorbed to fine tune body water to exactly how much you need(as much as possible), making urine far more concentrated than the original filtrate.

Typically, summer temperatures cause people to become dehydrated. Dehydrated people produce concentrated urine.
Until the liquid reaches the renal pelvis, it is "glomerular filtrate," when it reaches the pelvis, it is called "urine"
The main difference between filtrate and urine is the chemical composition of the two. Filtrate has almost all the substance that blood plasma has except blood proteins while urine only contains waste substances.

Antidiuretic hormone(ADH) reabsorbs water from the collecting tubules of the kidney causing urine to become concentrated.

In fact, the kidney dose not receives the urine but it produces the urine by receiving the filtrate from the blood vessels . and the first part wich receives the filtrate is the " glomerus"
Nephrons. This includes the glomerulus where the blood stream encounters a connective tissue filter, the loop of Henle where the filtrate is concentrated and salts are exchanged and the collecting duct into which urine is collected.
