Introduction: Spontaneous intraperitoneal rupture of pyonephrosis is an extremely rare condition. It leads to generalized peritonitis that mimics an acute abdomen caused by intraperitoneal visceral pathology. In most cases, the underlying cause is obstructive urinary tract stones, followed by pelviureteric junction obstruction, tumors, or connective tissue diseases. We report the first case of spontaneous intraperitoneal fistulization of pyonephrosis from a duplex kidney. Conclusions: This case highlights the importance of considering renal etiology in the differential diagnosis of generalized peritonitis and underscores the rarity of such occurrences.
