Cephalad renal movement during percutaneous nephrostolithotomy

Area of Science:

• Urology
• Anatomy
• Medical Imaging

Background:

• Percutaneous nephrostomy involves accessing the kidney for stone removal.
• Kidney displacement during patient positioning is a significant surgical consideration.

Purpose of the Study:

• To quantify kidney positional changes from supine to prone positions.
• To assess the clinical implications of kidney ascent during percutaneous procedures.

Main Methods:

• Patient positioning changes from supine to prone.
• Measurement of kidney ascent using imaging techniques (implied).

Main Results:

• The majority of kidneys ascend an average of 2.2 cm.
• Kidney ascent is more pronounced on the right side.
• Ascent is more common in male patients.

Conclusions:

• Understanding kidney ascent is crucial for patient selection in percutaneous nephrostolithotomy.
• Knowledge of this anatomical variation aids in planning percutaneous access for renal and ureteral calculi.
