Objectives To perform a prospective study to evaluate the renal protective effects of ramping protocol and pause protocol for extracorporeal shockwave lithotripsy in human subjects. Patients and Methods 320 patients with solitary renal stone <15mm, were randomized to receive one of four protocols: (1) 80% power from beginning until the end of treatment; (2) the first 100 SWs at 40% power, and then 80% power until the end of treatment; (3) the first 100 shocks at 40% power, followed by a 3-minute pause and then further SWs at 80% power until the end of treatment; and (4) the first 100 shocks at 80% power, followed by a 3-minute pause and then further SWs at 80% power until the end of treatment...

In Bouveret's syndrome, a biliary stone obstructs the duodenum. Surgical treatment is plagued by high morbidity and mortality. Therefore, endoscopic treatment has become a first-line approach. Areas covered: A literature search of Medline and Google Scholar databases was performed using the terms endoscopic treatment, non-operative treatment, Bouveret's syndrome, and gallstone ileus. Sixty-one cases of successful endoscopic treatment were found over the period 1978-2016 and are summarized herein. Therapeutic modalities used in 52 patients with complete success included mechanical lithotripsy (40% of cases), electrohydraulic lithotripsy (21% of cases), extraction of the intact stone and laser lithotripsy (15% of cases each), extracorporeal shockwave lithotripsy and duodenal stenting (4% of cases each)...

We evaluated the clinical value of flexible ureteroscopic lithotripsy for the treatment of upper urinary tract calculi in infants. Fifty-five infants with upper urinary tract calculi were included in this study: 41 males and 14 females. Retrograde intrarenal surgery was performed by an 8 Fr/30 cm flexible ureterorenoscope (POLY®) combined with a holmium laser. CT scanning or radiography of the kidneys, ureters, and bladder region was performed one month after the operation to confirm the clearance of calculi...

Gallstone disease is a common and frequently occurring disease in human, and it is the main disease among the digestive system diseases. The incidence of gallstone disease in western countries is about 5%-22%, and common bile duct stones (CBDS) accounts for 8%-20%. CBDS easily lead to biliary obstruction, secondary cholangitis, pancreatitis, and obstructive jaundice, even endanger life. Therefore, it needs timely treatment once diagnosed. The recurrence of choledocholithiasis after bile duct stones clearance involves complicated factors and cannot be completely elaborated by a single factor...

INTRODUCTION: Extracorporeal shockwave lithotripsy (SWL) is one of the most frequently performed procedures in patients with urolithiasis. For ureter-localized stones, SWL is often preceded by a double J stent insertion. However, fear of serious complications, including sepsis associated with stents, is often expressed. The following study assessed the impact of stent insertions on the results of SWL in patients with ureteric stones. MATERIAL AND METHODS: The study group consisted of 411 ureteric stone patients who were treated with SWL from January 2010 to December 2014...

PATIENTS AND METHODS: This study was prospectively performed in two hospitals (Althawrah Modern General Hospital, and Ibn Sina Specialized Hospital) between November 2012 and November 2015. In all, 44 patients presented with urethral or bladder stones.

Extracorporeal shockwave therapy (ESWT) has shown chondroprotective effects on the initiation of the osteoarthritis (OA) changes of the rat knee. This study evaluated 69 significant expressed profiles of microRNA (miRNA) in the articular cartilage and subchondral bone after ESWT. There were 118 target genes identified for miRNAs of interest in articular cartilage and 214 target genes in subchondral bone by next generation sequencing (NGS). In principal component analysis (PCA), the relationships of miRNA expression in bone and cartilage were improved after ESWT...

As a type of mechanical stimulation, extracorporeal shockwave (ESW) has been widely used in the clinic to treat bone fracture delayed union and non-unions. A large number of studies have shown beneficial effects of ESW in promoting fracture healing by inducing bone regeneration; however, the underlying mechanisms remain unclear. ESW has been shown to induce the production of prostaglandin E2 (PGE2), which is essential for gap junction intercellular communication in response to mechanical stress. Among the 19 known gap junction subunits, connexin43 (Cx43) is the most prevalent for mediating the response of mechanical stress...

OBJECTIVE: To describe clinical and diagnostic findings as well as management of adhesive capsulitis in dogs. BACKGROUND: Adhesive capsulitis, also known as frozen shoulder, is a syndrome defined by loss of range of motion of the shoulder and may be the end-stage manifestation of several primary conditions. EVIDENTIARY VALUE: This is a case series report of eight dogs with chronic forelimb lameness diagnosed with adhesive capsulitis. METHODS: Medical records (June 1, 2010-September 1, 2015) including, physical examination findings, radiographic findings, magnetic resonance imaging (MRI) findings, arthroscopy findings, and treatment plans were reviewed...

Supraspinatus tendinopathy (ST) and biceps tendinopathy (BT) are common causes of forelimb lameness in large-breed dogs and have historically been treated with conservative management or surgery. Extracorporeal shockwave therapy (ESWT) and therapeutic exercise (TE) are thought to be treatment options for these conditions. The objectives of this study were to report the clinical presentations of dogs treated with ESWT for shoulder tendinopathies, to determine the association between shoulder lesion severity identified on ultrasonography or MRI and outcome, and to compare the outcomes of dogs treated with ESWT with and without TE...

Osteoarthritis (OA) is characterized with pathological changes on articular cartilage and subchondral bone, with clinical symptoms of pain and motor dysfunction in affected joints. A growing number of investigations demonstrated the therapeutic effects of extracorporeal shockwave therapy (ESWT) on joints with OA. While the partial mechanisms of action are based on cellular mechanotransduction through cytoskeleton into nuclei to regulate gene expression and cause biophysical influences, the efficacy and exact mechanisms are still under exploration...

INTRODUCTION AND OBJECTIVE: The manufacturer for the Storz Modulith SLX-F2 lithotripter recommends treatment head exchange after 1.65 million shocks. However, there is no documentation describing longevity of the treatment head with continued usage. The objective of this study is to determine whether there is a difference in stone fragmentation effectiveness with the treatment head at the beginning versus the end of its treatment life. METHODS: We conducted a retrospective chart review of 200 patients-50 consecutive patients treated immediately preceding, and following, two separate treatment head exchanges...

Extracorporeal Shock Wave Therapy (ESWT), after its first medical application in the urological field for lithotripsy, nowadays represents a valid therapeutical tool also for many musculoskeletal diseases, as well as for regenerative medicine applications. This is possible thanks to its mechanisms of action, which in the non-urological field are not related to mechanical disruption (as for renal stones), but rather to the capacity, by mechanotransduction, to induce neoangiogenesis, osteogenesis and to improve local tissue trophism, regeneration and remodeling, through stem cell stimulation...

BACKGROUND: Extracorporeal shockwave therapy (ESWT) is emerging as a potential new treatment option for a variety of clinical scenarios including promotion of wound healing and symptom control in end-stage ischemic heart disease. A number of small trials have investigated ESWT in the management of peripheral arterial disease (PAD). A systematic review of the literature was performed investigating the efficacy and potential mechanism of action of ESWT for PAD. METHODS: A systematic review was conducted using MEDLINE and PubMed databases in keeping with the standard reporting guidelines set by the Preferred Reporting Items for Systematic Reviews and Meta-Analysis group to identify any publications relating to the use of ESWT in PAD...
