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...

Surgeons training in the twenty-first century are subject to a myriad of pressures, as has always been the case within surgical training. These include reduced hours available for training and increased threat of litigation against their operating practice. The Halstedian approach of "see one, do one, teach one" has been replaced within surgical training and simulation has become established to enable urology trainees to develop technical and non-technical skills away from the operating room. With the primary focus as patient safety and increasing operating skill, "simulation training" encompasses several modalities...

In spite of the fact that urologic surgical techniques used by urologists are becoming more and more minimally invasive and easier because of developing technologies, surgical approaches for the urinary stones in kidneys with abnormal anatomy are still confusing. The objective of this article is to determine the treatment options in these kidneys. For this purpose, between 2005 and 2015, we retrospectively evaluated patients operated for urolithiasis with various congenital renal anomalies in five referral urology clinics in our country...

INTRODUCTION: Percutaneous nephrolithotomy (PNL) is the primary treatment modality for management of staghorn stones. PNL in supine position has important advantages over prone positon. However, studies comparing prone and supine positions for PNL in staghorn stone patients have conflicting results, and the aim of the current study was to compare prone and supine positions for PNL in staghorn stone cases. PATIENTS AND METHODS: Data of patients underwent PNL for staghorn stones in supine or prone position by a single urologist were collected prospectively...

INTRODUCTION: Anesthetic management of patients with Duchenne muscular dystrophy (DMD) is complicated because these patients are more sensitive to nondepolarizing neuromuscular blocking agents (NMBAs) and are vulnerable to postoperative complications, such as postoperative residual curarization and respiratory failure. Sugammadex is a new reversal agent for aminosteroidal NMBAs, but its safety in children is controversial. CLINICAL FEATURES: An 11-year-old boy with DMD underwent general anesthesia for a percutaneous nephrolithotomy...

We describe the use of the Uro Dyna-CT, an imaging system used in the operating room that produces real-time three-dimensional (3D) imaging and cross-sectional image reconstructions similar to an intraoperative computerized tomography, during a percutaneous nephrolithotomy and a contralateral flexible ureteroscopy in a complete supine position. A 65 year-old female patient had an incomplete calyceal staghorn stone in the right kidney and a 10mm in the left one. The procedure was uneventful and the intraoperative use of the Uro Dyna-CT identified 2 residual stones that were not found by digital fluoroscopy and flexible nephroscopy at the end of surgery, helping us to render the patient stone-free in one procedure, which was confirmed by a postoperative CT scan...
