ESWL Prediction of outcome and failure Prevention
2007
Based on our own experiences and a review of the recent literature, this article evaluates recent developments in predicting outcomes and failures of shockwave lithotripsy when treating patients with urinary tract stones. After a detailed MEDLINE research, the authors identified several variables that influence and predict extracorporeal shockwave lithotripsy (ESWL) success. These variables may be categorized as stone variables, patient variables and operator variables. Only multivariate analysis on a large number of homogenous patients may offer an objective evaluation of the factors conditioning ESWL outcome.
Analysis of radiolucent gallstones by computed tomography for in vivo estimation of stone components.
1990
. Successful oral litholytic and other non-operative therapies of gallstones require exact determination of the stone components. Since computed tomography (CT) provides highly sensitive measurement of density, we performed a study to evaluate whether CT measurement of stone density allows a prediction of the composition of radiolucent gallstones. Twenty-eight patients presenting with 29 radiolucent gallbladder (n= 17) or common bile duct stones (n=12) were included. Prior to operative or endo-scopic therapy the attenuation values (Hounsfield Units, HU) were assessed in vivo by CT under standardized conditions (Somatom II, 125 KV, 130 mAs). After surgical or endoscopic stone removal the con…
Imaging modalities and treatment of paediatric upper tract urolithiasis: A systematic review and update on behalf of the EAU urolithiasis guidelines …
2020
Prompt diagnosis and treatment of paediatric urolithiasis are required to avoid long term sequelae of renal damage.To systematically review the literature regarding the diagnostic imaging modalities and treatment approaches for paediatric urolithiasis.PubMed, Science Direct, Scopus and Web of Science were systematically searched from January 1980-January 2019. 76 full-text articles were included.Ultrasound and Kidney-Ureter-Bladder radiography are the baseline diagnostic examinations. Non-contrast Computed Tomography (CT) is the second line choice with high sensitivity (97-100%) and specificity (96-100%). Magnetic Resonance Urography accounts only for 2% of pediatric stone imaging studies. …
Future perspectives of flexible ureteroscopy
2019
Purpose of review In the recent past, there were numerous and promising technological developments in the field of endourology leading to tremendous changes in the management of urolithiasis. This review will try to weave ancient stone therapy with the very modern advent of flexible ureteroscopy and recent developments in robotic systems. Recent findings In the broad field of flexible ureteroscopy for stone surgery, new disposable scopes have been developed and established. The use of robotic instruments is also a new and interesting concept. Additionally, clinical research on the understanding of laser features leads to a specific and appropriate use of lasers for lithotripsy, both holmium…
Nastanak i liječenje gigantskih kamenaca ileocekalnog urinskog spremnika u pacijenta liječenog cistektomijom zbog intersticijskog cistitisa: prikaz s…
2021
Cilj: Cilj ovoga rada je prikazati pacijenta s intersticijskim cistitisom u kojega je došlo do stvaranja kamenaca u novoformiranom urinskom spremniku. Prikaz slučaja: Pacijent star 48 godina obrađivan je zbog recidivnih infekcija mokraćnog sustava. Prethodno mu je zbog intersticijskog cistitisa, koji je znatno utjecao na njegovu kvalitetu života, učinjena cistektomija uz oblikovanje urinskog spremnika (Mainz-pouch I). Urološkom obradom pronađena su u području urinskoga spremnika dva velika kamenca dimenzija 77 × 74 mm te 76 × 62 mm uz obostranu hidronefrozu. Kako bi se riješio uzrok rekurentnih urinarnih infekcija, učinjena mu je otvorenim pristupom ekstrakcija oba kamenca. Poslijeoperacijs…
Fragmentation of bile duct stones: a prospective systematic in vitro evaluation of argon plasma coagulation, cryotechnology, and water-jet technology
2009
Background and study aim Choledocholithiasis is a common disease in the West. Lithotripsy by mechanical methods using baskets and by laser or electrohydraulic methods varies in effectiveness. With argon plasma coagulation (APC), high temperatures are used for devitalization and fragmentation; cryogenic techniques use the selective controlled application of freeze-thaw cycles to devitalize pathological tissue; and the dissecting water jet exploits the high pressure action of a thin laminar jet. We aimed to assess the feasibility and effectiveness of APC, cryotechnology, and the dissecting water jet as options for the fragmentation of bile duct stones. Methods In an in vitro feasibility study…
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…
A case report of coexistence of a sialolith and an adenoid cystic carcinoma in the submandibular gland
2006
Ôhe occurrence of sialoliths in the submandibular gland is 80% due to the specific anatomy of both the gland and its duct. The diagnosis is rather easy because of the obvious clinical signs of the entity. Imaging studies are always necessary in order to treat the patient as effectively as possible. The stones do not tend to occur within the gland as frequently as in the respective duct. The coexistence of sialoliths and malignant tumors is extremely rare. A 70-year-old woman with intraparenchymal stone was operated in our ENT department. In addition to the sialolith the pathological examination revealed the existence of an adenoid cystic carcinoma (ACC), that extended to the neighboring ske…
Ureteral stent encrustation: evaluation of available scores as predictors of a complex surgery
2022
Background: Stent Encrustation is an uncommon event (13%) with a significant impact in patients' management. Aim of our study was to evaluate the available grading systems for encrusted stents. Methods: A retrospective analysis of encrusted stents was performed in four Italian centers between 2006 and 2020. Encrusted stents were classified according to four classifications: the Forgotten Encrusted Calcificated (FECal) score, the Kidney Ureter Bladder (KUB) score, the Visual Grading for Ureteral Encrusted Stent Classification and the Encrustation Burden Score (EBS). Classifications were evaluated to predict complex surgery defined as: long operative time (>60min); need of more than one su…

2021
Visā pasaulē, tajā skaitā arī Latvijā, viena no biežākajām ķirurģiskajām saslimšanām, kam nepieciešama operatīva ārstēšana, ir žultsakmeņu slimība (ŽAS) jeb holelitāze. Tās izplatība pieaug līdz ar iedzīvotāju vecumu un mūsdienu dzīvesveida paradumiem, tādiem kā, nesabalansēts, neregulārs uzturs un mazkustīgs dzīvesveids. Šis bakalaura darbs tika izveidots ar mērķi - noskaidrot iedzīvotāju zināšanas par žultsakmeņu slimības attīstību veicinošajiem faktoriem un profilaksi. Pirms pētījuma veikšanas, lai pārliecinātos par anketas jautājumu saprotamību, tika veikts pilotpētījums, aptaujājot desmit respondentus.
