Infectious disorder of kidney

Last edited: 4/22/2026

Overview

Fraleys syndrome involves vascular compression affecting the upper pole infundibulum of the kidney, often leading to dilatation of the upper pole calyx, typically on the right side, and can cause recurrent lumbar pain 1.

Diagnosis

  • Clinical Presentation: Recurrent lumbar pain, often necessitating emergency care 1.
  • Diagnostic Imaging: Renal arteriography is crucial for definitive diagnosis 1.
  • Imaging Findings: Vascular compression on the superior infundibulum with secondary calyx dilatation 1.
  • Management

  • Surgical Interventions:
  • - Upper-Pole Nephrectomy: Effective in resolving symptoms when complications arise or persist 1. - Calycopyeloneostomy: Preferred initial surgical approach to preserve renal parenchyma in uncomplicated cases 2. - Artery Transposition: Often performed alongside calycopyeloneostomy to manage vascular compression 2.

    Special Populations

  • Comorbidities: No specific management differences noted for comorbid conditions in the provided abstracts 12.
  • Key Recommendations

  • Perform renal arteriography for definitive diagnosis of Fraleys syndrome (Evidence: Moderate 1).
  • Consider calycopyeloneostomy as the primary surgical treatment to preserve renal function (Evidence: Weak 2).
  • Resort to upper-pole nephrectomy if complications occur or initial surgical interventions fail (Evidence: Expert opinion 12).
