Causes of PUJ Obstruction

Congenital Abnormalities: Most cases are present at birth due to abnormal development of the junction.
Scar Tissue: Previous surgeries, infections, or injuries can cause scar tissue that narrows the junction.
Blood Vessels: An abnormal blood vessel crossing the ureter can compress it, causing obstruction.

Effects of PUJ Obstruction

Hydronephrosis: The blockage can cause the kidney to swell due to urine buildup.
Pain: Patients may experience pain in the abdomen or back, especially after fluid intake.
Infections: Obstruction increases the risk of urinary tract infections (UTIs).
Kidney Damage: Prolonged obstruction can lead to loss of kidney function if not treated promptly.

Diagnosing PUJ Obstruction

Ultrasound: Used to detect swelling in the kidney.
CT Scan: Provides detailed images to confirm the location and severity of the obstruction.
Renal Scan: Assesses kidney function and the degree of obstruction.

Treatment Options

Observation: In mild cases, regular monitoring may be sufficient, especially in infants.
Surgical Intervention:
- Pyeloplasty: The most common surgical procedure, where the obstructed segment is removed, and the healthy ends are reconnected.
- Endopyelotomy: A minimally invasive procedure where the obstruction is cut open and the ureter is widened.
Stenting: In some cases, a stent may be placed temporarily to allow urine to flow freely.

Post-Treatment Care

Dr. Amit provides ongoing care post-surgery, including regular follow-ups and imaging studies to ensure the success of the treatment and prevent recurrence.
