ANATOMY

Detailed explanation-1: -Ureters are long, narrow tubes that drain urine from your kidneys to your bladder. Normally one ureter leads from each kidney to your bladder. In the case of duplicated systems, two ureters drain a single kidney.

Detailed explanation-2: -Children with a duplex kidney (also called a duplicated collecting system) have two ureters coming from a single kidney. These two ureters can drain independently into the bladder or connect and drain as a single ureter into the bladder. Duplex kidneys can occur in one or both kidneys.

Detailed explanation-3: -Most of us are born with 2 ureters, the tube that drains the urine from each kidney into the bladder. But some babies are born with 2 ureters that drain a single kidney. In these cases, one ureter drains the upper part of the kidney and the second ureter drains the lower part of the kidney.

Detailed explanation-4: -Two ureters. These narrow tubes carry urine from the kidneys to the bladder. Muscles in the ureter walls continually tighten and relax forcing urine downward, away from the kidneys. If urine backs up, or is allowed to stand still, a kidney infection can develop.

Detailed explanation-5: -Print. A duplicated ureter occurs when two ureters form on the same kidney. A ureterocele is a small bulge in the ureter, usually in the end closest to the bladder. Both conditions may lead to ureteral obstruction.
