Unilateral hydronephrosis is a medical condition where one kidney becomes swollen due to a buildup of urine, often caused by a blockage in the urinary tract. This condition can be uncomfortable and potentially harmful if left untreated. In this article, we will simplify the definitions and details of unilateral hydronephrosis, including its types, causes, symptoms, diagnostic tests, treatments, and relevant medications.
Unilateral hydronephrosis is the swelling of one kidney caused by the accumulation of urine due to a blockage in the urinary tract. This blockage can occur at various points along the urinary system, from the kidney to the bladder. It is essential to understand the different aspects of this condition to effectively manage it.
Types of Unilateral Hydronephrosis
There are two main types of unilateral hydronephrosis:
- Acute Unilateral Hydronephrosis: This type develops suddenly and is often caused by a sudden blockage or obstruction in the urinary tract.
- Chronic Unilateral Hydronephrosis: This type develops gradually over time and is typically associated with long-term urinary tract issues, such as kidney stones or tumors.
Causes of Unilateral Hydronephrosis
Understanding what causes unilateral hydronephrosis is crucial for proper diagnosis and treatment. Here are 20 common causes:
- Kidney Stones: Small, hard deposits that can block the urinary tract.
- Ureteral Stones: Stones that form in the tubes connecting the kidneys and bladder (ureters).
- Tumors: Abnormal growths in the urinary system that can obstruct urine flow.
- Enlarged Prostate: In men, an enlarged prostate gland can press on the urethra, leading to blockages.
- Blood Clots: Clots can obstruct urine flow when they form in the urinary system.
- Urinary Tract Infections (UTIs): Infections can cause inflammation and blockage.
- Pregnancy: Pressure from an expanding uterus can obstruct the ureters.
- Scarring: Scar tissue from previous surgeries or injuries can narrow the urinary passages.
- Congenital Abnormalities: Birth defects in the urinary tract can lead to blockages.
- Bladder Dysfunction: Problems with bladder function can prevent proper urine flow.
- Neurological Disorders: Conditions affecting the nerves controlling the bladder and urinary system can lead to hydronephrosis.
- Cancer: Kidney or bladder cancer can obstruct urine flow.
- Hernias: Hernias can press on the ureters, causing blockages.
- Pelvic Organ Prolapse: When organs like the bladder or uterus sag into the vaginal canal, they can block the urinary tract.
- Fecal Impaction: Severe constipation can put pressure on the ureters.
- Inflammation: Inflammatory conditions, like interstitial cystitis, can affect urine flow.
- Medications: Some drugs can cause urinary retention and hydronephrosis.
- Trauma: Physical injuries to the urinary system can lead to blockages.
- Blood Vessel Abnormalities: Abnormal blood vessels near the urinary tract can compress it.
- Excessive Fluid Intake: Drinking too much water can overwhelm the kidneys, leading to swelling.

Diagnostic Tests for Unilateral Hydronephrosis
Diagnosing unilateral hydronephrosis involves various tests to determine the cause and severity of the condition. Here are 20 common diagnostic tests:
- Urinalysis: Analyzing a urine sample for blood, infection, and other abnormalities.
- Blood Tests: Checking for kidney function and infection markers.
- Ultrasound: Using sound waves to create images of the kidneys and urinary tract.
- CT Scan: Providing detailed cross-sectional images for a closer look at kidney and urinary tract structures.

- Intravenous Pyelogram (IVP): Injecting contrast dye into a vein to visualize the urinary system on X-rays.
- Renal Scintigraphy: Using a radioactive tracer to assess kidney function.
- Cystoscopy: Inserting a thin tube with a camera into the bladder to inspect the urinary tract.
- Urodynamic Testing: Assessing bladder function and urine flow.
- Retrograde Pyelogram: Injecting contrast dye directly into the ureters to visualize them.
- Voiding Cystourethrogram (VCUG): Assessing bladder and urethra function during urination.
- Biopsy: Collecting tissue samples for examination.
- Catheterization: Inserting a catheter to measure urine output and pressure.
