Abstract

Insights

Fungal pyelonephritis is common in preterm infants, with Candida albicans as the primary cause. Percutaneous nephrostomy and antifungal treatment offer effective management for this serious infant kidney infection.

Area of Science:

  • Pediatric Nephrology
  • Mycology
  • Neonatology

Background:

  • Fungal pyelonephritis is a rare but serious kidney infection.
  • Preterm and low birth weight infants are particularly vulnerable.

Purpose of the Study:

  • To investigate the clinical characteristics and management strategies for fungal pyelonephritis in infants.
  • To evaluate treatment outcomes and long-term prognosis.

Main Methods:

  • Retrospective analysis of 5 infant cases with fungal pyelonephritis.
  • Inclusion of clinical data, laboratory findings, imaging features, and treatment regimens.
  • Follow-up assessment of growth, development, and renal function.

Main Results:

  • All 5 cases involved preterm, low birth weight infants.
  • Unilateral or bilateral involvement with acute renal failure observed.
  • Imaging revealed fungus balls; urine cultures confirmed Candida albicans.
  • Percutaneous nephrostomy, irrigation, and antifungal agents led to good prognosis in most cases.
  • Survivors showed normal growth and development without urinary system malformations.

Conclusions:

  • Fungal pyelonephritis frequently affects preterm infants, with Candida albicans being the predominant pathogen.
  • Percutaneous nephrostomy and drainage are crucial for relieving urinary obstruction and controlling infection.
  • Early diagnosis and prompt treatment are vital for favorable outcomes in affected infants.

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...

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 as Proteus,...

Preoperative ManagementThe primary goals of preoperative management in kidney transplantation are to optimize the patient’s metabolic state and prepare them for surgery through diet adjustments, necessary dialysis, and tailored medical treatment. This phase also involves comprehensive infection screening and patient education about the surgical procedure and postoperative care to improve outcomes and adherence.Medical ManagementA comprehensive evaluation is required for both the living donor...

Urinary Tract Calculi VI: Surgical Management

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...

Imaging Studies V: Intravenous Urography and Retrograde Pyelography

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.

Urinary Tract Infection IV: Nursing Management

In managing urinary tract infections (UTIs) in nursing, a comprehensive assessment is essential. Begin by gathering subjective data, such as the patient’s complaints of dysuria (painful urination), urinary frequency, urgency, suprapubic pain, and any lower abdominal discomfort. This information can be complemented by questions regarding previous UTIs, sexual activity, and personal hygiene practices, which can provide insight into risk factors. Objective assessment should focus on signs like...
