Abstract
Propose: To deliver a case report of female bladder exstrophy patients who experienced pregnancy until the birth process.
Methods: A 28-year-old woman with a history of bladder exstrophy, which received inadequate treatment during childhood, had bladder shrinkage and uterine prolapse. The patient underwent reconstruction of continent cutaneous stoma and sacrocolpopexy with mesh in her adulthood. She achieved complete continence by intermittent self-catheterization and gained a better quality of life. She later got married and became pregnant. Pregnancy monitoring was done to evaluate the condition of the patient and her fetus. A collaborative team was built to discuss the best option for delivering the procedure. At 38–39 weeks of gestational age, an elective cesarian section was performed to deliver the baby.
Results: Despite having a greater risk of complications, a woman with a history of bladder exstrophy could undergo pregnancy and give birth. The choice of delivery, either vaginal or cesarean section, is feasible for delivery.
Conclusions: An adult female with bladder exstrophy underwent pregnancy and gave birth. Prior surgery and increased risk of obstetrical complications must be considered.

Abstract
Bladder exstrophy (BE) is a rare, lower ventral midline defect with the bladder and part of the urethra exposed. The etiology of BE is unknown but thought to be influenced by genetic variation with more recent studies suggesting a role for rare variants. As such, we conducted paired-end exome sequencing in 26 child/mother/father trios. Three children had rare (allele frequency ≤ 0.0001 in several public databases) inherited variants in TSPAN4, one with a loss-of-function variant and two with missense variants. Two children had loss-of-function variants in TUBE1. Four children had rare missense or nonsense variants (one per child) in WNT3, CRKL, MYH9, or LZTR1, genes previously associated with BE. We detected 17 de novo missense variants in 13 children and three de novo loss-of-function variants (AKR1C2, PRRX1, PPM1D) in three children (one per child). We also detected rare compound heterozygous loss-of-function variants in PLCH2 and CLEC4M and rare inherited missense or loss-of-function variants in additional genes applying autosomal recessive (three genes) and X-linked recessive inheritance models (13 genes). Variants in two genes identified may implicate disruption in cell migration (TUBE1) and adhesion (TSPAN4) processes, mechanisms proposed for BE, and provide additional evidence for rare variants in the development of this defect.

Abstract
The bladder exstrophy-epispadias complex (BEEC) is an abdominal midline malformation comprising a spectrum of congenital genitourinary abnormalities of the abdominal wall, pelvis, urinary tract, genitalia, anus, and spine. The vast majority of BEEC cases are classified as non-syndromic and the etiology of this malformation is still unknown. This review presents the current knowledge on this multifactorial disorder, including phenotypic and anatomical characterization, epidemiology, proposed developmental mechanisms, existing animal models, and implicated genetic and environmental components.

Abstract
Abstract Ectopia vesicae, or bladder exstrophy, is a rare malformation, more frequently found in males. Very few cases of pregnancy with unrepaired ectopia vesicae have been reported in literature. The majority of these pregnant women with ectopia vesicae have terminated their pregnancies by cesarean section due to malpresentation, preterm labor or other indications. Clemetson concluded that cesarean section was the preferable method of term delivery to avoid postpartum prolapse. We have a different opinion on this because we had an interesting case. A woman with unrepaired ectopia vesicae had two successful vaginal deliveries, in 2009 and 2019 respectively. She recovered well and did not have any symptoms or signs of pelvic organ prolapse (POP) so far. Case presentation Let us present this woman with ectopia vesicae who had four pregnancies; two spontaneous abortions and two vaginal deliveries. In 2009, she had a successful vaginal delivery at Yantai Harbor Hospital where the first author worked at that time. She met the first author again surprisingly, during her third trimester in 2019. She had a spacious pelvis and pendulous abdomen. In this fourth pregnancy, the fetus changed its presentation frequently. Still, she had the second vaginal delivery successfully. She recovered fully after delivery and did not have any symptoms or signs of POP. As far as we know, this is the first case that a patient with ectopia vesicae who has been observed for such a long time after multiple vaginal deliveries. Conclusions Doctors must evaluate the risk of vaginal delivery or cesarean section and consider maternal-neonatal health. Prior to this, women with repaired or unrepaired ectopia vesicae usually delivered their babies by cesarean section. Our practice shows that vaginal delivery is also a safe and feasible choice for some of these patients, especially for those with unrepaired, mild types of ectopia vesicae who experience no other dangerous or uncomfortable symptoms.

Abstract
PURPOSE Isolated classic bladder exstrophy (CBE) is the most common variant of the bladder-exstrophy-epispadias complex (BEEC). The BEEC represents a spectrum ranging from isolated epispadias over CBE to the most severe form, cloacal exstrophy. We report on a series of 12 cases with CBE diagnosed prenatally and illustrate the spectrum of prenatal ultrasound findings with comparison to prior published reports on this entity. METHODS This was a retrospective study involving 12 fetuses with CBE at two large tertiary referral centers in Germany over a 14-year period (2004-2018). RESULTS Median diagnosis was made with ultrasound in 24 + 5 (IQR25,75: 21 + 2, 29 + 0) weeks of gestation. All fetuses presented with the pathognomonic findings non-visualization of the fetal bladder and protruding abdominal mass below the umbilical cord insertion. All fetuses showed normal kidney anatomy and normal amniotic fluid throughout pregnancy. Epispadia was visible prenatally on ultrasound in 6/8 male fetuses. 1/12 Parents opted for termination of pregnancy, 11/12 fetuses were live born and received reconstructive surgery. CONCLUSIONS Isolated CBE is an extremely rare prenatal sonographic finding. Prenatal diagnostics should exclude additional malformations within the spectrum of cloacal malformations.

Abstract
The Bladder-Exstrophy-Epispadias Complex (BEEC) represents the severe end of the uro-rectal malformation spectrum, and has a profound impact on continence, and on sexual and renal function. While previous reports of familial occurrence, in-creased recurrence among first-degree relatives, high concordance rates among monozygotic twins, and chromosomal aberra-tions were suggestive of causative genetic factors, the recent identification of copy number variations (CNVs), susceptibility regions and genes through the systematic application of array based analysis, candidate gene and genome-wide association studies (GWAS) provide strong evidence. These findings in human BEEC cohorts are underscored by the recent description of BEEC(-like) murine knock-out models. Here, we discuss the current knowledge of the potential molecular mechanisms, mediating abnormal uro-rectal development leading to the BEEC, demonstrating the importance of ISL1-pathway in human and mouse and propose SLC20A1 and CELSR3 as the first BEEC candidate genes, identified through systematic whole-exome sequencing (WES) in BEEC patients.

Abstract
Purpose: The Bladder Exstrophy-Epispadias Complex (BEEC) is the most serious form of midline abdominal malformation. The etiology of BEEC is unknown and is thought to be multifactorial. Methylenetetrahydrofolate reductase (MTHFR) polymorphism C677T is strongly associated with other midline abnormalities such as neural tube defects. No proper case-control study existed comparing MTHFR polymorphism with BEEC. We sought to find an association with MTHFR polymorphism and patients with bladder exstrophy (BE). Materials and Methods: The design of the study was a case-control study, involving 50 children with BEEC and 50 normal healthy school children. Genetic analysis for MTHFR 677 polymorphism was carried out after DNA extraction and polymerase chain reaction amplification. Epidemiological analysis was done by using the birth defect questionnaire on parents of BEEC. Results: Forty-two classical BE, two cloacal exstrophies (CE), four epispadias, and two exstrophy variant patients were a part of this study. Severe variety of BE had a significant association with C667T MTHFR polymorphism as compared to the normal control population (P = 0.01). Conclusion: C677T MTHFR polymorphism has a strong association with severe variety (CE) of BEEC occurrence.

Abstract
The bladder exstrophy-epispadias complex (BEEC) represents the severe end of the uro-rectal malformation spectrum, and is thought to result from aberrant embryonic morphogenesis of the cloacal membrane and the urorectal septum. The most common form of BEEC is isolated classic bladder exstrophy (CBE). To identify susceptibility loci for CBE, we performed a genome-wide association study (GWAS) of 110 CBE patients and 1,177 controls of European origin. Here, an association was found with a region of approximately 220kb on chromosome 5q11.1. This region harbors the ISL1 (ISL LIM homeobox 1) gene. Multiple markers in this region showed evidence for association with CBE, including 84 markers with genome-wide significance. We then performed a meta-analysis using data from a previous GWAS by our group of 98 CBE patients and 526 controls of European origin. This meta-analysis also implicated the 5q11.1 locus in CBE risk. A total of 138 markers at this locus reached genome-wide significance in the meta-analysis, and the most significant marker (rs9291768) achieved a P value of 2.13 × 10-12. No other locus in the meta-analysis achieved genome-wide significance. We then performed murine expression analyses to follow up this finding. Here, Isl1 expression was detected in the genital region within the critical time frame for human CBE development. Genital regions with Isl1 expression included the peri-cloacal mesenchyme and the urorectal septum. The present study identified the first genome-wide significant locus for CBE at chromosomal region 5q11.1, and provides strong evidence for the hypothesis that ISL1 is the responsible candidate gene in this region.

Abstract
Bladder exstrophy-epispadias complex (BEEC), the severe end of the urorectal malformation spectrum, has a profound impact on continence as well as sexual and renal functions. It is widely accepted that for the majority of cases the genetic basis appears to be multifactorial. Here, we report the first study which utilizes genome-wide association methods to analyze a cohort comprising patients presenting the most common BEEC form, classic bladder exstrophy (CBE), to identify common variation associated with risk for isolated CBE. We employed discovery and follow-up samples comprising 218 cases/865 controls and 78 trios in total, all of European descent. Our discovery sample identified a marker near SALL1, showing genome-wide significant association with CBE. However, analyses performed on follow-up samples did not add further support to these findings. We were also able to identify an association with CBE across our study samples (discovery: P = 8.88 × 10(-5); follow-up: P = 0.0025; combined: 1.09 × 10(-6)) in a highly conserved 32 kb intergenic region containing regulatory elements between WNT3 and WNT9B. Subsequent analyses in mice revealed expression for both genes in the genital region during stages relevant to the development of CBE in humans. Unfortunately, we were not able to replicate the suggestive signal for WNT3 and WNT9B in a sample that was enriched for non-CBE BEEC cases (P = 0.51). Our suggestive findings support the hypothesis that larger samples are warranted to identify association of common variation with CBE.

Abstract
Chromosome aberrations or genetic syndromes associated with cloacal-bladder exstrophy complex have rarely been reported. The aim of this report is to describe a 14 year-old female Brazilian patient with a complex urogenital malformation, short stature, lack of secondary se-xual characteristics and Y chromosome aberration. A girl with cloacal bladder exstrophy complex was referred for evaluation of short stature and absence of secondary sexual characteristics. Pre-pubertal levels of gonadotropins and sex steroids were observed at the beginning of monitoring, but follow-up showed a progressive increase in testosterone levels. The patient underwent gonadectomy and testicular tissue was identified without dysgenetic characteristics. She had a 46,X,inv(Y)(p11.1q11.2) karyotype, normal SRY sequence, and no Y deletions. The pericentric inversion of Y chromosome apparently did not contribute to the development of the complex urogenital malformation in this patient. Currently, no teratogenic agent, environmental factor, or defective genes have been recognized as etiologic factors for this type of urogenital malformation.

Abstract
Bladder exstrophy (BE) is a complex congenital anomaly characterized by a defect in the closure of the lower abdominal wall and bladder. We aimed to provide an overview of the literature and conduct an epidemiologic study to describe the prevalence, and maternal and case characteristics of BE. We used data from 22 participating member programs of the International Clearinghouse for Birth Defects Surveillance and Research (ICBDSR). All cases were reviewed and classified as isolated, syndrome, and multiple congenital anomalies. We estimated the total prevalence of BE and calculated the frequency and odds ratios for various maternal and case characteristics. A total of 546 cases with BE were identified among 26,355,094 births. The total prevalence of BE was 2.07 per 100,000 births (95% CI: 1.90-2.25) and varied between 0.52 and 4.63 among surveillance programs participating in the study. BE was nearly twice as common among male as among female cases. The proportion of isolated cases was 71%. Prevalence appeared to increase with increasing categories of maternal age, particularly among isolated cases. The total prevalence of BE showed some variations by geographical region, which is most likely attributable to differences in registration of cases. The higher total prevalence among male cases and older mothers, especially among isolated cases, warrants further attention.

Abstract
OBJECTIVES The purpose of this study was to establish in utero reference ranges for the fetal umbilical cord insertion-to-genital tubercle length in early gestation. METHODS A prospective cross-sectional study was performed on 140 normal low-risk singleton pregnancies between 12 and 18 weeks' gestation. The umbilical cord insertion-to-genital tubercle length was measured in a midsagittal section with high-resolution transvaginal or transabdominal sonography. The mean and 95% prediction limits were defined for each gestational week and analyzed by regression equations and correlation coefficients. RESULTS Adequate measurements were obtained in 134 patients. The umbilical cord insertion-to-genital tubercle length as a function of gestational age was expressed by the following regression equation: umbilical cord insertion-to-genital tubercle length = -3.079452 + 1.09 × week (R(2) = 0.7117). The correlation R(2) = 0.7117 was found to be highly statistically significant (P < .001). The normal mean and 95% prediction limits were defined for each gestational week. During the study period, 2 cases were referred to our unit because of nonvisualization of the urinary bladder. The umbilical cord insertion-to-genital tubercle lengths in these cases were below the 95th percentile, confirming the diagnosis of bladder exstrophy. CONCLUSIONS The normative data established in this study may be helpful for early pre-natal diagnosis congenital bladder exstrophy.

Abstract
Exstrophy-epispadias complex (EEC) represents a spectrum of genitourinary malformations ranging in severity from epispadias (E) to classical bladder exstrophy (CEB) and exstrophy of the cloaca (EC). Depending on severity, EEC may involve the urinary system, musculoskeletal system, pelvis, pelvic floor, abdominal wall, genitalia, and sometimes the spine and anus. Prevalence at birth for the whole spectrum is reported at 1/10,000, ranging from 1/30,000 for CEB to 1/200,000 for EC, with an overall greater proportion of affected males. EEC is characterized by a visible defect of the lower abdominal wall, either with an evaginated bladder plate (CEB), or with an open urethral plate in males or a cleft in females (E). In CE, two exstrophied hemibladders, as well as omphalocele, an imperforate anus and spinal defects, can be seen after birth. EEC results from mechanical disruption or enlargement of the cloacal membrane; the timing of the rupture determines the severity of the malformation. The underlying cause remains unknown: both genetic and environmental factors are likely to play a role in the etiology of EEC. Diagnosis at birth is made on the basis of the clinical presentation but EEC may be detected prenatally by ultrasound from repeated non-visualization of a normally filled fetal bladder. Counseling should be provided to parents but, due to a favorable outcome, termination of the pregnancy is no longer recommended. Management is primarily surgical, with the main aims of obtaining secure abdominal wall closure, achieving urinary continence with preservation of renal function, and, finally, adequate cosmetic and functional genital reconstruction. Several methods for bladder reconstruction with creation of an outlet resistance during the newborn period are favored worldwide. Removal of the bladder template with complete urinary diversion to a rectal reservoir can be an alternative. After reconstructive surgery of the bladder, continence rates of about 80% are expected during childhood. Additional surgery might be needed to optimize bladder storage and emptying function. In cases of final reconstruction failure, urinary diversion should be undertaken. In puberty, genital and reproductive function are important issues. Psychosocial and psychosexual outcome depend on long-term multidisciplinary care to facilitate an adequate quality of life.

Abstract
OBJECTIVE The bladder exstrophy-epispadias complex (BEEC) describes a rare anterior midline defect with variable expression involving the infra-umbilical abdominal wall, including the pelvis, urinary tract and external genitalia. It is assumed that the underlying cause of BEEC is a multifactorial mode of inheritance; however, its aetiology remains unknown. Only a few BEEC patients with distinctive cytogenetic features such as numeric or structural chromosomal abnormalities have been reported. The observation of translocations concerning the region of chromosome 9q32-q34.1 in two patients implies that this region bears a candidate gene which, during early blastogenesis, governs the development of this primary field. In this context, we considered the suppressor of variegation, enhancer of zeste and Trithorax (SET) gene, located at chromosome 9q34, to be a good candidate, as the protein encoded is involved in the regulation of cell proliferation and differentiation. Moreover, SET expression was detected in embryonic kidney. MATERIAL AND METHODS A total of 33 patients affected with BEEC were analysed for mutations in the SET gene. RESULTS SET analysis did not reveal either a mutation or the presence of four single-nucleotide polymorphisms (dbSNP124) already described in the database. CONCLUSIONS The data obtained in this study most likely exclude the SET gene as a possible genetic cause of BEEC. Hence, other genes in this region may contribute to the development of this midline defect.

Abstract
OBJECTIVE Exstrophy of the bladder (EB) is part of the bladder-exstrophy-epispadias complex (BEEC). Because familial occurrence of BEEC is rare, exogenous factors are thought to play a major role in the etiology of most BEEC cases. We aimed to investigate a possible genetic basis of BEEC in a consanguineous kindred of Moroccan origin with three members showing the same phenotypic expression of BEEC. PATIENTS AND METHODS The three affected males (two cousins and their maternal uncle) all presenting with nonsyndromic classic EB, were born in Morocco or The Netherlands. One Moroccan patient had an open bladder surface for 22 years due to late surgical reconstruction, avoided upright posture and developed severe lumbar scoliosis. Because three maternally related males from a consanguineous family living in different environments are affected, a genetic basis for EB is likely in this family. To screen for chromosomal aberrations and micro-aberrations in the two patients who were still alive, conventional karyotyping and array-based comparative genomic hybridization (array-CGH) were used on DNA-microarrays with a genome-wide average resolution of <0.5 Mb. RESULTS Chromosome banding revealed normal karyotypes. By array-CGH, one of 8000 clones was aberrant in both affected cousins. This clone from 1p21.1 contained the AMY1B, AMY2B, AMY2A genes coding for salivary and pancreatic amylases. CONCLUSION The aberration detected by array-CGH in both affected cousins is a known copy-number variant and most likely unrelated to the EB-phenotype. Nevertheless, in this family the nonsyndromic EB could be a monogenic disorder inherited in an autosomal-recessive or X-linked fashion.

Abstract
In most children or premenopausal women who need urinary diversion, the underlying disease is benign. After the problems associated with urinary incontinence have been resolved, and patients have reached puberty, sexuality and fertility become more significant. In women with urinary diversion, numerous influencing factors exist, including, but not limited to, the underlying disease and form of urinary diversion. The authors' center has a large expertise in urinary diversion, although the number of cases with pregnancies is limited. This article uses this prior experience and data from a literature review to provide guidance for urologists, obstetricians, general practitioners, and patients to aid decision making in pregnancies after urinary diversion.

Abstract
The bladder exstrophy and classic epispadias represent a spectrum of congenital anomalies with different degrees of anterior midline defect. Although the anomaly usually occurs sporadically there are some cases indicative of a strong genetic component. We present the clinical data of two siblings with bladder exstrophy and epispadias complex (BEEC), who were the product of consanguineous union. All previous reports of familial BEEC in the literature have been reviewed.

Abstract
The bladder exstrophy and epispadias complex (BEEC) is an anterior midline defect with variable expression involving the infraumbilical abdominal wall including the pelvis, urinary tract, and external genitalia. The incidence varies with regard to ethnical background, sex, and phenotypic expression, and an incidence of 1:20,000 to 1:80,000 has been observed in the middle European population. No gene defect has been attributed to BEEC thus far and chromosomal aberrations or genetic syndromes associated with BEEC have only rarely been reported. According to epidemiological data, a complex genetic as well as a multifactorial mode of inheritance could underlie BEEC. However, no single teratogenic agent or environmental factor has been identified, which could play a dominant role in the expression of the BEEC.A risk of recurrence of 0.5-3% has been described in families with one affected subject. These values correspond to an increased recurrence risk estimated to be as high as 200- to 800-fold when compared to the common population. Due to the paucity of affected sib pairs and suitable multiplex families, conventional linkage analysis to identify candidate genes causally related with BEEC appears to be unfeasible. Large association studies and consecutive linkage disequilibrium mapping should therefore lead to the identification of candidate genes. Also new methods including matrix-based comparative genomic hybridization (CGH) are promising and have successfully been used in the past (e.g., CHARGE association). Moreover, the low incidence of the BEEC requires close cooperation between clinicians in the operative and nonoperative specialties as well as geneticists for successful gene search.

Abstract
OBJECTIVE To identify genetic and nongenetic factors contributing to the risk of bladder exstrophy-epispadias complex (BEEC). PATIENTS AND METHODS In all, 285 families with BEEC were invited to participate in the study, and 232 of them were recruited. Epidemiological information was obtained from 151 of the consenting families, with a detailed clinical genetic examination of 94 probands. In all, 440 DNA samples were collected from 163 families for molecular analysis. RESULTS Most of the cases were sporadic and had no family history of BEEC. Among patients, 95% were Caucasian, and males were more common in both the epispadias group (M/F, 2.2, 29 patients) and the classic bladder-exstrophy group (M/F 1.8, 164), but in the cloacal exstrophy group the sex ratio was close to unity (1.1, 15). There was a statistically significant association with advanced parental age (P < 0.001). Birth weight, gestational age and maternal reproductive history did not appear to be significantly different from those in the general population. Information on exposures to tobacco, alcohol and drugs was collected but none appeared to act as a risk factor. Karyotype analysis on 37 cases detected two chromosomal abnormalities, i.e. 46XY t(8;9)(p11.2; q13) and 47XYY. Molecular analysis of the HLXB9 gene, which causes Currarino syndrome, did not detect mutations in the blood or bladder DNA of 10 patients with bladder or cloacal exstrophy. CONCLUSIONS BEEC most commonly occurs as an isolated sporadic birth defect with a recurrence risk of << 1%. There was no evidence of a single-gene effect or common environmental factor in this study population. In addition to race and advanced parental age, birth order may be a risk factor for BEEC. We suggest somatic mutations in a gene(s) within the pathway regulating bladder development may be the cause of BEEC.

Abstract
Clustering of the bladder exstrophy and epispadias complex (BEEC) has been described in 29 families. To explore the genetic contribution we located new families through the German and Austrian Bladder Exstrophy Support Group and the Association for the Bladder Exstrophy Community (predominantly US and Canada). We report six new families with two occurrences of BEEC, one family where the proband is the product of a consanguineous union, and four discordant twin pairs. In conjunction with the published clinical and epidemiological reports this collection suggests that there is a significant genetic predisposition for susceptibility to the BEEC. It also highlights the importance of self-referral groups for recruiting families for multicenter collaborative research efforts to identify susceptibility loci.

Abstract
Exstrophy of the bladder (EB) and exstrophy of the cloaca (EC) are generally recognizable as distinct clinical entities. In patients with EB, the posterior bladder wall is exposed through a midline defect of the abdomen. The umbilicus is inferiorly displaced and located close to the superior margin of the exstrophic bladder. Genital abnormalities are common in boys and girls who may present epispadias and a small, split phallus or a split clitoris, a bifid uterus, and a duplicate or exstrophic vagina. In contrast to classic EB, EC is commonly associated with omphalocele, spinal defects, and incompletely formed external genitalia and is always associated with imperforate anus. Some authors state that EC and EB constitute two distinct disorders, but others consider them part of a "continuum," representing different levels of severity within the same spectrum. The use of the acronym OEIS to refer to the combination of omphalocele, exstrophy, imperforate anus, and spinal defects, in our opinion, has not helped to clarify the clinical definition, pathogenesis, or cause of this multiple congenital anomaly (MCA) pattern, mostly because the term makes no distinction between EC or EB. Here we present the epidemiological analysis of a group of characteristics in infants with EC and infants with EB to determine if they constitute two different entities. We also analyze if the different combinations of omphalocele, imperforate anus, and spinal defects are more frequent in infants with EC than in infants with MCA patterns other than EC and EB. The prevalence in our data for EC was 1:200,233 live births and 1:35,597 for EB. The clinical analysis indicated that the study defects (omphalocele, spine defects, spina bifida, and imperforate anus) tend to occur together in the same child with a higher frequency if the child has the EC defect than in infants with MCA patterns that did not include EC or EB. Our findings of low birth weight, twinning, single umbilical artery, and preferentially associated malformations suggest that EC is the result of damage occurring very early in development and that EC and EB are two different expressions of a primary polytopic developmental field defect.

Abstract
Bladder exstrophy is a very rare congenital anomaly characterized by the exteriorization of the viscera on the abdominal surface, low insertion of the umbilical cord, divergent pubic rami and abnormal exterior genitalia. We report a case of prenatal diagnosis of fetal bladder exstrophy in which the urachus resembled the normal bladder. Considering that non-visualization of the bladder is one of the main findings in cases of bladder exstrophy, special attention should be given to fetal lower abdominal cystic images in order to differentiate them from a normally positioned fetal bladder. A review of the literature together with a sonographic study of the urachus is provided.

Abstract
The authors report three cases of pregnancy in women treated for bladder exstrophy. Based on a review of the literature, and the follow-up of these cases, the aim of this study was to determine the prognosis of pregnancy, which is currently possible due to the progress in antibiotherapy and surgery. Nevertheless, these pregnancies need to be carefully followed-up, not only because of the complications that may occur to the mother and the infant, but also because of the type of delivery involved.

Abstract
Congenital bladder exstrophy affects 1 in 125,000 to 250,000 females. Consisting of absence of the anterior abdominal wall with exposure of the ureteral orifices, failure of pubic symphysis fusion, and deficient anterior pelvic diaphragm musculature, bladder exstrophy is frequently associated with genital prolapse. Pregnancy may be complicated by recurrent urinary tract infections, preterm labor, mild procidentia, and malpresentation. Due to the rarity of the condition, there is a corresponding scarcity of obstetric literature regarding management during pregnancy. We report the case of a young woman with surgically repaired bladder exstrophy who developed genital prolapse. The uterus was suspended using a sacral colpopexy utilizing a Gore-Tex graft. Subsequently, the patient became pregnant and delivered a healthy male infant at 35 weeks' gestation via cesarean section (without recurrence of the genital prolapse postpartum). Sacral colpopexy to correct genital prolapse associated with bladder exstrophy may preserve fertility in young patients.

Abstract
Bladder exstrophy remains one of the most challenging problems in pediatric urology. Recent efforts have focused on primary reconstruction rather than urinary diversion to treat exstrophy. Complete primary closure appears to offer improved continence and decreases the number of surgical procedures required to treat exstrophy.

Abstract
We report on a patient with an ectopic urethra opening into a septate vagina which was distended with urine. The anus and rectum were normal but separated from the urogenital sinus by a thin septum. After surgical repair the patient did well with the exception of recurrent urinary tract infections. At 16 years, she delivered a healthy boy by Cesarean section but miscarried a subsequent pregnancy 3 years later. The 12-13 week female fetus lacked a urethra and had an atretic vagina and cloacal anomalies consistent with a urorectal septum developmental defect. This report provides evidence that cloacal anomalies resulting from the improper development of the urorectal septum may have a genetic cause. Furthermore, we support the proposition previously set forth by Allen and Husmann [J Urol 145:1034-1039, 1991] that such anomalies be referred to as urorectal septal defects rather than cloacal anomaly variants. This terminology accurately represents the developmental defect and clearly distinguishes them from cloacal exstrophies, which are due to the abnormal development of the cloacal membrane and the subumbilical ventral abdominal wall.

Abstract
Exstrophy-epispadias complex has been a difficult disease to treat. As in the minds of the public and most physicians alike, these children are crippled with life-long ailments and multiple operations. Much of the morbidity of this condition relates to failure to preserve urogenital tract function in these children. In recent years, through better understanding of the exstrophic anatomy and improved surgical techniques, complete repair of the exstrophic anomaly has become possible as soon as the child is born. Results of such closure indicate that such repair is not only feasible but mandatory for a successful outcome. Continence rate and cosmetic appearance are superior to the conventional 3-stage technique. Such repair is also socially acceptable as the parents will bring home a normal-looking baby with much fewer operations expected in the future. It is anticipated that complete one-stage exstrophy closure in the newborn period will revolutionize the outcome of all exstrophy patients.

Abstract
Bladder exstrophy is one of the most challenging congenital urinary tract abnormalities. Apart from the open bladder the patient also has various other abnormalities, including urogenital, musculoskeletal and anorectal defects. The size of the exstrophic bladder varies from patient to patient. In the female the clitoris to bifid and the vagina is anteriorly placed. In this paper various aspects of female bladder exstrophy are reviewed in detail, including incidence, etiology, anatomy and clinical features, together with early, medium-term and long-term surgical management. The aim is to achieve a functional bladder closure, although some patients are better off with a urinary diversion. Considering the complexity of the urogenital problems and the surgical management thereof, all patients require lifelong follow-up.

Abstract
We report on a patient with renal cystic dysplasia, whose mother was given gentamicin and corticosteroids early in pregnancy. We speculate that these drugs may be implicated in abnormal nephrogenesis in humans. This speculation is based on gentamicin-induced small kidneys (oligonephronia) in the rat. Renal cystic disease has been demonstrated following glucocorticoid administration early in gestation. We realize that there is no proof for a casual relationship between gentamicin and/or glucocorticoids in the pathogenesis of this patient's renal disease. However, it is possible that renal cystic dysplasia in humans is not solely the result of a genetic defect.
