Ureteral Stricture

The kidney is made of two parts – the parenchyma (the outer portion of the kidney, which makes urine) and the collecting system (the inner portion of the kidney, which collects urine).  The ureter is a small tube that drains urine from the collecting system into the bladder. When it is time to urinate, urine leaves the bladder through the urethra.

A ureteral stricture refers to a ring of scar tissue that develops within the ureter – this can make it difficult for urine to drain from the kidney. The scarring can form for various reasons including

  • Kidney stones
  • Infections of the urinary tract
  • Abnormal urinary tract anatomy
  • Cancer of the bladder and/or ureter
  • Prior surgery on the urinary tract
  • The scarring can also form without any known prior cause

A ureteral stricture can cause

  • Pain
  • Kidney Infection
  • Development of kidney/ureteral stones
  • Issues with kidney function

  • Ureteroscopic dilation
  • Segmental Ureterectomy
  • Pyeloplasty
  • Ureteral Reimplant
  • Ureteroplasty
