RESUMO
AIMS: We evaluated the long-term results with a left antegrade continence enema (LACE) approach: "Macedo-Malone (MM) procedure" to define parameters such as clinical durability of the technique and patients' compliance with the method. METHODS: We reviewed the medical records of all patients that underwent the MM procedure in our institution since 2001 and conducted a telephonic interview to investigate the use of the enema and satisfaction with the procedure. RESULTS: Thirty-five MM procedures were performed, but eight patients lost to follow-up were excluded. Fifteen patients (55%) were female. Myelomeningocele was the clinical diagnoses in 25 (93%). Mean age at surgery was 9 years (3-27 years) and mean follow-up was 75 months (median: 56 months). The indication for LACE was clinically intractable constipation with fecal leakage. Most patients still used the stoma regularly to do the enema (74%). Mean washout time was 27 min (2-90 min). The revision rate due to stenosis was 22.2% (6/27) and all underwent suprafascial revision. We performed one classical MACE by infrafascial approach as a salvage procedure. Overall reoperation rate was 25.8% and fecal continence was 89%. There were no reports of leakage through the stoma. Among patients who still used the stoma, 74% were satisfied with surgery and would strongly recommend the procedure to another patient. CONCLUSIONS: The MM procedure is a straightforward procedure, which can be performed in 15-20 min, avoids additional entero-entero anastomosis, precludes the use of the appendix, and has shown comparable results to either "classical" MACE or other LACE variants.

OBJECTIVE: Aphallia is a rare congenital abnormality with an incidence of 1 in 30 million births. In this video, we demonstrate implantation of a penile prosthesis in a neophallus performed 10 years previously in a patient aged 21. METHODS: Through a midline perineal incision aiming to reach the inferior surface of the pubic arch, we created a 16-cm tunnel for prosthesis insertion into the neophallus. We dressed the prosthesis with a polypropylene mesh to give stability to the component and avoid its extrusion. We anchored the lateral mesh to the inferior aspect of the pubic arch with 2.0 vicryl sutures in both sides. RESULTS: The patient had an excellent initial outcome, without any complaints of pain or other inflammatory findings. CONCLUSION: We acknowledge limited clinical experience with this technique. Further psychological evaluation will confirm if patients can have pleasant sexual experiences.

OBJECTIVE: Penile agenesis is a rare congenital abnormality with an incidence of 1 in 30 million births. We want to demonstrate in this video a new technique of neophalloplasty based on two transverse skin flaps from lower abdominal wall. METHODS: The patient was placed into a prone position; the urethral meatus was found inside the rectum, 2 cm from the anal border. An Anterior Sagittal Transrectal Approach (ASTRA) approach was performed; the urethra was isolated and repositioned as a perineal urethrostomy. We created the neophallus based on two flaps, each measuring 7 × 3 cm. After incision, flaps were rotated 90° and sutured to each other creating the neophallus. We also created a Mitrofanoff channel to secure bladder emptying in cases of urethrostomy stricture. RESULTS: The patient had an uneventful immediate postoperative evolution, but later showed some degree of penile retraction. He voids preferably through the urethrostomy and his mother uses the Mitrofanoff once a day. The current follow-up is 18 months. CONCLUSION: We acknowledge limited clinical experience with this technique. However, the same principle has been used to create catheterizable urinary channels, with favorable results and longer follow-up. The use of transverse skin flaps might be an interesting alternative for neophalloplasty in aphallia.

Ochoa syndrome is rare and its major clinical problems frequently unrecognized. We describe facial characteristics of six patients to help health professional recognize the inverted smile that these patients present and refer them to proper treatment. Patients’ medical records were reviewed and patients’ urological status clinically reassessed. At last evaluation patients’ mean age was 15.5 years, and age ranged from 12 to 32 years. Mean follow-up was 35 months (12 to 60). Initial symptoms were urinary tract infections in four patients (67%) associated with enuresis and incontinence in three of them (50%). One patient had only urinary tract infection and two lower urinary tract symptoms without infections. Initial treatment consisted of clean intermittent catheterization with anticholinergics for all patients. Four patients (67%) were submitted to bladder augmentation. Two patients had end-stage renal disease during follow-up, one received kidney transplantation and one patient remained on the waiting list for a renal transplantation. Familial consanguinity was present in only one case. This significant condition is rare, but it must be recognized by pediatricians, nephrologists and urologists in order to institute early aggressive urological treatment.
A síndrome de Ochoa é rara, e seus principais problemas clínicos são frequentemente não reconhecidos. Descrevem-se aqui características faciais de seis pacientes para auxiliar profissionais de saúde a reconhecer o sorriso invertido que eles apresentam e encaminhá-los para o tratamento adequado. Os prontuários médicos foram revisados e a condição urológica dos pacientes foi reavaliada clinicamente. A média de idade na última avaliação foi de 15,5 anos, variando de 12 a 32 anos. O seguimento médio foi de 35 meses (12 a 60). Os sintomas iniciais foram infecções do trato urinário em quatro pacientes (67%) associadas com enurese e incontinência urinária em três deles (50%). Um paciente apresentou infecções do trato urinário isoladamente e dois apresentaram sintomas do trato urinário inferior, porém sem infecções. O tratamento inicial consistiu em cateterismo intermitente limpo, com anticolinérgicos em todos os pacientes. Reconstrução urinária foi realizada em quatro pacientes (67%) por meio de ampliação vesical. Dois pacientes apresentaram doença renal em estágio terminal no seguimento, um recebeu transplante renal e outro manteve-se em lista de espera para transplante renal. Consanguinidade familiar esteve presente em apenas um caso. Essa condição significativa é rara, porém deve ser reconhecida por pediatras, nefrologistas e urologistas, a fim de instituir tratamento urológico agressivo precoce.

INTRODUCTION: Congenital adrenal hyperplasia (CAH) resulting from deficient 21-hydroxylase activity is an autosomal recessive disorder with an incidence of 1:5000-25,000 in Caucasian populations. Despite various techniques to treat CAH, total urogenital mobilization (TUM) has gained popularity. This technique has low morbidity, and can be performed by the perineal route with the patient in the dorsal lithotomy position without the need to separate the urethra from the vagina. We aim to demonstrate in this video the TUM technique step by step. METHODS: A 9-month-old child, born with ambiguous genitalia (Prader 3) with a 46XX karyotype and CAH diagnosis presented to our facility. Endoscopy showed a 2-cm common channel. RESULTS AND DISCUSSION: The patient was treated as described in the video and she had an uneventful clinical outcome with complete healing. TUM is an excellent alternative for treating CAH.

INTRODUCTION: Complete female epispadia (CFE) is a rare congenital anomaly occurring in 1 of 500,000 live births. The goals of CFE management include achieving continence, while protecting the kidneys, and creating functional, cosmetic external genitalia. PATIENT AND METHODS: We demonstrate in this video the steps of the surgery and present midterm follow-up of a 6-year-old child with CFE. RESULTS AND DISCUSSION: The patient had an excellent cosmetic result, and reported continence of 3 h period with mild leakage. The perineal infrapubic approach offers the possibility of restoring cosmesis and providing resistance in one surgery precluding the need for abdominal bladder neck surgery.

AIMS: To report our data on initial urological presentation after in utero myelomeningocele (MMC) closure. METHODS: A prospective urological assessment at first presentation was designed for patients that had undergone in utero MMC closure and referred to our urological facility. The protocol consisted of detailed medical history, renal sonography, voiding cystourethrogram, and urodynamic evaluation. RESULTS: In utero MMC closure was performed in 19 patients at gestational age of 25.6 weeks 25-27. Birth occurred at a mean gestational age of 31.8 weeks 26-36. Hyperactive bladder was observed in 89.5% 17/19. Bladder compliance was normal in two cases (10.5%), was markedly reduced in 10 patients (52.6%) and not possible to be determined due to urinary leakage in 7 patients (36.8%). We observed normal bladder capacity in 8 patients (42.1%), reduced in 11 (57.9%), and detrusor-sphincter dyssynergia in 9 patients (47.4%). Underactive bladder was diagnosed in one case. Clean Intermittent Catheterization was initiated by 11 patients (57.9%) mostly in association with anticholinergics 10/11. Vesicoureteral reflux was found in 5 patients (26.3%) and 9 had pyelonephritis at a mean follow-up of 5.4 months 2-17. CONCLUSIONS: Our data suggested that despite in utero MMC surgery, patients are at risk for bladder abnormal function and renal deterioration and should be aggressively treated, not differently from those operated in the post-natal term. This study has the merit of being a prospectively set evaluation performed by one investigator, including the urodynamic study. We acknowledge the need of long-term follow up.

AIMS: To assess whether crossing rectus abdominis muscle strips, as proposed by Yachia, would change urinary catheterizable conduit's pressure profilometry, in static and dynamic conditions. METHODS: Non-randomized selection of 20 continent patients that underwent Macedo's ileum-based reservoir, 10 including Yachia's technique (Study Group) and 10 without this mechanism of continence (Control Group). Demographics and cystometric data were assessed. Conduit's pressure profilometry was obtained by infusing saline through a multichannel catheter, at rest and during Valsalva maneuver. We assessed the pressure: (a) in the bladder; (b) in conduit's proximal segment; and (c) in conduit's distal segment, which is presumably the abdominal wall and crossed muscle strips site. RESULTS: Mean age at surgery was 6.1 years in the Control Group and 7.7 years in the Study Group. There was no statistically significant difference between groups regarding maximum cystometric bladder capacity and leakage point pressure. At rest, the pressure profilometry showed similar results between groups in all segments analyzed. During Valsalva maneuver, pressure profilometry showed similar results between groups in bladder and conduit's proximal segment pressure. In this condition, conduit's distal segment pressure in the Study Group (Mean = 72.9 and Peak = 128.7 cmH2 O) was significantly greater (P < 0.05) than conduit's distal segment pressure in the Control Group (Mean = 48.3 and Peak = 65.1 cmH2 O). CONCLUSIONS: Crossing muscle strips over the conduit significantly increases the pressure in its distal segment during contraction of the rectus abdominis muscle, which can be important in moments of sudden increase in abdominal pressure in order to keep continence.

Introduction Cloacal exstrophy is a rare occurrence with an incidence of 1:200,000 to 1:400,000 live births. It represents one of the most challenging reconstructive endeavors faced by pediatric surgeons and urologists. Aside from the genitourinary defects, there are other associated anomalies of the gastrointestinal, musculoskeletal and neurological systems that require a multidisciplinary approach when counseling anxious parents. Material and Methods We present a video of a patient with cloacal exstrophy treated with 21 days of life. Surgery consisted of separation and tubularization of the cecal plate from the exstrophied bladder halves and colostomy construction. The bladder was closed primarily and umbilical scar reconstructed and used for ureteral and cistostomy drainage. A urethral catheter was used to guide bladder neck tubularization. A final epispadic penis was obtained and planned for further repair in a second step. Results The patient had an initial uneventful postoperative course and immediate outcome was excellent. The bladder healed nicely but patient presented with abdominal distension in the 5th day of postoperative setting requiring parenteral nutrition. The distal colon persisted with lower diameter although non obstructive, but causing difficulty for fecal progression. Continuous colostomy dilatation and irrigation were required. Conclusions Approximating the bladder halves in the midline at birth and primary bladder closure is a viable option, intestinal transit may be a issue of concern in the early postoperative follow-up. .

Purpose To compare the histological characteristics of keratinized versus non-keratinized onlay island flaps in an experimental rabbit model. Materials and Methods Sixteen male rabbits were randomly allocated into two experimental groups: keratinized and non-keratinized onlay island flaps. A defect was created in the ventral aspect of the penile urethra. In the keratinized group, a longitudinal island flap was harvested from the external prepuce and rotated to cover the urethral defect. In the non-keratinized group a transverse island flap was harvested from the inner prepuce. The animals were sacrificed after 2, 4, 8 and 12 weeks. Results The flaps were viable in all animals, and no deaths were associated with the procedure. Two urethrocutaneous fistulas were identified, one in each experimental group. A similar pattern of fibrosis was identified in both groups. The keratinized epithelium of the external prepuce kept its histological aspect and keratin production. Both keratinized and non-keratinized groups presented a slight decrease on the epithelial thickness, however without a statistically significant difference between groups. Conclusions In this short-term rabbit model, we observed that the stratified squamous keratinized epithelium from the external prepuce kept its keratin production. There was no statistical influence of the flap type on the mean epithelial thickness. .

OBJECTIVE: To use anthropometric measurements to compare nutritional status in children with neurogenic bladder dysfunction secondary to meningomyelocele who underwent enterocystoplasty and those who did not undergo surgery. METHODS: A case-control study was conducted in 20 children, divided into two groups: those who had enterocystoplasty (Group A) and those who did not undergo surgery (Group B), matched for genre and age. Weight, height, arm circumference, and triceps skinfold thickness were the parameters used. Nutritional assessment was determined by calculating the indexes, based on age and genre. Classification was based on the percentile and the results were compared with the reference values. RESULTS: The mean age was 6.41 years in Group A and 6.35 years in Group B. The interval between surgery and evaluation was 11 months. The following measures were found for Group A: 80% of children were eutrophic, a percentage 30% greater than that in Group B; arm muscle circumference was adequate in 40% of patients, a percentage 20% greater than that in Group B; arm muscle area was adequate in 90%, a percentage 30% greater than that in Group B. Values in Group B were as follows: for triceps skinfold thickness, 60% of patients had values above the mean, a percentage 20% greater than that in Group A; for arm fat index, 60% of patients were above the mean value, 40% greater than in Group A. CONCLUSION: Patients who had undergone enterocystoplasty showed better nutritional status, while the control group presented higher fat indexes in anthropometric measures. However, the differences between groups were not statistically significant.

OBJECTIVE: This study was designed to evaluate the effect of testosterone replacement on the fibrotic process of the detrusor bladder muscle during the normal aging process. METHODS: 15 Wistar senile rats, aged between 18 and 20 months were divided into two groups: testosterone group - 11 animals submitted to the administration of testosterone undecanoate (50 mg/kg intramuscular), once per month; and, Control group - four animals underwent a sham procedure. At the end of eight weeks, animals from both groups were sacrificed; bladders were removed and subsequently stereologically evaluated to determine the volumetric density of collagen fibers. The success of testosterone administration was confirmed by the measurement of serum testosterone at the beginning and end of the experiment. RESULTS: In the replacement group, testosterone average was 3.2 ng/ml, whereas in the control group, the mean testosterone at the end of the experiment was 0.64 ng/ml (p < 0.05). Analysis of stereological collagenous fiber showed higher density in the control group compared to the testosterone group I (56% versus 37.02%, respectively). The difference of volume concentration of collagen between both groups was statistically significant (p < 0.000). CONCLUSION: Bladder wall fibrosis was reduced in senile rats subjected to testosterone replacement.

OBJECTIVE: To demonstrate ventral corporoplasty, with tunica vaginalis flap to reconstruct the corpora cavernosa, in a two-stage strategy for proximal hypospadias surgery. METHODS: Assessment of residual curvature after complete urethral plate division and transverse superficial cuts in albuginea. Ventral incision of tunica albuginea to elongate the ventral surface of the penis and use of a tunica vaginalis flap to reconstruct the defect in corpora cavernosa. Dorsal preputial island flap was used to cover the penile ventral surface, to be tubularized in a second stage, together with the original urethral plate. RESULTS: Patient had an uneventful follow-up. Penile aspect was very satisfactory with no residual curvature. CONCLUSION: Tunica vaginalis is an attractive alternative for ventral corporoplasty in hypospadia repair and has the advantages of prompt disposability, autologous use, and does not represent an extra cost for treatment.

OBJETIVO: Utilizar as medidas antropométricas para comparar o estado nutricional em crianças com bexiga neurogênica secundária à mielomeningocele submetidas a enterocistoplastia àquelas não submetidas à cirurgia. MÉTODOS: Estudo tipo caso-controle conduzido em 20 crianças, divididas em dois grupos, aquelas que realizaram enterocistoplastia (Grupo A) versus crianças não operadas (Grupo B), pareados por gênero e idade. Os parâmetros utilizados foram peso, altura, circunferência do braço e prega cutânea triciptal. A avaliação nutricional foi determinada calculando-se índices baseados na idade e no gênero. A classificação foi baseada em porcentagens, e os resultados foram comparados com valores de referência. RESULTADOS: A média da idade foi 6,41 anos no Grupo A e de 6,35 no Grupo B. O intervalo entre a cirurgia e a avaliação foi de 11 meses. As seguintes medidas foram encontradas para o Grupo A: 80% das crianças eram eutróficas, 30% maior do que no Grupo B; circunferência braquial foi adequada em 40% dos pacientes, 20% maior do que no Grupo B; a área do músculo do braço foi adequada em 90%, 30% maior do que no Grupo B. Os valores no Grupo B foram os seguintes: 60% apresentaram prega cutânea triciptal acima do valor médio, uma porcentagem 20% acima do que no Grupo A; para índice de gordura braquial, 60% dos pacientes estavam acima da média, 40% maior do que no Grupo A. CONCLUSÃO: Pacientes submetidos à enterocistoplastia demonstraram melhor estado nutricional enquanto o grupo controle apresentou índices de gordura mais elevados nas medidas antropométricas. Entretanto, a diferença entre os grupos não foi estatisticamente significativa.

OBJECTIVE: To evaluate in a rabbit experimental model a mechanism of continence of catheterizable urinary conduits (CUC), focusing on the behavior of intersected rectal muscle fibers in relation to the channel by histological and histochemical analysis, and secondarily to register conduit continence rates from clinical and urodynamic data. MATERIALS AND METHODS: 12 rabbits were submitted to construction of a CUC from two abdominal skin flaps and divided into two groups: 8 with a urinary neo-sphincter created according to Yachia and 4 controls. We registered clinical outcome, urodynamic studies and microscopic analysis of CUC on the surface of the conduit, which was in direct contact with the mechanism of continence. We took muscle samples from the mechanisms of continence and performed histochemical evaluation by enzymatic reactions. RESULTS: Histological evaluation of the CUC showed no difference between groups. Histology and immunohistochemistry of the muscle fibers showed that areas of necrosis, cell atrophy and motor neuron injury from the first eight weeks recovered by the end of 16th week. Conduit complications occurred in 4 animals (33%). The average detrusor leakage point pressure through the conduit was 90 cm H2O versus 39 cm H2O through the urethra. CONCLUSION: The mechanism of continence did not promote ischemic stress on the conduit, was able to promote high pressure resistance and showed good recovery of intersected muscle fibers, after an initial slight atrophy, suggesting good durability of the neo-sphincter.

OBJECTIVE: The total urogenital mobilization (TUM) technique avoids dissection of the vagina from the urinary tract. However, in the case of a long common channel, bowel interposition for vaginal replacement may be necessary. We present a video of the TUM technique in cloacal repair with ileal neovaginoplasty. METHODS: An 8-month-old female patient with cloaca, presenting a 4-cm common channel, was operated on by the TUM technique, through a perineal sagittal with additional abdominal approach. She had undergone decompressing colostomy at birth. Total urogenital sinus mobilization was performed with ileal neovaginoplasty. RESULTS: The patient had a good postoperative outcome, an endoscopy of all structures reconstructed was performed at PO day 30, and home dilatation of colon and vagina by parents was initiated. CONCLUSION: TUM with neovaginoplasty bowel interposition is an effective technique for repairing long common channels.
