Materials and Methods: We retrospectively reviewed the outcome of infant male circumcision (n=649) over 1 year (Jan 2021 to Feb 2022) performed under local anaesthesia by a single urologist. The technique was non-randomly selected. Data were collected retrospectively, and early postoperative complications were compared between Circumplast ® and Plastibell ® circumcisions. Both parents consented to the procedure. The 24-telephone support and follow-up were provided if required. Results: All records of infants were reviewed with Circumplast ® circumcision (CC) n=302 and Plastibell ® circumcision (PC) n=347 during this period. The mean age was 52.33 +/- 44.16 days in CC and 38.64 ± SD 30.39 days in PC. Three infants were excluded. There was no major complication and minor complications were lower in CC (0.99% n=3/302) versus PC (2.9% n=10/347). Delayed ring separation happened in PC (2.3% n=8/347), which was separated by a bone cutter in the clinic and no ring impaction occurred in CC. One infant in CC had bleeding after 24 hours, which was managed by removal of the ring and revision of circumcision. Two infants required separation of coronal adhesions in CC and two required revisions of circumcision in PC. Discussion: This is the first study to report the results of early experience involving the use of Circumplast ® ring to perform pediatric circumcision. Our findings reflect the use of this device as a safe alternative to Plastibell ® . A randomised controlled trial (RCT) would be required to document the relative superiority of either device. The reduced number of ring impactions among CC may be attributed to its unique design. Conclusion: Infant male circumcision by the Circumplast ® device has a lower risk of early postoperative minor complications especially migration/impaction and may offer a safe alternative.","PeriodicalId":38952,"journal":{"name":"Open Urology and Nephrology Journal","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135666956","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}

There is little information available regarding the prognostic factors of HD, its population characteristics, or outcomes in India. Objectives: We attempted to describe the profile of patients on HD, estimate the mean days of their survival and to determine the various factors associated with their survival. Materials and Methods: It was a retrospective cohort study conducted on patients who were on maintenance HD, registered during the five-year period between 1 st January 2014 and 31 st December 2018 in a tertiary care teaching hospital in Rural Puducherry, South India. Demographic, hematological, biochemical, electrocardiographic, echocardiographic parameters and death during follow-up were extracted from the dialysis database after de-identification. The survival rate was calculated using Kaplan- Meir Curves and Cox Regression analysis was done to estimate the adjusted hazard ratio. Results: The median survival of the 229 eligible patients on HD was 819 days. Cardiac pathology accounted for 25.7% of those deaths and 33.9% was sudden death. Adjusted Cox proportional model showed the presence of Left Ventricular Hypertrophy (LVH) (HR: 78.1), increase in phosphorus (HR: 1.26), decrease in haemoglobin (HR: 0.78), and decrease in serum albumin (HR: 0.52) were significant bad prognostic factors. Conclusion: Screening for LVH, anemia, hypoaluminemia and hyperphosphatemia amongst HD patients and managing them to prevent these bad prognostic factors has the potential to improve their survival.","PeriodicalId":38952,"journal":{"name":"Open Urology and Nephrology Journal","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135902698","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}

Bioimpedance has been used to estimate fluid volumes with three different methods of analysis:1. single-frequency; 2. multi-frequency; 3. bioimpedance spectroscopy. The aim of this study is to assess the accuracy of different types of bioimpedance analysis in detecting changes in fluid volumes. Methods Prospective observational study, in end-stage renal disease patients requiring dialysis, in a tertiary care center. During hemodialysis, we assessed the correlation between change in estimated total body water volumes, as measured by all three methods of bioimpedance, and fluid volumes removed, as measured by changes in body weight. Results Twenty-four pediatric and adult patients were included in the study (median age 42.4 years) with a total of 30 study assessments performed. There was a weak correlation between change in body weight and change in estimated total body water volumes (R=0.15, 0.41, and 0.38, respectively). In the Bland-Altman analysis, the mean biases along with their associated 95% confidence limits of agreement were -0.23 L (-4.1 to 3.5 L) for single-frequency; -1.1 L (-4.1 to 1.9 L) for multi-frequency; and -0.6 L (-6.1 to 4.8 L) for bioimpedance spectroscopy.

To date, there has not been a consistent therapeutic approach to manage aAMR. The aim of the study is to evaluate the tolerance and efficacy of an institutional protocol of methylprednisolone, intravenous gamma globulin (IVIG), rituximab, and bortezomib used to treat aAMR in pediatric renal transplant recipients (pRTRs). Methods A retrospective chart review was performed on 10 pediatric renal transplant recipients (pRTRs) who were diagnosed with aAMR on a renal biopsy performed between January 2014 and November 2015. Results Over the study period, 9.5% of pRTRs had aAMR. Sixty percent of whom had concurrent acute cellular rejection (ACR). Renal allografts survival was 100% during the the first post-aAMR. At the time of diagnosis of aAMR, estimated glomerular filtration rate (eGFR) had decreased by 42% (mean at baseline eGFR=67.2±19.5 mL/min/1.73 m2 vs mean at aAMR eGFR=38.9±14.2 mL/min/1.73 m2; p=0.002). At 1-year post rejection, eGFR had increased by 26% as compared eGFR at the time of rejection (mean eGFR=49.0±13.2 mL/min/1.73 m2; p=0.006). Immuno-dominant donor-specific anti-HLA antibody titers (iDSAs) class I and class II decreased by 69% and 15% at 6-month follow-up visit. No serious opportunistic infections nor malignancy were reported in our subjects. Conclusion Our study suggests that our protocol improved kidney function with 100% graft survival at 1-year post aAMR episode. The percentage decline in iDSAs class I titers was more significant than class II. Furthermore, our treatment protocol was well-tolerated with no life threatening complications.","PeriodicalId":38952,"journal":{"name":"Open Urology and Nephrology Journal","volume":"32 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81876865","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}

It is recommended that non-muscle invasive bladder cancers (NMIBC) should be treated with transurethral resection of the bladder tumor (TURBT) followed by chemotherapy. However, there is no large-scale study from real-world databases to show the effectiveness of chemotherapy on the survival of older adults with NMIBC that have undergone TURBT. This study aimed to investigate the effects of chemotherapy on survival among older NMIBC patients with TURBT. Methods: Using the Surveillance, Epidemiology, and End Results (SEER) database (2010-2015), we performed analyses of cancer-specific mortality and overall mortality comparing chemotherapy versus no chemotherapy after TURBT. Coarsened exact matching was performed to balance the baseline patient characteristics. Cox proportional hazards and Kaplan-Meir analyses were used to evaluate survival outcomes. Results: A total of 3,222 matched patients with 1,611 in each arm (chemotherapy and no chemotherapy) were included in our study. After adjusting for covariates, multivariable Cox regression analyses show chemotherapy was associated with lower cancer-specific mortality (HR 0.63; 95% CI 0.42-0.94; p value 0.024). However, chemotherapy did not have any effect on overall mortality (HR 0.84; 95% CI 0.65-1.07; p value 0.159). The Kaplan-Meier curves show the protective effects of chemotherapy on cancer specific survival (p=0.032), but not on overall survival (p=0.34). Conclusion: Chemotherapy improved cancer specific survival among older patients with non-muscle invasive bladder cancer undergoing TURBT surgery, but it had no effect on overall survival. There is a need for more granular level real-world data on chemotherapy regimens and dosage to effectively investigate the effects of chemotherapy on survival of older patients with NMIBC that have undergone TURBT.","PeriodicalId":38952,"journal":{"name":"Open Urology and Nephrology Journal","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47850974","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}
