In 2016, the American Urological Association/Endourological Society issued general management guidelines for the various presentations of stones that can be managed conservatively. The guidelines state that observation with or without medical expulsive therapy (MET) should be offered to patients with uncomplicated distal ureteral stones that are 10 mm or less in diameter. The guidelines also state that active surveillance can be offered for asymptomatic, non-obstructing caliceal stones. [44]

In the case of pediatric patients with uncomplicated ureteral stones ≤10 mm or asymptomatic non-obstructing renal stones, active surveillance with periodic ultrasonography can be offered. Pregnant patients with ureteral/renal stones with well-controlled symptoms can also be observed. [44]
