Urinary Tract Calculi VI: Surgical Management

850
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

2.8K
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.

Acute Pyelonephritis I: Introduction

1.2K
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...

Acute Pyelonephritis II: Diagnostic Studies and Management

668
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...

Urologic Endoscopic Procedure: Cystoscopic Examination

5.6K
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...

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...

Area of Science:

  • Urology
  • Pediatric Surgery
  • Nephrology

Background:

  • Kidney stones in infants present unique management challenges.
  • Minimally invasive surgical options are increasingly preferred for pediatric urolithiasis.

Purpose of the Study:

  • To evaluate the efficacy and safety of micro-percutaneous nephrolithotomy (micro-PNL) for treating kidney stones in infants.
  • To assess the stone-free rates and complication profile of micro-PNL in this specific pediatric population.

Main Methods:

  • Retrospective analysis of 24 infants (age < 2 years) who underwent micro-PNL for renal stones.
  • Inclusion criteria: stone size <20 mm, no urinary tract malformations or infection, no coagulopathy.
  • Stone clearance assessed by ultrasonography (USG) and KUB radiography; complications graded by Clavien system.

Main Results:

  • Mean patient age was 15.8 months, mean stone size 13.5 mm.
  • Mean operative time: 53.7 min; mean fluoroscopy time: 1.4 min; mean hospital stay: 2.5 days.
  • Overall stone-free rate was 83.3% (20/24 patients); minor complications (renal colic, fever) occurred in 6 patients; no transfusions needed.

Conclusions:

  • Micro-percutaneous nephrolithotomy (micro-PNL) is a safe and effective treatment for kidney stones in infants.
  • The procedure offers a high stone-free rate with a low complication burden in this young patient group.
