OBJECTIVE: Kidney puncture during percutaneous nephrolithotomy (PCNL) is regarded as one of the most demanding aspects of the procedure and only a minority of urologists perform this step without assistance by a radiologist. Currently a wide variation of fluoroscopic guided techniques is available in clinical practice. In this work we describe the most common fluoroscopic guided access techniques in a step-by-step manner aiming to assist on the standardization of their technique and terminology...

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...

PURPOSE OF REVIEW: Simulation training for stone surgery is now increasingly used as part of training curricula worldwide. A combination of low and high fidelity simulators has been used with varying degrees of 'realism' provided by them. In this review, we discuss low and high fidelity simulators used for ureteroscopy (URS) and percutaneous nephrolithotomy (PCNL) stone procedures with their advantages, disadvantages and future direction for endourological simulation surgery. The final goal will be to understand whether or not 'realism' has to be considered as a critical element in simulation for this field...

BACKGROUND: Approximately 12% of all ureteral stents placed are retained or "forgotten." Forgotten stents are associated with significant safety concerns as well as increased costs and legal issues. Retained ureteral stents (RUS) often occur due to lack of clinical follow-up, communication or language barriers, and economic concerns. METHODS: We describe a multiplatform application that facilitates data collection to prevent RUS. The "Stent Tracker" application can be installed on mobile devices and computers...

INTRODUCTION: The progressive reduction in the calibre of the tract in percutaneous kidney surgery to the point of miniaturisation has expanded its use to smaller stones that until now have been treated with extracorporeal shock wave lithotripsy (ESWL) and retrograde intrarenal surgery (RIRS). OBJECTIVE: To provide an update on the various techniques of small-calibre nephrolithotomy (SC-PCNL) analyse their efficacy, safety and indications and determine their degree of implantation at this time...

BACKGROUND: Puncture of the renal collecting system represents a challenging step in percutaneous nephrolithotomy (PCNL). Limitations related to the use of standard fluoroscopic-based and ultrasound-based maneuvers have been recognized. OBJECTIVES: To describe the technique and early clinical outcomes of a novel navigation system for percutaneous kidney access. DESIGN, SETTING, AND PARTICIPANTS: This was a proof-of-concept study (IDEAL phase 1) conducted at a single academic center...

INTRODUCTION: To assess the clinical features, outcomes, complications, and cost-effectiveness of shockwave lithotripsy (SWL), flexible ureterorenoscopy (FURS), and percutaneous nephrolithotomy (PCNL) in the treatment of lower pole (LP) stones (10-20 mm) in a large tertiary referral center. PATIENTS AND METHODS: Consecutive patients treated for solitary LP stones (10-20 mm) between 2008 and 2013 were identified from a prospective database. SWL was used as primary treatment in all cases (following a stone multidisciplinary team assessment), with FURS and PCNL reserved for SWL contraindications, failure, or patient choice...

OBJECTIVE: To examine urine and stone bacteriology of struvite stone formers in a large cohort of patients undergoing percutaneous nephrolithotomy (PCNL). MATERIALS AND METHODS: A total of 1191 patients, with stone and urine cultures, treated with PCNL for renal calculi were included in the study. Statistical differences were assessed using Mann-Whitney U and T-tests. RESULTS: Stone cultures were positive in 72% of patients with struvite stones...

OBJECTIVE: In the perioperative period, renin-angiotensin-aldosterone system (RAAS) inhibitors may result in cardiovascular and renal functional changes. We sought to determine the acute and chronic renal functional and blood pressure effects of continuing or withdrawing angiotensin-converting enzyme inhibitors (ACE-I) and angiotensin receptor blockers (ARBs) after percutaneous nephrolithotomy (PCNL). MATERIALS AND METHODS: This was a retrospective review of all patients undergoing PCNL at our institution from 2002 to 2013...

INTRODUCTION: The treatment of large renal stones (≥1 cm) in paediatric patients is challenging. The usual treatment options include percutaneous nephrolithotomy (PCNL) or shockwave lithotripsy (SWL). There is a rise in the use of ureteroscopy and laser stone fragmentation (URSL) for paediatric stones; however, outcomes of treatment for large renal stones in this age group are still largely unknown. OBJECTIVE: To investigate the outcome of URSL for large paediatric renal stones ≥1 cm treated at the present institution over the last 5 years...

INTRODUCTION: With the evolution of endourologic technology, bilateral synchronous percutaneous nephrolithotomy (BS-PCNL) has emerged as a potentially practical intervention for patients with bilateral lithiasis. Although tradition has favored a staged approach, an increasing number of original studies have reported their experiences with the synchronous approach. MATERIALS AND METHODS: A Cochrane style search was performed after development of a sensitive and predefined search strategy...

Nephrolithiasis accelerates the renal failure in the patients with ADPKD. In order to evaluate the role of percutaneous nephrolithotomy in management of calculus in these patients, 11 patients with autosomal dominant polycystic kidney disease and renal stones were included in the study. Two patients had bilateral renal stones. All patients were treated by percutaneous nephrolithotomy under ultrasound guidance. 13 percutaneous nephrolithotomy procedures were performed in 1 stage by the urology team under ultrasound guidance...

OBJECTIVE: To report our experience of a series of percutaneous nephrolithotomy (PCNL) procedures in a single centre over 18 years in terms of patient and stone characteristics, indications, stone clearance and complications, along with the results of chemical analysis of stones in a subgroup. PATIENTS AND METHODS: We retrospectively analysed the outcomes of PCNL in 3402 patients, who underwent the procedure between 1997 and 2014, obtained from a prospectively maintained database...

Urolithiasis is a significant worldwide source of morbidity, constituting a common urological disease that affects between 10 and 15% of the world population. Recent technological and surgical advances have replaced the need for open surgery with less invasive procedures. The factors which determine the indications for percutaneous nephrolithotomy include stone factors (stone size, stone composition, and stone location), patient factors (habitus and renal anomalies), and failure of other treatment modalities (ESWL and flexible ureteroscopy)...

PURPOSE: To compare outcomes and complications of percutaneous nephrolithotomy (PCNL) in the complete supine versus semi supine position in order to select the best position. MATERIALS AND METHODS: In this clinical trial, between July 2011 and May 2014, a total of 44 patients who presented for PCNL were prospectively enrolled and randomly divided into 2 groups [complete supine (n=22), andsemi supine (n = 22)]. The results in both positions were compared regarding the complexity and outcomes...
