[Spontaneous renal rupture]
Objective:
To study clinical regularity of spontaneous renal rupture.
Methods:
16 cases of this disease were reviewed. Renal carcinoma was found in 4, angiomyolipoma in 2, undetermined etiology in 3, and invasive colic cancer, kidney cyst, nephrolithiasis, SLE with nephritis, polycythemia vera, renal tuberculosis, portal hypertension in 1 each.
Results:
CT demonstrated a sensitivity of 87.5% in identifying the underlying kidney mass, which was higher than that (25%) of B-type ultrasound and (0) KUB + IVU. Radical nephrectomy was carried out in 6 cases, renal-reserved operation in 5, and conservative treatment in 5.
Conclusions:
60% of spontaneous renal rupture are due to kidney neoplasia. CT scanning is the most valuable diagnostic procedure. If the primary cause has not been clarified, close follow-up with periodic CT scanning might be mandatory.
