[Ab] Abstract:Con toda seguridad aparecerán más estudios para alcanzar un nivel de evidencia adecuado en sus indicaciones, asicomo para optimizar su tecnica, mejorar sus resultados y reducir el riesgo de complicaciones. También conoceremos la durabilidad del equipo y podremos analizar su coste-efectividad frente a otras opciones de tratamiento de la litiasis renal. Y probablemente, la microperc ampliara su indicacion a casos en los que se puede utilizar combinándolo con otras técnicas. En definitiva, la NLPC-micro o microperc va a aportar nuevas posibilidades en el tratamiento de la litiasis renal, pudiendo seleccionarla como modo de tratamiento único o aumentar su espectro de uso combinándola con otras tecnicas. En este sentido, podemos definir a la microperc como un nuevo paso adelante en la busqueda de la menor invasividad en el tratamiento de la litiasis renal.

[Ab] Abstract:BACKGROUND: Disturbances in lipid metabolism which occur during hypothyroidism leadto the formation of gallstones. This study aims to evaluate the thyroid functionpattern in patients with common bile duct (CBD) stones. METHODS: This case-control study recruited 151 patients with preliminary diagnosesof CBD stone who underwent ERCP (cases). The control group comprisedhealthy people who met the study criteria in the same hospital. The controlgroup underwent ultrasonography to exclude any asymptomatic bile duct lithiasis.A questionnaire that included demographic and anthropometrics datawere completed by an assigned physician. Morning blood samples that followed12 hours of fasting were taken from all participants for measurements ofserum total thyroxin (T4), serum thyroid stimulating hormone (TSH), fastingblood sugar (FBS), triglycerides (TG), total cholesterol, low density lipoprotein(LDL) and high density lipoprotein (HDL). RESULTS: The mean TSH in patients (2.59 ± 4.86mg/dl) was higher than the controlgroup (2.53± 4.13 9mg/dl). In subclinical hypothyroidism, serum TSH levelshigher than 5 MU/L were found in 30.6% of cases compared with 22.5% ofcontrols [OR: 1.53; 95 % confidence interval (95% CI): 0.968-2.438). Hypothyroidismwas detected in 10.8% of the control group and in 11.3% of cases(OR: 1.87; 95% CI: 0.578-2.043). The mean total cholesterol levels in caseswas higher than the control group (p=0.61).The levels of TG (p=0.05), HDL(73.35 vs. 46.41; p<0.01) and LDL (64.81.88 vs. 111.04; p<0.01) was statisticallysignificant between both groups. CONCLUSION: There is an association between thyroid disorders and the presence of bileduct stones. Thyroid testing in patients with gallstone and bile duct stones isrecommended because hypothyroidism may be a predisposing factor for stonepassage from the gallbladder.

[Ab] Abstract:PURPOSE: The purposes of the study were to determine the frequency and magnitude of extension of computed tomographic (CT) scans performed for the evaluation of urolithiasis, to investigate the potential contributing factors for overscanning, and to establish potential landmarks to assist in estimating the location of the superior margin of the kidneys. MATERIALS AND METHODS: This is a retrospective review of 300 CT studies performed for evaluation of urolithiasis. The total length of the scanned area, performing technologist, and the patient demographics were collected. RESULTS: We found that scanning beyond the defined z-axis boundaries is a common phenomenon in CT examinations in patients with suspected urolithiasis with a magnitude that correlates (P < 0.0001) with patient time and setting: greater in the emergent (78.3 mm) and inpatient (79.8 mm) settings as well as on-call hours (80.4 mm). Our study also shows the superior margin of T11 to be consistently within 3 mm of the superior margin of the kidney but not below it. CONCLUSIONS: Overextension along the z axis is a ubiquitous phenomenon. The appropriate prescription of scan length, however, is an easy, efficient, costless, and universally applicable strategy. In patients with suspected urolithiasis, the superior margin of T11 represents a potential landmark to assist in estimating the upper margin of the kidneys.

[Ab] Abstract:AIM: To compare the outcomes of concomitant cholangiocarcinoma (C-CCA) and subsequent cholangiocarcinoma (S-CCA) associated with hepatolithiasis. METHODS: From December 1987 to December 2007, 276 patients underwent hepatic resection for hepatolithiasis in Changhua Christian Hospital. Sixty-five patients were excluded due to incomplete medical records and the remaining 211 patients constituted our study population base. Ten patients were diagnosed with C-CCA based on the preoperative biopsy or postoperative pathology. During the follow-up period, 12 patients developed S-CCA. The diagnosis of S-CCA was made by image-guided biopsy or by pathology if surgical intervention was carried out. Patient charts were reviewed to collect clinical information. Parameters such as CCA incidence, interval from operation to CCA diagnosis, interval from CCA diagnosis to disease-related death, follow-up time, and mortality rate were calculated for both the C-CCA and S-CCA groups. The outcomes of the C-CCA and S-CCA groups were mathematically compared and analysed. RESULTS: Our study demonstrates the clinical implications and the survival outcomes of C-CCA and S-CCA. Among the patients with unilateral hepatolithiasis, the incidence rates of C-CCA and S-CCA were fairly similar (4.8% vs 4.5%, respectively, P = 0.906). However, for the patients with bilateral hepatolithiasis, the incidence rate of S-CCA (12.2%) was higher than that of C-CCA (4.7%), although the sample size was limited and the difference between two groups was not statistically significant (P = 0.211). The average follow-up time was 56 mo for the C-CCA group and 71 mo for the S-CCA group. Regard to the average time intervals from operation to CCA diagnosis, S-CCA was diagnosed after 67 mo from the initial hepatectomy. The average time intervals from the diagnoses of CCA to disease-related death was 41 mo for the C-CCA group and 4 mo for the S-CCA group, this difference approached statistical significance (P = 0.075). Regarding the rates of overall and disease-related mortality, the C-CCA group had significantly lower overall mortality (70% vs 100%, P = 0.041) and disease-related mortality (60% vs 100%, P = 0.015) than the S-CCA group. For the survival outcomes of two groups, the Kaplan-Meier curves corresponding to each group also demonstrated better survival outcomes for the C-CCA group (log rank P = 0.005). In the C-CCA group, three patients were still alive at the time of data analysis, all of them had free surgical margins and did not have pathologically proven lymph node metastasis at the time of the initial hepatectomy. In the S-CCA group, only one patient had chance to undergo a second hepatectomy, and all 12 S-CCA patients had died at the time of data analysis. CONCLUSION: C-CCA has better outcomes than S-CCA. The first hepatectomy is crucial because most patients with recurrent CCA or S-CCA are not eligible for repeated surgical intervention.

[Ab] Abstract:PURPOSE: Urinary pH is an important factor linked to renal stone disease and a useful marker in the treatment of urolithiasis. Although the gold standard for measuring urinary pH utilizes a glass electrode and a pH meter, at present dipstick testing is largely used to estimate urinary pH. However, the accuracy and precision of this method may be insufficient for making clinical decisions in patients with lithiasis. The aim of this study is to describe a new device for urinary pH testing. METHODS: The device includes a pH sensor based on differential measurement of an ISFET-REFET pair. The drawbacks associated with this type of configuration, namely short lifetime and manual fabrication, have been overcome in the prototype. An automatic one point calibration is performed when turning on the system. Two buffer solutions were utilized to determine the intra- and inter-day precision of the device. The pH of 30 fresh human urine samples was measured using a pH-meter, a dipstick and the new electronic device. RESULTS: In some cases, dipstick measurements differed from those of the pH meter by more than 0.40 units, a clinically relevant discrepancy, whereas none of the measurements made with the new electronic device differed from the results of the pH-meter by more than 0.1 pH units. CONCLUSIONS: This new electronic device has the possibility to be used by stone-formers to control their urinary pH at home, increasing the tools available for stone prevention and prophylaxis.

[Ab] Abstract:OBJECTIVE: To compare the efficacy and safety of using 2 commercially available, low-magnesium, urine-acidifying dry foods to dissolve sterile struvite uroliths in cats. DESIGN: Prospective, multicenter, randomized clinical trial . SAMPLE: 37 cats with presumed struvite uroliths. PROCEDURES: Cats were randomly assigned to be fed 1 of 2 low-magnesium, urine-acidifying dry foods (food A or B). For each cat, physical examination, urinalysis, and abdominal radiography were performed weekly to assess treatment response. RESULTS: 32 cats had complete urolith dissolution. Mean ± SD times for a 50% reduction in urolith size (0.69 ± 0.1 weeks) and complete urolith dissolution (13.0 ± 2.6 days) were significantly shorter for cats fed food A, compared with those (1.75 ± 0.27 weeks and 27.0 ± 2.6 days, respectively) for cats fed food B. At study termination, mean ± SD urine pH (6.083 ± 0.105) for cats fed food A was lower than that (6.431 ± 0.109) for cats fed food B. In 5 cats, uroliths did not dissolve and were subsequently determined to be composed of 100% ammonium urate (n = 4) or 100% calcium oxalate (1). Adverse events associated with diet were not observed in any of the cats. CONCLUSIONS AND CLINICAL RELEVANCE: Results indicated that dietary dissolution is safe and effective for eradication of sterile struvite uroliths in cats. Cats fed food A had faster urolith dissolution than did cats fed food B. Lack of a reduction in urolith size at 2 weeks after diet initiation was indicative of misdiagnosis or noncompliance.

[Ab] Abstract:Salivary lithiasis is more frequently encountered in patients with Wharton's duct. They are often treated with a minimally invasive technique, such as sialendoscopy. The problem with sialendoscopy, in some cases, has been that it will not be possible to cannulate the papilla and, thus, sialendoscopy will not be feasible. Therefore, we have developed and detailed a retropapillary approach to cannulate Wharton's duct in such cases.

[Ab] Abstract:BACKGROUND/AIMS: Acute pancreatitis (AP) evades an etiological diagnosis in up to 10 % to 30 % of patients. This group, ie. idiopathic acute pancreatitis (IAP) is prone to a high recurrence (up to 70 %). Endoscopic ultrasound (EUS) is promising, but there is limited data on elucidating the cause of IAP, from India. This observational study was designed to study the role of EUS after the first episode of IAP. METHODS: All patients diagnosed to have first episode of IAP were included in the study and taken up for EUS examination after 6 weeks. Patients with conditions known to predispose or precipitate AP, like alcohol binge, drugs, metabolic or autoimmune conditions, or even a positive family history, were excluded from the study. RESULT: A total of 51 patients were included. EUS positivity was found in 29 (56.9 %) patients. It included common bile duct (CBD) calculus in 5 (9.8 %), CBD sludge in 4 (7.8 %), gallbladder calculus in 2 (3.9 %), gallbladder sludge in 2 (3.9 %), and chronic pancreatitis (CP) in 16 (31.4 %) patients. Fourteen patients had a normal study and eight patients had indeterminate CP. CONCLUSIONS: EUS is safe and has a reasonable diagnostic yield in patients with first episode of IAP. CP and biliary lithiasis are the most frequent positive findings on EUS. EUS should be included in the diagnostic protocol after the first episode of IAP, rather than waiting for recurrent episodes.

[Ab] Abstract:BACKGROUND: Urolithiasis during pregnancy is not common but remains both a diagnostic and treatment challenge. The aim of the study was to assess the ureteroscopy results as definitive treatment option in pregnant women with obstructive ureteral calculi. MATERIAL METHODS: Between 2006 and 2012, in our clinical department, 54 pregnant women underwent active treatment for ureteral lithiasis and in 38 of these cases ureteroscopy was applied as definitive therapy. The average patients age was 27.2 years (range 20-37 years) and the gestation period varied between 9 to 35 weeks. Flank pain was the common presenting symptom (52 54 cases), 4 women had associated fever, and 14 complained of irritative voiding symptoms.Semirigid ureteroscopy was the first choice alternative for the first 2 trimesters while flexible approach or double J in dwelling were preferred for patients in the last trimester of pregnancy. RESULTS: Semirigid ureteroscopy allowed stone treatment in 28 32 cases. In 17 patients, calculi fragmentation using Ho:YAG laser or ballistic lithotripsy were performed, while in 11 cases, the stone was removed intact. Minor intraoperative complications were encountered in 5 patients. Postoperatively,urinary tract infection developed in 4 patients, renal colic in 2 and prolonged hematuria in one case, while 4 patients complained of stent-induced bladder irritation. Flexible ureteroscopy was successfully completed in all patients. There were no complications related to this procedure. All pregnancies were carried out to full term. CONCLUSIONS: Ureteroscopy may be considered a safe and effective first-line definitive therapeutic option in pregnant patients requiring intervention for ureteral stone.

[Ab] Abstract:INTRODUCTION: Postoperative common bile duct (CBD) lithiasis holds a significant place in the bilio-pancreatic pathology, both due to its high frequency as well as to the diagnostic and treatment issues it triggers. MATERIAL AND METHODS: Based on a 5-year experience (2008-2012), assessed retrospectively, totalling 51 patients with postoperative lithiasis of CBD, we tried to elaborate on several recommendations for the treatment of this pathology. The recommendations were guided by the existing alternative therapeutic options and by the ideas in the literature regarding the results achieved by every manner of treatment. RESULTS: The rate of clearance of the CBD was of 93.6%,the morbidity rate was of 10.65% and the mortality rate was of 0%, which entitles us to deem the effectiveness of the minimally invasive treatment as maximum in the treatment of this pathology. CONCLUSIONS: The endoscopic treatment of postoperative lithiasis of the CBD proved to be possible, efficient and we believe it good to be used as a principle; open surgery should be the solution in case of failures or of contraindications to minimally invasive treatment.
