Insights

Endoscopic subureteric injection of polytetrafluoroethylene paste (Polytef) offers an 80% cure rate for pediatric refluxing ureters after two treatments. While effective and minimally invasive, long-term safety and efficacy require further investigation.

Area of Science:

  • Pediatric Urology
  • Minimally Invasive Surgery
  • Biomaterials in Medicine

Background:

  • Vesicoureteral reflux (VUR) is a common condition in children, potentially leading to kidney infections and damage.
  • Endoscopic treatment offers a less invasive alternative to surgery for VUR.

Purpose of the Study:

  • To evaluate the efficacy and safety of endoscopic subureteric injection of polytetrafluoroethylene paste (Polytef) for treating primary VUR in children.
  • To determine the success rate and complication profile of this minimally invasive procedure.

Main Methods:

  • A cohort of 34 children with 40 primary refluxing ureters underwent endoscopic subureteric injection of Polytef.
  • Injected volumes ranged from 0.1 to 0.8 ml (mean 0.3 ml).
  • Success was defined as complete resolution of reflux; a second injection was permitted if needed.

Main Results:

  • A single injection successfully treated reflux in 26 ureters (65%).
  • Reflux grade improved in 9 additional ureters.
  • An overall cure rate of 80% was achieved after a second injection in 7 ureters.
  • One case of self-limiting ureteric obstruction was the sole complication.

Conclusions:

  • Subureteric Polytef injection is a quick, easy, and effective endoscopic treatment for pediatric VUR.
  • The procedure demonstrates a high initial success rate and an 80% overall cure rate after a second injection.
  • Long-term efficacy and safety of subureteric Polytef injection in children warrant further study and reservation.

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 III: Medical Management

The diagnosis of renal calculi involves several imaging techniques, including non-contrast CT scans and ultrasound. These methods help visualize kidney stones, assess their size and location, and detect possible obstructions. Additionally, Measuring urine pH is useful for diagnosing specific stone types, such as struvite (alkaline pH) and uric acid stones (acidic pH). Cystine stones are primarily linked to cystinuria, a genetic condition. A urinalysis helps detect blood in the urine (hematuria)...

Procedures for Kidney StonesMedical intervention is necessary when kidney stones or renal calculi are too large to pass spontaneously (typically greater than 5 millimeters) when stones are accompanied by symptomatic infection (such as fever or pyelonephritis), when they impair kidney function, or when they cause persistent symptoms like severe pain, nausea, or urinary retention. Additionally, patients with only one kidney or those who cannot be treated with medical management also require...

IntroductionIntravenous Urography (IVU) and Retrograde Pyelography (RP) are important diagnostic imaging techniques used to evaluate the urinary system. These methods help identify structural abnormalities, obstructions, and functional issues in the kidneys, ureters, and bladder. Both procedures use iodine-based contrast media to enhance the visibility of urinary tract structures on X-ray images, though they differ in their methods and indications.1.
