“Mirror” ureteric colic caused by proximal ureteric calculus in massively hydronephrotic kidney

Patients with ureteric calculi usually present with ipsilateral “loin to groin” pain. Rarely ureteric colic may present with contralateral pain, which is referred to as “mirror pain”. We report the case notes of a rare presentation of contralateral ureteric colic or “mirror pain” secondary to a ureteric calculus. A comprehensive literature review was also conducted. “Mirror pain” or contralateral ureteric colic is rare. Urologists should be aware of this unusual clinical presentation and appreciate that upper urinary tract calculi can cause pain on the contralateral side.
