BACKGROUND: Percutaneous nephrolithotomy remains the standard of care for kidney stones larger than 2cm. Therefore, setting a prognosis for complete stone resolution through this method is essential. The prognostic tools available have limited prediction. OBJECTIVES: To evaluate the stone-free rate in patients undergoing percutaneous nephrolithotomy with the Clinical Research Office of the Endourological Society nomogram and suggest modifications to improve the classification...

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...

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...

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...

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: Technological advances have prompted a change in the management of urolithiasis. Endourological techniques are gaining importance because they are highly effective treatments. The aim of this study was to answer the question of whether extracorporeal shock wave lithotripsy (ESWL) is still a competitive alternative compared with other therapeutic modalities. ACQUISITION OF EVIDENCE: We conducted a literature search of articles published in the past 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...

PURPOSE: Chronic unilateral hematuria (CUH) is also called lateralizing essential hematuria, benign essential hematuria, and benign lateralizing hematuria, which was defined as intermittent or continuous gross hematuria that cannot be diagnosed with standard radiology and hematology studies, together with unilateral bloody efflux by cystoscopy. CUH is rare, but sometimes confused with malignancy or life-threatening hemorrhage. Therefore, it can cause considerable anxiety to not only patients but also urologists...

Over the last decade, urinary lithiasis' prevalence has dramatically increased due to diet and lifestyle changes, growing 10.6% and 7.1% in men and women respectively. Extracorporeal shock wave lithotripsy has lost relevance in current practice due to endoscopic device development and unpredictability of results. Instrument miniaturization is leading to an increase of the percutaneous approach of increasingly smaller stones, while most flexible ureteroscopes durability and digitalization has allowed urologists to address larger stones...

An ideal treatment option for symptomatic Benign Prostatic Hyperplasia (BPH) should relieve lower urinary tract symptoms (LUTS) and restore Quality of Life (QoL). Currently available medical therapies and surgical options for symptomatic BPH have side effects that adversely affects quality of life. Prostatic urethral lift (PUL) is a novel endourology procedure that promises to relieve LUTS without the aforementioned side effects. Areas covered: We diligently reviewed all the published literature on PUL, till July 2016 using standard search criteria...

Temporary drainage of the upper urinary tract by internal ureteral stents is a routine procedure in endourology. However, it is associated with a clear side-effect profile. Our aim was to evaluate prevention and treatment options of stent-related symptoms. We carried out a systematic review according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines using MEDLINE and SCOPUS, and identified 107 appropriate records. A high number of these studies showed clear methodological limitations...
