We describe a patient who underwent an emergency aneurysmectomy for a ruptured renal aneurysm following cesarean section, in whom renal function was preserved. A 31-year-old woman presented with gestational diabetes mellitus at a local hospital. She underwent an emergency cesarean section because of placental abruption. Left low back pain and upper back pain suddenly developed 17 hours after childbirth. A computed tomographic scan revealed a ruptured aneurysm of the left renal artery, and we performed coil packing of the aneurysm. However, complete packing was impossible because of the large size of the aneurysm. We therefore decided to operate. The ruptured aneurysm was removed through a retroperitoneal approach, and the renal artery was directly reconstructed by end-to-end anastomosis. Renal aneurysms are considered to be at high risk of rupture during pregnancy. However, to the best of our knowledge, no study has reported rupture of a renal aneurysm after cesarean section. Surgical treatment yielded a good outcome, and renal function was preserved.
