Urinary Tract Calculi VI: Surgical Management

639
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

1.9K
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.

Voiding Cystourethrography (VCUG) and Cystography are specialized radiographic procedures used to examine the structure and function of the bladder and urethra.Voiding Cystourethrography (VCUG)A Voiding Cystourethrogram (VCUG) is a diagnostic imaging procedure that assesses the anatomy and function of the lower urinary tract. It focuses on the bladder, bladder neck, and urethra, helping detect abnormalities such as vesicoureteral reflux (VUR)—the backward or reverse flow of urine into the...

Urologic Endoscopic Procedure: Cystoscopic Examination

3.8K
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...

Area of Science:

  • Vascular Surgery
  • Interventional Radiology

Background:

  • Transobturator bypass is an established but less common lower extremity revascularization technique.
  • It is often employed for patients with multiple failed bypasses, particularly those complicated by groin sepsis or infection.
  • The procedure presents significant technical challenges due to anatomical constraints.

Purpose of the Study:

  • To describe a novel surgical technique for transobturator bypass.
  • To highlight the utility of fluoroscopy in facilitating this challenging procedure.

Main Methods:

  • A successful transobturator bypass procedure is detailed.
  • The technique utilizes live fluoroscopy to guide the passage of the bypass tunneler and graft through the obturator foramen.

Main Results:

  • The described technique resulted in a successful transobturator bypass.
  • The use of fluoroscopy aided in navigating the anatomical constraints of the obturator foramen.

Conclusions:

  • Live fluoroscopy is a versatile tool in vascular surgery.
  • This surgical technique, combined with fluoroscopic guidance, has the potential to enhance the technical success rates of transobturator bypass procedures.
