Abstract
During cloacal reconstruction, we consider both common channel (CC) and urethral length when deciding between total urogenital mobilization (TUM) and a urogenital separation (UGS). Our concern about TUM in the case of a short urethra is resultant bladder neck incompetence, while conversion to UGS after completing the TUM dissection may result in urethral injury. Use of an interposition flap harvested from the ischiorectal fossa is another measure we use to prevent potential complications.

Abstract
BACKGROUND Cloaca malformations result from a disproportion of apoptosis, cell growth, and maturation. The range of cloacal malformations is extensive and diverse, with a lack of a straightforward classification system. Cloacal dysgenesis sequence (CDS), also known as urorectal septum malformation sequence, is a rare cloaca variant described as the absence of a perineal orifice. Prenatal magnetic resonance imaging and antenatal ultrasounds may reveal a cloacal malformation; however, many patients are not diagnosed with cloacal malformation until birth. CASE REPORT We present a case of a female neonate delivered by a 23-year-old G2P1T1A0L0 mother who had received comprehensive prenatal care. During pregnancy, bilateral multicystic dysplastic kidneys were identified prenatally, leading to the in utero placement of a vesicoamniotic shunt. The physical exam revealed a distended abdomen with reduced abdominal musculature and laxity, ascites, a vesicoamniotic shunt in place, absent urethra, ambiguous genitalia with no vaginal opening, no perineal opening, and clubfoot. Abdominal radiograph showed findings consistent with significant abdominal ascites. An exploratory laparotomy was performed that included diverting colostomy, mucous fistula creation, tube vaginostomy, removal of the vesicoamniotic shunt, and suprapubic tube placement. The patient recovered well from this operation with no complications. CONCLUSIONS CDS is an uncommon condition in pediatric patients, and although sonographic findings can reveal urinary tract abnormalities, prenatal imaging might not always identify CDS. Our case underscores the uniqueness of the case and the significance of early detection and immediate medical and surgical intervention.

Abstract
INTRODUCTION Cloacal malformation is a rare anomaly that remains a diagnostic challenge prenatally, despite the current advances in ultrasonography and MRI. This condition can in some, present with isolated ascites or with other findings, such as a pelvic cyst or upper urinary tract dilatation. In a minority, the ascites may be progressive, questioning the role of antenatal intervention. METHODS We report on ten patients that have been identified from our Cloaca database between 2010 and 2022. RESULTS The presence of ascites was associated with extensive bowel adhesions and matting, leading to a challenging initial laparotomy and peri-operative course. CONCLUSIONS Antenatal finding of ascites in newborns with cloacal malformations should raise a red flag. The surgeon and anaesthetist should be prepared for the operative difficulties secondary to bowel adhesions and the higher risk of haemodynamic instability at the initial surgery. An experienced team at initial laparotomy in such patients is vital. LEVEL OF EVIDENCE II.

Abstract
INTRODUCTION Total Urogenital Mobilization (TUM) has been the standard surgical approach for the urogenital complex in Cloacal Malformations (CM) since its inception in 1997. Partial Urogenital Mobilization (PUM) in CM remains an under-utilized or under-reported option. The main anatomical difference between TUM and PUM is the division of the pubo-urethral ligaments. OBJECTIVE We explored the feasibility of PUM in a select subset of our patients with CM and report early outcomes. STUDY DESIGN We retrospectively reviewed prospectively collected data of all our CM patients who had primary reconstruction at our centre from 2012 to 2020. We included in our review the patients who underwent PUM. Mullerian abnormalities, spinal cord involvement, common channel length (CC), urethral length (UL), surgical reconstruction, and outcomes including urinary continence, recurrent UTI, ultrasound and preoperative DMSA/MAG3, cystovaginoscopy post-reconstruction, and post-void residuals were noted. RESULTS Fifty-three patients had primary reconstruction, and of these, eleven had a common channel less than 3 cm. Of the eleven, only one underwent TUM. In the PUM group, two underwent filum untethering (20%). Mullerian duplication was noted in 5 patients (50%). The median CC length = 1.6 cm (range = 1.5cm-2.7 cm), and median UL = 1.5 cm (range = 1.5cm-2.5 cm). Follow-up ranged from 9 to 134months (median = 63months). Post-reconstruction all had a separate urethral and vaginal opening on examination and cysto-vaginoscopy. The continence outcomes are summarized in Fig.1. DISCUSSION Although TUM is the most common solution for the urogenital complex in CM, a subset would be suitable for PUM, and this option is under-utilized or under-reported in literature. We presume that many who had TUM probably only needed a PUM, and therefore could report better outcomes from a bladder function aspect. It is important to differentiate the two, and outcomes should be appropriately categorized. Our default approach is a PUM in all CM with less than 3 cm common channel. Only the lateral and posterior aspects of the urogenital complex are mobilized and if the urethra did not reach a satisfactory level for easy intermittent catheterization, then we proceed to a TUM dividing the pubo-urethral ligaments. PUM avoids the potential complications related to dividing the pubo-urethral ligament in TUM. It may also avoid the need for CIC which is encountered in patients who undergo TUM. CONCLUSION PUM is a viable alternative in cloacal malformations with good outcomes in those with a common channel under 3 cm. This of course requires appropriate patient selection and accurate categorization of interventions to understand the true outcomes.

Abstract
INTRODUCTION Long-term outcomes of cloacal malformations remain unclear. We evaluated postoperative bowel control, bladder function and quality of life in patients under 18 years of age with cloaca. MATERIALS AND METHODS This was a multi-center cross-sectional observational study accomplished by the Nordic Pediatric Surgery Research Consortium. Patients with a cloacal malformation, 4-17 years of age, were eligible. Data including patient characteristics, surgical procedures, and complications were retrieved from case records. Established questionnaires with normative control values evaluating bowel function, bladder function, and health-related quality of life (HRQoL) were sent to the patients and their caregivers. The study was approved by the participating center's Ethics Review Authorities. RESULTS Twenty-six (67%) of 39 eligible patients with median age 9.5 (range, 4-17) years responded. Twenty-one (81%) patients had a common channel ≤3 cm. Imaging confirmed sacral anomalies in 11 patients and spinal cord abnormalities in nine. Excluding patients with stoma (n = 5), median bowel function score was 12 [7-19], and 5 patients (20%) reported a bowel function score ≥17, approaching normal bowel control level. Bowel management increased proportion of socially continent school-aged children to 52%. Six (23%) patients had a permanent urinary diversion or used clean intermittent catheterization (CIC), while majority (70%) of the remaining patients were urinary continent. The reported HRQoL was comparable to healthy Swedish children. CONCLUSION Whilst well-preserved spontaneous bowel control was rare, a majority of patients were dry for urine without any additional procedures. Few patients experienced social problems or negative impact on HRQoL due to bladder or bowel dysfunction. LEVEL OF EVIDENCE Level IV.

Abstract
Anomalies of the urogenital sinus, which is a transient feature of the early human embryological development, are rare birth defects. Urogenital sinus abnormalities commonly present as pelvic masses, hydrometrocolpos, or ambiguous genitalia and most commonly occur within the context of congenital adrenal hyperplasia. Anomalies of the urogenital sinus requires surgical repair. We experienced a case of a female newborn with congenital urogenital sinus abnormality in which the early diagnosis helped us to prevent complications by decompressing the vagina soon after birth. Antibiotic prophylaxis was sufficient to avoid infections and to decompress the genitourinary system, thus allowing a deferred elective surgery to correct the sinus.

Abstract
INTRODUCTION/BACKGROUND Although the combination of bladder dysfunction and upper tract anomalies puts patient with cloaca at risk for renal disease, the rarity of this condition makes it difficult to study empirically. As a high-volume center, we uniquely capture bladder function outcomes following our growing number of cloacal repairs. OBJECTIVE 1) Describe the rates of incomplete bladder emptying following primary cloacal repair (at 2-3 months after repair and last follow up), and 2) identify clinical factors associated with assisted bladder emptying. STUDY DESIGN We performed a prospective cohort study of patients undergoing primary cloaca repair by our Children's National Colorectal Center team between 2020 and 2021. The primary outcome was assisted bladder emptying at 2-3 months postoperatively and last visit. Covariables included preoperative characteristics (cloacagram measurements), ARM complexity (moderate = common channel [CC] <3-cm, severe = CC ≥ 3-cm), vesicoureteral reflux (VUR) status, sacral ratio (good ≥0.7, intermediate 0.7-0.4, poor ≤0.4), spinal cord status, means of preoperative bladder emptying, and operative details (age at repair, repair type, & concomitant laparotomy). RESULTS Eighteen participants were eligible. A majority had moderate cloaca (78%), VUR (67%), spinal cord abnormalities (89%), and good sacral ratios (56%). Preoperatively, 10 patients were diapered for urine and 8 had assisted bladder emptying. Surgical repairs were performed at a median age of 8 months (range 4-46). Nine (50%) patients underwent urogenital separation (UGS), eight (44%) total urogenital mobilization, and 1 (6%) perineal sparing posterior sagittal anorectoplasty with introitoplasty. Exploratory laparotomy was performed in 7 (39%) patients. At 2-3 months, 7 patients were voiding and 11 required assisted bladder emptying. Median length of long-term follow up was 12 months (range 5-25), and 8 patients were voiding and 10 required assisted bladder emptying. Postoperative need for assisted bladder emptying was significantly associated with assisted bladder emptying preoperatively, a shorter urethra and increasing common channel length, UGS and exploratory laparotomy. Spinal cord imaging findings were not associated. DISCUSSION Bladder emptying following cloaca repair is likely a result of congenital function and surgical effects. Indeed, increasingly cloaca complexity requiring UGS and laparotomy was associated with both pre- and post-operative assisted bladder emptying. The lack of association with spinal cord imaging may reflect a divergence between anatomy and function. CONCLUSION Approximately half of patients required assisted bladder emptying in this study. Associated factors included urethral and common channel length, the need for assisted bladder emptying preoperatively, the type of surgical approach and additional laparotomy. Being diapered with seemingly normal voiding prior to surgery did not guarantee normal bladder function postoperatively.

Abstract
AIM This study reviewed the literature on the laparoscopic management of cloaca. METHODS A Medline and Embase search was performed for "laparoscopy" and "cloaca." Articles for which full-text in English was not available, duplicate articles, and review articles were excluded. Demographic characteristics, duration of follow-up, length of common channel, postoperative complications, and functional outcomes were analyzed. RESULTS The database search retrieved 81 articles after excluding unrelated articles and identified new articles through cross-referencing 14 articles (72 patients) for this review. The rectal pouch was situated below the pubococcygeal (PC) line in three patients. In all other patients, the rectum was located above the PC line. Only the rectal component of the malformation was repaired laparoscopically in 80% (58/72). Fourteen patients underwent laparoscopic mobilization of the rectum and urogenital component. The length of the common channel was more than 3 cm in all these fourteen patients. The most common complication was rectal prolapse (n = 11). Functional evaluation by Krickenbeck scoring system was reported in 32 patients, of which 6/32 (18.75%) had fecal soiling > Grade 2. DISCUSSION Until recently, laparoscopy for the common cloaca was almost exclusively used in patients with low urogenital sinus with high rectal pouch. Moreover, only the rectal component was repaired laparoscopically. Recently, laparoscopic rectal mobilization and urogenital separation was described for patients with common channel length ≥3 cm. It has been reported that laparoscopic vaginal mobilization is easy and more complete by this technique and may avoid vaginal replacement in most of these patients with the long common channel. However, only two studies have reported this technique, and its reproducibility and long-term results are still awaited. Another interesting observation was the increasing use of urethral length along with common channel length in determining the appropriate procedure for the patients with common cloaca. Recent studies propose that the urogenital separation technique be preferred over urogenital mobilization in patients with the short urethra. Nonetheless, we still don't have long-term comparative data to demonstrate that the functional outcomes are better with this new algorithm. We conclude that the persistent cloaca needs an individualized approach, and laparoscopy can be utilized to mobilize the high rectum and is also helpful for the urogenital separation in patients with common channel length >3 cm. However, at present, there is no conclusive evidence to support that laparoscopic repair has a better functional outcome than the open approach.

Abstract
Persistent cloaca involves fusion of the bladder, vagina, and rectum into a single duct called the common duct. Although its pathogenesis remains unclear, it has been associated with hyperchloremic metabolic acidosis. Herein, we present the case of a neonatal girl with high-confluence type variant of persistent cloaca treated with vesicostomy (Blocksom) for refractory metabolic acidosis. She was diagnosed with persistent cloaca before birth; colostomy was performed and a urinary catheter was placed in the bladder. Voiding cystourethrography on day 19 after birth showed that most of the contrast material leaked into the rectum; hence, the urinary catheter was removed. On day 27, hyperchloremic metabolic acidosis was detected and treatment with oral sodium bicarbonate was initiated; however, the infant showed no response. Because hyperchloremia occurred after removal of the urinary catheter, continuous urine retention in the colon through the common duct was believed to have caused the progression of hyperchloremic metabolic acidosis through transporters in the intestinal mucosa. As reinstallation of a urinary catheter was technically difficult, vesicostomy was performed on day 29, after which the metabolic acidosis improved. This report suggests vesicostomy as an effective treatment for refractory hyperchloremic metabolic acidosis associated with high-confluence type persistent cloaca.

Abstract
Persistent cloaca is a rare and severe variety of anorectal malformation, which is more common in females and includes a spectrum of abnormalities. The urinary tract, genital tract and rectum open into a common channel, which exteriorises as a single perineal opening. We are reporting a patient with a novel variation in the classical anatomy of the cloaca. The child has a short blind-ending colon with a cecovesical fistula associated with mullerian agenesis and lipomyelomeningocoele. The child is being managed in a stepwise approach and she has completed the anal reconstruction. Here, we discuss this novel variation in anatomy and challenges in its management.

Abstract
Persistent cloaca (PC) is the most intricate anorectal malformation. Contrast-enhanced ultrasound (CEUS) is safe for hepatic, renal, splenic, vascular, and intracavitary assessment in children, but it is little applied for cloacal malformation. Our results demonstrate that CEUS can not only display the uterine, vagina, bladder, urethra, rectum, and rectovaginal fistula, but also measure the length of the common channel, bladder neck to the common channel, and distal urethra to the perineum. To our knowledge this may be the first report of preoperative evaluation by CEUS in an infant with PC.

Abstract
STUDY OBJECTIVE Our aim was to use porcine vagina to create a vaginal matrix and test its cellular biocompatibility. DESIGN, SETTING, AND PARTICIPANTS Vagina was harvested from pigs and decellularized (DC) using a combination of detergents (Triton X-100 and sodium deoxycholate) and enzymes (DNAse/RNAse). INTERVENTIONS The presence of cellular material, collagen structural integrity, and basement membrane proteins were assessed histologically. To address cytocompatibility, porcine adipose-derived mesenchymal stem cells were harvested from abdominal fat together with vaginal epithelial cells and seeded onto the mucosal aspect of the vaginal scaffold. Both cell populations were seeded individually and assessed histologically at days 3 and 10. MAIN OUTCOME MEASURES AND RESULTS The combination of enzymes and detergents resulted in a totally acellular matrix with very low DNA amount (control = 97.5 ng/μL ± 10.8 vs DC = 40.1 ng/μL ± 0.33; P = .02). The extracellular matrix showed retention of collagen fibers and elastin and a 50% retention in glycosaminoglycan content (control = 1.18 μg/mg ± 0.28; DC = 1.35 μg/mg ± 0.1; P = .03) and an intact basement membrane (positive for laminin and collagen IV). Seeded scaffolds showed cell attachment with adipose-derived mesenchymal stem cells and vaginal epithelial cells at days 3 and 10. CONCLUSION It is possible to generate an acellular porcine vaginal matrix capable of supporting cells to reconstruct the vagina for future preclinical testing, and holds promise for creating clinically relevant-sized tissue for human application.

Abstract
Permanent communication between the rectum and the vagina along with full thickness of anal sphincter faults can be a result of an unsuccessful primary repair of fourth degree obstetric trauma. This results into complete fecal incontinence and impaired quality of life. Anterior overlapping sphincteroplasty can be chosen as a method of treatment for fecal incontinence due to obstetric injuries. However, large perineal body reconstructions are generally pretty challenging tasks for surgeons. What we will describe here for the repair of a traumatic cloaca, occurred 23 years ago during vaginal delivery, is the use of a transpositional flap following overlapping sphincteroplasty. Anatomic recovery and fecal continence restoration have been accomplished completely by a follow-up of 24 months.

Abstract
Cloacal duplication is an exceedingly rare group of anomalies with a limited number of cases reported so far. The anomaly may be confined to partial bladder duplication or it may involve complete duplication of the urogenital tract, hindgut, spine, lower limbs, and vascular structures. Every case is unique and ought to be approached individually. By means of imaging studies and endoscopy, anatomic details should be carefully defined before endorsing surgical correction. A satisfactory outcome can be achieved in the majority of cases. In this report, we describe 3 girls with cloacal duplication, and review pertinent imaging and surgical management.

Abstract
Sixteen cases of cloacal prolapse in raptors were reviewed in this study. Colonic prolapse was the most common presentation (56% of cases). Red-tailed hawks ( Buteo jamaicensis ) were overrepresented, comprising 66% of colonic prolapse cases. In cases of colonic prolapse, postsurgical stricture formation was a commonly identified complication after resection and anastomosis of the colon. A novel technique was used in 2 cases of colonic prolapse, in which sterile, semirigid rubber tubing was placed in the distal colon and removed per-cloaca at the end of the procedure; this facilitated a secure, fluid-tight anastomosis while maintaining sufficient intestinal lumen. Oviductal prolapse (31% of cases) was associated with the most guarded prognosis (40% treatment success). Cloacoliths were treated successfully in 2 birds (13% of cases) by minimally invasive per-cloacal manual removal.

Abstract
Hydrocolpos presenting at birth in a neonate with a cloacal malformation may lead to massive distension, with compression of adjacent structures. At times, the hydrocolpos requires urgent drainage. Additionally, these neonates need a divided colostomy to divert their fecal stream and prevent genitourinary contamination. We present a novel approach by which these two procedures can be performed as a single operation guided by a combination of cystoscopy, colposcopy, and laparoscopy. This provides a minimally invasive technique with excellent outcome and potentially superior visualization of the necessary intra-abdominal structures.

Abstract
Congenital prepubic sinus is a rare congenital anomaly situated in the midline of the lower abdomen. We report a case of congenital prepubic sinus, closely associated with a urachal remnant. Preoperative magnetic resonance imaging showed clearly that the sinus tracked the urachus caudally. This finding supports the theory that the anomaly is caused by abnormal remnant tissue originating from the cloacal membrane, which tracks the allantois duct caudally along with fetal longitudinal growth.

Abstract
Cloacal dysgenesis sequence (CDS) is a rare and lethal malformation. We report such a case of long-term survival, currently to 12 years of age. In the fetal period, she received a timely placement of vesico-amniotic shunt for a megabladder due to a severe urethral obstruction. Postnatally, cystostomy and colostomy were created because of no perineal opening of urethra, vagina, and anus. Anorectoplasty, construction of efferent conduit, and colostomy closure were performed at 4 years of age. Ileovaginoplasty and ileovesicostomy which was a Mitrofanoff-type of conduit, and labioplasty were performed at the age of 11 years. To the best of our knowledge, only five survivors with CDS over 1 year of age have been reported.

Abstract
Cloacal dysgenesis sequence (CDS) is a severe hindgut malformation occurring in 1:50,000 to 250,000 live births (Qureshi et al. Prenatal diagnosis of cloacal dysgenesis sequence: differential diagnosis from other forms of fetal obstructive uropathy. Fetal Diagn Ther 1998;13:69-74; Bargaje et al. Cloacal dysgenesis sequence. Ann Diagn Pathol 2008;12:62-66). It is characterized by a smooth perineum with no urethral, vaginal, or anal openings, and lack of labioscrotal development. Typically, the bladder, vagina, and colon each end blindly, although persistent cloaca without perineal orifice can be seen. With no egress for urine, infants have renal insufficiency and pulmonary hypoplasia, usually making CDS lethal (Sahinoglu Z et al. The prenatal diagnosis of cloacal dysgenesis in six cases: can the termination of pregnancy always be the first choice? Prenat Diagn 2004;24:10-16). Reported survivors have had a persistent urachus or have been spared the effects of oligohydramnios by the presence of a twin (Liang X. Cloacal dysgenesis sequence: observations in four patients, including three fetuses of second trimester gestation. Pediatr Dev Pathol 1998;1:281-288). We report a case of long-term survival, currently to 25 months of age, and renal transplantation in a monochorionic, diamniotic twin girl with CDS.

Abstract
An 11-year-old female consulted our department with complaints of urinary incontinence and pyuria. She had had a cloacal repair 7 years ago. The radiograph showed four stones in the pelvis. Magnetic resonance imaging showed two diverticula next to the urethra and several low intensity masses in one diverticulum were regarded as stones. Voiding cystourethrography showed normal urinary bladder contraction, although there were residual urine in the diverticula. Preoperatively, these stones were thought to be formed as a result of the long-standing residual urine. Cystourethroscopy showed that the two diverticula existed within the proximal area of the urethral sphincter and four white stones were found in them. Transurethral cystolithotripsy was performed and a surgical staple was found in the core of each stone. The surgical staples had been used for the cloacal repair and they had migrated into the bladder resulted in stone formation. To the best of our knowledge, this is the first report of bladder stones caused by the migration of surgical staples into the bladder after cloacal repair.

Abstract
Cloacal exstrophy, a rare and complex congenital anomaly, presents with omphalocele; exstrophied bilateral hemibladders with ureteric or miillerian remnant orifices; central exstrophied ileocecal bowel plate with superior orifice of the terminal ileum, inferiorly, the colon, and centrally, the appendix; bifid rudimentary external genitalia; separated pubic rami; low-set umbilicus; and epispadias in the classic form. A newborn case of cloacal exstrophy presenting without an exstrophied intestine and vesicointestinal fistula is reported. The clinicopathologic features of this previously unreported variant of cloacal exstrophy are discussed with special emphasis on embryologic basis. Exstrophied bowel is the main component of exstrophy cloaca, which makes our case unique with regard to the absence of exstrophied bowel and vesicointestinal fistula. This well-known fact is not applicable to the present case. We think that some other unknown mechanisms must be at work for the development of the cloacal exstrophic anomaly presenting with a shortened intact colon ending with an anteriorly located anus. Normal development of the hindgut primarily depends on the normal formation of the cloacal membrane. The basic morphogenetic processes that consist of cell deposition, fusion, and merging should achieve the precise balance between cell proliferation and apoptotic cell death both in hindgut and cloacal membrane development. Unsatisfactory explanations of many similar malformations are primarily due to the lack of accurate and illustrative findings in different fields of embryology. The present case confirms that further studies are required to clarify the various theories in order to achieve more satisfactory explanations for these types of rare anomalies.

Abstract
Minimally conjoined omphalopagus twins (MCOTs) has been recognized in the last decade as a special subgroup in which omphalopagus twins have union of peritoneal cavities through anterior lower abdominal wall defect with union of distal small intestine and patent urachal structures and associating anorectal malformation. A careful review of the current literature revealed that MCOTs have usually been separated in emergency situations within the first hours of life due to ruptured omphalocele, gastroschisis, stillbirth of one of the twins, intestinal obstruction, or requirement of enterostomy for cloacal anomaly. Pediatric surgeons should be familiar with MCOTs and ready for emergency separation with thorough knowledge of the anatomical relationships of the connecting structures and the embryologic basis for this anomaly. We present a new set of MCOTs separated in emergency conditions with a review of the relevant English literature. We give special emphasis to the common surgical characteristics and a brief discussion on the embryogenesis of this rare condition.

Abstract
PURPOSE Cloacal exstrophy is rare and it represents a reconstructive challenge. Options for managing the urinary tract include primary closure or approximation of the bladder halves in the midline with later closure. We present our observations and evolving thoughts concerning optimal treatment in these patients. MATERIALS AND METHODS We retrospectively reviewed the records of patients with cloacal exstrophy seen in the last 5 years. Initial management was examined, including complete primary closure vs a staged approach. We noted midline defects, spinal cord abnormalities or other anatomical reasons that precluded primary closure. RESULTS Seven patients, including 5 females and 2 males, were identified. An omphalocele noted in all 7 patients was closed in 5 at initial operation. All underwent preservation of the hindgut in the fecal stream. Spinal cord tethering was noted in 7 of 7 cases. Complete primary bladder closure was performed in 3 of the 7 patients, while the size of the bladder plates or a large abdominal wall defect precluded closure in the remainder. Continence was not achieved in the 3 cases closed primarily. All patients achieving urinary continence underwent bladder neck closure and augmentation cystoplasty with a continent catheterizable channel. CONCLUSIONS Patients with cloacal exstrophy have anatomical issues that can prevent complete primary bladder closure or preclude the achievement of urinary continence. The high incidence of tethered cord places these patients at risk for upper tract changes and bladder decompensation during followup. Despite successful primary closure in 3 of 7 patients all have a tiny bladder and require secondary procedures to become continent. Extensive dissection during the first operation can contribute to more difficult dissection with potential increased morbidity during subsequent surgeries. Therefore, the best initial approach for the typical patient may be closure of the abdominal wall and approximation of the exstrophied bladder halves in the midline. Secondary closure with continent diversion and reconstruction of the external genitalia can be performed at ages 18 to 24 months.

Abstract
Traumatic cloaca is a disabling condition characterized by disruption of the perineal body, anterior sphincter tears and loss of the distal rectovaginal septum. Anterior overlapping sphincteroplasty is the method of choice to treat faecal incontinence caused by obstetric injury. However, reconstruction of large perineal body defects may be a challenging task for surgeons. Herein we describe the successful use of a modified lotus petal flap following overlapping sphincteroplasty to repair a traumatic cloaca that had occurred during vaginal delivery 20 years earlier. After 3 months of follow-up and ileostomy closure, the patient had a good aesthetic result and only minor faecal incontinence episodes not requiring pads, fully recovered urinary continence and a significant improvement in her quality of life.

Abstract
PURPOSE Psychological functioning, as reflected in psychopathology, psychosocial functioning, gender identity, gender role and cognitive abilities, was examined in a sample of patients with cloacal exstrophy. MATERIALS AND METHODS Nine participants 11 to 37 years old completed the evaluation. Standardized measures were used and participant responses were compared to the norms of the various instruments. Gender reassigned participants with cloacal exstrophy were compared with nonassigned participants with cloacal exstrophy. Mean differences between the 2 groups were calculated using the t test. RESULTS Overall the participants with cloacal exstrophy reported good psychological functioning. Significant differences between reassigned and nonassigned participants were found in the area of depression. All participants had a stable gender identity. XY females showed more male-typical gender roles. There were no significant group differences on cognitive assessments. Reassigned and nonassigned participants did not differ in IQ. CONCLUSIONS Although being born with cloacal exstrophy puts patients at risk for psychopathology and psychosocial problems, it does not necessarily mean that these problems will develop. With the appropriate support these patients can have remarkably well adjusted lives.

Abstract
PURPOSE Total urogenital mobilization is deemed to preserve the urogenital sinus blood supply and avoid ischemic complications. We report our experience with this technique for cloacal repair. MATERIALS AND METHODS We retrospectively reviewed all consecutive cases of persistent cloaca managed by total urogenital mobilization via a posterior sagittal approach by a single pediatric urologist between 1998 and 2003. During this period 22 girls (12 with a common channel longer than 3 cm) underwent total urogenital mobilization for cloaca repair (1 redo) at a median age of 10 months (range 2 to 102). A total of 15 procedures (68%) could be completed by a perineal approach only. Four patients with a long common channel required additional maneuvers after mobilization to complete the reconstruction. RESULTS Urethral stenosis was observed in 2 patients after urethral separation from the vagina (1) and common channel retubularization (1). One child with a perineal hemangioma required a redo posterior sagittal anorectoplasty for complete vaginal and anal closure. In addition, 1 case of urethrovaginal fistula was diagnosed on cystovaginoscopy but was asymptomatic, and 1 child with a minor residual common channel underwent urethral revision to allow easier intermittent catheterization. With a median followup of 48 months (range 11 to 162) the latest examination involving endoscopy with anesthesia showed a good result in 17 patients, a tight introitus that might require further surgery in 3 and a minimal residual common channel of 0.5 cm in 2. CONCLUSIONS Total urogenital mobilization is an effective technique for repairing short and long common channels, and a low surgical complication rate can be anticipated.

Abstract
AIM OF STUDY Significant advances have occurred in the management of anorectal malformations, yet many patients still have technical, frequently catastrophic, operative complications that are potentially avoidable. We chose to analyze our experience in patients who have previously undergone a repair which was unsuccessful and required a reoperation, to detect the technical problems that led to complications and to try to establish a set of recommendations to avoid them. METHODS From a series of 1806 cases of anorectal malformations, 212 were reoperated on after a failed procedure done at another institution. The operative reports of the original procedure were analyzed, as well as our own operative findings, in an attempt to understand the causes of the complications. RESULTS We found 303 indications for reoperation, with many patients reoperated on for more than 1 problem. Complications requiring reoperation included stricture or acquired atresia of the rectum (87 patients), mislocated rectum (76), recurrent, persistent, or acquired fistula from the rectum to a neighboring urogenital structure, or to the perineal skin (67), persistent urogenital sinus in cases of cloacas (23), rectal prolapse (21), stricture or acquired atresia of the vagina (16), stricture or acquired atresia of the urethra (8), and persistent cloaca (4). The analysis of the original operative report and/or our operative findings indicated that the most common causes of these complications were (a) insufficient rectal mobilization owing to a dissection performed in a wrong plane, or (b) in the presence of or inadequate colostomy located too distally, (c) a tense anastomosis owing to inadequate mobilization, (d) rectal devascularization caused by rectal wall damage, (e) an error in diagnosis because of lack of a distal colostogram, (f) incomplete separation of the rectum from the genitourinary tract, (g) failed attempts to repair a cloaca with a common channel longer than 3 cm, or those with a very high rectum. CONCLUSIONS The complications we observed usually had a clear explanation. They can be considered preventable as adherence to specific principles in technique avoids them. Key technical maneuvers are discussed to prevent these complications.

Abstract
PURPOSE Surgical repair of rectovaginal fistula with an advancement flap has had suboptimal results. The existing literature documenting episioproctotomy as a surgical option in females with rectovaginal fistula or cloaca is limited. This study was designed to examine our experience with episioproctotomy in this group. Additionally we were interested in risk factors, which might predict failure. METHODS All females who had repair of a rectovaginal fistula or cloaca with episioproctotomy from 1998 to 2004 were studied. Data were collected from chart review and telephone contact. This included demographics, body mass index, tobacco use, Crohn's disease, previous surgery, and diverting stoma. RESULTS Data were obtained from 42 females (mean age, 39.2 (range, 25-70) years). The mean follow-up was 37 (range, 2-84) months. Nine females had a cloaca and the rest had a rectovaginal fistula with an anterior sphincter defect. Eleven (all with anterior tissue) had recurrence of fistula. None with cloaca had recurrence. Eight of 11 recurrences occurred in females who had failed at least one previous repair. No variables that were studied significantly affected recurrence. Median (25th, 75th percentiles) postoperative Wexner incontinence scores for those with and without recurrence were 8 (7, 12) and 5 (2, 6) respectively. CONCLUSIONS Episioproctotomy is a successful technique for repair of rectovaginal fistula and cloaca. Incontinence score postoperatively were acceptable. It should be considered a first line of surgical treatment in those with a fistula that includes compromise of the anterior sphincter complex.

Abstract
We reviewed retrospectively 45 patients (46 procedures) with bladder exstrophy treated by bilateral oblique pelvic osteotomy in conjunction with genitourinary repair. The operative technique and post-operative management with or without external fixation are described. A total of 21 patients attended a special follow-up clinic and 24 were interviewed by telephone. The mean follow-up time was 57 months (24 to 108). Of the 45 patients, 42 reported no pain or functional disability, although six had a waddling gait and two had marked external rotation of the hip. Complications included three cases of infection and loosening of the external fixator requiring early removal with no deleterious effect. Mid-line closure failed in one neonate managed in plaster. This patient underwent a successful revision procedure several months later using repeat osteotomies and external fixation. The percentage pubic approximation was measured on anteroposterior radiographs pre-operatively, post-operatively and at final follow-up. The mean approximation was 37% (12% to 76%). It varied markedly with age and was better when external fixation was used. The wide range reflects the inability of the anterior segment to develop naturally in spite of close approximation at operation. We conclude that bilateral oblique pelvic osteotomy with or without external fixation is useful in the management of difficult primary closure in bladder exstrophy, failed primary closure and secondary reconstruction.

Abstract
We describe a child with the rare clinical entity of female pseudohermaphroditism, accessory phallic urethra, and posterior cloaca who was successfully treated with posterior sagittal anorectovaginourethroplasty. Masculinization was limited to the external genitalia, and no chromosomal, metabolic, or adrenal abnormalities were detected. Associated pathology included bilateral vesicoureteric reflux, a non functioning dysplastic kidney, and bicornuate uterus. The investigation and surgical management of this particularly challenging combination of anomalies is detailed.

Abstract
OBJECTIVE To review our experience with revision vaginoplasty without using bowel, by the posterior sagittal approach. PATIENTS AND METHODS The notes of eight patients (median age 12.3 years, range 9.0-15.6) were retrospectively reviewed; all had had revision vaginoplasty using a posterior sagittal approach. Their original diagnosis was cloacal anomaly in three, urogenital sinus in two, cloacal exstrophy in two, and congenital adrenal hyperplasia in one patient. RESULTS Indications for re-operation included: haematocolpos in four patients, absent vaginal opening in two, hydrocolpos in one, and vesico-vaginal fistula in one. The vagina was reconstructed by total urogenital mobilization in seven patients and in one by anastomosing anterior and posterior aspects of a duplicated vagina. The vagina was mobilized by up to 6 cm in this manner. Bowel was not required for any of the vaginoplasties. The median (range) inpatient stay was 6 (4-17) days after surgery and the median follow-up was 35.3 (4.5-50) months. One patient developed a vesico-vaginal fistula and vaginal stenosis, and had further surgery. Two patients required subsequent use of vaginal dilators. The remainder have had a satisfactory outcome. CONCLUSIONS For revisional vaginal surgery the posterior approach provides excellent exposure, and can be useful in dealing with a variety of pathologies. Combined with total urogenital mobilization, vaginoplasty can be successful despite long common channels. However, there were still several complications.

Abstract
Fetal female urogenital anomalies are often difficult to evaluate by ultrasonography, especially in late gestation. We report a case of fetal hydrometrocolpos detected at 35 weeks of gestation. Ultrasonography revealed a large retrovesical septate hypoechogenic mass in the fetal abdomen, however the sonographic findings were inconclusive. Magnetic resonance imaging (MRI) confirmed that the abdominal mass was fluid-filled with a mid-plane septum in the midline posterior to the bladder, and showed a connection to the dilated uterus that was duplicated. These findings were consistent with a diagnosis of hydrometrocolpos with septate vagina and uterus didelphys. The neonate showed abdominal distension, ambiguous genitalia and anal atresia with a single perineal opening. Hydrometrocolpos was secondary to a urethral type of cloacal anomaly. Aspiration of the mass and a colostomy were performed on the first postnatal day, followed by anorectoplasty at 19 months of age. MRI is a useful complementary tool for assessing fetal urogenital anomalies when ultrasonography is inconclusive.

Abstract
OBJECTIVE To report the urological outcome of the surgical correction of persistent cloaca, which is technically demanding and may require many procedures in an effort to preserve renal function and provide urinary continence. PATIENTS AND METHODS A retrospective chart review from 1971 to 2003 identified 23 patients with cloacal malformations (two posterior, 21 classical) that were reconstructed. The confluence of the urethra, vagina and rectum was noted to be high in 16, low in five and unknown in two; one patient was a conjoined twin. RESULTS The mean (range) follow-up was 9.3 (0.4-31.6) years. Urinary anomalies included 14 patients with renal anomalies (six solitary kidneys, four renal dysplasia, two pelvi-ureteric junction, one each duplex and crossed fused) and two duplicated bladders. Vesico-ureteric reflux was present in 13 patients (57%), hydronephrosis at birth in 13, a bony vertebral abnormality in 14 and the VACTERL association in four. Total urogenital mobilization (TUM) was used in six patients and spinal cord untethering in four; a nephrectomy was required in three and partial nephrectomy in one. Upper tract dilation was still present in six patients. Age-adjusted creatinine levels were abnormal in four (18%) patients and borderline in another six (26%). In the nine patients with a solitary kidney (six solitary, three after nephrectomy), the age-adjusted creatinine level was abnormal in two and borderline in four. A vesicostomy was initially performed in 11 patients. The method of bladder emptying is known in 22; 10 void, 11 require clean intermittent catheterization (five abdominal stoma, six urethral) and one was diverted with a conduit. Of the 18 patients aged > 47 months 15 were continent (14 complete > 4 h, one partial 2-4 h), and three are wet (one conduit). Reconstruction of the lower urinary tract included four bladder augmentations (one ureteric, one ileal, two colon), five bladder neck procedures (two artificial sphincter, one each bladder neck repair, sling, bladder neck division) and six catheterizable channels (one now with a colon conduit). The ureters were re-implanted in 12 patients. CONCLUSION Although the surgical correction of this rare malformation is complex, the upper urinary and lower urinary tract outcome can be favourable, albeit after several reconstructive procedures. TUM has emerged as the primary method for vaginal reconstruction, but the long-term lower tract outcome after this procedure is awaited.

Abstract
PURPOSE Urinary control after definitive repair of a cloacal anomaly is difficult to achieve. The present report aims to describe the clinical course of urinary control, and the need for the management of bladder dysfunction after reconstruction. METHODS The present consecutive series consisted of 11 girls who underwent definitive repair of cloacal anomalies over a period of 11 years. Eight patients were associated with hydrocolpos. Radiological examination included a plain X-ray radiograph of the lumbosacral spine and a voiding cystourethrography with or without a urodynamic study. RESULTS Reconstruction of the cloaca was performed on patients aged between 1 and 3 years using a posterior sagittal approach. Vaginal reconstruction was carried out 13 times in 11 patients using tubularized vaginal flap, distal rectal segment, perineal skin flap, or total urogenital sinus mobilization. Cystostomy or vesicostomy was carried out in four newborns/infants. Another seven patients could void spontaneously but incompletely with residual urine. Occult spinal dysraphism was found in five patients and hemisacrum in two patients. After definitive reconstruction, most patients acquired an adequate to normal bladder volume for 1-year-olds. Normal detrusor-sphincter function was seen in three patients. Detrusor areflexia was seen in two patients who underwent in utero vesico-amniotic shunt. Detrusor underactivity was observed in six patients. Bladder compliance was good in all patients except for one. No patients in the present series showed persistent urinary incontinence from the bladder neck or urethral dysfunction. CONCLUSION It is postulated that wetting after definitive repair may be the result of overflow incontinence and poor bladder contractility rather than sphincter injury. The main clinical characteristic of bladder dysfunction was a failure to empty. We could not define the exact etiology, but iatrogenic injury from extensive dissection can lead to the higher risks of peripheral nerve damage. Accomplishment of definitive repair involves not only anatomical reconstruction, but also postoperative urinary control, including the initiation of clean intermittent catheterizations under repeated urodynamic evaluations.

Abstract
Clinicians caring for newborns with persistent cloaca face significant challenges in the newborn period. Avoiding key pitfalls during this time can have dramatic implications. We reviewed the medical records of 361 patients with cloaca operated on at our institution and analyzed sequelae that resulted from incorrect management in the newborn period. Of 361 patients, 282 underwent primary operations at our institution, and 79 patients were referred to us after a failed repair at other institutions. Pitfalls in management during the newborn period included the following: (1) Failure to recognize and manage hydrocolpos, which occurred in 46 patients. Of these, three patients developed pyocolpos (two progressed to vaginal perforation), and 43 suffered from persistent bilateral hydronephrosis, megaureters, recurrent urinary tract infections, persistent acidosis, or failure to thrive due to undrained hydrocolpos. They underwent unnecessary urinary drainage procedures (nephrostomy, ureterostomy, cystostomy, or vesicostomy) in the newborn period. When the vagina was finally decompressed, all of these symptoms disappeared. (2) Colostomy or vesicostomy problems, which occurred in 50 patients. These included incorrect placement of the colostomy (too distal, which interfered with the pull-through) in 24 and colostomy prolapse in 23. Incompletely diverting loop colostomies led to urinary tract infections in 49 patients. Vesicostomy prolapse occurred in three patients. (3) Clinical misdiagnosis, which occurred in 42 patients. Six were incorrectly diagnosed as "intersex" and 36 as "rectovaginal fistula." In this group only the rectum was repaired, and the patients were left with a urogenital sinus that required reoperation. Proper management of a newborn with cloaca includes drainage of a hydrocolpos, which avoids unnecessary urinary diversions and pyocolpos. Our preferred colostomy is one with separated stomas, adequate distal bowel for the pull-through, and use of a proper technique to avoid prolapse. Correct clinical diagnosis of cloaca avoids problems during the definitive repair.

Abstract
PURPOSE Patients with cloacal anomalies often suffer bladder dysfunction with recurrent urinary infections and incontinence. We examined the effect of surgical reconstruction by posterior sagittal approach and total urogenital mobilization in either causing or worsening bladder dysfunction. MATERIALS AND METHODS Between August 2000 and December 2002 all new patients with cloacal anomalies were prospectively studied to assess the effect of surgical reconstruction by posterior sagittal approach and total urogenital mobilization on bladder function. A comparable group of patients with anorectal malformation (ARM) were studied as comparative controls to assess the effect of posterior sagittal approach without urogenital surgery. Structural anatomy was defined by radiology. Natural filling urodynamics via suprapubic catheter were performed in all infants at 0.2 to 9 months (mean 3) before surgical reconstruction. This assessment was repeated 6 to 24 months (mean 14.8) after surgery, and changes in bladder function were determined by comparative statistics. RESULTS A total of 10 patients with cloacal anomalies (5 with short [less than 3 cm] and 5 with long common channel [greater than 3 cm]) and 20 patients with anorectal malformation were consecutively studied. At presentation bladder dysfunction was present in 9 of 10 patients with cloacal anomalies and in 12 of 20 patients with ARM. After surgery there was significant deterioration in bladder function in half of the cloacal group (5 of 10 patients, p = 0.04) and in 1 of 20 patients with ARM (p = 0.7). Of the 5 patients with cloacal anomalies who had deterioration of bladder function urodynamic pattern of detrusor overactivity changed to inadequate (atonic) bladder in 4, all of whom had a long common channel at presentation. CONCLUSIONS Patients with cloacal malformation have a high incidence of innate bladder dysfunction. However, surgical reconstruction by total urogenital mobilization can cause further deterioration of bladder function, particularly in the group with a long common channel. Urodynamic assessment is necessary to detect bladder dysfunction in these patients.

Abstract
BACKGROUND/PURPOSE The aim of this study was to review the management of the gastrointestinal tract in cloacal exstrophy and to assess the effect of spinal dysraphism on nutritional outcome. METHODS Twenty-two patients with cloacal exstrophy were reviewed retrospectively. Gastrointestinal and spinal anomalies were documented. The need for nutritional supplementation was recorded. Weights at 1 and 5 years of age were used to assess growth in childhood. RESULTS Ten patients were treated initially with ileostomy, 7 with colostomy, and 3 without stoma. Two patients died before surgical reconstruction. Total parenteral nutrition (TPN) was utilized in 8 infants for a median of 10 days (range, 5 to 200). Three patients had complications with colostomies requiring conversion to ileostomy. Patients with an ileostomy required more nutritional supplementation compared with patients with a colostomy (50% v 28%). High-output stoma losses were more common in patients with an ileostomy (40% v 14%). Fourteen patients (67%) with spinal dysraphism had a higher incidence of failure to thrive in the first year of life (69% v 26%) and multiple episodes of enteritis (40% v 25%). Two neonates with duodenal atresia and small bowel deletion died within the first month of life. One patient with short bowel syndrome died of TPN-associated liver disease at 6 months of age. There were no other deaths. CONCLUSIONS The gastrointestinal tract contributes significantly to the morbidity and mortality in cloacal exstrophy. Nutritional supplementation is more frequently required in patients with an ileostomy. Stoma complications were higher in those with a colostomy. Morbidity is high in patients with spinal dysraphism.

Abstract
The cloacal dysgenesis or persistent cloaca is an anomaly included in urogenital tract malformations (UGM) and, in particular, in anomalies due to a missed development of the urogenital septum. The UGM occur during 6-11th weeks of gestation owing to a stop and/or alteration of the normal development and subdivision process of the cloaca, the embryonic structure from which gives origin to the ano-rectal segment of midgut, bladder, ureters, vagina and uterus. The case of a patient submitted to many surgical treatments for urogenital tract congenital malformations is described; when pregnant, she carried other pregnancy until the 34th week of gestation, giving birth a newborn by cesarean section. The patient was checked constantly for her general conditions and, in particular, her renal functions by an active collaboration between internist, nephrologist and gynecologist.

Abstract
BACKGROUND/PURPOSE The aim of this study was to describe lessons learned from the authors' series of patients with cloaca and convey the improved understanding and surgical treatment of the condition's wide spectrum of complexity. METHODS The medical records of 339 patients with cloaca operated on by the authors were retrospectively reviewed. RESULTS A total of 265 patients underwent primary operations, and 74 were secondary. All patients were approached posterior sagittally; 111 of them also required a laparotomy. The average length of the common channel was 4.7 cm for patients that required a laparotomy and 2.3 cm for those that did not. Vaginal reconstruction involved a vaginal pull-through in 196 patients, a vaginal flap in 38, vaginal switch in 30, and vaginal replacement in 75 (36 with rectum, 31 with ileum, and 8 with colon). One hundred twenty-two patients underwent a total urogenital mobilization. Complications included vaginal stricture or atresia in 17, urethral strictures in 6, and urethro-vaginal fistula in 19, all of which occurred before the introduction of the total urogenital mobilization. A total of 54% of all evaluated patients were continent of urine and 24% remain dry with intermittent catheterization through their native urethra and 22% through a Mitrofanoff-type of conduit. Seventy-eight percent of the patients with a common channel longer than 3 cm require intermittent catheterization compared with 28% when their common channel was shorter than 3 cm. Sixty percent of all cases have voluntary bowel movements (28% of them never soiled, and 72% soiled occasionally). Forty percent are fecally incontinent but remain clean when subjected to a bowel management program. Forty-eight patients born at other institutions with hydrocolpos were not treated correctly during the neonatal period. The surgeons failed to drain the dilated vaginas, which interfered with the drainage of the ureters and provoked urinary tract infections, pyocolpos, and/or vaginal perforation. In 24 patients, the colostomy was created too distally, and it interfered with the pull-through. Twenty-three patients suffered from colostomy prolapse. All of these patients required a colostomy, revision before the main repair. Thirty-six patients underwent reoperation because they had a persistent urogenital sinus after an operation done at another institution, and 38 patients underwent reoperation because they suffered from atresia or stenosis of the vagina or urethra. The series was divided into 2 distinct groups of patients: group A were those with a common channel shorter than 3 cm (62%) and group B had a common channel longer than 3 cm (38%). CONCLUSIONS The separation of these groups has important therapeutic and prognostic implications. Group A patients can be repaired posterior sagittally with a reproducible, relatively short operation. Because they represent the majority of patients, we believe that most well-trained pediatric surgeons can repair these type of malformations, and the prognosis is good. Group B patients (those with a common channel longer than 3 cm), usually require a laparotomy and have a much higher incidence of associated urologic problems. The surgeons who repair these malformations require special training in urology, and the operations are prolonged, technically demanding, and the functional results are not as good as in group A. It is extremely important to establish an accurate neonatal diagnosis, drain the hydrocolpos when present, and create an adequate, totally diverting colostomy, leaving enough distal colon available for the pull-through and fixing the colon to avoid prolapse. A correct diagnosis will allow the surgeon to repair the entire defect and avoid a persistent urogenital sinus. Cloacas comprise a spectrum of defects requiring a complex array of surgical decisions. The length of the common channel is an important determinant of the potential for urinary control, and predicts the extent of surgical repair.

Abstract
PURPOSE The aim of this study was to describe laparoscopically assisted anorectovaginoplasty (LAARVP) for the repair of selected types of female anorectal malformation. METHODS Five cases (case 1, rectovaginal fistula with a high rectum; case 2, rectovestibular fistula with double vagina; case 3, rectovestibular fistula with absent vagina; case 4, anovestibular fistula with absent vagina; case 5, cloaca) were reviewed. RESULTS Patient 4 had undergone a posterior sagittal anorectoplasty without vaginoplasty at another hospital after misdiagnosis of simple anovestibular fistula. Mean age at LAARVP was 15.4 months. At LAARVP, the fistula was divided in cases 1 through 4 and dissected as low as possible in case 5. In cases 3 and 4, the distal fistula was used to create the neovagina. In cases 1 through 3, the proximal rectum was mobilized and brought through the pelvic floor sphincter muscles using Georgeson's laparoscopically assisted colon pull-through technique through a minimal perineal incision. A posterior sagittal incision was required in cases 4 and 5. However, the initial laparoscopic approach was very helpful in both cases. Currently, all patients are well after a mean follow-up period of 32.2 months. Mean current age is 4.0 years. Patients 1 through 3 are continent, patient 4 is incontinent with soiling, and patient 5 is too young to be evaluated. CONCLUSIONS LAARVP helps to achieve low dissection of the fistula, gives optimal view of the pelvic organs, provides accurate placement of the anorectal pull-through, and minimizes abdominal perineal scars.

Abstract
We report the anesthetic management for a radical operation in an infant with cloacal exstrophy. Diagnosis of cloacal exstrophy with meningocele was made at the 26th week of gestation. Cesarian section was performed under general anesthesia in order to keep the infant in a state of apnea to prevent aerophagia, the so-called "sleeping baby", at the 38th week of gestation. As soon as the infant was born, she was intubated orotracheally and a radical operation (abdominal closure, removal of meningocele, and vesico-intestinal-pelvioplasty) was performed. Some complications occurred during the operation including hypotension, oliguria, hypothermia, hypoproteinemia, hyponatremia and hyperpotassemia. The operation time was 10 hours and 30 minutes. Mechanical ventilation was continued for 4 days in the NICU and the infant was discharged 37 days after the operation. Early prenatal diagnosis and simulation of the operation enabled an effective surgical procedure allowing us to minimize these intraoperative complications.

Abstract
PURPOSE Neurovesical dysfunction (NVD) is common in children with anorectal malformation (ARM). NVD is mainly related to tethered cord or iatrogenic injury but how to investigate it is still debated. We evaluate the usefulness of routine magnetic resonance imaging (MRI) and urodynamics (UDS) for ARM. MATERIALS AND METHODS A total of 89 children were screened for sacral, spinal or urological anomalies using sacrum x-ray, MRI, renal and spinal ultrasound, uroflowmetry and/or 4-hour voiding observation. UDS was performed in 60 patients with suspected NVD. Mean +/- SD followup was 9.8 +/- 5.2 years. RESULTS Of the 89 patients 29 presented with urinary tract anomalies. The prevalence of sacral (53 cases) and spinal cord (54) anomalies was no different between patients with low, intermediate and high ARM. Spinal cord tethering was present in 13 patients with a normal sacrum x-ray. NVD was found in 31 of the 89 patients (hyperreflexia 21 and hypo-areflexia 10), and was associated with sacral and spinal anomalies in 23, occult spinal dysraphism without bone lesion in 3 and sacral anomalies in 5. The incidence of NVD was 40% of cases with low and 51% with high ARM. CONCLUSIONS Because tethered cord occurs in children without sacral anomalies as well as in those with low ARM, we recommend evaluation of all patients using MRI. When MRI is positive UDS should be performed. We agree with a previous suggestion to evaluate all males with rectourethral fistula and females with cloaca malformations. Finally we recommend a noninvasive evaluation for all other children and UDS when neurogenic dysfunction is suspected.
