Characteristics and Outcome of Babies with Antenatal Renal Pelvis Dilatation (RPD)

Background: Antenatal renal pelvis dilatation (RPD) is the most common congenital anomaly detected on antenatal ul-trasound. The present study was planned to determine characteristics and outcome of neonates with pel-vis dilatation. Patients Methods: A prospective, observational, non-interventional conducted in Fatima Memorial Hospital over a period 12 months from April 2021 March 2022. This included 130 kidneys 91 >28 weeks gestation antenatally diagnosed isolated Postnatal ultrasound performed at 24-72 hours life. Cases those resolved spontaneously were labelled as Physiological RPD (Transient RPD) , while all others Pathological (Persistent RPD).Descriptive statistics tests significance calculated for variables. Univariate analysis compare possible risk factors postnatal transient vs. persistent any grade. Correla-tion coefficients between pathological RPD. Results: Every 4th neonate had (p<0.05). Only 5% showed se-vere variety Statistically significant associated maternal anemia, oligohydramnios, diabetes mellitus, age < 37 weeks, birth weight <3 kg, antibiotics administration, admission in-tensive care unit, urinary tract infections, oliguria, high BUN creatinine, posterior urethral valve, vesicoureteral reflux, neurogenic bladder other malformations (P<0.05). Persistent strong positive direct correlation severity RPD, moderate seen serum PUV, PUJ. Hence will help us formulating management follow up plan our newborns Conclusion: About 71% undergo spontaneous resolution. Severe persisted neonatal life has dilata-tion.
