Electromagnetically Generated Extracorporeal Shock Wave Lithotripsy and Adjuvant Combined Oral Litholysis for Therapy of Symptomatic Gallbladder Ston…
1991
A prospective study was conducted to evaluate effectivity, problems and adverse effects of extracorporeal shock wave lithotripsy (ESWL) using a newly developed electromagnetic biliary lithotriptor (Lithostar Plus, Siemens, Erlangen, FRG) for the treatment of selected patients presenting with symptomatic cholecystolithiasis. In addition to generally accepted criteria for the selection of patients, gallbladder contractility was established and pigment stones were excluded by computed tomography (CT). 80 out of 486 patients (63 females, 17 males, mean age 36, range 17-76 years) were selected for ESWL using a standardized diagnostic program. 62 out of 80 patients participating in the study had …
Treatment of Bladder Stones in Adults and Children: A Systematic Review and Meta-analysis on Behalf of the European Association of Urology Urolithias…
2019
Bladder stones (BS) constitute 5% of urinary stones. Currently, there is no systematic review of their treatment.To assess the efficacy (primary outcome: stone-free rate [SFR]) and morbidity of BS treatments.This systematic review was conducted in accordance with the European Association of Urology Guidelines Office. Database searches (1970-2019) were screened, abstracted, and assessed for risk of bias for comparative randomised controlled trials (RCTs) and nonrandomised studies (NRSs) with ≥10 patients per group. Quality of evidence (QoE) was assessed using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) tool.A total of 2742 abstracts and 59 full-text article…
Are morphology and composition of gallstones related? An x-ray diffraction study
1994
Abstract An x-ray diffractometric technique was used to study the crystalline composition of gallstones removed during surgery from 106 patients. Monohydrate cholesterol was found in the stones of 70 (66%) patients, either alone (33%) or in association with calcium salts (33%). The anhydrous form of cholesterol was found in the stones of 28 (26%) patients, either alone (10%) or in association with calcium salts (16%). These salts (vaterite, aragonite, and calcite) were found in 50% of cases in varying amounts (from 12% to 15% of the stone weight). Eight stones contained no cholesterol: 4 showed an amorphous pattern and 4 were composed of calcium carbonate salts. In 7 of 8 patients with bile…
Intraoperative cholangiography during cholecystectomy using a biliary-nose tube: Routinely used in patients with main bile duct stones
2021
Background: Nowadays, the “gold standard” treatment for gallbladder stones is laparoscopic cholecystectomy but the risk of iatrogenic biliary duct injuries is increased compared to “open” surgery. Intraoperative cholangiography (IOC) can be useful to avoid biliary injuries but it can also be a no-safe procedure in center in which it is not routinely performed. Aim and objective: The aim of our study is to trust the efficacy of IOC in a patient with common bile duct (CBD) and gallbladder stones using a biliary-nose tube. Materials and methods: 135 patients with gallbladder and CBD stones were treated with sequential therapy and randomly divided into two groups. Laparoscopic cholecystectomy w…
Development of Bladder Carcinoma Following Portacaval Shunt in Rats
1987
Portacaval anastomosis (PCA) was first introduced by Eck (1877) and was investigated in a number of different animals. Lee et al. (1961; 1974) published a reliable method with low mortality in rats. The occurrence of urolithiasis in rats following portacaval anastomosis happened to be noticed by chance. It was published by Herz et al. (1972a, 1972b, 1973), who defined the portacaval shunt rat as an experimental model. Heine et al. (1979) described dysplastic and neoplastic changes of the bladder mucosa following portacaval anastomosis. His findings were confirmed by Duy et al. (1981); Grun et al. (1982), and Dubuisson et al. (1984). However, Wallace et al. (1984) found papillary hyperplasia…
Extrakorporale Stoßwellenlithotripsie von Gallenblasensteinen: Wie viele Patienten sind geeignet?
2008
The proportion of patients with gallbladder stones suitable for extracorporeal shockwave lithotripsy (ESWL) was analysed prospectively in 200 patients aged 17-76 years (62 males, 138 females) with symptomatic cholecystolithiasis. Criteria for inclusion were clinical symptoms, solitary stones (diameter 10-30 mm) or up to three stones with comparable total volume, contractile gallbladder, no calcification of stones, normal biliary tract anatomy. To check these criteria a step-by-step diagnostic procedure was instituted which consisted of history, ultrasonography with contractility test, abdominal X-ray film, computed tomography measurement of stone density, and endoscopic retrograde cholangio…
Lithotripsy of gallbladder stones in 1992: Improved indications and actual results
1992
ESWL of gallbladder stones and subsequent adjuvant oral dissolution is a safe and comfortable therapy of symptomatic cholecystolithiasis. This method is limited on highly selected 10 to 15% of patients. Recent experience indicates that the ideal indication is given in patients with radiolucent solitary gallstones (diameter ≤2 cm) which are harboured in a gallbladder with unimpaired contractility. 1 year after ESWL 80% of those patients present with a stone free gallbladder. Computed tomography of gallstones may probably improve selection of patients and therapeutic success.
