Post traumatic rupture in patients with uretero pelvic Junction obstruction: a Case Report

ABSTRACT

Authors report a case of post traumatic pelvic rupture occurring in an unknown ureteropelvic junction [UPJ] obstruction. Ultrasonography showed pyelectasia and fluid effusion in the anterior perirenal space. CT scan confirmed the diagnosis of UPJ obstruction and showed the rupture of the anterior pelvic wall communicating with a perirenal urinoma. The patient underwent a retrograde stenting for decompression and surgical drainage of the urinoma. Pyeloplasty was performed 4 months after injury. A follow up intravenous pyelogram showed good flow through the repair and the patient remaines asymptomatic 2 years after treatment Post traumatic rupture of UPJ obstruction is a rare event with few reported cases in literature Diagnosis is suggested on imaging studies. CT scan shows the rupture site in the ureteropelvic tract and guides percutaneous drainage
