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...

OBJECTIVE: The aim of the present anatomic and radiologic study was to evaluate the location, extension and characteristics of the Brödel's plane and eventually define its different patterns. MATERIAL AND METHODS: We evaluated 15 human normal kidneys sampled from un-embalmed cadavers without clinical history or anatomical evidence of renal diseases. Kidneys with the surrounding perirenal fat tissue were removed en bloc with the abdominal segment of the aorta. The renal artery was injected with acrylic and radiopaque resins...

Percutaneous nephrolithotomy is a common surgical treatment for large and complex stones within the intrarenal collecting system. A wide variety of complications can result from this procedure, including bleeding, injury to surrounding structures, infection, positioning-related injuries, thromboembolic disease, and even death. Knowledge of the different types of complications can be useful in order to prevent, diagnose, and treat these problems if they occur. This review describes the diversity of complications with the goal of improving their avoidance and treatment...

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...

In this study we have characterised the learning curve for percutaneous nephrolithotomy procedures over 301 cases for six years. Different surrogate parameters of clinical expertise have been used, such as dose area product, total procedure time, fluoroscopy time and personal equivalent doses. In addition, two different endourologists have been monitored; one of whom had specific Radiation Protection training (ICRP 85). Eye lens dose was estimated from thermoluminescent dosimeters. Significant differences were observed between both endourologists, especially in the fluoroscopy time...

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...

BACKGROUND: To update a previously published systematic review and meta-analysis on the efficacy and safety of tubeless percutaneous nephrolithotomy (PCNL). METHODS: A systematic literature search of EMBASE, PubMed, Web of Science, and the Cochrane Library was performed to confirm relevant studies. The scientific literature was screened in accordance with the predetermined inclusion and exclusion criteria. After quality assessment and data extraction from the eligible studies, a meta-analysis was conducted using Stata SE 12...

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"...

PURPOSE: To present our experience of combined single-percutaneous tract minimally invasive percutaneous nephrolithotomy (MPCNL) and flexible ureteroscopic lithotripsy (FURL) in managing staghorn calculi (SC) in oblique supine lithotomy position and to define the safety, efficiency, and feasibility of this approach. PATIENTS AND METHODS: Eighty-seven patients with SC treated with surgery in our hospital from March 2014 to January 2016 were retrospectively analyzed...

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...

PURPOSE: Ultrasound-guided PCNL in Galdakao-modified supine Valdivia (GMSV) position has taken into consideration during the last decade; however, guidewire slippage during tract dilatation is still a big concern in this approach. Here we presented our results of combination of this modification with ureteroscopic guidewire retrieval to ensure a safe and confident renal access. MATERIALS AND METHODS: From June 2015 to March 2016, 30 consecutive patients with renal stone of ? 2...

PURPOSE: Urolithiasis during pregnancy poses risks for mother and the fetus with specific challenges in diagnosis and management. We report our experience with urgent percutaneous nephrolithotomy (PCNL) in seven pregnant patients with symptomatic renal stone in early pregnancy. MATERIALS AND METHODS: Seven pregnant patients with symptomatic renal stones were reviewed. The technique comprised PCNL with complete access under guide of ultrasonography in prone position under general anesthesiausing pneumatic lithoclast for stone fragmentation...

Background: Splenic urinoma has not been previously reported as a complication of percutaneous nephrolithotomy (PNL). Case Presentation: A 46-year-old Caucasian male underwent PNL for two large left renal stones. Surgery was performed in prone split-leg position, with access obtained through combined fluoroscopic guidance and direct ureteroscopic observation of the targeted calix. The tract was dilated to 30F using a pressure balloon, and complete clearance of stones was obtained through a combination of rigid and flexible nephroscopy, as well as antegrade ureteroscopy...

OBJECTIVE: To describe the use of renal angiography in the detection of renal vascular injuries following percutaneous nephrolithotomy and to assess the efficacy of endovascular management of these complications. MATERIALS AND METHODS: This was a retrospective review of 159 consecutive patients over a period of 12 years from 2005 to 2016 who presented with significant post nephrolithotomy hemorrhage and who were evaluated by renal angiography as a first-line diagnostic study, followed by embolization of identified renal vascular injuries in the same session...

INTRODUCTION: Little information is available concerning the radiation exposure of anesthesiologists, and no such data have previously been collected in Iran. This prospective study was performed to determine the amount of radiation exposure of anesthesiologists for the purpose of assessing whether or not dangerous levels of radiation exposures were being reached, and to identify factors that correlate with excessive risk. PARTICIPANTS AND METHODS: The radiation exposure of all anesthesiology residents and the attending of Shiraz University of Medical Sciences during a 3-month period (from June to August 2016) was measured using a film badge with monthly readings...
