Article Abstract
Surgical extirpation remains the most effective therapy for renal cell carcinoma. The surgical management of renal masses has evolved away from radical nephrectomy and now includes nephron-sparing surgery for small tumors. Nephron-sparing surgery has similar cure rates and does not appear to compromise cancer control. As the detection of small renal masses by widespread abdominal imaging continues to increase, so will the demand for minimally invasive nephron-sparing procedures. Despite progress in surgical techniques, laparoscopic partial nephrectomy remains a technically challenging procedure. In this review, we discuss the challenges and recent advances in laparoscopic partial nephrectomy and other minimally invasive approaches to renal masses.
Background: Uterine carcinosarcoma (UCS), or malignant mixed Müllerian tumor, is a cancer that include both carcinomatous and sarcomatous components, resembling endometrial carcinoma. A 55-year-old woman was admitted to the hospital with postmenopausal vaginal bleeding. Gross examination of the specimen revealed brittle tissue in the fundus and the left wall of the endometrium.
Background: Thrombotic microangiopathy (TMA) is a rare, life-threatening disorder characterized by microangiopathic hemolytic anemia, thrombocytopenia, and end-organ damage. Atypical hemolytic uremic syndrome (aHUS) is even less common, comprising less than 10% of hemolytic uremic syndrome (HUS) cases. aHUS in postpartum is associated with poor maternal outcomes, with the majority of cases resulting in end-stage renal disease.
The Senhance robotic system (Asensus Surgical, Durham, NC, USA) is an innovative platform for minimally invasive surgery. It enables surgeons to perform precise and cost-effective procedures using reusable instruments and has advanced features such as haptic feedback and eye-tracking camera control. Herein, we present the first application of the "double bipolar method" (DBM) in a Senhance-assisted laparoscopic partial cystectomy utilizing 3 mm Maryland bipolar instruments.
Study Question: How do endometriosis diagnoses and subtypes reported in administrative health data compare with surgically confirmed disease?
Summary Answer: For endometriosis diagnosis, we observed substantial agreement and high sensitivity and specificity between administrative health data-International Classification of Diseases (ICD) 9 codes-and surgically confirmed diagnoses among participants who underwent gynecologic laparoscopy or laparotomy.
What Is Known Already: Several studies have assessed the validity of self-reported endometriosis in comparison to medical record reporting, finding strong confirmation. We previously reported high inter- and intra-surgeon agreement for endometriosis diagnosis in the Endometriosis, Natural History, Diagnosis, and Outcomes (ENDO) Study.
Background: Nephrogenic adenoma (NA) is a rare benign tumor that can develop at any site of the urinary system, with the bladder being the most common, followed by the urethra, ureters, renal pelvises, etc. Currently, it is unclear what the pathogenesis of NA is. This study discussed a rare case of malignant transformation from NA to mesonephric adenocarcinoma of the bladder.
