Abstract
Background and Purpose
: Extracorporeal shockwave lithotripsy (SWL) is an effective noninvasive, outpatient method of stone clearance. In our unit, it is performed using a combination of oral analgesia and intravenous sedation, which allows us to treat to therapeutic levels in the vast majority of our patients. However, we have encountered patients who do not tolerate various elements of the analgesia protocol and thus cannot be treated to full effect. The options for these people are currently limited to either SWL under formal sedation or epidural or general anesthetic or the use of another technique of stone clearance, such as percutaneous nephrolithotomy, which may not be as appropriate, and again necessitates an anesthetic, an inpatient stay, or both.
Patients and Methods
: We describe three patients who had previously failed SWL who received acupuncture in place of standard analgesia prior to the next treatment.
Results
: All three patients were able to tolerate the procedure better and were treated at a higher level with more shocks than in the previous session. No side effects were noted.
Conclusions
: We propose that acupuncture may be considered in patients unable to take standard sedoanalgesia. It is a cost-effective, safe method of inducing sedation with analgesia and had no demonstrable side effects in our series. It provides an attractive alternative to the use of general or regional anesthetics in these patients.
