Urinary Tract Calculi VI: Surgical Management

21
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

127
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. Intravenous Urography (IVU)Intravenous...

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

33
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...

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...

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,...

Background:

  • Percutaneous nephrolithotomy (PCNL) is a key procedure for kidney stone management.
  • The supine position for PCNL was initially described by Valdivia et al.

Purpose of the Study:

  • To evaluate the feasibility and benefits of supine percutaneous nephrolithotomy.
  • To highlight supine PCNL as an alternative for specific patient populations.

Main Methods:

  • Describes the technique of PCNL performed in the supine position.
  • Discusses the anatomical advantages and potential challenges of the supine approach.

Main Results:

  • The posterior tract in supine PCNL minimizes renal pelvic pressure, reducing fluid absorption.
  • Supine PCNL allows for gravity-assisted fragment clearance and spontaneous washout.
  • It is a viable option for patients with musculoskeletal issues preventing prone positioning.
  • Offers simultaneous flexible ureteroscopy capability.
  • Suction sheath use improves dust removal efficacy.

Conclusions:

  • Supine PCNL is a feasible and effective method for kidney stone treatment.
  • It provides significant advantages in fluid management and fragment clearance.
  • This position is particularly beneficial for patients unable to tolerate prone positioning.
