Symptomatic urogenital manifestations of polyarteritis nodosa and Churg-Strauss angiitis: analysis of 8 of 165 patients.

To establish the clinical features and evolution of ureteral and testicular manifestations of polyarteritis nodosa, 8 cases among a group of 165 patients were reviewed. Urogenital manifestations are rare and were related to hepatitis B virus markers in 5 of the 8 patients. Malignant hypertension was present in 6 of 8 patients and renal insufficiency related to renal infarctions was noted in 5. Prognosis is good and regression generally is obtained with steroid therapy or with plasma exchange and vidarabine when polyarteritis is related to hepatitis B virus. In some cases ureteral stenosis may require an operation in association with steroids and/or immunosuppressive treatments.
