Management of urological tumours in pregnancy.

Urological tumours are rare in pregnancy and may be mistaken for other, more common conditions such as urinary infection, pyelitis, threatened abortion or pre-eclampsia. With modern imaging techniques, especially ultrasonography and NMR, the diagnosis can be accurately established. In collaboration with obstetric and medical colleagues, the urologist can deal with these tumours safely and effectively, provided that the timing and extent of treatment are carefully tailored to the stage of the pregnancy.
