My Wife recently had an episode of ?PID - after first consultation suspected a kidney/bladder infection, after blood and urine tests she was admitted to hospital with severe R) flank pain and CRP 140,Urine MCS negative and renal US normal. Cervical motion tenderness (apparently?) and mild vaginal discharge (apparently?). She was treated with IV Abx for suspected PID? with improvement and now not in any pain . She had a similar episode in 2015 which settled down after a few days without any antibiotics and US normal. Pelvic US post admission has shown a left hydrosalpinx and R) 21 mm endometrioma. Background: occasional intermenstrual pelvic pain for last few years. Previous papsmear in 2015 normal. ULTRASOUND PELVIS AND RENAL Sept/2016 PELVIC AND RENAL, ULTRASOUND Summary complex adnexal appearances. There is hydrosalpinx on the 1eft. Two hypoechoic focj possibly reflecting endometriomata- patient was not overly tender in this region to suggest tubo-ovarian abscess, although if patient has been treated previously this may reflect some residual chanqe. Appearance on the riqht side suqqestive of a 21m endomertriomata. clinical: Right flank pain treated for ?pyelonephritis ?PID. Transabdominal and transvaginal scanning performed. Kidneys: Right 11.9cm, left 12.1cm in bipolar length. No hydronephrosis. No renal cortical scarring, or gross collection seen. vascularity appears symmetric Bladder: Pre-void bladder volume 161.ccs. No disral ureteric dilatation., No mucosal lesion. There is a non-significant post void residual of 17ccs_ Uterus: Retroverted 91x44x47mm. Endometrial thickness satisfactory at 7mm. Myometrim qenerally heterogenous, but with discrete lesion. Ovaries: Right ovary 7ccs in volume. There is a 21m hypoechoic focus exophytic from the riqht ovary which contains low level echoes, and is suggestive of an endometriomata. There is a conplex appearance in the left adnexa.
