Robotic surgical systems have revolutionized minimally invasive procedures, offering enhanced three-dimensional visualization, high precision, and stable operation, particularly beneficial for radical prostatectomy. However, high costs have hindered the adoption of robot-assisted radical prostatectomy (RARP) in grassroots hospitals in China. This retrospective study aimed to evaluate the efficacy and safety of the EDGE Surgical Robotic System in performing RARP. A total of 129 patients who underwent RARP at our center between November 2023 and March 2025 were analyzed, with outcomes assessed including port placement to docking time, operative time, estimated blood loss, complications, pathological results, safety indicators, length of hospital stay, catheterization duration, postoperative PSA level, and early urinary continence recovery rate. All surgeries were completed successfully without conversion to laparoscopic or open procedures, with a mean setup time of 36.9min, operative time of 176.3min, and estimated blood loss of 128.1 mL. The positive surgical margin (PSM) rate was documented at 31.0%, with an average hospital stay of seven days and catheterization duration of 15.4 days. Importantly, no safety incidents were reported, and the average total cost of hospitalization and operative cost was CNY ¥59854.8 (USD $8287.8) and ¥36,249.2 (USD $5,019.26), respectively, indicating a cost-effective approach. While the study's retrospective design is a limitation, the findings provide preliminary evidence that the EDGE Surgical Robotic System is a safe and economically viable alternative for RARP, paving the way for broader implementation in similar healthcare settings.

Robot-assisted radical prostatectomy (RARP) is a widely used treatment for clinically localised prostate cancer. Preserving neurovascular bundles (NVB), are crucial for erectile function and urinary continence. However, it remains challenging due to accurate identification of the NVB. Branches of the prostatic artery can act as a reference for nerve-sparing (NS) prostatectomy surgery. Due to anatomical variations, vascular mapping utilising CT prostate angiography (CTPA) could assist in prostate artery localisation during RARP, to impact surgical outcomes. This is a hypothesis-generating narrative review in which the anatomy of the prostate, NVB and vasculature is described in addition to the current scope of RARP. CTPA in preoperative planning for RARP is evaluated, with a focus on its potential to enhance preservation of erectile function through improved identification of prostatic vasculature. CTPA is used for pre-procedure planning in prostate artery embolization (PAE) to manage symptomatic benign prostatic hyperplasia (BPH). Currently, pre-procedure planning for NS RARP includes prostate biopsy and MRI for staging. The mainstay of research on RARP is primarily focused on techniques to preserve the NVB, but the role of arterial anatomy warrants additional exploration. Factors such as cost, time and radiation exposure must be considered before CTPA could be included in routine preoperative assessment. By enabling precise identification of critical prostate arterial anatomy, CTPA could facilitate easier localization of the NVB intraoperatively, contributing to improved surgical outcomes. Further investigations are required to ascertain if preoperative CTPA can be a standard to improve functional outcomes and recovery after RARP.

To clarify and statistically analyze the long-term transition of urinary condition and quality of life (QOL) after robot-assisted radical prostatectomy (RARP) using some self-report questionnaires. From May 2017 to June 2021, 243 patients who underwent RARP for prostate cancer at Chiba Tokushukai Hospital were investigated retrospectively. The urinary status was observed for 5years after surgery using the Core Lower Urinary Tract Symptom Score (CLSS), International Prostate Symptom Score (IPSS), Overactive Bladder Symptom Score (OABSS), and International Continence Control Questionnaire-Short Form (ICIQ-SF). We used storage (IPSS-S) and voiding (IPSS-V) items separately for analysis. IPSS-S included "frequency", "urgency", and "nocturia", and IPSS-V included "incomplete emptying", "intermittency", "weak stream", and "straining". The association between the results of the questionnaire and postoperative urinary continence and QOL was examined by statistical analysis. Median values of follow-up duration were 65.5months. Items in almost all questionnaires showed the worst points 1month after surgery and recovered thereafter. All items showed recovery to the baseline level except for "urgency incontinence" and "stress incontinence". Preoperative IPSS-S > 7 was significantly associated with "pad-free" and "1 pad per day" status in multivariate analysis (Hazard ratio = 0.50 and 0.60, P < 0.01 and < 0.01, respectively). Urinary problems other than urinary incontinence can be restored to the baseline level after RARP. QOL differed between patients who showed a "pad-free" status and "1 pad per day" status. Additionally, preoperative IPSS-S was suggested to be a predictor of both "pad-free" status and "1 pad per day" status after surgery.

The rapid adoption of robotic abdominal surgery has necessitated structured training programs to ensure surgeon competence and patient safety. The da Vinci TR 100-200-300-400-500 training system represents a comprehensive pathway for developing robotic surgical skills, yet its effectiveness on learning curves remains incompletely characterized. A systematic review was conducted following PRISMA guidelines, searching PubMed, Embase, and Cochrane databases from inception to October 2025. Studies evaluating learning curves associated with the TR training system in robotic abdominal surgery were included. Data extraction focused on training methodologies, assessment parameters, learning curve patterns, and clinical outcomes. The search identified 1,591 records, with 17 studies meeting inclusion criteria. The TR training system demonstrates a progressive learning curve across its modules: TR 100 (technical skills foundation), TR 200 (technical-clinical integration), TR 300 (procedure application), TR 400 (procedure refinement), and TR 500 (mastery). Significant learning occurs within 5-10 repetitions for basic skills, with 90% expert-level performance achieved by 53% of novices after 10 repetitions. Key parameters showing improvement include overall score, time to completion, instrument collision, and critical errors. The TR 100-200-300-400-500 training system provides an effective structured pathway for developing robotic abdominal surgery skills. However, standardization of assessment methods and validation of skill transfer to clinical performance require further investigation.

Despite the rapid rise of short-video platforms as health information sources, the informational quality of robotic-surgery videos-an area requiring precise clinical explanation-remains insufficiently studied. To compare the quality and reliability of robotic-surgery videos on TikTok and Bilibili and determine how platform features and uploader identity shape content quality. We conducted a cross-sectional analysis of 200 videos (100 per platform) scored using the Global Quality Score (GQS) and modified DISCERN (mDISCERN). Videos were coded by uploader type and theme, and group differences and predictors were examined with nonparametric tests and multivariable regression. TikTok videos drew more engagement, but Bilibili posts were longer and scored higher on GQS and mDISCERN. Professional uploaders produced the most reliable content. Engagement metrics correlated with each other yet did not predict quality in regression. On short-video platforms, visibility and scientific accuracy diverge-highlighting the need for professional involvement, quality-sensitive governance, and stronger public digital health literacy.
