    BACKROUND: To evaluate the factors including pelvic dimensions, which might influence operative difficulty and complications after open radical cystoprostatectomy and orthotopic neobladder reconstruction in men. METHODS: A total of 198 RC patients operated in our institution with preoperative magnetic resonance (MRI) were analyzed were included in the study. Pelvic dimensions, including interspinous distance (ISD), bony femoral - (BFW) and soft tissue width (SW), apical prostate depth (AD), upper conjugate (UC), lower conjugate (LC) were measured by preoperative MRI. BFW, ISD, and SW indexes were defined as BFW/AD, ISD/AD, and SW/AD, respectively. Complicatons were classified according to the Clavien-Dindo classification system. As indicators of surgical difficulty; transfusion rate (TR), estimated blood loss (EBL), operative time (OT) and hospital stay (HS) were assessed. SPSS version 17.0 was used for statistical analyses. RESULTS: A total of 239 complications developed in 143 of the 198 patients (72.2%). Correlation analysis revealed a significant indirect relationship between TR and SW/AD (P=0.023). For EBL, there were significant indirect correlations between the SW/AD, BFW/AD and ISD/AD indexes (P=0.026, P=0.05, P=0.009; respectively). Additionally, OT was directly correlated body mass index (BMI) (P=0.001); and indirectly correlated with UC, SW/AD, and BFW/AD (P=0.047, P=0.038, P=0.016, respectively). On multivariate logistic regression analyses higher American Society of Anesthesiologist (ASA) score was associated with major complications. Multivariate analyses revealed that pathological stage was a significant predictor of EBL. CONCLUSIONS: Patients with smaller pelvises might undergo more difficult surgeries. However, it seems that small sized pelvis does not impact on operative difficulty and complication rate in radical cystoprostatectomy and orthotopic neobladder.
