Write answer in between .Q:A 66-year-old G3P3 presents with an 8-year-history of back pain, perineal discomfort, difficulty urinating, recurrent malaise, and low-grade fevers. These symptoms have recurred regularly for the past 56 years. She also says that there are times when she experiences a feeling of having a foreign body in her vagina. With the onset of symptoms, she was evaluated by a physician who prescribed her medications after a thorough examination and recommended a vaginal pessary, but she was non-compliant. She had 3 vaginal deliveries She has been menopausal since 51 years of age. She does not have a history of malignancies or cardiovascular disease. She has type 2 diabetes mellitus that is controlled with diet and metformin. Her vital signs include: blood pressure 11060 mm Hg, heart rate 91min, respiratory rate 13min, and temperature 37.4C 99.3F. On physical examination, there is bilateral costovertebral angle tenderness. The urinary bladder is non-palpable. The gynecologic examination reveals descent of the cervix to the level of the introitus. A Valsalva maneuver elicits uterine procidentia. Which pathology is most likely to be revealed by imaging in this patient?? A: Renal tumor, B: Hydronephrosis, C: Urinary bladder polyp, D: Renal calculi, E: Renal cyst,  <response>: Based on the patients age, symptoms of back pain, perineal discomfort, difficulty urinating, recurrent malaise, low-grade fevers, and feeling of foreign body in vagina, along with history of 3 vaginal deliveries, menopause at 51, and physical exam finding of uterine procidentia with Valsalva, this clinical presentation is most consistent with pelvic organ prolapse. The chronic symptoms over 8 years and intermittent nature point towards a mechanicalanatomical disorder rather than an infectious or inflammatory process. The lack of cardiovascular disease or malignancy history makes those etiologies less likely.Imaging would be expected to show pelvic organ prolapse involving the uterus, bladder, rectum or small bowel. Renal or bladder masses are not likely based on the clinical picture.B: Hydronephrosis
