Clinical Course: She had a BS degree in Computer Science and Engineering, and an MS degree in Information Technology (software track) from the (Institution Name Withheld). She moved from (City and State Withheld) to (City and State Withheld) in 2015 with her husband, (Name Withheld), PhD who was a tenured Associate Professor of Civil and Environmental Engineering at (university and state name). She was healthy and had no organ-related health issues prior to her COVID-19 vaccinations from Pfizer in 2021. Meanwhile, on 02Nov2022, she went to her yearly complete physical checkup and informed the doctor about having a frequent flank pain on right upper quadrant abdomen area for several months. Following doctor's suggestions, she then did an ultrasound for her upper right quadrant abdomen area. Based on report, she came to know from doctor that she had a significantly atrophic right kidney. She was shocked since she had heard the news for the first time in her life, despite having done many full abdominal ultrasounds and CT scans for other purposes (e.g., typhoid diagnosis in 2010, as well as two pregnancies during 2011-2012 and 2015-2016). The primary care doctor referred her to a Specialist Urologist soon. She was able to find an appointment with urologist as early as 06Mar2023. Subject to continuous flank pain and fever, she went to primary care again and did another ultrasound on 23Feb2023. Based on report, her doctor commented, "Her kidney ultrasound continued to show that her right kidney was very small." Her right kidney was measured to have dimensions of 7.3 cm x 3.4 cm at that time. She went to urologist and did another ultrasound on 04May2023. The result showed a shrinking right kidney, stating, "The right kidney was below normal in size measuring 6.8 cm in length." She was having severe and continuous symptoms such low-grade fever, fatigue, and right-side flank pain. She contacted her urologist again. Following suggestions from the urologist, I did a Nuclear Renal Scan and a CT Angio Abdomen on 01Jun2023. The CT Angio report "Atrophic right kidney with patent single right renal artery, which was correspondingly smaller than left renal artery." On a follow-up visit, her urologist explained, right kidney was significantly atrophic and poorly functioning; however, it was not obstructed and cannot improve its function. She was a mother of two kids (11years and 7 years). Both the delivery was normal, and the pregnancy period was also normal. She did many ultrasounds during her pregnancy time. She never had any issues at that time. She had no previous kidney injury. Now her life had become severely limited with a potentially uncertain and compromised future. She must survive with one kidney, which was a disability and a new dimension added to her life. She felt fatigued with low energy, which was significantly obstructing her daily life. Her life had become limited in so many ways. She was not able to stand for long, lift normal weights, or vacuum her house. Her dream career and job prospect had been significantly compromised by atrophic kidney and associated symptoms after taking the Pfizer vaccines. Her health had been severely damaged due to loss of a critical and vital organ. Her life expectancy had likely been significantly reduced by vaccines. She was extremely worried about herself, her underaged kids and her family. To save her remaining kidney, she must go through regular ultrasounds (and CT scan), lab works, and doctor's appointments (every 6 month). She was very concerned about her left kidney, which had been making up for lost function of her damaged right kidney. She was afraid that she may require a kidney transplant in the foreseeable future. She therefore requested Pfizer to provide her with a significant compensation for her lost kidney, continuous physical and mental sufferings, obstructed daily life and reduced life-expectancy, potential treatments, loss of career in a highly demanding field, and uncertain future for herself and her family, including her two underaged kids. Comments From the Doctor's Office: Her kidney ultrasound continued to show that her right kidney was very small. There were some changes in the kidney likely due to kidney infections that had. Otherwise the anatomy appears normal - no obvious reason for these kidney infections. The kidney also had good blood flow which was a good sign. CT. ABD Pelvis With Contrast: 16Jul2010 15:32: Technique: Limited images through lung bases demonstrate no pleural or pericardial effusions. Heart size was normal. No focal areas of consolidation or mass were present. Since last examination, the bowel wall thickening involving right hemicolon had resolved. Thickening of terminal ileum had improved, although it was still somewhat dilated and remains fluid-filled. No localized abscess formation was present. No bowel obstruction had developed. No enlarged lymph nodes had developed within abdomen or pelvis since examination. Kidneys were not obstructed. Spleen was not enlarged. There were no CT changes of pancreatitis. Changes compatible with focal fatty infiltration of liver near the falciform ligament were stable. Bladder outline was unremarkable. No adnexal masses were present. Ischiorectal fossa was unremarkable. Bone windows demonstrate no abnormalities. CT Angio Abdomen W IV Contrast on 01Jun2023 04:08 PM: Technique: Axial images from lung bases through upper thighs followed by intravenous administration of nonionic contrast, with additional multiplanar images in early arterial and venous phases. Arterial coronal and sagittal reformats utilize MIP reconstruction techniques. Patient pregnant: Possibly (Pregnancy test needed).; Sender's Comments: Linked Report(s) : US-PFIZER INC-PV202300135086 same patient/product, different dose (dose 3)/event;
