    在第三世界国家受极端主义影响的地区,一名初生者生下了一名新生儿,他通过该州首府的视频轮进行了远程咨询。不幸的是,这些异常经常被忽视和得不到治疗.这个婴儿有多处肢体缺陷,腹裂,膀胱外翻和脊柱裂。可悲的是,由于该地区缺乏临床和外科专业知识,新生儿无法生存。强调在服务不足的地区为孕妇建立电子诊所的重要性至关重要,为他们提供高质量的异常扫描。
    A primigravida in the extremist-affected region of a third-world nation gave birth to a newborn who was remotely consulted through video rounds from the capital of the state. Unfortunately, these abnormalities are often overlooked and left untreated. The baby had multiple limb defects, gastroschisis, exstrophy of the bladder and spina bifida. Tragically, the newborn did not survive due to the lack of clinical and surgical expertise in the area. It is crucial to emphasise the importance of establishing e-clinics for expectant mothers in underserved areas, providing them with access to high-quality anomaly scans.

    目的:回答在经典膀胱外翻中使用不完全的阴茎拆卸是否有可能实现尿道闭合的完全覆盖的问题。我们假设在巴克筋膜下动员了身体,他们通过Buck筋膜切口的背侧移位和在尿道上方缝合身体凸侧将允许尿道的身体覆盖延伸,降低尿道-皮肤瘘形成的风险。
    方法:对所有接受改良的Cantwell-Ransley原发性阴茎重建的男孩进行了前瞻性随访。纳入标准包括我们机构的膀胱外翻关闭,确保术后随访期不少于24个月。该技术的关键创新在于对巴克筋膜下的依赖语料库的深度解剖,然后通过Buck筋膜的背侧切口进行背侧重新定位,和有限的外部身体旋转90度只在阴茎的底部。
    结果:在2019年11月至2022年3月之间,18名11至35个月的男孩符合纳入标准,并接受了改良的阴茎重建。外科手术和术后期间不包括任何主要并发症。在18例患者中,有15例实现了尿道缝线的完全覆盖。随访2年内未观察到尿道-皮肤瘘。所有个体都表现出自发勃起,并记录了背侧弯曲的缺失。
    结论:改良的阴茎不完全拆卸技术应用于同质的经典膀胱外翻患者组,允许阴茎轴伸长,改善美学效果,保存的勃起,并消除背侧弯曲。该技术证明了可行性和可靠性,同时保持了对组织循环的积极影响。尿道皮肤瘘的缺失归因于尿道缝线的完全覆盖,并支持最初的假设。
    OBJECTIVE: To answer the question of whether it is possible to achieve complete corporal covering of the urethral closure using incomplete penile disassembly in classic bladder exstrophy. We hypothesize that mobilization of the corpora under Buck\'s fascia, their dorsal translocation through the incisions in Buck\'s fascia and suturing corporal convex sides above the urethra would allow extend corporal covering of the urethra, reducing the risk of urethra-cutaneous fistula formation.
    METHODS: A prospective follow-up on all boys who underwent the modified Cantwell-Ransley primary penile reconstruction was conducted. Inclusion criteria comprised bladder exstrophy closure in our institution, ensuring a postoperative follow-up period of no less than 24 months. The key innovation of the technique lies in a deep dissection of the dependent corpora under Buck\'s fascia, followed by their dorsal relocation through extended dorsal incisions in Buck\'s fascia, and limited external corporal rotation 90 degrees only at the base of the penis.
    RESULTS: Between November 2019 and March 2022, 18 boys aged 11 to 35 months met the inclusion criteria and underwent the modified penile reconstruction. Surgical procedures and postoperative period did not include any major complications. Total corporal covering of the urethral sutures was achieved in 15 of 18 patients. No urethra-cutaneous fistulas were observed within 2 years of follow-up. All individuals demonstrated spontaneous erections, and the absence of dorsal curvature was documented.
    CONCLUSIONS: The modified technique of incomplete penile disassembly applied in a homogenous group of patients with classic bladder exstrophy allows penile shaft elongation, improved aesthetic outcomes, preserved erections, and eliminates dorsal curvature. The technique demonstrated feasibility and reliability while maintaining positive effects on tissue circulation. The absence of urethra-cutaneous fistulae is attributed to the complete corporal covering of the urethral sutures and supports the initial hypothesis.

    膀胱外翻-外翻综合征包括儿科泌尿科医师治疗的一些最具挑战性的疾病。它们与需要多个复杂的重建程序有关,旨在恢复膀胱的解剖结构和功能,尿道和外生殖器。这些患者经常忍受多次重做重建手术以改善泌尿功能,在生命的头二十年里,性功能和美容。在这篇文章中,我们介绍了30年的经验,一个单一的外科医生进行重做手术的男性出生与膀胱外翻。通过对6例临床病例的详细记录,我们强调了可能有助于这些患者成功手术重建的技术方面.本文专门针对接受或不伴有节制手术的重做尿道下裂修复的患者。我们为通过体部的外部旋转来完全拆卸阴茎以纠正复发性背侧弯曲提供了理由;这种方法还可以使外科医生在打开结间疤痕/带后进入近端尿道和膀胱颈。当膀胱上的额外程序时,这是有用的,比如膀胱颈剪裁,是必要的。我们还强调了在进行皮肤闭合时避免反向Byars\'皮瓣的重要性,由于产生的中线疤痕。除了与不良的美容结果有关,它也可以有助于复发性背弯曲。作者主张旋转皮瓣覆盖阴茎轴。通过完全拆卸阴茎而获得的背部弯曲的矫正和改善的美容效果有时是以尿道下裂留下尿道为代价的(图)。这将需要进一步的手术(通常是2阶段颊粘膜移植),就像治疗近端尿道下裂一样.在男性中进行重做上腹部手术仍然是一个挑战。病例场景提供的系统方法可能有助于指导外科医生处理这种困难的情况。经典膀胱外翻修复术后并发症的患者。A)完成阴茎拆卸后,从尿道后部取出石头。B)打开后,膀胱已被打开,膀胱颈部已定制。C)完整的阴茎拆卸已经完成,身体和尿道个性化。D,E,F)修复的最终外观;腹壁用前直肌鞘瓣闭合,阴茎皮肤用旋转皮瓣闭合,尿道最终成为尿道下裂。
    The bladder exstrophy-epispadias complex includes some of the most challenging conditions treated by pediatric urologists. They are associated with the need for multiple intricate reconstructive procedures, aimed at restoring the anatomy and function of the bladder, urethra and external genitalia. These patients often endure multiple redo reconstructive procedures to improve urinary function, sexual function and cosmesis throughout the first two decades of life. In this article, we present the 30-year experience of a single surgeon performing redo surgery for males born with epispadias and bladder exstrophy. Through detailed documentation of 6 clinical cases, we highlight technical aspects that may contribute to a successful surgical reconstruction in these patients. The article is focused specifically on patients undergoing redo epispadias repair with or without concomitant continence procedures. We make the case for complete penile disassembly with external rotation of the corpora to correct recurrent dorsal curvature; this approach also allows the surgeon to have access to the proximal urethra and bladder neck after opening the intersymphiseal scar/band. This is useful when additional procedures on the bladder, such as bladder neck tailoring, are necessary. We also highlight the importance of avoiding reverse Byars\' flaps when performing skin closure, due to the resulting midline scar. Besides being associated with a poor cosmetic outcome, it can also contribute to recurrent dorsal curvature. The authors advocate for rotational skin flaps to cover the penile shaft. Correction of dorsal curvature and improved cosmesis obtained with complete penile disassembly sometimes comes at the expense of the urethra being left as a hypospadias (figure). This will require further surgeries (usually a 2-stage buccal mucosa graft), much like the treatment of proximal hypospadias. Redo epispadias surgery in males remains a challenge. The systematic approach offered by the case scenarios may help guide surgeons dealing with this difficult condition. Patient with complications after repair of classic bladder exstrophy. A) Stone retrieved from posterior urethra after complete penile disassembly. B) After opening the inter-symphiseal scar, the bladder has been opened and the bladder neck tailored. C) Complete penile disassembly has been completed with corporal bodies and urethra individualized. D,E,F) Final appearance of the repair; abdominal wall was closed with anterior rectus sheath flaps, penile skin was closed with rotational flaps and urethra ended up as a hypospadias.

    背景:耻骨舒张的评估对于膀胱外翻-外翻综合征患者的手术计划很重要。了解手术随访期间的舒张变化可能有助于预测患者的发病率。放射照相术可以随访,但可能会受到患者和技术成像因素的影响,包括体型,成像协议,和设备。使用成像校准和解剖比可以减轻由于这些方面的差异。
    目的:使用成像体模来评估射线照相校准对儿童生长时耻骨舒张和内部解剖比例测量的影响。
    方法:获得了三种不同大小的计算机断层扫描体模(年龄较大的儿童,孩子,和婴儿)使用三种成像技术,包括儿童的骨骨盆。用腹部和骨盆技术对所有体模进行成像。还使用胸腹技术对婴儿体模进行了成像。这些暴露全部用来自三个制造商的系统重复。线性测量是在为模拟耻骨舒张和骶骨宽度而放置的射线照相标记之间进行的。还在这些距离之间创建了比率。两名儿科放射科医生使用在图像采集时放置的标尺进行有和没有图像校准的测量。
    结果:对测量结果进行了极好的评估者之间的协议,ICC>0.99。前距离比后距受放大倍数的影响更大,未校准的前距离与校准的前距离之间存在显着差异(p=0.04),而后距离则没有差异(p=0.65)。没有校准或校准的射线照相设备制造商之间没有差异(p值0.66至0.99)。胸腹和腹部(p=0.04)以及骨盆(p=0.04)技术之间的模拟耻骨距离存在显着差异,每个p=0.6。在有或没有校准的情况下,模拟的耻骨舒张与骶骨宽度之间的比率因体模大小(所有p<0.01)和成像技术(p值0.01至0.03)而异。然而,数值差异可能没有临床意义.
    结论:图像校准导致更均匀的测量结果,比未校准的患者更准确,成像技术,和设备。图像校准对于在所有投影成像上精确测量耻骨间距是必要的。盆腔比例的微小差异可能没有临床意义,但是在有更好的理解之前,图像校准可能是谨慎的。
    BACKGROUND: The assessment of pubic diastasis is important for the surgical planning of patients with bladder exstrophy-epispadias complex. Understanding how the diastasis changes during surgical follow-up may help predict patient morbidity. Radiography can follow diastasis but may be affected by patient and technical imaging factors including body size, imaging protocol, and equipment. Using imaging calibration and anatomic ratios may mitigate differences due to these aspects.
    OBJECTIVE: Use imaging phantoms to assess the effect of radiographic calibration on measurements of pubic diastasis and an internal anatomic ratio as a child grows.
    METHODS: Radiographic images were obtained of three different sizes of computed tomography phantoms (older child, child, and infant) using three imaging techniques that include the osseous pelvis in children. All phantoms were imaged with abdomen and pelvis techniques. The infant phantom was additionally imaged using a thoracoabdominal technique. These exposures were all repeated with systems from three manufacturers. Linear measurements were made between radiographic markers placed to simulate pubic diastasis and sacral width. A ratio was also created between these distances. Measurements with and without image calibration were made by two pediatric radiologists using rulers placed at the time of image acquisition.
    RESULTS: There was excellent interrater agreement for measurements, ICC >0.99. Anterior distances were more affected by magnification than posterior ones with a significant difference between uncalibrated versus calibrated anterior distances (p=0.04) and not for posterior ones (p=0.65). There was no difference between radiographic equipment manufacturers without or with calibration (p values 0.66 to 0.99). There was a significant difference in simulated pubic distance between thoracoabdominal and abdomen (p=0.04) as well as pelvic (p=0.04) techniques which resolved with calibration, each p=0.6. The ratio between the simulated pubic diastasis and sacral width differed by phantom size (all p<0.01) and imaging technique (p values 0.01 to 0.03) with or without calibration. However, the numerical differences may not be clinically significant.
    CONCLUSIONS: Image calibration results in more uniform measurements that are more accurate than uncalibrated ones across patient size, imaging techniques, and equipment. Image calibration is necessary for accurate measurement of inter-pubic distances on all projection imaging. Small differences in the pelvic ratio likely are not clinically significant, but until there is a better understanding, image calibration may be prudent.

    该病例报告描述了成功使用附着在股血管上的背阔肌皮瓣来掩盖一名27岁女性膀胱外翻的大量质量损失。手术后六个月,两阶段重建显示出出色的效果。
    方法:一名27岁女性膀胱外翻,既往行Mitrofanoff型尿路改道合并晚期筋膜瓣,10年后在耻骨联合附近出现管裂。使用背阔肌皮瓣和聚丙烯网进行了两阶段重建,具有出色的美学和功能效果。
    背阔肌皮瓣,J.M.Servant在1984年将其描述为“苹果营业额”技术,对于重建大量物质损失,具有最小的功能后遗症非常可靠。在这种情况下,手术在术后六个月获得了非常令人满意的美学和功能结果。这种方法提供了一种安全有效的最后手段。
    结论:两阶段背阔肌皮瓣技术是一种可靠的,安全有效地解决了这一复杂的重建挑战。
    UNASSIGNED: This case report describes the successful use of a latissimus dorsi muscle flap attached to the femoral vessels to cover a large mass loss in a 27-year-old woman with bladder exstrophy. The two-stage reconstruction showed excellent results six months after surgery.
    METHODS: A 27-year-old woman with bladder exstrophy and previous enterocystoplasty with Mitrofanoff-type urinary diversion combined with a late fascial flap presented 10 years later with disembowelment near the pubic symphysis. A two-stage reconstruction using a latissimus dorsi flap and polypropylene mesh was performed with excellent aesthetic and functional results.
    UNASSIGNED: The latissimus dorsi muscle flap, described by J.M. Servant in 1984 as the \"apple turnover\" technique, is highly reliable for reconstructing large substance losses with minimal functional sequelae. The procedure in this case resulted in very satisfactory aesthetic and functional results at six months postoperatively. This approach provided a safe and effective technique of last resort.
    CONCLUSIONS: the two-stage latissimus dorsi flap technique was a reliable, safe and effective solution for this complex reconstructive challenge.

    膀胱外翻外翻综合征(BEEC)是一种病因不明的罕见先天性异常,虽然,遗传和环境因素与它的发展有关。据报道,在泌尿生殖途径中表达的几种基因的变体是人类和小鼠模型中膀胱外翻的原因。下一代测序和分子基因组学的扩展提高了我们识别类似复杂疾病的潜在遗传原因的能力,因此可以帮助研究BEEC的分子基础。
    目的是确定先前与膀胱外翻有关的基因中罕见杂合变体的存在,并将它们与我们研究人群中膀胱再生的存在或不存在相关联。
    我们介绍了12例BEEC患者的病例系列,这些患者在膀胱颈重建术或膀胱扩大术期间由儿科泌尿科进行了膀胱活检。根据膀胱体积大于或小于预期膀胱大小的40%,将病例分类为“足够”或“不足”(分别为5和7)。对照膀胱组织标本是从接受活检的患者(n=6)获得的,这些患者的情况不是膀胱外翻。对从膀胱标本分离的DNA进行全外显子组测序。基于从头突变的假设,以及具有不完全外显率的常染色体显性条件的潜在含义,对每例病例进行了常染色体显性变异的评估,这些变异的一组基因先前与BEEC有关.
    我们对文献的回顾确定了44个与人类膀胱外翻模型有关的基因。我们的整个外显子组测序数据分析在分类为足够的病例中确定了其中两个基因的罕见变异,在被归类为不足的病例中,其中五个基因中的七个变异。
    我们在我们的BEEC标本中发现了七个先前涉及的基因中的罕见变异。需要进一步的研究来进一步了解这种潜在的遗传异质性胚胎条件的细胞信号传导。
    UNASSIGNED: Bladder exstrophy epispadias complex (BEEC) is a rare congenital anomaly of unknown etiology, although, genetic and environmental factors have been associated with its development. Variants in several genes expressed in the urogenital pathway have been reported as causative for bladder exstrophy in human and murine models. The expansion of next-generation sequencing and molecular genomics has improved our ability to identify the underlying genetic causes of similarly complex diseases and could thus assist with the investigation of the molecular basis of BEEC.
    UNASSIGNED: The objective was to identify the presence of rare heterozygous variants in genes previously implicated in bladder exstrophy and correlate them with the presence or absence of bladder regeneration in our study population.
    UNASSIGNED: We present a case series of 12 patients with BEEC who had bladder biopsies performed by pediatric urology during bladder neck reconstruction or bladder augmentation. Cases were classified as \"sufficient\" or \"insufficient\" (n = 5 and 7, respectively) based on a bladder volume of greater than or less than 40% of expected bladder size. Control bladder tissue specimens were obtained from patients (n = 6) undergoing biopsies for conditions other than bladder exstrophy. Whole exome sequencing was performed on DNA isolated from the bladder specimens. Based on the hypothesis of de novo mutations, as well as the potential implications of autosomal dominant conditions with incomplete penetrance, each case was evaluated for autosomal dominant variants in a set of genes previously implicated in BEEC.
    UNASSIGNED: Our review of the literature identified 44 genes that have been implicated in human models of bladder exstrophy. Our whole exome sequencing data analysis identified rare variants in two of these genes among the cases classified as sufficient, and seven variants in five of these genes among the cases classified as insufficient.
    UNASSIGNED: We identified rare variants in seven previously implicated genes in our BEEC specimens. Additional research is needed to further understand the cellular signaling underlying this potentially genetically heterogeneous embryological condition.

    背景:在出生时患有膀胱外翻-外翻综合征(BEEC)的儿童中,实现尿失禁是一个关键目标。不幸的是,尽管有时进行了广泛的手术治疗,但这一目标只能适度实现.因此,反复住院和手术可能会对生活质量产生负面影响。因此,我们认为,在BEEC患者失禁治疗的早期阶段,应探索保守治疗方案。作为其中的一部分,为BEEC重建手术后持续性尿失禁的患者提供了基于的强化尿路治疗方案.
    目的:本研究的目的是评估强化尿路治疗对BEEC患儿术后尿失禁的益处。
    方法:进行了一项回顾性图表研究,包括所有因BEEC重建手术后持续性尿失禁而纳入强化尿路治疗计划的儿童。尿路疗法包括基于认知行为疗法的为期十天的住院培训计划,有经验的泌尿外科医师的密集随访。主要结果测量是失禁,表示为治疗后实现完全失禁(良好结果;100%干燥)或每周湿天数减少50-99%(改善结果)的儿童百分比。
    结果:分析了33例平均年龄为10.6岁的患者的数据。在61%的病例(20/33)中,据报道尿路治疗后尿失禁的改善或良好结果。患有经典膀胱外翻的儿童更常获得良好或改善的结果(13/16;81%),与外裂患儿相比(6/16;38%)。唯一患有泄殖腔外翻的患者完成了治疗,结果有所改善。从患有持续性尿失禁的患者组中,75%(12/16)报告说,在随访结束时,投诉在社会上是可以接受的。
    结论:通过遵循我们的强化尿路治疗计划,大多数患者实现了完全失禁或改善了失禁。此外,我们的研究结果表明,住院培训计划对持续性尿失禁患者的接受度有积极影响。泌尿科治疗师提供个性化的护理和明确的指导,我们认为成功治疗的基本要素。考虑到重复手术可能会阻碍进展,并且不能保证节制,我们建议优先考虑保守治疗方案.
    结论:我们的结果表明,37%(12/33)的BEEC患者因重建手术后持续性尿失禁而参加了我们的强化尿路治疗计划,尿路治疗后达到完全尿失禁,63%(21/33)仍有一定程度的尿失禁。75%的患者没有达到完全的尿失禁,将剩余的失禁描述为社会可接受的。这些发现强烈支持咨询BEEC患者在选择进一步手术之前考虑保守治疗。
    BACKGROUND: Achieving urinary continence is a key goal in children born with the bladder exstrophy-epispadias complex (BEEC). Unfortunately, this goal is only moderately achieved despite sometimes extensive surgical treatment. Undergoing repeated hospitalization and operations may consequently have a negative impact on quality of life. We therefore believe that other, conservative treatment options should be explored in an earlier stage of incontinence treatment in BEEC patients. As part of this, an intensive urotherapy program based on was offered to patients with persistent incontinence after reconstructive surgery for BEEC.
    OBJECTIVE: The aim of this study is to evaluate the benefits of intensive urotherapy on incontinence after reconstructive surgery in children with BEEC.
    METHODS: A retrospective chart study was performed including all children who were enrolled in an intensive urotherapy program because of persistent incontinence after reconstructive surgery for BEEC. Urotherapy consisted of a ten-day inpatient training program based on cognitive behavioral therapy, with intensive follow-up by experienced urotherapists. Main outcome measurement was continence, expressed as the percentage of children that achieved complete continence (good result; 100% dry) or 50-99% decrease of wet days a week (improved result) after treatment.
    RESULTS: Data of 33 patients with a mean age of 10.6 years were analyzed. In 61% of cases (20/33) an improved or good result was reported on incontinence after urotherapy. Children with classic bladder exstrophy more often achieved a good or improved result (13/16; 81%), compared to children with epispadias (6/16; 38%). The only patient with a cloacal exstrophy completed treatment with an improved result. From the group of patients with persistent incontinence, 75% (12/16) reported that the complaints were socially acceptable at the end of follow-up.
    CONCLUSIONS: By following our intensive urotherapy program the majority of patients achieved complete continence or improved incontinence. In addition, our results show that the inpatient training program has a positive impact on acceptance in cases of persistent incontinence. The urotherapists offer individualized care and clear guidance, which we deem essential elements of successful treatment. Considering that repeated surgery may impede progress and offers no guarantee of continence, we recommend giving preference to conservative treatment options.
    CONCLUSIONS: Our results show that 37% (12/33) of patients with BEEC who were enrolled in our intensive urotherapy program because of persistent incontinence after reconstructive surgery, achieved complete continence after urotherapy and 63% (21/33) still experienced some degree of incontinence. 75% of patients who did not achieve complete continence, described the remaining incontinence as socially acceptable. These findings strongly support counselling patients with BEEC to consider conservative treatment before opting for further surgery.
