Obstruction that occurs anywhere along the upper urinary tract will lead to increased pressure within the structures of the kidney due to the inability to pass urine from the kidney to the bladder. Common causes of upper tract obstruction include obstructing stones and ureteropelvic junction (UPJ) obstruction caused by intrinsic narrowing of ...
These infection stones are commonly observed in people who have factors that predispose them to urinary tract infections, such as those with spinal cord injury and other forms of neurogenic bladder, ileal conduit urinary diversion, vesicoureteral reflux, and obstructive uropathies.
A urinary tract infection (UTI) is an infection that affects a part of the urinary tract. [1] Lower urinary tract infections may involve the bladder (cystitis) or urethra while upper urinary tract infections affect the kidney (pyelonephritis). [10]
When it affects the lower urinary tract it is known as a bladder infection (cystitis) and when it affects the upper urinary tract it is known as a kidney infection (pyelonephritis).

Obstruction of an opening or duct, interfering with normal flow and disrupting the function of the organ in question; Predisposition to infection (often due to disruption of normal flow) A number of important medical conditions are caused by stones: [citation needed] Nephrolithiasis (kidney stones)
Pyonephrosis (from Greek pyon 'pus' and nephros 'kidney' [1]) is a dangerous kidney infection that is characterized by pus accumulation in the renal collecting system. [2] It is linked to renal collecting system blockage and suppurative renal parenchymal destruction, which result in complete or nearly complete kidney failure. [3]

Ureteral stents are used to ensure the openness of a ureter, which may be compromised, for example, by a kidney stone or a procedure. This method is sometimes used as a temporary measure, to prevent ...
