The paper introduces Professor FANG Yigong 's experience in treating pelvic congestion syndrome with acupuncture. Professor FANG believes that the stagnation in the thoroughfare and conception vessels, retarded circulation of qi and blood, and the obstruction of blood flow in the uterus are implicated in the pathogenesis of pelvic congestion syndrome. In clinical practice, according to the pathogenesis, focusing on regulating the functions of the thoroughfare and conception vessels, the thinking of treatment is summarized as "resolving the stasis and stopping pain by regulating the thoroughfare and conception vessels", "selecting the points based on their indications" and "tranquilizing the mind and harmonizing the physical and mental states". The main points are Baihui (GV20), Shenting (GV24), Benshen (GB13), Zhongwan (CV12), Tianshu (ST25), Guanyuan (CV4), Dahe (KI12), and Zigong (EX-CA1). The supplementary points are used in terms of the etiology and symptoms. During acupuncture, attention should be paid to the application of Xiaoyao Tiaoshen technique of acupuncture and mutual harmonization of the mind in acupuncture operator and patient. This summary may provide a new approach to the treatment of pelvic congestion syndrome.

Adolescent idiopathic scoliosis (AIS) is a common spinal deformity in adolescents, with potential causes etiologies associated with mesenchymal stem cells, genetic factors, histological features, and biomechanical aspects. Biomechanically, the pelvis, serving as the central and majort load-bearing structure, exhibits morphological and alignment abnormalities highly correlated with the development of AIS. Recent studies have extensively explored three-dimensional pelvic parameters and kinematics, demonstrating that abnormal pelvic characteristics may contribute to AIS onset and progression and are increasingly incorporated into clinical interventions. This review summarizes sagittal and coronal features of the spine-pelvis, as well as the influence of three-dimensional kinematic features on the pathogenesis of AIS, providing insights for advancing the study of spine-pelvis features related to AIS.

Recent studies have revealed a significant relationship between erectile dysfunction (ED) and lower urinary tract symptoms (LUTS), both of which commonly affect middle-aged and older men. These conditions share underlying causes, particularly endothelial dysfunction, atherosclerosis, and chronic pelvic ischemia (CPI). This study investigated the therapeutic potential of LDD175, a large-conductance Ca 2+ -activated K + channel (BKCa channel) opener, in simultaneously treating both conditions using a CPI animal model of male Sprague Dawley rats. Our study investigated the induction of CPI through surgical endothelial damage combined with a high-cholesterol diet. We assessed erectile and voiding functions by measuring intracavernosal pressure (ICP) and intraurethral pressure (IUP), respectively, after nerve stimulation. We performed histological examinations of vascular changes and western blot analyses of cavernous and prostate tissues to understand the underlying mechanisms. This study evaluated the effectiveness of LDD175 compared to standard treatments, such as sildenafil for ED and tamsulosin for LUTS. Therefore, the CPI model successfully demonstrated ED and LUTS symptoms with decreased ICP and increased IUP. Analysis revealed elevated levels of hypoxia-inducible factor-1α, transforming growth factor-β1 and β2 in cavernous tissue, and increased α1A-adrenoceptor expression in prostate tissue. LDD175 administration showed promising results, with dose-dependent improvements in ICP and IUP, and therapeutic effects comparable to those of established treatments. Our findings suggest a novel therapeutic approach that can simultaneously address ED and LUTS, opening new possibilities for clinical application in the treatment of these interconnected conditions.

Objective： The aim of this study is to explore the predictive value of biparametric magnetic resonance imaging(bpMRI)for pelvic lymph node metastasis in prostate cancer patients with PSA≤20 μg/L and establish a nomogram. Methods： The imaging data and clinical data of 363 patients undergoing radical prostatectomy and pelvic lymph node dissection in the First Affiliated Hospital of Nanjing Medical University from July 2018 to December 2023 were retrospectively analyzed. Univariate analysis and multivariate logistic regression were used to screen independent risk factors for pelvic lymph node metastasis in prostate cancer, and a nomogram of the clinical prediction model was established. Calibration curves were drawn to evaluate the accuracy of the model. Results： Multivariate logistic regression analysis showed extrocapusular extension (OR=8.08,95%CI=2.62－24.97, P<0.01), enlargement of pelvic lymph nodes (OR=4.45,95%CI=1.16－17.11,P=0.030), and biopsy ISUP grade(OR=1.97,95%CI=1.12－3.46, P=0.018)were independent risk factors for pelvic lymph node metastasis. The C-index of the prediction model was 0.834, which indicated that the model had a good prediction ability. The actual value of the model calibration curve and the prediction probability of the model fitted well, indicating that the model had a good accuracy. Further analysis of DCA curve showed that the model had good clinical application value when the risk threshold ranged from 0.05 to 0.70.Conclusion： For prostate cancer patients with PSA≤20 μg/L, bpMRI has a good predictive value for the pelvic lymph node metastasis of prostate cancer with extrocapusular extension, enlargement of pelvic lymph nodes and ISUP grade≥4.

With the development of surgical techniques, adjuvant therapy and neoadjuvant therapy, the survival time of rectal cancer patients after surgery has been significantly improved, but organ dysfunction is still an important problem affecting the quality of life of patients after surgery. With the continuous deepening of clinical research and practice and the updating of relevant theories, more detailed and reliable evidence-based medical evidence has been accumulated in the field of pelvic organ function protection in rectal cancer surgery, and has been continuously verified in the clinical real world at home and abroad. In order to further improve the awareness of domestic physicians on the protection of organ function during the treatment of rectal cancer, standardize the evaluation methods and surgical methods, reduce the incidence of organ dysfunction, and thus improve the quality of life of patients, Society of Colon & Rectal Surgeons of Chinese College of Surgeons of Chinese Medical Doctor Association, Section of Colorectal Surgery of Branch of Surgery of Chinese Medical Association, National Health Commission Capacity Building and Continuing Education Center Colorectal Surgery Committee, and Colorectal and Anal Function Surgeons Committee of China Sexology Association organized the discussion among relevant experts. On the basis of the 2021 edition of the Chinese Expert Consensus on the Protection of Pelvic Organ Function in Rectal Cancer Surgery, the recent evidence-based medical evidence was analyzed and summarized, and the definition, risk factors, evaluation methods, prevention and other issues of organ dysfunction after rectal cancer surgery were analyzed with reference to relevant domestic and foreign studies and combined with clinical practice. Proposed the diagnosis, evaluation and treatment of pelvic organ dysfunction in rectal cancer surgery, and finally formed the "Chinese expert Consensus on the protection of pelvic organ function in rectal cancer surgery (version 2025)".

OBJECTIVE: To explore the clinical significance of extended pelvic lymph node dissection (EPLND) under the robot-assisted laparoscope in the treatment of high-risk PCa. METHODS: This study included 29 cases of high-risk PCa treated by robot-assisted laparoscopic radical prostatectomy and EPLND from April 2020 to January 2023. We collected the general data on the patients, recorded the status of dissection of the lymph nodes and postoperative complications, and analyzed the significance of EPLND. RESULTS: The patients were aged (69.3±6.6) years old, with the preoperative PSA level of 8.43－434 μg/L, Gleason score (GS) 6 in 1, GS 7 in 9, and GS ≥8 in 19 cases. The operation time averaged (97.2±15.7) min, with the mean blood loss of (30.5±11.2) ml, and 3－42 (median = 13) lymph nodes dissected, less than 10 in 10 cases, 11－19 in 12, and more than 20 in 7. Positive pelvic lymph nodes (median = 4) were found in 13 cases, with a positive rate of 44.8%. Positive incisal margin was observed in 11 cases (37.9%), lymphovascular invasion (LVI) in 4 (13.8%), and perineural invasion (PNI) in another 4 (13.8%). Lymph node metastasis was significantly correlated with positive incisal margin (P<0.05), but not with LVI, PNI or age (P>0.05). No significant vascular or nerve injuries occurred during the operation. GS 6 was detected in 1, GS 7 in 7, and GS ≥8 in 21 cases postoperatively. CONCLUSION Robot-assisted laparoscopic EPLND is an important strategy for the treatment of high-risk PCa, which contributes to accurate pathological staging of the malignancy. However, evidence is lacking for its benefit to the survival of high-risk PCa patients, and more follow-up studies are needed to confirm its treatment effect.

Conformal sphincter-preservation operation (CSPO) is considered the effective surgical technique for preserving the sphincter in cases of low rectal cancer. Accurate preoperative diagnosis and staging, reasonable selection of surgical approaches and technique, standardized perioperative management, and postoperative rehabilitation are the keys to ensuring the oncological clearance and functional preservation of CSPO. However, there is currently a lack of standardized surgical procedure for implementing CSPO in China. Therefore, the Colorectal Surgery Group of Surgery Branch of the Chinese Medical Association,along with the Colorectal Cancer Committee of the Chinese Medical Doctor Association and the Anorectal Branch of Chinese Medical Doctor Association, gathered experts in colorectal surgery to discuss and establish this standardized surgical procedure of CSPO. This standard, based on the latest evidence from literature, expert experiences, and China national condition, focuses on the definition, classification, pelvic anatomy, surgical techniques, postoperative complications, and perioperative care of CSPO. It aims to guide the standardized clinical practice of CSPO in China.

OBJECTIVES: To investigate the reliability and accuracy of deep learning technology in automatic sex estimation using the 3D reconstructed images of the computed tomography (CT) from the Chinese Han population. METHODS: The pelvic CT images of 700 individuals (350 males and 350 females) of the Chinese Han population aged 20 to 85 years were collected and reconstructed into 3D virtual skeletal models. The feature region images of the medial aspect of the ischiopubic ramus (MIPR) were intercepted. The Inception v4 was adopted as the image recognition model, and two methods of initial learning and transfer learning were used for training. Eighty percent of the individuals' images were randomly selected as the training and validation dataset, and the remaining were used as the test dataset. The left and right sides of the MIPR images were trained separately and combinedly. Subsequently, the models' performance was evaluated by overall accuracy, female accuracy, male accuracy, etc. RESULTS: When both sides of the MIPR images were trained separately with initial learning, the overall accuracy of the right model was 95.7%, the female accuracy and male accuracy were both 95.7%; the overall accuracy of the left model was 92.1%, the female accuracy was 88.6% and the male accuracy was 95.7%. When the left and right MIPR images were combined to train with initial learning, the overall accuracy of the model was 94.6%, the female accuracy was 92.1% and the male accuracy was 97.1%. When the left and right MIPR images were combined to train with transfer learning, the model achieved an overall accuracy of 95.7%, and the female and male accuracies were both 95.7%. CONCLUSIONS The use of deep learning model of Inception v4 and transfer learning algorithm to construct a sex estimation model for pelvic MIPR images of Chinese Han population has high accuracy and well generalizability in human remains, which can effectively estimate the sex in adults.

A locked pubic ramus body is an unusual variant of lateral compression injury. Till date, there have been only 25 cases reported in the published literature. We herein described a case where the right pubic ramus was entrapped within the opposite obturator foramen with an overlap of greater than 4 cm, with associated urethral injury. When all maneuvers of closed and instrumented reduction failed, we performed a superior pubic ramus osteotomy on the left side and unlocked the incarcerated right pubic ramus. The osteotomy site was stabilized with a 6-hole recon plate. The patient underwent delayed urethral repair 10 weeks after the index surgery. At 3-year follow-up, the patient has sexual dysfunction especially difficulty in maintaining erection, secondary urethral stricture, heterotopic ossification, and breakage of implants.

Leiomyosarcoma of urinary bladder (LMS-UB) is a highly malignant mesenchymal tumor, accounting for less than 0.5% of all bladder malignancies, with a predominant clinical presentation of hematuria. Here we report a case of low-grade LMS-UB. A 44-year-old male patient was admitted to the hospital with urodynia for 2 weeks. The patient's pelvis CT showed a mass on the right part of the bladder. For this reason, he was initially diagnosed with bladder cancer. We performed a robot-assisted laparoscopic enucleation of the bladder tumor and low-grade LMS-UB was diagnosed with the histopathological examination. He underwent 5 cycles of adjuvant chemotherapy after surgery. At 19months postoperative follow-up, the patient had no symptoms, recurrence, or distant metastasis. There is no report on the treatment of LMS-UB with minimally invasive enucleation worldwide. This case provides a new comprehensive treatment method of enucleation combined with adjuvant chemotherapy for early low-grade LMS-UB to reduce complications and improve patients' quality of life after surgery.
