ABSTRACT

Objective To summarize the diagnosis and treatment strategy of the retroperitoneal fibrosis(RPF)associated with hydronephrosis.Methods The clinical data of 26 RPF cases treated from Jan.2005 to Mar.2012 were analyzed retrospectively.Early symptoms mainly included lumbar,flank,abdominal pain,nausea and vomit.Retroperitoneal mass was found in 12(46.2％)cases by ultrasonography,while in 23(88.5％)cases by CT.Results Ureterolysis with intra-peritoneal transposition was underwent in 10 cases who were followed up for 6-25 months,and no relapse was found.Ureterocystostomy was underwent in 1 cases for difficulty in ureterolysis who was followed up for 45 months,and no relapse was found.D-J stent inter-ureter drainage was performed in 15 cases,all of whom had replaced the D-J stent discontinuously except that 2 cases had ceased replacement successfully,and all of the obstruction were relieved during the follow-up period for 16-84 months post-operatively.Conclusions Retroperitoneal mass can be found by CT of abdomen effectively.The therapeutics should depend on the pathological condition of the retroperitoneal mass.Obstruction can be relieved effectively by both ureterolysis with intraperitoneal transposition and D-J stent inter-ureter drainage and replacement.The complication occurred in the replacement of D-J can be relieved or eliminated by all kinds of measures.The unimpaired kidney drainage should be paid attention in the follow-up.
