<s>[INST] I am having right side pain in front and back and very high blood pressure, fluid retention, fatigue shortness of breath. I have a history of hi blood pressure usually controlled by medications, and cystinuria (cystine stones) for 35 years. I went to er had ct without contrast they didnt see a stone but the left kidney showed irregular contour of inferior pole other wise urine and blood work were fine although blood pressure 185/105 when i left after 4mg morphine. I am a 52 yr old female. [/INST] Hello,Is it a mass or kidney itself showing irregular contour? Possible causes are:1. Polycystic kidney.2. Renal malignancy.3. Inf pole infraction.4. Post nephritis changes.Until examination is done it is difficult to say what it is. Please consult with your nephrologist he will examine and treat you accordingly.Take care. Hope I have answered your question. Let me know if I can assist you further. Regards, Dr. Penchila Prasad Kandikattu, Internal Medicine Specialist </s>
