Through a comprehensive review of the Mayo Clinic experience with patients who had Meckel diverticulum, we sought to determine which diverticula should be removed when discovered incidentally during abdominal surgery.Meckel occur so infrequently that most articles have reported either small series or isolated cases. From these limited series, various conclusions been without clearly indicating incidental removed.Medical records were reviewed 1476 found diverticulum surgery from 1950 2002....

BACKGROUND The authors evaluated sarcopenia as a predictor of cancer‐specific survival (CSS) and overall (OS) among patients with urothelial cancer the bladder undergoing radical cystectomy (RC). METHODS lumbar skeletal muscle index (SMI) 205 treated RC for between 2000 2007 was measured. Sarcopenia classified according to international consensus definitions (SMI < 55 cm 2 /m men 39 women). CSS OS were estimated using Kaplan‐Meier method compared log‐rank test. Variables associated...

The NCCN Guidelines for Bladder Cancer provide recommendations the diagnosis, evaluation, treatment, and follow-up of patients with bladder cancer other urinary tract cancers (upper tumors, urothelial carcinoma prostate, primary urethra). These Insights summarize panel discussion behind recent important updates to guidelines regarding treatment non–muscle-invasive cancer, including how treat in event a bacillus Calmette-Guérin (BCG) shortage; new roles immune checkpoint inhibitors non–muscle...

Bladder cancer, the sixth most common cancer in United States, is commonly of urothelial carcinoma histologic subtype. The clinical spectrum bladder divided into 3 categories that differ prognosis, management, and therapeutic aims: (1) non-muscle-invasive (NMIBC); (2) muscle invasive, nonmetastatic disease; (3) metastatic cancer. These NCCN Guidelines Insights detail recent updates to for Cancer, including changes fifth edition WHO Classification Tumours: Urinary Male Genital Tumours how...

We evaluate the association between severe skeletal muscle deficiency or sarcopenia, and disease progression, cancer specific mortality all cause in patients with localized renal cell carcinoma treated radical nephrectomy.The baseline lumbar index of 387 nephrectomy for nonmetastatic 2000 2010 was measured on preoperative computerized tomography. Sarcopenia classified according to gender consensus definitions as male-skeletal less than 55 cm(2)/m(2) female-skeletal 39 cm(2)/m(2)....

Radical cystectomy continues to be associated with a nonnegligible risk of perioperative death and all cause mortality in the years after surgery remains relatively high. We investigated comparative ability various comorbidity indices predict 5-year radical cystectomy.We evaluated 891 patients who underwent between 1994 2005.

Multiple definitions of biochemical recurrence for prostate cancer exist after radical prostatectomy, and variation continues in outcome reporting secondary treatment initiation. We reviewed long-term prostatectomy outcomes to assess the most appropriate specific antigen cut point that predicts future disease progression.We identified 13,512 patients with cT1-2N0M0 who underwent between 1987 2010. Single points 0.2, 0.3, 0.4 0.5 ng/ml or greater, as well confirmatory value 0.2 greater...

Robot-assisted radical prostatectomy has undergone rapid dissemination driven in part by market forces to become the most frequently used surgical approach management of prostate cancer. Accordingly, a critical analysis its volume-outcome relationship important health policy implications. Therefore, we evaluated association hospital robot-assisted volume with perioperative outcomes, and examined distribution procedure contextualize relationship.We identified 140,671 men who underwent from...
