Randomized Controlled TrialAnalgesic efficacy of paravertebral bupivacaine during percutaneous nephrolithotomy: an observer blinded, randomized controlled trial.
A unilateral paravertebral (PVB) block with catheter can provide extendable analgesia without physiological changes. The objective of this study was to assess the efficacy of PVB bupivacaine for providing perioperative pain relief in adults undergoing percutaneous nephrolithotomy (PCNL) under general anesthesia. ⋯ Unilateral PVB block with catheter provided effective perioperative analgesia for PCNL.

Randomized Controlled Trial Comparative StudyPercutaneous nephrolithotomy in the oblique supine lithotomy position and prone position: a comparative study.
To compare the safety, efficacy, and complications of percutaneous nephrolithotomy (PCNL) in the oblique supine lithotomy position vs the prone position in a randomized comparative study. ⋯ PCNL in both positions was equally successful with no significant differences in complications. PCNL in the oblique supine lithotomy position was superior to PCNL in the prone position regarding operative time, hospital stay, and effects on respiratory and cardiovascular status, making it more comfortable for patients and anesthesiologists. Morbidly obese patients, patients with cardiologic disorders, and patients with pulmonary obstructive airway disease need further studies to show if they would benefit from these differences. Additionally, it is more comfortable for the surgeon with little challenges added in the initial puncture.
