Is there a difference in the number of interstitial cells, neurons, presence of fibrosis and inflammation in ureteropelvic junction tissues of patients with ureteropelvic junction obstruction with and without crossing vessels?

Number of ICs, neurons, presence of fibrosis and inflammation seem to be similar in the intact UPJ and UPJ with obstruction with and without crossing vessel. Cellular function rather than the number ICs might play a role that warrants further research.
