Recurrent urinary tract infection was the most common clinical presentation (55%, <jats:italic>n<\/jats:italic>\u2009=\u20096). Other presentations included flank pain (36%, <jats:italic>n<\/jats:italic>\u2009=\u20094), collection\/ abscess (45%, <jats:italic>n<\/jats:italic>\u2009=\u20095), and nephro-cutaneous fistulae (9%, <jats:italic>n<\/jats:italic>\u2009=\u20091). The majority of patients had bacteriuria (91%, <jats:italic>n<\/jats:italic>\u2009=\u200910), and <jats:italic>Escherichia coli<\/jats:italic> was the most common bacteria isolated (55%, <jats:italic>n<\/jats:italic>\u2009=\u20096). Antibiotic resistance was seen in 60% of positive urine samples (<jats:italic>n<\/jats:italic>\u2009=\u20096). An open nephrectomy was performed in all but one case (91%, <jats:italic>n<\/jats:italic>\u2009=\u200910). A postoperative complication occurred in 73% (<jats:italic>n<\/jats:italic>\u2009=\u20098), with 50% (<jats:italic>n<\/jats:italic>\u2009=\u20094) of complications Clavien Dindo grade 3 or higher, including one patient mortality.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusions<\/jats:title>\n                <jats:p>XGP is a difficult and complex condition to treat. All patients in this series presented with infection or associated sequelae thereof. Complex XGP cases therefore often require open nephrectomy and have high rates of postoperative complications.
