The rate of antenatal resolution was significantly higher in the A1 group (64%) compared to the A2\u20133 group (3%) (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.05). The female gender was protective and had higher spontaneous prenatal resolution among UTD A1 fetuses. However, post\u2010natal persistence at 1\u2009year (49% vs. 0.2%) and the need for surgery (32% vs. 1%) were higher in the A2\u20133 group. Higher maximum anteroposterior renal pelvic diameter (APRPD) and ureteric abnormalities in the last scan were independent predictors for surgery.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Ours is one of the largest prospective studies on UTD classification.
