Predicting epidural depth for kidney stone surgery
Part of Pain clinical trials.
This study looks at people who had a successful epidural for a kidney stone surgery (called percutaneous nephrolithotomy). It uses medical records to find factors that predict how deep the epidural needle goes, which can help make future procedures safer and more accurate.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 years old or older.
- You had a successful epidural placed using the midline approach (needle enters straight in the middle of the back).
- Your medical records clearly show the exact spine level and depth of the epidural needle.
- You did not have a dural puncture (accidental puncture of the spinal cord covering) during the procedure.
- You did not need additional general anesthesia because the epidural alone wasn't working well enough.

This trial compares a nerve block (erector spinae block) to standard pain medicine for controlling pain after kidney stone removal surgery (PCNL). It aims to see which method provides better pain relief with fewer side effects.
This study watches how resident doctors place epidural catheters (thin tubes placed near the spine to deliver pain medicine) during elective surgery. Researchers track how often the procedure works and what problems might occur, to improve training.
This trial compares how lying on your stomach versus your back during kidney stone removal affects blood flow and heart function. It may help doctors choose the safest position for you.
This trial studies using a small-needle spinal/epidural type pain medicine delivered to your back during a keyhole kidney removal. It may help control pain and reduce the need for stronger pain medicines during and after surgery.
This study compares two ways of getting a needle to the kidney for PCNL surgery (a procedure to remove stones). It aims to find which approach is safer and more effective for people with kidney stones between 1.5 and 3 cm.
This study compares two different depths for placing an epidural catheter (a tiny tube that delivers pain medicine) to see which provides better pain relief during labor. It uses a modern pump method called PIEB that gives regular small doses of medicine without needing to press a button.
