I am a 75 year old fit and healthy woman with one kidney, as I donated the other one to my son 6 years ago. 2 weeks ago a routine kidney function test revealed an increase of creatinine levels to 185. I was referred to A and E where an ultra sound scan was performed, although my creatinine levels had returned to,80. I was thought to have a blockage of the tube between the kidney and bladder, which proved incorrect after a CT Scan, however I was diagnosed as having pelvicalyceal dilation and have been referred to the urology clinic on 20th October, can you enlighten me as to what this means please? I am passing urine regularly and do not have any discomfort I await your reply many thanks Marion Fry (Mrs)
