Urinary Tract Calculi VI: Surgical Management

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...

Urinary Tract Calculi II: Pathophysiology and Clinical Manifestations

Renal calculi, commonly termed kidney stones, are crystalline solid masses that form in the kidneys but can occur at any point within the urinary system, encompassing the kidneys, ureters, bladder, and urethra.The pathophysiology of renal stones involves several key factors: supersaturation of the urine with stone-forming constituents, changes in urine pH, a decrease in urine volume, and the presence of substances that promote or inhibit stone formation.Supersaturation of Urine: This is the...

Area of Science:

  • Oral and Maxillofacial Surgery
  • Prosthodontics
  • Reconstructive Surgery

Background:

  • Maxillary defects, often resulting from cleft palates or tumor resection, can lead to significant functional and aesthetic impairments.
  • These defects create openings into the nasopharynx, affecting speech, eating, and drinking.
  • Current treatments focus on restoring oral function and patient appearance.

Observation:

  • Intraoral defects necessitate specialized interventions to prevent food or liquid from entering the oronasal and oroantral cavities.
  • Obturators serve as prosthetic devices to manage these defects, allowing for improved mastication and deglutition.
  • This review examines three distinct clinical scenarios where obturators are employed.

Findings:

  • The successful application of an obturator in a specific clinical case highlights their efficacy in managing maxillary defects.
  • An alternative technique for fabricating hollow bulb obturators is presented, offering potential advancements in prosthetic design.
  • Obturators significantly improve the quality of life for patients by restoring basic functions and mitigating aesthetic concerns.

Implications:

  • Effective management of maxillary defects with obturators can lead to substantial improvements in patient speech and appearance.
  • The use of obturators facilitates normal eating and drinking, reducing the risk of aspiration and improving nutritional intake.
  • Further research into fabrication methods may lead to more efficient and customized obturator solutions for diverse patient needs.
