Retroperitoneal fibrosis as a cause of hypertension in an aviator: a case report.

The authors describe a case report of a previously healthy rotary-wing aviator who developed hypertension of unknown etiology. His 30 pack/year smoking history and hypercholesterolemia (ranging from 224-268) were significant. The initial evaluation revealed an elevated creatinine of 1.7 (normal to 1.5). Right-sided hydronephrosis was noted on ultrasound and the right kidney was poorly visualized on IVP. A subsequent retrograde cystoureterogram confirmed the hydronephrosis and demonstrated a distal calculus and stenosis, findings which were compatible with retroperitoneal fibrosis (RPF). This diagnosis was confirmed at surgery and the patient's ureters were freed. Following surgery, return of normal kidney function and satisfactory recovery, this aviator returned to full flying duty. A review of RPF is included.
