Duplex kidney, also known as duplicated ureters or duplicated collecting system, is the most common birth defect related to the urinary tract. This occurs due to an incomplete fusion of the upper and lower pole of the kidney which creates two separate drainage systems from the kidney. Most people do not need treatment.

Is duplex kidney serious?
Duplex kidneys can occur in one or both kidneys. Duplex kidneys are a normal variant, meaning that they occur commonly enough in healthy children to be considered normal. They occur in 1 percent of the population, and most cause no medical problems and will require no treatment.
How do you treat a duplex kidney?
Treatments for duplex kidneys
- Nephrectomy kidney removal. …
- Heminephrectomy part of the affected kidney and duplicated ureter are removed.
- Ureteroureterostomy in the case of an ectopic ureter, it is split near the bladder and joined to the normal ureter, allowing urine from the upper kidney to drain as normal.
What is normal kidney split function?
The normal range for symmetric split function of each kidney is between 45-55% and changes of 5% are considered significant (28)(29) (30) . …
How does a kidney rupture?
Kidney rupture is similar to splenic rupture in that it is usually caused by a direct blow to the abdomen, side, or mid-to-low back which causes damage or a tear to the organ.
Can a damaged kidney repair itself?
It was thought that kidney cells didn’t reproduce much once the organ was fully formed, but new research shows that the kidneys are regenerating and repairing themselves throughout life. Contrary to long-held beliefs, a new study shows that kidneys have the capacity to regenerate themselves.
What problems can a duplex kidney cause?
There is reason for concern when a duplex kidney is associated with urologic conditions requiring treatment. Duplex kidney may result in urine flowing back into the kidney rather into the bladder and also may cause obstruction of urine.
Are duplex kidneys genetic?
Duplex kidneys are known to run in families so there is a hereditary component, but the exact genetic mechanisms are not always known.
Can we have 3 kidneys?
Having three kidneys is extremely rare, LiveScience says, with fewer than 100 cases reported in literature, according to a report in the Internet Journal of Radiology.

Is double ureter hereditary?
It can happen in boys or girls, but is more common in girls. There is also no proof that something during pregnancy causes it. It is known to be hereditary (passed down in a family). If you had an ectopic ureter, then each of your children has a one-half chance of having this duplicated system.
Can duplicated ureter cause kidney stones?
Complete ureteral duplication is more rarely seen compared to single ureter or partial duplication. Patients with ureteral duplication may potentially have urinary stones, ureterocele, vesicoureteral reflux (VUR) and obstructive uropathy.
Where is flank pain located?
Flank pain affects the area on either side of the lower back, between the pelvis and the ribs. Pain in the flanks can result from several conditions, diseases and injuries. Kidney stones, infection and muscle strains are common causes of flank pain.
How is split kidney function calculated?
Split renal function is then calculated by comparing the radioactive tracer accumulation from each side in the first 2 minutes, divided by the total accumulation in both kidneys over the same period.
What is DMSA and DTPA renal scan?
A DMSA scan is usually static imaging, while other radiotracers like DTPA and MAG3 are usually used for dynamic imaging to assess renal excretion. The major clinical indications for this investigation are. Detection and/or evaluation of a renal scar, especially in patients having vesicoureteric reflux (VUR)
What is baseline kidney function?
Renal impairment at baseline (estimated glomerular filtration rate [eGFR] <60 mL/min/1.73 m(2)) is the most important risk marker to predict the risk of contrast-induced nephropathy (CIN) in patients receiving iodinated contrast media.
What happens if your kidney explode?
In more serious cases, you may have trouble urinating, or when you do urinate, there is not much there. This can also cause symptoms of fever, blurred vision, nausea, and vomiting. If your kidneys have experienced trauma, you may have internal bleeding which can result in something fatal.
What happens if you tear your kidney?

How bad is a ruptured kidney?
Lacerated kidney treatment, complications, and recovery time A shattered kidney can be life-threatening and might need emergency surgery. Often, though, treatment is watchful waiting as the body allows the kidney to heal itself. Surgery is no longer routine, and patients with kidney injuries are treated with rest.

Drinking water regularly throughout the day helps your kidneys to function properly and stay healthy. Water is the best choice of fluid to drink throughout the day.
What are the 5 stages of kidney failure?

|---|---|---|
| Stage 2 | 60-89 | A mild decline in kidney function |
| Stage 3 | 30-59 | A moderate decline in kidney function |
| Stage 4 | 15-29 | A severe decline in kidney function |
| Stage 5 | <15 | Kidney failure or end-stage renal disease (ESRD) requiring dialysis |
What are the early warning signs of kidney failure?
Signs and symptoms of acute kidney failure may include:
- Decreased urine output, although occasionally urine output remains normal.
- Fluid retention, causing swelling in your legs, ankles or feet.
- Shortness of breath.

Can a duplex kidney cause pain?

What are the symptoms for stage 3 kidney disease?
Symptoms of stage 3 CKD
- Fatigue.
- Fluid retention, swelling (edema) of extremities and shortness of breath:

- Kidney pain felt in their back.
- Sleep problems due to muscle cramps or restless legs.
What causes double ureter?
Double ureter is caused by abnormalities in the branching pattern of the ureteric bud. In the case of complete duplication, the ureteral bud arises twice, resulting in a double ureter with a double opening into the urinary bladder.
What is a dromedary hump in kidney?
Dromedary hump is a prominent focal bulge on the lateral border of the left kidney caused by splenic impression, which can mimic renal neoplasm. It is a benign anatomic variant and exhibits the same imaging characteristics as adjacent renal cortex with normal blood flow pattern on Doppler sonography.

- Bilateral renal agenesis (BRA).
Can birth defects cause kidney disease?
Obstructive defects of the renal pelvis The urine backs up the ureters into the kidneys and, without treatment, can lead to persistent urinary tract infections and kidney failure. This common birth defect occurs in around one in 350 Victorian babies.
