Introduction

To evaluate the clinical safety and feasibility for ultrasound guided paravertebral block anesthesia of percutaneous nephrolithotomy

Methods

Between December 2015 to May 2015, 58patients with renal or ureteral calculi came to our department and performed percutaneous nephrolithotomy. Men 33 cases, women 25 cases, aged 23-66, an average of 38.7 years. Stone of maximum diameter of 1.2 ~ 4.3 cm, the average (2.35 + 0.43) cm. 7 cases of previous ipsilateral renal surgery. All of the 58 patients were performedT10/T11?T11/T12 and T12/L1paravertebral block anesthesia guided by ultrasound. The time to identify the exact vertebra level and perform block were recorded. Subjective symptoms were monitored during operation. Muscular strength and pain score was checked after the operation

Results

Ultrasound guided thoracic-lumbar paravertebral block was performed successfully in all of the 58 patients with no complications. The time to identify the exact vertebra levelwas30±12s. The time to perform nerve block was 7±2min.None of the 58 patients complained pain during surgery. Operation time was 67 + 39min. After operation, ipsilateral lower extremity muscle strength grade IV in 9 cases, grade III in 46 cases, grade II in 3 cases. Postoperative hospital stay was 3 ~ 7 d, with an average (3.4 + 1.3) d. Stone-free rate84.5% (49/58).

Conclusions

Ultrasound guided paravertebral block can provide safe and reliable surgical anesthesia for percutaneous nephrolithotomy, which is worth widely clinical application and spread.
