Urinary tract obstruction in children is a serious condition where urine flow from the kidneys to the bladder or from the bladder outward is blocked or restricted. Left untreated, it can cause hydronephrosis, recurrent UTIs, child nephrolithiasis, bedwetting, and even permanent kidney damage.
With expert pediatric urology care, especially from specialists like Dr. Sadashiv Bhole in Nagpur, UTO can be accurately diagnosed and successfully managed, preserving your child’s kidney health and quality of life.
What Is Urinary Tract Obstruction?
- Blockage or narrowing anywhere in the urinary system: kidneys, ureters, bladder, or urethra
- Leads to urine buildup, backflow, or incomplete bladder emptying
- Can be congenital (from birth) or acquired later in childhood
- Untreated obstruction may cause infections, inflammation, and permanent renal scarring
Common Causes of Urinary Tract Obstruction in Children
- Ureteropelvic Junction (UPJ) Obstruction: blockage where ureter meets kidney
- Posterior Urethral Valves (PUV): congenital obstruction at bladder outlet, mostly in boys
- Vesicoureteral Reflux (VUR): backward urine flow causing swelling and infections
- Ureterocele: ballooning of ureter inside bladder wall
- Neurogenic bladder: bladder control problems due to nervous system issues
- Bladder outlet obstruction: structural narrowing, hypospadias, or strictures
- Stones: child nephrolithiasis causing physical blockage
- Tumors or external pressure (rare)
Symptoms of Urinary Obstruction in Children
- Foul-smelling urine
- Painful urination (dysuria)
- Difficulty starting or maintaining urine stream
- Bedwetting or daytime urinary incontinence
- Urinary retention—straining or inability to pass urine
- Fever with vomiting (suggesting infection)
- Visible swelling in abdomen or bladder area
- Blood in urine
- Poor growth, irritability, or feeding difficulties in infants
Note: Some children may be asymptomatic, especially with partial obstruction.
Complications of Untreated Urinary Tract Obstruction
- Hydronephrosis (kidney swelling)
- Recurrent pediatric UTIs
- Permanent kidney damage and scarring
- Urinary incontinence or voiding dysfunction
- Electrolyte imbalances
- Growth delays in infants and toddlers
Early diagnosis and treatment are critical to preserve kidney function and prevent lifelong complications.
Diagnosis of Pediatric Urinary Tract Obstruction
- Ultrasound (KUB) to detect kidney swelling, stones, or anatomical blockages
- Voiding Cystourethrogram (VCUG) to check for reflux or outlet obstruction
- Urodynamic studies for bladder function assessment
- MAG3 or DTPA renal scan to evaluate kidney drainage and function
- Urinalysis & culture to detect infections and blood in urine
- Special attention for newborns diagnosed prenatally with hydronephrosis
Treatment Options
Observation & Monitoring
- Minor obstructions without kidney damage may be carefully observed
- Regular ultrasounds and urine tests to monitor progression
- Close monitoring for infection or retention signs
Medications
- Antibiotic prophylaxis to prevent infections
- Drugs to relax bladder muscles or improve urine flow if neurogenic bladder is involved
Surgical Interventions
- Pyeloplasty: to correct UPJ obstruction
- Valve ablation: for posterior urethral valves
- Ureteral reimplantation: to fix abnormal ureter insertion or reflux
- Stone removal: in cases of nephrolithiasis causing blockage
- Robotic or laparoscopic approaches for minimally invasive precision
Recovery and Follow-Up
- Post-surgical imaging and renal function scans
- Bladder training for voiding dysfunction
- Ongoing pediatric nephrology consultations if kidney function is affected
- Lifestyle guidance on hydration, diet, and constipation management
When to Consult a Pediatric Urologist in Nagpur
- Repeated UTIs, especially with fever, foul-smelling urine, or painful urination
- Bedwetting, daytime wetting, or urinary incontinence
- Poor urinary stream or signs of urine retention
- Prenatal or postnatal diagnosis of hydronephrosis
- History of hypospadias, PUV, or kidney stones
- Signs of bladder distention, pain, or abnormal urination
Urinary tract obstruction in children can silently threaten kidney health if overlooked. Whether detected on ultrasound or suspected from symptoms like bedwetting, painful urination, or recurrent infections, timely and expert care is vital.
