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
INTRODUCTION Cloacal dysgenesis occurs from failure of embryological division of urogenital sinus and hindgut, leading to a single common perineal opening for genitourinary and gastrointestinal tracts. The prenatal diagnosis of cloacal malformation is imprecise, but the clinical correlation of postnatal findings to prenatal history can help reveal explanations for unusual pathological findings in patients with urogenital abnormalities. CASE PRESENTATION A 21-year-old woman was referred after her 20-week ultrasound demonstrated anhydramnios and concern for dilated fetal bowel. Fetal MRI confirmed anhydramnios and a dilated fetal colon, in addition to hydronephrosis and a pelvic cyst. Repeat ultrasound at 27 weeks showed unexpected complete resolution of her anhydramnios but new fetal ascites. The newborn girl was postnatally diagnosed with a cloacal malformation and an unusual near-complete fusion of her labia. She underwent proximal sigmoid colostomy and a tube vaginostomy at birth followed by cloacal reconstruction at 1.5 years old. CONCLUSION In female fetus with a pelvic cyst, one should have a high index of suspicion for cloacal anomaly and consider the possibility of urinary obstruction leading to alteration in amniotic fluid.

Abstract
Anorectal and cloacal malformations are a broad mix of congenital abnormalities related to the distal rectum and anus. Confusion exists between all the forms in this large and heterogeneous group. The spectrum includes everything from anal stenosis, ventral anus, anal atresia (with and without fistula) and the full spectrum of cloacal malformations. Imaging in these conditions is done through the whole armamentarium of radiologic modalities, with very different imaging strategies seen across the centres where these conditions are managed. In 2017, the European Society of Paediatric Radiology (ESPR) abdominal imaging task force issued recommendations on the imaging algorithm and standards for imaging anorectal malformations. This was followed by further letters and clarifications together with an active multispecialty session on the different imaging modalities for anorectal malformations at the 2018 ESPR meeting in Berlin. Through this paper, the abdominal task force updates its guidelines and recommended imaging algorithm for anorectal malformations.

Abstract
Cloacal malformations are among the most complex types of anorectal malformation and are characterized by the urological, genital, and intestinal tracts opening through a single common channel in the perineum. Long-term outcome is affected by multiple factors, which include anatomical variants of the malformation itself, associated anomalies, and the surgical approach. Reconsidering these variables and their influence on "patient important" function might lead to strategies that are more outcome-driven than focused on the creation of normal anatomy. Key outcomes reflect function in each of the involved tracts and the follow-up needed should therefore not only include the classical fields of colorectal surgery and urology but also focus on items such as gynecology, sexuality, family-building, and quality of life as well as other psychological aspects. Involving patients and families in determining optimal treatment strategies and outcome measures could lead to improved outcomes for the individual patient. A strategy to support delivery of personalized care for patients with cloacal malformations by aiming to define the best functional outcomes achievable for any individual, then select the treatment pathway most likely deliver that, with the minimum morbidity and cost, would be attractive. Combining the current therapies with ongoing technological advances such as tissue expansion might be a way to achieve this.

Abstract
Objective: To document our experience of initial management of Cloacal malformation in female patients. Methods: A descriptive retrospective study was conducted in the Department of Pediatric Surgery of the National Institute of Child Health Karachi from January 2010 to September 2018. Female patients with diagnosis of Cloacal malformation were included in this study. Data regarding the age at presentation, mode of presentation, clinical features, presence of hydrocolpos, and associated anomalies were noted. Surgical procedures performed in these patients and the outcomes were also documented. Data was analyzed on SPSS Version 20. Results: Sixty females were included in the study. Age ranged from birth to three years with a median of four days. Patients admitted through emergency were 44 (73.33%) while 16 (26.66%) were admitted through outpatient clinic. Hydrocolpos was found in 15 (25.00%) patients. Five (8.33%) patients had massive abdominal distention and were presented with severe respiratory distress. Among them three had massive hydrocolpos, one patient had pneumoperitoneum secondary to Meckel’s perforation and one patient was having massive colonic dilatation. Hydronephrosis and hydroureter were found in 14 (23.33%) patients, while dilated bladder was found in three (5.00%) patients. After optimization of patients, bowel diversion was done as transverse colostomy in 39 (65.00%) patients, high sigmoid colostomy in 17(28.33%) patients while ileostomy was done in three (5.00%) patients. All patients with hydrocolpos had tube vaginostomy. None of the patients required bladder diversion and urinary tract dilatations were gradually subsided in nine patients in the post-operative period. Associated anomalies were found in 22(36.66%) of cases predominantly of sacral origin. Operative complications were found in 18(30.00%) patients, including stoma site in infection in 12(20.00%) patients, vaginal tube dislodgement in two patients, wrong placement of tube in one patient and vaginostomy stenosis in one case. While bowel stoma retraction occurred in four patients, prolapsed was found in three patients. Renal failure occurred in one patient. In total, 37(61.00%) patients had smooth recovery, 18(30.00%) patients had some complications, while Five (8.33%) patients were expired due to sepsis. Conclusions: Majority of cloacal malformations present in neonatal life. Initial management is an important step in dealing with these patients. Care must be taken during the abdominal exploration regarding drainage of hydrocolpos and appropriate placement of bowel stoma.

Abstract
INTRODUCTION Precise and accurate measurement of the common channel and urethra is a critical determinant prior to the repair of cloacal malformations. Endoscopy and 3D reconstruction cloacagram are two common modalities utilized to help plan the surgical approach, however the consistency between these methods is unknown. METHODS Common channel and urethral lengths obtained by endoscopy and 3D cloacagram of cloaca patients at six pediatric colorectal centers were compared. Data are given as mean (range). RESULTS 72 patients were included in the study. Common channel measurements determined by 3D cloacagram and endoscopy were equal in 7 cases (10%). Endoscopic measurements of the common channel were longer than 3D cloacagram in 20 (28%) cases and shorter in the remaining 44 (62%) cases. The absolute difference between measurements of the common channel was 7.2 mm (0-2.4 cm). Urethral measurements by both modalities were equal in 8 cases (12%). Endoscopic measurement of the urethra was longer than that by 3D cloacagram in 20 (31%) patients and shorter in 37 (57%) of cases. The absolute difference between measurements of the urethra was 5.1 mm (0-2.0 cm). The reconstruction (e.g. TUM or urogenital separation) that would be performed according to measurements determined by 3D cloacagram and endoscopic measurements differed in 13/62 (21%) patients with each structure identified and common channel measurements of >1 cm. CONCLUSION Significant variation exists in the measurements of the common channel and urethra in patients with cloacal malformations as determined by endoscopy and 3D cloacagram. This variation should be considered as these measurements influence the decision to perform either a TUM or urogenital separation. Based on these findings, 3D cloacagram should be performed in all patients prior to cloaca repair to prevent mischaracterization of the malformation. LEVEL OF EVIDENCE Level IV.

Abstract
BACKGROUND A subset of patients with cloacal malformations requires vaginal replacement during their primary reconstruction, increasing the surgical complexity. Identifying factors which predict the need for vaginal replacement would facilitate operative planning. METHODS We retrospectively reviewed patients who underwent primary cloacal reconstruction at our Center (2014-2018) and assessed the length of the common channel, urethra, and vagina. The presence of hydrocolpos at birth, Müllerian anomalies, sacral ratio, and tethered cord were also assessed between patients who did and did not require vaginal replacement. RESULTS 50 patients were identified. 17/50 patients (34%) underwent a total urogenital mobilization (TUM), and none required vaginal replacement. 33/50 (66%) patients underwent a urogenital separation. 19/33 (58%) required vaginal replacement. This group had a shorter vagina (4.2 cm vs 6.6 cm, p < 0.01). There was no difference in urethral or common channel length, number of cervices, sacral ratio, presence of a vaginal septum, hydrocolpos, or tethered cord between those who did and those who did not require vaginal replacement. CONCLUSIONS Urethral and common channel lengths were used to successfully determine the operative plan (TUM or urogenital separation) to reconstruct cloacal malformations. The need for urogenital separation and a shorter vaginal length were predictive of the need for vaginal replacement. LEVEL OF EVIDENCE Level IV. TYPE OF STUDY Case series with no comparison groups.

Abstract
The term cloacal malformation is commonly used to describe the classic cloacal malformation where there is a single common urogenital and intestinal channel located at the expected site of the urethra. There is, however, a spectrum of cloacal abnormalities that differ from this classic type and are less well discussed in the radiologic and surgical literature. The aim of this pictorial essay is to familiarize radiologists with the anatomy, appropriate terminology and key prenatal imaging findings that differentiate the six entities that constitute the spectrum of cloacal abnormalities.

Abstract
AIM OF THE STUDY Colon vaginoplasty (CV) is often performed for cloacal malformation (CM). We used mice to study the vitality of spermatozoa after contact with colonic mucosa as a factor contributing to infertility. METHODS Spermatozoa isolated from the epididymides of C57BL/6J male mice (n = 23) were syringed directly into the vaginas (Vag-group) or colons (Colo-group) of female mice (n = 45). Vitality was determined by assessing motility using computer-assisted sperm analysis, viability by staining with SYBR-14 and propidium iodide, and fertility by in vitro fertilization, prior to deposition, and at 5, 10, 30, and 60 min after deposition. MAIN RESULTS Motility was significantly decreased in Colo only at 10 and 60 min. Viability of Colo spermatozoa was significant at all assessment times, except at 10 min. Normal fertilization was observed with all Vag spermatozoa, but with Colo, there was arrest of embryo development with spermatozoa collected at 5 and 10 min, and no fertilization with spermatozoa collected at 30 and 60 min. CONCLUSIONS The vitality of spermatozoa is compromised by contact with colonic mucosa which could contribute to infertility in CM after CV, because their ovaries and fallopian tubes are considered to be normal.

Abstract
Persistent cloaca malformation is the most severe type of anorectal and urogenital malformation. Decisions concerning the surgical treatment for this condition are taken during the first hours of life and may determine the quality of life of these patients. Thus, prenatal diagnosis becomes important for a prompt and efficient management of the fetus and newborn, and accurate counseling of the parents regarding its consequences and the future of the baby. Careful evaluation by ultrasonography, and further in-depth analysis with MRI, allow prenatal detection of characteristic findings, which can lead to diagnose or at least suspect this condition. We reviewed our experience and the literature in order to highlight the most important clues that can guide the physician in the differential diagnosis.

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
OBJECTIVE Urinary and faecal continence are key challenges goal of cloacal malformation management. Most well-known prognostic factors are the length of common channel (CC) and the presence of a sacral defect, but the impact of associated spinal dysraphism is less well documented. The aim of this study was to investigate the impact of different types of dysraphism on urinary and faecal continence in this patient population. MATERIALS AND METHODS From 1991 to 2011, charts and office notes of 25 patients with cloacal malformation were retrospectively reviewed. At last clinic visit, urinary and faecal continence status according to Krickenbeck criteria were correlated with the length of CC, the presence of a sacral defect (sacral ratio), and the presence of different types of spinal cord dysraphism using magnetic resonance imaging (MRI) and Fisher's exact test. RESULTS Mean follow-up was 8 years (4 months-21 years). The sacral ratio was abnormal (below 0.74) in 18 cases out of 25 (72%). MRI review showed normal spinal cord in eight out of 23 cases (Group 1), spinal cord anomaly in 15 out of 23 cases (65%) including nine cases of tethered cord complex (Group 2) and six cases of a short spinal cord (Group 3). While statistical analysis showed a difference regarding urinary prognosis between the groups (p=0.005), no significant difference was found regarding faecal prognosis. None of the six patients with short spinal cord were continent for both urinary and faecal prognosis. CONCLUSIONS This is the first study, which highlights the impact of different types of spinal dysraphism on functional outcome in patients with cloaca. Short spinal cord seemed to carry the worst prognosis. A prospective study with a larger series is mandatory to confirm these preliminary results.

Abstract
OBJECTIVE Ultrasound prenatal evaluation of pelvic cystic mass can be challenging. After having ruled out a cloaca anterior to a large hydrocolpos, it is important to differentiate between combined urogenital anomalies such as urogenital sinus and isolated genital anomalies. PATIENTS AND METHODS We reviewed the charts of 13 women referred for a third trimester pelvic MRI for cystic pelvic mass discovered in second trimester ultrasound. We evaluated MRI compared with postnatal surgical findings in order to determine clues for improving prenatal diagnoses. RESULTS MRI excluded the diagnosis of cloacal malformation in nine cases with no false negative. Once a cloaca is ruled out, a different signal between the bladder and the hydrocolpos on T2 sequences is in favor of an isolated genital obstruction. In contrast, in case of urogenital sinus, the vagina is filled with a mixture of genital secretions and urine, which gives it an MRI signal similar to the bladder on T2 sequences. CONCLUSION Third trimester fetal MRI is an essential exam for characterization of pelvic cystic mass diagnosed by ultrasound. This exam appears valuable for invalidating the diagnosis of cloacal malformation and for differentiating between isolated genital obstruction and urogenital sinus.

Abstract
PURPOSE To evaluate the use of small intestinal submucosa (SIS) for bladder augmentation in a series of select patients. MATERIAL AND METHODS Six patients (age 6.5-15.4, mean 9.8 years) underwent bladder augmentation with SIS: one after a cloacal exstrophy repair, one after multiple surgery of the bladder because of vesicoureteral reflux, two with spina bifida, two after bladder exstrophy repair. All suffered from a microbladder with a mean volume of 61.5 ml (range 15-120, 7-36% of expected bladder capacity for age). Preoperative bladder compliance ranged from 1.0 to 3.3 (mean 1.3) ml/cmH2O. RESULTS Follow-up time ranged from 4.6 to 33.5 (mean 24.4) months. An increase of bladder volume was achieved in four patients (53-370 ml, 16-95% of expected bladder capacity for age). Bladder compliance postoperatively ranged from 0.9 to 5.6 (mean 3.0) ml/cmH2O. Histological examinations showed a complete conversion of SIS, leaving irregular urothelial lining and bladder wall containing muscular, vascular and relatively thick connective tissue in four patients and regular urothelium in two patients. Major complications were bladder stones in two patients and a bladder rupture in one patient. CONCLUSION Bladder augmentation with SIS in humans failed to fulfill the hopes raised by animal studies. Due to the insufficient increase in bladder compliance and therefore failure to accomplish sufficient protection of the upper urinary tract, bladder augmentation with SIS cannot be recommended as a substitute for enterocystoplasty.
