Assessment of the Abdomen III: Palpation01:23

Assessment of the Abdomen III: Palpation

4.0K
Palpation is a crucial tactile examination method for assessing abdominal organs and detecting conditions like tenderness, distention, masses, or fluid. It involves both light and deep palpation techniques, each serving specific diagnostic purposes. Light palpation helps identify tenderness and other surface-level indicators, while deep palpation locates and assess abdominal masses and organ boundaries. A skilled professional can gather valuable insights through palpation, including evaluating...

Area of Science:

  • Urology
  • Minimally Invasive Surgery
  • Surgical Techniques

Background:

  • Percutaneous renal surgery is a significant advancement in urology.
  • Kidney puncture can be achieved using fluoroscopy, ultrasound, or a combination.
  • Accurate kidney puncture is crucial for successful percutaneous procedures.

Purpose of the Study:

  • To describe a novel puncture technique for percutaneous renal surgery.
  • To simplify the kidney puncture process.
  • To reduce reliance on fluoroscopy and ultrasound during puncture.

Main Methods:

  • A perpendicular 90° puncture with a 20G spinal needle into the selected calyx under fluoroscopy.
  • Use of an 18G needle to follow the path from calyx to renal pelvis.
  • The 'needle kissing' technique aims to align the tips of both needles.

Main Results:

  • The described technique facilitates prone position puncture.
  • It provides valuable information via the thin needle.
  • It minimizes fluoroscopy for triangulation and avoids ultrasound for depth determination.

Conclusions:

  • The novel technique simplifies prone position percutaneous renal puncture.
  • It reduces the need for extensive fluoroscopic triangulation.
  • It offers an alternative to ultrasound for depth guidance.
