Supra-inguinal fascia iliaca block in older-old patients for hip fractures: a retrospective study

Abstract Background: Pain management in hip fracture patients is of great importance for reducing postoperative morbidity and mortality. Multimodal techniques, including peripheral nerve blocks, are preferred for postoperative analgesia. Older-old hip fracture patients with high ASA scores are highly sensitive to the side effects of NSAIDs and opioids. Our aim was to investigate the effectiveness of the recently popularized Supra-Inguinal Fascia Iliaca Block (SIFIB) in this population. Methods: Forty-one ASA III-IV patients who underwent SIFIB + PCA (G-SIFIB) or PCA alone (Group Control: GC) after general anesthesia were evaluated retrospectively. In addition to 24-hour opioid consumption, Visual Analog Scale (VAS) scores, opioid-related side effects, block-related complications, and length of hospital stay were compared. Results: Twenty-two patients in G-SIFIB and 19 patients in GC were evaluated. The postoperative 24-hour opioid consumption was lower in G-SIFIB than in GC (p < 0.001). There was a statistically significant reduction in VAS scores at the postoperative 1st, 3rd, and 6th hours at rest (p < 0.001) and during movement (p < 0.001 for the 1st and 3rd hours, and p = 0.02 for the 6th hour) in G-SIFIB compared to GC. There was no difference in pain scores at the 12th and 24th hours postoperatively. While there was no difference between the groups in terms of other side effects, respiratory depression was significantly higher in GC than in G-SIFIB (p = 0.01). Conclusion: The SIFIB technique has a significant opioid-sparing effect and thus reduces opioid-related side effects in the first 24 hours after hip fracture surgery in older-old patients.

Pericapsular Nerve Group (PENG) block versus fascia iliaca compartment (FI) block for hip surgery: a systematic review and meta-analysis of randomized controlled trials

Abstract Background: This study compares Fascia Iliaca compartment (FI) block and Pericapsular Nerve Group (PENG) block for hip surgery. Methods: Pubmed, Embase and Cochrane were systematically searched in April 2022. Inclusion criteria were: Randomized Controlled Trials (RCTs); comparing PENG block versus FI block for hip surgery; patients over 18 years of age; and reporting outcomes immediately postoperative. We excluded studies with overlapped populations and without a head-to-head comparison of the PENG block vs. FI block. Mean-Difference (MD) with 95% Confidence Intervals (CI) were pooled. Trial Sequential Analyses (TSA) were performed to assess inconsistency. Quality assessment and risk of bias were performed according to Cochrane recommendations. Results: Eight RCTs comprising 384 patients were included, of whom 196 (51%) underwent PENG block. After hip surgery, PENG block reduced static pain score at 12h post-surgery (MD = 0.61 mm; 95% CI 1.12 to -0.09; p = 0.02) and cumulative postoperative oral morphine consumption in the first 24h (MD = -6.93 mg; 95% CI -13.60 to -0.25; p = 0.04) compared with the FI group. However, no differences were found between the two techniques regarding dynamic and static pain scores at 6 h or 24 h post-surgery, or in the time to the first analgesic rescue after surgery. Conclusion: The findings suggest that PENG block reduced opioid consumption in the first 24 h after surgery and reduced pain scores at rest at 12 h post-surgery. Further research is needed to fully understand the effects of the PENG block and its potential benefits compared to FI block.

Professor LI De-hua's experience in treating facial nerve injury after total parotidectomy with blade needle based on jingjin theory / 中国针灸

The paper summarizes the academic thought and clinical experience of professor LI De-hua in treatment of facial nerve injury after total parotidectomy with blade needle based on jingjin (muscle region of meridian, sinew/fascia) theory. This disease is located at muscle regions of hand-/foot-three yang meridians; and the sinew/fascia adhesion is its basic pathogenesis, manifested by "transversely-distributed collaterals" and "knotted tendons". In treatment, the knotted tendons are taken as the points. Using the relaxation technique of blade needle, the lesions of sinews/fascia are dissected and removed to release the stimulation or compression to the nerves and vessels so that the normal function of sinews/fascia can be restored.

Exploration of the thinking and methods in treatment of cancer pain with acupuncture and moxibustion on the base of the fascia theory / 中国针灸

There is a commonality between jingjin (muscle region of meridian) and the fascial network for coordinating the balance in the body. The occurrence and the progression of tumor may disrupt the overall coordination between the fascial network and jingjin directly or indirectly, thereby, the impairment of this coordination may result in cancer pain. Rooted on the theory of overall balance of the fascial network, and combined with understanding of pain in jingjin theory, professor HUANG Jin-chang emphasizes the importance of "relaxing the knot" in treatment of cancer pain. It is recommended to select the fascia reaction point as the target point, in accordance with the principle of balance adjustment and apply various acupuncture and moxibustion therapies, such as Fu's subcutaneous needling, small-needle scalpel therapy, fire needling, and moxibustion.

A decade's review for membrane anatomy: the setting,events in it, order formed by primary fascia and serous membrane / 中华胃肠外科杂志

The successful report of total mesorectal excision (TME)/complete mesocolic excision (CME) has encouraged people to apply this concept beyond colorectal surgery. However, the negative results of the JCOG1001 trial denied the effect of complete resection of the "mesogastrium" including the greater omentum on the oncological survival of gastric cancer patients. People even believe that the mesentery is unique in the intestine, because they have a vague understanding of the structure of the mesentery. The discovery of proximal segment of the dorsal mesogastrium (PSDM) proved that the greater omentum is not the mesogastrium, and further revised the structure (definition) of the mesentery and revealed its container characteristics, i.e. the mesentery is an envelope-like structure, which is formed by the primary fascia (and serosa) that enclose the tissue/organ/system and its feeding structures, leading to and suspended on the posterior wall of the body. Breakdown of this structure leads to the simultaneous reduction of surgical and oncological effects of surgery. People quickly realized the universality of this structure and causality which cannot be matched by the existing theories of organ anatomy and vascular anatomy, so a new theory and surgical map- membrane anatomy began to form, which led to radical surgery upgraded from histological en bloc resection to anatomic en bloc resection.

Application of membrane anatomy in hepatopancreatobiliary and splenic surgery / 中华外科杂志

Understanding of a variety of membranous structures throughout the body,such as the fascia,the serous membrane,is of great importance to surgeons. This is especially valuable in abdominal surgery.

Chinese expert consensus on definition and terminology of colon and rectum: mesentery, fascia, and space (2023 edition) / 中华胃肠外科杂志

Anatomy is the foundation of surgery. However, traditional anatomical concepts based on autopsy are no longer sufficient to guide the development of modern surgery. With the advancement of histology and embryology and application of high-resolution laparoscopic technology, surgical anatomy has gradually developed. Meanwhile, some important concepts and terms used to guide surgery have emerged, including: mesentery, fascia, and space. The confusing, controversial, and even inaccurate definitions and anatomical terms related to colorectal surgery seriously affect academic communication and the training of young surgeons. Therefore, the Chinese Society of Colorectal Surgeons, the Chinese Society of Colorectal Surgery, National Health Commission Capacity Building and Continuing Education Center, and China Sexology Association of Colorectal Functional Surgery organized colorectal surgeons to make consensus on the definition and terminology of mesentery, fascia, and space related to colon and rectum, to promote surgeons' understanding of modern anatomy related to colorectal surgery and promote academic communication.

Use of the serratus anterior fascia in immediate implant-based breast reconstruction

Using the serratus anterior fascia may be a safe and effective option to recreate the lateral breast profile during subpectoral breast reconstruction, with minimal functional impact on the donor site. However, the literature is scarce when it comes to studies on this fascia flap in implant-based reconstruction. This article aimed to review the use of the serratus anterior fascia in immediate implant-based breast reconstruction, searching the electronic databases PubMed, Embase, Lilacs, and SciELO. The search was carried out by combining the following keywords: 'breast reconstruction' and 'serratus anterior fascia'. In the Pubmed and Embase databases, the search yielded a total of 12 and 15 articles, respectively, of which seven were selected according to the scope of this article. We found no studies on serratus anterior fascia and breast reconstruction in the Lilacs and SciELO databases. All works have results favorable for the use of the serratus anterior fascia flap and agree that this technique can be considered in the algorithm for the coverage of the inferolateral portion during subpectoral breast reconstruction

The effect of the minimum effective volume for suprainguinal fascia iliaca block in fresh cadavers / El efecto del volumen efectivo mínimo para el bloqueo de la fascia ilíaca suprainguinal en cadáveres frescos

SUMMARY: The goal of ultrasound-guided suprainguinal fascia iliaca block (USG-SFIB) is anesthetic spread to three nerves, which are lateral femoral cutaneous nerve (LFCN), femoral nerve (FN), and obturator nerve (ON). The 90 % minimum effective volume (MEV90) for USG-SFIB is each result of studied showed the successful block and effect in various volume for block. So, Thus, the study purposes to demonstrate the efficiency of the effective volume (MEV90,62.5 ml) for USG-SFIB and confirm the staining of dye in connective tissue of nerve (nerve layer) that focused on the obturator nerve by histological examination in cadavers. The histological result showed the dye staining on the nerve layer of the ON in epineurium (100 %) and un-staining perineurium & endoneurium. Therefore, the minimal effective volume (MEV) is effective for USG-SFIB. Moreover, dye stain at the epineurium of stained obturator nerve only.

RESUMEN: El objetivo del bloqueo de la fascia ilíaca suprainguinal guiado por ecografía (USG-SFIB) es la propagación anestésica a tres nervios, cutáneo femoral lateral, femoral y obturador. El volumen efectivo mínimo del 90 % (MEV90) para USG-SFIB en cada uno de los resultados mostró el bloqueo exitoso y el efecto en varios volúmenes por bloqueo. Por lo tanto, el estudio tuvo como objetivo demostrar la eficiencia del volumen efectivo (MEV90,62.5 ml) para USG-SFIB y confirmar la tinción de tinte en el tejido conectivo del nervio, el cual se centró en el nervio obturador a través del examen histológico en cadáveres. El resultado histológico mostró tinción de colorante en el epineuro (100 %) del nervio obturador, sin embargo no hubo tinción del perineuro y endoneuro. Por lo tanto, el volumen efectivo mínimo (MEV) es efectivo para USG-SFIB.

Distribution of various volumes of methylene blue injection in suprainguinal fascia iliaca block under ultrasound guidance: a cadaveric study / Distribución de varios volúmenes de inyección de azul de metileno en el bloque suprainguinal de la fascia ilíaca bajo guía por ultrasonido: un estudio cadavérico

SUMMARY: The local anesthetic volume for a single-shot suprainguinal fascia iliaca block (SFIB) is a key factor of a block success because the courses of the three target nerves from the lumbar plexus (LP), the lateral femoral cutaneous nerve (LFCN), femoral nerve (FN), and obturator nerve (ON), at the inguinal area are isolated and within striking distance. Thus, this cadaveric study aims to demonstrate the distribution of dye staining on the LFCN, FN, ON, and LP following the ultrasound-guided SFIB using 15-50 ml of methylene blue. A total of 40 USG-SFIBs were performed on 20 fresh adult cadavers using 15, 20, 25, 30, 35, 40, 45, and 50 ml of methylene blue. After the injections, the pelvic and inguinal regions were dissected to directly visualize the dye stained on the LFCN, FN, ON, and LP. All FN and LFCN were stained heavily when the 15-50 ml of dye was injected. Higher volumes of dye (40-50 ml) spread more medially and stained on the ON and LP in 60 % of cases. To increase the possibility of dye spreading to all three target nerves and LP of the SFIB, a high volume (≥40 ml) of anesthetic is recommended. If only a blockade of the FN and LFCN is required, a low volume (15-25 ml) of anesthetic is sufficient.

RESUMEN: El volumen de anestésico local para un bloqueo de la fascia ilíaca suprainguinal (FISI) de una sola inyección es un factor clave para el éxito del bloqueo, debido a que los cursos de los tres nervios objetivo del plexo lumbar (PL), el nervio cutáneo femoral lateral (NCFL), femoral (NF) y el nervio obturador (NO), en el área inguinal están aislados y dentro de la distancia de abordaje. Por lo tanto, este estudio cadavérico tiene como objetivo demostrar la distribución de la tinción de tinte en NCFL, NF, NO y PL siguiendo el FISI guiado por ultrasonido usando 15-50 ml de azul de metileno. Se realizaron un total de 40 USG-FISI en 20 cadáveres adultos frescos utilizando 15, 20, 25, 30, 35, 40, 45 y 50 ml de azul de metileno. Después de las inyecciones, se disecaron las regiones pélvica e inguinal para visualizar directamente el tinte teñido en NCFL, NF, NO y PL. Todos los NF y NCFL se tiñeron intensamente cuando se inyectaron los 15- 50 ml de colorante. Volúmenes mayores de colorante (40-50 ml) se esparcen más medialmente y tiñen el NO y la PL en el 60 % de los casos. Para aumentar la posibilidad de que el colorante se propague a los tres nervios objetivo y al PL del FISI, se recomienda un volumen elevado (≥40 ml) de anestésico. Si solo se requiere un bloqueo de NF y NCFL, un volumen bajo (15-25 ml) de anestésico es suficiente.

Design and application of a new type of fascia stretching cup / 中国针灸

In order to comprehensively stretch human fascia, adjust the biomechanical balance of fascia system and promote the recovery of physiological function of fascia, a new type of fascia stretching cup is designed. This design is composed of two or more silica gel cups and elastic stretching belts between cups. The bottom surface of the silica gel cup has an annular exhaust groove, which can increase the adsorption capacity of the cup to the skin. In the meanwhile, a removable magnet is placed in the groove at the top of each silica gel cup to assist analgesia. This design is suitable for the prevention and treatment of acute and chronic tendon and bone diseases with imbalance of meridians and tendons.

"Two spaces" lateral lymph node dissection based on fascia anatomy for low rectal cancer / 中华胃肠外科杂志

As a treatment of rectal cancer, lateral lymph node dissection (LLND) is still a controversial issue. The argument against LLND is that the procedure is complicated, and consequently results in a high incidence of postoperative urogenital dysfunction. The surgical modality from fascia to space is adopted by lateral lymph node dissection in "two spaces". This operation has significant advantages of clear location of nerves and blood vessels and simplified surgical procedures, so the surgical procedure can be repeated and modulated. The fascia propria of the rectum, urogenital fascia, vesicohypogastric fascia and parietal fascia constitute the dissection plane for lateral lymph node dissection.Two spaces refer to Latzko's pararectal space and paravesical space. During the establishment of fascia plane, the dissection of external iliac lymph node (No.293), commoniliac lymph node (No.273) and abdominal aortic bifurcation lymph node (No.280) can be performed. While in the "space" dissection, internal iliac lymph node (No.263), obturator lymph node (No.283), lateral sacral lymph node (No.260) and median sacral lymph node (No.270) can be removed. LD2 or LD3 lateral lymph node dissection prescribed by the Japanese Society of Colorectal Cancer can be completed according to the needs of the disease. This article describes the anatomical basis and standardized surgical procedures.

Variation of serratus anterior muscle originated from the clavipectoral fascia: a case report / Variación del músculo serrato anterior originado en la fascia clavipectoral: reporte de un caso

SUMMARY: The variations in the serratus anterior (SA) muscle are common. Here, we report a rare variation of the muscle origin with a potentially great clinical implication. We found an aberrant SA variation in an 81-year-old Korean male cadaver during a routine dissection for medical students. Additional slip (AS) of the SA originated from the clavipectoral fascia and the pectoralis minor. It traveled inferiorly and merged to the typical SA part. Precise knowledge about SA variations is clinically valuable; therefore, clinicians should be aware of the possible variation.

RESUMEN: Las variaciones en el músculo serrato anterior (MSA) son comunes. En este trabajo informamos una variación rara del origen muscular con una implicación clínica potencialmente importante. Encontramos una variación aberrante del MSA en un cadáver masculino, coreano de 81 años, durante una disección de rutina para estudiantes de medicina, con un fascículo adicional del MSA originado en la fascia clavipectoral y el músculo pectoral menor. Este fascículo se dirigió inferiormente y se fu- sionó con la parte común de MSA. El conocimiento preciso sobre las variaciones de MSA es útil clínicamente; por lo tanto, los médicos deben ser conscientes de esta posible variación.

Consideraciones sobre afecciones de la fascia endotorácica o peripleura / Considerations for conditions of the endothoracic fascia or peripleura

La tuberculosis de la pared torácica es excepcional y puede presentarse en forma de un absceso frío o una masa seudo tumoral. En ausencia de lesiones pulmonares o extra pulmonares sugerentes de TB, es difícil diferenciar un absceso tuberculoso de un tumor de la pared torácica. Se debe evaluar el diagnóstico de TB de la pared torácica, ante signos clínicos y radiológicos, especialmente en regiones de alta incidencia y prevalencia de la enfermedad. El pronóstico es muy bueno con el tratamiento actual para la TB Si se asocia cirugía para efectuar la resección del absceso, se reducen las complicaciones y/o recurrencias. Si bien su presentación es muy poco frecuente, la Peripleuritis deberá tenerse en consideración Habitualmente se asocia a lesiones pulmonares, linfáticas o costales en actividad Siempre que se conozcan sus caracteres anatomoclínicos, la clínica y la radiología permiten sospechar su diagnóstico.

Tuberculosis of the chest wall is rare and can present in the form of a cold abscess or a pseudo-tumor mass. In the absence of pulmonary or extrapulmonary lesions suggestive of TB, it is difficult to differentiate a tuberculosis abscess from a chest wall tumor. The diagnosis of TB of the chest wall should be evaluated, given clinical and radiological signs, especially in regions of high incidence and prevalence of the disease. The prognosis is very good with the current treatment for TB. If surgery is associated to perform abscess resection, complications and / or recurrences are reduced. Although its presentation is very rare, Peripleuritis should be taken into consideration. Associated with active lung, lymphatic or rib lesions As long as its anatomical-clinical characteristics are known, the clinic and radiology allow suspecting its diagnosis.

O efeito agudo do fst-7 no desempenho, variáveis metabólicas e respostas perceptivas em homens bem treinados / Acute effect of fst-7 on performance, metabolic variables, and perceptual responses in well-trained men

O método Fascia Stretch Training 7 Sets (FST-7) ganhou popularidade nos últimos anos sendo disseminado por fisiculturistas norte-americanos. O objetivo do presente estudo foi comparar os efeitos do protocolo de treinamento do método FST-7 com ou sem alongamento passivo entre as séries nas variáveis metabólicas (lactato [LAC] e creatinofosfoquinase [CPK]), desempenho (volume total de treinamento ­ VTT) e percepção subjetiva de esforço (PSE) em homens bem treinados. Nove homens (23, 2 ± 1,7 anos; 174,2 ± 6,2 cm; 84,6 ± 9,8 kg, 3,4 ± 1,0 anos de experiência em treinamento de força) foram submetidos ao teste e re-teste de 10 repetições máximas (10RM) nos exercícios supino reto livre e crucifixo horizontal com halteres em dias distintos, respeitando 48 horas de intervalo entre a s sessões de teste e re-teste. Decorridas 72 horas do último dia de teste, os participantes realizaram os protocolos experimentais de forma randomizada com 72 horas de intervalo entre as sessões. As coletas sanguíneas foram realizadas 10 minutos antes e imediatamente após os protocolos de treinamento. O protocolo sem alongamento aumentou significativamente a concentração de LAC (p = 0,029). No entanto, o mesmo não ocorreu para a concentração de CPK (p = 0,302). O VTT foi maior para o protocolo sem alongamento (p < 0,001) e a PSE foi maior para o protocolo com alongamento entre as séries (p = 0,003). Concluímos que o método FST-7 com alongamento resultou em uma maior PSE, o que pode estar relacionado com o declínio do desempenho, traduzido pelo menor VTT em relação à condição sem alongamento. Adicionalmente, o menor VTT pode ter afetado o menor acúmulo de LAC observado no método FST-7 com o alongamento. (AU)

The Fascia Stretch Training 7 Sets (FST-7) method has gained popularity in the recent years being disseminated by American bodybuilders. The purpose of the study was to compare the effects of the Fascia Stretch Training 7 Sets (FST-7) method with or without passive stretching between sets on metabolic variables (lactate [LAC] and creatine kinase [CK]), performance (total training volume - TTV) and rating of perceived exertion (RPE) in trained men. For this, nine recreationally trained men (23.2 ± 1.7 years; 174.2 ± 6.2 cm; 84.6 ± 9.8 kg, 3.4 ± 1.0 years of experience in strength training) were submitted to the test and re-test of 10 repetition maximum (10RM) in the barbell bench press and fly with dumbbells on different days, respecting a 48-hour interval between the test and re-test sessions. After 72 hours of the last test day, participants performed the experimental protocols in randomized order with a 72-hour interval between sessions. Blood samples were taken 10 minutes before and immediately after the training protocols. The protocol without stretching was significantly increased LAC concentrations (p = 0.029). However, the same did not occur for the concentration of CK (p = 0.302). The TTV was higher for the protocol without stretching (p < 0.001), and the RPE was significantly higher for the protocol with stretching between sets (p = 0.003). We concluded that the FST-7 method with stretching resulted in higher RPE, which may be related to the decline in performance, translated by the lower TTV in relation to the condition without stretching. This lower TTV may have affected the lower LAC accumulation observed in the FST-7 method with stretching. (AU)

Understanding the anatomy of the Denonvilliers fascia: review article / Compreendendo a anatomia da fáscia de Denonvilliers: artigo de revisão

Abstract The postoperative outcome of rectal cancer has been improved after the introduction of the principles of total mesorectal excision (TME). Total mesorectal excision includes resection of the diseased rectum and mesorectum with non-violated mesorectal fascia (en bloc resection). Dissection along themesorectal fascia through the principle of the "holy plane" minimizes injury of the autonomic nerves and increases the chance of preserving them. It is important to stick to the TME principle to avoid perforating the tumor; violating the mesorectal fascia, thus resulting in positive circumferential resection margin (CRM); or causing injury to the autonomic nerves, especially if the tumor is located anteriorly. Therefore, identifying the anterior plane of dissection during TME is important because it is related with the autonomic nerves (Denonvilliers fascia). Although there are many articles about the Denonvilliers fascia (DVF) or the anterior dissection plane, unfortunately, there is no consensus on its embryological origin, histology, and gross anatomy. In the present review article, I aim to delineate and describe the anatomy of the DVF inmore details based on a review of the literature, in order to provide insight for colorectal surgeons to better understand this anatomical feature and to provide the best care to their patients.

Resumo O resultado pós-operatório do câncer retal foi melhorado após a introdução dos princípios da excisão total do mesorreto (TME, na sigla em inglês). A excisão total do mesorreto inclui a ressecção do reto e do mesorreto afetados com fáscia mesorretal não violada (ressecção em bloco). A dissecção ao longo da fáscia mesorretal pelo princípio do "plano sagrado" minimiza a lesão dos nervos autônomos e aumenta a chance de preservá-los. É importante seguir o princípio da TME para evitar: a perfuração do tumor; a violação da fáscia mesorretal, resultando em margem de ressecção circunferencial (CRM) positiva; ou a lesão aos nervos autônomos, especialmente se o tumor estiver localizado anteriormente. Portanto, a identificação do plano anterior de dissecção durante a TME é importante, pois está relacionada comos nervos autonômicos (fáscia de Denonvilliers). Embora existammuitos artigos sobre a fáscia de Denonvilliers (DVF, na sigla em inglês) ou o plano de dissecção anterior, infelizmente não há consenso sobre sua origem embriológica, histologia e anatomia macroscópica. No presente artigo de revisão, retendo delinear e descrever a anatomia da DVF em mais detalhes com base em uma revisão da literatura, a fim de fornecer subsídios para os cirurgiões colorretais entenderemmelhor esta característica anatômica e fornecer o melhor cuidado para seus pacientes.

Chinese consensus on Denonvilliers' fascia preserving total mesorectal excision (iTME) (2021 version) / 中华胃肠外科杂志

In 1982, total mesorectal excision(TME) was proposed by Professor R. J. Heald, which was a milestone-style for rectal cancer surgery. The concept of TME has reduced the local recurrence rate of mid-low rectal cancer (MLRC) significantly, thus becomes the gold standard for MLRC surgery. However, the incidence of urogenital dysfunction after TME remains high, among which urinary dysfunction reaches 30%-60%, and sexual dysfunction reaches 50%-70%. In recent years, studies have shown that the removal of Denonvilliers' fascia (DVF) during TME is an important cause of postoperative urination and sexual dysfunction. Therefore, DVF preserving total mesorectal excision (iTME) has been recognized by more and more surgical experts. On the basis of existing literature and clinical practice, we organize experts to discuss and vote, put forward recommendations for several issues of iTME, and finally formulate this expert consensus. The formulation of this consensus aims to increase surgeons' awareness of the value and functional protection of DVF during TME surgery, clarify the indications and contraindications of iTME, and standardize the procedure of iTME, so as to reduce postoperative urination and sexual dysfunction and improve the quality of life of patients with MLRC. The level of evidence and recommendation of this consensus is determined by Grading Recommendations, Assessment, Development and Evaluation (GRADE), and the consensus content is determined through expert voting and Delphi method.
