- Surgical method influences specimen margins and biochemical recurrence during radical prostatectomy for high-risk prostate cancer: a systematic review and meta-analysis(2017) SROUGI, Victor; BESSA JR., Jose; BAGHDADI, Mohammed; NUNES-SILVA, Igor; COSTA, Jose Batista da; GARCIA-BARRERAS, Silvia; BARRET, Eric; ROZET, Francois; GALIANO, Marc; SANCHEZ-SALAS, Rafael; CATHELINEAU, XavierPurpose To perform a meta-analysis comparing the rates of positive surgical margins (PSM) and biochemical recurrence (BCR) between open radical prostatectomy (ORP) and robot-assisted radical prostatectomy (RARP) in patients with high-risk prostate cancer. Methods A systematic review was performed on Pubmed, Embase and Scopus databases in August 2016, according to the Preferred Reporting Items for Systematic Review and Meta-analysis (PRISMA) statement. References retrieved were evaluated using the Newcastle-Ottawa scale and the Black and Down's tool for quality assessment. Results Nine retrospective cohorts comparing ORP and RARP were selected and included in the meta-analysis. All studies reported the PSMs. Patients treated with RARP presented less risk of PSMs (risk difference -0.04, p 0.02) than those treated with ORP. Five articles reported hazard ratios for BCR-free survival. Patients treated with RARP had less risk of BCR (HR 0.72, 95% CI 0.58-0.89) than those treated with ORP. Reports for PSM assessment were considered of adequate quality, while the studies retrieved for BCR assessment were considered limited because of the heterogeneity of their results. Conclusion Patients with high-risk prostate cancer treated with RARP have less risk of having PSM and BCR when compared to those treated with ORP. A strong conclusion is precluded due to the observational nature of the studies retrieved for our analysis.
conferenceObject FACTORS ASSOCIATED WITH SEVERE SEPTIC EVENTS AFTER SURGICAL DECOMPRESSION OF OBSTRUCTING URETERAL STONES: A PROSPECTIVE ANALYSIS(2016) MARCHINI, Giovanni; MOSCARDI, Paulo; SROUGI, Victor; VICENTINI, Fabio; TORRICELLI, Fabio; BRITO, Artur; CAMARA, Cesar; SROUGI, Miguel; MAZZUCCHI, Eduardo- Internal validation and decision curve analysis of a preoperative nomogram predicting a postoperative complication in pheochromocytoma surgery: An international study(2020) PHILLIPS, John; BLOOM, Jonathan; YARLAGADDA, Vidhush; SCHULTZ, Luciana; GORDETSKY, Jennifer; TANNO, Fabio Y.; CHAMBO, Jose L.; ALMEIDA, Madson Q.; V, Maria C. B. Fragoso; SROUGI, Miguel; SROUGI, Victor; RAIS-BAHRAMI, SoroushObjectives To develop a preoperative nomogram that would predict the risk of a postoperative complication for pheochromocytoma patients undergoing adrenalectomy using an international database. Methods We retrospectively analyzed preoperative variables and postoperative outcomes in patients who underwent adrenalectomy for pheochromocytoma in three institutions from 2000 to 2017. Internal validation of a generated nomogram was carried out with receiver operating characteristics, calibration plots, and decision curve analyses. Results A total of 153 patients who had undergone 166 adrenalectomies were included in the study. Overall, post-adrenalectomy complications were seen in 30% of patients, whereas 9.6% of patients sustained a Clavien >= 3a complication. Independent predictors of a complication were a history of hypertension, body mass index, tumor size, and Charlson Comorbidity Index score. On internal validation, the multivariable model generated a nomogram that predicted a postoperative complication or clinically hemodynamic event with an area under the curve of 0.86, showed good calibration and had an overall net benefit. Conclusions An internally validated nomogram combining body mass index, Charlson Comorbidity Index score and tumor size can predict the probability of a post-adrenalectomy complication in those with and without hypertension. The model, the first of its kind in pheochromocytoma surgery, identifies patients at risk of a postoperative complication at the time of their presentation with pheochromocytoma.

- 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, MiguelIntroduction: 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.
- Pyeloplasty in Adults With Ureteropelvic Junction Obstruction in Poorly Functioning Kidneys: A Systematic Review(2021) FREITAS, Pedro. F. S.; BARBOSA, Joao. A. B. A.; ANDRADE, Hiury S.; ARAP, Marco A.; MITRE, Anuar I.; NAHAS, William C.; SROUGI, Miguel; DUARTE, Ricardo J.; SROUGI, VictorOBJECTIVES To systematically summarize the available evidence concerning the impact of pyeloplasty on symptoms and differential renal function (DRF) in adults with unilateral UPJO in poorly functioning kidneys (PFK), and to identify potential predictors of kidney function recovery that could help clinicians select candidates for pyeloplasty. METHODS A literature search (MEDLINE, Embase, Google Scholar, Scopus, ClinicalTrials.gov, and the WHO Clinical Trials Registry) and systematic review were performed up to September 2020 according to the PRISMA guidelines. PFK were defined as a baseline DRF =30% on renal scintigraphy. The primary endpoints were symptom relief and postoperative scintigraphic DRF. Predictors of kidney function recovery were evaluated and compared among studies. RESULTS Nine studies comprising 731 patients met the inclusion criteria and were included for evidence synthesis. A DRF increase >5% occurred in 13.3%-53.8% of 160 patients with a pre- and postoperative renal scan. Symptoms improved in 73.3%-93.3% of 141 adults after pyeloplasty. Neither patient's age, baseline DFR, comorbidities, degree of hydronephrosis, kidney parenchymal thickness, nor kidney biopsy findings consistently predicted a significant DRF increase among 375 patients undergoing pyeloplasty. CONCLUSION Based on a low level of evidence, pyeloplasty may relieve symptoms and stabilize kidney function in adults with UPJO in PFK. A significant number of patients showed a DRF increase >5%, yet no consistent predictor of kidney function recovery was identified. Until more evidence becomes available, pyeloplasty could be considered for selected cases after accounting for the risks of a failure requiring a future nephrectomy. (C) 2021 Elsevier Inc.
- The influence of interstitial cells of Cajal density in the outcomes of pyeloplasty in adults: A prospective analysis(2023) SROUGI, Victor; BANDEIRA, Rodolfo Anisio Santana de Torres; REIS, Sabrina Thalita; SANTOS, Gabriel Arantes dos; ANDRADE, Hiury da Silva; LEITE, Katia Ramos Moreira; HAMILTON-CHO, David; MITRE, Anuar Ibrahim; ARAP, Marco Antonio; SROUGI, Miguel; DUARTE, Ricardo JordaoPurpose: To evaluate if the density of interstitial cells of Cajal (ICC) in the ureteropelvic junction (UPJ) influences the outcomes of pyeloplasty in adults. Methods: Twenty-three patients with the diagnosis of ureteropelvic junction obstruction (UPJO) that underwent laparoscopic dismembered pyeloplasty were included. ICC density was measured using immunohistochemistry reaction for c-KIT expression in the resected UPJ segment. Pyeloplasty outcome was evaluated by patient self-report pain, urinary outflow using DTPA renogram and hydronephrosis assessment using ultrasound (US) at 12 months of follow-up. A logistic regression analysis was performed to assess the association of pyeloplasty outcomes and ICC density. Results: Low, moderate, and high ICC density were present in 17.4%, 30.4%, and 52.2% of the patients, respectively. Complete pain resolution was observed in 100%, 85.7%, and 75% of patients with low, moderate and high ICC density, respectively (p = 0.791). DTPA renogram improved in 75%, 85.7%, and 91.7% of patients with low, moderate and high ICC density, respectively (p = 0.739). Hydronephrosis improved in 25%, 85.7%, and 91.7% of patients with low, moderate and high ICC density, respectively (p = 0.032). Conclusions: Patients with high ICC density have a significant amelioration of hydronephrosis after pyeloplasty. However, ICC density is not associated with functional outcomes.
conferenceObject A NEW INSIGHT FOR THE TREATMENT OF PRIMARY MACRONODULAR ADRENAL HYPERPLASIA: ADRENAL SPARING SURGERY EARLY OUTCOMES(2017) TANNO, Fabio; SROUGI, Victor; BRONDANI, Vania; ALMEIDA, Madson; MENDONCA, Berenice; SROUGI, Miguel; CHAMBO, Jose; FRAGOSO, Maria- 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, MiguelHemospermia 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.
