[Ab] Abstract:Hepatobiliary ultrasound was carried out on 2224 consecutive patients at the Center for Nuclear Medicine and Ultrasound and at one private diagnostic center in Mymensingh for ultrasound examination of different systems. The purpose of this study was to investigate the prevalence of biliary ascariasis and its association with other biliary diseases, specially biliary lithiasis. Data regarding the presence of stone, worm or other diseases were recorded accordingly in this prospective study. There were 952 male and 1272 female patients with an age range of 5-90 years. Biliary diseases were detected in 305 patients (13.71%), of whom 97 were male (10.19%) and 208 were female (16.35%). The most common biliary disease in both sexes was cholelithiasis (11.87%), which was found in 84 male patients (8.82%) and in 180 female patients (14.15%). Other diseases found were choledocholithiasis in 14 patients (3 males, 11 females), gall bladder mass in 9 patients (3 males, 6 females), common bile duct mass in 7 patients (4 male, 3 female) and biliary ascariasis in 10 patients (3 male, 7 female). Overall prevalence of biliary ascariasis was 0.45% (0.31% in male patients and 0.55% in female patients), and age range of patients with the condition was 6-50 years. No case of biliary ascariasis was associated with cholelithiasis or choledocholithiasis. Acute cholecystitis was associated with 8 cases (80%) of biliary ascariasis. Common sonographic findings in patients with biliary ascariasis were a single long, linear or curved echogenic structure within the bile duct, without acoustic shadowing. Other findings were gall bladder distention with sludge inside, an edematous wall and mildly dilated biliary tree. Prevalence of biliary ascariasis in the study was 0.45%, with incidence being higher in female subjects (0.55%). No correlation was found between biliary ascariasis and biliary lithiasis. Most of the cases of biliary ascariasis were associated with acute cholecystitis. We concluded that a careful search for biliary ascariasis should be considered for patients with acute acalculus cholecystitis, especially in areas in which ascariasis is endemic, such as Bangladesh.

[Ti] Title:Urine Stasis Predisposes to Urinary Tract Infection by an Opportunistic Uropathogen in the Megabladder (Mgb) Mouse.

[Ab] Abstract:PURPOSE: Urinary stasis is a risk factor for recurrent urinary tract infection (UTI). Homozygous mutant Megabladder (Mgb-/-) mice exhibit incomplete bladder emptying as a consequence of congenital detrusor aplasia. We hypothesize that this predisposes Mgb-/- mice to spontaneous and experimental UTI. METHODS: Mgb-/-, Mgb+/-, and wild-type female mice underwent serial ultrasound and urine cultures at 4, 6, and 8 weeks to detect spontaneous UTI. Urine bacterial isolates were analyzed by Gram stain and speciated. Bladder stones were analyzed by x-ray diffractometry. Bladders and kidneys were subject to histologic analysis. The pathogenicity of coagulase-negative Staphylococcus (CONS) isolated from Mgb-/- urine was tested by transurethral administration to culture-negative Mgb-/- or wild-type animals. The contribution of urinary stasis to CONS susceptibility was evaluated by cutaneous vesicostomy in Mgb-/- mice. RESULTS: Mgb-/- mice develop spontaneous bacteriuria (42%) and struvite bladder stones (31%) by 8 weeks, findings absent in Mgb+/- and wild-type controls. CONS was cultured as a solitary isolate from Mgb-/- bladder stones. Bladders and kidneys from mice with struvite stones exhibit mucosal injury, inflammation, and fibrosis. These pathologic features of cystitis and pyelonephritis are replicated by transurethral inoculation of CONS in culture-negative Mgb-/- females, whereas wild-type animals are less susceptible to CONS colonization and organ injury. Cutaneous vesicostomy prior to CONS inoculation significantly reduces the quantity of CONS recovered from Mgb-/- urine, bladders, and kidneys. CONCLUSIONS: CONS is an opportunistic uropathogen in the setting of urinary stasis, leading to enhanced UTI incidence and severity in Mgb-/- mice.

[Ab] Abstract:The addition of melamine to infant formula may cause urolithiasis in humans and animals. This study examined the effects of catechin, an antioxidant, on melamine-cyanuric acid mixture (MCM)-induced crystallization in vitro and in vivo. In an in vitro study, crystal formation induced by an MCM was evaluated in media under various pH conditions and with catechin co-treatment. In an in vivo study, rats were administered an MCM (400 mg/kg, 1:1, via oral feeding tube) for four weeks and co-treated with catechin, after which crystal formation was observed. Oxidative stress biomarkers and nephrotoxicity were measured. Apoptotic cells were examined using the TUNEL assay. Phospho-p38 and osteopontin were evaluated via immunohistochemistry and Western blotting. MCM-induced crystal formation was pH-dependent in conditioned media, and catechin reduced the overall number of crystals. In the in vivo study, catechin suppressed MCM-induced protein expression and apoptosis in rats. Catechin consistently reduced the MCM-mediated production of renal malondialdehyde (MDA) and urinary 8-isoprostane (8-IP) in MCM-treated rats. The activities of antioxidant enzymes such as superoxide dismutase (SOD) were enhanced by catechin. Catechin consistently and significantly reduced levels of renal crystals and nephrotoxicity. Our findings suggest that catechin exhibits anti-nephrolithic potential by chemically inhibiting the formation of crystals and by inhibiting reactive oxygen species, apoptosis, phospho-P38, and osteopontin signaling in rats.

[Ab] Abstract:Dual-energy computed tomography (DECT) is based on obtaining 2 data sets with different peak kilovoltages from the same anatomical region, and material decomposition based on attenuation differences at different energy levels. Several DECT technologies are available such as: the dual-source CT, the fast kilovoltage-switching method, and the sandwich detectors technique. Calculi are detectable using iodine subtraction techniques. DECT also helps characterization of renal stone composition. The advanced postprocessing application enables differentiation of various renal stone types. Calculation of water content using spectral imaging is useful to diagnose urinary obstruction.

[Ab] Abstract:INTRODUCTION: There is limited data about urolithiasis in young infants. We reviewed clinical, imaging, and biochemical data of urolithiasis in the first 2 months of life. MATERIALS AND METHODS: In an 11-year period, 77 of the 1172 children diagnosed with urolithiasis (6.8%) were 60 days old and younger (64.9% boys and 35.1% girls). Routine diagnostic assessments included urinalysis and urine culture; measurement of calcium, uric acid, oxalate, and creatinine in nonfasting random urine; measurement of blood urea nitrogen and serum creatinine, sodium, potassium, calcium, and phosphorus levels; and venous blood gasometry. Urinary calculi were diagnosed using tridimensional ultrasonography with 5-MHz, 7.5-Mhz, and 10-MHz probes. RESULTS: The most common symptom was irritability (37.6%). A family history of urinary calculi was documented in 49.4% of the patients. The calculi were 0.5 mm to 6 mm in length. Eight infants (10.4%) had urinary tract infection. Hypercalciuria was found in 21 of 62 patients (33.8%). There were no cases of hyperuricosuria, hyperoxaluria, or struvite calculus. Vesicoureteral reflux was reported in 9 of 20 patients who underwent voiding cystourethrography. Two-thirds of asymptomatic and 85% of symptomatic infants were diagnosed during summer and autumn, and the peaks of calculus visits were in September, October, and November. Of 43 infants (55.8%) who were followed up (Mean, 16.2 ± 15.2 months), none needed calculus removal interventions. CONCLUSIONS: Hypercalciuria is the most common urinary metabolic abnormality in young infants with urinary calculus. Infection was not an important factor for our cohort in the pathogenesis of the disease.

[Ab] Abstract:BACKGROUND AND PURPOSE: Many studies have been conducted to investigate adjunctive tamsulosin therapy after extracorporeal shockwave lithotripsy (SWL) for urolithiasis. The results from those studies, however, are still inconsistent. Therefore, we performed a meta-analysis to provide an update on the clinical efficacy and safety of tamsulosin combined with SWL for urolithiasis. METHODS: A systematic search was performed in PubMed, Cochrane Library, and Embase to identify all relevant randomized controlled trials until January 2015. Two reviewers independently assessed trial quality and extracted data. Meta-analysis was conducted with Review Manager (RevMan), version 5.1. RESULTS: Twenty-one studies (2093 subjects in total) were identified in the current meta-analysis. Compared with a control group, the experimental group (tamsulosin combined with SWL) showed an increased overall benefit for stone expulsion, with pooled risk ratio (RR) of 1.20 (95% confidence interval [CI], 1.15-1.26). With respect to the different geographic regions, European and American had a high possibility of improvement in stone expulsion (RR: 1.33, 95% CI, 1.19-1.49). According to the stone locations (renal, upper and lower ureteral) and sizes (4-10 mm and 11-24 mm), tamsulosin is more useful for lower ureteral stone (RR: 1.28; 95% CI, 1.14-1.43) and larger sized stones (RR: 1.49; 95% CI, 1.28-1.75). The effect estimates did not vary markedly when stratified by follow-up durations but varied by dose of tamsulosin. Furthermore, a shorter expulsion time, reduced occurrence of steinstrasse, fewer incidences of colic, and lower analgesic requirements were observed within the experimental group. In addition, tamsulosin is well tolerated, and its adverse events rarely led to dropouts of patients. CONCLUSIONS: Overall, evidence suggests that tamsulosin combined with SWL is safe and effective in enhancing stone expulsion for patients with urolithiasis. Furthermore, high-quality, randomized and placebo-controlled trials evaluating the efficacy and safety of tamsulosin should be performed.

[Ab] Abstract:PURPOSE: To describe the utilization of shockwave lithotripsy (SWL) and ureteroscopy (URS) in ambulatory surgery centers, as well as to identify patient-specific factors predictive of one procedure over the other. PATIENTS AND METHODS: We evaluated the current trends in the use of SWL and URS in the ambulatory settings over a 5-year period in the state of California using the State of California Office of Statewide Health Planning and Development (OSHPD) database. RESULTS: We identified 113,447 ambulatory kidney stone surgical procedures including 64,632 SWL (57%) and 48,815 URS (43%) treatments in the OSHPD database between 2005 and 2010. The total annual ambulatory stone surgeries increased from 17,831 cases in 2005 to 18,933 cases in 2010 (P<0.001). Between 2005 and 2010, the use of URS increased significantly from 6978 (39%) cases in 2005 to 9259 (49%) cases in 2010 (P<0.0012), whereas the use of SWL decreased from 10,853 (61%) cases in 2005 to 9674 (51%) cases in 2010 (P=0.0012). In multivariate analysis, age ≥ 75 years (P<0.001), hypertension (P=0.025), and obesity (P<0.001) all increased odds of undergoing URS. In addition, men (P=0.013) and non-Medicaid patients (P<0.001) were more likely to undergo URS. CONCLUSIONS: The use of URS increased significantly in the state of California among patients undergoing urinary stone surgical procedures in the ambulatory setting, while the use of SWL decreased between 2005 and 2010. Possible explanations for these trends include improved URS stone-free rates, improved cost-effectiveness of URS, and enhanced technology leading to increased use of URS over SWL.
