The pain only lasted for about an hour but I then had what felt like a UTI so I went to the doctor. My urine tests came back fine but my doc requested ultrasound of my kidneys given my history. I went and got it done and received a call the following morning to go straight to ER that I had an abscess so I did (4.7cm). My urine and cbc both came back ok and didnt indicate any infection so they sent me home with order for another kidney ultrasound in two days. I got that done and it came back complex mass 5.7cm with recommendation for MRI that I cannot get done while pregnant. I have been told that its ok to wait these 4 months but I cant help but be terrified in the meantime. I have an appointment with urologist in 2 weeks. What am I really looking at here? On a scale of 1-10 how concerned should I be that this is cancer? Google is really scaring me. I plan to have MRI while in the hospital after I deliver. What can I anticipate at the urology appt? Any insight is greatly appreciated. Thank you for reading.. ### Response: Youll have to wait for the imaging study, but the wait shouldnt be a big deal. I prefer CT renal protocol over MRI, but maybe your urologist may feel differently. Based on the report its hard to say exactly whats going on. Theres no mention whether it is solid or not, which is critically important. Maybe just be a benign complex renal cyst. CT or MRI will clarify.Pelviectasis is minimal dilation of the renal pelvis. Based on your symptoms it sounds like you probably have a mild UPJ obstruction causing intermittent pain (Deidls crisis).Edit: spelling.
