Administration of a mixture of 0.75% ethylene glycol and 2% ammonium chloride resulted in hyperoxaluria as well as increased renal excretion of calcium and phosphate. The decrease in the serum calcium concentration indicates an increased calcium oxalate formation. Supplementation of aqueous extract of H. sabdariffa at different doses (250, 500 and 750 mg/kg body weight) significantly lowered the deposition of stone-forming constituents in the kidneys and serum of urolithiatic rats. These findings have been confirmed through histological investigations. Results of in vivo genotoxicity testing showed no significant chromosomal aberrations in the bone marrow cells of ethylene glycol-induced rats. The plant extracts at the doses investigated induced neither toxic nor lethal effects and are safe. It can be concluded that the calyces of H. sabdariffa are endowed with anti-urolithiatic activity and do not have genotoxic effects. Thus, it can be introduced in clinical practices and medicine in the form of orally administered syrup after further investigations and clinical trials.","PeriodicalId":23412,"journal":{"name":"Urological Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1007/s00240-011-0433-3","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"40132316","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study was designed as a prospective, double blind randomized controlled trial. A total of 191 adult patients with radiolucent distal ureteral calculi were recruited. We included patients with solitary stones ≥5 mm with mild or moderate hydronephrosis and a normal contralateral tract. The patients were randomized into four equal groups (the placebo, tamsulosin, Uralyt-U(®), and the combined treatment groups). The patients were treated for a maximum duration of 4 weeks or until stone expulsion. The stone size in all groups ranged from 5 to 11 mm (7.69 ± 1.7 mm). The total expulsion rate of the stones was significantly lower in the control group (26.1%) compared with that of any of the other three groups (68.8, 58.7, and 84.8% respectively) (P < 0.05). Meanwhile, the difference between the Uralyt-U(®) group and the combined treatment group was also statistically significant (P < 0.05). When we studied the patients with stones >8 mm as a separate subgroup to find the effect of the used drugs on the relatively large stones, we detected that the expulsion rate of these stones was significantly higher in the patients who received the combined treatment in comparison with any of the other three groups (P < 0.05). In conclusion, the use of urinary alkalization with tamsulosin can increase the frequency of spontaneous passage of distal ureteral uric acid stones especially those of 8-11 mm.","PeriodicalId":23412,"journal":{"name":"Urological Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1007/s00240-011-0406-6","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"30091261","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Participants were interviewed face-to-face by medical faculty students. Participants with a history of urolithiasis (Group 1) were compared with participants without a history of urolithiasis (Group 2) in terms of hypertension, diabetes, body-mass index (BMI), waist size, and trouser size using Chi-square and odds ratio tests. Of the 2,468 participants, 274 (11.1%) reported a history of urinary stone disease diagnosed by a physician. The percentage of participants with hypertension along with urolithiasis was significantly higher than that in participants without urolithiasis (16.9 and 34.3%, p 0.000, OR 3.0). The percentage of participants with diabetes in groups 1 and 2 was 14.2 and 9%, respectively (p 0.001, OR 1.83). The mean BMI was 27.2 and 25.2, respectively (p 0.01).

Between September 2004 and October 2009, 18 children (19 renal units) underwent percutaneous nephrolithotomy using adult-type instruments. Following percutaneous access under fluoroscopy, 20-30F tract dilatation was performed (1,92,427F), and lithotripters were used. Postoperatively, kidney-ureter-bladder X-ray and antegrade pyelography were performed to evaluate residual stones and contrast passage to the bladder. 8 boys and 10 girls with a mean age of 9.8 ± 4.56 years were evaluated. Mean stone burden was 338 ± 196.21 mm². Stones were located in the left and right kidneys in 16 (84.2%) and 3 (16.8%) patients, respectively. Horse-shoe kidney was present in one patient. Mean operation (including cystoscopy) and fluoroscopy times were 106 ± 49.60 and 5.2 ± 2.14 min, respectively. Postoperatively, 10(52.6%) patients were stone free and 4 (21.1%) patients had clinically insignificant stones. Saline extravasation developed in three patients and surgery was aborted in one patient. Stone fragments migrated into the ureter in two patients and managed by additional endourological interventions. Nephrostomy catheters were kept for a mean of 2.6 ± 1.12 days. Four patients required blood transfusion due to bleeding. Postoperative fever of <39°C developed in five patients and >39°C in one patient. Mean hospitalization time was 5.3 ± 3.12 days. Overall, 73.7% of our patients were stone free, including patients with clinically insignificant stones. Particularly in children with a high-stone burden, the use of adult-type instruments might have a positive impact on stone-free rate, operation time and fluoroscopy time without increasing the complication rate.","PeriodicalId":23412,"journal":{"name":"Urological Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1007/s00240-011-0408-4","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"29911307","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of this study was to investigate the effect of proanthocyanidin on adherence of uropathogenic multi-drug resistant E. coli to uroepithelial cells, which has not yet been investigated so far. Extracts of the purified proanthocyanidin were prepared from dried cranberry juice. Purity and structural assignment of proanthocyanidin was assessed using high performance liquid chromatography and (13)C nuclear magnetic resonance spectroscopy, respectively. Subsequently, its affect on multi-drug resistant bacteria as well as quantification of anti-adherence bioactivity on human vaginal and bladder epithelial cells was appraised. Inhibition of adherence to an extent of about 70% with multi-drug resistant E. coli strains was observed on uroepithelial cell. The anti-adherence bioactivity of the proanthocyanidin was detected at concentrations of 10-50 µg/ml with significant bacteriuria. Probable proanthocyanidin through A-type linkages either combines to P-fimbriae of bacterial cells or modifies the structural entity of P-fimbriae and inhibits bacterial adherence to uroepithelial cells. The proanthocyanidin exhibited anti-adherence property with multi-drug resistant strains of uropathogenic P-fimbriated E. coli with in vitro study. Hence proanthocyanidin may be considered as an inhibitory agent for multi-drug resistant strains of E. coli adherence to uroepithelial cells.","PeriodicalId":23412,"journal":{"name":"Urological Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1007/s00240-011-0398-2","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"29948621","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
