Urinary Tract Calculi VI: Surgical Management01:25

Urinary Tract Calculi VI: Surgical Management

941
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...

Acute Pyelonephritis II: Diagnostic Studies and Management

750
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...

Imaging Studies V: Intravenous Urography and Retrograde Pyelography

3.2K
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...

Imaging Studies I: Kidney, Ureter, and Bladder Studies

792
Kidney, Ureter, and Bladder (KUB) StudiesKidney, Ureter, and Bladder (KUB) studies are standard diagnostic imaging procedures used to assess the anatomy of the urinary system. They are commonly utilized for patients experiencing abdominal pain or urinary symptoms. By using a simple X-ray of the abdomen, KUB studies can reveal structural and pathological abnormalities within the kidneys, ureters, and bladder. These studies are particularly valuable in diagnosing kidney stones, urinary...

Imaging Studies II: Ultrasonography

821
IntroductionUltrasonography, or renal ultrasound, is a noninvasive medical imaging technique that uses high-frequency sound waves to visualize the kidneys, ureters, bladder, and surrounding tissues.Indications for Urinary System UltrasonographyUrinary system ultrasonography is indicated in various clinical scenarios, such as:Kidney Stones (Urolithiasis): To detect and monitor the size and presence of kidney or urinary tract stones.Hydronephrosis: To assess the dilation of the renal pelvis and...

Area of Science:

  • Urology
  • Nephrology
  • Surgical Innovation

Background:

  • Bilateral renal calculi pose a significant treatment challenge.
  • Simultaneous surgical intervention for bilateral stones requires careful evaluation.

Purpose of the Study:

  • To assess the efficacy and safety of same-session supine bilateral percutaneous nephrolithotomy (BPCNL).
  • To evaluate outcomes in patients with bilateral kidney stones treated with BPCNL.

Main Methods:

  • Retrospective analysis of 25 patients with bilateral renal stones (>2 cm) treated with same-session supine BPCNL.
  • Review of demographic data, stone characteristics, operative outcomes, and complications.
  • Computed tomography (CT) scans used for stone size measurement and stone-free rate assessment (residual fragments ≤2 mm).

Main Results:

  • A primary stone-free rate of 80% was achieved.
  • Postoperative creatinine levels showed transient significant differences, normalizing within 1 month.
  • Complication rates included Grade I (12%), Grade II (16%), and Grade IIIA (4%).

Conclusions:

  • Same-session supine BPCNL is a safe and effective treatment for bilateral renal calculi.
  • The procedure is technically demanding and best performed by experienced surgeons in tertiary care centers.
