Conclusion
This study demonstrates that there is a relationship between acute flank
pain and hydronephrosis and that the severity of pain increases as the
degree of hydronephrosis increases. Especially in nulliparas, this
relationship is stronger. Urinary US should be performed in all pregnant
women presenting with acute flank pain. Ureteral JJ stent is a safe and
effective treatment method in pregnant women who do not respond to
conservative treatment.
