Prenatal ultrasound detection of fetal ureterocele with bilateral hydroureteronephrosis, obstruction of the bladder outlet and progressive amniotic fluid reduction have been associated with a significant risk of end-stage chronic renal disease after birth. Fetal cystoscopic laser incision of the ureterocele, using standard 3.5-mm fetoscopic access to the amniotic cavity and the fetal bladder with the aim of relieving the bladder outflow obstruction to preserve renal function, has been reported previously in a case with a favorable outcome. We report on two additional cases of fetal ureterocele treated by cystoscopic laser decompression. In the first case, a standard 3.3-mm uterine entry was used. In the second case, a new approach was adopted using an ‘all-seeing needle’ 1.6-mm endoscope.
