Creatinine is not reabsorbed by the nephron and is completely excreted in urine.
Ref: NCERT Class 11 Biology Chapter 16: Excretory Products and their Elimination Urine Formation - Reabsorption and Secretion
The Loop of Henle establishes an osmotic gradient, which helps in water reabsorption and urine concentration.
