Contrast-enhanced computerized tomography (CT) scans of the transplanted kidney. (a-e) CT scan at admission showing the subcapsular hematoma (arrows). (a, b) Arterial phase. (c) Venous phase. (d) Coronal reconstruction. (e) Sagittal reconstruction. (f, g) CT scan at 4-month follow-up control showing the resolution of the subcapsular hematoma (late arterial phase). In (f, g), the arrows indicate the site of the previous hematoma.

Contrast-enhanced computerized tomography showed a subcapsular hematoma of 6.5 x 3 x 12 cm with regular urinary outflow, without signs of contrast leakage outside the vascular bed (Figures 1(a)-1(e)). The complete resolution of the SRH was demonstrated by abdominal ultrasound after 19 days and confirmed at a CT-scan performed 4 months later (Figures 1(f) and 1(g)).
Clinical and biochemical parameters during the hospital stay. (a) Systolic and diastolic arterial blood pressure. (b) Creatinine concentration and estimated glomerular filtration rate. (c) Blood urea nitrogen concentration.

Renal function, urinary output, and blood pressure remained stable and within the normal range during the whole hospital stay (Figure 2), and the SRH underwent progressive reduction.
Contrast-enhanced magnetic resonance imaging at day 9 showing the dimensional reduction of the subcapsular hematoma in the transplanted kidney and the absence of fluids in the perirenal spaces. (a) Axial T2-weighted. (b) Axial T1-weighted.

At day 9, a contrast-enhanced magnetic resonance reported the SRH dimensional reduction and the absence of fluids in the perirenal space (Figure 3).
