Background and Purpose: Because of the limited working space available during retroperitoneal laparoscopic radical nephrectomy (LRN), the body habitus of the patient is likely to affect the risk of operative difficulties. This study sought to determine whether anthropometric measurements based on CT and abdominal radiography could be used to predict operative difficulties during retroperitoneal LRN.
Patients and Methods: Between August 2004 and January 2012, 96 consecutive patients with preoperative CT and abdominal radiography examinations underwent retroperitoneal LRN for a T-1 or T-2 stage renal tumor at our institution. The association between anthropometric measurements and demographics of patients and operative duration, estimated blood loss (EBL), and perioperative complications were retrospectively analyzed. Multivariate analysis was performed, and P < 0.05 was considered significant.
Results: Anterior perirenal fat distance (P = 0.016) and distance from the 12th rib to the iliac crest (P = 0.038) were independently associated with operative duration. Only anterior perirenal fat distance (P = 0.001) was independently associated with EBL. No intraoperative complications and reoperations occurred. The occurrence or severity of postoperative complications was not significantly associated with anthropometric measurements. Body mass index >= 25.0 kg/m(2) was not significantly associated with operative difficulties.
Conclusion: The anterior perirenal fat distance and the distance from the 12th rib to the iliac crest can be used to predict operative difficulties during retroperitoneal LRN.
