OBJECTIVE: To investigate the best criteria for discriminating fetuses with isolated posterior urethral valves from those theoretically not eligible for fetal treatment because of complex megacystis, high chance of spontaneous resolution, and urethral atresia. METHODS: A retrospective national study was conducted in fetuses with megacystis detected before 17 weeks' gestation (early megacystis). RESULTS: In total, 142 cases with fetal megacystis were included in the study: 52 with lower urinary tract obstruction, 29 with normal micturition at birth, and 61 with miscellaneous syndromal associations, chromosomal and multiple structural abnormalities (complex megacystis)...

OBJECTIVES: To determine a model of fetal urine biochemical markers to differentiate megacystis microcolon intestinal hypoperistalsis syndrome (MMIHS) from other megacystis. METHOD: Retrospective study of biochemical analysis of fetal urine in patients who presented prenatally with megacystis. We studied β2-microglobulin, sodium, calcium, and phosphorus. Twenty-six patients subsequently diagnosed with MMIHS were compared with two control groups: one of end-stage renal failure (ESRF, 64 fetuses) and the second of "good" postnatal renal function (control group, 64 fetuses)...

OBJECTIVE: To evaluate the best management of fetal megacystis diagnosed in the first trimester and define the prognosis and the most appropriate follow-up as early as possible. METHODS: This is a retrospective study of first-trimester fetal megacystis diagnosed in pregnant women who performed a combined screening for fetal aneuploidy. Megacystis was defined as a longitudinal bladder diameter (LBD) greater than 7 mm. All fetuses were divided into two groups according to the LBD: Group A with LBD > 15 mm and Group B with LBD < 15 mm...

Background: Connatal urinary ascites is rare in females without associated malformations and occurs following bladder rupture. Case Presentation: A female very preterm was delivered by caesarean section because of abnormal Doppler findings. The mother suffered from viral pneumonia requiring intensive care in the third trimester of pregnancy. Serial fetal ultrasound examinations showed a megacystis and ascites. Postnatally, pronounced isolated ascites was drained and its urinary nature was confirmed...

RATIONALE: The pathogenesis of fetal megacystis is divided into obstructive and nonobstructive. Megacystis combined with chromosomal abnormalities is rare and most of the cases are nonobstructive. PATIENT CONCERNS: The fetus showed posterior urethral obstructive megacystis with features of bladder enlargement, "keyhole" feature, and thick bladder wall. DIAGNOSES: Here, we present a case of fetal megacystis diagnosed by ultrasound at pregnancy week 15+2 and with multisystem abnormalities...

BACKGROUND: Fetal megacystis is a sonographic feature that may be indicative of several underlying pathologies. Despite advances in diagnosis and management, the overall prognosis of affected fetuses remains poor and about 50% of such pregnancies are terminated. AIMS: To define the frequency, management, survival and renal outcomes of fetal megacystis over nine years at Wellington Hospital, New Zealand. MATERIALS AND METHODS: A nine-year retrospective review of fetuses with an antenatal diagnosis of megacystis was undertaken...

Megacystis-microcolon-intestinal hypoperistalsis syndrome (MMIHS) is a rare disease of functional obstruction affecting the bladder and intestines, characterized by a markedly distended bladder, microcolon, and decreased or absent intestinal peristalsis. Afflicted neonates have very poor prognosis, usually with fatal outcomes in first days to months of life. Placental fetal thrombotic vasculopathy (FTV) is a thrombo-occlusive disorder of the chorionic plate and fetal circulation. Herein, we describe an undocumented association of MMIHS and placental FTV...

OBJECTIVES: Fetal lower urinary tract obstruction (LUTO), most often associated with presence of posterior urethral valves, poses high risk of perinatal mortality or postnatal renal failure. Looking for a method of causative treatment we have devel-oped a technique of fetal urethroplasty with a coronary angioplasty balloon catheter inserted under an ultrasonographic guidance via an 18-gauge needle introduced transabdominally to fetal bladder. MATERIAL AND METHODS: We have used this procedure in three women with singleton pregnancies (two primiparas and one multipara, 32-35 years of age), diagnosed with fetal megacystis at 12-16 weeks of gestation...

OBJECTIVE: Fetal megacystis has a poor prognosis. During the first trimester, it is frequently associated with chromosomal abnormalities or multiple malformations, but can also be isolated and resolve spontaneously. In this study, our main objective was to determine the fetal and pediatric prognosis in this particular situation. METHODS: This was a retrospective multicenter study. We describe the cases referred to our fetal medicine centers and also cases previously reported in the international literature...

OBJECTIVES: The main aim of this study was to assess the proportion and type of congenital anomalies, both structural and chromosomal, that can be detected at an early scan performed at 12-13 weeks' gestation, compared with at the 20-week structural anomaly scan offered under the present screening policy. Secondary aims were to evaluate the incidence of false-positive findings and ultrasound markers at both scans, and parental choice regarding termination of pregnancy (TOP). METHODS: Sonographers accredited for nuchal translucency (NT) measurement were asked to participate in the study after undergoing additional training to improve their skills in late first-trimester fetal anatomy examination...

A 34-year-old para V woman was referred to our centre at 35+1 weeks of gestation for an assumed fetal malformation with prenatal renal impairment and anhydramnios. Prenatal ultrasound demonstrated unilateral renal agenesis; the bladder was not detectable. The baby was born by caesarian section at 36+2 weeks of gestation because of placental insufficiency. Postnatal adaptation was uneventful, but the newborn presented external stigmas of trisomy 21 and progressive renal impairment with anuria. Nevertheless, the postnatal ultrasound showed two enlarged kidneys in loco typico with impaired perfusion but without signs of malformations...

REVIEW
K Taghavi, C Sharpe, M D Stringer
Fetal megacystis is variably defined and understood. The literature on fetal megacystis was systematically reviewed, focusing on prenatal diagnosis, associations and outcomes. This yielded a total of 18 primary references and eight secondary references. Fetal megacystis has an estimated first-trimester prevalence of between 1:330 and 1:1670, with a male to female ratio of 8:1. In the first trimester, megacystis is most commonly defined as a longitudinal bladder dimension of ≥7 mm. Later in pregnancy, a sagittal dimension (in mm) greater than gestational age (in weeks) + 12 is often accepted...

Monozygotic twins were previously regarded as "identical". By now an increasing number of case reports of monozygotic but discordant twins have been reported, and therefore discordance between monozygotic twins is being investigated intensively. We report a case of female preterm monozygotic twins who were discordant for fetal megacystis due to cloacal dysgenesis. Pregnancy was achieved after intracytoplasmatic sperm injection and transfer of 2 embryos. By the first trimester fetal megacystis with consecutive oligohydramnios and hypoplasia of the lungs was diagnosed...
