Abstract
This work aims at formulation of a cohort study on the evaluation of various
Cases of upper urinary tract dilatations from the antenatal period through postnatal management, stressing on the following headings:
1- selection of the appropriate diagnostic schedule, proper therapeutic intervention and the follow up protocol.
2- delineation of indications and techniques of antenatal interventional procedures in the light of current standards, and assessing their results as well as complications.
3- potential diagnostic work up to set the final postnatal diagnosis .
4- setting the plan of postnatal management according to each diagnostic category.
5- postnatal evaluation of both conservative and surgical managements.
6- follow up to conclude the general outcome and prognosis in the cases of antenatally diagnosed hydronephrosis.
The first natal ultrasound ideally should be delayed for 72 hours after birth to confirm hydronephrosis.
لbilateral hydronephrosis or hydronephrosis of a single kidney warrants more urgent postnatal investigations and management.
Even if the initial postnatal ultrasound is normal, a repeat examination should be performed between l and 4weeks.
Voiding cystourethrogram is indicated in all children with antenatal hydronephrosis even those in whom hydronephrosis was found to be resolved postnatal.
Prophylactic antibiotics may prevent urinary tract infection in children being investigated for antenatal hydronephrosis especially when performing in evasive tests such as vcug and urethrocystoscopy.
13- Hypostasis experience and outcome of different operative procedures
