Pseudo-renal failure with hyponatremia and proteinuria after gynecologic surgery: a case report with literature comparison

This case highlights the importance of recognizing pseudo-renal failure as a differential diagnosis of unexplained azotemia, particularly in patients with recent pelvic surgery. The coexistence of elevated serum creatinine with relatively preserved cystatin C, ascites, hyponatremia, and nephrotic-range proteinuria should raise suspicion for urinary tract injury. Measurement of ascitic fluid creatinine and CT cystography are key diagnostic tools for genitourinary trauma that can prevent unnecessary invasive procedures and guide timely therapeutic interventions. Ultimately, awareness of this entity enables prompt diagnosis and favorable clinical outcomes for patients.
