Retrograde endoureterotomy as a treatment option for impacted calculus in the ureterointestinal junction

2021

Introduction: In patients with a history of radical cystectomy and with intestinal diversion, urolithiasis in the upper urinary tract is a frequent event. Material and methods: We describe for the first time a case of retrograde endoureterotomy used to treat a calculus proximal to the ureterointestinal junction. Results: This technique is of interest when antegrade access is not possible. In our example, after passing the guidewire percutaneously, and externalize it through the stoma, the left meatus was reached with a resectoscope inserted through the ileal duct. After the use of a balloon to prevent migration of the calculus, a retrograde endoureterotomy was performed with a Collins knife…

Prevalence of biliary lithiasis in a Sicilian population of chronic renal failure patients.

2003

BACKGROUND The aim of this study was to evaluate the prevalence of biliary lithiasis (BL) and associated risk factors in a population of undialysed patients with chronic renal failure (CRF), and to compare these with findings we had obtained previously in chronic haemodialysis (HD) patients and in subjects from the general population located in the same geographic region. METHODS A total of 118 CRF patients on conservative treatment were included in the study. In all subjects, we measured several clinical and humoral parameters potentially correlated with BL. Liver and biliary tract ultrasonography was performed with a 3.5 MHz linear probe after at least 12 h of fasting. RESULTS The prevale…

Fourier transform infrared analysis of urinary calculi and metabolic studies in a group of Sicilian children

2017

Introduction. Prevalence of urinary calculi in children has been increasing in the past years. We performed an analysis of the chemical composition of stones formers of the pediatric population in our geographical area over the years 2005 to 2013. Materials and Methods. Fourier transform infrared spectroscopy was employed for the determination of the calculus composition of a group of Sicilian children, and metabolic studies were performed to formulate the correct diagnosis and establish therapy. Results. The prevalence of stone formation was much higher for boys than for girls, with a sex ratio of 1.9:1. The single most frequent component was found to be calcium oxalate monohydrate, and ca…

Sialolitiasis parotídea del conducto de Stensen

2006

La litiasis salival es una afectación consistente en la obstrucción mecánica de una glándula salival o de su conducto excretor, debido a la formación de concreciones calcáreas o sialolitos, lo que determina una ectasía salival, pudiendo provocar la dilatación posterior de la glándula. La sialolitiasis supone el 30 % de la patología salival y afecta principalmente a las glándulas submaxilares (83 a 94 %), seguida por la glándula parótida (4 a 10 %) y las glándulas sublinguales (1 a 7 %). En este trabajo presentamos el caso de un paciente varón de 45 años que presentaba mal olor y sabor de boca en el momento de las comidas y afecto de un cálculo salival a nivel del conducto de Stensen izquier…

Electromagnetically generated extracorporeal shock waves for gallstone lithotripsy: in vitro experiments and clinical relevance.

1989

. First generation shock wave sources have been proved to disintegrate gallstones effectively, but they require the immersion of the patient's body in a tank of water. A recently developed second generation shock wave source (Siemens-Lithostar, Erlangen, FRG) generates shock waves electromagnetically. It presents several novel features. In particular the waterbath can be omitted and due to lower shock wave pressure general anaesthesia is not required. In vitro studies showed that 36 out of 38 gallstones (11–30 mm in diameter) could be disintegrated. Two concrements resisting lithotripsy were pure white cholesterol stones. Independent of shape, size, and composition (cholesterol or pigment) …

Sialoendoscopy: state of the art, challenges and further perspectives. Round Table, 101st SIO National Congress, Catania 2014

2015

This draft of the Official Round Table held during the 101(st) SIO National Congress is an updated review on sialoendoscopy, a technique used for diagnosis and treatment of obstructive pathologies of salivary glands in a minimally invasive fashion. This review treats many aspects of salivary gland endoscopy, starting from anatomy to deal with the more advanced surgical techniques and analyses the main decisional algorithms proposed in the literature. In addition, particular attention was directed to the current limitations of this technique and to the potential developments that sialoendoscopy could have in the near future.Questo testo è un estratto della Tavola Rotonda Istituzionale tenuta…
