Summary

The nutcracker phenomenon, a left renal vein compression, can coexist with immunoglobulin A nephropathy. This complication presents with specific urinary and blood markers, necessitating renal biopsy for diagnosis.

Area of Science:

  • Nephrology
  • Vascular Medicine
  • Urology

Background:

  • The nutcracker phenomenon involves left renal vein compression between the superior mesenteric artery and aorta.
  • Key features include non-glomerular hematuria and left renal vein stenosis with distal dilation.

Purpose of the Study:

  • To compare patients with nutcracker phenomenon alone versus those with coexisting immunoglobulin A nephropathy.
  • To identify distinguishing clinical and laboratory features of complicated nutcracker syndrome.

Main Methods:

  • Retrospective comparison of two patient groups: nutcracker phenomenon with IgA nephropathy (n=2) and nutcracker phenomenon alone (n=10).
  • Analysis of clinical presentation, urinalysis, serum IgA levels, and renal biopsy findings.

Main Results:

  • Patients with coexisting IgA nephropathy exhibited aggravated hematuria post-respiratory infections.
  • Glomerular origin of hematuria, elevated serum IgA, persistent proteinuria, and granular casts were noted in the complicated group.
  • These specific findings aided in suspecting IgA nephropathy in nutcracker phenomenon patients.

Conclusions:

  • The combination of nutcracker phenomenon and IgA nephropathy presents with distinct clinical and laboratory features.
  • Suspicion of coexisting IgA nephropathy is raised by specific hematuria characteristics and proteinuria.
  • Renal biopsy is essential for definitive diagnosis in suspected cases.
