Role of Complementary Medicine (Music, Acupuncture, Acupressure, TENS and Audio-Visual Distraction) in Shockwave Lithotripsy (SWL): A Systematic Review From EAU Sections of Urolithiasis (EULIS) and Uro-Technology (ESUT)

Electroacupuncture combined with extracorporeal shock wave lithotripsy is beneficial for the expulsion of ureteral calculi: a prospective randomized trial

PURPOSE

To evaluate the therapeutic efficacy and safety of electroacupuncture (EA) combined with extracorporeal shock wave lithotripsy (ESWL) in treating ureteral calculi.

METHODS

This prospective randomized controlled trial included 207 patients with ureteral calculi who were randomly allocated to an experimental group that underwent EA plus ESWL (n = 95) and a control group that underwent only ESWL (n = 112). Imaging examinations were performed at 1, 2, and 4 weeks after the operation, followed by comparing the stone-clearance rate, time to first stone expulsion, and incidence of major complications between the two groups.

RESULTS

The stone-clearance rates at 1 (59.1 vs. 37%, P = 0.002), 2 (86.4 vs. 59.3%, P = 0.000), and 4 (90.9 vs. 77.8%, P = 0.013) weeks after the operation in the experimental group were significantly higher than those in the control group. The time to first stone expulsion in the experimental group was significantly lower than that in the control group (1.29 ± 1.55 vs. 2.45 ± 3.11 days, respectively; P = 0.001). However, we found no difference in the incidence of major complications between the two groups (15.9 vs. 17.6%, P = 0.754).

CONCLUSION

EA-assisted ESWL significantly improved stone clearance and shortened the time to stone expulsion without elevating the complication risk. However, a large-scale multicenter, prospective study is required to corroborate our conclusions.

Efficacy of acupuncture for pain relief in patients receiving extracorporeal shock wave lithotripsy: a meta-analysis of randomized controlled studies

Background

This meta-analysis aimed at investigating the efficacy of acupuncture for pain relief in patients receiving extracorporeal shock wave lithotripsy (ESWL).

Methods

Randomized controlled trials comparing the efficacy of acupuncture with conventional treatments were retrieved from major electronic databases (e.g., MEDLINE, EMBASE, and Cochrane Library) until August 28, 2022. The primary outcome was the response rate (i.e., rate of pain relief), while secondary outcomes included stone-free rate, satisfaction rate, duration of ESWL, peri-/post-procedural pain score, and risk of adverse events.

Results

Thirteen eligible studies involving 1,220 participants published between 1993 and 2022 were analyzed. Pooled results indicated that acupuncture had a better response rate compared to conventional treatments (RR = 1.17, 95% CI: 1.06-1.3, p = 0.003, seven trials, n = 832). Despite no difference in ESWL duration (MD = 0.02 min, 95% CI: -1.53 to 1.57, p = 0.98, three trials, n = 141), stone-free rate (RR = 1.11, 95% CI: 1-1.25, p = 0.06, six trials, n = 498), and satisfaction rate (RR = 1.51, 95% CI: 0.92-2.47, p = 0.1, three trials, n = 334) between the two groups, the acupuncture group had a lower risk of adverse events (RR = 0.51, 95% CI: 0.33-0.79, p = 0.003, five trials, n = 327), peri- (MD = -1.91 points, 94% CI: -3.53 to -0.28, p = 0.02, four trials, n = 258 patient) and post-procedural (MD = -1.07, 95% CI: -1.77 to -0.36, p = 0.003, four trials, n = 335) pain score.

Conclusion

The results of this meta-analysis showed that the use of acupuncture in patients receiving ESWL was associated with a higher pain relief rate and a lower risk of adverse events, suggesting feasibility of its use in this clinical setting.

The Use of a Virtual Reality Device (HypnoVR) During Extracorporeal Shockwave Lithotripsy for Treatment of Urinary Stones: Initial Results of a Clinical Protocol

OBJECTIVE

To assess the impact of a Virtual Reality Device (VRD, HypnoVR, Strasbourg, France) on patient-reported pain and anxiety during extracorporeal shockwave lithotripsy (ESWL).

MATERIALS AND METHODS

We enrolled 30 patients submitted to ESWL for urinary stones. Patients with either epilepsy or migraine were excluded. ESWL procedures were performed using the same lithotripter (Lithoskop; Siemens, AG Healthcare, Munich, Germany) at a frequency of 1 Hz delivering 3000 shock waves per procedure. The VRD was installed and started 10 minutes before the procedure. Tolerability of pain and treatment-related anxiety represented the primary efficacy outcomes and were evaluated using: (1) a visual analogue scale (VAS), (2) the short version of the McGill pain questionnaire (MPQ), and (3) the short version of the surgical fear questionnaire (SFQ). Secondary outcomes were VRD ease of use and patient satisfaction.

RESULTS

Median (IQR) age was 57 (51-60) years and body mass index (BMI) was 23 (22-27) kg/m². Median (IQR) stone size was 7 (6-12) mm with a median (IQR) density of 870 (800-1100) HU. Stone location was kidney in 22 (73%), and ureter in 8 (27%) patients. Median (IQR) extra time for installation was 6.5 (4-8) minutes. Overall, 20 (67%) patients were at their first ESWL treatment. Side effects were experienced by only 1 patient. Comprehensively, 28 (93%) patients would recommend and would use VRD again during ESWL.

CONCLUSION

VRD application during ESWL is safe and feasible. The initial report from patients is positive in terms of pain and anxiety tolerance. Further comparative studies are needed.

Virtual reality for pain control during shock wave lithotripsy: a randomized controlled study

PURPOSE

Although external shock wave lithotripsy (SWL) is an outpatient procedure generally not requiring anesthesia or sedation, patients may experience pain during the procedure. The aim of this study is to evaluate whether a virtual reality device is effective in reducing patient-reported pain during the procedure, consequently leading to exposure to higher energy levels and better clinical outcomes.

METHODS

Inclusion criteria for SWL were according to the latest EAU guidelines on urolithiasis. Patients were randomized 1:1 in two groups (SWL with VR and SWL without VR). The primary outcome of this randomized, controlled study (RCT) was an overall difference in pain levels determined by VAS-scores. Secondary outcomes were differences in comfort levels, determined by Likert-scale scores, clinical success and total delivered energy.

RESULTS

Between January 2019 and September 2021, we enrolled 166 patients; 84 were randomized to the control arm and 82 to the VR arm. Patients without VR experienced significantly more pain compared to the VR group (mean VAS-score = 4.94 vs 4.01; p = 0.011). The mean total delivered energy was significantly higher in the VR group compared to the control group (55.2 J vs. 48.8 J; p = 0'037). No significant differences in comfort levels and clinical success were found.

CONCLUSION

This study supports the use of VR as a method of pain relief during shock wave lithotripsy. Higher energy levels can be achieved during the treatment while comfort levels remained equal; this however did not lead to improved clinical success.

Effect of media distraction (audio-visual and music) for pain and anxiety control in patients undergoing shock-wave lithotripsy: A systematic review and meta-analysis

Audio-visual (AV) or music distraction may be used to reduce pain during several healthcare procedures. The present manuscript is a systematic review and meta-analysis to assess the effectiveness of media distraction in reducing pain and anxiety in extracorporeal shock wave lithotripsy (ESWL) patients. The PubMed, Embase, Scopus, BioMed Central, Ovoid and CENTRAL (Cochrane Central Register of Controlled Trials) databases were screened for studies assessing the role of media distraction (music/AV media) in reducing pain and anxiety of ESWL patients. Data were summarized using the mean difference (MD) with 95% confidence intervals (CI). A total of 11 randomized controlled trials were included. Pooled analysis indicated a statistically significant difference in pain outcomes with media distraction [mean difference (MD): -1.18; 95% CI: -2.35, -0.01; I²=96.8%)]. Subgroup analysis indicated that both AV media (MD: -2.94; 95% CI: -4.70, -1.17; I²=79.2%) and music (MD: -0.86; 95% CI: -1.37, -0.35; I²=62.5%), led to significant reduction in pain outcomes. Pooled analysis indicated a statistically significant reduction of anxiety scores with the use of media distraction (MD: -3.91; 95% CI: -6.44, -1.38; I²=77.7%). To conclude, the present review suggests that media distraction in the form of AV media or music may be beneficial in reducing the pain and anxiety of patients undergoing ESWL. Evidence is, however, weak considering the small effect size, confidence intervals being close to zero, and instability of the results on sensitivity analysis. In clinical practice, media distraction may be used during ESWL as a nursing intervention, but a clinically important reduction of pain and anxiety may not be expected.
