Abstract Development of chronic postsurgical pain following major abdominal or pelvic surgeries is increasingly recognized. Multimodal analgesia including regional anesthesia such as rectus sheath block is growing in popularity. While the literature mainly describes ultrasound-guided rectus sheath blocks, there are many advantages to surgicallyinitiated rectus sheath catheter performed at the end of surgery. In this technical description, we describe the rationale and technique of surgical insertion of rectus sheath catheters following major urologic surgery with midline incision which is routinely performed by urologists at our institution. Furthermore, we would like to highlight the type of catheter More >

Abstract Reservoir induced bladder rupture is a rare complication of inflatable penile prosthesis (IPP) revision surgery. Our aim is to review the literature and describe our experience with this complication using two case reports that involved reusing an in-situ reservoir. In each case, an episode of gross hematuria indicated that a bladder rupture had occurred. From our experience, we propose ways to possibly avoid and if necessary, manage this rare complication.

Abstract Introduction: The COVID-19 pandemic disrupted medical student education and posed a unique challenge for educators, especially for surgical clerkships. In response to COVID-19 rotation restrictions, we implemented a virtual urologic surgery sub-internship program and evaluated medical student impressions of the experience.
Materials and methods: A two-week urology curriculum was created with content delivered by interactive videoconferencing. The curriculum included synchronous and individual learning with live patient clinical experiences in the outpatient clinic and operating room, lectures, departmental conferences, a suture lab, self-reflective writing exercises, and an oral presentation. Student impressions were assessed with an exit survey. Descriptive… More >

Abstract Introduction: The purpose of this study was to describe the current incidence, risk factors, and management of incidental diagnosis of prostate cancer (iPCa) among patients who underwent holmium laser enucleation of prostate (HoLEP) and have no history of prostate cancer.
Materials and methods: We conducted a retrospective review of all patients who underwent HoLEP in our institution between 2013-2020. All patients were offered a PSA screening according to the latest guidelines. We gathered demographic data, perioperative information, and pathologic evaluation. For patients diagnosed with iPCa, we gathered work up, management, and oncologic outcome. We then conducted a… More >

Abstract Introduction: The AUA guidelines for benign prostatic hyperplasia distinguish treatments based upon prostate volume (PV), particularly for very large prostates (> 150 mL). While the clinical outcomes and benefits of Aquablation have been studied for men with average and large prostates, it is unknown whether this technology can be used for very large prostates.
Materials and methods: Men with PV > 150 mL undergoing Aquablation were identified retrospectively from four North American hospitals. The surgical times and clinical outcomes of men with very large prostates (> 150 mL) were compared to data from men with average PV… More >

Abstract A single coronary artery is a very rare condition, commonly associated with other congenital anomalies. It could be generally considered as neither benign nor malignant form of congenital coronary artery anomalies since its pathophysiological and clinical implications grossly depend on different anatomical patterns defined by the site of origin and distribution of the branches. By presenting the patient who underwent successful coronary artery bypass grafting and aortic valve replacement surgery in a presence of isolated single coronary artery, we intend to emphasize natural and procedural risks and distinguish casual from causal in this extremely rare More >

Abstract Cardioplegia has been widely used to reduce myocardial injury during pediatric cardiac surgery; however, which cardioplegia solution has the best protective effect has not been established. Thus, we compared the myocardial protective effects of different cardioplegia solutions used in pediatric cardiac surgery. Seven databases were searched to identify the relevant randomized controlled trials. A network meta-analysis with a Bayesian framework was conducted. The outcomes included the following biochemical and clinical outcomes: serum concentrations of the creatine kinase-myocardial band at 6 h postoperatively; cardiac troponin I (cTnI) at 4, 12, and 24 h postoperatively; spontaneous beating… More >

Abstract In the simulation of acupuncture manipulation, it is necessary to accurately capture the information of acupuncture points and particles around them. Therefore, a soft tissue modeling method that can accurately track model particles is needed. In this paper, a soft tissue acupuncture model based on the mass-spring force net is designed. MSM is used as the auxiliary model and the SHF model is combined. SHF is used to establish a three-layer soft tissue model of skin, fat, and muscle, and a layer of the MSM based force network is covered on the surface of soft More >

Abstract Pentalogy of Cantrell is a rare congenital abnormality. Even with high-quality medical care and staged corrective surgeries in professional hospitals, the mortality rate is still very high and long-term prognosis is poor. Survival is largely determined by the complexity and severity of cardiac abnormalities, the efficiency of abdominal wall closure and postoperative complications. A 24-year-old male patient with complete pentalogy of Cantrell was diagnosed. One-stage surgical repair of all abnormalities were completed. The patient recovered well and had been follow-up for 7 years. He has a good cosmetic outcome, with no signs of cardiac dysfunction. More >

Abstract The cutting simulation of soft tissue is important in virtual surgery. It includes three major challenges in computation: Soft tissue simulation, collision detection, and handling, as well as soft tissue models. In order to address the earlier challenges, we propose a virtual cutting system based on the mass-spring model. In this system, MSM is utilized to simulate the soft tissue model. Residual stress is introduced to the model for simulating the shrinking effect of soft tissue in cutting. Second, a cylinder-based collision detection method is used to supervise the collision between surgical tools and soft More >
