Diagnosis:  Mild-moderate right hydronephrosis

  • Urinary tract obstruction, in this case secondary to a distal ureteral stone, can lead to infection, sepsis, and permanent renal injury
  • Patients with infection in conjunction with obstructing renal stone require urologic consultation and admission for IV antibiotics covering gram negative organisms
  • Urologic interventions for nephrolithiasis include shock wave lithotripsy, ureteral stenting and less commonly laparoscopic stone removal
