OBJECTIVE: Percutaneous nephrolithotomy is a well-established procedure for the management of urinary calculi and can be performed intercostally or subcostally. Favoring one approach versus the other is still debatable and literature has been inconclusive regarding the efficacy and safety of both approaches. Hence, this study aims to assess the safety and efficacy of direct non-angled intercostal technique performed under full expiration and to compare it to the subcostal approach. METHODS: PCNL was conducted among 361 patients during 2010-2015 at Saint George Hospital University Medical Center in Beirut, Lebanon...

While the effects of percutaneous nephrolithotomy (PCNL) on patients with normal functioning kidneys have been widely studied, the outcomes of PCNL in populations with renal insufficiency remains under reported. We aimed to examine the literature and evaluate the efficacy and safety of PCNL in this non-indexed patient group. A systematic search was performed in accordance with Cochrane guidelines. This served to identify original studies investigating PCNL carried out in the adult population with chronic kidney disease published over the past 20 years (since 1997)...

BACKGROUND: The aim of this study is the caparison of the complications rate among the patients which underwent nephrostomy removal with and without performing nephrostography. MATERIALS AND METHODS: Between October 2010 and November 2011, 200 patients who underwent standard percutaneous nephrolithotomy (PCNL) procedures were included in this study. The patients were randomly assigned into two groups, Group A (n = 100) did not undergo the antegrade nephrostography on postoperative day 2 and the patients were discharged keeping the nephrostomy until postoperative day 3, while in Group B (n = 100) the nephrostomy tube was removed on postoperative day 3 after antegrade nephrostography demonstrating ureteral drainage down to the bladder...

OBJECTIVE: The objective of this study is to evaluate our methods for management of renal caliceal diverticular stones (CDS). MATERIALS AND METHODS: We conducted a retrospective study from January 2005 to July 2015 and included patients who were treated for renal CDS. Patients were evaluated for treatment modality, puncture site (in case percutaneous nephrolithotomy [PCNL] attempted), operative time, stone clearance rate, and complications. During PCNL, if the infundibulum was found to connect the diverticulum to the calyx, then a double J stent was placed...

Introduction Management of paediatric stone disease is challenging, with standard PCNL having a good stone free rate (SFR) but with associated high complication rates. Miniaturisation of this technique has led to the rise of minimally invasive PCNL techniques such as micro (<10Fr) and ultra-mini (<15Fr) PCNL procedures. Our objective was to perform a systematic review of the literature in order to evaluate the success and complication rates of minimally invasive PCNL techniques in the paediatric age group (<18 years)...

Background: A rare percutaneous nephrolithotomy (PCNL) complication and its management is reported. Case Presentation: A male patient, 43 years of age, underwent PCNL for a large left pyelocaliceal stone. Surgery was performed in the Valdivia-Galdakao supine position. The percutaneous tract was established by combined radiologic and sonographic guidance. The tract was dilated by balloon and a 24F Amplatz sheath was located. As complete clearance was not achieved because of a residual lower pole caliceal stone, a ureteral Double-J and a 20F nephrostomy were located for a second-look PCNL through the same tract after 7 days...

INTRODUCTION: Miniaturization of instruments has changed the paradigms of percutaneous nephrolithotomy (PCNL). To date, however, few studies have analyzed the possible renal trauma generated by PCNL tract dilation. The purpose of this study is to evaluate and compare systematically the renal injury of all PNCL dilation techniques in pork kidneys (PK) and cadaveric kidney models (CK). MATERIAL AND METHODS: Twelve dilation devices were tested (from 4.8 to 30 French (Fr)) including micro- and mini- PCNL kits, the Alken dilation set, 20 and 30 ATM balloons and the Amplatz set...

INTRODUCTION: Supine percutaneous nephrolithotomy (PCNL) has become increasingly widespread during the last 2 decades. The aim of this study was to analyze the transition from prone to mainly supine PCNL in 2 endourologic centers. MATERIAL AND METHODS: We retrospectively analyzed data on 214 consecutive supine PCNLs divided into the first (2011-2013) and last (2014-2016) 3 years of this study. The first 27 cases were also included in a randomized controlled trial (RCT) by comparison with 24 prone PCNLs...

INTRODUCTION AND OBJECTIVES: Although extracorporeal shock wave lithotripsy (ESWL) is the first choice for pediatric renal calculi <2 cm, the success rate after the first session is low. This is in contrast to other minimally invasive procedures like percutanous nephrolithotomy (PCNL) and retrograde intrarenal surgery (RIRS), which have higher rates of success. Therefore, the present study sought to identify predictors of success after one session of ESWL. PATIENTS AND METHODS: A prospective study including 100 children with renal stone burden <2 cm who underwent ESWL at the present institution...

INTRODUCTION: Interventional radiologist may be hesitant to obtain upper pole access for percutaneous nephrolithotomy (PCNL) due to a higher complication rate. Renal access gained by urologists may achieve higher stone-free rates with similar complication rates. We evaluate our institution's contemporary results of percutaneous renal access in the upper pole for nephrolithotomy by urologists, which we believe both safe and efficacious. MATERIALS AND METHODS: This retrospective chart review included all PCNL's performed by fellowship-trained endourologists from 2003 to 2014 at a single institution...

INTRODUCTION: The feasibility and safety of supracostal punctures in supine percutaneous nephrolithotomy (PCNL) are still controversial. In this study we aim to compare success and complication rates from prone and supine PCNL with at least one supracostal puncture. MATERIAL AND METHODS: We reviewed our electronic database for all supracostal PCNLs performed in our institution from February 2008 to September 2013. Patients were enrolled in the study if at least one supracostal puncture was required during surgery...
