Blood pressure changes following extracorporeal shock wave lithotripsy in Kirkuk province

ABSTRACT

Hypertension has been reported as a possible sequela of extracorporeal shock wave lithotripsy. The aim was to determine, in a clinical trial, the effect of extracorporeal shock wave lithotripsy [ESWL] on blood pressure This study included 216 patients, aged [12-65] years, with asymptomatic renal stones that underwent ESWL in lithotripter unit/ Azadi teaching hospital -Kirkuk Province. Blood pressure was recorded randomly using a standardized protocol. Patients undergoing ESWL received a mean [+/- SD] of 3608.8 [+/- 475.9] shocks over a mean [6.81] of sessions on one lithotripter. Patients were then followed-up by assessing their blood pressure. Data were analyzed on an intention to treatment basis. At randomization [13.42]% of the study group were hypertensive. Of [320] patients referred to the study, [258] were recruited based on the inclusion and exclusion criteria. A total of [216] patients [83% of patients included] completed follow up, [137] [63.42%] were male and [79] [36.57%] were female. The mean follow-up period was [15.03] months. In the present study there was no association between mean diastolic and systolic blood pressure before and after ESWL. In the present study there was no evidence that ESWL causes changes in BP. More randomized control trials are needed to demonstrate the relationship between ESWL and hypertension
