PURPOSE The aim of this study was to evaluate the efficacy and safety of retrograde intrarenal surgery (RIRS) for the treatment of renal stones and to analyze the predictive factors for stone-free. MATERIALS AND METHODS We retrospectively reviewed the records of patients who underwent RIRS for renal stones from January 2000 to July 2009. We identified 66 RIRSs (63 patients with 3 bilateral re...

BACKGROUND It can be assumed that stones in the urinary tract continuously increase in size by incorporating material from urine. Consequently, urine will exhibit depleted concentrations of lithogenic constituents when urinary stones are present in the patient's urinary tract. METHODS To calculate the influence of the depletion effect, we considered two different models of stone growth. In th...

This issue of the AJU deals with stone disease, but perhaps not in the way you know it. Currently stone disease is recognised as a systemic and recurrent disease linked to many other socalled ‘civilisation’ diseases. Therefore the traditional surgical approach of ‘break it’, ‘forget it’ and ‘wait until it comes back’ is slightly outdated. Of course, surgical advances in minimally invasive techn...

This paper discusses one of the issues that are not covered by current stepping stone detection based researches. Although dropped packet problems are well-known problem in real network environment, all of the stepping stone detection researches just assume that dropped packet problems do not occur. Stepping stone detection research already in complex condition where each enhancement of the res...

INTRODUCTION Kidney stones are a common problem worldwide with substantial morbidities and economic costs. Medical therapy reduces stone recurrence significantly. Much progress has been made in the last several decades in improving therapy of stone disease. AREAS COVERED This review discusses i) the effect of medical expulsive therapy on spontaneous stone passage, ii) pharmacotherapy in the p...

iii Natural disturbances are an integral part of the processes shaping and maintaining the forested landscapes in British Columbia. Understanding the historic variability in the frequency, intensity/severity, size, and duration of natural disturbances is important for guiding sustainable forest management and projecting the effects of natural disturbances on habitat and timber supply. This repo...
