Randomized Controlled Trial
Real-time ultrasound-guided PCNL using a novel SonixGPS needle tracking system.
SonixGPS is a successful ultrasound guidance position system. It helps to improve accuracy in performing complex puncture operations. This study firstly used SonixGPS to perform kidney calyx access in PCNL to investigate its effectiveness and safety. ⋯ Furthermore, the hemoglobin decrease was also obviously lower in the SonixGPS group than that in conventional US-guided group. SonixGPS needle tacking system guided PCNL is safe and effective in treating upper urinary tract stones. This novel technology makes puncturing more accuracy and can significantly decrease the incidence of relative hemorrhage and accelerate recovery.

Randomized Controlled Trial
The effect of local anesthetic infiltration around nephrostomy tract on postoperative pain control after percutaneous nephrolithotomy.
The objective of the study was to investigate the effect of a long acting local anesthetic infiltration around nephrostomy tract on pain control after percutaneous nephrolithotomy. Forty-six patients with kidney stones of >2 cm undergoing single access subcostal percutaneous nephrolithotomy (PCNL) were enrolled in the study. Patients were randomized to levobupivacaine (Group I) and saline (Group II) infiltration groups. ⋯ Ambulation time and duration of nephrostomy tube were also similar. Infiltration of nephrostomy tract site with levobupivacaine does not have a superior effect compared to saline on postoperative pain control in patients undergoing PCNL. To prolong analgesia, the effect of intermittent tract injections or continuous infusion of local anesthetics for the postoperative maintenance of the local anesthetic effect seems worth to investigate in future studies.
