PURPOSE: We compared the outcomes of SWL to treat distal ureter stones with regard to the conventional prone and supine positions using the transgluteal approach through the greater sciatic foramen. METHODS: A prospective, randomized, single-blind, and multicenter study was conducted between October 2014 and July 2015. The inclusion criteria were radio-opaque distal ureter stones with a maximum diameter of 0.5-2 cm as measured on a CT scan. The included 160 patients were randomly assigned to two groups: the prone group (n = 80; treated in the conventional prone position) and the transgluteal group (n = 80; treated in the supine position using a transgluteal approach)...

Interventional treatment of stones essentially consists of three treatment modalities. Extracorporeal shockwave lithotripsy (ESWL), in addition to uterorenoscopy (URS) and percutaneous nephrolitholapaxy (PCNL) is an essential treatment pillar and is the only noninvasive therapy option for the treatment of urinary stones. After a long period of ESWL being the leading choice in stone treatment, the number of SWL interventions diminished in recent years in favor of the other two treatment modalities (URS and PCNL)...

Ureteral stent placement is a common procedure in urologic practice. Forgotten, encrusted D/J stents represent a difficult problem for urologists. The major complications are infection, impaired renal function, migration, encrustation, stone formation and multiple fragmentation of stent. A consensus on the best therapeutic approach is still lacking. Here we present our experience with endoscopic management of this challenging problem and discuss the multimodal endourologic approaches for treating forgotten, encrusted ureteral stents...

In recent years, the incidence of nephrolithiasis in the pediatric population appears to be increasing.1 This has placed a new emphasis on surgical management of stones in children. In the past, extra-corporeal shockwave lithotripsy (ESWL) was the preferred management technique for stones in children.2 More recently, though, advances in endoscopy have allowed ureteroscopy to be adapted to the pediatric population and this approach has become more frequently utilized not just for lower ureteral calculi but also for proximal ureteral and renal stones...

PURPOSE: To identify the role of shock wave lithotripsy (SWL) and flexible ureterorenoscopy (f-URS) on the stone recurrence, in the management of 10-20 millimeter lower pole stone (LPS) with medium follow-up outcomes. MATERIALS AND METHODS: The patients' charts which were treated with SWL or f-URS for LPS between January 2011 and September 2013 were analyzed, retrospectively. Patients who had a solitary 10-20mm LPS were enrolled into the study. In both procedures, patient was accepted as stone free, if complete stone clearance was achieved in the 3rd month abdominal computed tomography...

Alpha blockers (AB) are the main group of drugs used for medical expulsive therapy (MET) in patients with ureteral stones. However, there is no consensus on the relative efficacy and safety of individual AB in MET. Areas covered: The present work is a network meta-analysis of randomized controlled trials comparing AB with either placebo or standard of care in patients with ureteral stones. Electronic databases of Medline, Cochrane CENTRAL and Google Scholar were searched for eligible clinical studies. Inverse variance heterogeneity model was used for mixed treatment comparisons...

Purpose Nephrolithiasis is an increasingly common ailment in the United States. Ureteroscopic management has supplanted shockwave lithotripsy as the most common treatment of upper tract stone disease. Ureteral stricture is a rare but serious complication of stone disease and its management. The impact of new technologies and more widespread ureteroscopic management on stricture rates is unknown. We describe our experience in managing strictures incurred following ureteroscopy for upper tract stone disease. Materials and methods Records for patients managed at 4 tertiary care centers between December 2006 and October 2015 with the diagnosis of ureteral stricture following ureteroscopy for upper tract stone disease were retrospectively reviewed...

PURPOSE: To help rein in surgical spending there is growing interest in the application of payment bundles to common outpatient procedures like ureteroscopy and shock wave lithotripsy. However, before urologists can move to such a payment system they need to know where episode costs are concentrated. MATERIALS AND METHODS: Using claims data from MVC (Michigan Value Collaborative) we identified patients who underwent ureteroscopy or shock wave lithotripsy at hospitals in Michigan from 2012 to 2015...

It is well recognized that the popularity of extracorporeal shock wave lithotripsy (SWL), despite its non-invasive character, has decreased during recent years. This is partly explained by the technological achievements in endoscopy and urologists' enthusiasm for such procedures. Another explanation is that many urologists have been insufficiently successful with SWL. The latter effect might to some extent be a result of the performance of the lithotripter used, but in too many cases, it is evident that the principles of how shock wave lithotripsy should be carried out are poorly applied...
