Urinary Tract Calculi VI: Surgical Management

25
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

139
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.

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...

Acute Pyelonephritis II: Diagnostic Studies and Management

35
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...

Parentral Nutrition: Centeral and Peripheral Parental Nutrition

Parenteral Nutrition (PN) delivers essential nutrients directly into the bloodstream, bypassing the digestive system. It is commonly used for individuals with severe digestive disorders or conditions that prevent normal nutrient absorption.
PN can be administered through two primary routes:
1. Central Parenteral Nutrition (CPN):
CPN involves delivering a high concentration of nutrients through a large vein. This is typically achieved using a Peripherally Inserted Central Catheter (PICC) or,...

Summary

Most urologists worldwide prefer prone positioning for percutaneous nephrolithotomy (PCNL), using fluoroscopy for access and balloon dilation. However, many adapt their approach based on patient needs.

Area of Science:

  • Urology
  • Endourology
  • Surgical Techniques

Background:

  • Percutaneous nephrolithotomy (PCNL) is a key procedure for kidney stone management.
  • Global practice patterns for PCNL can vary significantly among surgeons.

Purpose of the Study:

  • To assess current worldwide practices in percutaneous nephrolithotomy (PCNL).
  • To understand the preferred techniques and variations among endourologists.

Main Methods:

  • A 22-question global survey was distributed to members of the Endourology Society.
  • The survey focused on surgeon demographics, practice setting, and PCNL procedural details.

Main Results:

  • 441 urologists responded, with most practicing in academic settings and having specialized fellowship training.
  • Prone positioning was the most common approach for PCNL, though multi-positional techniques were also used.
  • Urologists predominantly performed their own access under fluoroscopy, utilized balloon dilation, and employed various lithotripsy methods, with post-procedural drainage being common and tubeless PCNL rare.

Conclusions:

  • The majority of urologists favor prone positioning, fluoroscopic guidance for access, and balloon dilation for PCNL.
  • Surgeons demonstrate flexibility, adapting their PCNL strategies when clinically indicated.
