TAVI-in-TAVI de salvamento por fratura de folheto: relato de caso / Salvage TAVI-in-TAVI for leaflet fracture: case report

INTRODUÇÃO: A longa experiência em troca valvar cirúrgica nos ensinou acerca da durabilidade limitada de biopróteses. E assim como estas, as próteses implantadas via transcateter degeneram com o tempo, requerendo intervenção adicional. O desafio torna-se ainda maior quando a indicação do procedimento deveu-se ao alto risco cirúrgico, sendo o reimplante transcateter de válvula aórtica (TAVI-in-TAVI) a única opção viável. DESCRIÇÃO DO CASO: Homem, 87 anos, idoso não frágil, foi submetido a primeira TAVI em 2016 com implante de bioprótese Acurate TF Symetis M devido à estenose aórtica grave (etiologia bicúspide e calcífica). O ecocardiograma transtorácico (ETT) pósprocedimento mostrava a bioprótese normofuncionante, orifício efetivo de fluxo (OEF) 1,8 cm², gradiente sistólico médio 8 mmHg, refluxo paraprotético discreto e fração de ejeção do ventrículo esquerdo (FEVE) de 45%. Paciente manteve-se em classe funcional (CF) I até 2024, quando foi internado por piora da dispneia, evoluindo para CF III. Realizado ETT com imagem sugestiva de fratura de folheto e disfunção biventricular importante (FEVE=35% e FAC= 22%). Como consequência de risco cirúrgico proibitivo (EUROSCORE II de 30%), optou-se pela realização de TAVI-in-TAVI após compensação clínica, porém evoluiu com choque cardiogênico e necessidade de inotrópico. Devido à instabilidade clínica não foi possível realizar tomografia computadorizada para planejamento do implante, decidido prosseguir com procedimento monitorizado por ETT. Procedimento realizado sob sedação, com angiografia para visualização de coronárias e TAVI prévia, seguido de implante de bioprótese MyVal (Meril Lifesciences) n° 24.5mm com pós-dilatação. Injeção de controle demonstrava prótese aórtica bem posicionada, refluxo paravalvar discreto com coronárias pérvias e bom fluxo. ETT pós-procedimento: endoprótese bem posicionada, abertura e mobilidade preservadas, OEF 2,1 cm², gradiente sistólico médio 3 mmHg, FEVE 36%, FAC 26%, mantendo refluxo paraprotético discreto. Recebeu alta 8 dias após TAVI-in-TAVI em CF NYHA I. CONCLUSÃO: Sabemos que TAVI-in-TAVI em pacientes selecionados, apresentam bons resultados, porém em nosso paciente foi realizado em caráter de urgência demonstrando efetividade. A intervenção percutânea TAVI-in-TAVI de urgência, mostrou-se factível diante de paciente com instabilidade hemodinâmica e resultou em melhora clínica e ecocardiográfica substanciais do paciente.

Speech perception in patients submitted to cochlear reimplantation. / Percepção auditiva da fala após o reimplante coclear.

PURPOSE: To analyze the performance of auditory speech perception (PF) after cochlear implant (CI) replacement surgery and associations with age, times of use of the first CI, deprivation, recovery and use of the second device. METHODS: The retrospective study analyzed the medical records of 68 participants reimplanted from 1990 to 2016, and evaluated with PF performance tests, considering as a reference, the greater auditory capacity identified during the use of the first CI. Also analyzed were: Etiology of hearing loss; the reasons for the reimplantation; device brands; age range; sex; affected ear; age at first implant; time of use of the first CI, deprivation, recovery and use of the second device. The analyzes followed with the Chi-Square and Spearman, Mann-Whitney and Kruskal-Wallis tests (CI=95%; p≤0.05; Software SPSS®.v22). RESULTS: Most were children with hearing loss due to idiopathic causes and meningitis. Abrupt stoppage of operation was the most common cause for device replacement. Most cases recovered and maintained or continued to progress in PF after reimplantation. Adults have the worst recovery capacity when compared to children and adolescents. The PF capacity showed a significant association (p≤0.05) with: age at first implant; time of use of the first and second CI. CONCLUSION: Periodic programming and replacement of the device when indicated are fundamental for the maintenance of auditory functions. Being young and having longer use of implants represent advantages for the development of speech perception skills.

OBJETIVO: Analisar o desempenho da percepção auditiva da fala (PF) após cirurgia de substituição do implante coclear (IC) e identificar associações com a idade, tempos de uso dos dispositivos, privação e recuperação. MÉTODO: O estudo retrospectivo analisou os prontuários de 1990 a 2016 e considerou como referência o maior escore da capacidade auditiva identificada ao longo do uso do primeiro IC. Foram coletados dados epidemiológicos; etiologia; causas da substituição e marca dos dispositivos; classificação etária; idades no primeiro e segundo implante; tempos de utilização, privação e de recuperação da capacidade auditiva. Os dados foram avaliados por meio de testes estatísticos não paramétricos (IC=95%; p<0.05). RESULTADOS: Foram avaliados 68 participantes (31 adultos e 37 crianças), sendo 52,9% do sexo feminino e as principais etiologias da perda auditiva foram: idiopática (48,5%), infecciosa (33,8%) e outras causas não infecciosas (17,6%). A idade média verificada na implantação do primeiro e do segundo IC, foram: 102±143,4 e 178,9±173,4 meses. Os tempos médios de uso do primeiro IC, privação, recuperação e uso do segundo IC, foram respectivamente: (76,1±63,3); (2,8±2,4); (6,5±7,1); (75,6±48,3) meses. A substituição foi motivada principalmente pela parada abrupta de funcionamento (77,9%) e 85,3% dos participantes recuperaram a PF, que esteve significativamente associada à idade no primeiro IC, e os tempos de utilização dos dispositivos (p<0.05). CONCLUSÃO: A maior parte dos indivíduos submetidos ao reimplante conseguem recuperar e/ou continuar o desenvolvimento das habilidades auditivas. A idade mais jovem e o tempo de uso dos dispositivos são fatores que influenciam na capacidade de recuperação da PF em reimplantados.

Long-Term Outcomes of Patients Undergoing Aortic Root Replacement With Mechanical Versus Bioprosthetic Valves: Meta-Analysis of Reconstructed Time-to-Event Data.

Background An aspect not so clear in the scenario of aortic surgery is how patients fare after composite aortic valve graft replacement (CAVGR) depending on the type of valve (bioprosthetic versus mechanical). We performed a study to evaluate the long-term outcomes of both strategies comparatively. Methods and Results Pooled meta-analysis of Kaplan-Meier-derived time-to-event data from studies with follow-up for overall survival (all-cause death), event-free survival (composite end point of cardiac death, valve-related complications, stroke, bleeding, embolic events, and/or endocarditis), and freedom from reintervention. Twenty-three studies met our eligibility criteria, including 11 428 patients (3786 patients with mechanical valves and 7642 patients with bioprosthetic valve). The overall population was mostly composed of men (mean age, 45.5-75.6 years). In comparison with patients who underwent CAVGR with bioprosthetic valves, patients undergoing CAVGR with mechanical valves presented no statistically significant difference in the risk of all-cause death in the first 30 days after the procedure (hazard ratio [HR], 1.24 [95% CI, 0.95-1.60]; P=0.109), but they had a significantly lower risk of all-cause mortality after the 30-day time point (HR, 0.89 [95% CI, 0.81-0.99]; P=0.039) and lower risk of reintervention (HR, 0.33 [95% CI, 0.24-0.45]; P<0.001). Despite its increased risk for the composite end point in the first 6 years of follow-up (HR, 1.41 [95% CI, 1.09-1.82]; P=0.009), CAVGR with mechanical valves is associated with a lower risk for the composite end point after the 6-year time point (HR, 0.46 [95% CI, 0.31-0.67]; P<0.001). Conclusions CAVGR with mechanical valves is associated with better long-term outcomes in comparison with CAVGR with bioprosthetic valves.

Rare Presentation of Sinus of Valsalva Aneurysm Treated by Aortic Valve Reimplantation Technique.

Sinus of Valsalva aneurysm is a rare cardiac abnormality which can be acquired or of congenital origin. A spontaneous rupture into the right atrium is possible and, if not adequately treated, may result in a progressive heart failure due to the left-to-right intracardiac shunt. If ruptured sinus of Valsalva aneurysm is diagnosed, surgical repair is indicated, and different surgical techniques have been reported. If concomitant aortic regurgitation is present, aortic valve replacement is usually performed. Herein, we describe an uncommon clinical presentation of a ruptured sinus of Valsalva aneurysm which has been corrected by aortic valve reimplantation.

Hand Call Practices and Satisfaction: Survey Results From Hand Surgeons in the United States.

PURPOSE: To describe current hand call practices in the United States (US) and identify aspects of call practices that lead to surgeon satisfaction. METHODS: An anonymous survey was administered to practicing members of the American Society for Surgery of the Hand, and responses were filtered to US surgeons taking hand call. Hand call was considered: (A) hand-specific call including replantation or microvascular services or (B) hand-specific call without replantation or microvascular responsibilities. Data were collected pertaining to practices, compensation, assistance, frequency, and satisfaction. Descriptive analyses were performed and regionally subdivided. Pearson correlations were used to determine aspects of a call that influenced surgeon satisfaction. RESULTS: A total of 662 US hand surgeons from 49 states responded. Among the respondents, 38% (251) participate in replantation or microvascular call, 34% (225) participate in hand-specific call excluding replantation, and 28% (186) do not participate in hand-specific call. Of those practicing hand call (476), 60% take 6 or fewer days of call per month, 62% have assistance with staffing consultations, 65% have assistance with surgical procedures, and 49% are financially incentivized to take call. More than half (51%) reported that they have a protected time for call aside from their elective practice, and 10% of the surgeons reported that they have a dedicated operating room (OR) time after a call to care for cases. Two percent reported that the day following call is free from clinical duties. Only 46% of the surgeons were satisfied with their call schedule, with the top concerns among unsatisfied respondents relating to pay, OR availability, and burnout. The factors correlating to surgeon satisfaction included less frequent call, assistance with performing consultations and surgery, pay for call, and OR availability. CONCLUSIONS: The majority of US hand surgeons are not satisfied with their current call practices, with frequent concerns relating to pay, OR availability, and burnout. CLINICAL RELEVANCE: These findings may promote awareness regarding aspects of hand call that correlate with surgeon satisfaction and highlight practice patterns that may reduce burnout.

Successful Hand Replantation Augmented by Delayed Pedicled Fascio-Cutaneous Groin Flap in an Adult Laborer: A Case Report and Literature Review.

BACKGROUND Upper limb replantation has become an almost routine procedure, with digital and hand reattachments being the most commonly performed. These remain challenging procedures to reconstructive surgeons, especially when there is trauma to the detached limb. Injury to the overlying skin and soft tissue can lead to tissue necrosis, sepsis, and loss of the replanted limb. The use of skin grafts as well as a wide variety of muscular, musculo-cutaneous, fascio-cutaneous flaps, and free-transfer grafts has significantly diminished limb loss. We report on the use of a delayed fascio-cutaneous, pedicled groin flap to cover a defect on the dorsum of a hand replanted 6 weeks earlier. CASE REPORT A right-hand-dominant male laborer had his left hand completely severed by a sharpened machete. This was surgically replanted with limb salvage but there was an area of denuded tissue on the dorsum, devoid of epidermal coverage. A fascio-cutaneous, pedicled rotational flap arising from the left groin was used as definitive cover for the defect. This flap augmented the replantation process by producing a functional and visually acceptable replant, allowing the patient to undergo rehabilitation and eventually return to the workforce. CONCLUSIONS The fascio-cutaneous, pedicled, rotational groin flap is a thin, pliable, but robust flap which covered the defect created by the initial injury with a protective tissue layer. It allowed free movement of the extensor tendons by creating a smooth surface over which they could easily glide with retention of near-normal, functional hand movement.

How we do it: robotic-assisted distal ureterectomy with ureteral reimplantation

ABSTRACT Background: High risk upper tract urothelial carcinoma (UTUC) is typically managed with radical nephroureterectomy, however, renal preservation can be attempted when UTUC is localized to the distal ureter in the presence of chronic kidney disease (1-3). Distal ureterectomy is typically managed with a ureteral reimplantation and psoas hitch in order to maintain urothelial continuity, to avoid comprising the contralateral ureter, and reducing risk of chronic urinary tract infections and electrolyte abnormalities (4). We present our case of distal ureteral UTUC managed robotically with a distal ureterectomy with ureteral reimplantation. Technique and Follow-Up: Initially, an Orandi needle on a resectoscope circumscribed the left ureteral orifice. Next, robotically, the retroperitoneum was exposed and a left sided pelvic lymphadenectomy was completed. The left ureter was mobilized and the diseased ureteral segment was transected. The mobilized bladder was sutured to psoas fascia. After a cystotomy, the ureter was re-anastomosed to the bladder. The patient was discharged on postoperative day three and re-evaluated one week later with a cystogram. Final pathology was downgraded to non-invasive low-grade papillary urothelial carcinoma with negative lymph nodes and margins. Conclusion: High risk UTUC localized to the distal ureter in the setting of chronic kidney disease can be managed with a distal ureterectomy (3). Robotic distal ureterectomy with ureteral reimplantation can be assisted by an Orandi needle to achieve negative margins. Utilizing a robotic technique can offer challenges with the ureteral spatulation and reanastomosis (5-7). By fixating the ureter to the bladder prior to reanastomosis, our technique offers a solution for these difficulties.

Origen anómalo de una de las ramas de la arteria pulmonar (OAAP): tratamiento quirúrgico y resultados / Anomalous origin of one of the branches of the pulmonary artery (AOPA): Surgical treatment and outcome

Resumen Introducción: El origen anómalo de una de las ramas de la arteria pulmonar procedente de la aorta ascendente es poco frecuente. Objetivo: Identificar las características clínicas y quirúrgicas de los pacientes sometidos a reimplante de la rama afectada. Método: Se realizó un estudio observacional, transversal, descriptivo, retrospectivo y retrolectivo, en el que se incluyeron los pacientes diagnosticados de origen anómalo de alguna de las ramas de la arteria pulmonar y que fueron tratados mediante cirugía correctiva en el Instituto Nacional de Cardiología Ignacio Chávez, en el periodo del 1 de enero de 2003 al 31 de enero de 2019. De los expedientes se extrajeron las características demográficas, los antecedentes quirúrgicos, los diagnósticos, los reportes ecocardiográficos y tomográficos, la técnica quirúrgica y el estado posquirúrgico. Resultados: Se encontraron nueve pacientes sometidos a cirugía de corrección, con un promedio de edad de 2 ± 2 años, un peso de 11.4 ± 1.5 kg y una talla de 82 ± 15 cm. El 67% fueron de sexo masculino. La rama afectada con más frecuencia fue la derecha; el 68% se originaban directamente de la aorta y el 42% de un conducto arterioso persistente. La corrección con circulación extracorpórea tuvo un tiempo promedio de pinzamiento aórtico de 35 minutos y de soporte circulatorio de 45 minutos. Se utilizó el implante directo o con material sintético. Las complicaciones fueron falla ventricular, sangrado, arritmias y neumonía nosocomial. La mortalidad fue del 11%. Conclusiones: El tratamiento quirúrgico para el reimplante de la rama anómala de la arteria pulmonar es el procedimiento de elección, y con cuidados quirúrgicos y posteriores tiene un buen pronóstico a mediano y largo plazo.

Abstract Introduction: The anomalous origin of one of the branches of the pulmonary artery from the ascending aorta is rare. Objective: To identify the clinical and surgical characteristics of the patients undergoing reimplantation of the affected branch. Method: An observational, cross-sectional, descriptive, retrospective and retrolective study was performed; patients diagnosed with anomalous origin of one of the branches of the pulmonary artery and treated by corrective surgery at the Instituto Nacional de Cardiología Ignacio Chavez, in the period from January 1, 2003 to January 31, 2019, were included. It was extracted from the files: demographic characteristics, surgical antecedents, diagnoses, echocardiographic and tomographic reports, surgical technique and post-surgical status. Results: Nine patients underwent correction surgery, with an average age of 2 ± 2 years, 11.4 ± 1.5 kg and height 82 ± 15 cm; 67% were male. The most frequent affected branch was the right, 68% originated directly from the aorta and 42% from a patent ductus arteriosus. The correction with extracorporeal circulation had an average aortic cross-clamp of 35 minutes and circulatory support of 45 minutes, the direct or synthetic implant was used. The complications were ventricular failure, bleeding, arrhythmias and nosocomial pneumonia. Mortality was 11%. Conclusions: Surgical treatment for reimplantation of the anomalous branch of the pulmonary artery is the procedure of choice, which with surgical and subsequent care has a good prognosis in the medium and long term.

Reconstrucción en amputaciones distales de dedos en niños con injerto compuesto y vendaje semioclusivo / Reconstruction of distal finger amputations in children with composite autograft and semi-oclusive dressing

La reconstrucción de una amputación distal de dedo en un niño es un desafío. Los procedimientos propuestos son muchos, y los resultados no han sido buenos. La reconstrucción con reposición del segmento a modo de injerto compuesto, o con técnicas microquirúrgicas, parece ofrecer la mejor de las posibilidades, pues se conservan estructuras irremplazables, como el lecho ungueal y el hiponiquio, lo que permite que los niños mantengan un pulpejo anatómico y con función normal. Presentamos una serie de tres pacientes pediátricos tratados con una nueva técnica, que combina la reposición del segmento, como un injerto compuesto, y el uso de curación semioclusiva (composite autograft and semi-oclussive dressing, CASOD, en inglés). Hemos observado buenos resultados.

The reconstruction of finger tip amputation in children is challenging. There are many procedures described to treat this injury, none of which present optimal results. Repositioning of the amputated segment as an autograft or with microsurgical techniques seems to offer the best outcome. It enables the preservation of otherwise irreplaceable structures, such as the nail bed and the hyponychium, thus enabling children to mantain an anatomically and functionally normal finger pad. We present a series of three pediatric patients treated with tha new technique, which combines composite autograft and semi-oclusive dressing (CASOD). The results observed so far have been promising.

Bentall-de Bono procedure for acute aortic dissection.

We present a patient with an acute type A aortic dissection that involves the aortic root. The high mortality of patients with this condition is often associated with operations performed by surgeons with minimal experience dealing with aortic diseases. Therefore, less-experienced surgeons often opt for less complicated techniques like supracoronary ascending aortic replacement. However, according to the latest guidelines for the management of aortic diseases, the aortic root should be replaced when it is compromised by the dissection. The Bentall-de Bono technique treats the aortic root and demands less experience than valve-sparing aortic surgery.

Effectiveness and risks of endoscopic management compared to vesicoureteral reimplantation in patients with high-grade vesicoureteral reflux: systematic review and network meta-analysis.

The purpose of this study is to determine the effectiveness and safety of endoscopic management compared to ureterovesical reimplantation in pediatric patients with high-grade vesicoureteral reflux in terms of urinary tract infection. We performed a network meta-analysis. We searched in MEDLINE, EMBASE, LILACS, and CENTRAL. We included clinical experiments, quasi-experiments, and cohorts studies. The population was men and women between 1 month and 15 years old. Patients had primary high-grade VUR diagnosed by voiding cystourethrography. The interventions were subureteric bulking agent endoscopic injection (polytetrafluoroethylene, hyaluronic acid, collagen, Dx/Ha, and PPC) vs vesicoureteral reimplantation (Cohen, Politano-Leadbetter, Glenn-Anderson, and Lich-Gregoir), and the primary outcome was urinary infections. Nine studies accomplished the inclusion criteria (seven observational and two clinical experiments). A total of 1448 renal units underwent surgical treatments for the correction of high-grade VUR. Regarding the primary outcome, we compared Dx/Ha with Cohen, Lich-Gregoir, and PPC, finding an RD of -0.02 (95%CI -0.09 to 0.06), RD of -0.02 (95%CI -0.10 to 0.07), and an RD of -0.03 (- 0.13 to 0.07), respectively.Conclusion: Our study showed that there were no differences in UTI episodes after VUR correction in patients undergoing endoscopic management compared with vesicoureteral reimplantation. What is Known: • Primary vesicoureteral reflux is one of the most common congenital anomalies of the urinary tract. • The clinical practice guidelines recommend the surgical management of patients with high-grade VUR. What is New: • There were no differences in UTI episodes after VUR correction in patients undergoing endoscopic management compared with vesicoureteral reimplantation.

Introduction: The thumb is the greatest functional finger of the hand, which is justifies its replantation and rehabilitation. Objective: To carry out a retrospective analysis of the medical records of patients undergoing thumb reimplantation, performed by the SOS-Reimplantation Service of the State Hospital Adão Pereira Nunes. Methodology: This is a retrospective study with a convenience sample, covering the period between January 2010 and December 2015, conducted thorough medical records of patients undergoing the process of thumb replantation, attended at the Occupational Therapy Service / TO - Hand at the Adão Pereira Nunes State Hospital, in Duque de Caxias, Rio de Janeiro. Sociodemographic information was collected, in addition to muscle strength, sensitivity, and rehabilitation time. Results: 63 medical records of patients who underwent thumb reimplantation procedure, aged 18 to 65 years, were reviewed. As for the accident site, 76.1% of the cases were due to occupational accidents and 23.2% to domestic accidents. When observing the laterality of the lesion, 92% of the patients were righthanded, while the thumb with the largest number of lesions was left, with a total of 82.5% patients. As for the level of the lesion, 25.3% of patients suffered an injury to the proximal phalanx, 20.8% of patients suffered an injury to the interphalangeal region, and 53.9% of the patients had lesions to the distal phalanx. Among those referred for further evaluation, 28.5% of patients underwent other surgical procedures. There was overall strength gain in 88.2% of patients in sensitivity. Conclusion: Most patients who underwent thumb reimplantation were able to obtain gains in muscle strength and sensitivity, being able to return to their work activities, with a rehabilitation time that varied from 4 to 14 months.

Anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) in adults: Collateral circulation does not preclude direct reimplantation.

BACKGROUND: The adult type of anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) is characterized by late presentation due to collateral coronary flow. Patients often present with long time recurrent angina or dyspnea. Surgical correction can be a challenge due to the vast collateral coronary circulation. CASE PRESENTATION: A previously healthy 41-year-old male presented in the emergency room referring typical angina and dyspnea. Coronary angiography revealed ALCAPA. Surgical correction was indicated. Under cardiopulmonary bypass, the left main coronary artery ostium was isolated and directly reimplanted in the aorta. The patient was discharged from the hospital without complications and asymptomatic. Control coronary angiography showed enlarged left main coronary artery and regression of the collateral circulation. CONCLUSION: Even with a well-developed collateral circulation, detachment of the left coronary artery and direct implantation in the aorta is feasible, achieving good long-term results.

Reimplante de falange distal de dedo sin anastomosis venosa con anestesia local / Distal phalanx replantation under local anesthesia and without venous anastomosis

Presentamos a un paciente que sufrió una amputación traumática de la falange distal del 5to dedo de su mano izquierda, y fue tratado mediante un reimplante sin anastomosis venosa. En el mismo acto quirúrgico, se le realizó una artrodesis definitiva con clavijas. La cirugía se efectuó con anestesia troncular del dedo, por lo cual no se requirió de un anestesista ni fue necesario un tiempo adecuado de ayuno. Debido a la localización distal de la amputación y a la ausencia de una vena dorsal viable para ser anastomosada, se optó por un drenaje venoso controlado mediante la extracción de la placa ungueal, el frotado del lecho ungueal y la colocación periódica (cada 3 h, por 7 días) de una gasa impregnada con heparina. Además, el paciente fue anticoagulado con enoxaparina 40 mg y ácido acetilsalicílico cada 24 h, por 21 días. El reimplante fue exitoso. Nivel de Evidencia: IV

We present a patient who experienced a traumatic amputation of his left fifth finger distal phalanx, and was treated using replantation without venous anastomosis. The same surgical procedure also included a final arthrodesis with Kirschner wires. Surgery was performed with digital block anesthesia, which did not require the presence of an anesthesiologist nor fasting. The distal level of the amputation and the lack of viable options for dorsal vein anastomosis motivated our decision for venous drainage controlled by nail-plate removal, nail-bed scrubbing and periodic (every 3 hours during 7 days) dressing with heparin-impregnated gauze. In addition, the patient received anticoagulant therapy with aspirin and enoxaparin 40 mg every 24 hours for 21 days. The replantation procedure was a success. Level of Evidence: IV

Comparison of Cohen and Lich-Gregoir ureteral reimplantation in the surgical management of primary unilateral vesicoureteral reflux in children.

OBJECTIVE: Vesicoureteral reflux (VUR) represents one of the most significant risk factors for acute pyelonephritis in children. Various intravesical and extravesical techniques have been described for the surgical correction of VUR. The aim of our study was to compare the results of open intravesical and extravesical procedures for unilateral primary VUR in children. METHODS: Between January 2012 and August 2018, 38 children with primary VUR who underwent open ureteral reimplantation surgery were retrospectively reviewed. The Cohen (intravesical) and the Lich-Gregoir (extravesical) approach were grouped as groups A and B, respectively. The groups were compared for age, gender, preoperative reflux grade, presence of lower urinary tract symptoms, operation time, discomfort and pain, analgesic requirements, duration of hematuria, postoperative complications, and hospital stay. All the parameters were statistically compared. RESULTS: There were 38 patients in this study. Group A had 18 patients, and group B had 20 patients. The mean operative time was significantly shorter in group B than in group A. The mean hospital stay was also shorter in group B. The urethral foley stay period was 4.7±0.9 days 2±0 days (p = 0.000*), respectively, for group A and B. Macroscopic hematuria was seen in group A. The objective pain scale was worse after intravesical surgery. Analgesic requirements were higher in group A (p =0.131). CONCLUSION: Intravesical and extravesical ureteroneocystostomy methods are equally successful and feasible in the treatment of primary unilateral VUR. The Cohen technique is associated with a longer and more painful hospital stay, gross hematuria, and longer operative time, compared to the Lich-Gregoir technique.

Evolving surgical management of pediatric vesicoureteral reflux: is open ureteral reimplantation still the 'Gold Standard'?

ABSTRACT Vesicoureteral reflux, the retrograde flow of urine from the bladder into the upper urinary tract, is one of the most common urologic diagnoses in the pediatric population. Once detected, therapeutic options for urinary reflux are diverse, ranging from observation with or without continuous low-dose prophylactic antibiotics to a variety of operative interventions. While a standardized algorithm is lacking, it is generally accepted that management be tailored to individual patients based on various factors including age, likelihood of spontaneous resolution, risk of subsequent urinary tract infections with renal parenchymal injury, and parental preference. Anti-reflux surgery may be necessary in children with persistent reflux, renal scarring or recurrent pyelonephritis after optimization of bladder and bowel habits. Open, laparoscopic/robot-assisted and endoscopic approaches are all successful in correcting reflux and have been shown to reduce the incidence of febrile urinary tract infections.
