IMPACT OF GENDER IN NEPHRON SPARING SURGERY: COMPARISON OF PERIOPERATIVE OUTCOMES FROM THE DEFINITIVE RESULTS OF RECORD PROJECT

Aim of the study The aim of this study is to analyse gender in nephron sparing surgery (NSS) comparing males vs females in terms of epidemiological and clinical features in a multicentre Italian dataset (RECORd Project). Materials and methods Overall, 1055 patients treated with nephron sparing surgery (NSS) between January 2009 and December 2012 were evaluated. A comparison of gender on pre-, intra- and post-operative variables was performed. Results Overall, 630 males and 346 females were analysed. No significant difference was found between males and females in age (analysed as continuous and nominal ) Discussion It seems that NSS in males presents a higher difficulty (higher EBL, intraoperative time and intraoperative complication). A possible explication can be higher BMI and surgical indication, but this result should be further confirmed by a matched pair comparison. Females present higher rate of benign tumours, as described in literature. Males present a slightly higher clear cell RCC rate with higher Fuhrman grade. Conclusions To our knowledge this is the main Italian analysis regarding epidemiologic and clinical features in NSS related to gender.
