Percutaneous nephrolithotomy (PCNL) is the regular surgery for treating large or complex renal stones. Since its first inception, many variations have come in the approach including the modifications of patient position. The prone position is traditionally used, and subsequently, variations in prone and supine technique have been proposed and assessed over time. In an attempt to provide comprehensive information about the strategy applications of patient's position, the present review describes the position-related general basis, and provides a literature review of the pros and cons of various positions from a surgical and anaesthetic point of view...

Percutaneous nephrolithotomy (PCNL) is currently the treatment of choice for large and complex renal calculi. One of the main advantages of PCNL is gaining a real stone-free status in a single session. However, there are several major complications that necessitate careful patient selection for this surgery (1). In this well written manuscript the authors deal with the true rates and importance of residual fragments following PCNL surgeries done in a high volume center. They reviewed 658 PCNL procedures from 2008-2013 that underwent a CT scan on post-operative day one...

Neutrophil to lymphocyte ratio (NLR), derived neutrophil to lymphocyte ratio (dNLR), platelet to lymphocyte ratio (PLR) and lymphocyte to monocyte ratio (LMR) were promising biomarkers used to predict diagnosis and prognosis in various inflammatory responses diseases and cancers. However, there have been no reports regarding these biomarkers in kidney stone patients. This study aimed to evaluate the predictive value of inflammatory biomarkers for metabolic syndrome (MetS) and post-PCNL SIRS in nephrolithiasis patients...

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...

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...

PURPOSE: Aspirin is often stopped prior to percutaneous nephrolithotomy over concern for surgical bleeding risk. There is evidence that discontinuing ASA perioperatively increases thromboembolic events and that continuing it may be safe. We sought to assess the effect of low-dose ASA continuation through PCNL and its effect on surgical and safety outcomes. MATERIALS AND METHODS: We retrospectively reviewed 285 consecutive PCNLs between 2012-2015 at our institution...

INTRODUCTION AND OBJECTIVES: The restriction of resident hours with an increasing focus on patient safety and a reduced caseload has impacted surgical training. A complex and complication prone procedure such as percutaneous nephrolithotomy (PCNL) with a steep learning curve may create an unsafe environment for hands-on resident training. In this study, we validate a high fidelity, inanimate PCNL model within a full immersion simulation environment. METHODS: Anatomically correct models of the human pelvicalyceal system (PCS), kidney, and relevant adjacent structures were created using poly-vinyl alcohol (PVA) hydrogels and 3D-printed injection molds...

INTRODUCTION: The management of residual fragments (RFs) that persist after percutaneous nephrolithotomy (PCNL) has been poorly studied. Fragments have the potential to grow or cause symptoms. The aim of this study was to follow patients with fragments after PCNL to identify predictors of stone-related events (re-interventions and complications) after PCNL. PATIENTS AND METHODS: Data were retrospectively collected from patients who underwent surgery from 2008 to 2013 at our hospital...

INTRODUCTION: A precise puncture of the renal collecting system is the most essential step for percutaneous nephrolithotomy (PCNL). There are many techniques describing this crucial first step in PCNL including the bull's eye technique, triangulation technique, free-hand technique, and gradual descensus technique. We describe a novel puncture guide to assist accurate percutaneous needle placement during bull's eye technique. METHODS: The mini access guide (MAG) stabilizes the initial puncture needle by mounting it on an adjustable multidirectional carrier fixed to the patient's skin, which aids in achieving the "bull's eye" puncture...
