Post Bariatric Surgery Acute Kidney Injury: Incidence and Risk Factors
An observational study of Bariatric Surgery and Acute Kidney Injury, run by Georgina Tharwat Abdelmasih.
Trial summary
Bariatric surgery is the most effective means of inducing and maintaining sustained weight loss. Apart from the weight loss effect, bariatric surgery leads to the remission of chronic metabolic disorders such as type 2 diabetes (T2D) and hypertension . Read more about this study

About this study
Bariatric surgery is the most effective means of inducing and maintaining sustained weight loss. Apart from the weight loss effect, bariatric surgery leads to the remission of chronic metabolic disorders such as type 2 diabetes (T2D) and hypertension . Recent studies have shown that bariatric surgery improves renal perfusion and glomerular function and reduces inflammatory markers which can lead to an improvement of microalbuminuria and proteinuria However, acute kidney injury (AKI) can complicate the postoperative course after bariatric surgery. The etiology of AKI after bariatric surgery can be multifactorial and complex in obese population . The preexisting factors such as diabetes, hypertension, and CKD in these patients can additionally worsen the renal insult during the postoperative period . Postoperative AKI is associated with increase morbidity and mortality especially in cases of severe AKI that requires dialysis support . Identifying the high-risk patients for development of postoperative AKI would prevent renal injury. Our aim was to study the incidence and etiology of postoperative AKI after bariatric surgery . Causes of post bariatric surgery AKI include . Pre renal causes :dehydration ( repeated vomiting and diarrhoea)which are common complications post bariatric surgery , haemorrhagic shock (from the site of anastomosis , ulcer ) , septic shock ( leakage , pneumonia) , hypotension and respiratory depression secondary to narcotic overdose. Rena causes: contract induced nephropathy after using CT scan guided drainage of intra abdominal collection post operative, Rhabdomylosis , drug induced nephropathy e.g :using of IV vancomycin for sepsis in ICU .. many causes can lead to AkI post bariatric surgery but the common two causes are dehydration and sepsis .

Questions about this trial
What is this clinical trial studying?
An observational study of Bariatric Surgery and Acute Kidney Injury, run by Georgina Tharwat Abdelmasih.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: opening soon, as of the sponsor's last update on 20 Nov 2024. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Georgina Tharwat Abdelmasih, Master (georginatharwat8@gmail.com ext. +20 1203254445, georginatharwat8@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
incidence (time frame: Baseline). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT06697743, which also lists 7 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 Nov 2024.
