Rupture of a Subcapsular Hematoma After Kidney Transplant: Case Report.
Subcapsular hematoma after kidney transplant may result in kidney ischemia and graft loss. In this report, we present a patient who had a subcapsular hematoma that had no intraoperative enlargement but ruptured after surgery. A man who had chronic kidney disease secondary to hypertension had a preemptive living-donor kidney transplant from his wife. After declamping, appropriate renal perfusion and urinary output were observed. At perfusion, a subcapsular hematoma (diameter, 3 cm) was observed at the upper pole of the kidney. The hematoma did not enlarge during the surgery. Capsulotomy was not performed due to possible risks, and transplant surgery was completed with the plan for close postoperative ultrasonography and hemodynamic follow-up. Decreased urinary output was observed early after surgery. Renal Doppler ultrasonography showed decreased diastolic flow and a hematoma (width, 9 mm) that completely surrounded the transplanted kidney. The patient had emergency reoperation due to active hemorrhage from his surgical drain at 40 hours after surgery. Rupture of the capsule and hemorrhage from the surface of the kidney were observed. Extended capsulotomy and hemostasis of the kidney were performed. After surgery, urinary flow increased and renal Doppler ultrasonography findings improved. In summary, intervention for a subcapsular hematoma after kidney transplant is controversial. Capsulotomy should be considered for treatment of increased pressure to the graft, risk of permanent damage, and risk of graft loss.
