It is defined as an extensive dilatation of the pyelocaliceal cavities occupying a large part of the abdominal cavity. Giant hydronephrosis is usually due to pelvi-ureteric junction obstruction and is usually diagnosed in children and infants. Ureterocele, which is a cystic dilatation of the terminal ureter, often drains the upper part of the kidney in patients with a duplex system. Massive hydronephrosis in a patient with duplex system and obstructive ureterocele was described by Aeron et al. in 2017. A thorough search of the major medical databases disclosed that no other cases have been reported since. We describe a second case of unilateral complete duplex system with ureterocele and massive hydronephrosis of the upper moiety in an adult man with intermittent abdominal pain associated with constipation and a decrease in appetite. The renal function of the left kidney was 8% of total function by radionuclide renal scan. The patient subsequently underwent left laparoscopic nephrectomy.<\/jats:p>","DOI":"10.4081\/aiua.2020.4.318","type":"journal-article","created":{"date-parts":[[2020,12,18]],"date-time":"2020-12-18T12:24:07Z","timestamp":1608294247000},"source":"Crossref","is-referenced-by-count":3,"title":["Giant hydronephrosis secondary to ureterocele with duplex system in adults: Report of a case"],"prefix":"10.4081","volume":"92","author":[{"given":"Andrea","family":"Solinas","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Luca","family":"Cau","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Massimiliano","family":"Fanari","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ignazio","family":"Flaviani","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Francesco","family":"Manca","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maurizio","family":"Melis","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"2549","published-online":{"date-parts":[[2020,12,18]]},"reference":[{"key":"28054","doi-asserted-by":"crossref","unstructured":"Aeron R, Sokhal AK, Kumar M, Sankhwar S.
