    (2023) MELLO, Marcos Figueiredo; LOCALI, Rafael Fagionato; ARAUJO, Rogerio Mattos; REIS, Joceara Neves; SAIOVICI, Samuel; MELLO, Luiz Figueiredo; ROCHA, Flavio Eduardo Trigo
    Background Monosymptomatic enuresis (MNE) results from a pathogenic triad that may include lack of vaso-pressin secretion during sleep, reduced functional bladder capacity and inability to wake up during sleep. The treatment of MNE can be performed through behavioral therapy, use of alarms or medi-cations such as desmopressin and imipramine.Objective To compare the effectiveness of different treat-ments of MNE.Study design Prospective and randomized study comparing different intervention and a control group (receiving only behavior therapy) for MNE. Inclusion criteria: age between 5 and 16 years old, with MNE, evalu-ated at the pediatric urology outpatient clinic of Hospital Infantil Menino Jesus. At first visit children were submitted to behavior therapy (urotherapy) for 3 months, children were subsequently characterized according to the ICCS as non-responders, partial responders, or full responders. Those partial re-sponders or non-responders received a patient ID and were randomized to four groups: Alarm Group (G1), Desmopressin Group -DDAVP (G2), Imipramine Group (G3) and Control (G4). All groups were moni-tored monthly, for a period of 6 months. After 6 months, the children were reevaluated for MNE.Results 93 patients were enrolled. Mean age was 10.96 years with a standard deviation of 2.28 years, 59,1% were male. All groups had improvement in the number of dry nights (Table). Taking in account success the population full responders and partial responders: Alarm Group (G1) achieve success in 100% of cases, Desmopressin Group -DDAVP (G2) in 63.6% of cases, Imipramine Group (G3) in 73.7% of cases (Table 3). No drugs side effects were observed in both groups (G2 and G3), there was no dropout in patients who used alarms.Discussion Our data suggests that the use of alarms is the most effective treatment of ENM with superior results when compared to imipramine and DDAVP. The small number of participants is a weakness of the study, as well as the lack of a voiding diary at the end of the study.Conclusion All therapeutics options utilized in the treatment of MNE are safe, effective and has a low rate of abandonment.

    Urethral duplication type influences on the complications rate and number of surgical procedures
    (2017) LOPES, Roberto Iglesias; GIRON, Amilcar Martins; MELLO, Marcos Figueiredo; BARBOSA NETO, Cristovao Machado; SANTOS, Joana dos; MOSCARDI, Paulo Renato Marcelo; SROUGI, Victor; DENES, Francisco Tibor; SROUGI, Miguel
    Introduction: Urethral duplication is rare. Characterized by the presence of two urethral channels. This anomaly presents a great variety of clinical findings that depend on the type of duplication that often is associated with other anomalies. Material and Methods: We report thirteen boys with urethral duplication managed in our institution between 1988-02015. Clinical findings, associated anomalies, treatment of urethral duplication and our results are described. Patients were classified according to Effmann classification. Results: Mean patient's age was 38.3 +/- 34.7 months (3-0136 months). Mean follow-up was 7.7 +/- 3.4 years (3y8m-014y2m). Type II A2 was the most common pattern (8/13 patients, 61.5%), followed by type IA (3/13 patients, 23%) and IIA1 (2/13 patients, 15.3%). The most frequent clinical manifestations were urinary tract infections (UTI) observed in 11/13 patients (84.6%) and anal urinary leakage, found in 7/13 patients (53.8%). Associated anomalies were found in 9/13 patients (69.2%). Required surgeries were 3.53 +/- 2.84 procedures per patient. Considering groups: Type IIA2 4.25 +/- 3.28, type IIA1 4 +/- 1.41 and type IA 1.33 +/- 0.57 needed procedures per patient. Complications rate were 0% for type IA, 50% for type IIA1 and 75% for type IIA2. Conclusions: Patients with incomplete duplication (type I A or I B) can totally be asymptomatic, with no need of surgical correction. Type IIA2 is the most complex form of duplication to correct and multiple procedures might be required because of the very hypoplastic orthotopic dorsal urethral tissue. Surgical treatment should be individualized and parents should be advised on complications and need of multiple surgeries according to urethral duplication type.

    Single-stage Abdominoplasty Using Groin Flaps Without Osteotomies: Management of Exstrophy-epispadias Complex
    (2018) GIRON, Amilcar Martins; MELLO, Marcos Figueiredo; BERJEAUT, Ricardo Haidar; MACHADO, Marcos Giannetti; SILVA, Gabriel Carvalho dos Anjos; CEZARINO, Bruno Nicolino; OLIVEIRA, Lorena Marcalo; LOPES, Roberto Iglesias; DENES, Francisco Tibor
    BACKGROUND The optimal treatment for children born with exstrophy-epispadia complex is still a matter of AND OBJECTIVE debate.(1,2,3) We demonstrate the Single-Stage Abdominoplasty using Groin Flap technique to close the abdominal wall of children with classic bladder exstrophy (CBE) without osteotomy neither radical soft tissue mobilization. Advantages over current techniques are less risk of penile tissue loss and avoidance of osteotomies. MATERIAL AND METHODS Abdominal wall repair consists in using the hypogastric skin, rectus, and obliquus externus abdom inalis muscle fascial flaps. These groin flaps are rotated medially resulting in a very strong abdominal wall support. Groin flaps are made of rectus anterior fascia rotated medially, flipped over, and sutured with Prolene sutures to close the defect. By rotating the fascial flaps medially, complete reinforcement of the abdominal wall to the level of the pubic bone is achieved. This permits abdominal closure maintenance without tension. RESULTS Groin flap was applied to 128 patients with CBE referenced from all over the country. Most of these patients returned to their home areas making difficult their follow up. However, we have 44 cases that have regular clinical visits. Mean follow-up was 10.3 4.5 years (2 years 8 months-16 years). Successful closure was achieved in 43 patients (97.7%) as a single procedure; one patient had a complete wound dehiscence and needed another reconstruction (2.2%). Four patients (9.1%) presented abdominal hernias that needed surgical management. When continence is evaluated, we present similar literature rates (60%).(4) CONCLUSION Abdominal reconstruction using Groin flaps has advantages over the traditional approaches to CBE. It reduces the surgical steps and facilitates the closure of the abdominal wall without the need of osteotomies and consequent immobilization during the postoperative period. It is feasible at any age and can be also very useful as a salvage technique even after previous failed procedures. Finally, it minimizes the number of surgeries. (C) 2018 Elsevier Inc.

    Step-by-step Laparoscopic Vesiculectomy for Hemospermia
    (2017) MELLO, Marcos Figueiredo; ANDRADE, Hiury Silva; SROUGI, Victor; ARAP, Marco Antonio; MITRE, Anuar Ibrahim; DUARTE, Ricardo Jordao; SROUGI, Miguel
    Hemospermia has been considered as a benign and self-limiting condition. It usually has an inflammatory or infectious cause. However, recurrent or persistent hemospermia may indicate a more serious underlying pathology, especially over 40 years of age. Biopsy or surgical excision is indicated in cases of suspicious findings during investigation, such as cysts or masses. Open surgery has been considered the definitive form of treatment, however, it can be associated with significant morbidity. With growing experience in laparoscopics, this approach is becoming the preferable way to access the seminal vesicles. Our objective is to demonstrate a step-by-step operative technique for laparoscopic unilateral vesiculectomy approach in a man with hemospermia. Case: A 61 year-old man presented with 1 year of hemospermia. He was treated empirically with a fluoroquinolone plus a nonsteroidal anti-inflammatory without resolution of symptoms. Ultrasonography and MRI showed a solid-cystic mass in the right seminal vesicle. The patient was submitted to a laparoscopic unilateral vesiculectomy. Histopathological analysis showed intraluminal dilatation with blood content. During follow-up, complete resolution of symptoms was seen. Results: Three patients composed our cohort. Mean age was 53 years-old (range 45-61 years), the right side was more commonly affected (two unilateral on the right and bilateral). Mean operative time was 55 minutes (range 40-120min). One patient presented amyloidosis in the histopathological analysis. All cases presented complete resolution of symptoms. Conclusions: Laparoscopic vesiculectomy is a safe and feasible approach in cases of hemospermia. This technique showed good outcomes and minimal morbidity.

    One - staged reconstruction of bladder exstrophy in male patients: long - term follow-up outcomes
    (2017) GIRON, Amilcar Martins; MELLO, Marcos Figueiredo; CARVALHO, Paulo Afonso; MOSCARDI, Paulo Renato Marcelo; LOPES, Roberto Iglesias; SROUGI, Miguel
    Introduction: The surgical correction of bladder exstrophy remains challenging. In our institution, the repair has evolved from a staged repair to one-stage reconstruction. The one-stage reconstruction includes; bladder closure, Cantwell-Ransley neourethroplasty and abdominoplasty using groin flaps, without the need of pelvic ostheotomies. Repair of urinary continence (UC) and vesicoureteral reflux (VUR) is done after development of the infant. Objective: To present our experience of our modified one-stage reconstruction of bladder exstrophy in male patients. Materials and Methods: Medical records of male patients submitted to one-stage reconstruction of bladder exstrophy were analyzed retrospectively. Fifteen exstrophy bladder patients with mean age 4.2 +/- 7 years were treated at our institution between 1999-2013. Results: Eleven patients were referred to us after previous surgery. Sixteen procedures were performed; one patient had complete wound dehiscence and needed another reconstruction (6.7%). Mean follow up was 10.3 +/- 4.5 years. No patient has had a loss of renal function. Postoperative complications: four patients (26.6%) presented small fistulas, one presented penile rotation. Eleven patients (73.3%) patients underwent bladder-neck surgery. Five (33.3%) required bladder augmentation. Three cases (20%) needed subsequent treatment of VUR. At the time of our review nine (60%) patients achieved UC, two (13.3 %) patient without additional procedure. A mean of 3 +/- 1.1 procedures (2-5) was accomplished per children. Conclusions: One-stage reconstruction minimizes the number of surgical procedures required to achieve UC and potentiates bladder-neck function. The advantages of using groin flaps over current techniques for complete repair are the small risk for penile tissue loss and the avoidance of ostheotomies.

    Ureteral clipping for the treatment of a non-functioning upper kidney moiety associated with a massive ureterocele: step-by-step description of a novel technique
    (2019) LOPES, R. I.; MELLO, M. F.; KOYLE, M. A.; LORENZO, A. J.
    Objective The objective of this video is to illustrate feasibility of the ureteral ligation for the treatment of massive ureteroceles associated with non-functioning upper kidney moieties in duplex kidneys. Materials and methods In this video, one case is presented to demonstrate this novel technique. A nine-year-old boy presented with progressive lower urinary tract symptoms. Radiological workup depicted a duplex kidney on the left side with the absence of function on the upper pole and hydroureteronephrosis with a massive ureterocele. Laparoscopic ureteral transection, drainage, and ligation of both extremities of the enlarged ureter (upper pole ureter) were performed. Results Immediately after ureteral ligation, ultrasonic evidence of ureterocele decompression and improved hydroureteronephrosis was observed. This patient remained asymptomatic without postoperative complications after 3 years. De novo reflux was not observed. Conclusion Ureteral ligation, as demonstrated in the video, is a good approach for the treatment of massive ureteroceles associated with non-functioning upper kidney moieties in duplex kidneys. Compared with the current standard techniques (incision/puncture), ureteral ligation has the clear advantage of not causing 'de novo reflux' or unsuccessful deobstruction, and is not as surgically demanding as other reconstructive/ablative techniques. The disadvantage is the need of regular clinical and ultrasonographic follow-up.

    A large 15-year database analysis on the influence of age, gender, race, obesity and income on hospitalization rates due to stone disease
    (2016) MELLO, Marcos F.; MARCHINI, Giovanni Scala; CAMARA, Cesar; DANILOVIC, Alexandre; LEVY, Renata; ELUF-NETO, Jose; SROUGI, Miguel; MAZZUCCHI, Eduardo
    Purpose: To assess the public hospitalization rate due to stone disease in a large developing nation for a 15-year period and its association with socio-demographic data. Materials and Methods: A retrospective database analysis of hospitalization rates in the Brazilian public health system was performed, searching for records with a diagnosis code of renal/ureteral calculi at admission between 1998-2012. Patients managed in an outpatient basis or private care were excluded. Socio-demographic data was attained and a temporal trend analysis was performed. Results: The number of stone-related hospitalizations increased from 15.7%, although the population-adjusted hospitalization rate remained constant in 0.04%. Male: female proportion among hospitalized patients was stable (49.3%: 50.7% in 1998; 49.2%: 50.8% in 2012), though there was a significant reduction in the prevalence of male hospitalizations (-3.8%; p=0.041). In 2012, 38% of hospitalized patients due to stone disease had 40-59 years-old. The >= 80 years-old strata showed the most significant decrease (-43.44%; p=0.022), followed by the 20-39 (-23.17%; p<0.001) and 0-19 years-old cohorts (-16.73%; p=0.012). Overall, the lowest relative hospitalization rates were found for yellow and indigenous individuals. The number of overweight/obese individuals increased significantly (+20.6%), accompanied by a +43.6% augment in the per capita income. A significant correlation was found only between income and obesity (R=0.64; p=0.017). Conclusions: The prevalence of stone disease requiring hospitalization in Brazil remains stable, with a balanced proportion between males and females. There is trend for decreased hospitalization rates of male, <40 and >= 80 years-old individuals. Obesity and income have a more pronounced correlation with each other than with stone disease.

    Evaluating TIMP-2 and IGFBP-7 as a predictive tool for kidney injury in ureteropelvic junction obstruction
    (2022) MELLO, Marcos Figueiredo; BESSA JUNIOR, Jose de; REIS, Sabrina T.; KONDO, Enzo Yagi; YU, Luis; DENES, Francisco Tibor; LOPES, Roberto Iglesias
    A major challenge in the management of ureteropelvic junction obstruction (UPJO) is the selection of patients who would benefit from surgical treatment. Tissue inhibitor metalloproteinase-2 (TIMP-2) and insulin-like growth factor-binding protein 7 (IGFBP7) indicate renal cell stress and are associated with cell cycle arrest. The [TIMP-2] [IGFBP7] ratio (Nephrocheck (R)) has been recently applied in patients in intensive care units patients to predict the development of acute kidney injury. In this study, we evaluated the performance of these biomarkers performance to distinguishing obstructive hydronephrosis (HN) from non-obstructive HN. Materials and Methods: Consecutive patients with UPJO were enrolled in this study. Urinary [TIMP-2] [IGFBP7] and clinical characteristics (hydronephrosis grade, differential renal function, and drainage half-time) were measured in the following groups: 26 children with obstructive HN at initial diagnosis (group IA) and after six months of dismembered pyeloplasty (group 1B); 22 children with non-obstructive HN (group 2), and 26 children without any urinary tract condition, as the control group (group 3). Results: Comparing the initial samples, [TIMP-2] [IGFBP7] had higher levels in the HN groups and lower levels in the control group; however, no difference was observed between the HN groups (obstructive vs. non-obstructive). After six months of followup, patients who underwent dismembered pyeloplasty showed stability in the urinary concentration of [TIMP-2] [IGFBP7]. All patients with [TIMP-2] [IGFBP7] higher than 1.0 (ng/mL)(2)/1000 had diffuse cortical atrophy on ultrasonography. Conclusions: We showed that urinary levels of urinary [TIMP-2] [IGFBP7] are higher in children with HN than controls. Nephrocheck (R) is not reliable in predicting the need for surgical intervention for pediatric patients with UPJO.
