BACKGROUND AND PURPOSE Flexible ureterorenoscopic holmium laser lithotripsy allows retrograde management of renal calculi that previously needed alternative strategies. This study assesses the influences of stone size, density, and location on treatment outcomes from a large series. PATIENTS AND METHODS Data concerning patients who presented for(More)
OBJECTIVE To describe a protocol for transperineal sector biopsies (TPSB) of the prostate and present the clinical experience of this technique in a UK population. PATIENTS AND METHODS A retrospective review of a single-centre experience of TPSB approach was undertaken that preferentially, but not exclusively, targeted the peripheral zone of the prostate(More)
PURPOSE A permanent prostate brachytherapy (PPB) program utilizing intraoperative inverse-planned dynamic dose-feedback was initiated without prior firsthand experience of alternative techniques. The purpose of this study is to assess the dosimetric learning curve associated with this approach. METHODS AND MATERIALS A total of 77 patients underwent PPB(More)
OBJECTIVES To determine the sensitivity and specificity of multiparametric magnetic resonance imaging (mpMRI) for significant prostate cancer with transperineal sector biopsy (TPSB) as the reference standard. PATIENTS AND METHODS The study included consecutive patients who presented for TPSB between July 2012 and November 2013 after mpMRI (T2- and(More)
AIMS Iron-deficiency anaemia (IDA) is a recognized complication of colorectal cancer (CRC) especially with right-sided tumours, and failure to investigate the anaemia in older patients may lead to a delay in diagnosis. The aims of this study were to establish the proportion of patients with CRC shown to have an IDA for more than six months before diagnosis(More)
BACKGROUND AND PURPOSE Knowledge of the ureteral response to instrumentation is limited. Ureterodynamic parameters such as intraureteral pressure, conduction velocity, direction of peristalsis, and electromyography have been measured using a variety of methods; however, these techniques are impractical for routine clinical use. The aim of this study was to(More)
PURPOSE To present a method for the dosimetric analysis of permanent prostate brachytherapy implants using a combination of stereoscopic X-ray radiography and magnetic resonance (MR) imaging (XMR) in an XMR facility, and to compare the clinical results between XMR- and computed tomography (CT)-based dosimetry. METHODS AND MATERIALS Patients who had(More)
PURPOSE To summarise the practical aspects of the development of techniques of interstitial permanent prostate brachytherapy (PPB) implantation. Prostate brachytherapy dates back to Pasteau's publication in 1913 describing the insertion of a radium capsule into the prostatic urethra to treat carcinoma of the prostate. Various implantation methods were(More)
