Is a duplicated ureter rare?
Prevalence. Duplicated ureter is the most common renal abnormality, occurring in approximately 1% of the population.
Can a duplex kidney cause problems?

What is caval ureter?
POSTCAVAL ureter, also known as “circumcaval” or “retrocaval” ureter, is a congenital anomaly, primarily of the vascular system, that has been recognized and reported with increasing frequency in the past ten years.
What is a bifid system?
Bifid ureters fall into the first category, and may be defined as duplicated systems where two proximal branches drain the same pelvis, but join together distally to form one common ureteric branch prior to emptying into the bladder.
What is bifid renal pelvis?
A bifid renal pelvis is a congenital renal tract abnormality characterized as a duplication of the ureter (two ureters) that unite before emptying into the bladder.
Can a duplex kidney cause incontinence?
Diagnosis and symptoms of duplex kidney Symptoms include: Urinary tract infections (UTIs). An obstruction of the urinary tract resulting in poor urine flow. Urinary incontinence is marked by frequent leaking of urine.

What could cause a dilated ureter?
The causes of ureteral dilatation are divided into obstructive and nonobstructive. Dilatation of the right ureter with associated urinary tract infection in previously gravid women is often ascribed to pressure upon this structure by an incompletely involuted, aberrant, dilated, right ovarian vein [ 8
What are the symptoms of a dilated ureter?
Abdominal pain typically to the sides (flanks) as described under kidney pain location.
What is a duplex ureter?
In a duplex collecting system, the ureter with the ureterocele generally drains the top half of the kidney, while the other ureter drains the lower half. The ureter with the ureterocele may enter the bladder lower than the other ureter, which may cause a backflow of urine (reflux) into the higher ureter.
What is obstruction of ureter?
The most common symptom of an obstruction of the ureter is pain in the side, although sometimes obstructions cause no symptoms at all. Other symptoms may include nausea, vomiting, reduced urine output, and possibly a feeling of incomplete bladder emptying.
