Objectives
To evaluate the feasibility and safety of robotic‐assisted salvage radical cystectomy (RA‐SRC).
Materials and Methods
We retrospectively searched the prospectively collected surgical database of two highly experienced robotic urological surgeons for cases of RA‐SRC, defined as RARC performed post‐previous pelvic RT for palliative or onc...
Background and objective
Although prostate-specific membrane antigen (PSMA) positron emission tomography/computed tomography (PET/CT) has impacted the investigation and management of biochemical recurrence (BCR) of prostate cancer, negative scans are common at low rising prostate-specific antigen (PSA) levels. PET/CT devices with an extended axial...
Introduction
Radical prostatectomy (RP) remains a leading cause of erectile dysfunction (ED), primarily due to the inevitable damage to the cavernous nerves. Despite technical improvements in nerve-sparing surgery, post-prostatectomy rates of erectile dysfunction remain unacceptably high. Low-intensity electrostimulation (LIES) has been demonstrate...
Background: Multiparametric magnetic resonance imaging (mpMRI) is now the standard of care to guide prostate biopsies during workups and assessment of men with suspected prostate cancer (PCa). In addition to intraprostatic lesion detection, MRI usually covers the bony pelvis and pelvic lymph nodes, two of the commonest sites for metastatic disease....
Robotic surgery has expanded internationally at pace. There are multiple local robotic training pathways but there is inconsistency in standardisation of core common components for curricula internationally. A framework is required to define key objectives that can be implemented across robotic training ecosystems. This Delphi consensus aimed to pr...
Simple Summary
In this study, we investigated the impact of lymphovascular invasion at the time of prostatectomy on oncological outcomes in patients with prostate cancer. We found that the presence of lymphovascular invasion at the time of radical prostatectomy is associated with aggressive prostate cancer disease features and is an indicator of po...
BACKGROUND
The benefits of a robot-assisted radical cystectomy (RARC) compared to an open approach is still under debate. Initial data on RARC were from trials where urinary diversion was performed by an extracorporeal approach, which does not represent a completely minimally invasive procedure. There are now updated data for RARC with intracorpore...
Background
The surgical difficulty of partial nephrectomy (PN) varies depending on the operative approach. Existing nephrometry classifications for assessment of surgical difficulty are not specific to the robotic approach.
Objective
To develop an international robotic-specific classification of renal masses for preoperative assessment of surgical...
Context
Surgical outcomes and patient morbidity are often surrogate markers of health care quality and efficiency. These parameters can only be used with confidence if the reporting and grading of intra- and postoperative complications are reliable and reproducible. Without uniformity and regulation, the risk of under-reporting, and thus significan...
Background:
The introduction of robotic surgical systems has significantly impacted urological surgery, arguably more so than other surgical disciplines. The focus of our study was length of hospital stay - patients have traditionally been discharged day 1 post-robot-assisted radical prostatectomy (RARP), however, during the ongoing COVID-19 pande...

Background:
The term local recurrence in prostate cancer is considered to mean persistent local disease in the prostatic bed, most commonly at the site of the vesicourethral anastomosis (VUA). Since the introduction of prostate-specific membrane antigen (PSMA) positron emission tomography/computed tomography (PET/CT) and magnetic resonance imaging...
Background
: Disease recurrence is common following prostatectomy in patients with localised prostate cancer with high-risk features. Although androgen deprivation therapy increases the rates of organ-confined disease and negative surgical margins, there is no significant benefit on disease recurrence. Multiple lines of evidence suggest that FGF/FG...

71 Background: Androgen receptor splice variants (ARvs) are upregulated in response to castration, and can activate transcription in the absence of ligand. Recent evidence indicates that CTC ARv7 expression is an accurate predictor of absence of response to abiraterone and enzalutamide, providing strong clinical support for ARv7 upregulation as pot...
Introduction
Renal angiomyolipoma (AML) is a benign mesenchymal tumour of the kidney with a tendency of aneurysm formation at risk of rupturing. Due to increased maternal circulation and hormonal influences, rupture risk is greater in pregnancy, often leading to a vascular emergency and premature delivery or termination.
Presentation of case
A 24-...
There is growing interest in the use of trans-perineal template biopsy for the diagnosis of prostate cancer. This is principally due to the reduced sepsis rate and improved diagnostic accuracy when compared with transrectal prostate biopsy. However, the need for a brachytherapy stepper and template are limiting factors. Here we discuss trans-perine...
Culture is performed in patients presenting with symptoms of urinary tract infection in order to confirm diagnosis, identify the infecting organism(s), and determine antibiotic sensitivities.
There are two ways in which urine is cultured: split agar, which is the most commonly employed method, and dipslide, which is a cheaper and simpler alternativ...
Vulvar hematomas occur rarely outside the obstetric population but may present after other trauma to the pelvis or perineum. Spontaneous rupture of the internal iliac artery is described mostly in the presence of an aneurysm, with atherosclerosis, connective tissue disease, infection, and trauma as causative factors. It most often presents with abd...
Endoscopic retrograde cholangiopancreatography (ERCP) is an important procedure for the investigation and management of pancreaticobiliary disease. There is a recognized potential for significant morbidity, and a number of studies have identified patient and operator risk factors for the development of complications, including small case volume. We...
Noncontrast spiral CT (NCCT) has emerged as the investigation of choice in patients presenting with renal-tract calculi. As management guidelines are based on stone size measured on plain radiography of the kidneys, ureters, and bladder (KUB), it is important to assess the accuracy of stone size measured on NCCT compared with KUB films.
The NCCT an...
Paragangliomas are rare tumours of the autonomic nervous system that occur in both sporadic and hereditary forms. They are usually benign tumours with low mortality, but can cause significant morbidity related to mass effect. Genetic predisposition to develop paraganglioma can occur within known tumour syndromes and familial tumours tend to present...
