Laparoscopic ureterolysis for retroperitoneal fibrosis :one case report

Abstract

Objective To investigate the feasibility of laparoscopic surgery for hydronephrosis caused by retroper-itoneal fibrosis.Methods Reported the diagnosis and treatment procedure and result of 1 case of hydronephrosis caused by retroperitoneal fibrosis on left side,who underwent laparoscopie surgery.Investigated the feasibility of hydronephrosis caused by retroperitoneal fibrosis with literature review.A 55-year-old female patient had interrupt-able left lower extremity swollen with nausea and vomiting for five months.The blood test showed progressive eleva-ting of creatinine and urea nitrogen.The highest creatinine value was 503 μmol/L.The computerized tomography showed renal atrophy on right side and there was a stenosis on crossing place between inferior segment on left ureter and iliac blood vessels,also there is a soft tissue image in front of aorta and around iliac blood vessels,the superior ureter was dilated.We set double J tube into left ureter before surgery with semi-reclining position toward right side,set trocar cannula through 1 era,4 em below the umbilicus as well as the same two points on lateral external oblique muscle of abdomen,set laparoscope from 1 cm below the umbilicus.We found the abdominal membrane pale and touch as tabular.There was serious eonglutination between middle segment ureter and around iliac blood vessels after we cut open retroperitoneal membrane.We carefully dissected the ureter for 9 cm and soluted the eonglutination a-round the ureter,then set the ureter into abdominal cavity and closed retroperitoneal membrane.Results The pa-tient recover well after surgery and sutured out after 5 days,pulled out the double J tube after I month.The patient had low back pain ,fever and oliguria after the double J tube was pulled out and recovered with spasmolysis,analge-sia and antibiosis treatment after 2 days.The voiding volume and renal function became normal.The B-type ultra-sound test showed hydronephrosis on left side was lessened.The ultrasound test after 3 months result showed hydro-nephrosis was significantly lessened than before surgery and renal function was normal.Conclusions The laparo-scopic ureterolysis surgery for retroperitoneal fibrosis is minimally invasive,less suffering and quick recovery.Be-cause of few case report and short follow-up time is more eases and long-term follow-up are needed to elucidate the therapeutic efficacy of this treatment.
