Frequency of occurrence of vesico-ureteral reflux in kidney transplanted patients with the new technique of uretero-neo­ cystostomy (Barry-Taguchi)

There are several ways of performing vesico-ureteral anastomosis in kidney trans­plantation (Tx); they are broadly classified into two categories: extra-vesical and intra-vesical. Extra-vesical methods are preferred in kidney transplantation. In this study, we attempt to integ­rate two extra-vesical techniques of Barry and Taguchi and to evaluate the frequency of occu­rrence of vesico-ureteral reflux (VUR) with this technique. Also, an attempt is made to compare the results with other techniques reported in the literature. Fifty consecutive transplant recipients, who underwent uretero-neo-cystostomy (uretero-vesical anastomosis) by the new technique of Barry-Taguchi were evaluated for VUR by sonography and cystoureterography, six months after Tx. The mean age of the study subjects was 34.8 years; there were 33 males and 17 females. The mean time between Tx and evaluating for VUR was 6.6 months. Two cases of asymptomatic VUR (4%) were detected at the end of the study period. The occurrence of 4% asymptomatic VUR suggests that this technique is more acceptable compared to others. Because of the simple nature of the procedure as well as the short time required, this technique could be a suitable choice in kidney transplantation.
