Summary
Urinary tract infections (UTIs) are common after minimally invasive pyeloplasty (MIP) in children. Bacteria cultured from stents and urine are usually unrelated, suggesting routine stent culturing has low clinical value.
Area of Science:
- Pediatric Urology
- Infectious Diseases
- Surgical Outcomes
Background:
- Minimally invasive pyeloplasty (MIP) is increasingly used in children.
- Indwelling Double-J ureteral stents are common after MIP.
- Urinary tract infections (UTIs) are a known complication associated with foreign bodies like stents.
Purpose of the Study:
- To identify bacteria causing UTIs in children undergoing MIP with indwelling ureteral stents.
- To determine the relationship between bacteria cultured from urine and stents.
- To assess the clinical significance of routine stent culturing.
Main Methods:
- Retrospective review of 30 children (2.7 years median age) who underwent MIP (2014-2017).
- Urine and stent cultures were obtained at various time points.
- Patient demographics, stent types, and surgical details were recorded.
Main Results:
- 13% of patients developed febrile UTI, and 13% developed afebrile UTI.
- Stent cultures were positive in 63% of patients, but rarely matched urine cultures.
- No association found between UTI and gender, stent diameter, or indwelling duration.
Conclusions:
- UTIs occur in about a quarter of children post-MIP.
- Post-surgical urinary pathogens are typically unrelated to stent colonizers.
- Routine stent culturing offers low clinical significance; optimizing pre-operative antibiotic therapy may be beneficial.

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...

39
The pathophysiology of urinary tract infections (UTIs) encompasses several progressive stages, beginning with bacterial colonization and culminating in potential systemic complications if untreated. UTIs are primarily initiated by bacteria, such as Escherichia coli, which often originate from the gastrointestinal tract and migrate to the urinary system through the periurethral area. This migration can occur via several routes, including improper hygiene practices, sexual activity, or...

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...

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...

42
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...

A healthcare provider can diagnose a urinary tract infection (UTI) through several methods:Medical History and Symptoms: The provider will take a detailed medical history and ask about symptoms such as frequent urination, burning sensation during urination, and lower abdominal pain.Urinalysis: A clean-catch urine sample is collected in a sterile container and tested for the presence of bacteria, white blood cells (leukocytes), nitrites, blood, and protein. The presence of leukocytes and...
