Objective: Our objective was to evaluate 30-day readmission, 12-month prolapse recurrence, and complications after apical surgeries in older women.
Methods: A retrospective cohort study was conducted using 2002-2011 Medicare data in women 65 years or older who underwent abdominal sacrocolpopexy with synthetic mesh, vaginal uterosacral, or sacrospinous colpopexy with 12 months follow-up. Vaginal mesh procedures were excluded.
Background: Bacillus Calmette-Guérin (BCG) is the reference standard treatment for patients with high-grade, non-muscle-invasive bladder cancer (NMIBC). We previously described noncompliance with guidelines for BCG use in patients with high-risk disease. In the current study, we sought to characterize how the number of endoscopic resections of bladder tumors affects BCG utilization using population-level data.

As neither the association of recurrences with survival nor the subsequent aggressive treatment in individuals with recurrent high-grade non-muscle-invasive bladder cancer has ever been quantified, we sought to determine whether the increasing number of recurrences is associated with higher subsequent treatment and mortality rates.
Methods: Using linked Surveillance, Epidemiology, and End Results-Medicare data, we identified subjects with recurrent high-grade, non-muscle-invasive disease diagnosed in 1992 to 2002 and followed up until 2007.
Objective: We sought to determine the prevalence of initial computed tomography (CT) utilization and to identify regions in the United States where CT is highly used as the first imaging study for children with nephrolithiasis.
Methods: We performed a cross-sectional study in 9228 commercially insured children aged 1 to 17 years with nephrolithiasis who underwent diagnostic imaging in the United States between 2003 and 2011. Data were obtained from MarketScan, a commercial insurance claims database of 17,827,229 children in all 50 states.
Importance: Shock wave lithotripsy (SWL) and ureteroscopy (URS) account for more than 90% of procedural interventions for kidney stones, which affect 1 in 11 persons in the United States. Efficacy data for SWL are more than 20 years old. Advances in URS, along with emerging evidence of reduced efficacy of modern lithotripters, have created uncertainty regarding the comparative effectiveness of these 2 treatment options.
View Article and Find Full Text PDFBackground: Patients with bladder cancer are apt to develop multiple recurrences that require intervention. The recurrence, progression, and bladder cancer-related mortality rates were examined in a cohort of individuals with high-grade non-muscle-invasive bladder cancer.
Methods: Using linked Surveillance, Epidemiology, and End Results (SEER)-Medicare data, subjects were identified who had a diagnosis of high-grade, non-muscle-invasive disease in 1992 to 2002 and who were followed until 2007.
Background: Although there is level I evidence demonstrating the superiority of intravesical therapy in patients with bladder cancer, surveillance strategies are primarily founded on expert opinion. The authors examined compliance with surveillance and treatment strategies and the pursuant impact on survival in patients with high-grade disease.
Methods: Using linked Surveillance, Epidemiology, and End Results (SEER)-Medicare data, the authors identified subjects with a diagnosis of high-grade, non-muscle-invasive disease between 1992 and 2002 who survived 2 years and did not undergo definitive treatment during that time.
Background: Clinical practice guidelines for the management of patients with bladder cancer encompass strategies that minimize morbidity and improve survival. In the current study, the authors sought to characterize practice patterns in patients with high-grade non-muscle-invasive bladder cancer in relation to established guidelines.
Methods: Surveillance, Epidemiology and End Results (SEER)-Medicare-linked data were used to identify subjects diagnosed with high-grade non-muscle-invasive bladder cancer between 1992 and 2002 who survived at least 2 years without undergoing definitive treatment (n = 4545).
Background: The rate of continent urinary diversion after radical cystectomy for bladder cancer varies by patient and provider characteristics. Demonstration of equivalent complication rates, independent of diversion type, may decrease provider reluctance to perform continent reconstructions. The authors sought to determine whether continent reconstructions confer increased complication rates after radical cystectomy.
View Article and Find Full Text PDFBackground: Most urologists specializing in the management of patients with bladder cancer consider continent urinary diversion the reconstructive technique that affords the best quality of life after radical cystectomy. The authors sought to evaluate factors that predict reconstructive technique after radical cystectomy.
Methods: Using linked data from Medicare and the National Cancer Institute's (NCI) Surveillance, Epidemiology, and End Results (SEER) program, 3611 subjects were identified who underwent radical cystectomy for bladder cancer between 1992 and 2000.
Purpose: The burden of urological diseases on the American public is immense in human and financial terms but it has been under studied. We undertook a project, Urologic Diseases in America, to quantify the burden of urological diseases on the American public.
Materials And Methods: We identified public and private data sources that contain population based data on resource utilization by patients with benign and malignant urological conditions.
