Background: Almost half of all women will have at least one symptomatic urinary tract infection (UTI) in their lifetime. Although usually self-remitting, 74% of women contacting a health professional are prescribed an antibiotic, and in rare instances, they may progress to more severe infections. Therefore, the standard of care for the treatment of symptomatic uncomplicated UTIs is oral antibiotic therapy, which aims to achieve symptom resolution and prevent the development of complications such as pyelonephritis.

Background: Urodynamic evidence of storage dysfunction such as detrusor overactivity (DO) and/or poor compliance are present in up to 30-40% of patients after Radical Prostatectomy (RP). However, the current optimal management of men with DO on preoperative urodynamics prior to male stress urinary incontinence (SUI) surgery is not known.

Methods: We performed a systematic search of the literature including articles on patients undergoing SUI surgery after prostatectomy with preoperative DO between January 2003 and May 2023 to ensure contemporaneous data was obtained.

Background: Stress urinary incontinence imposes a significant health and economic burden on individuals and society. Single-incision slings are a minimally-invasive treatment option for stress urinary incontinence. They involve passing a short synthetic device through the anterior vaginal wall to support the mid-urethra.

Context: Overactive bladder syndrome (OAB) is highly prevalent among women and has a negative impact on their quality of life. The current available treatments for OAB symptoms include conservative, pharmacological, or surgical modalities.

Objective: To provide an updated contemporary evidence document regarding OAB treatment options and determine the short-term effectiveness, safety, and potential harms of the available treatment modalities for women with OAB syndrome.

Objectives: To develop a nomogram that could predict spontaneous stone passage (SSP) in patients presenting with acute ureteric colic who are suitable for conservative management.

Subject/patients: A 2517 patient dataset was utilised from an international multi-centre cohort study (MIMIC, A Multi-centre Cohort Study Evaluating the role of Inflammatory Markers In Patients Presenting with Acute Ureteric Colic) of patients presenting with acute ureteric colic across 71 secondary care hospitals in the United Kingdom, Ireland, Australia, and New Zealand. Inclusion criteria mandated a non-contrast CT-KUB.

Background: Patient factors associated with urinary tract cancer can be used to risk stratify patients referred with haematuria, prioritising those with a higher risk of cancer for prompt investigation.

Objective: To develop a prediction model for urinary tract cancer in patients referred with haematuria.

Design, Setting, And Participants: A prospective observational study was conducted in 10 282 patients from 110 hospitals across 26 countries, aged ≥16 yr and referred to secondary care with haematuria.

Context: Female lower urinary tract symptoms (LUTS) are a common presentation in urological practice. Thus far, only a limited number of female LUTS conditions have been included in the European Association of Urology (EAU) guidelines compendium. The new non-neurogenic female LUTS guideline expands the remit to include these symptoms and conditions.

Context: While the management of bladder outlet obstruction (BOO) in men has been a topic of several systematic reviews and meta-analyses, no such evidence base exists for female BOO.

Objective: The aim of this systematic review was to evaluate the benefits and harms of therapeutic interventions for the management of BOO in women.

Evidence Acquisition: This systematic review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) statement.

Context: Female bladder outlet obstruction (fBOO) is a relatively uncommon condition compared with its male counterpart. Several criteria have been proposed to define fBOO, but the comparative diagnostic accuracy of these remains uncertain.

Objective: To identify and compare different tests to diagnose fBOO through a systematic review process.

Context: White light (WL) cystoscopy and transurethral resection of bladder tumour (TURBT) comprise the current gold standard technique for detecting and grading bladder cancer. However, with WL cystoscopy, recurrence following initial TURBT is high, and identification of smaller tumours and carcinoma in situ is poor. Photodynamic diagnosis (PDD) has been developed to improve the detection of bladder.

Objective: To evaluate the contemporary prevalence of urinary tract cancer (bladder cancer, upper tract urothelial cancer [UTUC] and renal cancer) in patients referred to secondary care with haematuria, adjusted for established patient risk markers and geographical variation.

Patients And Methods: This was an international multicentre prospective observational study. We included patients aged ≥16 years, referred to secondary care with suspected urinary tract cancer.

Introduction: In kidney transplantation, total laparoscopic live donor nephrectomy (TLLDN) in the presence of multiple renal arteries (MRA) is technically challenging and has traditionally been associated with higher complication rates. We report our experience of using MRA grafts procured by TLLDN.

Materials And Methods: Patients undergoing TLLDN at our center (2004-2014) was identified from a prospectively maintained database and divided into single renal arteries (SRA) or MRA groups.

Context: The role of multiparametric magnetic resonance imaging (mp-MRI) during active surveillance (AS) of prostate cancer needs evaluation. It remains unclear whether mp-MRI can replace prostate biopsies completely during AS.

Objective: To evaluate the diagnostic performance of mp-MRI for disease progression in men on AS for prostate cancer.

Context: Acute testicular torsion is a common urological emergency. Accepted practice is surgical exploration, detorsion, and orchidopexy for a salvageable testis.

Objective: To critically evaluate the methods of orchidopexy and their outcomes with a view to determining the optimal surgical technique.

Context: Inconsistent reporting of effectiveness outcomes in surgical trials of stress urinary incontinence (SUI) has hindered direct comparisons of various surgical treatments for SUI.

Objective: To systematically review the verbatim outcome names, outcome definitions, and tools used to measure the outcomes in surgical trials of SUI in women.

Evidence Acquisition: Trials of women with SUI who have undergone surgical interventions were included.

Context: Nocturia is a prevalent symptom with varied aetiology and no consensus on treatment options.

Objective: We systematically reviewed evidence comparing the benefits and harms of various treatment options for nocturia or nocturnal incontinence in women.

Evidence Acquisition: Literature search was performed using Embase, Medline, and Cochrane databases (from 1 January 1946 to 26 September 2017), following the methods detailed in the Cochrane Handbook.

Context: Retzius sparing robotic assisted radical prostatectomy appears to have better continence rates when compared to conventional robotic assisted radical prostatectomy, however, concern with high positive surgical margin rates exist.

Objective: To systematically evaluate evidence comparing functional and oncological outcomes of retzius sparing robotic assisted radical prostatectomy and conventional robotic assisted radical prostatectomy.

Evidence Acquisition: The systematic review was performed in accordance with the Cochrane guidelines and the preferred reporting items for systematic reviews and meta-analyses (PRISMA).

Objectives: To assess the relationship of white blood cell count (WBC) and other routinely collected inflammatory and clinical markers including stone size, stone position, and medical expulsive therapy use (MET), with spontaneous stone passage (SSP) in a large contemporary cohort of patients with acute ureteric colic, as there are conflicting data on the role of WBC and other inflammatory markers in SSP in patients with acute ureteric colic.

Patients And Methods: Multicentre retrospective cohort study coordinated by the British Urology Researchers in Surgical Training (BURST) Research Collaborative at 71 secondary care hospitals across four countries (UK, Republic of Ireland, Australia, and New Zealand). In all, 4170 patients presented with acute ureteric colic and a computed tomography confirmed single ureteric stone.
