Clinical implications of a rare renal entity: Pleomorphic Hyalinizing Angiectatic Tumor (PHAT)
2017
Abstract Pleomorphic Hyalinizing Angiectatic Tumor (PHAT) is a rare benign lesion characterized by slow growth, infiltrative behavior and high rate of local recurrences. Only one case has been described in retroperitoneum, at renal hilum, but not involving pelvis or parenchyma. Here we present the first case of PHAT arising in the renal parenchyma. A nodular lesion in right kidney lower pole was diagnosed to a 61 year old woman. The patient underwent right nephrectomy. Microscopically, the lesion showed solid and pseudo-cystic components with hemorrhagic areas characterized by aggregates of ectatic blood vessels. Pleomorphic cells were characterized by large eosinophilic cytoplasm with irre…
The Small Size and Superficial Location Suggest That Laparoscopic Partial Nephrectomy Is the First Choice for the Treatment of Juxtaglomerular Cell T…
2021
BackgroundJuxtaglomerular cell tumor (JGCT) is a very rare disease, and surgical resection is the only possible way to cure this tumor. Open nephrectomy and partial nephrectomy have been reported to manage JGCTs with excellent results in the previous reviews. Laparoscopic surgery has been popularized in recent years, while critical issues associated with laparoscopic surgical management have been seldom reported. We summarized the JGCTs in our center to discover the optimal surgical management and its anatomic foundation.MethodsIn this retrospective study, we enrolled a total of 14 JGCT patients. All patients received surgeries and were followed up for up to 11 years. We mainly summarized t…
Hand-assisted laparoscopic living-donor nephrectomy versus open surgery: evaluation of surgical trauma and late graft function in 82 patients
2009
Abstract Objective We evaluated and quantified surgical trauma and late graft function in cases of hand-assisted laparoscopic living-donor nephrectomy (HALLDN) versus open living-donor nephrectom (OLDN). Methods This study is a retrospective nonrandomized single-center analysis. Between 1995 and January 2008, 82 patients with end-stage renal disease received kidney transplantations from living donors. Open living-donor nephrectomy was performed in 37 donors, and 45 underwent laparoscopic hand-assisted nephrectomy. Demographic data and perioperative and postoperative data, such as markers of acute phase (C-reactive protein; serum amyloid A) and biochemical markers of glomerular filtration (s…
Segmental Ureterectomy Versus Radical Nephroureterectomy in Older Patients Treated for Upper Tract Urothelial Carcinoma
2022
Introduction: The world population is ageing and surgical procedures for older patients are associated with higher perioperative morbidity and mortality rates than in younger patients. Segmental ureterectomy (SU) has been proposed as an alternative to radical nephroureterectomy (RNU) for selected upper tract urothelial carcinomas (UTUC), to reduce post-operative morbidity, and preserve renal function. The aim of this study was to compare RNU and SU in terms of post-operative complications, functional outcomes, and overall survival (OS) in older patients treated for UTUC. Materials and methods: Data of patients aged 75 years or older and treated for UTUC were included. The primary outcome wa…
Absolok® versus Hem-o-Lok® clips for renorrhaphy during partial nephrectomy for parenchymal renal tumors
2020
Background To compare perioperative and functional outcomes associated with renorrhaphy performed with two different types of clips (Absolok® vs. Hem-o-Lok®) in a contemporary series of patients who underwent partial nephrectomy. Methods Patients in whom Absolok® clips were used to perform haemostasis at the level of tumor bed or to block the running sutures during sliding-clip renorrhaphy (study group) were compared with a contemporary control group of patients in whom renorrhaphy was performed with Hem-o-Lok® clips. Both groups received the same surgical technique via an open or robot-assisted approach. Inner renorrhaphy was performed with one or more 3-0 (26 mm needle) monofilament runni…
Predicting positive surgical margins in partial nephrectomy: A prospective multicentre observational study (the RECORd 2 project)
2020
PURPOSE: to evaluate clinical predictors of positive surgical margins (PSMs) in a large multicenter prospective observational study and to develop a clinic nomogram to predict the likelihood of PSMs after partial nephrectomy (PN). MATERIALS AND METHODS: We prospectively evaluated 4308 patients who had surgical treatment for renal tumors between January 2013 and December 2016 at 26 urological Italian Centers (RECORd 2 project). Two multivariable logistic models were evaluated to predict the likelihood of PSMs. Center caseload was dichotomized using a visual assessment adjusted for several predictors of PSMs. A nomogram predicting PSMs was developed. RESULTS: Overall, 2076 patients treated wi…
Validation of the 2009 TNM Version in a Large Multi-Institutional Cohort of Patients Treated for Renal Cell Carcinoma: Are Further Improvements Neede…
2010
Background: A new edition of the TNM was recently released that includes modifications for the staging system of kidney cancers. Specifically, T2 cancers were subclassified into T2a and T2b ( 10 cm), tumors with renal vein involvement or perinephric fat involvement were classified as T3a cancers, and those with adrenal involvement were classified as T4 cancers. Objective: Our aim was to validate the recently released edition of the TNM staging system for primary tumor classification in kidney cancer. Design, setting, and participants: Our multicenter retrospective study consisted of 5339 patients treated in 16 academic Italian centers. Intervention: Patients underwent either radical or part…
Features Associated with Recurrence Beyond 5 Years After Nephrectomy and Nephron-Sparing Surgery for Renal Cell Carcinoma: Development and Internal V…
2014
Background: Approximately 10-20% of recurrences in patients treated with nephrectomy for renal cell carcinoma (RCC) develop beyond 5 yr after surgery (late recurrence). Objective: To determine features associated with late recurrence. Design, setting, and participants: A total of 5009 patients from a multicenter database comprising 13 107 RCC patients treated surgically had a minimum recurrence-free survival of 60 mo (median follow-up [FU]: 105 mo [range: 78-135]); at last FU, 4699 were disease free (median FU: 103 mo [range: 78-134]), and 310 patients (6.2%) experienced disease recurrence (median FU: 120 mo [range: 93-149]). Interventions: Patients underwent radical nephrectomy or nephron-…
Anastomotic Pseudoaneurysm Complicating Renal Transplantation: Treatment Options
2010
Introduction: Anastomotic pseudoaneurysm following renal transplantation is uncommon. Indications for repair, treatment options and outcomes remain controversial. Report: We present 6 renal transplant recipients with large anastomotic pseudoaneurysms. Five of the patients underwent open repair while one had a stent-grafting and delayed transplant nephrectomy for a ruptured pseudoaneurysm. A transplant nephrectomy was needed in all cases but one. Arterial reconstruction enabled limb salvage in all cases. One patient died of sepsis postoperatively. No patient presented late infection, failure of vascular reconstruction, nor pseudoaneurysm recurrence. Conclusions: Surgical excision of anastomo…
