Vaginal reconstruction for ambiguous genitalia and congenital absence of the vagina: a 27-year experience

Outcomes of one-stage feminizing genitoplasty in children with congenital adrenal hyperplasia and severe virilization

PURPOSE

To present our surgical experience and outcomes in congenital adrenal hyperplasia (CAH) patients with severe virilization using a combined technique of total urogenital mobilization (TUM) and a modified pull-through vaginoplasty to perform a safe and effective one-stage feminizing genital reconstruction for these children.

METHODS

Fourteen CAH patients with severe virilization, defined by a Prader IV and V rating of the external genitalia, underwent TUM followed by a limited vaginal pull-through procedure from June 2016 to December 2020. Postoperative anatomical and cosmetic outcomes, and urinary continence, were evaluated.

RESULTS

Out of the 14 cases in this study, 8 were classified as prader IV and 6 as Prader V. The median age at surgery was 11 months (range 6-36 months), and the mean urethral length was 1.4 cm (range 1.2-1.8 cm). The median follow-up period was 4 years. Our cosmetic outcomes were good in 11 (78.5%), satisfactory in 2, and poor in one case. All patients achieved age-appropriate toilet training without urinary incontinence.

CONCLUSION

Adopting our surgical approach of TUM with modified pull-through vaginoplasty has simplified feminizing surgical reconstruction in CAH cases with severe genital atypia and a very high vaginal confluence with short urethral length, yielding adequate introitus with good anatomical and cosmetic appearance and adequate urinary continence outcomes.

Bowel vaginoplasty: a systematic review

Among surgical procedures for constructing a neovagina, positive outcomes are reported in literature for bowel vaginoplasty for male-to-female transgenders and patients with vaginal aplasia. This systematic review shows outcomes of bowel vaginoplasty procedures, and rates the quality of evidence of the included studies. A search of the literature was performed in PubMed, Medline, Cochrane Library and SveMed+, in accordance with the PRISMA statement, between January 2016 and February 2018. The PICOS (patients, intervention, comparator, outcomes and study design) approach was used as inclusion criteria. Among 251 analyzed studies only 34 met inclusion criteria. Quality of evidence and methodology were rated according to GRADE and MINORS, respectively. Data from the included studies were extracted based on study characteristics, participants? specifics, type of intervention/treatment and type of outcome measures into data extraction forms. All studies were non-randomized with a high risk of bias and very low quality of evidence according to GRADE. Vaginal reconstruction with isolated bowel segments provides a self-lubricating neovagina with low rates of failure and revision, and without routine dilatation need. Furthermore, the use of laparoscopic techniques offers a better postoperative cosmetic appearance of the abdomen and a shorter hospital stay. Vaginoplasty using bowel segment is a safe and effective procedure that obtains excellent long-term results as reported by the included studies. Despite that further researches are needed improving methodology with larger populations, retrospective qualitative studies and report of outcome measurements using standardized evaluation tools as the Female Sexual Function Index.

Surgical outcomes and complications of reconstructive surgery in the female congenital adrenal hyperplasia patient: What every endocrinologist should know

Surgical management of classical congenital adrenal hyperplasia (CAH) in 46, XX females has evolved significantly. Virilization of the genitalia of 46, XX females with CAH begins prenatally as a result of excess fetal androgen production. Improved understanding of anatomy and surgical outcomes has driven changes in surgical techniques as well as the timing of surgery. For endocrinologists treating these patients, it is important to understand the outcome of genitoplasty, identify patients who need further treatment and direct these patients to experienced surgeons. We performed a literature search on PubMed of publications addressing CAH and genital reconstruction published in the English language from 1990 to the present. In accordance with our institutional review board, we performed a retrospective analysis of clitoroplasty and/or vaginoplasty procedures performed by a single surgeon at our institution from 1996 to 2015. We found that genital reconstruction in 46, XX CAH patients is associated with few immediate post-operative, infectious, and urinary complications. Vaginal stenosis is a common complication of vaginal reconstruction and requires evaluation by an experienced surgeon. Clitoral pain or decreased sensation can be associated with clitoral recession and clitorectomy. Outcomes in sexual satisfaction and gender identity can also be impacted by surgical technique and success. Long term follow up and patient reported feedback are crucial to our understanding and management of this special group of patients. Improved awareness and understanding of the complications of genital surgery will allow endocrinologists to know what to ask patients and be ready to provide them with a resource with the understanding and experience to help them improve their quality of life.

Vaginal agenesis and rectovestibular fistula. Experience utilizing distal ileum for the vaginal replacement in these patients, preserving the natural fecal reservoir

BACKGROUND

The association of rectovestibular fistula (RVF) and vaginal agenesis (VA) presents a diagnostic and management challenge. The vaginal replacement is usually performed with rectum or sigmoid, which are the natural fecal reservoirs; thus, the fecal control could be affected. We present our experience utilizing ileum to preserve the rectum and sigmoid.

METHODS

We performed a retrospective study of eight patients with RVF and VA treated from May 2011 to June 2015 at two colorectal centers, at Pittsburgh and Mexico. We recorded the age at diagnosis of VA, treatment, presence of other associated malformations and outcome.

RESULTS

Eight of forty-nine girls with RVF had an associated VA (16.3%). Three patients had a timely diagnosis and five a delayed diagnosis. Six patients were submitted to a vaginal replacement with ileum and achieved fecal control. Two are waiting for surgery.

CONCLUSIONS

A high index of suspicion of vaginal agenesis helps in a timely diagnosis in girls with RVF. The use of ileum allows for preservation of the fecal reservoirs, thus optimizing the chance for fecal control in patients with anorectal malformations.

Research on quality of life in female patients with congenital adrenal hyperplasia and issues in developing nations

Congenital adrenal hyperplasia (CAH) is the commonest cause of ambiguous genitalia for female newborns and is one of the conditions under the umbrella term of "Disorders of Sex Development" (DSD). Management of these patients require multidisciplinary collaboration and is challenging because there are many aspects of care, such as the most appropriate timing and extent of feminizing surgery required and attention to psychosexual, psychological, and reproductive issues, which still require attention and reconsideration, even in developed nations. In developing nations, however, additional challenges prevail: poverty, lack of education, lack of easily accessible and affordable medical care, traditional beliefs on intersex, religious, and cultural issues, as well as poor community support. There is a paucity of long-term outcome studies on DSD and CAH to inform on best management to achieve optimal outcome. In a survey conducted on 16 patients with CAH and their parents in a Malaysian tertiary center, 31.3% of patients stated poor knowledge of their condition, and 37.5% did not realize that their medications were required for life. This review on the research done on quality of life (QOL) of female patients with CAH aims: to discuss factors affecting QOL of female patients with CAH, especially in the developing population; to summarize the extant literature on the quality of life outcomes of female patients with CAH; and to offer recommendations to improve QOL outcomes in clinical practice and research.

Secondary vaginoplasty for disorders for sexual differentiation: is there a right time? Challenges with compliance and follow-up at a multidisciplinary center

PURPOSE

We present the experience of a multidisciplinary center for disorders of sexual differentiation (DSD) in treating females requiring vaginoplasty. Specifically, we evaluate outcomes and compliance with follow-up protocols in patients undergoing secondary vaginoplasties.

MATERIALS/METHODS

We retrospectively reviewed consecutive DSD patients who underwent feminizing genitoplasties in 2006-2010. A subset of patients were instructed in vaginal self-dilation at time of secondary vaginoplasty. Through follow-up visits and administered questionnaires we assessed outcomes, compliance and overall satisfaction.

RESULTS

Twenty-two feminizing genitoplasties were completed during the study interval. There were no postoperative complications; average blood loss was 74 ml and mean length of stay was 3 days. Ten females underwent secondary vaginoplasty. The response rate to questionnaires was 5 of 9. Age of initiation for self-dilation ranged from 8 to 24 years. Initial compliance two months postoperatively was good, but diminished 12-24 months after surgery. Responses to the quality-of-life questionnaire were diverse, reflecting a range of patient ages and varied experiences.

CONCLUSION

A multidisciplinary, comprehensive approach is necessary to care for patients with DSD due to psychosexual, medical and reconstructive concerns. A secondary vaginoplasty to facilitate menarche and psychosocial concerns is feasible with minimal complications, though compliance and toleration with regard to post-surgical dilation regimens is variable.

Mayer-Rokitansky-Kuster-Hauser syndrome and anal canal stenosis: case report and review of literature

Mayer-Rokitansky-Kuster-Hauser (MRKH) is a characteristic syndrome in which the mullerian structures are absent or rudimentary. It is also associated with anomalies of the genitourinary and skeletal systems. There are very few cases reported regarding its association with anorectal malformations, particularly perineal fistulas. To the best of our knowledge, there have not been any reported cases of anal canal stenosis in patients with MRKH. We describe a very rare association of MRKH with anal canal stenosis and multiple renal calculi. The patient underwent corrective surgery for the anomalies and removal of renal calculi. She has been under regular follow-up for the last few months and is doing well.

Consensus in Guidelines for Evaluation of DSD by the Texas Children's Hospital Multidisciplinary Gender Medicine Team

The Gender Medicine Team (GMT), comprised of members with expertise in endocrinology, ethics, genetics, gynecology, pediatric surgery, psychology, and urology, at Texas Children's Hospital and Baylor College of Medicine formed a task force to formulate a consensus statement on practice guidelines for managing disorders of sexual differentiation (DSD) and for making sex assignments. The GMT task force reviewed published evidence and incorporated findings from clinical experience. Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) was used to assess the quality of evidence presented in the literature for establishing evidence-based guidelines. The task force presents a consensus statement regarding specific diagnostic and therapeutic issues in the management of individuals who present with DSD. The consensus statement includes recommendations for (1) laboratory workup, (2) acute management, (3) sex assignment in an ethical framework that includes education and involvement of the parents, and (4) surgical management.

Vaginal replacement in the pediatric age group: a 34-year experience of intestinal vaginoplasty in children and young girls

BACKGROUND/PURPOSE

The absence of vagina is rare in the pediatric population. It can occur as a result of congenital malformations such as an aplasia of mullerian ducts (46,XX Mayer-Rokitansky-Küster-Hauser syndrome) or a complete androgen insensitivity syndrome (46,XY testicular feminizing syndrome). Intersex patients, who underwent reassessment of a female sex, need a genital reconstruction toward a feminine phenotype. Patients with congenital adrenogenital syndrome with high urogenital sinus could have a severe hypoplastic vagina. In all these cases, a vaginal replacement is required. We reviewed our experience of vaginal replacement using a sigmoid conduit.

METHODS

In 34 years, we evaluated 47 patients. The observation period was from 1 to 34 years (mean: 12 years). The preoperative diagnosis was Mayer-Rokitansky-Küster-Hauser syndrome in 17 cases, androgen insensitivity syndrome in 24 cases, adrenogenital syndrome with high urogenital sinus in 5 and 1 patient was affected by penile agenesis. Forty-six patients were treated with vaginal reconstruction by interposition of sigmoid colon. Only in 1 case we performed a vaginal construction with an ileal loop: in this case, the sigmoid colon was extremely dilated by a chronic constipation secondary to a high anorectal malformation corrected at birth.

RESULTS

The outcome for 47 patients is excellent: 18 are sexually active and 4 are married. Only 1 patient with adrenogenital syndrome died of endocrine problems. Complications occurred in 17 cases: in 1 patient a necrosis of the replaced vagina occurred, thus requiring vaginal exeresis; now she is waiting for a second operation. Another patient had an abdominal abscess, which was surgically treated. In 12 cases a second procedure was required: 6 had stenotic new-vaginal introitus, 4 had new-vaginal prolapse, and 2 had intestinal obstruction.

CONCLUSIONS

We believe that the preferable technique for vaginal replacement is the use of intestinal conduit. The sigmoid colon is the best intestinal tract to be used owing to its size, location and preserved blood supply. Our experience leads us to believe that the sigmoid segment is the segment of choice, although we consider ileal loop as a good alternative when the sigmoid colon is not available.

Our 10-year experience of variable Müllerian anomalies and its management

PURPOSE

Though the Müllerian duct anomalies are rare in incidence, their variable age, and mode of presentation makes their management difficult.

METHODS

In the last 10 years authors managed 14 patients with different types of Müllerian anomalies. There were eight patients with complete Müllerian agenesis: three of partial Müllerian agenesis, one patient had uterine didelphys with vertical and transverse vaginal septum on left side, one patient had uterine didelphys with cervical agenesis on the right side, one patient had MRKH with anorectal malformation.

RESULTS

Patients with complete Müllerian agenesis underwent bowel vaginoplasty, and patients with partial Müllerian agenesis with hydrocolpos underwent pull-through vaginoplasty. Patient of uterine didelphys one with septum underwent septum excision and in another with cervical agenesis, cervix opened and drain kept. In MRKH with vestibular fistula, fistulous opening was kept as vaginal opening and rectum brought down as a neoanus.

CONCLUSION

Müllerian duct anomalies can present in any age group and with variable symptoms. Sigmoid colon vaginoplasty is an excellent procedure for complete or partial Müllerian agenesis. Correct evaluation of these patients and proper management is a challenge.

Mayer-Rokitansky-Küster-Hauser syndrome: sexuality, psychological effects, and quality of life

Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome is a congenital condition in which a genetic female is born with vaginal agenesis and a rudimentary to absent uterus. This condition affects a woman's ability to menstruate, to engage in penile-vaginal intercourse, and to bear children. Much has been published about how best to create a neovagina in women with MRKH, but little has been written about the psychological impact of MRKH and quality of life outcomes for women with the condition. A review of the extant literature published from 1955 to 2007 supports that (1) surgical or non-surgical creation of a neovagina alone does not ensure a successful psychological outcome, (2) psychological support at critical times can be helpful, and (3) how professionals use language to discuss the condition may positively or negatively influence a female's experience of MRKH. This article discusses the implications that existing knowledge has on future research and on clinical practice. Understanding how women with MRKH cope with and adjust to the condition will help healthcare professionals provide optimal care.

Disorders of sexual development

Disorders of sex development are medical conditions in which the development of chromosomal, gonadal, or anatomic sex varies from normal and may be incongruent with each other. This article primarily addresses the medical conditions where infants may be born with ambiguous genitalia leading to decisions with regard to gender assignment. The approach to investigations and diagnosis in the newborn period will be stressed within an interprofessional team. Policies with regard to surgery have developed, with techniques evolving and data emerging from long-term outcome studies. Current medical and surgical management are reviewed. Finally, a developmental approach to disclosure is presented.

[Anatomic and histological characteristics of vagina reconstructed by McIndoe method]

BACKGROUND/AIM

Congenital absence of vagina is known from ancient times of Greek. According to the literature data, incidence is 1/4 000 to 1/20 000. Treatment of this anomaly includes non-operative and operative procedures. McIndoe procedure uses split skin graft by Thiersch. The aim of this study was to establish anatomic and histological characteristics of vagina reconstructed by McIndoe method in Mayer Küster-Rockitansky Hauser (MKRH) syndrome and compare them with normal vagina.

METHODS

The study included 21 patients of 18 and more years with congenital anomaly known as aplasio vaginae within the Mayer Küster-Rockitansky Hauser syndrome. The patients were operated on by the plastic surgeon using the McIndoe method. The study was a retrospective review of the data from the history of the disease, objective and gynecological examination and cytological analysis of native preparations of vaginal stain (Papanicolau). Comparatively, 21 females of 18 and more years with normal vaginas were also studed. All the subjects were divided into the groups R (reconstructed) and C (control) and the subgroups according to age up to 30 years (1 R, 1C), from 30 to 50 (2R, 2C), and over 50 (3R, 3C). Statistical data processing was performed by using the Student's t-test and Mann-Writney U-test. A value of p < 0.05 was considered statistically significant.

RESULTS

The results show that there are differences in the depth and the wideness of reconstructed vagina, but the obtained values are still in the range of normal ones. Cytological differences between a reconstructed and the normal vagina were found.

CONCLUSION

A reconstructed vagina is smaller than the normal one regarding depth and width, but within the range of normal values. A split skin graft used in the reconstruction, keeps its own cytological, i.e. histological and, so, biological characteristics.

[Sensibility of vagina reconstructed by McIndoe method in Mayer-Rokitansky-Küster-Hauser syndrome]

BACKGROUND/AIM

Congenital absence of vagina is a failure present in Mayer-Küster-Rokitansky-Hauser syndrome. Treatment of this anomaly includes nonoperative and operative procedures. McIndoe procedure uses split skin graft by Thiersch. The aim of this study was to determine sensitivity (touch, warmness, coldness) of a vagina reconstructed by McIndoe method in Mayer-Küster-Rokitansky-Hauser syndrome and compare it with the normal vagina.

METHODS

A total of 21 female persons with reconstructed vagina by McIndoe method and 21 female persons with normal vagina were observed. All female persons were devided into groups and subgroups (according to age). Sensibility to touch, warmness and coldness were examined, applying VonFrey's esthesiometer and termoesthesiometer for warmness and coldness in three regions of vagina (enter, middle wall, bothom). The number of positive answers was registrated by touching the mucosa regions for five seconds, five times.

RESULTS

The obtained results showed that female patients with a reconstructed vagina by McIndoe method, felt touch at the middle part of wall and in the bottom of vagina better than patients with normal one. Also, the first ones felt warmness at the middle part of wall and coldness in the bottom of vagina, better than the patients with normal vagina. Other results showed no difference in sensibility between reconstructed and normal vagina.

CONCLUSION

Various types of sensibility (touch, warmness, coldness) are better or the same in vaginas reconstructed by McIndoe method, in comparison with normal ones. This could be explaned by the fact that skin grafts are capable of recovering sensibility.

Long-term outcome of vaginal reconstruction: comparing techniques and timing

OBJECTIVE

In a retrospective review, to analyse the long-term outcomes of vaginal reconstruction, comparing techniques and timing.

PATIENTS AND METHODS

We identified 63 patients who underwent a total of 71 vaginoplasties in 1985-2000. The techniques used were posterior skin flap (42), intestinal replacement (21) and pull through (8). The majority of operations were performed before puberty (63%) and as primary procedures (79%). Presenting diagnoses were congenital adrenal hyperplasia (23), cloacal exstrophy (8), true persistent cloaca (12), androgen insensitivity (8), urogenital sinus anomaly (6), mixed gonadal dysgenesis (3), true hermaphroditism (2) and sacrococcygeal teratoma (1).

RESULTS

The mean age at operation was 83.9 (2-235) and mean follow up was 116.8 (48-232) months. Strictures and discharge were the most common problems. Nine patients underwent revision surgery and a fistula repair was required in two patients. Mucosal prolapse was observed in one ileo- and one colovaginoplasty patient, and diversion colitis occurred after colovaginoplasty in one patient. More complications occurred in operations performed prior to than following puberty.

CONCLUSION

If vaginoplasty is the only indicated operation, delaying until puberty may minimize complications. When other genital surgery is indicated or in the presence of symptoms pre-pubertal vaginoplasty should be performed, since the second procedure usually involves simple dilatations and is associated with good results.

Ambiguous genitalia: an overview of 17 years' experience

AIM

The newborn with abnormal genital development presents a difficult diagnostic and treatment challenge for the pediatric surgeon providing care. The purpose of this study was to evaluate the results of surgical treatment for children with ambiguous genitalia.

PATIENTS AND METHODS

The records of 85 children managed surgically for ambiguous genitalia in our unit from 1988 to 2005 were reviewed retrospectively. Age at surgery, operative procedures, sex of rearing, and outcome were recorded.

RESULTS

The intersex committee's decision concerning sex assignment was female for 62 children (75%) and male for 23 children (25%). The etiologies of children reared as female were congenital adrenal hyperplasia (n = 37), male pseudohermaphroditism (n = 12), mixed gonadal dysgenesis (n = 6), true hermaphroditism (n = 4), and Mayer-Rokitansky syndrome (n = 3). Fifteen children with male pseudohermaphroditism, 5 children with congenital adrenal hyperplasia, and 3 children with true hermaphroditism were reared as male. The mean age at surgery was 4.4 years and follow-up period averaged 7 years. Eighteen (29%) patients with feminization procedures and 8 (34%) of 23 patients with masculinization procedures experienced complications and required redo operations. Vaginal stenosis was the most common complication.

CONCLUSION

The surgical management of ambiguous genitalia has always been difficult, and it must be performed by skilled pediatric surgeon. Genital surgery in infancy needs to be reassessed in the light of literature findings revealing poor outcome. In patients who underwent feminizing genitoplasty, vaginal reconstruction should be delayed until adolescence to achieve better cosmetic and functional results.

The approach to a neonate with a possible prenatal diagnosis of androgen insensitivity syndrome

The diagnosis of androgen insensitivity syndrome (AIS) can now be made prenatally. We present a patient for whom the diagnosis of AIS was highly suspected prenatally, but the parents preferred to deny it. The clinical findings and the diagnostic evaluation after delivery are presented. A brief discussion of the syndrome, as well as the implications of possible prenatal diagnosis and how to approach it, are provided. Full multidisciplinary diagnostic work-up immediately after delivery, as well as awareness of possible prenatal diagnosis, is the responsibility of the primary care provider for the newborn with suspected AIS.

Sexualmedizinische Aspekte bei Intersexsyndromen

Disorders of somatosexual development that lead to ambiguous genitalia occur in one from 3,000-5,000 newborns. Parents and health care professionals are confronted with a number of crucial questions: to what sex should the child be assigned, what is the appropriate treatment in terms of hormonal and surgical interventions, when and how should these take place, and what impact do they have on the development of gender identity (GI), psychosexual well-being and fertility? This paper reviews the etiology, treatment and outcome in terms of GI and sexual health for the following syndromes: congenital adrenal hyperplasia (CAH), complete and partial androgen insensitivity (cAIS, pAIS), and pure and mixed gonadal dysgenesis (pGD, mGD). Emphasis is focussed on the current discussion involving the timing and extent of genital surgery. Finally, a procedure is introduced that covers the sexual-medical needs of patients, parents and health care professionals.

Congenital adrenal hyperplasia in adults: a review of medical, surgical and psychological issues

Our knowledge of the experience of adults with congenital adrenal hyperplasia (CAH) as they pass through life is only now emerging. In this review we gather medical, surgical and psychological literature pertaining to adults with CAH and consider this alongside practical experience gained from a dedicated adult CAH clinic. There is increasing awareness for the need for multidisciplinary teams who have knowledge of CAH particularly with respect to gynaecological surgery and clinical psychology for women and testicular function in men. Routine management of CAH comprises adjustment of glucocorticoid and mineralocorticoid treatment according to individual needs balancing biochemical markers, compliance and long term risks. Bone density is one such long term concern and is not greatly reduced in most individuals with CAH. More recently, attention has turned to cardiovascular risk factors and catecholamine deficiency in adults with CAH. Women with CAH require access to an experienced gynaecologist, specialised pregnancy care and psychosexual support. The very low fertility rates for women with CAH previously reported appear to be improving with time. Men with CAH are often lost to follow up and therefore miss out on surveillance for hypogonadism either through the effect of adrenal rests of from suppression of gonadotrophins resulting in a high prevalence of oligospermia.

Intersex conditions in children and adolescents: surgical, ethical, and legal considerations

INTRODUCTION

Approximately one in 2000 children globally is born with an intersex condition. There is unfortunately a relative paucity of data on the choices and the surgical and psychosocial outcomes in patients who undergo genital surgery for intersex conditions and ambiguous genitalia, especially in developing countries. Specialists in these and other countries, where patient follow-up is generally poor, are faced with the daunting task of offering the appropriate medical and surgical management, in the absence of guidelines or recommendations.

SURGICAL CONSIDERATIONS

A surgical procedure in these patients sometimes involves clitoral recession, reduction, vaginoplasty, and gonadectomy. The best surgical outcome is likely to be achieved with a multidisciplinary surgical team; however, the choice of surgery and appropriate timing remains controversial. Some authors have suggested delaying surgery until the child becomes competent to make his/her own decisions.

LEGAL/ETHICAL CONSIDERATIONS

All procedures should conform to an ethical code of practice and be in the interest of the child. Exhaustive counseling of all parties and informed consent is of paramount importance, as is adherence to laws that protect the rights of the child as outlined in respective constitutions.

RECOMMENDATIONS

Recommendations in this article, which have been put together from the combined input of three departments, are broad-based. They emphasize the need for extensive counseling, informed consent, adherence to ethical and legal norms, a multidisciplinary input and a shift away from a paternalistic approach.

Mobilização total do seio urogenital para tratamento da genitália ambígua em crianças com hiperplasia adrenal congênita

A abordagem cirúrgica das pacientes com hiperplasia adrenal congênita (HAC) é um desafio e envolve controvérsias. O objetivo deste estudo é avaliar os resultados da correção da genitália em 10 crianças 46 XX com HAC, pela técnica de mobilização total do seio urogenital (MUT), em tempo único. A idade, por ocasião do tratamento cirúrgico, variou de 11 a 78 meses (média= 32 meses) e o seguimento pós-operatório de 15 a 36 meses (média= 26 meses). O aspecto estético foi considerado bom em 7, com uretra e vagina bem exteriorizados no vestíbulo, e satisfatório em 3. Após o acompanhamento médio de 26 meses, a técnica de MUT, por via perineal, sem divisão do reto, se mostrou eficaz para o tratamento da genitália ambígua em crianças com HAC.

Minimal surgical intervention in the management of intersex conditions

The surgical correction of ambiguous genitalia has been a significant part of treatment for intersex conditions for the last 50 years, based on the belief that the child will be psychologically damaged by the uncorrected appearance. Despite widespread adoption of this policy, there is no evidence in the literature to support this approach. More commonly, the primary indication appears to be for the relief of parental anxiety. However, patients are increasingly expressing dissatisfaction with previous management, arguing that surgery should only be performed for strictly defined medical indications. Surgery may comprise treatment for the absent or shortened vagina, or for the correction of virilised external genitalia. The timing of such surgery is controversial, with many surgeons believing that a 'one-stage' procedure in infancy is appropriate. However, given that the vast majority of patients require further surgery at adolescence, others argue that deferral of vaginal surgery until after puberty is more appropriate. The role of clitoral surgery is contentious with many questioning the necessity of any operation in childhood for cosmesis which may impair subsequent sexual function. Despite claims that newer surgical techniques lead to a better result than previously, there remains little information in the literature regarding long-term functional outcomes following clitoral reduction procedures. Alternatives to vaginal and clitoral surgery are considered in this article. Vaginal operations should almost always take place at adolescence, given the poor outcomes of early surgery. When clitoral operations are performed, this should be for severely virilised individuals, with surgery best avoided for those with only mild or moderate virilisation.

Vaginal and penile reconstruction

PURPOSE OF REVIEW

Reconstructive surgery for patients with genital abnormalities or for patients who require reconstructive efforts is challenging. This review highlights those articles, which are outstanding among all those important papers, which have been published during the last year (2002-2003).

RECENT FINDINGS

A greater understanding of embryonal development improves the success of reconstructive surgery. Other factors, such as the patient's sex, influence the surgical technique used and the degree of invasiveness or complexity. In the adult the pressure to shorten hospital stays has played a big part in the continual modification and enhancement of surgical techniques. In addition to modified techniques, new off-the-shelf materials are introduced to the clinic, which seem to have the potential to improve the surgical outcome and shorten hospital stays.

SUMMARY

With the continued successful basic anatomy and basic research, reconstructive surgery brings higher success rates. Long-term results are still required to validate the reliability of these new surgical techniques and materials.

Treatment of vaginal atresia at a missionary hospital in Bangladesh: results and followup of 20 cases

PURPOSE

We report a 9-year experience with successful treatment of patients with vaginal atresia at a missionary hospital with decreased facilities in Bangladesh.

MATERIALS AND METHODS

From 1995 to 2002, 20 patients 10 to 29 years old (average age 18.4) with Mayer-Rokitansky-Kuster-Hauser syndrome underwent total vaginal replacement. Ten of the 20 females were married and the anomaly was discovered after marriage. In the remaining 10 cases the diagnosis was suspected by the parents because of absent menstruation. In all patients the neovagina was created using a 12 to 14 cm segment of distal sigmoid colon.

RESULTS

Short-term morbidity was minimal. At the long-term followup, which was available for 16 patients, the neovagina had a good-appearing introitus. No stenosis, stones or colitis was reported. Six patients already had an active sexual life, which was reported to be satisfactory. Five couples had already adopted 1 or more children.

CONCLUSIONS

Good perioperative preparation and assistance, assurance of cyclical followup and a trained surgical team permitted successful treatment of a complex genital malformation at a missionary hospital with modest services. Sigmoid vaginoplasty in a developing country seems to be the best choice because of simple management and followup. Young women unable to procreate because of vaginal atresia seem to have an unexpected normal family and social acceptance in Bangladesh after complete vaginal replacement.

Laparoscopic approach to müllerian derivatives in a male with mixed gonadal dysgenesis

Müllerian derivatives are a frequent finding in patients with external genital ambiguity. In cases in which their removal is indicated, traditional surgical approaches are both invasive and associated with risks. We report a case of mixed gonadal dysgenesis in which a large prostatic utricle was successfully removed via laparoscopy.
