Medical Care

Optimal care in patients with retroperitoneal fibrosis (RPF) requires an integrated approach of surgical and nonsurgical therapies. The aims of management are to preserve renal function, to prevent other organ involvement, to exclude malignancy, and to relieve symptoms. The literature reports no consensus on the appropriate management of patients with retroperitoneal fibrosis because no controlled therapeutic trials have been performed. Furthermore, successful outcome has occasionally been reported with conservative therapy.[44, 45] In 2002, Pistolese et al reported partial or complete regression of retroperitoneal fibrosis associated with inflammatory aortic aneurysm after surgery.[5] The treatment of retroperitoneal fibrosis depends on the stage of the disease at diagnosis, as depicted in the image below.

Empirical therapy includes corticosteroids, tamoxifen, and azathioprine; experimental therapy includes azathioprine, cyclophosphamide, mycophenolate-mofetil, cyclosporin, medroxyprogesterone acetate, and progesterone. Glucocorticoids and azathioprine are most useful in patients with signs of inflammation (eg, raised ESR and WBC count and positive ANA results).

  • Corticosteroids
    • In 1958, Ross and Tinckler first reported the use of corticosteroids in the treatment of retroperitoneal fibrosis. The beneficial effect is thought to be due to anti-inflammatory action and the ability to inhibit fibrotic tissue maturation.
    • A pooled analysis of nonmalignant retroperitoneal fibrosis treated with steroids revealed a satisfactory outcome. In 2002, van Bommel analyzed 147 patients and noted good results in 122 patients (83%) and recurrence in 55 patients (16%). Most recurrences were noted within 12 months, and some responded to reintroduction of steroid.[46] Despite their proven success, using steroids as a first-line therapy in retroperitoneal fibrosis remains controversial because many clinicians believe that multiple deep biopsies are still essential to exclude malignancy.
    • A standard protocol is prednisolone at 40-60 mg/d tapered to 10 mg/d within 2-3 months and discontinued after 12-24 months. Timely dose reductions and cessation are important because of the adverse effects associated with long-term steroid use.
    • In 1994, Harreby et al used methylprednisolone pulse therapy (MPPT) at 1 g/d IV for 3 days along with azathioprine or penicillamine. This therapy was used in 11 cases of retroperitoneal fibrosis with ureteric obstruction following initial insertion of ureteral stents. The treatment was successful in 7 patients but only moderately effective in 4 patients. The combination of glucocorticoid and azathioprine is most useful in patients with signs of inflammation (raised ESR, positive ANA results, positive PET findings).[47]
    • Steroids can be used in combination with surgery. In one study, concomitant use of steroids with surgery reduced the rate of ureteric restenosis from 48% to 10%.[48] However, response may vary, and an unacceptably high dose of steroid may be required to control retroperitoneal fibrosis.
    • Complications of corticosteroid treatment include obesity, Cushingoid features, striae, retarded growth, and an increased susceptibility to infections, hypertension, osteoporosis, cataracts, peptic ulcer disease, and diabetes mellitus.
  • Tamoxifen
    • In 1991, Clarke et al were the first to use tamoxifen, a nonsteroidal antiestrogen, in the treatment of retroperitoneal fibrosis.[49]
    • Its mechanism of action is not entirely clear, and different hypotheses have been proposed. Tamoxifen increases the synthesis and secretion of transforming growth factor–beta (TGF-b), an inhibitory growth factor, by human fetal fibroblast in vitro. In retroperitoneal fibrosis, fibroblast and immune cells in the inflammatory mass may increase their secretion of TGF-b, which may then decrease the size of the fibrous plaque.[50] Other possible mechanisms of action include inhibition of protein kinase C, reduction of epidermal growth factor production, inhibition of calmodulin, and blockage of growth-promoting histaminelike receptor.[51, 52]
    • Clinicians have reported successful treatment with tamoxifen. Various authors have used tamoxifen with a variable protocol (10-40 mg for 6 mo to 3 y).
    • In a randomized, open-label, controlled trial, Vaglio et al compared the efficacy of prednisone with that of tamoxifen in maintaining remission among patients with idiopathic retroperitoneal fibrosis. A total of 40 patients (18-85 y) were enrolled in the study. Following induction therapy with 1 mg/kg daily of prednisone for 1 month, those patients who had achieved remission were randomly assigned to receive tapering prednisone (initial dose 0·5 mg/kg daily) for 8 months or tamoxifen (fixed dose 0·5 mg/kg daily) for 8 months. After 18 months, the authors found the cumulative relapse probability was estimated at 17% with prednisone and 50% with tamoxifen (difference -33% [-62 to -3, p=0·0372]). However, Cushingoid changes and grade 2 hypercholesterolemia were more common in the prednisone group than in the tamoxifen group (p=0·0116 and p=0·0408, respectively).[53]
    • Compared with steroids, the adverse effect profile of tamoxifen is low; thus, clinicians consider tamoxifen a reasonable treatment option. However, the adverse effects of tamoxifen, especially an increased risk of thromboembolism and ovarian cancer, should be carefully considered for each patient.
  • Mycophenolate mofetil
    • To block the proliferation of T cells and B cells, a combination of mycophenolate mofetil (MMF) and steroid appears to be a promising option.
    • Swartz et al (2008) reported their experience with high-dose corticosteroid and MMF in 21 patients. They used prednisone 60 mg or 120 mg qid for 3-6 months and tapered the dose upon clinical improvement. In addition, steroid-sparing therapy with MMF (1000 mg bid) was recommended, with discontinuation after 6-12 months of therapy.[54]
    • In a recent study, Adler et al (2008) observed radiologic regression following therapy with MMF 2 g/d and prednisolone 1 mg/kg in 9 patients. Therapy led to removal of the ureteral catheter in 5 of 7 patients. Complications of MMF therapy included recurrent urinary infections and upper gastrointestinal disturbance.[55]
  • Azathioprine: Azathioprine has been used when steroid therapy has failed and as a steroid-sparing drug. Cogan and Fastrez used a 6-week course of azathioprine (150 mg/d) in a patient whose condition recurred soon after prednisone treatment was discontinued. They observed a significant response with azathioprine.[56] McDougal and MacDonell reported successful outcome in combination with prednisolone in a 14-year-old girl.[16]
  • Experimental therapy: More recently, immunosuppressive agents such as azathioprine, cyclophosphamide, MMF, methotrexate, and cyclosporin have been used to treat retroperitoneal fibrosis. Future steroid-sparing options could include anti-inflammatory drugs such as tumor necrosis factor-alpha (TNF-a) inhibitors and anti-CD20 drugs.[16, 57, 56, 58, 59]
  • Medroxyprogesterone acetate: In vitro, medroxyprogesterone acetate inhibits fibroblastic proliferation. Use of progesterone and medroxyprogesterone acetate as an alternative treatment has been reported with successful outcome.[60, 61]

Surgical Care

  • Temporizing maneuvers in the form of percutaneous nephrostomy or ureteral stenting are recommended in the presence of obstructive uropathy.
  • Primary management of retroperitoneal fibrosis consists of open biopsy, ureterolysis, and lateral/intraperitoneal transposition or omental wrapping of the involved ureter, as depicted in the image below.Postureterolysis intravenous urogram demonstrates Postureterolysis intravenous urogram demonstrates lateral displacement of both ureters and a double J stent on the right side.
  • Open ureterolysis, although effective in 90% of patients, is associated with significant morbidity (60%) and mortality (9%) rates.[62, 63]
  • In the past 10 years, the use of laparoscopic surgery has expanded to include complex ablative and reconstructive procedures. Kavoussi first described laparoscopic ureterolysis for retroperitoneal fibrosis in 1992.[64] Since then, a few authors have reported successful laparoscopic ureterolysis with a more rapid recovery and a shorter hospital stay. Although the success rate is no better than that of open ureterolysis, the laparoscopic technique has the advantage of reducing mean hospital stay, use of analgesia, convalescence period, and morbidity.[64, 65, 66]
  • Styn et al compared open ureterolysis (12 patients) with laparoscopic ureterolysis (13 patients) and reported a significantly shorter hospital stay (open 5.9 d vs laparoscopic 2.1 d; p=.004).[67] The complication rates did not differ between the groups. The success rate was 87.5% after open ureterolysis and 93.8% after laparoscopic ureterolysis (p=1).
  • More recently, with the advancement of technology, cases of endourologic treatment of retroperitoneal fibrosis via percutaneous balloon dilatation or endoscopic incision, dilatation, and permanent wall stent have been reported, with varying results.[68]
  • Long-term ureteral stenting is a reasonable approach in high-risk and elderly patients. Ureteral stenting may be placed on a long-term basis (months to years) in order to bypass ureteral obstruction. Short-term stenting (weeks to months) may be used as an adjunct to open surgical procedures.
  • Other newer innovative surgical techniques have been described, such as ureterolysis and wrapping with Gore-Tex (GSM, WL Gore & Associates, Flagstaff, Ariz), excision of the ureter and reanastomosis, posterior preperitoneal flap, and renal autotransplantation.[69]
