Ureteropelvic junction obstruction caused by metastatic cholangiocarcinoma

Abstract: We describe the rare case of a 61-year-old female with right ureteropelvic junction (UPJ) obstruction caused by metastatic cholangiocarcinoma. Her past medical history was notable for cholangiocarcinoma treated with neoadjuvant chemoradiation and two orthotopic liver transplants six years earlier. Urology was consulted when she presented with fl ank pain and urinary tract infection. Diagnostic workup demonstrated right UPJ obstruction. She was managed acutely with percutaneous nephrostomy. She subsequently und… Show more

“…Cholangiocarcinoma (CCA), the second most common type of primary liver cancer, is a type of cancer that pathologically arises from the dysregulation of bile duct epithelial cells [1]. CCA-related morbidity has been significantly increasing, as confirmed by a large surveillance, epidemiology and end results database review reporting a 128% net increase in the last 40 years [2].…”

“…Pelviureteric junction (PUJ) obstruction is a common urological disorder with an incidence of 1 in 1000 to 1500 live births; however, the incidence is not well-defined in adults. [1][2][3] Congenital causes are common, and PUJ obstruction (PUJO) accounts for 5% of antenatal hydronephrosis cases. [2] However, patients may present at any stage of life, and the most common primary symptom is flank pain, although PUJO may also be detected incidentally.…”

“…Cholangiocarcinoma (CCA) is the uncontrollable transformation of biliary duct cells derived from intrahepatic and extrahepatic bile ducts (Blechacz 2017 ; Pickersgill et al 2019 ). In recent years, the frequency of cholangiocarcinoma has increased gradually (Siegel et al 2018 ).…”
