BACKGROUND: Predictive tables and scoring systems can predict stone clearance. However, there is a paucity of evidence regarding the prediction of complications during percutaneous nephrolithotomy (PCNL), particularly in children, which remains under-researched. To our knowledge, no studies have evaluated the risk factors for febrile urinary tract infection (FUTI) after pediatric PCNL. OBJECTIVES: To assess the predictive factors of FUTI in prepubertal children after PCNL and determine whether any prophylactic cephalosporins are superior for decreasing the FUTI rate...

Objective: To investigate the necessity of artificial kidney seeper which made through inserting a ureteral tube in the ureter to the ultrasonography-guided percutaneous nephrolithotomy (PCNL). Methods: This was a randomized prospective study. Patients who conformed to the inclusion and exclusion criteria were enrolled at Department of Urology, Frist Affiliated Hospital of Wenzhou Medical University from January 2016 to May 2017. Totally 291 patients were included in the study. Patients were randomly assigned into two groups (artificial kidney seeper group and non-artificial kidney seeper group) in different kidney seeper level (5 to <10 mm, 10 to 20 mm) respectively...

INTRODUCTION: We are a reporting on the indications, techniques, and limitations of robotic surgery in the management of renal stones disease. Robotic surgery is a good tool to manage large kidney and ureteral stones, particularly in patients with anatomic anomalies. We describe three techniques in managing staghorn kidney stones: robotic anatrophic nephrolithotomy, robotic pyelolithotomy, and robotic nephrolithotomy. MATERIAL AND METHODS: Robotic pyelolithotomy (RP) is ideal for patients with large renal pelvis and partial staghorn stone with a wide extra-renal pelvis...

BACKGROUND: To evaluate success and complication rates of endourological stone treatments and to evaluate effects of percutaneous nephrolithotomy (PCNL) on renal functions, in patients with solitary kidneys. METHODS: In our center, 3150 patients underwent PCNL between 2003 and 2017 and 142 patients underwent retrograd intrarenal surgery (RIRS) between 2013 and 2017. We retrospectively analysed the data of 82 patients with solitary kidney who underwent PCNL and of 8 patients with solitary kidney who underwent RIRS...

PURPOSE: We sought to investigate the association between renal stone composition and percutaneous nephrolithotomy outcomes in pediatric patients and define the characterization of the stone composition. METHODS: The data of 1157 children who underwent percutaneous nephrolithotomy between 1991 and 2012 were retrieved from the multicenter database of the Turkish Pediatric Urology Society. The study population comprised 359 children (160 girls, 199 boys) with stone analyses...

Life expectancy has become longer, thus the number of elderly people who require treatment for nephrolithiasis has increased. We aimed to analyze the efficacy of flexible ureterorenoscopy (f-URS) and miniaturized percutaneous nephrolithotomy (mPNL) in the management of 10 and 30 mm renal stones in patients aged >60 years. In prospective non-randomized series, the data of patients who underwent f-URS or mPNL for kidney stones between July 2013 and July 2016 were analyzed. The procedure was accepted as successful if the patient was achieved complete stone clearance according to CT imaging between 1-3 months postoperatively...

INTRODUCTION: Achieving suitable percutaneous access to the kidney is the most important step in percutaneous nephrolithotomy. The triangulation biplanar access technique under fluoroscopy is the standard method to achieve percutaneous renal access, but it is not successful in all cases. We used the new biplanar oblique access technique as a rescue method for the failed standard biplanar technique. The aim of this study was to evaluate the effects of this oblique access technique on access outcome...

OBJECTIVE: To describe the role of Duplex-Ultrasound Imaging (DUI) in prompt diagnosis of pseudoaneurysm (PSA) of a branch of the segmental renal artery (b-SRA) and evaluate outcomes of DUI directed percutaneous embolization. METHODS: Forty-five patients were referred to us for the management of intractable renal hematuria. 20 cases (44.44%) had developed PSA after nephrolithotomy. 12 cases (12.66%) had developed PSA after guided renal biopsies. 6 cases (13.33%) had developed PSA following road side trauma...

Percutaneous nephrolithotomy (PCNL) has proven very effective in the management of renal stones. However, complications are not so rare, and bleeding is one of the most worrisome; it has a reported incidence of 1%-3% and may happen during track dilatation. In addition, arterial pseudoaneurysms and/or arteriovenous fistulas (AVF) may occur. We report the case of a patient with an intrarenal pseudoaneurysm associated with an AVF, after PCNL. Superselective endovascular embolization with Onyx® was successfully performed, achieving exclusion of the pseudoaneurysm and AVF with preservation of the remaining vascularization of the kidney...

INTRODUCTION: To make percutaneous access easier in PCNL, we developed Automated Needle Targeting with X-ray (ANT-X) Method: ANT-X uses an image registration software with a closed loop feedback system to autoalign the puncture needle to the desired calyx using the bullseye technique. We tried percutaneous punctures on a live pig model and compared the results with free-hand technique. We then performed our first PCNL in a human subject with the aid of ANT-X. Our patient was a 48 year-old gentleman with a 1...

Objective The objective of this meta-analysis was to compare the efficacy and safety of externalized ureteral catheter (EUC) and double-J stent (DJS) in tubeless percutaneous nephrolithotomy (PCNL) for patients with upper urinary stones based on published literature. Materials and Methods A comprehensive literature search using Pubmed, Embase, and Cochrane Library was performed to find studies comparing outcomes of EUC and DJS for treating patients with upper urinary stones up to Dec 2017. 7 studies, which included 863 patients from 5 randomized controlled trials(RCTs) and 2 non-RCTs published between 2009 and 2017, met our inclusion criteria and were included in this systematic review and meta-analysis...

BACKGROUND: the optimal management of lower calyceal stones is still controversial, because no single method is suitable for the removal of all lower calyceal stones. Minimally invasive procedures such as extracorporeal shock wave lithotripsy (ESWL), percutaneous nephrolithotomy (PCNL) and flexible ureteroscopy (fURS) are the therapeutic methods for lower calyceal stones. The aim of this study was to identify the optimal management of 10-20 mm lower pole stones. METHODS: a meta-analysis of cohort studies published before July 2016 was performed from Medline and Cochrane databases...

INTRODUCTION: Single institution studies suggest a benefit of a week of preoperative antibiotics prior to percutaneous nephrolithotomy (PCNL). These studies are limited by lower quality methodology such as the inclusion of heterogeneous populations or the use of non-standard definitions of sepsis. The American Urological Association (AUA) Best Practice Statement recommends <24 hours of IV antibiotics, but no other data exist about the duration/benefit of preoperative antibiotics. We sought to perform a rigorous (using CONSORT guidelines), multi-institutional trial to assess preoperative antibiotics in PCNL patients at low risk of developing infections...
