OBJECTIVES: To assess whether horizontal versus vertical bolster orientation affects kidney position during prone percutaneous nephrolithotomy as this could impact the need for supracostal access and therefore the likelihood of pleural injury. METHODS: In a prospective trial, ten subjects with 20 renal units underwent magnetic resonance imaging in prone position with standard cylindrical bolsters oriented vertically and then horizontally. Vertical bolsters were placed along the lateral aspect of the chest...

BACKGROUND: Percutaneous nephrolitotomy (PCNL) is the preferred treatment for large renal stones. There is a need for more comparative data for different lithotripters used in PCNL. OBJECTIVE: To evaluate the comparative safety and efficacy of ultrasonic and pneumatic lithotripsy in patients undergoing PCNL. DESIGN, SETTING, AND PARTICIPANTS: This randomized clinical trial was conducted at Labbafinejad University Hospital, Tehran, Iran. A total of 180 patients were selected and divided randomly into two groups: 88 patients to pneumatic and 92 to ultrasonic lithotripsy...

CONTEXT: In an effort to reduce morbidity related to percutaneous nephrolithotomy (PCNL), some investigators have progressively introduced miniaturised approaches. The development of miniaturised nephroscopes facilitated widespread dissemination of these techniques and a significant expansion of the role of PCNL in endourology. OBJECTIVE: To discuss the different techniques comprising modern PCNL and identify the pros and cons of each of them. EVIDENCE ACQUISITION: Data for this review were identified through a search of PubMed, including studies published in the last 20 yr in core clinical journals in English...

The purpose of this study is to determine the perioperative risk factors for increased blood loss in children undergoing percutaneous nephrolithotomy (PCNL).We retrospectively reviewed the data on pediatric patients who had undergone PCNL for stone disease in our department. Blood loss estimation was quantified by measuring the changes in hematocrit plus the volume of red blood cells transfused. Univariate and multivariate linear regression analyses were performed to evaluate risk factors associated with increased blood loss after pediatric PCNL...

INTRODUCTION: With advancements in endoscopic surgery, open surgical techniques for urinary system stones have paved the way for the application of less invasive treatment modalities in patients with pediatric kidney stone disease. These treatment options include extracorporeal shock wave lithotripsy (ESWL), percutaneous nephrolithotomy (PCNL), and retrograde intrarenal surgery (RIRS). OBJECTIVE: We aimed to compare the efficacy and safety of RIRS and micro-PCNL techniques in the surgical treatment of kidney stones in pediatric patients...

BACKGROUND: Percutaneous nephrolithotomy (PCNL) is performed to treat relatively large renal stones. Recent publications indicate that tubeless and total tubeless (stentless) PCNL is safe in selected patients. We performed a systematic review and network meta-analysis to evaluate the feasibility and safety of different PCNL procedures, including total tubeless, tubeless with stent, small-bore tube, and large-bore tube PCNLs. METHODS: PubMed, Cochrane Central Register of Controlled Trials, and EMBASE™ databases were searched to identify randomized controlled trials published before December 30, 2013...

INTRODUCTION: Ureterocalicostomy (UC) is a well-established treatment option for patients with recurrent ureteropelvic junction obstruction (UPJO) with postoperative fibrosis and a relatively inaccessible renal pelvis. This study aimed to evaluate the long-term outcome of UC and factors predicting its failure. MATERIALS AND METHODS: We retrospectively analysed data of 72 patients who underwent open or laparoscopic UC from 2000 to 2014. Variables that may affect the outcomes of UC were assessed with regard to primary pathology, age, serum creatinine, preoperative renal size (<15 cm and > 15 cm), renal cortical thickness (<5mm and >5 mm), grade of hydronephrosis and preoperative renal function (GFR < or >20 ml/min)...

We analyzed our stone-free rates of PNL with regard to stone burden and its ratio to the renal collecting system volume. Data of 164 patients who underwent PNL were analyzed retrospectively. Volume segmentation of renal collecting system and stones were done using 3D segmentation software with the images obtained from CT data. Analyzed stone volume (ASV) and renal collecting system volume (RCSV) were measured and the ASV-to-RCSV ratio was calculated after the creation of a 3D surface volume rendering of renal stones and the collecting system...

OBJECTIVES: To investigate the anatomical relations of the papillary, infundibular and pelvic approach to percutaneous nephrolithotomy (PCNL) and evaluate the amount of vascularization at the respective sites. MATERIALS: (99m)Tc-dimercaptosuccinic acid SPECT/CT renal scintigraphies or Computerized tomographies perfusion (CTP) were performed in 40 patients (prone n=20 or supine position n=20).

BACKGROUND: Intravenous misplacement of a nephrostomy tube after percutaneous nephrostolithotomy (PCNL) is very rare in clinical experiences. This report summarizes the characteristics and management of intravenous misplacement. CASE PRESENTATION: We present two uncommon cases of intravenous nephrostomy catheter misplacement after PCNL from among 4220 patients who underwent PCNL between January 2009 and December 2015. The tip of the tube was located in the inferior vena cava in one case and in the renal vein in the other...

This study aimed to assess the role of pre-designed route on computer tomography urography (CTU) in the ultrasound-guided percutaneous nephrolithotomy (PCNL) for renal calculus.From August 2013 to May 2016, a total of 100 patients diagnosed with complex renal calculus in our hospital were randomly divided into CTU group and control group (without CTU assistance). CTU was used to design a rational route for puncturing in CTU group. Ultrasound was used in both groups to establish a working trace in the operation areas...

OBJECTIVES: Mini-PCNL is a potentially less invasive technique than standard percutaneous nephrolithotomy (PCNL). We present our experience and results comparing both approaches in large burden complex renal calculi. METHODS: Prospective non randomized study comparing PCNL (24/26F nephroscope; Group A) and Mini-PCNL (15/18F; Group B) perioperative and postoperative results, in 40 (20 each group) consecutive patients between 2013 and 2014. We analyze demographic data, hemoglobin drop, urine culture, stone characteristics, operative time, puncture, number and size of the tract, disintegration energy sources, nephrostomy placement, hospital stay, stone free rate and Clavien-Dindo complications...

The purpose of the study was to present our experience of retaining encrusted ureteral stents (EUS) and discuss the effectiveness of 4.5/6.5F ureteroscope (URS) in the procedure. The data of patients with EUS in our center from January 2012 to December 2016 were retrospectively analyzed. The inclusion criterion was ureteral stents that required intervention above the ureteral orifice to retain and was proved to be encrusted. Impacted stents would be removed by ureteroscope lithotripsy (URL) via 8/9.8F or 4...

OBJECTIVES: To provide a systematic review and meta-analysis of studies comparing ureterolithotripsy (URS) with percutaneous nephrolithotripsy (PCNL) or laparoscopic ureterolithotomy (LU) techniques for the management of large proximal ureteral stones (diameter greater than 10 mm). METHODS: A literature search was performed using PubMed, EMBASE, EBSCO, Web of Science, and Cochrane Library to identify suitable studies until November 2016.

Percutaneous nephrolithotomy (PCNL) is a commonly used type of minimally invasive treatment in kidney stone surgeries. Surgical success is assessed according to residual stone amount after surgery. The purpose of this study is to compare the two methods' success and practicality that are applied after the fracture of the stone in the patients who applied PCNL and which enable the removal of the residual stones. Among 102 patients who underwent a single-session of PCNL at our department between June 2015 and November 2016 were evaluated...
