OBJECTIVE: To evaluate the efficacy of shockwave therapy, acupuncture, hyperthermia, biofeedback therapy, electrical nerve stimulation, magnetotherapy and ultrasound therapy in the treatment of chronic prostatitis/chronic pelvic pain syndrome(CP/CPPS), and to provide evidence-based support for clinical decision-making. METHODS: Two researchers independently searched PubMed, Web of Science, Embase, Cochrane Library, CNKI, Wanfang, VIP and Chinese Biomedical Literature databases for randomized controlled trials(RCTs) on the effects of different interventions on CP/CPPS from the establishment of the databases to August 2024. We evaluated the quality of the included literature and extracted the relevant data according to the Cochrane Handbook for Systematic Reviews of Interventions, followed by network meta-analysis using Revman 5.3, R 4.33 and Stata17 software. RESULTS: A total of 25 RCTs involving 1 794 cases were included. The results of network meta-analysis showed that electrical nerve stimulation, shockwave therapy, biofeedback therapy, magnetotherapy, ultrasound therapy and acupuncture were significantly superior to conventional medication and placebo in the total NIH-CPSI scores(P< 0.05), and so were electrical nerve stimulation and shockwave therapy to acupuncture and hyperthermia(P< 0.05), magnetic therapy to hyperthermia, and ultrasound therapy to placebo(P< 0.05). Shockwave therapy, biofeedback therapy, electrical nerve stimulation, magnetotherapy and ultrasound therapy achieved remarkably better clinical efficacy than conventional medication and placebo in the treatment of CP/CPPS, and so did shockwave therapy than electrical nerve stimulation, hyperthermia, ultrasonic therapy, magnetotherapy and acupuncture. CONCLUSION For the treatment of CP/CPPS, electrical nerve stimulation is advantageous over the other interventions in improving total NIH-CPSI scores, and shockwave therapy is advantageous in relieving pain symptoms and clinical efficacy. This conclusion, however, needs to be further verified by more high-quality clinical studies.

OBJECTIVE: To evaluate and compare the effects and outcomes of extracorporeal shock wave therapy (ESWT) and intra-articular injections of hyaluronic acid (HA) in patients with knee osteoarthritis (OA). METHODS: Of the 78 patients recruited for the study, 61 patients met the inclusion criteria. The enrolled patients were randomly divided into two groups: the ESWT group and the HA group. The ESWT group underwent 3 sessions of 1,000 shockwave pulses performed on the affected knee with the dosage adjusted to 0.05 mJ/mm² energy. The HA group was administered intra-articular HA once a week for 3 weeks with a 1-week interval between each treatment. The results were measured with the visual analogue scale (VAS), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), Lequesne index, 40-m fast-paced walk test, and stair-climb test (SCT). A baseline for each test was measured before treatment and then the effects of the treatments were measured by each test at 1 and 3 months after treatment. RESULTS: In both groups, the scores of the VAS, WOMAC, Lequesne index, 40-m fast-paced walk test, and SCT were significantly improved in a time-dependent manner (p<0.01). There were no statistically significant differences measured at 1 and 3 months after treatment between the two groups (p>0.05). CONCLUSION: The ESWT can be an alternative treatment to reduce pain and improve physical functions in patients with knee OA.

PURPOSE: To evaluate predictors of the success rate for one session of shock wave lithotripsy (SWL), focusing on the relationships between pretreatment hydronephrosis grade and one-session SWL success rates. MATERIALS AND METHODS: The medical records of 1824 consecutive patients who underwent an initial session of SWL for treatment of urinary stones between 2005 and 2013 were reviewed. After exclusion, 700 patients with a single, 4–20 mm diameter radiopaque calculus were included in the study. RESULTS: The mean maximal stone length (MSL) and skin-to-stone distance were 9.2±3.9 and 110.8±18.9 mm, respectively. The average values for mean stone density (MSD) and stone heterogeneity index (SHI) were 707.0±272.1 and 244.9±110.1, respectively. One-session success rates were 68.4, 75.0, 75.1, 54.0, and 10.5% in patients with hydronephrosis grade 0, 1, 2, 3, and 4, respectively. Patients were classified into success or failure groups based on SWL outcome. Multivariate logistic regression analyses revealed that MSL [odds ratio (OR) 0.888, 95% confidence intervals (CI): 0.841–0.934, p<0.001], MSD (OR 0.996, 95% CI: 0.995–0.997, p<0.001), SHI (OR 1.007, 95% CI: 1.005–1.010, p<0.001), and pretreatment hydronephrosis grade (OR 0.601, 95% CI: 0.368–0.988, p=0.043) were significantly associated with one-session success. CONCLUSION: Pretreatment grades 3 or 4 hydronephrosis were associated with failure of SWL in patients with a single ureteral stone. In the presence of severe hydronephrosis, especially hydronephrosis grade 4; physicians should proceed cautiously in choosing and offering SWL as the primary treatment for ureteral stone.

OBJECTIVE: To investigate the factors affecting prognosis of extracorporeal shockwave therapy (ESWT) for chronic refractory Achilles tendinopathy (AT). METHODS: Thirty-six patients (48 consecutive feet) with chronic AT (>6 months) and who underwent ESWT for ‘poor’ or ‘fair’ grade in Roles-Maudsley Score (RMS) after unsuccessful conservative treatment were included in the present study. A maximum of 12 sessions of ESWT were conducted until treatment success: RMS reached ‘good’ or ‘excellent’. Termination of ESWT for no response, or ‘poor’ or ‘fair’ grade was regarded as treatment failure. Immediate outcome, long-term outcome (telephone interview after mean 26 months), and factors affecting treatment success were analyzed. RESULTS: Numeric Rating Scale was significantly decreased at immediate and long-term follow-up. Success rate was 71.1% and 90.3%, respectively. Univariate logistic regression identified that immediate treatment success was associated with retrocalcaneal enthesophyte on X-ray (odds ratio [OR], 0.06; 95% confidence interval [CI], 0.01–0.28), pretreatment abnormal ultrasonography echogenicity within Achilles tendon (OR, 18.89; 95% CI, 2.08–171.96), mean duration of ‘post-treatment soreness’ (OR, 0.55; 95% CI, 0.33–0.94), and duration of ‘post-treatment soreness after first ESWT’ (OR, 0.06; 95% CI, 0.01–0.34). The duration of ‘post-treatment soreness after first ESWT’ was found to be the only factor associated with long-term success (OR, 0.32; 95% CI, 0.10–0.99). CONCLUSION: ESWT appears to be effective in achieving long-term success in chronic refractory AT. Immediate success was associated with absence of retrocalcaneal enthesophyte on X-ray, presence of pretreatment abnormal ultrasonography echogenicity, shorter mean duration of ‘post-treatment soreness’, and shorter duration of ‘post-treatment soreness after first ESWT’. The shorter duration of ‘post-treatment soreness after first ESWT’ was identified as the only positive prognostic parameter in achieving long-term success.

OBJECTIVE: To compare the effect of extracorporeal shock-wave therapy (ESWT) applied at the muscle belly and myotendinous junction on spasticity in the upper and lower limbs of chronic stroke patients. METHODS: Of the 151 patients, a total of 80 patients with stroke-induced spasticity on the elbow flexor and 44 patients on the knee flexor were enrolled for a prospective, randomized clinical trial. The patients were divided into control, muscle belly, and myotendinous junction groups, and a total of three ESWT sessions (0.068–0.093 mJ/mm², 1,500 shots) were conducted at one per week. A Modified Ashworth Scale (MAS) and Modified Tardieu Scale (MTS) were collected at the baseline and at 1 week after each session. RESULTS: After interventions, the MAS and MTS of both the belly and the junction groups showed positive effects from the ESWT on spasticity in the elbow and knee flexors, but the control group did not. The results also tended to improve after each session until the entire intervention was completed. However, there was no significant difference between the belly and junction groups. CONCLUSION: ESWT could be effective for treating chronic spasticity after stroke when applied to muscle belly or myotendinous junction.

BACKGROUND: Ultrasonography has been established as one of the important diagnostic tools in detecting and classifying ovarian masses. Several studies have been made in determining the sensitivity and specificity of the different scoring systems as to determining the malignancy of ovarian masses. In a tertiary hospital ultrasound diagnostic unit, three scoring systems are utilized namely Lerner, Sassone and IOTA simple rules.
OBJECTIVE: To determine and compare the sensitivity and specificity on the most utilized ultrasound scoring systems in determining malignancy of ovarian masses.
METHODS: A single center observational, analytical, cross-sectional study utilizing review of the transvaginal or pelvic ultrasound results of women with ovarian masses that were scored using Sassone, Lerner and IOTA Simple Rules in a tertiary hospital ultrasound diagnostics unit from January 2013 to June 2016 was done. The sensitivity, specificity, positive and negative predictive values of each scoring system utilized was determined and compared with the histopathologic result.
RESULTS: Out of the 111 ovarian masses that were included in the study, 44 ovarian masses were scored using Lerner Scoring system with a sensitivity, specificity, positive and negative predictive values of 100%, 65% 22.2% and 100%. 105 ovarian masses screened using Sassone Scoring System showed a sensitivity, specificity, positive and negative predictive values of 100%, 68%, 20.5% and 100%. A total of 33 out of the 111 ovarian masses were scored using the IOTA scoring system with a sensitivity, specificity, positive and negative predictive values of 100%, 85.6%, 55.5% and 100%.
CONCLUSION: IOTA simple rules had a high sensitivity and specificity compared to Sassone or Lerner Scoring System. However, we cannot fully conclude that individual specificity will be better than combined tests since there is limited number of ovarian masses analyzed.

BACKGROUNDRoughly focused extracorporeal shock waves therapy (ESWT) is characterized by a wide focal area, a large therapy zone, easy positioning, and less pain during treatment. The purpose of this study was to investigate the effects of roughly focused ESWT on the expression of osteoprotegerin (OPG) and bone morphogenetic protein-2 (BMP-2) in osteoporotic fractures in rats.

METHODSSeventy-two female Sprague-Dawley (SD) rats, 3 months old, were divided into sham-operated group (n = 6) and an ovariectomized (OVX) group (n = 66). Sixty OVX SD rats were used as a model of double proximal tibial osteotomy and inner fixation. The osteotomy site in the left tibia was treated with roughly focused ESWT once at an energy density of 0.26 mJ/mm2, 60 doses/min, and 2000 pact quantities. The contralateral right tibia was left untreated and served as a control. Expression of OPG and BMP-2 in the callus of the osteoporotic fracture area was assessed using immunohistochemistry, real-time polymerase chain reaction (PCR), and Western blotting analysis.

RESULTSBone mineral density (BMD) at the proximal tibia, femur, and L5 spine was significantly reduced after ovariectomy. BMD of proximal tibia was 12.9% less in the OVX group than that in the sham-operated group. Meanwhile, bilateral oophorectomy resulted in a lower trabecular bone volume fraction (BV/TV) in the proximal tibia of the sham-OVX animals. Three months after bilateral oophorectomy, BV/TV was 14.29% of baseline BV/TV in OVX legs versus 45.91% in the sham-OVX legs (P < 0.001). These data showed that the SD rats became a suitable model of osteoporosis, 3 months after they were OVX. Immunohistochemical analysis showed higher levels of BMP-2 and OPG expression in the treatment group than those in the control group. Compared with the contralateral controls, decreased expression of OPG and BMP-2 at 3 days after roughly focused ESWT, followed by a later increase at 7 days, was indicated by real-time PCR and Western blotting analysis. The OPG messenger RNA (mRNA) expression levels peaked at 6 weeks after the shock wave treatment, paired with a much earlier (at 4 weeks) increase of BMP-2, and declined close to normal at 8 weeks.

CONCLUSIONSRoughly focused ESWT may promote the expression of OPG and BMP-2 in the osteoporotic fracture area in rats. BMP-2 and OPG may act synergistically and may lead to a significant enhancement of bone formation and remodeling.

OBJECTIVE: To evaluate the effectiveness of lower energy flux density (EFD) extracorporeal shock wave therapy (ESWT) in the early stage of avascular necrosis (AVN) of the femoral head. METHODS: Nineteen patients and 30 hips were enrolled. All subjects received 4 weekly sessions of ESWT, at different energy levels; group A (n=15; 1,000 shocks/session, EFD per shock 0.12 mJ/mm²) and group B (n=15; 1,000 shocks/session, EFD per shock 0.32 mJ/mm²). We measured pain by using the visual analog scale (VAS), and disability by using the Harris hip score, Hip dysfunction and Osteoarthritis Outcome Score (HOOS), and the Western Ontario and McMaster University Osteoarthritis Index (WOMAC). To determine the effect of the lower EFD ESWT, we assessed the VAS, Harris hip score, HOOS, WOMAC of the subjects before and at 1, 3, and 6 months. RESULTS: In both groups, the VAS, Harris hip score, HOOS, and WOMAC scores improved over time (p<0.05). CONCLUSION: Lower EFD ESWT may be an effective method to improve the function and to relieve pain in the early stage of AVN.

OBJECTIVE: To evaluate the effects of extracorporeal shockwave therapy (ESWT) on pain, function, and ultrasonographic features of chronic stroke patients with knee osteoarthritis (OA). METHODS: A total of 18 chronic stroke patients (33 knee joints) with unilateral or bilateral knee OA (Kellgren-Lawrence grade ≥1) were enrolled in this study. The patients were randomly allocated to an experimental group receiving ESWT (n=9) or a control group receiving sham ESWT (n=9). For the ESWT group, patients received 1,000 pulses weekly for 3 weeks, totaling to an energy dose of 0.05 mJ/mm² on the proximal medial tibia of the affected knee. The assessments were performed before the treatment, immediately after the first treatment, and 1 week after the last treatment using the following: the visual analog scale (VAS) for pain; patient perception of the clinical severity of OA; the Korean version of Modified Barthel Index (ambulation and chair/bed transfer); the Functional Independence Measure scale (FIM; bed/chair/wheelchair transfer, toilet transfer, walking, and stairs); and ultrasonographic features (articular cartilage thickness, Doppler activity, and joint effusion height). RESULTS: The experimental group showed a significant improvement in VAS score (4.50±1.87 to 2.71±1.38) and patient perception of the clinical severity of OA (1.87±0.83 to 2.75±0.46). The bed/chair/wheelchair transfer components of the FIM score also improved significantly (4.12±1.55 to 4.62±1.30). In terms of the ultrasonographic features, increased Doppler activity was observed in the medial knee in the experimental group immediately following ESWT. CONCLUSION: It is suggested that ESWT may reduce pain and improve function in chronic stroke patients with OA, and may increase vascular activity at the target site.
