The performance of transabdominal ultrasound (US) in chronic pancreatitis (CP) following the advances in US technology made during recent decades has not been explored. Our aim in this prospective study was to evaluate the diagnostic accuracy of modern abdominal US compared with the Mayo score in CP. One hundred thirty-four patients referred for suspected CP were included in the study. Fifty-four patients were assigned the diagnosis CP. After inclusion, transabdominal US was performed. Ductal features (calculi, dilations and caliber variations, side-branch dilations and hyper-echoic duct wall margins) and parenchymal features (calcifications, cysts, hyper-echoic foci, stranding, lobulation and honeycombing) were recorded...

Uric acid calculi can also be treated without surgery, with simple medical lytic therapy. After appropriate dietary adjustments and add of mineral water, the needed amount of alkali supplementation can increase pH values of the urine in order to dissolve the stones. Treatment should be prolonged to prevent stone recurrence. A case of bilateral renal uric acid stones that were successfully treated by alakalizing treatment was presented.

OBJECTIVE: Urolithiasis of the transplanted kidney has an incidence of 0.2 to 1.7%, it increases the risk of infection in immunosuppressed patients and it can lead to ureteral obstruction that is often associated with deterioration of renal function. Urolithiasis of the transplanted kidney has different characteristics compared to the native kidney, due to the absence of innervation, which does not lead to colic pain. Percutaneous approach is an optimal choice in transplant patients. MATERIAL AND METHODS: Here we report our experience in two cadaveric transplant patients with urolithiasis...

PURPOSE: Prostatic calculi (PC) are usually associated with benign prostatic hyperplasia or chronic inflammation. However, in several studies prostatic inflammation and calcification have been implicated in the pathogenesis of prostate cancer (CaP). We evaluated the prevalence of PC during transrectal ultrasound (TRUS) and correlate the ultrasonographic patterns with histological findings. METHODS: A prospective study of 664 patients undergoing TRUS and prostate biopsy was planned...

CONTEXT: Extracorporeal shockwave lithotripsy (SWL) is the first-line treatment for renal calculi in most cases. Recent technology has allowed lithotriptor machines to localize stones using fluoroscopy or ultrasound (US). AIM: The aim of this study is to compare stone free rates (SFR) using two techniques. METHODS: This is a single center retrospective cohort study. We have studied 95 patients with renal calculi undergoing first SWL treatment with localization using US (48 pts) and fluoroscopy (47 pts)...

BACKGROUND: Stone retropulsion represents a challenge for intracorporeal lithotripsy of ureteral calculi. The consequences are an increased duration and cost of surgery as well as decreased stone-free rates. The use of additional tools to prevent proximal stone migration entails further costs and risks for ureteral injuries. We present the simple technique of using a coil of the routinely used guidewire to prevent stone retropulsion. METHODS: We retrospectively evaluated all patients with mid-to-proximal ureteral stones in 2014, which were treated by ureteroscopic lithotripsy (Ho: YAG and/or pneumatic lithotripsy)...

OBJECTIVES: Although previous studies have indicated that stone heterogeneity can affect shock wave lithotripsy outcomes, there is no established measurement of stone heterogeneity on computed tomography imagery. We investigated whether variation coefficient of stone density can predict shock wave success. MATERIALS AND METHODS: We conducted a retrospective review of 245 patients with urinary calculi who had undergone shock wave lithotripsy. We compared the predictive powers of treatment success between variation coefficient of stone density and other parameters associated with computed tomography attenuation...

Flexible ureteroscopy in the last few years has become a valid alternative to extracorporeal shock-wave and percutaneous nephrolithotomy even for larger renal calculi. Since 2012, ELMED (Ankara, Turkey) has been working on a robot specifically designed for flexible ureteroscopy. Today we know of the mechanics and electronic parts of Roboflex, what is unknown is the flow rate that the pump develops. We've taken a container connected to the irrigation system of the pump and we measured the quantity of saline solution for each speed...

Transoral submandibular duct sialolith removal is a simple technique with very few complications. Nevertheless, following this procedure, we have observed long-term calculus recurrence in a number of patients. We therefore elected to evaluate these cases. This was a monocentric prospective study performed between November 2013 and June 2014. All patients received surgery for submandibular gland lithiasis by intraoral removal of submandibular duct calculi. Between the day following the procedure and 3 months postsurgery, these patients systematically underwent an ultrasound examination of the submandibular gland...

Pyloric duodenal stenosis is usually caused by pyloric, juxtapyloric or duodenal ulcer, or by postbulbar ulcer. Gallbladder cancer (GBC), duodenal diverticula, annular pancreas and superior mesenteric artery syndrome (Wilkie's syndrome) are rare causes of pyloric duodenal stenosis. The case of a 66-year-old female patient is presented. The patient was admitted to hospital presenting anorexia, repeated alimentary vomiting, epigastric pain, and weight loss. Objective clinical examination upon admission: clapotage à jeun is present, triggered by tapping the epigastric region...
