    Insights

    Electrophysiological studies reveal distinct ureter contractions in children with chronic pyelonephritis. Myostimulation improved ureter function, approximating it to healthy controls.

    Area of Science:

    • Pediatric Nephrology
    • Urology
    • Electrophysiology

    Context:

    • Chronic pyelonephritis affects ureter function in children.
    • Electrophysiological studies are crucial for understanding ureter dynamics.
    • Limited research exists on ureter electrophysiology in pediatric chronic pyelonephritis.

    Purpose:

    • To investigate ureter electrophysiological function in children with chronic pyelonephritis.
    • To compare ureter contraction patterns between patients and healthy controls.
    • To evaluate the efficacy of myostimulation in normalizing ureter function.

    Summary:

    • Electrophysiological study of ureter function (0.6–35 Hz) in 100 children (5–13 years) with chronic pyelonephritis versus 35 healthy controls.
    • Significantly reduced harmonic amplitudes at 1.4 Hz observed in pyelonephritis patients compared to controls.
    • Myostimulation treatment in pyelonephritis patients led to harmonic amplitudes closer to control group values.

    Impact:

    • Provides insights into the electrophysiological basis of ureter dysfunction in pediatric chronic pyelonephritis.
    • Highlights potential therapeutic benefits of myostimulation for improving ureter contractility.
    • Establishes a foundation for further research into non-invasive diagnostic and therapeutic strategies for pediatric urological conditions.

    Acute Pyelonephritis I: Introduction

    Pyelonephritis is a bacterial infection that primarily affects the renal parenchyma and collecting system, including the renal pelvis, tubules, and interstitial tissue of one or both kidneys. It can be classified as either acute—a sudden, severe infection—or chronic, which refers to long-term or recurrent kidney infections.The primary cause of acute pyelonephritis (APN) is bacterial infection, with Escherichia coli accounting for approximately 70-80% of cases. Other bacteria, such...

    Acute Pyelonephritis II: Diagnostic Studies and Management

    Introduction:For diagnosing acute pyelonephritis, a comprehensive patient history is collected to identify symptoms such as dysuria, frequent or urgent urination, flank pain, or costovertebral angle (CVA) tenderness that may suggest a kidney infection.Physical ExaminationDuring the physical examination, CVA tenderness is assessed. This involves gentle percussion over the costovertebral angle, where tenderness often indicates a kidney infection.Diagnostic TestsUrinalysis: Used to identify white...

    Urinary Tract Calculi II: Pathophysiology and Clinical Manifestations

    Renal calculi, commonly termed kidney stones, are crystalline solid masses that form in the kidneys but can occur at any point within the urinary system, encompassing the kidneys, ureters, bladder, and urethra.The pathophysiology of renal stones involves several key factors: supersaturation of the urine with stone-forming constituents, changes in urine pH, a decrease in urine volume, and the presence of substances that promote or inhibit stone formation.Supersaturation of Urine: This is the...

    Ureters01:22

    Ureters

    The ureters are retroperitoneal tubes located on either side of the vertebral column. They are responsible for transporting urine from each kidney to the urinary bladder. These tubes have thick walls and are approximately 25-30 cm long. Their diameter is around 10 mm at the renal pelvis, gradually narrowing to 1 mm as the ureter obliquely enters the posterior bladder wall through the ureteric orifices. The shape of these orifices is slit-like, which helps to prevent urine backflow toward the...

    AssessmentSubjective Data: Obtain a detailed health history, including any recent or chronic urinary tract infections, periods of immobilization, previous episodes of renal calculi, and medical conditions such as gout, benign prostatic hyperplasia, or hyperparathyroidism. Review the medication history for drugs that may influence stone formation, including allopurinol, analgesics, loop diuretics, or thiazide diuretics. Document the use of long-term indwelling catheters and any past surgical...

    Urinary Tract Infection I: Introduction

    Urinary tract infections (UTIs) impact various parts of the urinary system, including the kidneys, ureters, bladder, and urethra. These infections are generally bacterial, with Escherichia coli being the most common causative agent, often originating from the gastrointestinal tract. However, other bacteria, such as Staphylococcus saprophyticus, Klebsiella pneumoniae, and Proteus mirabilis, are also known to cause UTIs. The type, location, and underlying complexity of the UTI guide both...
