What is Hydronephrosis?
Hydronephrosis is the swelling or enlargement of one or both kidneys caused by impaired drainage of urine. It usually occurs when urine cannot flow normally from the kidney to the bladder because of a blockage, narrowing or backward flow of urine. Kidney stones, urinary tract obstruction, enlarged prostate, congenital abnormalities, ureteral narrowing, pregnancy and certain cancers can cause hydronephrosis. Mild cases may resolve when the underlying problem improves, while prolonged or severe obstruction can damage kidney tissue and reduce kidney function.
What is the Importance of Timely Treatment?
Timely evaluation is important because persistent urinary obstruction can increase pressure within the kidney and, in severe or prolonged cases, cause permanent kidney damage or kidney failure. Treatment focuses on identifying and relieving the underlying obstruction, treating associated infection or other causes, and preserving kidney function. Some mild cases may only require monitoring, while significant obstruction may require urinary drainage or a procedure to correct the cause.
What are the Common Symptoms of Hydronephrosis?
- Pain in the side, back or abdomen that may radiate toward the groin
- Painful or burning urination
- Increased urinary frequency or urgency
- Difficulty passing urine or incomplete bladder emptying
- Blood in the urine
- Nausea or vomiting
- Fever or chills, particularly when infection is present
- Reduced urine output in significant obstruction
- Recurrent urinary tract infection
- Symptoms of reduced kidney function in advanced disease
Causes and Risk Factors of Hydronephrosis
Causes
- Hydronephrosis develops when urine drainage from the kidney is impaired. Common causes include kidney or ureteral stones, ureteral narrowing or scarring, enlarged prostate, urinary tract obstruction, congenital abnormalities, vesicoureteral reflux, urinary tract infections, pregnancy and tumors or cancers that compress or block the urinary tract.
- In some patients, obstruction may occur at the ureteropelvic junction or another point along the urinary drainage system.
Risk Factors
- Previous or recurrent kidney stones
- Conditions causing urinary tract obstruction
- Enlarged prostate in older men
- Previous pelvic or urinary tract surgery
- Ureteral scarring or narrowing
- Recurrent urinary tract infections
- Vesicoureteral reflux or congenital urinary tract abnormalities
- Pregnancy
- Pelvic or urinary tract tumors
- Certain neurological or bladder-emptying disorders
- Previous radiation treatment involving the urinary tract or pelvis
Latest Research and Technologies in the Treatment of Hydronephrosis in Singapore
Recent advances in hydronephrosis management in Singapore include detailed ultrasound imaging, MAG3 renal scans to assess kidney function and urinary drainage, and minimally invasive surgical techniques. Singapore General Hospital offers robot-assisted laparoscopic pyeloplasty to correct obstruction at the junction between the kidney and ureter. At the National University Hospital, ultrasound and functional kidney assessments help guide monitoring and determine when surgery may be needed, particularly in children with congenital obstruction. Treatment is tailored to the underlying cause and severity of hydronephrosis.
Treatment options for Hydronephrosis
Nephrectomy : This is the surgical removal of a kidney and may be considered when long-standing hydronephrosis has caused severe, irreversible loss of kidney function, particularly when the affected kidney contributes little or no useful function and is associated with recurrent infection, persistent pain, stones, or other complications.
Cost Start From 19000Explore Options
Surgery to correct an obstruction: Procedures may be needed for ureteral narrowing, ureteropelvic junction obstruction or other structural abnormalities.
Percutaneous nephrostomy: A drainage tube is inserted through the skin into the kidney when urine needs to be drained directly, including in selected urgent situations.
Treatment of kidney or ureteral stones: Depending on the stone's size and location, treatment may include observation, selected medicines to help stone passage, shock-wave lithotripsy or endoscopic stone removal.
- Clinical assessment:
- Urological Evaluation: A detailed history assesses flank or abdominal pain, urinary frequency, urgency, painful urination, reduced urine output, blood in the urine, recurrent infections, previous kidney stones, urinary procedures and other conditions that may cause obstruction.
- Kidney Function Assessment: Blood tests such as serum creatinine and estimated glomerular filtration rate (eGFR) help determine whether urinary obstruction has affected kidney function.
- Urine Assessment: Urinalysis can identify blood, protein, white blood cells and other findings that may suggest stones, infection or kidney disease.
- Assessment of the Cause: Doctors evaluate for kidney stones, ureteral narrowing, enlarged prostate, urinary reflux, congenital abnormalities, pelvic masses and other causes of obstruction.
- Functional Kidney Assessment: In selected patients, nuclear renal scans such as MAG3 may be used to evaluate how well each kidney functions and how efficiently urine drains from the kidneys.
- Imaging Tests:
- Renal Ultrasound: Often used as an initial imaging test to identify kidney swelling, urinary tract dilation, stones and some masses without radiation exposure.
- CT Scan: Can provide detailed images of the urinary tract and identify stones, obstruction, tumors, infections and other structural abnormalities.
- CT Urography: May be used when detailed evaluation of the urinary tract is required.
- MRI/MR Urography: Consider when detailed soft-tissue or urinary-tract imaging is needed or when radiation should be avoided.
- Nuclear Renal Scan: MAG3 or other renal scans can assess kidney function and urinary drainage.
- Cystoscopy and Ureteroscopy: These endoscopic procedures can directly examine the bladder and ureter and may also allow treatment of selected obstructions or stone disease.
MediRehab (a chain of Rehab centres, part of MediGence) provides comprehensive tele-rehabilitation services to support Hydronephrosis patients in Singapore. These Services include:
- Gradual Physical Activity: Patients can usually return to normal movement gradually after treatment, with activity restrictions based on the procedure and the treating team's advice.
- Hydration and Kidney-Supportive Care: Fluid intake should follow the treating clinician's recommendations, particularly when obstruction, reduced kidney function, or heart conditions are present. Patients with kidney stones may also receive individualised dietary guidance.
- Bladder and Urinary Function Support: Patients with underlying bladder-emptying problems may require follow-up, pelvic-floor or bladder-management strategies depending on the cause of obstruction.
- Long-Term Kidney and Stone Prevention Support: Patients with recurrent stones or chronic urinary tract problems may benefit from dietary counselling, physical activity, medication adherence and regular kidney-function and imaging follow-up.
- Medicines do not directly remove every cause of hydronephrosis, so treatment targets the underlying obstruction or condition. Pain-relieving medicines may be used when appropriate, while antibiotics are prescribed when a urinary tract or kidney infection is present. Depending on the cause, medicines may also be used to manage conditions contributing to urinary obstruction, such as symptoms related to an enlarged prostate. Medication selection should consider kidney function, the underlying cause and other health conditions.
