The Loop of Henle
The ability to form a concentrated urine depends on the functions of the kidneys, specifically the renal tubules and collecting ducts. These structures are responsible for reabsorbing water and solutes back into the body while removing waste products. Hormones like antidiuretic hormone (ADH) also play a crucial role in regulating water reabsorption and urine concentration.
The maximum urine concentration is limited by the osmotic gradient between the kidney tubules and the surrounding interstitium. The ability to concentrate urine depends on the proper functioning of the kidney's loop of Henle and collecting ducts to establish and maintain this osmotic gradient. Additionally, factors such as hydration status and certain medical conditions can also affect the maximum urine concentration.
The kidney consists of several key parts, including the renal cortex, renal medulla, and renal pelvis. The renal cortex contains nephrons, the functional units that filter blood and produce urine. The renal medulla houses the collecting ducts and helps concentrate urine by reabsorbing water and electrolytes. The renal pelvis collects urine from the nephrons and channels it into the ureter for excretion.
Antidiuretic hormone (ADH) concentrates the urine by increasing water reabsorption in the kidneys. It helps the body regulate water balance by decreasing the amount of water excreted in urine.
Urine concentration can be measured using a urine specific gravity test or a urine osmolality test. These tests help to assess the amount of solutes in the urine, which reflects the kidneys' ability to concentrate urine. High concentration levels may indicate dehydration, while low levels may suggest overhydration or kidney issues.

Urine with a relatively low amount of water in it.
It is urine's specific gravity that measures the kidney's ability to concentrate or dilute urine in relation to plasma.

Specific gravity (SG) is a measurement of the kidneys' ability to concentrate urine. The test compares the density of urine against the density of distilled water, which has an SG of 1.000. Because urine is a solution of minerals, salts, and compounds dissolved in water, the SG is a measure of the density of the dissolved chemicals in the specimen. As a measurement of specimen density, SG is influenced by both the number of particles present and the size of the particles. Osmolality is a more exact measurement and may be needed in certain circumstances. The range of urine SG depends on the state of hydration and varies with urine volume and the load of solids to be excreted under standardized conditions; when fluid intake is restricted or increased, SG measures the concentrating and diluting functions of the kidney. Loss of these functions is an indication of renal dysfunction. http://faculty.washington.edu/alexbert/MEDEX/Spring/TS3UA.htm
To improve your ability to concentrate urine effectively, you can stay hydrated, avoid excessive alcohol and caffeine consumption, and maintain a balanced diet. Additionally, getting regular exercise and managing stress can also help improve your kidney function and urine concentration.

Alcohol is a diuretic, which means it increases urine production. This can lead to more dilute urine, which appears clearer in color. Additionally, alcohol can affect the body's ability to concentrate urine, further contributing to its clarity.
The function of the bladder is to store and release urine.
