Introduction: The United Kingdom Registry of Endocrine and Thyroid Surgery (UKRETS) holds the largest database of pediatric parathyroidectomy cases globally. There are currently no quoted acceptable cure or complication rates in the literature.

Methods: This retrospective database analysis evaluates the efficacy and safety of targeted parathyroidectomy (tPTx) and bilateral neck exploration (BNE) in first-time parathyroidectomy for pediatric primary hyperparathyroidism (PHPT) through analysis of the UKRETS database (1995-2022).

Background: Many ENT day-case procedures are performed on otherwise healthy individuals in employment. We hypothesised patients' type of employment may affect the amount of time taken off work following such procedures. We aimed to disprove the hypothesis that there is no difference in time taken off between employees and self-employed individuals.

Background: The British Thyroid Association and American Thyroid Association guideline definitions for low-risk differentiated thyroid cancers are susceptible to differing interpretations, resulting in different clinical management in the UK.

Objective: To explore the national effect of these guidelines on the management of low-risk differentiated thyroid cancers.

Methods: Anonymised questionnaires were sent to multidisciplinary teams performing thyroidectomies in the UK.

Objectives: The roles of Allied Health Care Professionals (AHPs) in Head and Neck Cancer (HNC) are wide ranging but not clearly defined. Inter-regional variability in practice results from a lack of standardisation in approaches to the Multidisciplinary Team (MDT) make-up and structure. Traditionally, the follow-up of HNC patients is clinician led with multiple scheduled follow-up appointments.

Objective: The aim of this study was to analyse prospective data on flexible ureteroscopy and laser fragmentation (FURSL) of large stones (> 2 cm) to assess whether a ureteral access sheath (UAS) is necessary for the treatment of large renal stones.

Materials And Methods: Between March 2012 and October 2014, 43 patients with large stones underwent FURSL. Data were collected on a prospective database for patient demographics, stone characteristics and outcomes of FURSL with and without a UAS.

Introduction: The treatment of bilateral renal and/or ureteric stones can be challenging due to concerns about its safety and efficacy compared to staged ureteroscopy. This review evaluates the current evidence to look at the outcomes of bilateral simultaneous ureteroscopy (BS-URS) for urinary stone disease.

Materials And Methods: A systematic review using studies identified by a literature search between January 1990 and August 2013.

Introduction And Objectives: The management of urolithiasis in patients with horseshoe kidney (HSK) is difficult. Stone formation occurred in 1:5 patients with HSK due to impaired urinary drainage and infections. Percutaneous nephrolithotomy and shock wave lithotripsy can be technically challenging due to altered anatomy.

Purpose: With a rising incidence of obesity and urolithiasis, we wanted to look at the outcomes of ureteroscopy (URS) for stone management in this group of patients.

Methods: We did a systematic review of literature in accordance with Cochrane review and preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines on all English language articles between 1990 and June 2015 for URS and stone treatment in obese patients. Data were retrieved for patient and stone demographics, outcomes of URS, complications, and follow-up.

Background And Purpose: The advances in both video games and minimally invasive surgery have allowed many to consider the potential positive relationship between the two. This review aims to evaluate outcomes of studies that investigated the correlation between video game skills and performance in laparoscopic surgery.

Methods: A systematic search was conducted on PubMed/Medline and EMBASE databases for the MeSH terms and keywords including "video games and laparoscopy," "computer games and laparoscopy," "Xbox and laparoscopy," "Nintendo Wii and laparoscopy," and "PlayStation and laparoscopy.

Introduction: Renal lower pole stones pose difficulty in management due to anatomical variation, stone size, hardness and patient demographics. Flexible ureterorenoscopy and laser lithotripsy (FURSL) and shock wave lithotripsy (SWL) are preferred for stones 1-2 cm in size. We wanted to compare the outcomes of FURSL and SWL for lower pole stones during the same time period.

The aim of the present review was to look at the role of ureteroscopy (URS) for treatment of paediatric stone disease. We conducted a systematic review using studies identified by a literature search between January 1990 and May 2013. All English-language articles reporting on a minimum of 50 patients aged ≤ 18 years treated with URS for stone disease were included.

Unlabelled: Robotic radical cystectomy (RRC) has been growing in popularity across the world as a treatment option for bladder cancer.

Objectives: To compare early surgical outcomes for RRC and open radical cystectomy (ORC) with an emphasis on complications and postoperative mortality rates.

Evidence Acquisition: A literature review was conducted from 2000 to 2013, including studies comparing RRC and ORC.

Ureteroscopic management of urolithiasis in pregnancy has been on the rise. Technological advancements such as the development of the semi-rigid or flexible ureteroscope, improvements in the design of baskets used for retrieval and the availability of laser have enabled atraumatic fragmentation of stones. We did a systematic review of literature from January 1990 to December 2012.

Purpose: Diagnosing urinary infection in patients with chronic lower urinary tract symptoms without dysuria is a critical step. In this study we scrutinize the sensitivity and specificity of dipstick urinalysis and microscopic pyuria (10 or more white blood cells per microl) to identify infection in such patients.

Materials And Methods: This was a prospective, blinded, observational cohort study of urological outpatients with painless lower urinary tract symptoms.
