Abstract:
Although cytomegalovirus (CMV) infection is common in renal transplant recipients, urinary tract involvement has been rare. Only six cases of symptomatic ureteritis have been reported in renal transplant recipients and all within the last five years. We describe an additional four cases of CMV ureteritis. The presentation of CMV ureteritis is obstructive nephropathy often in the absence of systemic illness. Presentation may also mimic allograft rejection with minimal obstructive symptoms. We hypothesize that CMV ureteritis is an emerging complication of CMV disease, possibly due to changes in transplant practice.
Insights
Cytomegalovirus (CMV) ureteritis is an emerging complication in kidney transplant patients, presenting as obstructive nephropathy or mimicking allograft rejection. This rare urinary tract involvement highlights evolving challenges in post-transplant care.
Area of Science:
- Nephrology
- Transplant Surgery
- Infectious Diseases
Background:
- Cytomegalovirus (CMV) infection is a frequent complication following renal transplantation.
- Urinary tract involvement by CMV, particularly ureteritis, has been historically rare in this patient population.
Observation:
- This study reports four new cases of symptomatic CMV ureteritis in renal transplant recipients.
- These cases add to the limited number previously documented, with all reported cases occurring within the last five years.
Findings:
- CMV ureteritis often presents as obstructive nephropathy, frequently without systemic signs of CMV disease.
- The condition can also manifest with symptoms resembling allograft rejection, even with minimal urinary obstruction.
Implications:
- CMV ureteritis may be an emerging complication of CMV disease in renal transplant recipients.
- Changes in transplant practices might be contributing to the increased incidence of this rare complication.
