INTRODUCTION The management of ultrasound (US) detected gallbladder (GB) polyps remains a dilemma. The aim of this study was to assess the size distribution and the outcome of US follow-up of GB polyps. MATERIAL AND METHODS The study was approved by the Danish Data Protection Agency. US reports from patients examined with abdominal US in our department(More)
OBJECTIVE. The purpose of this study was to assess the diagnostic accuracy of strain and shear-wave elastography for determining targets of varying stiffness in a phantom. The effect of target diameter on elastographic assessments and the effect of depth on shear-wave velocity were also investigated. MATERIALS AND METHODS. We examined 20 targets of varying(More)
OBJECTIVE To examine the effect of ureteral access sheath (UAS) on the expression of the pro-inflammatory mediators cyclooxygenase-2 (COX-2) and tumor necrosis factor-α (TNF-α) in the ureteral wall. MATERIAL AND METHODS In 22 pigs an UAS was inserted and removed after 2 minutes on one side and 2 hours on the contralateral side. Postoperatively ureters(More)
BACKGROUND Ultrasonography of the testis is a well-established diagnostic tool in detection of testicular microlithiasis (TML). Operator-dependent diagnostic variation related to skill, knowledge, and operator consistency are factors that influence detection of TML. PURPOSE To determine inter- and intraobserver agreement for detection of TML using(More)
Introduction: We present a retrospective 2-year follow-up cohort of 103 men with testicular microlithiasis (TML) and discuss patient compliance and the value of surveillance. Methods: A retrospective analysis of patients examined with scrotal ultrasonography (US) in the period from 2008 through 2010 was performed. A total of 103 men with TML were diagnosed(More)
To perform a systematic literature review to assess whether the occurrence of testicular microlithiasis (TML) in conjunction with other risk factors is associated with testicular cancer. A systematic literature search was performed of original articles in English published 1998 to 2015. Relevant studies were selected by reading the title and abstract by two(More)
BACKGROUND Elastography of the testis can be used as a part of multiparametric examination of the scrotum. PURPOSE To determine the testicular stiffness using acoustic radiation force impulse imaging (ARFI) technique in men with testicular microlithiasis (TML). MATERIAL AND METHODS In 2013, 12 patients with diagnosed testicular microlithiasis in 2008(More)
To correlate ureteral lesions visualized during ureteroscopy with histopathological findings. Ureteral access sheaths (UAS) sized 13/15 Fr. were inserted bilaterally in 22 laboratory pigs. During retraction of the UAS with a semirigid ureteroscope inside, ureteral lesions were evaluated and registered using the Post-ureteroscopic lesion scale (PULS).(More)
Objective. High intraluminal pressure during ureterorenoscopy (URS) increases risk of infectious and haemorrhagic complications. Intrarenal pressure may be reduced by the use of ureteral access sheaths (UASs), which on the other hand may cause ureteral damage. We have previously shown that the β-agonist isoproterenol (ISO), when administered topically in(More)
INTRODUCTION The widespread use of computed tomography (CT) improves detection of pulmonary lesions, which are not only detected at an increased rate but also at a smaller size. CT-guided lung biopsies are now more frequently used than fluoroscopy-guided lung biopsies. The main aim of the present paper was to investigate the outcome and complications of the(More)
