Cost-utility analysis of shockwave lithotripsy vs ureteroscopic stone treatment in adults.

Objectives: To assess the cost-effectiveness, resource use implications, quality-adjusted life-years (QALYs) and cost per QALY of care pathways starting with either extracorporeal shockwave lithotripsy (SWL) or with ureteroscopic retrieval (ureteroscopy [URS]) for the management of ureteric stones.

Patients And Methods: Data on quality of life and resource use for 613 patients, collected prospectively in the Therapeutic Interventions for Stones of the Ureter (TISU) randomized controlled trial (ISRCTN 92289221), were used to assess the cost-effectiveness of two care pathways, SWL and URS. A health provider (UK National Health Service) perspective was adopted to estimate the costs of the interventions and subsequent resource use.

Shockwave Lithotripsy Versus Ureteroscopic Treatment as Therapeutic Interventions for Stones of the Ureter (TISU): A Multicentre Randomised Controlled Non-inferiority Trial.

Background: Renal stone disease is common and can cause emergency presentation with acute pain due to ureteric colic. International guidelines have stated the need for a multicentre randomised controlled trial (RCT) to determine whether a non-invasive outpatient (shockwave lithotripsy [SWL]) or surgical (ureteroscopy [URS]) intervention should be the first-line treatment for those needing active intervention. This has implications for shaping clinical pathways.

The clinical and cost effectiveness of surgical interventions for stones in the lower pole of the kidney: the percutaneous nephrolithotomy, flexible ureterorenoscopy and extracorporeal shockwave lithotripsy for lower pole kidney stones randomised controlled trial (PUrE RCT) protocol.

Introduction: Renal stones are common, with a lifetime prevalence of 10% in adults. Global incidence is increasing due to increases in obesity and diabetes, with these patient populations being more likely to suffer renal stone disease. Flank pain from stones (renal colic) is the most common cause of emergency admission to UK urology departments.

Alpha blockers should no longer be used for ureteric stones.

Alpha-blockers have been used as medical expulsive therapy for ureteric stones for a number of years. Conventional wisdom supporting their use has recently been challenged by the publication of a large, multi-centre, randomised double-blinded, placebo-controlled study, SUSPEND, which showed that they were ineffective. This paper looks at the evidence behind the use of alpha-blockers, and discusses why we should believe the evidence we have from SUSPEND, rather than other published studies, and therefore stop using them as medical expulsive therapy.

Medical Expulsive Therapy for Ureterolithiasis: The EAU Recommendations in 2016.

Medical expulsive therapy (MET), in particular α-blockers, have been recommended as supportive medication if observational treatment of a ureteral stone was an option. Over the years, a considerable number of randomized controlled trials (RCT) as well as several meta-analyses have been published on MET, supporting the use of α-blockers. However, several recently published high quality, large, placebo-controlled randomized trials raised serious doubts about the effectiveness of α-blockers.

Tips and tricks of ureteroscopy: consensus statement. Part II. Advanced ureteroscopy.

Our "tips and tricks" focuses on all aspects of upper tract endourology and we hope these will be of use to all trainees and consultants who perform ureteroscopy. We report an "expert consensus view" from experienced endourological surgeons, on all aspects of advanced ureteroscopic techniques, with a particular focus on avoiding and getting out of trouble while performing ureteroscopy. In this paper we provide a summary of placing ureteric access sheath, flexible ureteroscopy, intra renal stone fragmentation and retrieval, maintaining visual clarity and biopsy of ureteric and pelvicalyceal tumours.

Tips and tricks of ureteroscopy: consensus statement Part I. Basic ureteroscopy.

Ureteroscopy is fast becoming the first line treatment option for the majority of urinary tract stones. Ureteroscopy training can be performed in a variety of ways including simulation, hands on ureteroscopy courses and supervised operative experience. We report an "expert consensus view" from experienced endourological surgeons, on all aspects of basic ureteroscopic techniques, with a particular focus on avoiding and getting out of trouble while performing ureteroscopy.

Use of drug therapy in the management of symptomatic ureteric stones in hospitalized adults (SUSPEND), a multicentre, placebo-controlled, randomized trial of a calcium-channel blocker (nifedipine) and an α-blocker (tamsulosin): study protocol for a randomized controlled trial.

Background: Urinary stone disease is common, with an estimated prevalence among the general population of 2% to 3%. Ureteric stones can cause severe pain and have a significant impact on quality of life, accounting for over 15,000 hospital admissions in England annually. Uncomplicated cases of smaller stones in the lower ureter are traditionally treated expectantly.

Systematic review of adrenalectomy and lymph node dissection in locally advanced renal cell carcinoma.

Context: Controversy remains over whether adrenalectomy and lymph node dissection (LND) should be performed concomitantly with radical nephrectomy (RN) for locally advanced renal cell carcinoma (RCC) cT3-T4N0M0.

Objective: To systematically review all relevant literature comparing oncologic, perioperative, and quality-of-life (QoL) outcomes for locally advanced RCC managed with RN with or without concomitant adrenalectomy or LND.

Evidence Acquisition: Relevant databases were searched up to August 2012.

Systematic review of perioperative and quality-of-life outcomes following surgical management of localised renal cancer.

Context: For the treatment of localised renal cell carcinoma (RCC), uncertainties remain over the perioperative and quality-of-life (QoL) outcomes for the many different surgical techniques and approaches of nephrectomy. Controversy also remains on whether newer minimally invasive nephron-sparing interventions offer better QoL and perioperative outcomes, and whether adrenalectomy and lymphadenectomy should be performed simultaneously with nephrectomy. These non-oncological outcomes are important because they may have a considerable impact on localised RCC treatment decision making.

Systematic review of oncological outcomes following surgical management of localised renal cancer.

Context: Renal cell carcinoma (RCC) accounts for 2-3% of adult malignancies. There remain uncertainties over the oncological outcomes for the surgical management of localised RCC.

Objective: Systematically review relevant literature comparing oncological outcomes of surgical management of localised RCC (T1-2N0M0).

Machine learning for improved pathological staging of prostate cancer: a performance comparison on a range of classifiers.

Objectives: Prediction of prostate cancer pathological stage is an essential step in a patient's pathway. It determines the treatment that will be applied further. In current practice, urologists use the pathological stage predictions provided in Partin tables to support their decisions.

Urological cancer care pathways: development and use in the context of systematic reviews and clinical practice guidelines.

Background: Making healthcare treatment decisions is a complex process involving a broad stakeholder base including patients, their families, health professionals, clinical practice guideline developers and funders of healthcare.

Methods: This paper presents a review of a methodology for the development of urological cancer care pathways (UCAN care pathways), which reflects an appreciation of this broad stakeholder base. The methods section includes an overview of the steps in the development of the UCAN care pathways and engagement with clinical content experts and patient groups.

Image-guided biopsy-diagnosed renal cell carcinoma: critical appraisal of technique and long-term follow-up.

Objectives: To critically appraise and determine the impact of image-guided biopsy on the management of indeterminate renal masses. A comparison of long-term follow-up of renal cell carcinoma (RCC) diagnosed by image-guided biopsy and radiologically obvious RCC was also carried out.

Patients And Methods: Data were collected for all the consecutive patients requiring renal core biopsies for the diagnosis of indeterminate renal masses between January 1996 and January 2006.

Endovascular control of haemorrhagic urological emergencies: an observational study.

Background: Transarterial embolisation (TAE) is an effective method in control of haemorrhage irrespective of the nature of urological emergency. As the technique and technology have evolved, it is now possible to perform highly selective embolisation. The aim of this study was to critically appraise feasibility and efficacy of therapeutic TAE in control of haemorrhagic urological emergencies using selective and non-selective embolisation.

Conjugated linoleic acid inhibits proliferation and modulates protein kinase C isoforms in human prostate cancer cells.

Prostate cancer is the second most common cancer in men. The disease etiology is poorly understood, but diet and lifestyle are contributory factors. Conjugated linoleic acids (CLAs), naturally occurring fatty acids in ruminant food products, have antitumor properties in animal models of cancer and antiproliferative effects on cancer cells in vitro.
