Prevalence of chronic endometritis in infertile women undergoing hysteroscopy and its association with intrauterine abnormalities: A Cross-Sectional study.

OBJECTIVE: Chronic endometritis (CE) is an inflammatory condition with several different risk factors. We aimed to examine whether intrauterine abnormalities, such as endometrial polyps, submucosal myomas, intrauterine adhesions, or a septate uterus, were associated with an increased likelihood of developing chronic endometritis. METHODS: A cross-sectional study was conducted on 335 infertile women who underwent hysteroscopy surgery at the Ayatollah Taleghani Hospital Infertility Center, affiliated by Shahid Beheshti University of Medical Sciences, in 2022. All participants in the study underwent hysteroscopic surgery, which allowed for direct visualization of the intrauterine cavity, and endometrial biopsies were taken for further analysis. To characterize endometritis, plasma cell infiltration was assessed. Patients with ≥5 plasma cells observed in 10 high-power fields were defined as having chronic endometritis. RESULTS: Endometritis was observed in 51.3% of the patients, totaling 172 individuals. Logistic regression analysis revealed that patients with endometrial polyps had 5.2 times higher odds of developing endometritis compared to patients without polyps (95% CI = 2.9, 9.2) (p-value <0.001). Similarly, patients with intrauterine adhesions had a significant increase in the odds of endometritis (OR = 4.6, 95% CI = 2.1, 10.1) (p-value <0.001). CONCLUSIONS: Treatment or removal of endometrial abnormalities through hysteroscopic procedures may help to reduce the risk of chronic endometritis and improve fertility outcomes. Further research is necessary.

Definition, prevalence, clinical relevance and treatment of T-shaped uterus: systematic review.

OBJECTIVES: To summarize in a systematic review the current evidence regarding definitions, diagnosis, prevalence, etiology, clinical relevance and impact of surgical treatment for T-shaped uterus not related to diethylstilbestrol (DES) exposure, and to highlight areas on which future research should focus. METHODS: A search of PubMed, Scopus and EMBASE was performed on 9 April 2020 using the search terms 't-shaped OR t-shape OR infantile OR (lateral indentation) OR (diethylstilbestrol OR DES) AND (uterus OR uterine OR uteri) AND (anomaly OR anomalies OR malformation OR malformations)'. Additionally, the reference lists of the included studies were searched manually for other relevant publications. All studies presenting data on T-shaped uterus not associated with DES exposure and including at least 10 women were considered eligible. Studies regarding DES-related T-shaped uterus were excluded because DES has not been used since 1971. There were no restrictions on language, date of publication or status of publication. RESULTS: Of 2504 records identified by the electronic search, 20 studies were included in the systematic review. The majority of studies were of poor quality. In 11 of 16 studies reporting on the diagnosis of T-shaped uterus, the diagnostic method used was three-dimensional ultrasound. There is no consensus on the definition of T-shaped uterus, but the most cited criteria (4/16 studies) were of the European Society of Human Reproduction and Embryology and the European Society for Gynaecological Endoscopy (ESHRE/ESGE; 2013). The prevalence of T-shaped uterus varied from 0.2% to 10% in the four included studies reporting such data. With respect to etiology (except for DES), T-shaped uterus was considered a primary condition in three studies and secondary to adhesions in five and adenomyosis in one. T-shaped uterus was related to worse reproductive outcome based on subfertility (nine studies), miscarriage (seven studies), preterm delivery (two studies), ectopic pregnancy (one study) and repeat implantation failure (seven studies). Of the 12 studies that reported on the effects of surgical treatment of T-shaped uterus by hysteroscopic metroplasty, some mentioned an improvement in pregnancy rate (rates ranging from 49.6% to 88%; eight studies), live-birth rate (rates ranging from 35.1% to 76%; seven studies) and term-delivery rate (four studies) and a reduction in miscarriage (rates ranging from 7% to 49.6%; five studies) and ectopic pregnancy (one study). However, the evidence is of very low quality with serious/critical risk of bias toward overestimating the intervention effect. Some authors reported no complications related to the procedure, while others mentioned persistence of the dysmorphism (rates ranging from 1.4% to 11%; three studies), bleeding (1.3%; one study), infection (2.6%; one study) and adhesions (11.1% and 16.8%; two studies). CONCLUSIONS: The prevalence, etiology and clinical relevance, with respect to reproductive outcome, of T-shaped uterus remain unclear and there is no consensus on the definition and diagnostic method for this condition. Expectant management should be considered the most appropriate choice for everyday practice until randomized controlled trials show a benefit of intervention. © 2020 International Society of Ultrasound in Obstetrics and Gynecology.

Nefrectomia en la edad pediátrica con técnica de cirugia minimamente invasiva: abordaje retroperitoneal como estándar de oro para el paciente sin o con enfermedad renal crónica (premio dr. efrain vargas año 2014) / Nephrectomy in pediatric age with minimally invasive surgery technique: retroperitoneal approach as a gold standard for patients without or with chronic kidney disease (Dr. Efrain Vargas Award 2014)

Two successful spontaneous pregnancies, single and twin, in uterus bicornis unicollis after deep infiltration endometriosis surgery.

A 26-year-old patient was admitted in our center with one year of infertility history after a miscarriage. She was diagnosed with uterus bicornis unicollis and deep infiltrating endometriosis (DIE); therefore, she underwent endometriosis focus removal surgery. After six-months, she conceived spontaneously and delivered one healthy baby. One year after the first pregnancy delivery, she conceived spontaneously and delivered twins in an extremely rare condition of uterus bicornis unicollis, of which there are only 15 cases reported worldwide. Both pregnancies were monitored every two or three weeks using ultrasonography to assess fetal growth, and cervical length was measured to assess the risk of premature delivery.

Incidental Discovery of Adenocarcinoma of an Augmented Bladder in a Patient With Myelomenigocele Undergoing Cystolithotomy.

Bladder malignancy in patients with congenital bladder anomalies who have undergone bladder augmentation is a rare but well-recognized condition. These patients present with locally advanced or metastatic disease and have poor survival. We report a case of a patient with myelomeningocele who was incidentally found to have a high-grade intestinal type adenocarcinoma of her bladder augment at the time of cystolithotomy. This case highlights the need to continue to follow patients with congenital bladder anomalies and highlights the lack of adequate screening methods available.

Y-type urethral duplication with rectal implantation of the urethra: Which is the best approach?

INTRODUCTION: Y-type urethral duplication describes the condition in which a functional urethra is implanted in the rectum, and there is also a dysplastic topic urethra which produces mostly urinary dribbling. These patients are at risk of urinary tract complications and UTI. We aimed to present the surgical steps of a case treated by ASTRA approach in which we separated the urethra from the rectum and created a perineal urethrostomy. MATERIAL AND METHODS: We treated a 5-month-old boy with Y-type (IIA-2) urethral duplication, in whom the orthotopic urethra was patent just in the penile segment. The patient had urinary flow per anus and minimal dribbling through the orthotopic urethra. We performed a combined cystoscopy with retrograde urethrogram and managed to catheterize the dysplastic urethra with a guide-wire that showed ectopic implantation in the prostatic urethra, below the bladder neck. We performed an ASTRA procedure to separate the urethra from the rectum. The urethral stump was further mobilized to the perineum and anastomosed to a perineal skin flap to create a stoma and minimize the risk of stricture. RESULTS: The patient was followed at 2 month-intervals, and at 6 months follow-up had an excellent outcome. CONCLUSION: The ASTRA approach proved to be an excellent alternative for Y-type urethral duplication with functional urethra implanted in the rectum. We believe that further efforts to reconstruct the urethra should be avoided, with a better and simpler option being to create a definitive perineal urethrostomy.

Clinical Outcomes of the Upper Urinary Tract after Ureteral Clipping for Treatment of Low Functioning or Nonfunctioning Renal Moieties.

PURPOSE: A growing body of evidence suggests that it is safe to ligate the ureter of poorly functioning renal moieties during renal transplantation. We present clinical outcomes and data on hydronephrosis progression in pediatric cases associated with ectopic ureters and obstructive ureteroceles. MATERIALS AND METHODS: We prospectively collected data for 35 consecutive patients (23 females and 12 males) who underwent ureteral clipping between February 2011 and August 2016. Patients were divided into 4 groups consisting of 1) duplex system with ectopic ureter (45.7%), 2) duplex system with a large ureterocele (11.4%), 3) other duplex system (8.6%) and 4) single system kidneys (34.3%). Patients were followed for clinical outcomes and hydronephrosis trends. Comparisons included preoperative and postoperative anteroposterior diameter, maximal ureteral diameter and ureterocele size. RESULTS: Median age at surgery was 59 months (IQR 11 to 120, range 5 to 216). Median ± SD operative time was 108.9 ± 31.1 minutes (range 20 to 180) and median length of stay was 7.5 hours (IQR 6 to 19, range 5 to 336). Immediate resolution of urinary incontinence was observed in all 16 ectopic ureter cases. After a median ± SD followup of 20.8 ± 13.8 months (IQR 8.5 to 30, range 6 to 50) 97.2% of the patients remained asymptomatic. No significant differences were observed between initial and last anteroposterior diameter measurements except in group 1 (p = 0.001). All ureteroceles demonstrated a significant decrease in median ± SD size after clipping (from 2.7 ± 0.41 to 0.53 ± 0.92 cm, p = 0.003). Pyonephrosis developed in 1 patient, who underwent laparoscopic nephrectomy. CONCLUSIONS: Ureteral clipping appears to be a reasonable, safe and effective option for pediatric patients in the reported settings, with the potential to be simpler and quicker than extirpative or reconstructive procedures.

Aplasia uterina total em cadela com atrofia segmentar de vagina / Total uterine aplasia in bitch with segmental atrophy of vagina

Background: Congenital uterine malformations are rarely identified in domestic and human animals and are related to problems during the embryonic formation of the paramesonephric ducts. Cases of agenesis and segmental aplasia or unicorn uterus have been described in bitches, but there are no reports of total uterine aplasia in this specie. The report of a case of total uterine aplasia and segmental atrophy of the cranial vagina, accidentally diagnosed is reported herein.Case: An adult female bitch without defined breed in bad general condition was attended in the emergency service in a Veterinary Hospital. During anamnesis the information was restricted because it was an errant animal rescued for the consultation, but accompanied for at least 12 months in the environment in which it lived. Data related to the estrous cycle were unknown, but no gestation was observed in the last year. Investigations detected anemia and intense thrombocytopenia, azotemia and increased alanine aminotransferase. Two days later, with no progression, images suggestive of hemometra/ mucometra were observed during abdominal ultrasonography, and the patient underwent emergency ovariohysterectomy despite the general poor condition. Before the procedure the uterus was not routinely identified, but a fibromuscular, nontubular and thin structure occupied the region corresponding to the horns and uterine body, thickening in the cervix region. Death four days after surgery and sent to necropsy. During necropsy it was observed that the vulva and the vestibule of the vagina did not present macroscopic alterations, however there was a marked digitiform narrowing of the cranial region of the vagina, which ended in blind bottom. The mucosa in this narrowing was smooth, without folds. The microscopic structure of the ovaries, uterine tubes and caudal vagina were preserved.[...](AU)

Síndrome de Hemivagina Obstruida, Útero Didelfo y Agenesia Renal Ipsilateral (OVHIRA), Drenado Parcialmente por Fístula Útero-Uterina Espontánea / Obstructed Hemivagina Syndrome, Uterus didelphys and Ipsilateral Renal Agenesis (OVHIRA), Partially Drained by Spontaneous Uterine-Uterine Fistula

RESUMEN Antecedentes: El síndrome de hemivagina obstruida, útero didlefo y anomalía renal ipsilateral (OVHIRA) es una malformación mülleriana infrecuente. Objetivo: Se presenta un caso con una complicación no antes descrita y se hace una revisión de la literatura hasta la fecha. Caso clínico: Mujer de 12 años de edad con antecedentes de diagnóstico de útero bicorne y agenesia renal derecha en la infancia. Veintidós meses post menarquia consulta por algia pelviana y dismenorrea premenstrual. Ecografía revela hematómetra en cuerpo uterino izquierdo, de 142 x 69 x 61 mm. Resonancia nuclear magnética (RNM) describe además un hematocolpos de 7 x 10 cm y un tabique vaginal transverso de hemivagina izquierda. Se diagnostica OHVIRA y se planifica cirugía para resecar el tabique. Días antes del la cirugía, la paciente tiene episodio de metrorragia. Ecográficamente se constata una disminución considerable del volumen de hematómetra. En la cirugía se pesquisa fístula uterina que comunica útero obstruido izquierdo con útero no obstruido derecho por donde había drenado espontáneamente la hematómetra. Al resecar el tabique vaginal izquierdo se termina de drenar hematómetra y hematocolpos. Al alta, paciente se maneja con dilatación vaginal progresiva por seis meses para evitar la estenosis del tabique. Conclusión: Se presenta una complicación no descrita, fístula útero uterina, de una malformación mülleriana infrecuente (OVHIRA). El proceso diagnóstico meticuloso, la cirugía bien planificada y la dilatación vaginal prolongada permitieron tener éxito en su manejo.

ABSTRACT Background: Obstructed Hemivagina and Ipsilateral Renal Anomaly Syndrome (OHVIRA) is an uncommon Müllerian anomaly. Objective: A case is described and the main complications related to the syndrome are reviewed. Case report: Female, 12 years old, with a medical history of a bicornuate uterus and right renal agenesis diagnosed at birth. Twenty-two months post menarche she seeks medical attention due to pelvic pain, menometrorrhagia and premenstrual dysmenorrhea. An ultrasound revealed a hematometra, of 142 x 69 x 61 mm, in the left uterus. Magnetic resonance imaging also described a 7 x 10 cm hematocolpos and a transverse vaginal septum of the left hemivagina. OHVIRA is diagnosed and surgery is planned to resect the septum. Two days before the surgery, the patient has an episode of abundant metrorrhagia. Ultrasonographically a considerable decrease in the volume of the hematometra is observed. In surgery, a uterine fistula is discovered which communicates the left obstructed uterus with the right unobstructed uterus, where the hematometra had been partially drained. During the procedure, the left vaginal septum is resected, which completes the drainage of the hematometra and hematocolpos. At discharge, the patient undergoes progressive vaginal dilation for six months to avoid stenosis of the septum. Conclusion: An utero-uterine fistula has not been previously described as a complication of OHVIRA. The meticulous diagnostic process, the well planned surgery and the prolonged vaginal dilation allowed for a successful management.

Tratamiento quirúrgico conservador en paciente monorrenal con esclerosis tuberosa y angiomiolipoma complicado: presentación de caso y revisión bibliográfica / Conservative surgical treatment in monorrenal patient with sclerosis and complicated tuberous angiomyolipom: case report and literature review

Los angiomiolipomas renales son formaciones renales que se presentan de forma aislada o asociadas con otras patologías como esclerosis tuberosa o enfermedad de Von Hippel Lindau. Los angiomiolipomas renales se pueden presentar clínicamente con un shock hipovolémico por lesión de uno de sus vasos o con dolor abdominal por efecto masa debido a su tamaño. La resolución de los angiomiolipomas puede ser de manera programada o de urgencia, siendo las vías elegidas la nefrectomía parcial o la embolización arterial selectiva, dependiendo siempre de los recursos que se tengan y la experiencia del equipo quirúrgico.

Renal angiomyolipomas are kidney formations presented in isolation or associated with other diseases such as tuberous sclerosis or Von Hippel Lindau disease. Renal angiomyolipoma may present clinically with hypovolemic shock due to injury of one of its vessels or with abdominal pain due to mass effect because of its size. Angiomyolipomas can be resolved on scheduled basis or emergency, where the chosen ways are partial nephrectomy or selective arterial embolization, always depending on the resources you count on and the experience of the surgical team.

Trajectories and Predictors of Allograft Dysfunction after Renal Transplantation in Children.

BACKGROUND: The survival rates of renal transplant children are indeed on the rise, but it is still important to ensure that there is optimal renal function in these children in all their future growing years. The number of functioning nephrons and the graft ability to adapt to an increasing demand during body growth seem to be the most important factors for long-term allograft function. This study examined the long-term change in the glomerular filtration rate in a pediatric kidney transplant cohort and the importance of the recipient and donor ages in predicting transplant outcome. METHODS: Data on 67 renal transplant children who underwent 278 inulin-clearance measurements between 2000 and 2010 were examined. A longitudinal latent class model was used to identify renal function trajectories and classify the children. RESULTS: This model identified 3 trajectories of renal allograft function after pediatric kidney transplantation: 'low and decreasing', 'moderate and stable', and 'high and sharply decreasing'. The probability of belonging to the low and decreasing trajectory - that is, the poorer outcome - was lower in recipients of grafts from living versus deceased donor (adjusted OR (aOR) 0.02; p = 0.03). This probability increased with recipient age (aOR 1.20 per year of recipient ageing; p = 0.07) and donor-recipient age-difference (aOR 1.13 per additional year; p = 0.07). CONCLUSION: This study suggests that donation from living donors and from younger donors are favorable factors for long-term allograft function.

A wet dressing for male genital surgery: A phase II clinical trial

ABSTRACT Purpose: This study was to confirm the safety and efficacy of BC dressing when used in surgical male wound healing at the urogenital area. Methods: Open, non-controlled clinical study of phase II. A total of 141 patients, among those children, adolescents and adults with hypospadias (112), epispadias (04), phymosis (13) and Peyronie's disease (12) that had a BC dressing applied over the operated area after surgery. A written informed consent was obtained from all participants. Study exclusion criteria were patients with other alternative treatment indications due to the severity, extent of the injury or the underlying disease. The outcomes evaluated were efficacy, safe and complete healing. The costs were discussed. Results: In 68% patients, the BC dressing fell off spontaneously. The BC was removed without complications in 13% of patients at the outpatient clinic during the follow-up visit and 17% not reported the time of removal. In 3% of the cases, the dressing fell off early. Complete healing was observed between 8th and 10th days after surgery. The BC dressings have shown a good tolerance by all the patients and there were no reports of serious adverse events. Conclusion: The bacterial cellulose dressings have shown efficacy, safety and that can be considered as a satisfactory alternative for postoperative wound healing in urogenital area and with low cost.

Signs and symptoms of developmental abnormalities of the genitourinary tract / Sinais e sintomas das anormalidades do desenvolvimento do trato geniturinário

Abstract Objective: The abnormalities of the genitourinary tract development are the leading cause of chronic kidney disease (CKD) in children. The diagnosis of this disease in Brazil is late and incomplete, which results in increased morbidity and mortality in this age group. Early diagnosis of this condition is the prerogative of generalist pediatricians, and the aim of this study was to review the clinical signs and symptoms associated with developmental abnormalities of the genitourinary tract. Data sources: Based on the description of a symbolic clinical case, the authors conducted a non-systematic review of medical literature. Data synthesis: The results suggest that the following data should be used as a warning for early diagnosis of affected children: (a) combined urinary tract abnormalities (chromosomal abnormalities; sequence of malformations [VACTERLand Prune-Belly]; and musculoskeletal, digestive tract, heart, and nervous system malformations); (b) previous history (congenital anomalies of the kidney and urinary tract [CAKUT] in the family, low birth weight, and oligoamnios); (c) clinical signs (polyuria/nocturia, urinary tract infection, systemic arterial hypertension, failure to thrive, weak urinary stream, difficulty to start urination, distended bladder, non-monosymptomatic enuresis, urinary/urge incontinence, and bowel and bladder dysfunction); and (d) pre- and postnatal ultrasonographic alterations (increased anteroposterior diameter of the renal pelvis, mainly in the third trimester of pregnancy; single kidney; hydronephrosis associated with other abnormalities; and hydronephrosis with parenchymal involvement in the post-neonatal assessment). Conclusion: The suggestions shown here can help the pediatrician to establish clinical hypotheses for the early diagnosis of developmental abnormalities of the genitourinary tract without resorting to expensive and invasive procedures.

Resumo Objetivo: As anormalidades do desenvolvimento do trato geniturinário são a principal causa de doença renal crônica (DRC) em crianças. O diagnóstico dessa doença no Brasil é formulado de maneira incompleta e tardia, o que resulta em aumento na morbimortalidade nessa faixa etária. O diagnóstico precoce dessa condição é prerrogativa dos pediatras generalistas e o objetivo deste trabalho foi revisar os sinais e sintomas clínicos associados às anormalidades do desenvolvimento do trato geniturinário. Fontes dos dados: A partir da descrição de um caso clínico simbólico, fizemos uma revisão não sistemática da literatura médica. Síntese dos dados: Os resultados sugerem que os seguintes dados devem ser usados como alerta para o diagnóstico precoce das crianças acometidas: a) anomalias do trato urinário compostas (anomalias cromossômicas, sequências de malformações – Vacterl e Prune-Belly, malformações musculoesqueléticas, do trato digestivo, cardíacas e do sistema nervoso); b) antecedentes (anomalias congênitas do rim e trato urinário (CAKUT) na família, baixo peso ao nascer e oligoâmnio); c) sinais clínicos (polaciúria/noctúria, infecção urinária, hipertensão arterial sistêmica, baixo ganho de peso, jato urinário fraco, dificuldade para iniciar a micção, bexigoma, enurese não monossintomática, urge/incontinência urinária, disfunção do intestino e da bexiga) e d) alterações ultrassonográficas ante e pós-natais (diâmetro anteroposterior da pélvis renal aumentado principalmente no terceiro trimestre da gestação, rim único, hidronefrose associada a outras anomalias e hidronefrose com comprometimento de parênquima na avaliação pós-neonatal). Conclusão: As sugestões apresentadas podem ajudar o pediatra a estabelecer hipóteses clínicas para o diagnóstico precoce das anormalidades do desenvolvimento do trato geniturinário sem metodologias caras e invasivas.

[Latex sensitization prevalence through prick test in patients with genitourinary malformations and more than 3 surgeries]. / Prevalencia de sensibilización al látex mediante prueba cutánea (prick test) en pacientes con malformaciones genitourinarias con más de tres intervenciones quirúrgicas.

BACKGROUND: Latex allergy is a public health issue. It presents elevated prevalence in known risk groups, especially in those patients with spine bifida condition, urinal malformation and for those with orthopedic problems - multiple surgeries. Health Services in Mexico do not have the enough studies about prevalence and risk associated to latex allergy. OBJECTIVE: Determine latex sensitization prevalence through PRICK test in patients with genitourinary malformations and more than 3 surgeries in UMAE pediatric CMNO unit, considering too related factors. MATERIAL AND METHOD: An analytical and descriptive cross-sectional study was performed, which included men and women from 1 to 16 years with genitourinary malformations and more than three surgeries performed. A survey to know the risk factors associated and skin puncture test was performed with latex extract, with positive and negative control. Serum levels of total IgE and eosinophils were measured in peripheral blood. RESULTS: The study exposed prevalence of 30.72%. Related to associated factors as follows: atopy (p=0.047), previous antecedent reaction to latex products (p=0.003) specific for balloons (p=0.000) and gloves (p=0.002). There was not association related to amount of surgeries and surgical interventions on early age, either for high levels of total serum IgE. CONCLUSION: Prevalence to latex sensitization is high in risk groups. Especially in those with atopy thereby is important for health personal to identify these patients in order to implement on time the preventive primary/secondary measures. With these actions potential mortal risks like anaphylaxis will be avoided. This will decrease sanitary costs and mortality.

Antecedentes: la alergia al látex tiene alta prevalencia en grupos de riesgo conocidos, especialmente en pacientes con espina bífida, malformaciones urinarias y ortopédicas con múltiples cirugías. En México no se cuenta con suficientes estudios que reporten la prevalencia y factores de riesgo asociados. Objetivo: determinar la prevalencia de sensibilización al látex mediante prueba de prick con extracto de látex en pacientes con malformaciones genitourinarias y más de tres cirugías en la Unidad Médica de Alta Especialidad de Pediatría del Centro Médico Nacional de Occidente, así como los factores asociados. Material y método: Se realizó un estudio transversal analítico y descriptivo, que incluyó hombres y mujeres de 1 a 16 años, con malformaciones genitourinarias y más de tres cirugías. Se aplicó una encuesta para conocer los factores de riesgo asociados y se realizó prueba cutánea por punción con extracto de látex, con control positivo y negativo. Se midieron niveles séricos de IgE total y eosinófilos en sangre periférica. Resultados: la prevalencia encontrada fue de 30.7% y los factores de riesgo asociados: atopia personal (p=0.047), antecedente de reacción previa con productos con látex (p=0.003), específicamente con globos (p=0.000) y guantes (p=0.002). No hubo asociación entre el número de cirugías e intervenciones quirúrgicas a edades tempranas, tampoco con concentraciones elevadas de IgE sérica total. Tuvieron reacción cruzada a frutas-látex 25% de los pacientes, los alimentos asociados fueron: aguacate, papaya, fresa y kiwi. Conclusión: la prevalencia de sensibilización al látex es alta en los grupos de riesgo, sobre todo con antecedente de atopia, por lo que es importante que el personal de salud identifique a estos pacientes a fin de implementar oportunamente las medidas de prevención primaria y secundaria; evitar efectos severos potencialmente mortales, como la anafilaxia, para disminuir la morbilidad y la mortalidad y los costos sanitarios.

In this issue are described different possible etiologies of vaginal absence, like congenital abnormalities or acquired ones. In this regard, therapeutic methods vary widely, which indicates that ideal results have yet to be obtained.(AU)

Minirressectoscópio de Gubbini / Miniresectoscope of Gubbini

Os instrumentos empregados na histeroscopia cirúrgica experimentaram grandes avanços nos últimos 30 anos e permitiram escolher desde ressectoscópios de 26 e 21 Fr. acoplados a corrente mono ou bipolar até a office hysteroscopy, que contempla o uso de sistemas operatórios de diâmetros semelhantes àqueles empregados na histeroscopia diagnóstica. Essas opções ampliaram e fortaleceram as possibilidades de indicação cirúrgicas, minimizaram riscos e reduziram acentuadamente as contra indicações. A introdução do minirressectoscópio de Gubbini de 16 Fr. na prática histeroscópica permitiu, graças ao seu diâmetro reduzido, a execução de procedimentos ambulatoriais com a técnica de slicing, que aumenta e facilita as possibilidades do see and treat ambulatorial. A funcionalidade do instrumento tem se revelado satisfatória, já que permite a passagem da corrente de mono para bipolar no mesmo ressectoscópio em uso e nas mesmas alças multiuso. A nossa casuística, que compreende 1.350 pacientes e inclui variadas patologias intrauterinas e endocervicais, demonstra uma eficácia de 100% do instrumento, cuja limitação, não categórica, subordina-se aos miomas com diâmetro superior a 3 cm.

The instruments employed in surgical hysteroscopy experienced great advances in the last 30 years, allowing operators to choose from resectoscopes of 26 and 21 fr. coupled with mono or bipolar current, to the use of “office hysteroscopy”, which contemplates the use of operating systems of diameters similar to those employed in diagnostic hysteroscopy. All these options have broadened and strengthened the possibilities of surgical indications, minimizing risk and reducing sharply the contraindications. The introduction of the miniresectoscope of Gubbini of 16 fr. thanks to its reduced diameter, enabled the implementation of outpatient procedures with the technique of “slicing”, increasing andfacilitating the possibilities of “see and treat” outpatient. The functionality of the instrument has proved to be satisfactory as it allows the passage of current from mono to bipolar in the same resectoscope in use and under the same multipurpose handles. Our series,comprising 1,350 patients and including various intrauterine and endocervical pathology, demonstrates an effectiveness of 100% of the instrument, whose limitation, not categorical, is subordinated to the fibroids with diameter greater than 3 cm.
