Introduction:

The aim of the study compare standard blood pressure (BP) measurement and ambulatory BP measurement (ABPM) and necessity of ABPM in children with bilateral renal scarring.

Material and methods:

The study was included 79 patients having bilateral renal scarring due to urological reasons. All renal scars were diagnosed using by DMSA. Serum and urine biochemical parameters of patients were recorded. For standard BP measurements, average of last three BP values were taken after rest. Standard deviation score (SDS) data were used according to LMS method for ABPM values. All cases were examined for the presence of end organ damage of HT.

Results:

There were 79 patients; 35 males (44.3%) and 44 females (55.7%) with the mean age of 12.3±4.0 years. Only 6 (7.6%) patients were HT according to standard BP measurements. On the other hand, 28 cases (35.5%) were found hypertensive by ABPM (masked HT). The difference between standard BP and ABPM measurements of patients were statistically significant (p< 0.001). ABPM data were showed the 3.8% of white coat HT and 31.6% of masked HT. Among the masked HT cases 10 of them (37%) had proteinuria, 6 of them (27.2%) had microalbuminuria. There were mild correlations with GFR and ABPM values in HT group. Average GFR values of hypertensive patients are lower than that of normotensive patients (p=0.024). Daytime and daily systolic BP SDS were found higher in patients with microalbuminuria (p=0.020 and 0.049 respectively).

Conclusions:

High BP is major problem in patients with renal scarring. Controlling high BP and early diagnosis, also treatment is very significant to protect these patients against to end-organ damage. Our study supported that standard BP measurement technique was not enough for diagnosis of HT in bilateral renal scarring patients.
