1 Cost-effectiveness of anti-retropulsion devices for ureteroscopic lithotripsy The Journal of Urology, May 6, 2013
Ursiny M et al. - The authors evaluated the cost-effectiveness of anti-retropulsion devices used during ureteroscopic lithotripsy. It is cost-effective to use an anti-retropulsion device at a retropulsion rate of greater than 6.3%.

2 Large-balloon dilation of the sphincter of Oddi after sphincterotomy or infundibulotomy to extract large calculi or multiple common bile duct stones without using mechanical lithotripsy Scandinavian Journal of Gastroenterology, February 5, 2013
Poincloux L et al. - The purpose was to evaluate the feasibility, efficacy and morbidity of large-balloon dilatation of the sphincter of Oddi after sphincterotomy or infundibulotomy for large or multiple common bile duct stones. ESLBD after endoscopic sphincterotomy or infundibulotomy is a simple, reproducible and effective technique, associated with a low morbidity rate and helps in avoiding mechanical lithotripsy in 95.3% of cases for the endoscopic extraction of large or ...

3 Effect of size and site on the outcome of extracorporeal shock wave lithotripsy of proximal urinary stones in children Journal of Pediatric Urology, May 9, 2013
Habib EI et al. - This study aimed to determine the effect of location and size of stones on the outcome of extracorporeal shock wave lithotripsy (ESWL) in children. ESWL is a safe and effective method for treatment of stones up to 2 cm in children. Rate of auxillary procedures increases in stones >2 cm in size. About 80% of failures were associated with stone size >1.35 cm while 52.3% of completely cleared stones were associated with size Methods In 2008–2010, 150 children ...

4 Outcome from shockwave lithotripsy to ureteric calculi in patients with high skin-to-stone distance Urology Times, May 15, 2013
Ramsey S et al. - Authors report the outcomes of SWL to ureteric calculi at an SSD of over 13cm, using a contemporary lithotriptor with a focal depth of up to 17cm. The use of a contemporary lithotriptor in an experienced centre can produce excellent stone free rates following treatment of ureteric calculi in patients with SSDs of 13cm or greater. The use of machines with greater focal depths will allow more patients to undergo SWL for urinary calculi despite increasing obesity.

5 To assess the effects of different treatment protocols on the degree of renal injury in patients with renal stones receiving shockwave lithotripsy Urology Times, May 16, 2013
Lu Y et al. - This study aims at assessing the effects of these protocols on acute renal injury in human subjects. Patients received the first 100 shocks at 40% power and a 3-minute pause, had significantly less rise in urinary IL-18, compared to those had no low-energy pretreatment and pause. This suggested that combination of the two protocols may lead to less post-SWL acute renal injury.

6 Longer operative time is associated with higher risk of severe complications after percutaneous nephrolithotomy: Analysis of 1511 cases from a Japanese nationwide database International Journal of Urology, May 2, 2013
Sugihara T et al. - This study aimed to evaluate risk factors of severe adverse events after percutaneous nephrolithotomy with an emphasis on operation time, and to develop a nomogram for predicting them. Longer operation time is a significant and independent risk factor for severe adverse events after percutaneous nephrolithotomy. This nomogram can be an effective tool for predicting postoperative complications.

7 Surgical and Endoscopic Treatment of Pain in Chronic Pancreatitis: A Multidisciplinary Update Digestive Surgery, May 6, 2013
Issa Y et al. - Chronic pancreatitis is an inflammatory disease of the pancreas with abdominal pain as the most prominent symptom. The primary goal of treatment is to achieve long-term pain relief, control of the complications associated with the disease, and to restore the quality of life. Currently, a conservative step-up approach is often used for the treatment of pain; progression to severe and intractable pain is considered necessary before invasive treatment is considered. In ...

8 Recent advances in endoscopic management of difficult bile duct stones Digestive Endoscopy, May 9, 2013
Yasuda I et al. - Endoscopic treatment is now recognized worldwide as the first-line treatment for bile duct stones. Endoscopic sphincterotomy combined with basket and/or balloon catheter is generally carried out for stone extraction. Moreover, enteroscopy has recently been used to reach the papilla. Furthermore, an endoscopic ultrasound-guided procedure has been attempted most recently. In elderly patients and those with very poor general condition, biliary stenting only is ...

9 Are small residual stone fragments really insignificant in children? Journal of Pediatric Surgery, April 26, 2013
Dincel N et al. - The study aims to assess the significance of asymptomatic residual stone fragments of less than 4mm (clinically insignificant residual fragments [CIRFs]) after shock wave lithotripsy (SWL), percutaneous nephrolithotomy (PNL), and retrograde intrarenal surgery (RIRS) in children. The results suggest that 40% of children with CIRFs will become symptomatic and 20% will develop stone re-growth over the following 6months. Only one fifth of the fragments will pass ...

10 Effects of holmium:yag laser energy settings on fiber tip degradation Urology Times, May 15, 2013
Goldsmith Z et al. - These experiments have defined, for the first time, a range of energy settings at which minimal tip degradation is observed in vitro. The setting of 1.0 J and 10 Hz is associated with significant tip degradation, which may offset fragmentation efficiency observed with this setting.
