Prospective and retrospective evaluation of blood pressure changes in patients treated by ESWL for renal stones

ABSTRACT

Forty-four patients were followed prospectively to detect the stepwise alteration in their blood pressure after ESWL. Further 181 patients, previously treated by ESWL for renal stones, were reevaluated after an average period of 20.3 months [range 6-40 months]to evaluate long term effect of ESWL on their blood pressure. Significant elevation of both systolic and diastolic pressures was found in the majority of patients, most marked, 24 hours after treatment sessions to decrease gradually over the following three months. The annual rise of systolic and diastolic pressures in treated patients was estimated to be 1.1 and 1.4 mmHg, respectively, and new onset of hypertension was calculated to be 4.07% with annual incidence of 3.9%. Changes of diastolic pressure appeared earlier and were statistically more significant than changes of the systolic pressure
