[Spontaneous renal subcapsular or perinephric haematoma].

OBJECTIVE

To improve the diagnosis and treatment of spontaneous renal subcapsular and perinephric haematoma.

METHODS

Seventeen cases of spontaneous renal subcapsular or perinephric haematoma were analyzed retrospectively. For imaging diagnosis, we used ultrasonography, computerized tomography (CT) and angiography. Thirteen cases were subjected to nephrectomy and one case was to renal biopsy, whereas the remaining 3 cases were treated conservatively.

RESULTS

After follow up for 6-108 months, 3 patients died and 14 patients survived.

CONCLUSIONS

For diagnosis, imaging examinations are very valuable. For treatment, most of patients with perinephric haematoma should be operated on.
