Urolithiasis – a challenge during pregnancy

Urolithiasis during pregnancy is a rare condition despite the prolithogenic state determined by the physiological changes in the urinary system. The incidence is similar among pregnant women and the general female population, pregnancy not being a risk factor for the appearance of kidney stones. Urolithiasis is a challenge for the obstetrician because diagnosis and treatment require a particular approach in order not to harm the fetus. Ultrasonography is the first choice for diagnosing kidney stones even though it has a reduced sensibility. The first line of treatment in renal colic is expectant management. If this is ineffective, then urological interventions are being taken into consideration. Left untreated, urolithiasis exposes the pregnancy and the baby to higher risks of complications.
