    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, Victor
    OBJECTIVES 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 Jordao
    Purpose: 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.

    The role of urinary KIM-1, NGAL, CA19-9 and beta 2-microglobulin in the assessment of ureteropelvic junction obstruction in adults
    (2017) MIRANDA, Eduardo P.; DUARTE, Ricardo J.; BESSA JR., Jose de; LOPES, Roberto I.; SROUGI, Victor; ANDRADE, Hiury S.; BANDEIRA, Rodolfo A. S. T.; ARAP, Marco A.; MITRE, Anuar I.; VIANA, Nayara I.; REIS, Sabrina T.; LEITE, Katia R. M.; SROUGI, Miguel
    Purpose: The objective of this study is to evaluate the diagnostic properties of urinary biomarkers in adults with ureteropelvic junction obstruction: KIM-1, NGAL, CA19-9, and beta 2-microglobulin. We also assessed urinary biomarker concentrations following pyeloplasty. Material and methods: We prospectively studied adults from December 2013 to February 2015. We included 47 patients with a mean age of 38.6 +/- 12.7 years. Each patient provided four samples of voided urine for biomarker measurement, one at pre-operative consultation and the others at 1, 3, and 6 months of post-operative follow-up. The control group consisted of 40 healthy individuals with no hydronephrosis on ultrasound evaluation. Results: KIM-1 had an area under the curve of 0.79 (95% CI 0.70-0.89), NGAL 0.71 (95% CI 0.61-0.83), CA19-9 0.70 (95% CI 0.60-0.81), and beta 2-microgloblin 0.61 (95% CI 0.50-0.73). KIM-1 was the most sensitive marker with a cut-off of 170.4 pg/mg creatinine (sensitivity 91.4%, specificity 59.1%), whereas CA19-9 was the most specific with a cut-off of 51.3 U/mg creatinine (sensitivity 48.9%, specificity 88.0%). Urinary concentrations of biomarkers decreased after pyeloplasty. Conclusions: The evaluation of urinary biomarkers is useful in adults undergoing pyeloplasty. KIM-1, NGAL, and CA19-9 were elevated and significantly decreased after surgery.

    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.

    Laparoscopic Ureterocalicostomy Technique
    (2023) NUNES, Romulo S. S.; SUARTZ, Caio V.; ANDRADE, Hiury S.; JORDAO, Ricardo D.; SROUGI, Victor; MITRE, Anuar I.; NAHAS, William C.; ARAP, Marco A.
    Purpose: Ureterocalicostomy is a technique that was first described by Neuwirt in 1948 (1) The laparoscopic access was initiated in 2003 by Cherullo et al. (2), following the established principles of open surgery. In 2004, Gill et al. had two patients with UPJO treated with laparoscopic ureterocalicostomy, with success (3). In 2014, Arap et. al. presented a case series with good results in adults and children in our service (4). There are factors that prepare the surgeon for an ureterocalicostomy, such as the renal cortex thickness, although the decision is mainly taken during the procedure (5).Material and Methods: A 24 years-old female patient with right lumbar pain was referred to our institution. She already had a right open pyeloplasty two years ago. The CT scan presented a right hydronephrotic kidney, DMSA scan with 30% of relative function and a DTPA scan with an obstructive pattern.Results: A laparoscopic ureterocalicostomy was performed due to the intra-operative findings (inferior kidney pole thickness and challenging access to the uretero-pelvic junction). The overall time was 130 minutes with no complications. The patient was discharged in two days and the double J was withdrawn in four weeks. The CT scan within one year demonstrates a reduction of the hydronephrosis. She had no more lumbar pain.Conclusion: In complex cases, the laparoscopic ureterocalicostomy proves to be a safe and efficient procedure, with a free tension-free anastomosis and the advantages of the laparoscopic access.

    Postoperative Renal Function in Patients Undergoing Unilateral Nephrectomy: Development of a Prediction Model Using Preoperative Risk Factors and Cr-51-EDTA Clearance
    (2020) ANDRADE, Hiury S.; SROUGI, Victor; ARAP, Marco A.; MITRE, Anuar I.; CAMARGO, Cristina P.; ZARGAR, Homayoun; KAOUK, Jihad H.; NAHAS, Willian C.; SROUGI, Miguel; DUARTE, Ricardo J.
    Objectives: To analyze the preoperative variables associated to the postoperative glomerular filtration rate (GFR) outcomes after nephrectomy for benign and malignant conditions, measured by the reference isotopic technique Cr-51-ethylene diamine tetra-acetic (Cr-51-EDTA) and to create a model to predict the short-term postoperative GFR. Secondary aim was to evaluate which of the common equations for GFR estimation (Cockcroft-Gault, Modification of Diet in Renal Disease [MDRD] or Chronic Kidney Disease Epidemiology Collaboration [CKD-EPI]) has the best correlation with the Cr-51-EDTA. Methods: Patients undergoing unilateral nephrectomy from 2014 to 2018 were selected. Pre- and postoperative variables were prospectively collected. Univariate and multivariate analyses were done to identify independent risk factors associated with renal function outcomes and to create a model to predict the postoperative GFR. Correlation analyses were performed to evaluate the performance of various serum creatinine-based equations for GFR estimation compared with Cr-51-EDTA. Results: In total, 107 patients were evaluated. After univariate and multivariate analyses, older age (p = 0.008), higher split function of the operated kidney on dimercaptosuccinic acid (DMSA) scintigraphy (p < 0.001), and lower preoperative Cr-51-EDTA (p < 0.001) were independent risk factors for higher GFR decline. Correlation analyses showed that GFR estimated by CKD-EPI equation had the best concordance to GFR measured by Cr-51-EDTA. Conclusions: Based on our findings age, DMSA and lower preoperative Cr-51-EDTA are predictors of postoperative renal function after unilateral nephrectomy. For the assessment of estimated GFR, CKD-EPI equation appears to have the best concordance with Cr-51-EDTA.
