Insights

Flexible ureteroscopy (FURS) with holmium laser lithotripsy effectively treats pediatric upper urinary tract stones. This safe procedure achieved an 89% stone-free rate in 100 children, with minor complications.

Area of Science:

  • Pediatric Urology
  • Endourology
  • Nephrolithiasis Treatment

Background:

  • Upper urinary tract stones in children pose a significant clinical challenge.
  • Flexible ureteroscopy (FURS) has emerged as a minimally invasive treatment option.
  • Holmium laser lithotripsy offers precise stone fragmentation capabilities.

Purpose of the Study:

  • To evaluate the efficacy and safety of FURS combined with holmium laser lithotripsy.
  • To assess the stone-free rate and complication profile in pediatric patients.
  • To identify factors influencing treatment outcomes in children with upper tract stones.

Main Methods:

  • Retrospective analysis of 100 pediatric patients undergoing FURS with holmium laser lithotripsy.
  • Preoperative stenting with a double-J stent was performed in all cases.
  • Data on operative parameters, stone characteristics, and postoperative outcomes were collected and analyzed.

Main Results:

  • An overall stone-free rate of 89% was achieved after a single operation.
  • Mean stone diameter was 1.49 cm; average operative time was 30.8 minutes.
  • The most common complications were postoperative hematuria (64%) and urinary tract infection (7.1%); no ureteral perforations occurred.

Conclusions:

  • FURS combined with holmium laser lithotripsy is an effective and safe treatment for pediatric upper urinary tract stones.
  • Stone size and staghorn calculi were significantly associated with the stone-free rate.
  • The procedure demonstrates a favorable safety profile with manageable complications in the pediatric population.

Urinary Tract Calculi I: Introduction

Renal calculi, or kidney stones, are solid deposits of minerals and salts formed inside the kidneys. In medical terminology, "calculus" refers to the stone itself, while "lithiasis" describes the process of stone formation. Depending on their location within the urinary system, these stones may be classified as either urolithiasis, when situated within the urinary tract, or nephrolithiasis, when located within the kidneys. Each term signifies the specific impact of the stone.Predisposition...

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...

Urinary Tract Infection II: Pathophysiology

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...

Anatomy of Respiratory System I: Upper Respiratory Tract

The upper respiratory tract plays a vital role in the respiratory system, comprising several structures that facilitate air intake and prepare air for the lungs. It also serves as the first line of defense against pathogens and particles. This tract includes the nose and nasal cavity, the oral cavity, the paranasal sinuses, and the pharynx, each with specific functions and features.
Nose and nasal cavity
The nose and nasal cavity represent the main external openings of the respiratory tract....

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 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...
