mpMRI induces robotic surgeons to change the surgical plan in almost half of individuals, thus tailoring the NS approach, without compromising the oncologic outcomes. Compared to patients treated without mpMRI, the use of preoperative mpMRI can significantly reduce the overall PSMs.

The rates of muscle protein breakdown, as estimated by the urinary excretion of 3-methylhistidine, were assessed in 30 cirrhotics and 15 controls on a strictly controlled diet. 3-Methylhistidine excretion was increased in cirrhotics irrespective of the etiology of the disease, and correlated with basal glucagon levels and with the insulin/glucagon ratio. In nine cirrhotics and nine age- and sex-matched controls, similar correlations were found between 3-methylhistidine and the areas under 24-hr glucagon or insulin/glucagon curves. A larger amount of 3-methylhistidine was excreted during the nighttime than during the daytime, when glucagon secretion was suppressed and the insulin/glucagon ratio was increased. It is concluded that muscle protein catabolism is increased in cirrhotics, possibly as a result of hyperglucagonemia or the reduced insulin/glucagon ratio. These data agree with the clinical observation of a progressive reduction in lean body mass which becomes evident in an advanced stage of the disease.
