Objectives: To evaluate the Versius surgical system for robot-assisted prostatectomy in a preclinical cadaveric model using varying system setups and collect surgeon feedback on the performance of the system and instruments, in line with IDEAL-D recommendations.
Materials And Methods: Procedures were performed in cadaveric specimens by consultant urological surgeons to evaluate system performance in completing the surgical steps required for a prostatectomy. Procedures were conducted using either a 3-arm or 4-arm bedside unit (BSU) setup.
We report an extremely rare case of locally advanced prostate cancer in a phenotypic male patient with persistent müllerian duct syndrome. The patient underwent a robot-assisted retzius-sparing radical prostatectomy, bilateral pelvic lymph node dissection, radical hysterectomy, vaginectomy, and salpingo-ophorectomy. He was continent at 3 months follow-up.

Objective: To describe the procedure and show the accuracy and tolerability of a novel Vector MRI/ultrasound fusion transperineal (TP) biopsy technique that uses electromagnetic (EM) needle tracking under local anaesthesia (LA).

Importance: Robot-assisted radical cystectomy is being performed with increasing frequency, but it is unclear whether total intracorporeal surgery improves recovery compared with open radical cystectomy for bladder cancer.
Objectives: To compare recovery and morbidity after robot-assisted radical cystectomy with intracorporeal reconstruction vs open radical cystectomy.
Design, Setting, And Participants: Randomized clinical trial of patients with nonmetastatic bladder cancer recruited at 9 sites in the UK, from March 2017-March 2020.
Purpose: Our aim was to report the positive surgical margin (PSM) rate of Retzius-sparing robot-assisted radical prostatectomy (RS-RARP) in an unselected, real-life cohort of patients treated at a fellowship-training urological department.
Materials And Methods: Demographic, clinical and pathological data of 529 consecutive patients who underwent RS-RARP between January 2017 and December 2020 were collected prospectively and analyzed retrospectively in a hospital-approved audit in a European Association of Urology Robotic Urology Section (ERUS)-approved fellowship program. Overall PSM rates were reported for the entire cohort and for pT2 and pT3 patients separately.
Hypoxia-inducible factors, HIF-1α and HIF-2α, are expressed in the majority of clear-cell renal cell carcinoma (CC-RCC). In vitro, HIFα isoforms regulate a differential set of genes, and their effects in vivo within CC-RCC tumours may affect outcome. The role of angiogenesis and HIFα transcriptional products, including those involved in cell metabolism and morphological dedifferentiation have not been extensively investigated and might have relevance to the development of antiangiogenic or anti-HIFα trials in primary CC-RCC, either before or after radical nephrectomy.
View Article and Find Full Text PDFObjective: To develop a relational database (Cancer Research Uro-Oncology Database, CRUD) to enable automatic data collection on all urological malignancies within our region, as there is increasing emphasis on good data collection for surgical patients with cancer, and numerous overlapping systems that are amassing data on the same patients.
Methods: Links have been established between pathological databases, multidisciplinary team data-collection systems and patient-survival monitoring facilities, providing accurate pathology, treatment and survival data on all of uro-oncology patients. We are also developing individual modules for the oncological surgeons within our unit that are compatible with the British Association of Urological Surgeons (Section of Oncology), and have plans to connect to the Medical and Clinical Oncology data systems in the future.
Angiogenesis is critical for growth of tumors and their metastasis. In this article we review the literature on studies of angiogenesis pathways and markers for renal cancer, prostate cancer and bladder cancer. Overall, there is clear evidence that markers of angiogenesis and expression of angiogenic factors are associated with adverse outcomes in each of these tumor types.
