Hepatolithiasis is the presence of calculi within the intrahepatic bile duct specifically located proximal to the confluence of the left and right hepatic ducts. The ultimate goal of hepatolithiasis treatment is the complete removal of the stone, the correction of the associated strictures and the prevention of recurrent cholangitis. Although hepatectomy could effectively achieve the above goals, it can be restricted by the risk of insufficient residual liver volume, and has a 15.6% rate of residual hepatolithiasis...

BACKGROUND: Computed Tomography (CT) is considered the gold-standard for the pre-operative evaluation of urolithiasis. However, no Hounsfield (HU) variable capable of differentiating stone types has been clearly identified. The aim of this study is to assess the predictive value of HU parameters on CT for determining stone composition and outcomes in percutaneous nephrolithotomy (PCNL). METHODS: Seventy seven consecutive cases of PCNL between 2011 and 2016 were divided into 4 groups: 40 (52%) calcium, 26 (34%) uric acid, 5 (6%) struvite and 6 (8%) cystine stones...

BACKGROUND: It remains controversial as to whether active stone removal should be performed in patients with poor performance status because of their short life expectancy and perioperative risks. Our objectives were to evaluate treatment outcomes of active stone removal in patients with poor performance status and to compare life prognosis with those managed conservatively. METHODS: We retrospectively reviewed 74 patients with Eastern Cooperative Oncology Group performance status 3 or 4 treated for upper urinary tract calculi at our four hospitals between January 2009 and March 2016...

INTRODUCTION: Reducing the percutaneous nephrolithotomy (PCNL) tract size reduces the morbidity associated with the procedure. Prolonged procedure time is a concern. Modification in technique required is to fragment the stone into smaller particles and remove them using the vacuum cleaner effect. This prospective study compares the efficacy and morbidity of reducing the tract size from the standard 24-16.5 Fr for stones sized from 16 to 30 mm. METHODS: 123 patients were enrolled in this prospective study and distributed into 2 groups based on the tract size used (group A 16...

We describe our 'Tips and tricks' of ureteroscopy and lasertripsy (URSL) for paediatric ureteric calculi. All regional referrals directed to the paediatric urologist are discussed in a formal stone multidisciplinary team (MDT) meeting with urologists, radiologists, and biochemical pathologist. A paediatric urologist (SG) and an experienced adult endourologist (BS) do these stone procedures jointly as a twin-surgeon team approach for each patient.

INTRODUCTION: Percutaneous nephrolithotomy (PNL) is the treatment of choice for larger and complex renal calculi. First step in performing PNL is to obtain access to the renal cavity using either fluoroscopy or ultrasound (US) guidance or a combination of both. Which guiding method to choose is controversial? A systematic review of the literature was performed comparing image guidance modalities for obtaining access in PNL. Evidence acquisition and synthesis: A PubMed, Scopus and Cochrane search for peer-reviewed studies was performed using the keywords "ultrasound" AND "fluoroscopy" AND "Percutaneous nephrolithotomy"...

Background: Drainage of any deep seated abscess often requires placement of catheters along with other conservative measures. These catheters are removed when the drainage volume reduces to clinically insignificant levels. However, if left in situ, there are potential complications. One such complication necessitating additional surgical procedure is highlighted in this case report. Malecot's catheter and children may be more at risk for such a complication. Case Presentation: A 7-year-old girl presented with recurrent episodes of right flank pain associated with high-grade fever with chills for the last 5 months and right perinephric drain in situ...

REVIEW
Gerry K Schwalfenberg, Stephen J Genuis
The scientific literature provides extensive evidence of widespread magnesium deficiency and the potential need for magnesium repletion in diverse medical conditions. Magnesium is an essential element required as a cofactor for over 300 enzymatic reactions and is thus necessary for the biochemical functioning of numerous metabolic pathways. Inadequate magnesium status may impair biochemical processes dependent on sufficiency of this element. Emerging evidence confirms that nearly two-thirds of the population in the western world is not achieving the recommended daily allowance for magnesium, a deficiency problem contributing to various health conditions...
