A Neisius
BACKGROUND: Shock wave lithotripsy (SWL) became the therapy of choice for the majority of patients with urolithiasis early after its introduction in the early 1980s. Since then, SWL remains the only noninvasive therapy modality for the treatment of urinary stones. Although lithotripters became more versatile and affordable-making them available worldwide-indications for SWL have shifted as well. In most western countries, endoscopic techniques took the lead in stone therapy due to high (early) stone-free and better reimbursement rates...

The aim of the study to compare low and intermediate shock wave frequency rates in terms of success and complications for treating pediatric kidney stones. This retrospective study was performed on 58 consecutive pediatric patients (24 girls, 34 boys) who underwent shock wave lithotripsy (SWL) for kidney stones with an electrohydraulic lithotripter between April 2014 and March 2016. In the first year, all children underwent SWL with a frequency of 90 SWs/min as an intermediate frequency (Group 90), and in the second year all children were treated by SWL using 60 SWs/min as a low frequency (Group 60)...

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...

The main aim in the treatment of renal stones is to clearance of the stones completely with the least morbidity. Parallel to the improvements in technology during recent years, new flexible ureterorenoscopes and effective lithotripters such as holmium laser have been developed, thus retrograde intrarenal surgery (RIRS) has become an efficient and safe option in the management of urinary system stone disease with a gradually increasing popularity. Therewithal, innovations in auxiliary equipment such as guide-wires, ureteral access sheath and stone baskets have made this procedure more effective...

PURPOSE: Intracorporeal lithotripsy is becoming the most commonly used surgical method of stone treatment in Urology. The five major types of intracorporeal lithotripters are ultrasonic, ballistic, and combination lithotripters as well as laser and electrohydraulic lithotripters. The advantages and disadvantages of choosing each of these treatment modalities are reviewed. METHODS: Extensive review of literature was performed to identify the types of intracorporeal lithotripters...

PURPOSE: Holmium:YAG laser is the most used laser for urolithiasis. Generally, we use metallic scissors to cut the fiber tip to restore its effectiveness. Many cleaving methods have been described to avoid fiber damage and to restore its greatest power to the fiber. There is a lack of information regarding which cleaving method should be used and its effect on the fiber. In order to compare these effects, we studied different cleavage methods in terms of power output and its effects on the fiber...

The objective of this study was to determine risk factors of hospital admission for treatment of complications after extracorporeal shock wave lithotripsy (SWL). The electronic files and images of all patients who underwent SWL for treatment of renal stones between January 2011 and December 2015 were retrospectively reviewed. All patients underwent SWL with the same electromagnetic lithotripter (Dornier Lithotripot S). The data of those who needed hospital admission for treatment of complications within 30 days after SWL were compared with patients who did not require hospital admission...

INTRODUCTION: Understanding the factors affecting success of extracorporeal shockwave lithotripsy (SWL) would improve informed decision-making on the most appropriate treatment modality for an individual patient. Although stone size and skin-to-stone distance do correlate with fragmentation efficacy, it has been shown that stone composition and architecture, as reflected by structural heterogeneity on CT, are also important factors. This study aims to determine if CT texture analysis (CTTA), a novel, nondestructive, and objective tool that generates statistical metrics reflecting stone heterogeneity, could have utility in predicting likelihood of SWL success...

INTRODUCTION AND OBJECTIVES: Although extracorporeal shock wave lithotripsy (ESWL) is the first choice for pediatric renal calculi <2 cm, the success rate after the first session is low. This is in contrast to other minimally invasive procedures like percutanous nephrolithotomy (PCNL) and retrograde intrarenal surgery (RIRS), which have higher rates of success. Therefore, the present study sought to identify predictors of success after one session of ESWL. PATIENTS AND METHODS: A prospective study including 100 children with renal stone burden <2 cm who underwent ESWL at the present institution...

INTRODUCTION: Sialendoscopy has changed the management of obstructive sialadenitis. Nowadays, minimally invasive techniques evolve to preserve salivary gland function. Intraductal lithotripsy allows stones fragmentation and retrieval without opening the salivary duct. We report our experience with the StoneBreaker (SB), a new lithotripter with improvement using a sterile bag that permits reuse of the SB without passing to sterilization. TECHNICAL NOTE: The non-sterilized SB was used into a sterile camera sleeve in 5 patients, 3 submandibular lithiases and 2 parotid lithiases...

OBJECTIVE: To investigate the impact of lithotripter focal width on stone fragmentation. MATERIALS AND METHODS: A modified reflector was used to reduce -6 dB beam size of the HM3 lithotripter, while increasing concomitantly peak pressure. Fragmentation in vitro was assessed with modified and original reflectors using BegoStone phantoms. A membrane holder was used to mimic lithotripsy in vivo, and a matrix holder was used to assess variations of fragmentation power in the focal plane of the lithotripter field...

Background/study aims Laser lithotripsy can effectively fragment complicated biliary stones, but current cholangioscopes are limited by fragility, restricted mobility or moderate visual resolution. The efficacy and safety of a new digital single-operator peroral cholangioscope to guide laser lithotripsy were evaluated. Patients and methods In this prospective single-center series, consecutive patients with complicated biliary stones, defined as impacted stones > 1.5 cm in size and wider than the more distal common bile duct, or stones that failed extraction by basket mechanical lithotripsy, underwent ERCP and SpyGlass DS peroral cholangioscope (Boston Scientific, Marlborough, United States)-guided laser lithotripsy...

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...

Objective. Treatment options for urolithiasis in children include URSL and RIRS. Various types of energy are used in the disintegration of deposits in these procedures. We decided to evaluate the usefulness of URSL and RIRS techniques and compare the effectiveness of pneumatic lithotripters and holmium lasers in the child population based on our experience. Materials and Methods. One hundred eight (108) children who underwent URSL and RIRS procedures were enrolled in the study and divided into two (2) groups according to the type of energy used: pneumatic lithotripter versus holmium laser...
