DISORDERS OF THE URETERS AND BLADDER (Ureteral stricture).

The right and left ureters carry urine from the right and left kidneys to the urinary bladder.

URETERAL STRICTURE:
 Occasionally a narrowing or stricture occurs in one ureters, interfering with the normal flow of the urine. Narrowing may be the result of damage to the lining from the presence or passing of a kidney stone or from some external pressure as from an enlarging tumor. The  symptom - pain in the lower back which travels to the region of the groin - may vary from a dull ache to almost intolerable pain.

What your physician can do. He may decide to periodically dilate or stretch the narrowing by passing a catheter, using a cystoscope, from the bladder up the ureter. When this method is not feasible, he may remove the kidney and ureter on the affected side, but only if the opposite ureter and kidney are functional.
