Retroperitoneal Fibrosis

Idiopathic Retroperitoneal Fibrosis: A Long-Term Follow-Up Study

“…Left untreated, the inflammation tends to progress slowly, blocking any hollow organ, especially the ureters and the major blood vessels [Hem and Mathisen, 1984], Typically, the patients in this study were mostly mid dle-aged men. In addition, oliguria or anuria were the presenting symptoms in 4 patients, a percentage similar to other reports [Kinder, 1979], Back pain, renal colic and low-grade fever were the most common clinical signs.…”

“…Although a medial deviation of the ureter can be seen in normal patients, the paradox of dilatation of the renal pelvis and ureter and the lack of any obstruction to the retrograde passage of an ureteric catheter should be considered as diagnostic for the dis ease [Tiptaft et al, 1982], In contrast to others [Hem and Mathisen, 1984], computerized tomography was of diag nostic value and capable of detecting the abnormal tissue in all patients examined.…”

“…As the name implies, RPF presents with a grayish-white fibrous plaque, more dense in the midline, usually at the bifur cation of the aorta [Hem and Mathisen, 1984], The idio pathic form of the disesae appears usually in men of late middle age with back pain, renal impairment and not rarely with anuria [Deane et al, 1983], An autoimmune mechanism seems to be of prime importance in the pathogenesis of the disease [Wagenknecht and Hardy, 1981], although genetic or familial factors have recently been incriminated [Duffy et al, 1984], The selection of a therapeutic strategy remains controversial. The proce dures recommended by the different centers vary from corticosteroids alone [Morandi and Grob, 1971 ;Ross and Goldsmith, 1971;Ochsner et al, 1975] to ureterolysis and/or to autotransplantation [Palleschi and McAninch, Patients and Methods During the last 12 years, 11 cases (8 male) were diagnosed as having idiopathic RPF (IRPF).…”

Idiopathic Retroperitoneal Fibrosis – An Update

“…There was a urinary fistula in 7 and 1 death from obstructive uropathy. Wagenknecht and Auvert [51 ] [80], but in this series steroids were used in a number of their patients.…”

Application de la résonance magnétique nucléaire aux écoulements diphasiques

“…Il est maintenant possible d'obtenir le profil des vitesses dans une section de canalisation [15]. Plusieurs revues sur l'utilisation de la RMN dans la caractérisation des écoulements ont déjà été publiées [16][17][18][19][20]. Cela dit, très peu de travaux ont été publiés sur l'application de la RMN à la caracté-risation des écoulements multiphasiques.…”
