Background: At present, the percutaneous nephrolithotripsy (PCNL) is performed both in supine and in prone position. The aim of this paper is to describe an innovative position during PCNL. Methods: We describe a supine position. The patient's legs are slightly abducted at the hips. The thorax is laterally tilted (inclination 30°-35°) and kept in the right position by one or two gel pads placed between the scapula and the vertebrae. External genitalia can be accessed at any time, so that it is always possible to use flexible instruments in the upper urinary tract...

INTRODUCTION: Currently, there is a paucity of data evaluating the outcomes of supine percutaneous nephrolithotomy (PCNL) in septuagenarian and octogenarian patients. In this study we aim to compare the outcomes of supine PCNL in elderly patients with those of younger population. MATERIAL AND METHODS: A matched case-control study was performed from January 2009 through December 2015 using our prospectively collected kidney stone database. Case group was composed of patients with age greater than 70 years...

A 29-year-old patient with normal preanesthetic evaluation was planned for percutaneous nephrolithotomy (PCNL) for right nephrolithiasis with right pyelolithiasis. Surgery was performed under general anesthesia with endotracheal intubation with muscle relaxation. At the conclusion of surgery, when the patient was turned over to supine position, tense abdomen was noted. Immediately extended focused assessment with sonography in trauma (eFAST) was done in which both right and left quadrants of abdomen including pericardial and suprapubic region, right and left thoracic, and both lung basis were examined...

OBJECTIVE: To compare the distance between the colon and the trajectory of percutaneous nephrolithotomy (PCNL) access both in prone and flank-free modified supine (FFMS) positions as measured on computed tomography and to study the effect of age, gender, BMI, side, and previous renal surgery as influencing factors. PATIENTS AND METHODS: In this prospective study, we included 367 patients scheduled for PCNL. All patients underwent low dose abdominal computed tomography both in prone and FFMS positions...

Introduction: Percutaneous nephrolithotomy (PCNL) is traditionally performed with the patient in the prone position for large renal calculi. However, anesthetic limitations exist with the prone position. Similarly, the supine position is associated with poorer ergonomics due to the awkward downward position of the renal tract, a smaller window for percutaneous puncture, and a higher risk of anterior calyx puncture. This study aimed to demonstrate the feasibility and safety of lateral-PCNL in managing large renal calculi without the disadvantages of prone and supine positions...

INTRODUCTION: To assess the outcome of same-session bilateral tubeless percutaneous nephrolithotomy (BPCNL) in supine and prone positions and to compare them to unilateral tubeless PCNL (UPCNL). MATERIALS AND METHODS: Consecutive PCNL patients treated at two institutions between 2006-2016 were analyzed. Tubeless BPCNL was performed when indicated. RESULTS: Fifty-eight patients underwent BPCNLs [30 supine (SBPCNL) and 28 prone (PBPCNL)], while 1395 patients underwent UPCNLs...

Objective: This study compared the stone opacity effect in patients who had radiopaque and radiolucent stones in percutaneous nephrolithotomy (PCNL) results. Material and methods: The medical records of 171 complete supine PCNL procedures were gathered. Patients were categorized into two groups: those with radiopaque (n=141) and those with radiolucent (n=30) stones. Kidney, ureter and bladder x-ray was done a day after PCNL and Ultrasound imaging was done two weeks later to evaluate the stone free rate...

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...

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...

BACKGROUND: The aim of this study was to report current practices of percutaneous nephrolithotomy (PCNL) among endourologists. METHODS: An internet survey was administered to Endourological Society members. Responders were distributed into three groups according to the number of PCNL cases per year (<50, 50-100, >100). PCNL technical details as well as opinions regarding specific clinical case scenarios were evaluated and compared between groups. RESULTS: We received 300 responses from 47 different countries...

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...

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: 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...
