Abstract
The incidence of an antenatally detected genitourinary abnormality is 0.5% of all pregnancies assessed, and rarely is antenatal intervention indicated. The most common urological abnormality diagnosed antenatally is hydronephrosis and carries an excellent prognosis. In majority (> 50%) the antenatally detected dilatation is transient and resolves spontaneously. Currently any intrauterine manipulation or surgery should be reserved for a fetus that has bilateral involvement that is progressive, destructive, and associated with oligohydramnios. If bilateral renal agenesis, bilateral multicystic kidneys, or bilateral infantile polycystic kidneys are demonstrated early in gestation, the obstetrician and parents may choose to terminate the pregnancy because these conditions are not compatible with extrauterine life. Malformations like megaureter, ectopic kidney, ureteric duplication, unilateral renal agenesis/multicystic kidney and bladder exstrophy have a good prognosis. This review aims to outline the current management strategies in patients diagnosed with urogenital malformations in the antenatal and neonatal period.
