I have gone through the query in detail. Mildly enlarged kidney is not the likely cause for sudden rise in BP to 220 mm Hg. It needs detailed evaluation as a case of young onset hypertension.

Hello, as per my understanding based on the history you have provided , you have and obstructive nephropathy... the cause of obstruction needs to be evaluated . May be there is a chance that the obstruction can be relieved and your kidney can be preserved. If the obstruction is not treated in the long run you can loose you kidney function , land in a serious infection or other complication. Best will be if u can get a CT KUB and get a detailed evaluation. Yea the Blood pressure can be raised in this case , or this could be underlying hypertension which has been aggravated due to your current condition. You can consult me if u need any other help. I cannot comment on kidney removal at present as i donot have all the details. Thanks.
