RARP was performed by two experienced surgeons using similar techniques.

In comparison, seven (11%) patients in Cohort 2 (with Arista AH) suffered from post\u2010op UTI, and only one (14%) was associated with leak.<\/jats:p><jats:p>There was an overall reduction in leaks on post\u2010op cystograms from 44 (29%) in Cohort 1 to only nine (15%) in Cohort 2 (<jats:italic>p<\/jats:italic>\u00a0=\u20090.036).<\/jats:p><jats:p>One hundred per cent of the leaks in Cohort 2 were small, compared to nine (20%) in Cohort 1 (<jats:italic>p<\/jats:italic>\u00a0=\u20090.0002).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>A selective approach can be implemented with regard to post\u2010op cystograms.<\/jats:p><jats:p>We propose that when using Arista AH cystograms should be carried out in patients in need of bladder neck reconstruction.
