Urinary Tract Calculi VI: Surgical Management

72
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

305
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.

Urologic Endoscopic Procedure: Cystoscopic Examination

650
Meaning of Cystoscopic Examination:Cystoscopy is an essential diagnostic tool in urology that is used to assess the structure and function of the genitourinary system. It provides a direct view of the urethra, bladder, and, in some cases, the ureteral openings. This procedure helps detect structural abnormalities, infections, cancers, and blockages in the urinary tract. There are two types of cystoscopy:Flexible cystoscopy is commonly performed in outpatient settings due to its less invasive...

Endoscopic Procedures V: ERCP

1.2K
Endoscopic Retrograde Cholangiopancreatography (ERCP) is a diagnostic procedure that combines endoscopy and fluoroscopy to diagnose and treat conditions related to the bile ducts, pancreatic ducts, and gallbladder. This procedure is beneficial for identifying and addressing blockages, gallstones, strictures, and tumors within the biliary or pancreatic systems. ERCP is both diagnostic and therapeutic, offering the ability to visualize and treat identified problems in one session.

Acute Pyelonephritis II: Diagnostic Studies and Management

75
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...

Area of Science:

  • Urology
  • Minimally Invasive Surgery

Background:

  • Percutaneous nephrolithotomy (PCNL) is the standard treatment for kidney stones larger than 2 cm.
  • Successful PCNL relies on creating a safe and effective nephrostomy tract.

Purpose of the Study:

  • To detail the step-by-step endoscopic guided approach for percutaneous nephrolithotomy (PCNL).
  • To provide a guide for creating a nephrostomy tract with direct endoscopic visualization.

Main Methods:

  • Description and video depiction of each surgical step in endoscopic guided PCNL.
  • Focus on direct observation during nephrostomy puncture, tract dilation, and sheath placement.

Main Results:

  • Direct endoscopic visualization enhances safety during nephrostomy tract creation.
  • This systematic approach facilitates routine PCNL procedures and minimizes injury risk.

Conclusions:

  • Endoscopic guided PCNL provides direct visualization for safe nephrostomy tract formation.
  • This technique optimizes access and reduces complications in PCNL procedures for kidney stones.
