Ureteral obstruction caused by vasculitis.

Area of Science:

• Nephrology
• Urology
• Rheumatology

Background:

• Ureteral obstruction is a serious condition that can lead to kidney damage.
• Vasculitis, a group of autoimmune diseases, can affect various organs, including the urinary tract.

Observation:

• Two cases of ureteral obstruction secondary to vasculitis are presented.
• Case 1 involved polyarteritis nodosa, and Case 2 involved systemic lupus erythematosus.

Findings:

• Case 1, with undiagnosed vasculitis preoperatively, underwent ureteral resection and reimplantation.
• Case 2, managed with chlorambucil and corticosteroids, experienced resolution of ureteral obstruction.

Implications:

• This highlights the diverse clinical presentations of vasculitis affecting the urinary system.
• It suggests that medical management can be effective for vasculitis-induced ureteral obstruction, potentially avoiding surgery.
