Pre- and postnatal therapy of lower urinary tract obstruction - an experience of 18 years

Kluwe, Wolfram; Muller Brochut, A.-C.; Raio, Luigi; Mc Dougall Müller, FJ; Thomann, Daniel (2009). Pre- and postnatal therapy of lower urinary tract obstruction - an experience of 18 years. In: 9th World Congress of Perinatal Medicine. Berlin, Germany. 26.10.2009.

With prenatal detection of hydronephrosis and technological advances in surgical equipment, the management of lower urinary tract obstruction has evolved to include prenatal surgical intervention. Surgical intervention, was based upon the rationale that restoring amniotic fluid to normal levels by shunting fetal urine from the obstructed urinary system to the amniotic space would prevent lung hypoplasia and, thus, improve neonatal survival. Inaddition, relief of the obstruction would also reduce back pressure and reduce injury to the developing nephron, thus improving long-term renal function postnatally. However, this remains investigational, and the vast majority of affected infants are treated soon after birth. We have experience since 1991 with prenatal treatment of megacystis. In 23 cases of 50 detected megacystis with oligohydramnion in male and without other abnormalities a prenatal intervention by bladderpunction and in 12 cases additional vesicoamniotic shunt placement was performed. The prognosis of megacystis with oligohydramnion is stated with a survival rate of 10-30%. In our group 54% (13 children) survived. Also we want present 56 cases of urethral valves with a postnatal transurethral intervention. With a follow up time from 8.6 (3 to 15) years we attend 34 children (60%) with normal renal function, 21% (12) with mild or moderate renal insufficiency and there was a kidney transplantation in 6 cases necessary. With our multidisciplinary presentation we want to discuss the indication, interdisciplinary aspects,risks and the follow up of pre- and postnatal intervention in such cases.
