Duplex Kidney: Symptoms, Causes, and Treatment Options

Written by Medicover Team and Medically Reviewed by Dr Arun Kumar Donakonda , Nephrologist

A duplex kidney, also known as a duplicated collecting system, is a congenital condition in which one or both kidneys have two ureters instead of the typical single ureter.

This anatomical anomaly can lead to various complications, ranging from urinary tract infections (UTIs) to more severe kidney issues.

Understanding the causes, symptoms, and treatment options for duplex kidney is crucial for effective Management and improved quality of life.

What are the Duplex Kidney Symptoms and Warning Signs?

Recognize the symptoms early to seek timely care.

While many individuals with duplex kidneys may show no signs, complications can trigger noticeable symptoms. Recognizing these early can prevent long-term kidney damage.

Common Symptoms

Recurrent urinary tract infections (UTIs)
Frequent urination
Abdominal or flank discomfort

Severe Symptoms

Hematuria (blood in the urine)
Urinary incontinence
Nausea or vomiting (due to hydronephrosis)
Pain in the side or lower back

What Are the Different Types of Duplex Kidney?

Understand the structural differences to aid diagnosis and treatment.

Incomplete Duplication: Two ureters merge before entering the bladder.
Complete Duplication: Each ureter enters the bladder separately.
Unilateral Duplication: Only one kidney is affected.
Bilateral Duplication: Both kidneys are affected.

What Are the Common Causes and Risk Factors of Duplex Kidney?

Understand how and why this condition develops.

This condition begins during fetal development. Although many causes are not yet fully understood, several contributing factors have been recognized.

Causes

Abnormal fetal development of the ureteric bud
Genetic mutations affecting urinary tract formation

Risk Factors

Family history of congenital kidney anomalies
Maternal smoking or toxin exposure during pregnancy

How Duplex Kidney is Diagnosed?

Use precise diagnostics to detect and assess the condition.

Duplex kidney is often discovered during routine prenatal or postnatal imaging.

Common Diagnostic Tests

Ultrasound: Detects anatomical duplication and signs of hydronephrosis.
Voiding Cystourethrogram (VCUG): Identifies vesicoureteral reflux (VUR).
Magnetic Resonance Urography (MRU): Provides detailed structural imaging.
Renal Scintigraphy: Assesses kidney function and scarring.

At Medicover

We offer advanced imaging services and pediatric nephrology consultations to ensure accurate and early diagnosis.

What Are the Treatment Options for Duplex Kidney?

Outline available treatments and Medicover's care approach.

Treatment depends on the severity of symptoms and the presence of complications.
