Spontaneous Intraperitoneal Rupture of Giant Hydronephrosis Presenting as Acute Abdomen

Hydroureteronephrosis is caused by upper or lower urinary tract obstruction due to intrinsic or extrinsic causes. Functional lower urinary tract obstruction causing giant hydronephrosis in young adults is rare. Spontaneous intraperitoneal rupture of thinned-out renal cortex of giant hydronephrosis presenting as an acute abdomen in a young adult is exceedingly rare.
