Change in circadian rhythm of blood pressure by bilateral radical nephrectomy and haemodialysis: a case report

It is well known that in patients with chronic kidney diseases, the nocturnal fall of blood pressure (BP) is lost and they manifest as nondippers.(1) In patients on haemodialysis (HD), it is also well known that nocturnal decline in BP is diminished,(2) although the related mechanism remains controversial. We report a patient who was performed bilateral radical nephrectomy for multiple and bilateral renal cell carcinoma. His circadian BP rhythms were changed after bilateral radical nephrectomy and/or HD.
