Validez actual de la litotricia extracorpórea como tratamiento de primera línea de la litiasis / Is extracorporeal lithotripsy a first-line treatment for urinary stones today?

Objetivo Evaluar la eficacia y complicaciones de la litotricia extracorpórea por ondas de choque (LEOCh) como tratamiento de primera línea de la litiasis renal y ureteral. Métodos Estudio observacional retrospectivo de todos los pacientes tratados con litotricia en un centro de tercer nivel entre enero de 2014 y enero de 2021. Se recogieron las características de los pacientes, de la litiasis, y las complicaciones y resultados de la LEOCh. Se realizó una regresión logística multivariante de los factores asociados a la reducción del tamaño litiásico. También se llevó a cabo un análisis estadístico de los factores asociados a la necesidad de tratamiento adicional tras la LEOCh y de los factores asociados a las complicaciones. Resultados Se incluyeron 1.727 pacientes. El tamaño litiásico medio fue de 9,5 mm. En 1.540 (89,4%) pacientes se observó la reducción del tamaño litiásico. En el análisis multivariante, el tamaño (OR=1,13; p=0,00), la localización de la litiasis en el uréter (OR=1,15; p=0,052) y el número de ondas (p=0,002; OR=1,00) utilizadas en la LEOCh son los factores asociados a la reducción del tamaño litiásico. Un total de 665 pacientes (38,5%) precisaron tratamiento adicional tras la litotricia. Los factores asociados a la necesidad de retratamiento fueron el tamaño litiásico (OR=1.131; p=0,000), el número de ondas (OR=1.000; p=0,000) y la energía administrada (OR=1.005; p=0,000). En 153 pacientes (8,8%) se produjeron complicaciones tras la LEOCh. Se encontró una asociación estadísticamente significativa entre el tamaño de la litiasis (p=0,024; OR=1.054) y la derivación urinaria previa (p=0,004; OR=0,571). Conclusión La litotricia sigue siendo eficaz como tratamiento de primera línea para la litiasis reno-ureteral, con un bajo porcentaje de complicaciones. (AU)

Objective To evaluate the efficacy and complications of extracorporeal lithotripsy (SWL) as a first-line treatment for renal and ureteral stones. Methods Retrospective and observational study of all the patients treated with lithotripsy in a third level center between January 2014 and January 2021; characteristics of the patients, the stones, complications and results of SWL is recollected. Multivariate logistic regression of the factors associated with stone size reduction was performed. A statistical analysis of the factors associated with additional treatment after SWL and factors associated with complications is also executed. Results 1727 patients are included. Stone mean size was 9,5 mm. 1540 (89.4%) patients presented reduction in stone size. In multivariate analysis, stone size (OR=1.13; P=0.00), ureteral location of the lithiasis (OR=1.15; P=0.052) and number of waves (P=0.002; OR=1.00) used in SWL are the factors associated with reduction of stone size. Additional treatment after lithotripsy was needed in 665 patients (38.5%). The factors associated with the need for retreatment were stone size (OR=1.131; P=0.000), number of waves (OR=1.000; P=0.000), energy (OR=1.005; P=0.000). 153 patients (8.8%) suffered complications after SWL. A statistically significant association was found between the size of the lithiasis (P=0.024, OR=1.054) and the previous urinary diversion (P=0.004, OR=0.571). Conclusion Lithotripsy remains an effective treatment as the first line of therapy for reno-ureteral lithiasis with a low percentage of complications. (AU)

¿Cómo calcular el volumen litiásico y cuál es su aplicación quirúrgica? / How to estimate stone volume and its use in stone surgery: A comprehensive review?

Objetivo Las guías actuales para el tratamiento intervencionista sugieren el diámetro acumulativo de la litiasis (DAL) como factor decisivo en la elección del tratamiento quirúrgico óptimo (ureteroscopia [URS], litotricia extracorpórea por ondas de choque [LEOCh] y nefrolitotomía percutánea [NLPC]). El volumen litiásico (VL) se ha introducido recientemente para obtener una estimación más precisa de la carga litiásica. El objetivo de esta revisión es resumir los métodos disponibles para calcular el VL y su aplicación quirúrgica. Material y métodos En diciembre de 2022 se realizó una revisión sistemática de la literatura mediante búsquedas en las bases de datos Embase, Cochrane y Pubmed. Los artículos se consideraron elegibles si describían la medición del VL o la tasa libre de litiasis (TLL) tras diferentes modalidades de tratamiento (LEOCh, URS, NLPC) o la expulsión espontánea, basándose en la medición del VL. Dos revisores evaluaron de forma independiente la elegibilidad y la calidad de los artículos y realizaron la extracción de datos. Resultados En total se incluyeron 28 estudios. Todos los estudios utilizaron diferentes técnicas para calcular el VL. La medición automática del volumen pareció ser más precisa que la estimación del volumen. Los estudios in vitro mostraron que la medición automática del volumen se ajustaba más al volumen real de la litiasis, con una menor variabilidad interobservador. A diferencia de la NLPC y la LEOCh, en la URS se observó que el VL era un mejor predictor de mejor la TLL que el diámetro litiásico mayor o el diámetro acumulativo en litiasis >20mm. Conclusiones Calcular el VL —de forma manual o automática— es factible, y probablemente se ajuste más a la carga litiásica real. Aunque en el caso de las litiasis grandes tratadas mediante cirugía intrarrenal retrógrada el VL parece predecir mejor la TLL, la superioridad del VL en todas las cargas litiásicas y para todos los tipos de tratamiento está aún por demostrar. ...

Objective Current interventional guidelines refer to the cumulative stone diameter to choose the appropriate surgical modality (ureteroscopy (URS), extracorporeal shockwave lithotripsy (ESWL) and percutaneous nephrolithotomy (PCNL)). The stone volume (SV) has been introduced recently, to better estimate the stone burden. This review aimed to summarize the available methods to evaluate the SV and its use in urolithiasis treatment. Material and methods A comprehensive review of the literature was performed in December 2022 by searching Embase, Cochrane and Pubmed databases. Articles were considered eligible if they described SV measurement or the stone free rate after different treatment modalities (SWL, URS, PCNL) or spontaneous passage, based on SV measurement. Two reviewers independently assessed the eligibility and the quality of the articles and performed the data extraction. Results In total, 28 studies were included. All studies used different measurement techniques for stone volume. The automated volume measurement appeared to be more precise than the calculated volume. In vitro studies showed that the automated volume measurement was closer to actual stone volume, with a lower inter-observer variability. Regarding URS, stone volume was found to be more predictive of stone free rates as compared to maximum stone diameter or cumulative diameter for stones >20mm. This was not the case for PCNL and SWL. Conclusions Stone volume estimation is feasible, manually or automatically and is likely a better representation of the actual stone burden. While for larger stones treated by retrograde intrarenal surgery, stone volume appears to be a better predictor of SFR, the superiority of stone volume throughout all stone burdens and for all stone treatments, remains to be proven. Automated volume acquisition is more precise and reproducible than calculated volume. (AU)

Combinação de terapia por ondas de choque extracorpórea e agulhamento seco no tratamento de lombalgia crônica incapacitante: um relato de caso / Combination of extracorporeal shockwave therapy and dry needling as treatment of disabling chronic low back pain: a case report

Paciente do sexo masculino, 55 anos, apresentava antecedente clínico de radiculopatia lombar abordado cirurgicamente (discectomia e artrodese L5-S1) em dezembro de 2021, com resolução completa da dor associada. Iniciou com quadro de dor pós-operatória de características distintas. A primeira sessão de tratamento iniciou-se com terapia por ondas de choque extracorpóreas focal direcionada ao quadrado lombar, glúteo médio, glúteo mínimo e região peritrocantérica à direita. Posteriormente, associou-se agulhamento seco em pontos-gatilho presentes nesses mesmos 3 músculos e também no ligamento sacrotuberal direito, junto à inserção do glúteo máximo direito. Numa reavaliação uma semana depois, o paciente referiu uma redução de 70% da intensidade da dor inicial. O mesmo tratamento foi repetido, com resolução completa dos sintomas no final da sessão. Três meses depois, o doente manteve o controle álgico e recuperou totalmente a sua funcionalidade e qualidade de vida anteriores. Neste caso de limitação funcional a longo prazo devido a dor lombar crônica, a combinação da terapia por ondas de choque extracorporais e do agulhamento seco resultou num método eficaz e rápido para obter o alívio da dor e restaurar a funcionalidade anterior. No entanto, são necessários mais estudos para investigar o impacto desta combinação de terapias no controle da dor e na perda de funcionalidade devido à dor lombar crônica.

Male patient, 55 years old, had a clinical background of lumbar radiculopathy and a surgical approach (L5-S1 discectomy and arthrodesis) in December of 2021, with complete resolution of associated pain. One year later, the patient seeks medical treatment, referring a new, different pattern of low back pain, which initiated post-surgery. The first treatment session began with focused extracorporeal shockwave therapy directed at the right quadratus lumborum, gluteus medius, gluteus minimus and peritrochanteric region. Afterwards, dry needling was associated in trigger-points present in those same 3 muscles and also in the right sacrotuberal ligament, close to the insertion of the right gluteus maximus. In a reevaluation one week later, the patient reported a reduction of 70% of initial pain intensity. The same treatment was repeated, with complete resolution of symptoms at the end of the session. Three months later, the patient-maintained symptom control and fully recovered his previous functionality and quality of life. In this case of long-term functional limitation due to chronic low back pain, the combination of extracorporeal shock wave therapy and dry needling resulted in an effective and quick method to achieve pain relief and restore previous functionality. However, more studies are needed to investigate the impact of this combination of therapies in pain management and functionality loss due to chronic low back pain.

Litotricia extracorpórea por ondas de choque (LEOCh) Para litiasis de grupo calicial inferior: ¿cómo predecir el éxito del tratamiento? / Extracorporeal shock wave lithotripsy for lower calyx stones: Predicting treatment success

Introducción El uso de la litotricia extracorpórea por ondas de choque (LEOCh) en litiasis de grupo calicial inferior (GCI) se asocia con una alta tasa de fragmentos residuales. Nuestro objetivo es analizar la efectividad y complicaciones del tratamiento con LEOCh en litiasis de GCI. Métodos Revisión retrospectiva de pacientes con litiasis en GCI tratadas con LEOCh entre enero 2014 y diciembre del 2020. Se determina anatomía favorable del GCI mediante longitud infundibular, ancho infundibular y ángulo infundibulopélvico. Se considera fracaso de LEOCh la presencia de fragmentos >3mm en radiografía simple, TC o ecografía a los 3 meses del procedimiento. Análisis de complicaciones, procedimientos auxiliares y factores de riesgo asociados con hematoma perirrenal. Análisis estadístico mediante software SPSS. Resultados En total, 512 pacientes con litiasis en GCI fueron tratados con LEOCh. El 80,3% de los pacientes tenía anatomía GCI favorable. La tasa libre de litiasis (TLL) fue 70,5%. Las principales complicaciones fueron: calle litiásica (5 pacientes) e infección del tracto urinario (3 casos). Se describen 10 hematomas perirrenales (2%). La toma de antiagregantes mostró asociación estadística con el riesgo de hematoma perirrenal (p=0,004). Mediante regresión logística binaria se demuestra asociación entre anatomía desfavorable del GCI (p=0,000), tamaño de litiasis (p=0,001), número de ondas de choque (p=0,003), energía aplicada (p=0,038) y necesidad de tratamiento adicional tras LEOCh. Conclusiones El tratamiento con LEOCh puede ser considerado de primera elección en litiasis de GCI. El tamaño de la litiasis, anatomía calicial desfavorable, número de ondas de choque y energía utilizadas pueden predecir la necesidad de retratamiento. (AU)

Introduction The use of extracorporeal shock wave lithotripsy (ESWL) for lower calyx stones is associated with a high rate of residual fragments. Our aim is to analyse the effectiveness and complications of ESWL for lower calyx stones. Methods Retrospective review of patients with lower renal calyx stones treated with ESWL between January-2014 and December-2020. Measurement of infundibular length, infundibular width and infundibulopelvic angle in lower renal pole to determine favourable anatomy. ESWL failure: fragments >3mm detected in plain abdominal film, CT scan and/or renal ultrasound 3 months after treatment. Complications after ESWL, auxiliary procedures along with risk factors associated with perirenal haematoma were analysed. SPSS statistical software was used. Results 512 patients with lower calyx stones were treated with ESWL. 80.3% of patients had a favourable anatomy. Overall stone-free rate was 70.5%. Regarding main complications after ESWL, stainstrasse was described in 5 patients and urinary tract infection in 3 patients. 10 perirenal haematomas (2%) were reported. Statistical association was found between antiplatelet treatment and the risk of perirenal haematoma (p=0.004). Logistic binary regression proved the association between unfavourable anatomy of the lower renal pole (p=0.000), size of the stone (p=0.001), number of shock waves (p=0.003), energy applied (p=0.038) and the need for additional treatment after ESWL. Conclusions ESWL can still be considered as the initial treatment option for lower renal pole stones. The size of the stone, an unfavourable anatomy of the lower renal calyx, number of shock waves and energy applied can help predict the need for additional treatment. (AU)

Introducción y objetivos Comparar la eficacia del bloqueo del plano del erector espinal (BPEE) y el diclofenaco sódico intramuscular (IM) en términos del manejo del dolor y su impacto sobre el estado libre de cálculos en pacientes sometidos a litotricia extracorpórea de ondas de choque (LEOCh). Pacientes y materiales El estudio incluyó a pacientes sometidos a LEOCh por litiasis renal en nuestro centro. Los pacientes fueron asignados aleatoriamente a los grupos de BPEE (Grupo 1: n = 31) y de 75 mg de diclofenaco sódico IM (Grupo 2: n = 30). Se registraron los datos demográficos de los pacientes, el tiempo de fluoroscopia durante la LEOCh, el número de focalizaciones, el total de disparos administrados, el voltaje, las tasas libre de cálculos (TLC), el método de analgesia, el número de sesiones de LEOCh, la puntuación de la Escala Visual Analógica (EVA) la localización de los cálculos, el tamaño máximo de los cálculos, el volumen de los cálculos y las unidades Hounsfield (UH). Resultados Un total de 61 pacientes fueron incluidos en el estudio. No hubo diferencias estadísticamente significativas entre los dos grupos en cuanto al tamaño, el volumen y la densidad de los cálculos, la duración de la LEOCh, el total de disparos administradas, el voltaje, el índice de masa corporal (IMC), el estado libre de cálculos y la localización de los cálculos. El tiempo de fluoroscopia y el número de veces que fue necesario focalizar el cálculo fueron significativamente inferiores en el grupo 1 con respecto al grupo 2 (p:0,002, p:0,021, respectivamente). La puntuación EVA fue significativamente inferior en el grupo 1 en comparación con el grupo 2 (p<0,001). Conclusiones Observamos que la puntuación EVA del grupo BPEE era menor que la del grupo de diclofenaco sódico IM y, aunque no de manera estadísticamente significativa, conseguimos una tasa libre de cálculos más alta en la primera sesión en el grupo BPEE. ...

Introduction and Objectives To compare the efficacy of erector spinae plane block (ESPB) and intramuscular (i.m.) diclofenac sodium in regard to pain management and impact on stone-free status in patients undergoing SWL. Patients or Materials The study included patients who underwent SWL for kidney stones in our institution. The patients were randomly assigned to the ESPB (Group 1: n = 31) and i.m. 75 mg diclofenac sodium (Group 2: n = 30) groups. The demographic data of the patients, fluoroscopy time during SWL, number of need of targeting, total shocks given, voltage, stone free rates (SFR), analgesy method, number of SWL sessions, VAS score, stone location, maximum stone size, stone volume and Hounsfield unit (HU) were also recorded. Results A total of 61 patients were included the study. There was no statistically significant difference between the two groups according to stone size, volume and density, SWL duration, total shocks given, voltage, BMI, stone-free status and stone location. Fluoroscopy time and number of need for stone targeting were significantly lower in group 1 than group 2 (p:0.002, p:0.021, respectively). The VAS score was significantly lower for group 1 compared to group 2 (p<0.001). Conclusions We observed that the VAS score was lower in the ESPB group compared to i.m. diclofenac sodium group and although it was not statistically significant, we achieved a higher rate of stone-free status in the first session in ESPB group. Most importantly, the patients in the ESPB group were exposed to less fluoroscopy and radiation. (AU)

Associação de estimulação por ondas de choque a toxina botulínica e baclofeno durante a reabilitação de paciente com lesão medular e trauma cranioencefálico: relato de caso / Association of extracorporeal shockwave stimulation to botulinum toxin and baclofen during an in-patient rehabilitation in spinal cord injury and traumatic brain injury: case report

Recentemente, a terapia por ondas de choque extracorpóreas (TOCE) mostraram-se ser uma promissora tecnologia não invasiva para neuromodulação e recuperação funcional devido a melhora em brotamento neuronal, neuroproteção, controle de neuroplasticidade e reorganização neuronal, além de atuar em fatores de neurogênese. Objetivo: Descrever um caso que usa TOCE como um adjuvante na reabilitação de trauma medular. Relato de caso: LPS, 25 anos, estudante de medicina, sofreu uma queda de altura indeterminada com fratura de C5 e lesão medular associada a trauma cranioencefálico. Na fase aguda, ele se recuperou adequadamente, tendo sido submetido a descompressão e fixação de coluna e hospitalizado por 5 meses devido a disautonomias e infecções urinárias. Após esse período, ele iniciou um programa de reabilitação intensiva para tetraplegia espástica com classificação inicial segundo o ASIA (American Spinal Injury Association) nível C5 motor e C6 sensório. O tratamento incluiu 10 sessões de TOCE, realizadas com Duolith SD1 (Storz Medical, Suíça) com uma densidade de energia de 0,25mJ/mm², 5 cm e 3 cm de profundidade de foco, 2000 pulsos aplicados na linha média de coluna níveis C5 a T1 e 2000 pulsos a 5 cm de profundidade aplicados em região plantar bilateral. Bloqueio com toxina botulínica e fenol foram realizados com resposta parcial apesar da dose otimizada de baclofeno.

Recently, extracorporeal shockwaves (ESWT) have shown as a promising non-invasive technology for neuromodulation and functional recovery, due to improving neuronal budding, neuroprotection, control of neuroplasticity and neuronal reorganization, in addition to acting on neurogenesis factors. Objective: To describe a case that uses ESWT as an adjuvant to the rehabilitation of spinal cord trauma. Case Report: LPS, 25 years old, medical student, suffered a fall from an undetermined height with C5 fracture and spinal cord injury, associated with a cranioencephalic trauma. In the acute phase, he was rescued properly, performed decompression and spinal cord fixation and remained hospitalized for 5 months due to dysautonomia and urinary infections. After this period, he started an intensive in-patient rehabilitation program for spastic tetraplegia with initial classification according to ASIA C5 (motor) and C6 (sensory). The treatment included 10 sessions of ESWT, made with Duolith SD1 (Storz Medical, Switzerland) with an Energy flux density 0,25 mJ/mm2, at 5cm and 3cm depth focus, 2000 pulses each over the spinal cord at the midline of levels from C5 to T1, and 2000 pulses at 5cm depth focus applied at plantar region bilaterally.

Extracorporeal shock wave lithotripsy for lower calyx stones: predicting treatment success.

INTRODUCTION: The use of extracorporeal shock wave lithotripsy (ESWL) for lower calyx stones is associated with a high rate of residual fragments. Our aim is to analyse the effectiveness and complications of ESWL for lower calyx stones. METHODS: Retrospective review of patients with lower renal calyx stones treated with ESWL between January-2014 and December-2020. Measurement of infundibular length, infundibular width and infundibulopelvic angle in lower renal pole to determine favourable anatomy. ESWL failure: fragments >3 mm detected in plain abdominal film, CT scan and/or renal ultrasound 3 months after treatment. Complications after ESWL, auxiliary procedures along with risk factors associated with perirenal haematoma were analysed. SPSS statistical software was used. RESULTS: 512 patients with lower calyx stones were treated with ESWL. 80.3% of patients had a favourable anatomy. Overall stone-free rate was 70.5%. Regarding main complications after ESWL, stainstrasse was described in 5 patients and urinary tract infection in 3 patients. 10 perirenal haematomas (2%) were reported. Statistical association was found between antiplatelet treatment and the risk of perirenal haematoma (p = 0.004). Logistic binary regression proved the association between unfavourable anatomy of the lower renal pole (p = 0.000), size of the stone (p = 0.001), number of shock waves (p = 0.003), energy applied (p = 0.038) and the need for additional treatment after ESWL. CONCLUSIONS: ESWL can still be considered as the initial treatment option for lower renal pole stones. The size of the stone, an unfavourable anatomy of the lower renal calyx, number of shock waves and energy applied can help predict the need for additional treatment.

INTRODUCTION AND OBJECTIVES: To compare the efficacy of erector spinae plane block (ESPB) and intramuscular (i.m.) diclofenac sodium in regard to pain management and impact on stone-free status in patients undergoing SWL. PATIENTS AND MATERIALS: The study included patients who underwent SWL for kidney stones in our institution. The patients were randomly assigned to the ESPB (Group 1: n = 31) and i.m. 75 mg diclofenac sodium (Group 2: n = 30) groups. The demographic data of the patients, fluoroscopy time during SWL, number of need of targeting, total shocks given, voltage, stone free rates (SFR), analgesy method, number of SWL sessions, VAS score, stone location, maximum stone size, stone volume and Hounsfield unit (HU) were also recorded. RESULTS: A total of 61 patients were included the study. There was no statistically significant difference between the two groups according to stone size, volume and density, SWL duration, total shocks given, voltage, BMI, stone-free status and stone location. Fluoroscopy time and number of need for stone targeting were significantly lower in group 1 than group 2 (p = 0.002, p = 0.021, respectively). The VAS score was significantly lower for group 1 compared to group 2 (p < 0.001). CONCLUSIONS: We observed that the VAS score was lower in the ESPB group compared to i.m. diclofenac sodium group and although it was not statistically significant, we achieved a higher rate of stone-free status in the first session in ESPB group. Most importantly, the patients in the ESPB group were exposed to less fluoroscopy and radiation.

Estimulação cerebral por pulsos sonoros de baixa frequência como coadjuvante nas alterações das funções corticais superiores / Non-invasive brain stimulation by low-frequency sound pulses as an adjunct to changes in higher cortical functions

Não há dúvidas sobre os prejuízos na vida humana, extensivos à família e sociedade como um todo, abrangendo todos os aspectos funcionais das pessoas envolvidas, além do indivíduo, originados dos traumatismos cranioencefálico, agudos e crônicos, externos ou internos: acidentes, atropelamentos, quedas, crimes, acidente vascular cerebral, doenças com neurodegeneração progressiva, resultando em estados demenciais. Ao longo de meio século, houve a introdução contínua de medicamentos, com resultados usualmente contraditórios e frustrantes, exigindo novas tentativas com outras classes farmacológicas. No todo, a limitação se faz sentir na impossibilidade de reversão ou mesmo de mera estabilização dos danos neurológicos, e inocuidade em termos de estimulação da neuroplasticidade. Uma exceção parece ser uma nova abordagem: a estimulação cerebral profunda por pulsos sonoros de baixa frequência (Transcranial Pulse Stimulation, ou TPS). Ainda pouco conhecida, a não ser em alguns centros de tratamento, tem se mostrado ser um acréscimo válido, por complementar os programas multidisciplinares de reabilitação

There is no doubt about the damage to human life, also extended to family and society as a whole, regarding all the functional aspects of those involved, not only the patient itself, which originates from traumatic brain injury, acute or chronic, for external or internal reasons, such as accidents, run overs, falls, crimes, stroke, progressive neurodegenerative diseases that result in dementia states. Over half a century, drugs have been continuously introduced, however their results have constantly been contradictory and frustrating, requiring new attempts with other pharmacological classes. Overall, the limitation is felt in the impossibility of reversing or even merely stabilizing the neurological damage and inefficacy regarding neuroplasticity stimulation. One exception seems to be a new approach, the non-invasive brain stimulation by low-frequency sound pulses (Transcranial Pulse Stimulation, or TPS). Except for some treatment centers, TPS is still unknown, however it has shown to be a valid adjunct in multidisciplinary rehabilitation programs

Experiencia en el tratamiento de la enfermedad de Dupuytren con ondas de choque radiales: estudio de caso / Experience in the treatment of Dupuytren's disease with radial extracorporeal shockwave therapy: A case report

Introducción y objetivos La enfermedad de Dupuytren (ED) es un trastorno proliferativo benigno que afecta a la aponeurosis palmar y dedos en la mano. Los tratamientos propuestos son en su mayoría invasivos y presentan recurrencias. Se ha postulado la utilización de ondas de choque para el manejo de esta enfermedad dado su bajo costo, además de ser una técnica no invasiva. El objetivo de este trabajo es describir una experiencia terapéutica en el manejo de la ED utilizando ondas de choque radiales (OCr). Material y métod Mujer de 72 años, presenta tejido fibroso retráctil en la palma de ambas manos asociado al dedo meñique, manifestando dolor a la presión y limitación severa de la movilidad en extensión. Se evaluó la intensidad de dolor al reposo y al movimiento, umbral de dolor a la presión, movilidad, fuerza prensil, discapacidad y severidad de la ED. Se realizaron 6 sesiones de OCr distribuidas en 4 semanas, utilizando 2000 pulsos a 14Hz y 1,4bar, para luego seguir con 2000 pulsos a 6Hz y 3,4bar. Resultados: Se evidenciaron mínimas mejorías en todas las variables evaluadas. Estas no generaron una diferencia mínima clínicamente importante. Conclusión Basado en esta experiencia, las OCr no produjeron un cambio clínico relevante en el tratamiento de la ED en estadio avanzado. Es necesario profundizar en la eficacia de esta técnica considerando el tipo de ondas de choque que se utiliza, así como una estadificación variada que permita evidenciar los efectos según la severidad de la ED (AU)

Background and objectives Dupuytren's disease (DD) is a benign proliferative disorder that affects the palmar aponeurosis and fingers. Current treatments are mostly invasive and have recurrences. Extracorporeal shockwave therapy has been proposed for the management of this disease, given its low cost, in addition to being a non-invasive technique. The aim of this study is present a therapeutic experience in DD using radial extracorporeal shockwave therapy (rESWT). Material and method A 72-year-old woman presented in both hands a band of palmar fibrous tissue associated with the little finger, manifesting pain on pressure and severe limitation of extension. Pain intensity at rest and movement, pressure pain threshold, mobility, grip strength, disability, and severity of DD were evaluated. Six sessions of rESWT were performed distributed over 4 weeks using 2000 pulses at 14Hz and 1.4bar followed by 2000 pulses at 6Hz and 3.4bar. Results Minimal improvements were evidenced in all the variables evaluated. The effect of the intervention was not sufficient to generate a minimal clinically important difference. Conclusion Based on this experience, rESWT did not generate a relevant clinical change in the treatment of advanced-stage DD. It is necessary to inquire into the efficacy of this technique considering the type of extracorporeal shockwave used, as well as a varied staging that allows evidence the effects of radial shockwaves according to the severity of disease (AU)

¿Son suficientes los nomogramas actuales para predecir los resultados de la litotricia por ondas de choque? / Are the current nomograms sufficient to predict shockwave lithotripsy outcomes?

Introducción y objetivos: Investigar los factores que afectan los resultados del tratamiento con LEOCH, validar tres nomogramas actuales (Kim JK, Triple D y S3HoCKwave) y comparar la capacidad predictiva de los nomogramas para los resultados de la LEOCH en los cálculos del tracto urinario superior.Pacientes y métodosSe revisaron retrospectivamente las historias clínicas de los pacientes con cálculos renales y ureterales proximales tratados con LEOCH entre marzo de 2013 y octubre de 2020. Se analizaron los factores que afectan al éxito de LEOCH con un análisis de regresión logística multivariante y se compararon los tres sistemas de puntuación con el área bajo la curva (AUC).ResultadosNuestro estudio incluyó un total de 580 pacientes. La tasa global de eliminación de cálculos fue del 61% y 144/580 pacientes (24,8%) estaban libres de cálculos tras una sesión. En el análisis de regresión logística multivariante, la ubicación del cálculo en el cáliz superior (OR: 2,988; IC 95%: 1,350-6,612; p=0,007), en el cáliz medio (OR: 3,036; IC 95%: 1,472-6,258; p=0,003) y en el cáliz inferior (OR: 2,131; IC 95%: 1,182-3,839; p=0,012), así como el número de cálculos (OR: 1,663; IC 95%: 1,140-2,425; p=0,008), el diámetro máximo del cálculo (OR: 1,156; IC 95%: 1,098-1,217; p<0,001) y el valor máximo de unidades Hounsfield (OR: 1,001; IC 95%: 1,001-1,002; p<0,001) fueron factores de riesgo independientes del fracaso de LEOCH. Las AUC de las puntuaciones Kim JK, Triple D y S2HoCKwave para predecir el éxito de la LEOCH fueron de 0,678, 0,548 y 0,626, respectivamente (AU)

Introduction and objectives: To investigate factors affecting SWL outcomes, validate three current nomograms (Kim JK, Triple D and S3HoCKwave) and compare the predictive ability of the nomograms for SWL outcomes in upper urinary tract stones.Patients and methodsMedical records of patients with renal and proximal ureteral stones treated with SWL between March 2013 and October 2020 were retrospectively reviewed. Factors affecting SWL success were analyzed with multivariate logistic regression analysis and the three predictive scoring systems compared with the area under the curve (AUC).ResultsA total of 580 patients were included in our study. The overall stone free rate was 61% and 144/580 patients (24.8%) were stone free after one session. In multivariate logistic regression analysis, stone location at upper calyx (OR:2.988; 95%Cl: 1.350–6.612; p=0.007), middle calyx (OR:3.036; 95%Cl: 1.472–6.258; p=0.003), and lower calyx (OR:2.131; 95%Cl: 1.182–3.839; p=0.012), as well as number of stones (OR:1.663; 95%Cl: 1.140–2.425; p=0.008), maximum diameter of stone (OR:1.156; 95%Cl: 1.098–1.217; p<0.001) and maximum Hounsfield Unit (OR:1.001; 95%Cl: 1.001–1.002; p<0.001) were independent risk factors of SWL failure. The AUCs of the Kim JK, Triple D and S2HoCKwave scores for predicting SWL success were 0.678, 0.548, and 0.626 respectively.ConclusionsStone location, number, maximal diameter, and maximum HU were independent predictive factors for SWL outcome in the treatment of upper urinary tract stones. Current nomograms, Kim JK nomogram, Triple D score and S3HoCKwave score can predict treatment success after SWL, but all of them have poor discrimination according to AUC analysis. (AU)

Calcificación del ligamento colateral medial de la rodilla: manejo rehabilitador con ondas de choque más iontoforesis de una entidad poco frecuente. Caso clínico y revisión / Calcification of the medial collateral ligament of the knee: Rehabilitative management with radial electro shock wave therapy plus iontophoresis of a rare entity. Clinical case and review

El ligamento colateral medial (LCM) de la rodilla es una estructura ligamentosa muy frecuentemente lesionada. La calcificación del LCM es muy infrecuente, benigna, relacionada con desórdenes metabólicos y es consecuencia del depósito de hidroxiapatita de calcio en la región periarticular. El cuadro clínico, histológico y radiológico de la tendinitis calcificante está definido y la etiología es multifactorial. El tratamiento es inicialmente conservador, y si fracasara, intervencionista, siendo la cirugía el último escalón terapéutico. Existen muy pocos reportes en la literatura, estando publicados apenas 10 casos/series de casos. Es importante diferenciarlo del signo y/o síndrome de Pellegrini-Stieda, donde el antecedente traumático es fundamental para diagnosticarlo.El caso clínico es el de una mujer de 64 años en quien presentamos el tratamiento de la calcificación del LCM mediante ondas de choque más iontoforesis, reportamos la efectividad del tratamiento en el manejo del dolor y la calcificación y realizamos una somera revisión sobre el tema.(AU)

The medial collateral ligament (MCL) of the knee is a commonly injured ligament structure. Calcification of the MCL is very infrequent, benign, related to metabolic disorders and is a consequence of the deposition of calcium hydroxyapatite in the periarticular region. The clinical, histological and radiological picture of calcific tendonitis is defined and the etiology is multifactorial. Treatment is initially conservative and if it fails, interventionist; surgery being the last therapeutic step. There are very few reports in the literature, with only 10 cases/case series published. It is important to differentiate it from the Pellegrini–Stieda sign and/or syndrome, where the traumatic history is essential to diagnose it.The clinical case is that of a 64-year-old woman in whom we present the treatment of calcification of the MCL using radial electro shock wave therapy plus iontophoresis, we report the effectiveness of the treatment in the management of pain and calcification, and we carry out a brief review on the subject.(AU)

Are the current nomograms sufficient to predict shockwave lithotripsy outcomes?

INTRODUCTION AND OBJECTIVES: To investigate factors affecting SWL outcomes, validate three current nomograms (Kim JK, Triple D and S3HoCKwave) and compare the predictive ability of the nomograms for SWL outcomes in upper urinary tract stones. PATIENTS AND METHODS: Medical records of patients with renal and proximal ureteral stones treated with SWL between March 2013 and October 2020 were retrospectively reviewed. Factors affecting SWL success were analyzed with multivariate logistic regression analysis and the three predictive scoring systems compared with the area under the curve (AUC). RESULTS: A total of 580 patients were included in our study. The overall stone free rate was 61% and 144/580 patients (24.8%) were stone free after one session. In multivariate logistic regression analysis, stone location at upper calyx (OR:2.988; 95%Cl: 1.350-6.612; p = 0.007), middle calyx (OR:3.036; 95%Cl: 1.472-6.258; p = 0.003), and lower calyx (OR:2.131; 95%Cl: 1.182-3.839; p = 0.012), as well as number of stones (OR:1.663; 95%Cl: 1.140-2.425; p = 0.008), maximum diameter of stone (OR:1.156; 95%Cl: 1.098-1.217; p < 0.001) and maximum Hounsfield Unit (OR:1.001; 95%Cl: 1.001-1.002; p < 0.001) were independent risk factors of SWL failure. The AUCs of the Kim JK, Triple D and S2HoCKwave scores for predicting SWL success were 0.678, 0.548, and 0.626 respectively. CONCLUSIONS: Stone location, number, maximal diameter, and maximum HU were independent predictive factors for SWL outcome in the treatment of upper urinary tract stones. Current nomograms, "Kim JK nomogram", "Triple D score" and "S3HoCKwave score" can predict treatment success after SWL, but all of them have poor discrimination according to AUC analysis.

Influencia de la densidad de energía de ondas de choque focalizadas en el tratamiento de la fascitis plantar / Influence of energy density on the effectiveness of the treatment of plantar fasciitis with focused extracorporeal shock waves

Resumen La fascitis plantar (FP) es una patología frecuente e invalidante que puede tratarse con ondas de choque focalizadas. El objetivo principal del estudio fue valorar la eficacia del tratamiento con ondas de choque focalizadas en la FP según la densidad de energía utilizada. Se incluyeron 82 pacientes con diagnóstico clínico de FP que fueron asignados mediante muestreo aleatorio simple a dos grupos de tratamiento: densidad de energía media- alta (0,59mJ/mm2) y densidad de energía media-baja (0,27mJ/mm2). Se evaluaron el dolor y la funcionalidad, mediante las escalas EVA (Escala Visual Analógica) y AOFAS (American Orthopedic Foot and Ankle Society Ankle-Hindfoot Scale) respectivamente, al inicio del estudio (consulta base), y al primer, tercer y sexto mes tras el tratamiento. Por último, se evaluó el grado de satisfacción de los pacientes mediante la escala de Roles y Maudsley. Se compararon los resultados de las escalas en las revisiones posteriores al tratamiento, obteniéndose significación estadística para las variables principales del estudio (dolor y funcionalidad) en cada grupo de intervención. Aunque los niveles de dolor y la funcionalidad mejoraron en ambos grupos de estudio, se obtuvo una respuesta analgésica y funcional mayor y más precoz en el grupo tratado con densidad de energía media-alta.

Abstract Plantar fasciitis (FP) is a frequent and disabling condition that can be treated with focused extracorporeal shock waves. The main objective of this study was to assess the effectiveness of focused extracorporeal shockwave treatment in FP according to the energy density used. Eighty-two patients with a clinical diagnosis of FP were included and assigned, by simple random sampling, to two treatment groups: medium-high energy density (0.59mJ/mm2) and low-medium energy density (0.27mJ/mm2). Pain and functionality were assessed using the VAS (Visual Analogical Scale) and AOFAS (American Orthopedic Foot and Ankle Society Ankle-Hindfoot Scale) scales, respectively, at the start of the study (baseline consultation), and at the first, third and sixth month post-treatment. Finally, the degree of patient satisfaction was evaluated using the Roles and Maudsley score. The results of the scales in the post-treatment reviews were compared, and statistical significance was obtained for the main study variables (pain and functionality) in each intervention group. Although pain levels and functionality improved in both study groups after treatment, a greater and earlier analgesic and functional response was obtained for the medium-high energy density group.

Modelo novedoso basado en los parámetros de la tomografía para predecir el éxito de la litotricia por ondas de choque en los cálculos ureterales de diferentes localizaciones / A novel model using computed tomography parameters to predict shock wave lithotripsy success in ureteral stones at different locations

ObjetivoIncorporar los parámetros basados en la tomografía computarizada sin contraste (TCSC) a las características de los cálculos y de los pacientes comúnmente asociadas con el éxito de la litotricia por ondas de choque (LEOCH) para evaluar la efectividad de este nuevo modelo en la predicción del éxito de LEOCH en cálculos ureterales únicos situados en diferentes localizaciones.Materiales y métodosSe revisaron retrospectivamente los datos de los pacientes tratados con LEOCH por un único cálculo ureteral entre enero de 2017 y enero de 2019. Los parámetros basados en la TCSC se evaluaron junto con los parámetros demográficos de los pacientes y las características de los cálculos. Los parámetros basados en TCSC incluyeron la presencia o ausencia de hidronefrosis, trabeculación de la grasa perirrenal, edema periureteral, diámetro del uréter proximal, grosor de la pared ureteral (GPU) en el sitio del cálculo ureteral. Se utilizó el método de regresión logística para desarrollar un modelo predictivo útil. Posteriormente, se utilizó la curva ROC para determinar los puntos de corte, y se desarrolló un sistema de puntuación para la predicción del éxito de LEOCH.ResultadosLa tasa libre de cálculos fue del 77,1% (267/346) en toda la cohorte. El análisis univariante reveló que la edad, el volumen de los cálculos, la densidad, la trabeculación perirrenal, el diámetro del uréter proximal y el GPU se asociaron con el éxito de la LEOCH. En el análisis multivariante, la localización del cálculo ureteral proximal, el volumen del cálculo, la densidad y el GPU fueron predictores independientes del éxito de la LEOCH. La fórmula utilizada en el análisis de regresión logística fue: 1/[1+exp {-8,856+0,008(volumen del cálculo)+0,002 (densidad del cálculo)+0,673 (GPU)+1026 (cálculo ureteral proximal)}]. Las puntuaciones de 0, 1, 2, 3 y 4 se asociaron con un 97,8%, 83,4%, 60,8%, 33,2% y 11,1% de éxito, respectivamente, en el modelo de predicción basado en estos parámetros.

ObjectiveTo combine non-contrast computerized tomography (NCCT)-based parameters with stone and patient characteristics that are already known to affect shock wave lithotripsy (SWL) success and assess this novel model's effectiveness in predicting SWL success for single ureteral stones in different locations.Materials and methodsData of patients treated by SWL for a single ureteral stone between January 2017 and January 2019 were retrospectively reviewed. Demographic parameters of patients and stone characteristics were combined with NCCT-based parameters. NCCT-based parameters included the presence or absence of hydronephrosis, perinephric stranding, periureteral edema, diameter of the proximal ureter, ureteral wall thickness (UWT) at ureteral stone site. The logistic regression method was used for the development of a useful predictive model. Subsequently, the receiver operating curve was used to determine cut-off levels, and a scoring system was developed for prediction of SWL success.ResultsStone-free rate was 77,1% (267/346) in the entire cohort. Univariate analysis revealed that age, stone volume, density, perinephric stranding, diameter of proximal ureter, and UWT, were associated with SWL success. In multivariate analysis, proximal ureteral stone location, stone volume, density, and UWT were independent predictors of SWL success. The formula used during logistic regression analysis was: 1/[1+exp {-8.856+0.008(stone volume)+0.002 (stone density)+0.673 (UWT)+1026 (proximal ureteral stone)}]. The scores of 0, 1, 2, 3 and 4 were associated with 97,8%, 83,4%, 60,8%, 33,2% and 11,1% success rates, respectively, in the prediction model based on these parameters.ConclusionWe conclude that our model can facilitate decision-making for SWL treatment of ureteral stones in different locations (AU)
