The long-term survival outcome of sporadic bilateral renal cell carcinoma and optimization of surgical treatment: a large-scale population-based cohort study.

Sporadic bilateral renal cell carcinoma (BRCC) is a rare situation of RCC. The treatment for BRCC is controversial and there is a lack of authoritative guidelines about the management of BRCC. Patients diagnosed with sporadic BRCC between 2004 and 2020 were identified from Surveillance, Epidemiology, and End Results (SEER) database.

Impact of race and payor status on patterns of utilization of partial and radical nephrectomy in patients with renal cell carcinoma in California.

Background: Prospective trials have shown similar outcomes with partial nephrectomy (PN) in patients with localized renal cell carcinoma (RCC), and multiple studies suggest increasing the use of the technique. We hypothesize that patients who stem from minority groups, as well as Medicare and Medical, have less access to this specialized procedure and, therefore, have a higher rate of radical nephrectomy (RN).

Methods: We interrogated the California Office of Statewide Health Planning and Development (OSHPD) database, which collects information from all inpatient admissions, emergency room visits and inpatient/outpatient procedures in the state.

Application value of contrast-enhanced ultrasound in the preoperative evaluation of renal cell carcinoma histological classification and RENAL score.

Background: Renal cell carcinoma (RCC), the most common malignant renal tumor, is primarily treated by surgical resection, including radical nephrectomy (RN) and partial nephrectomy (PN). At present, the choice of surgery mainly depends on the comprehensive evaluation of patients' clinical data, including histological classification, such as clear cell renal cell carcinoma (ccRCC) and non-clear cell renal cell carcinoma (nccRCC), and RENAL (radius, exophytic/endophytic, nearness, anterior/posterior, and location) score. Compared with biopsy and contrast-enhanced computed tomography (CECT), contrast-enhanced ultrasound (CEUS) is safer and less invasive.

Evaluating the necessity of postoperative day 1 labs following laparoscopic radical nephrectomy (LRN).

Background: Standard postoperative care following laparoscopic radical nephrectomy (LRN) typically includes routine blood tests. Recent studies have assessed the safety of omitting routine postoperative labs in minimally invasive surgeries to reduce hospital costs. Our primary objective was to evaluate if routine postoperative day 1 (POD1) labs were necessary following LRN.

Machine learning models predict the progression of long-term renal insufficiency in patients with renal cancer after radical nephrectomy.

Background: Chronic Kidney Disease (CKD) is a common severe complication after radical nephrectomy in patients with renal cancer. The timely and accurate prediction of the long-term progression of renal function post-surgery is crucial for early intervention and ultimately improving patient survival rates.

Objective: This study aimed to establish a machine learning model to predict the likelihood of long-term renal dysfunction progression after surgery by analyzing patients' general information in depth.

Metaverse surgical planning for robotic surgery: preliminary experience and users' perception.

Background: The 3D models' use for surgical planning has recently gained an ever-wider popularity, in particular in the urological field. Different ways of fruition of this technology have been evaluated over the years. Today, new technological developments allow us to enjoy 3D models in the metaverse.

Renal PEComa in a young male: A case report and insights from the literature.

Perivascular epithelioid cell tumors (PEComas) are rare mesenchymal neoplasms, commonly found in the uterus and retroperitoneum. Renal PEComas are exceedingly rare, often posing diagnostic challenges due to their resemblance to renal cell carcinoma (RCC) on imaging. We present the case of an 18-year-old male who presented with non-specific symptoms of fever, chills, and shivering.

The Current State of the Diagnoses and Treatments for Clear Cell Renal Cell Carcinoma.

Clear cell renal cell carcinoma is the most common form of kidney cancer, accounting for 75% of malignant kidney tumors, and is generally associated with poor patient outcomes. With risk factors including smoking, obesity, and hypertension, all of which have a high prevalence in the United States and Europe, as well as genetic factors including tuberous sclerosis complex and Von Hippel-Lindau syndrome, there is an increasing need to expand our present understanding. The current clear cell renal cell carcinoma knowledge is outdated, with obsolete diagnostic criteria and moderately invasive surgical treatments still prevailing, partially ascribed to its resistance to chemotherapy and radiation therapy.

Coexistence of tubulocystic renal cell carcinoma and polycythemia vera: A rare case report.

Tubulocystic Renal Cell Carcinoma (TC-RCC) and Polycythemia Vera (PV) are both infrequent medical conditions. TC-RCC was recognized as a distinct subtype of kidney cancer by the World Health Organization in 2016, while PV is a rare myeloproliferative neoplasm distinguished by the excessive production of red blood cells. The coexistence of these two conditions is exceptionally uncommon and lacks comprehensive documentation.

Predictive Value of the Platelet-Lymphocyte Ratio for Intravesical Recurrence After Radical Nephroureterectomy: A Retrospective Study.

Objective: The aim of this study was to evaluate the impact of preoperative platelet lymphocyte ratio (PLR) on the prognosis of patients after radical nephrectomy (RNU).

Methods: We retrospectively analyzed clinical data from 226 patients without a history of bladder cancer who underwent RNU at Beijing Chaoyang Hospital, Capital Medical University between January 2009 and December 2020. Patients were stratified into two groups (A low PLR group (n = 174) and a high PLR group (PLR ≥ 169.

Smooth Muscle and Adenoma-Like Renal Tumor (SMART)- A Rare Biphasic Renal Tumor with a Review.

Smooth muscle and adenoma-like renal tumor (SMART) is a biphasic tumor composed of cytologically bland stromal and epithelial components. It has many histopathological mimickers. A 57-year-old man presented with a left renal mass.

Is Frequent Imaging Necessary? Impact of Computed Tomography During Follow-up After Surgical Treatment for Nonmetastatic Renal Cell Carcinoma: A Systematic Review.

Background And Objective: Current guidelines on radiological follow-up (FU) for patients after treatment for nonmetastatic renal cell carcinoma (RCC) are not based on robust evidence. This review aims to evaluate whether the 2022 European Association of Urology (EAU) guidelines are noninferior, in terms of recurrence and (overall) survival, to a higher imaging frequency of computed tomography (CT) of the chest and abdomen.

Methods: A literature search of relevant search machines (PubMed/Medline and EMBASE) was performed up to May 29, 2024.

Atypical carcinoid of the primary kidney with retroperitoneal metastasis 15 years later: A case report and literature review.

Primary renal neuroendocrine tumors (NETs) are extremely rare among renal malignancies. According to pathological manifestations, carcinoid can be divided into four types: typical carcinoid, atypical carcinoid, large cell and small cell neuroendocrine carcinoma. Primary or secondary retroperitoneal carcinoid is even rarer than renal carcinoid.

Asystematic review and meta-analysis of clinical prognostic factors linked to extravesical recurrence after radical nephroureterectomy to treat upper tract urothelial carcinoma.

Objective: Numerous studies have investigated predictors of intravesical recurrence following radical nephrectomy (RNU) in patients with upper urinary tract uroepithelial carcinoma (UTUC). In contrast, extravesical recurrence (EUR) has received less focus. Consequently, this study aims to evaluate the significant predictors of EUR after RNU through a systematic review of the literature and a meta-analysis.

Case report: A rare case of renal tuberculosis combined with bladder cancer.

We report a case of renal tuberculosis combined with bladder cancer. The patient was a 57-year-old man with no history of tuberculosis who presented with hematuria and signs of urinary tract irritation. Computed tomography (CT) showed florid, bowel-filling calcifications at the level of the right renal hilum, multiple hyperdense shadows from the right renal pelvis to the ureter, and left pyelo-ureteral effusion.

Retrograde aortic dissection encountered amidst nephrectomy for renal cell carcinoma with IVC thrombus - a case report.

Background: Management of RCC with IVC thrombus can be surgically challenging, particularly when the tumour thrombus extends above the diaphragm. Cardiopulmonary bypass is often employed to aid surgical removal of the tumour in such cases.

Case Presentation: We detail an instance of 67-year-old Male patient suffering from RCC with IVC thrombus, with the tumour thrombus extending into the right atrium, who developed on-table retrograde type A aortic dissection amidst the surgical procedure, thereby precluding cardiopulmonary bypass.
