Parent perspectives of health related quality of life for adolescents with bladder exstrophy-epispadias as measured by the child health questionnaire-parent form 50

BEEC psychosocial screening at Royal Manchester Children's Hospital

INTRODUCTION

Bladder Exstrophy and Epispadias Complex (BEEC) is associated with psychosocial difficulties. Screening questionnaires, alongside consultation with a clinical psychologist, can help identify children/young people for further assessment and track trends over time to improve service delivery.

OBJECTIVE

To screen paediatric BEEC patients for a range of general psychosocial difficulties in a multi-disciplinary out-patient clinic setting and compare these results with our previous study and against published norms.

STUDY DESIGN

The current service evaluation collected data at outpatient BEEC clinic appointments between 2016 and 2022 (2016-2022 sample). Children aged 4-5, 10-11 and 14-15 years and their parents/proxy were asked to complete two standardised psychosocial questionnaires: Paediatric Quality of Life Inventory (PedsQL 4.0 Generic Core and Family Impact Module) and the Strengths and Difficulties Questionnaires (SDQ). 79 children (CYP) and 93 parent/proxy (P/P) responses were recorded. The sample included paired CYP and P/P responses for the PedsQL (n = 67) and SDQ (n = 35). The mean age for CYP was 9.9 years (SD 3.99, range 2-17), 69.8% (n = 120) of responses for male children.

RESULTS

The percentage of total CYP scores falling within the 'At Risk' category on the PedsQL increased in the 2016-2022 sample compared to our 2015 sample, indicating the prevalence of greater difficulties. Differences between P/P and CYP responses on both the PedsQL and SDQ favoured CYP. Age, gender, and diagnosis appeared to influence certain questionnaire responses, depending on respondent (CYP or P/P). A significant difference between P/P and CYP in the emotional domain of the PedsQL for those aged 13-18 was observed (p = 0.020), with P/P reporting greater difficulties, but this was not seen in the younger age ranges. Physical Health on the PedsQL were significantly lower for children with a cloacal exstrophy diagnosis, in comparison to bladder exstrophy and epispadias. P/P SDQ scores for boys were significantly higher in several domains.

CONCLUSIONS

The results demonstrate the need for psychosocial screening, providing benchmarking for psychosocial difficulties within this patient group. Results indicate that patients accessing our clinic are reporting a higher level of challenge across psychosocial domains in recent years reflected by the percentage within the 'At Risk' category for psychosocial difficulty. Linked questionnaire data with condition specific information and surgical history would improve service evaluations. CYP reaching clinical thresholds are offered further psychological assessment within the service.

The Effect of Multiple Surgeries on Psychosocial Outcomes in Pediatric Patients: A Scoping Review

BACKGROUND

Birth defects affect 3% of all babies born in the United States each year. Unlike reconstruction for many acquired deformities, one hallmark of reconstruction for complex congenital conditions is the requirement of multiple surgeries, procedures, and therapies from birth to maturity. These interventions often result in significant medical burden on children during development with potential long-term psychosocial consequences. The aim of this study was therefore to better define the psychosocial impact of repetitive operations on the pediatric patient.

METHODS

A scoping review was performed under the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Review guidelines. We searched the PubMed, Cochrane Library, Science Direct, and Web of Science databases using key words "number of surgeries," "psychosocial," "pediatric," and related terms. Primary articles published in English describing psychosocial outcomes in pediatric patients who underwent more than one procedure or surgery were included (n = 25). The Newcastle-Ottawa Scale was used to assess the quality of each study.

RESULTS

We included 25 articles published between 1995 and 2019, which included 6520 patients. The most common diagnosis across all studies was congenital heart disease (CHD) (n = 4169, 63.9%), followed by cleft lip and palate (n = 1196, 18.3%). The average number of operations and procedures was 3.4 (range = 1-18) and 32.1 (range = 6-89), respectively. The association between repetitive surgeries and poorer psychosocial outcomes was demonstrated in children with early-onset scoliosis, CHD, hydrocephalus, bladder exstrophy, posterior urethral rupture, anorectal anomalies, and conditions requiring numerous nonsurgical procedures. There were also a few CHD, cleft lip and/or palate, and hydrocephalus studies that did not find a significant correlation.

CONCLUSIONS

The studies here suggest that certain pediatric patient populations are at risk for impaired psychosocial functioning as a result of repetitive procedures. However, it is important to differentiate whether the association with poorer psychosocial outcomes is from the number of surgical procedures or whether the number if just a surrogate for increased disease complexity. Standardized psychosocial outcomes measures and future prospective, long-term, randomized clinical trials are also warranted.

Health-related quality of life among children, adolescents, and adults with bladder exstrophy-epispadias complex: a systematic review of the literature and recommendations for future research

PURPOSE

Bladder exstrophy-epispadias complex (BEEC) is a rare spectrum of genitourinary malformations. Children risk long-term urinary and genital dysfunctions. To achieve a comprehensive understanding, this study aimed to review the literature on generic and disease-specific health-related quality of life (HRQOL) in BEEC patients, and methodologies used.

METHODS

A literature search was conducted in Pubmed/CINAHL/Embase/PsycINFO/Cochrane, from inception to May 2018. A meta-analysis of HRQOL in BEEC patients compared to healthy references was performed.

RESULTS

Twenty-one articles (published 1994-2018), describing HRQOL of children and adolescents (n = 5) and adults only (n = 5), or integrated age populations (n = 11), were identified (median sample size 24, loss to follow-up 43%, response rate 84%). Overall HRQOL was reduced in BEEC patients compared to healthy references in 4/4 studies. Impaired physical or general health in BEEC patients has been described in 9 articles, diminished mental health in 11, restricted social health in 10, and sexual health/functioning or body perception impairments in 13 articles. Urinary incontinence was the most common factor related to worse HRQOL (12 studies). In six studies, HRQOL was better than healthy norms. In eligible studies (n = 5), the pooled estimate of the effect of BEEC indicated worse HRQOL for children and adults (0 > effect sizes < 0.5). Thirty-six HRQOL assessments were used, none developed and validated for BEEC.

CONCLUSIONS

HRQOL in BEEC patients may be negatively impacted, particularly considering mental and social HRQOL. Sexual health/functioning or body perception impairments may be present in adolescents and adults. However, HRQOL is heterogeneously assessed and subsequent findings are differently reported. Additional research is warranted and can be improved.

Exstrophy Bladder - Reconstruction or Diversion for the Underprivileged

The surgical techniques for management of bladder exstrophy epispadias complex have evolved from staged reconstruction, complete primary repair to radical mobilization. Post-operative complications add to the multiplicity of surgical procedures at each step. The end results are variable with many achieving continence rates of 85-89% only after bladder augmentation and clean intermittent catheterization. The situation is further complicated in resource-poor settings, where illiteracy and poverty are the driving factors for choosing a single operative procedure for creation of low pressure reservoir aiming at upper tract preservation and good primary continence. Thus, primary urinary diversion should be offered as a surgical option to patients with limited access to health care facilities. Yogesh's cystorectostomy is a modification of Heitz-Boyer-Hovelacque procedure, wherein the bladder plate is directly anastomosed to the recto-sigmoid pouch, without mobilizing the ureters from their original location. The short-term follow-ups are encouraging with all achieving total urinary continence over the ensuing months. The upper tract functions are well preserved, along with huge parental and patient satisfaction and overall improvement in the quality of life.

Qualitative questionnaire on the psychosocial wellbeing of mothers of children with BEEC

INTRODUCTION

The bladder exstrophy-epispadias complex (BEEC) represents a spectrum of malformations that affect the anatomical and functional structure of the urogenital system. The parents of patients affected by this condition are subject to particularly stressful situations, such as worrying about their child's health, long hospital stays, concerns about the health and constant need for personal care for their children, that can profoundly compromise the quality of family life.

OBJECTIVE

The objective of this explorative qualitative study is to evaluate the social situation and the psychological strategies implemented by the mothers of children between 6 and 10 years of age who are affected by BEEC.

STUDY DESIGN

Fourteen mothers of children aged 6-10 years and affected by BEEC (9 boys and 5 girls) were interviewed. Data on the mothers' experiences were collected through semi-structured interviews (Table).

RESULTS

The qualitative analysis of the interviews showed that participants described experiences that were characterised by emotions such as fear and anger. Each mother had implemented a different and, sometimes, dysfunctional strategy in order to cope with the complex situation of the son/daughter. The aspects that most clearly emerged from mothers' descriptions were (1) the traumatic situation at the birth of the baby, (2) the sense of embarrassment concerning the pathological condition as the child was growing and the consequent sense of isolation of the mother, and (3) the fluctuation of feelings towards the multidisciplinary staff, which was sometimes seen as an important source of help and some other times as too destabilising and not helpful at all.

DISCUSSION

The study provided some insight into the psychological and social conditions experienced by mothers of children with BEEC, which could serve as a basis for developing multidisciplinary teams with greater awareness about families living with this condition and better timing in addressing their needs.

CONCLUSIONS

Mothers of children with BEEC show emotional and social difficulties. This is a crucial aspect to consider when planning a multidisciplinary approach to the treatment/therapy, especially considering that children examined in this study are approaching adolescence.

Low-dose Human Chorionic Gonadotropin Stimulation Test as a Prognostic Incontinent Indicator in Boys With Bladder Exstrophy-epispadias Complex

OBJECTIVE

To investigate the effect of low-dose human chorionic gonadotropin (HCG) administration on structural changes in the lower urinary tract in boys with urinary incontinence in the setting of bladder exstrophy-epispadias complex (BEEC).

PATIENTS AND METHODS

We prospectively evaluated 30 patients (median age 7.5 years) with BEEC and randomly divided them into 2 groups. Patients in the HCG group were administered 250 IU HCG intramuscularly 3 times per week during a 4-week period. The other 15 patients served as the control group. The patients were followed up for a mean duration of 4 years. Incontinence rate, hormonal changes, penile length, prostate size, and bladder capacity were evaluated using 3D sonography or pelvic magnetic resonance imaging and uroflowmetry studies before and after HCG administration.

RESULTS

The incontinence score improvement was significantly higher in the HCG group (P = .01). A significant increase was detected in the health-related quality of life score of both patients and parents at the final follow-up (P < .001). The total prostate size (P < .0001) and bladder capacity (P < .0001) increased significantly in all patients of the HCG group. Basal serum testosterone level increased significantly after the first (P = .001) and last (P < .001) injections with no significant increase 3 months after the last injection (P > .05). No major side effect was found following the administration of HCG, with no need for open surgical bladder neck reconstruction.

CONCLUSION

Our preliminary results suggest the role of low-dose HCG in boys with BEEC suffering from urinary incontinence. The data also reveal the role of prostate enlargement in the improvement of urinary incontinence. Chronic treatment with HCG increases bladder capacity that may facilitate future reconstructive surgery.

Role of routine cystoscopy and cystography in exstrophy-epispadias complex

OBJECTIVE

Our institutional protocol for the treatment of exstrophy-epispadias complex includes routine endoscopic and cystographic evaluation of the bladder with the child under general anesthesia. The protocols briefly described in the literature include a cystographic evaluation and the measurement of bladder capacity, but there are no reports on concurrent endoscopic findings and the value of examinations in this setting. Our objective is to evaluate the role and necessity of our management protocol by reviewing the findings in our patients' medical charts.

STUDY DESIGN

Cystoscopies are performed in children with exstrophy-epispadias complex during the second year of life and then every 18 months until a capacity of 90 mL has been reached and bladder neck reconstruction, the last stage of modern staged repair, is performed. Patients referred from other institutions are evaluated on presentation. The examinations are performed by means of a pediatric cystoscope with the child under general anesthesia. Cystography is performed under a pressure of 30 cm/H2O. The contribution of the findings of these periodic evaluations vis-à-vis the surgical findings were studied.

RESULTS

The medical charts of 49 patients who had been surgically treated for exstrophy-epispadias complex in our institution between 2000 and 2014 were reviewed. Thirty patients underwent at least one evaluation. Eighteen underwent serial examinations: four underwent two procedures, eleven underwent three procedures, and three underwent four procedures. The findings in eight cases were significant and they were treated on detection: bladder neck stricture (n = 5), bladder scar bridge (n = 2), and bladder stone (n = 1). Vesicoureteral reflux was present in all 30 patients, and high-grade reflux was present in 10 patients, of whom four had a bladder neck stricture. Fourteen of the 30 patients had a bladder capacity of 90 mL on the first evaluation, as did an additional eight children during later evaluations. Bladder capacity decreased below 90 mL in one child. Seven children did not reach the target capacity (Figure).

CONCLUSION

Cystoscopic and cystometrographic evaluation of an exstrophic bladder allows early diagnosis of treatable bladder pathologies and monitoring of bladder capacity. It is a valuable tool in the follow-up period preceding bladder neck reconstruction.

The Posterior Sagittal Approach to Bladder Neck Closure in Patients With Anorectal Malformation: A Novel Collaborative Technique

Bladder neck closure may be beneficial in patients with refractory urinary incontinence secondary to outlet deficiency. The location of the bladder neck deep within the pelvis may make exposure difficult during an open approach. We describe a novel approach to bladder neck closure in patients with anorectal malformations using a posterior sagittal approach. Our approach provides superior visualization of the bladder neck and easy access to tissue to provide additional layers of coverage, and prevents the need for an abdominal incision in patients undergoing simultaneous rectal or vaginal surgeries.

Psychosocial screening at paediatric BEEC clinics: a pilot evaluation study

INTRODUCTION

Bladder Exstrophy and Epispadias Complex (BEEC) is associated with an increased risk of impaired mental health, quality of life, and psychosocial functioning. Therefore, screening patients to help identify and evaluate potential psychosocial difficulty is arguably an important consideration for BEEC Services.

OBJECTIVE

To screen paediatric BEEC patients for a range of general psychosocial difficulties in a multi-disciplinary out-patient clinic setting.

STUDY DESIGN

This cross-sectional evaluation was conducted between April 2012 and July 2013. Families attending BEEC multi-disciplinary out-patient clinics were asked to complete a range of standardised psychosocial questionnaires, including the Paediatric Quality of Life Inventory (PedsQL 4.0 Generic Core and Family Impact Module), the Strengths and Difficulties Questionnaire (SDQ), the Paediatric Index of Emotional Distress (PI-ED), and the Hospital Anxiety and Depression Scale (HADS). 108 children attended clinic of which 80 (74.1%) patients and their parents/carers completed some or all of the questionnaires. The mean patient age was 8.41 years (SD = 4.46, range = 1-18 years). There were more boys (N = 50, 62.5%) and the majority had a diagnosis of classic bladder exstrophy (N = 51, 63.8%), followed by primary epispadias (N = 22, 27.5%) and cloacal exstrophy (N = 7, 8.7%).

RESULTS

Mean total scores fell within the average/normal range on all questionnaires used (See table below). However, variation around these means was high. Age, gender and diagnosis were found to significantly influence certain questionnaire responses with older-age groups, males, and those with classic bladder exstrophy particularly at risk across some domains. The children/adolescents self-reported better health related quality of life (HRQoL) scores than published results for a range of paediatric chronic health conditions. Differences between parent and child responses on both the PedsQL and SDQ favoured a more positive response on the child self-report questionnaire but were not statistically significant.

DISCUSSION

Mean scores on the measures used suggest a relatively optimistic picture of general psychosocial well-being, especially for HRQoL, in the BEEC population studied. Positive HRQoL outcomes have recently been reported for BEEC paediatric populations. Our results reflect this trend with better mean HRQoL scores than paediatric patients with a range of other chronic health conditions. However, this optimism is cautious given the limitations of this evaluation study and the high variation around the means. Limitations included the small sample size (especially for patients with cloacal exstrophy), the lack of a control group, the limited sensitivity of generic questionnaires in respect of BEEC-specific issues, and the low mean age of patients in the study. Future screening programmes may wish to consider measuring BEEC-specific variables (e.g. satisfaction with genital appearance/function); collecting information on medical aspects, such as continence, pubertal stage and frequency/timing of medical intervention; and asking both parents/carers (where possible) to complete the questionnaires.

CONCLUSIONS

Screening questionnaire responses were used in conjunction with clinical psychology consultations to evaluate a range of psychosocial aspects in BEEC paediatric patients. Whilst mean scores on the measures used suggest a relatively optimistic picture, certain individual scores did fall within the clinical ranges, highlighting the potential need for further assessment. Developmentally tailored consultations with a clinical psychologist can provide detailed information around questionnaire responses and further assess BEEC specific aspects.

Aesthetic, urological, orthopaedic and functional outcomes in complex bladder exstrophy-epispadias's management

BACKGROUND

Postoperative complications are related to the surgical procedures, of failures of initial bladder closure and influence the urological, aesthetical and orthopaedic outcomes.

MATERIALS AND METHODS

We reviewed four patients who underwent complex bladder exstrophy-epispadias repair over a period of 14 years. The outcomes of treatment were assessed using, aesthetic, urological and orthopaedic examination data. Orthopaedic complications were explored by a radiography of the pelvis.

RESULTS

Out of four patients who underwent bladder exstrophy surgical management, aesthetic, functional outcomes and complications in the short and long follow-up were achieved in three patients. The first patient is a male and had a good penis aspect. He has a normal erection during micturition with a good jet miction. He has a moderate urinary incontinence, which requires diaper. In the erection, his penis-measures 4 cm long and 3 cm as circumference. The second patient was a female. She had an unsightly appearance of the female external genitalia with bipartite clitoris. Urinary continence could not be assessed; she did not have the age of cleanness yet. The third patient had a significant urinary leakage due to the failure of the epispadias repair. He has a limp, a pelvic obliquity, varus and internal rotation of the femoral head. He has an inequality of limbs length. Pelvis radiograph shows the right osteotomy through the ilium bone, the left osteotomy through the hip joint at the acetabular roof.

CONCLUSION

When, the epispadias repair is performed contemporary to initial bladder closure, its success is decisive for urinary continence. In the female, surgical revision is required after the initial bladder closure for an aesthetic appearance to the external genitalia. Innominate osteotomy must be performed with brilliancy amplifier to avoid osteotomy through to the hip joint to prevent inequality in leg length.

Indiana pouch in children: a 15-year experience

OBJECTIVE

We report our experience with the Indiana pouch (continent urinary reservoir) in 12 consecutive children over the last 15 years and report their follow-up.

MATERIAL AND METHODS

Twelve consecutive children, who underwent the continent urinary reservoir procedure in the form of an Indiana pouch, were prospectively enrolled in the study. All consecutive children who were referred to our service with multiple failed surgeries for exstrophy-epispadias repair, cloacal exstrophy, genitourinary rhabdomyosarcoma with residual disease in the trigonal area not amenable to partial cystectomy, and neuropathic bladder with nephrogenic metaplasia were included over the period 1997-2012. All these children were offered the same form of bladder substitution (Indiana pouch) as described by the Indiana group many years ago. Postoperative care was on a fixed protocol, and follow-up details recorded over the years. They were followed up for dry interval with clean intermittent catheterisation, social acceptance, and early and late complications.

RESULTS

Out of these 12 patients (7 males and 5 females), eight patients had exstrophy-epispadias with multiple failed operations carried out elsewhere, cloacal exstrophy (2), residual rhabdomyosarcoma in the trigonal area with incontinence following chemotherapy (1), and neuropathic bladder with recurrent diffuse neoplastic polyposis (1). In the follow-up period of 1-15 years (median 24 months) all the patients had a dry interval of 4 h or more with clean intermittent catheterisation. One patient had wound dehiscence during the postoperative period and another required stomal revision 1 year after initial surgery.

CONCLUSIONS

The Indiana pouch is a reliable, safe, and effective form of bladder substitution. It can be reconstructed in a wide range of lower urinary tract disorders. In the vast majority of children with multiple failed surgical procedures for exstrophy-epispadias, the Indiana pouch is a safe, reliable, and reproducible procedure to provide a socially acceptable quality of life with a dry interval of 4 h.

New advances in the pathophysiologic and radiologic basis of the exstrophy spectrum

The exstrophy-epispadias complex is a rare spectrum of anomalies affecting the genitourinary system, anterior abdominal wall, and pelvis. Recent advances in the repair of classic bladder exstrophy (CBE) and cloacal exstrophy (CE) have resulted in significant changes in outcomes of surgical management (including higher continence rate, fewer surgical complications, and better cosmesis) and health-related quality of life in these patients. These noteworthy changes resulted from advances in the pathophysiological and genetic backgrounds of this disease and better radiologic assessment of the three-dimensional anatomy of the bony pelvis and its musculature. A PubMed search was performed with the keyword exstrophy. The resulting literature pertaining to genetics, stem cells, imaging, tissue engineering, epidemiology, and endocrinology was reviewed. The following represents an overview of the advances in basic science understanding and imaging of the exstrophy-epispadias spectrum and discusses their possible and future effects on the management of CBE and CE.

Emotional and behavioral functioning in children with bladder exstrophy-epispadias complex: a developmental perspective

OBJECTIVE

To evaluate the emotional and behavioral functioning of children with bladder exstrophy-epispadias complex (BEEC), taking into account developmental and gender considerations. This study also sought to overcome methodological limitations of previous studies evaluating psychological well-being of children with BEEC.

METHODS

Eighty-six children were consecutively evaluated using the parent report version of the Behavior Assessment System for Children during visits to a multidisciplinary urology clinic.

RESULTS

Results indicated normative emotional and behavioral functioning across the sample. However, there was a significant effect of age, such that older children consistently had worse internalizing symptoms and adaptive functioning. Males tended to have more externalizing problems as they aged, and also tended to have lower levels of adaptive functioning but this was independent of age. The level of psychological impairment was unrelated to the specific type of BEEC, and was also unrelated to whether or not the patient had undergone continence surgery.

CONCLUSION

Children with BEEC have a greater likelihood of experiencing a wide range of emotional and behavioral problems as they reach adolescence. These findings point to the need to prevent potential psychological distress by intervening with these children before they become clinically impaired.

Exstrophy epispadias complex- Issues beyond the initial repair

Despite advances in the management of exstrophy epispadias complex (EEC), the quality of life of these patients is far from good. The post-operative period is complicated by numerous and variable events - infection, dehiscence, upper tract dilatation with deterioration, fistulas, stone formation and incontinence to name a few of the major complications. Redo surgery for bladder closure, bladder neck reconstruction, epispadias repair and closure of fistulas are frequently required. The current focus is on limiting the frequency and morbidity of the reconstructive procedures. A successful initial closure and early satisfactory cosmetic and functional results are gratifying for the family and the health care team, but this is only the beginning of the lifelong care necessary for bladder exstrophy (BE) patients. In this article, the long-term outcome of various treatment options and the continent procedures in BE has been reviewed, tracing the journey of these patients into adolescence and adulthood.

Health related quality of life in adolescents with bladder exstrophy-epispadias as measured by the Child Health Questionnaire-Child Form 87

PURPOSE

We determined health related quality of life as reported by adolescents with bladder exstrophy or epispadias using a validated generic instrument.

MATERIALS AND METHODS

Adolescents age 11 to 18 years with bladder exstrophy or epispadias (57) completed a validated, generic, health related quality of life instrument, the CHQ-CF87 (Child Health Questionnaire-Child Form 87). Urinary incontinence, catheterization status, and medical and surgical history data were also obtained. Mean summary scores and 95% CIs for each subdomain of the CHQ-CF87 were calculated, and descriptively compared to 2 population based samples. In our sample health related quality of life outcomes by continence status were compared using univariate and multivariate analysis. However, this analysis was limited by a small sample size.

RESULTS

Mean age of the 49 patients with bladder exstrophy and the 8 with epispadias was 14.3 years, 67% were male and 81% were Caucasian. There were 31 participants who reported incontinence and the median number of lifetime surgeries was 9. The exstrophy population scored well in all subdomains of the instrument when descriptively compared to 2 large samples of adolescent populations. In our sample incontinent patients had lower scores by multivariate analysis in 7 of 10 domains and better scores in 3 of 10 domains, although these differences were not statistically significant.

CONCLUSIONS

Adolescents with bladder exstrophy and epispadias reported relatively good scores on the CHQ-CF87 when descriptively compared to other reference populations. This finding suggests that these children adapt well to the challenges of their condition. Analysis of the association of incontinence with health related quality of life was limited by the small sample size.

Safety, efficacy and health related quality of life of autologous myoblast transplantation for treatment of urinary incontinence in children with bladder exstrophy-epispadias complex

PURPOSE

Children with bladder exstrophy-epispadias complex undergoing endourethral autologous myoblast transplantation to treat urinary incontinence were evaluated at 4 years of followup regarding the safety, efficacy and durability of the procedure, and health related quality of life.

MATERIALS AND METHODS

Seven boys underwent autologous myoblast transplantation between May and December 2006. All patients had persistent urinary incontinence after bladder neck reconstruction and bulking agent injection. Patients were followed for 4 years after autologous myoblast transplantation regarding clinical outcomes and cystometric, urodynamic, uroflowmetric and urethrocystoscopic evaluations. Health related quality of life was also measured before treatment and at final followup.

RESULTS

No evidence of urinary obstruction was observed. Five children (71%) were completely continent and 2 (29%) were socially dry with complete daytime dryness at final followup. Health related quality of life was improved significantly. Urodynamic studies revealed a progressive increase in bladder capacity (p <0.001). Mean detrusor leak point pressure showed a 27 cm H(2)O (158%) increase during 4-year followup. Uroflowmetry parameters of voided volume and average maximum flow rate were improved significantly (p <0.001).

CONCLUSIONS

The 4-year outcomes demonstrate that autologous myoblast transplantation for urinary incontinence in children with bladder exstrophy-epispadias complex is relatively reliable, reproducible, safe and effective with minimal morbidity. This novel treatment represents a promising therapeutic approach in patients with urinary incontinence. Further randomized trials with larger numbers of patients and longer followup are needed.
