Hae Young Lee, In Soon Ahn, Jae Seung Yang, Beak Keun Lim, Jong Soo Kim
Clin Exp Pediatr. 1988;31(5):555-558.   Published online May 31, 1988
Comparison of urinary specific gravity by refractometer and osmolality in 238 neonates demonstrated as followings; 1) The regression line is represented by the equation: Y = 107+14.2 (X-1000) while Y = osmolality in mosm/kg X = Specific gravity by refractometer r=0.8545 2) Osmolality is the only accurate measure of urine concentration in newborn infants. If the specific gravity by refractometer is used to screen for urine concentration, an elevated level...

Hereditary elliptocytosis is characterized by elliptically shaped erythrocytes in peripheral blood and known to be transmitted as an autosomal dominant trait, but in some cases, inherited recessively. The clinical and hematologic expressions are variable range from healthy person with normal red cell morphology to severe hemolytic anemia. Recently, the authors experienced all three offsprings shown non-hemolytic hereditary el- liptocytosis, whose parents were healthy persons with...
A Case of Pyeloplasty in Neonatal Bilateral U-P-J Obstruction.

Ureteropelvic junction obstruction has been discussed extensively in literature, but most reports refer to adults or young children. Neonatal bilateral U-P-J obstruction has not been reported in Korea. Herein we present with bilateral ureteropelvic junction obstruction in neonate. Repair was achieved successfully using a non-intubated, nonstented, dismembered pyeloplasty. Renal function shows normal during the follow-up periods.
