Anatomical Positions

9.4K
In anatomy, several standard anatomical positions are used as references for describing the position and orientation of different body parts. These positions help provide a common frame of reference when discussing anatomical structures. The anatomical position is the standard reference point for describing the body's position and orientation. In this position:
The body is upright, facing forward, and standing erect.
The feet are parallel and flat on the floor.
The arms are hanging by the...

Summary

This study compared prone and flexed prone positions for percutaneous nephrolithotomy (PNL), finding both equally safe. The flexed prone position may offer benefits for obese patients and reduce operative time.

Area of Science:

  • Urology
  • Surgical Techniques
  • Nephrolithotomy

Background:

  • Percutaneous nephrolithotomy (PNL) is a common procedure for kidney stone removal.
  • Patient positioning is crucial for PNL safety and efficacy.
  • The study evaluates two common PNL positions: prone and flexed prone.

Purpose of the Study:

  • To compare the safety and efficacy of prone versus flexed prone positioning for PNL.
  • To identify potential advantages of each position, particularly in specific patient demographics.

Main Methods:

  • A randomized controlled trial involving 346 patients undergoing PNL.
  • Patients were stratified and randomly assigned to either the prone or flexed prone group.
  • Perioperative outcomes including stone-free rate, operative time, and complications were analyzed.

Main Results:

  • Both positions demonstrated comparable stone-free rates (92% vs 93.6%) and complication rates.
  • The flexed prone group showed a statistically significant lower mean BMI (29.9 vs 24.2) and a shorter average operative time (50.4 min vs 68.7 min).
  • Postoperative bleeding and pyelocaliceal perforation rates were similar between groups.

Conclusions:

  • The prone and flexed prone positions are equally safe for PNL.
  • The flexed prone position may be advantageous for obese patients and potentially reduces operative time.
  • Flexed prone positioning may facilitate better access to the pelvicalyceal system.
