The Blood Pressure After Percutaneous Nephrolithotomy
Hypertension has been identified in patients following extracorporeal shock-wave lithotripsy (ESWL) (1). To determine whether the prevalence of hypertension after ESWL is different from that after other forms of treatment, we have reviewed the pre-operative and post-operative blood pressures in 190 of 207 consecutive patients who underwent percutaneous nephrolithotomy between 1983 and 1987. Of the 17 patients who were not reviewed, five have died of causes unrelated to hypertension, and 12 could not be contacted. The follow-up duration ranged from 12 to 49 months. We defined hypertension as a systolic blood pressure greater than or equal to 140 mm Hg, and a diastolic blood pressure greater than or equal to 90 mm Hg (2).
