Purpose: We attempted to clarify the details of incidental splenectomy
complicating left nephrectomy. Materials and Methods: We reviewed the
literature and operations involving splenectomy performed during left
nephrectomy between 1984 and 1994 at our university. Factors reviewed
included patient characteristics, renal pathology. mechanisms of inju
ry, blood transfusions and postoperative complications. Results: Of th
e 418 left nephrectomies 18 (4.3%) resulted in splenectomy via a trans
peritoneal approach. Patients with a large or upper pole renal lesion,
malignancy or advanced age are increasingly likely to undergo unantic
ipated splenectomy. Conclusions: Our results, combined with recommenda
tions from the Centers for Disease Control and Prevention, suggest tha
t all patients older than 65 years undergoing left transperitoneal nep
hrectomy or those at increased risk for splenic injury should receive
preoperative pneumococcal vaccination.
