We report a case of a woman with a preexisting diabetes insipidus (DI), who had two consecutive uncomplicated pregnancies. Both pregnancies resulted after spontaneous conception and had a similar uneventful course. At the time of conception the patient was receiving 1-desamino-8D-arginine-vasopressin (DDAVP) 30 microg/d which maintained a urinary volume of 2-3 l/day. Pre-existing DI can be handled carefully and result in an uncomplicated pregnancy. In such cases careful monitoring of the patient's fluid balance and liver enzymes, as well as monitoring for pre-eclampsia and oligohydramnios during pregnancy are essential.

We report a case of subclinical central diabetes insipidus (DI), due to Rathke's cleft cysts, that was initially misdiagnosed as transient DI of pregnancy because it presented in the third trimester of pregnancy. A 37-year-old primigravida visited the Department of Obstetrics in the 30th week of gestation due to polyuria. She was admitted due to oligohydramnios; the amniotic fluid index was 3.24. A vasopressin challenge test was performed and her urine osmolality increased by >100% from baseline after the administration of desmopressin. Because central DI or transient DI of pregnancy was suspected, we prescribed her a desmopressin nasal spray. She gave birth to a relatively healthy baby at 37 weeks and 4 days of gestation. Several months after delivery, discontinuation of desmopressin resulted in recurrence of her polyuria. Magnetic resonance imaging of her brain revealed Rathke's cleft cysts, and finally central DI was diagnosed.

Renal tubular dysgenesis (RTD) is the absence or poor development of the renal proximal tubules caused by gene mutations in the renin-angiotensin system. Although RTD has been considered fatal, improving neonatal intensive care management has enhanced survival outcomes. However, little has been reported on the survival of extremely preterm infants. This study reports the survival of an extremely preterm infant with RTD and discusses the appropriate management of RTD by reviewing the literature. A female infant weighing 953 g was delivered at 27 weeks' gestation by Cesarean section because of oligohydramnios. She exhibited severe persistent pulmonary hypertension, severe systemic hypotension, and renal dysfunction shortly after birth. Respiratory management was successfully undertaken using nitric oxide inhalation and high-frequency oscillatory ventilation. Desmopressin was effective in maintaining her blood pressure and urinary output. She was diagnosed with RTD based on genetic testing, which revealed a compound heterozygous mutation in the angiotensin-converting enzyme gene in exon 18 (c.2689delC; p.Pro897fs) and exon 20 (c.3095dupT; p.Leu1032fs). At 2 years, she started receiving oral fludrocortisone for treating persistently high serum creatinine levels, which was attributed to nephrogenic diabetes insipidus caused by RTD. Subsequently, her urine output decreased, and renal function was successfully maintained. Currently, there is no established treatment for RTD. Considering cases reported to date, treatment with vasopressin and fludrocortisone appears to be most effective for survival and maintenance of renal function in patients with RTD. This study presents the successful management of RTD using this strategy in an extremely preterm infant.
