“…However, another cross-sectional cohort study showed that there was no significant difference in BP among RCC patients who underwent RN ( 69 ). Besides, the circadian rhythm of BP may also be affected after bilateral RN ( 74 ).…”

Advances in tumor diagnosis and treatment, especially the use of targeted therapies, have remarkably improved the survival rate of patients with renal cell carcinoma (RCC), accompanied by higher hypertension (HTN) incidence among patients with RCC, reflecting the coming of a cardio-oncologic era. Therefore, for patients with RCC and HTN simultaneously, finding risk factors for the comorbidity and giving better clinical treatment have been urgent problems. In this review, we thoroughly investigated risk factors for the comorbidity of HTN and RCC based on preclinical and clinical studies. Firstly, RCC and HTN may have common risk factors, such as obesity, smoking, and other modifiable lifestyles. Secondly, RCC and HTN may lead to each other directly or indirectly by their therapies. We then discussed measures of reducing the comorbidity and treatment of HTN in patients with RCC. We also discussed the deficiency of current studies and pointed out future directions. In conclusion, this review aims to deepen the understanding of cardio-oncology and bring benefit to the population who are at high risk of getting or have already got RCC and HTN simultaneously.

“…Uzu et al demonstrated the importance of either or both the fluid status or kidneys in the genesis of the diurnal BP rhythm ( 13 ). We did not perform any image assessments such as evaluating the cardiotracic rate or diameter of the inferior vena cava before and after nephrectomy in the present study.…”

“…These authors detected an increase in the postoperative daytime BP, and while the postoperative nighttime BP measured after the HD session was unchanged, the postoperative nighttime BP before the HD session was elevated compared with the values before the operation. Given these results, the authors concluded the importance of either or both the fluid status or kidneys in the genesis of the diurnal BP rhythm ( 13 ).…”

The Effects of Unilateral Nephrectomy on Blood Pressure and Its Circadian Rhythm

et al. 2016

Objective Hypertension and diurnal blood pressure (BP) variation are widely accepted as risk factors for renal damage. However, the effects of unilateral nephrectomy on BP and its circadian rhythm have not yet been clarified in patients with a compromised renal function, including dialysis patients. Methods We investigated 22 unilateral nephrectomized patients (16 men and 6 women, age: 64.5±14.3 years). The function of the circulating renin-angiotensin system (RAS) (plasma renin activity and plasma angiotensin II) and 24-h ambulatory BP monitoring (ABPM) were evaluated before and after nephrectomy. Daytime and nighttime 24-h ABPM values were determined based on sleep and waking times. Results In non-dialysis patients, the estimated glomerular filtration rate after nephrectomy was significantly lower than that before (before, 62.4±23.2 mL/min/1.73 m2 vs. after, 43.7±16.8 mL/min/1.73 m2; p<0.01). No significant differences were noted in the levels of BPs and circulating RAS before and after nephrectomy. However, the night-to-day (N/D) ratio of systolic BP (SBP) was significantly higher after nephrectomy than before (before, 93.3±6.5% vs. after, 98.4±6.9%; p<0.01), and the patterns of circadian BP rhythm also significantly differed before and after nephrectomy (p=0.022). Namely, the rates of dipper patterns decreased and nondipper and riser patterns increased after nephrectomy. In contrast, in dialysis patients, no significant differences were observed in the N/D ratio of SBP or the patterns of circadian BP rhythm before and after nephrectomy. Conclusion Unilateral nephrectomy affects the circadian rhythm of BP but not absolute values of BP.
