N11.0
Nonobstructive reflux-associated chronic pyelonephritis
Clinical Classification Guidelines
Inclusion Terms
- Pyelonephritis (chronic) associated with (vesicoureteral) reflux
Excludes Type 1
- vesicoureteral reflux NOS (N13.70)
Medical Intelligence & Overview
Nonobstructive reflux-associated chronic pyelonephritis is a long-term type of kidney inflammation linked to a condition called vesicoureteral reflux. This occurs when urine flows backward from the bladder into the kidneys, leading to recurring infections and damage. Over time, this can cause scarring of the kidneys, impairing their ability to function properly. Recognizing and managing this condition is crucial for maintaining kidney health and preventing further complications.
Causes & Symptoms
Clinical Causes: Vesicoureteral reflux, a condition where the valve between the bladder and ureter doesn't function properly, allowing urine to flow backward Persistent urinary tract infections (UTIs) that lead to ongoing kidney inflammation Congenital abnormalities affecting the urinary tract Increased pressure in the bladder or ureters Other structural abnormalities of the urinary system
Key Symptoms: Flank pain or discomfort, often on one side Recurrent urinary tract infections Blood in the urine (hematuria) Frequent urination and urgency Pain or burning sensation during urination Fever and chills during infections Fatigue and malaise in more advanced cases
Diagnostic & Treatment
Diagnosis Path: Doctors diagnose this condition through a combination of medical history, physical examinations, and specialized tests. These may include urine analysis to detect infection, blood tests to assess kidney function, and imaging studies such as ultrasound or nuclear scans. Voiding cystourethrography (VCUG) might be performed to visualize the reflux of urine from the bladder into the kidneys, confirming the presence of vesicoureteral reflux and related kidney damage.
Treatment Protocols: Treatment aims to prevent further kidney damage and manage infections. It may involve:
