Summary

This is a randomized control trial (meaning the selection is random as when flipping a coin) to assess the benefit of paravertebral blockade (PVB) in Percutaneous nephrolithotomy/nephrolithotripsy (PCNL) surgery.

Conditions

  • Nephrolithiasis

Interventions

OTHER

Paravertebral Block (PVB)

The T10, T11 and T12 paravertebral spaces on the operative side will be identified with ultrasound in all patients (Sonosite MicroMax, 2-5 MHz curvilinear probe). In the PVB group, a 90mm 22g Tuohy needle will be inserted in-plane with the live ultrasound image over the transverse process at each of these levels and 5 mL of 0.5% ropivacaine will be injected at each level.

OTHER

Saline

Ultrasonography and local infiltration of saline will only be performed
