BACKGROUND Transperitoneal robot-assisted laparoscopic prostatectomy (RALP) urethrovesical anastomosis is a critical step. Although the prevalence of urine leaks ranges from 4.5% to 7.5% at high-volume RALP centers, urine leaks prolong catheterization and may lead to ileus, peritonitis, and require intervention. Barbed polyglyconate sutures maintain running(More)
OBJECTIVES This study sought to determine whether nitric oxide-mediated vasodilation is abnormal in patients with non-insulin-dependent diabetes mellitus. BACKGROUND Multiple investigations, both in experimental models and in patients with insulin-dependent diabetes mellitus, demonstrate impaired endothelium-dependent vasodilation. Decreased availability(More)
BACKGROUND Endothelial function is impaired in patients with diabetes mellitus. However, the factors contributing to this defect are currently unknown. Hyperglycemia attenuates endothelium-dependent relaxation in normal rabbit arteries in vitro and rat arterioles in vivo. Accordingly, this study examined the effect of acute hyperglycemia on(More)
BACKGROUND Previous studies demonstrate that androgen-deprivation therapy (ADT) with gonadotropin-releasing hormone (GnRH) agonists and orchiectomy for prostate cancer (PCa) is associated with cardiovascular disease. However, few studies have examined its effect on the peripheral vascular system. OBJECTIVE To study the risk of peripheral artery disease(More)
OBJECTIVE To evaluate contemporary national practice pattern trends in the use of thermal ablation (radiofrequency ablation and cryoablation) in the management of stage I renal cell carcinoma (RCC), and the factors that lead to using thermal ablation (TA) vs partial (PN) or radical nephrectomy (RN) in the United States. METHODS Within the Surveillance,(More)
We present 19 cases of a previously undescribed myxoid tumor of the anterior tongue. These lesions occurred in nine women and 10 men aged 9 to 78 years (median, 32 years). Most tumors were seen as slow growing, painless nodules in the anterior dorsal tongue. The duration of growth ranged from a few months to 10 years. All tumors were treated by surgical(More)
BACKGROUND The advanced age and comorbidities often associated with bladder cancer patients creates a difficult scenario regarding further management. Robotic-assisted laparoscopic radical cystectomy (RALRC) has had favorable results as a minimally invasive treatment option. We studied perioperative outcomes of RALRC in octogenarians to discern if there is(More)
PURPOSE The aim of this study was to assess incidence, risk factors, and recurrence rates for conservative and surgical management of small bowel obstruction. METHODS Retrospective chart review was conducted of 329 patients accounting for 487 admissions with small bowel obstruction. Data were obtained from the institutional database and patient charts.(More)
Basal cell adenocarcinoma is a recently defined category of salivary gland neoplasms. As the terminology implies, this group of tumors has many histopathologic features that are similar to the more well-known basal cell adenomas. To better characterize these tumors, 23 basal cell adenocarcinomas were reviewed and compared with 11 basal cell adenomas with(More)
BACKGROUND Large prostate size, median lobes, and prior benign prostatic hyperplasia (BPH) surgery may pose technical challenges during robot-assisted laparoscopic prostatectomy (RALP). OBJECTIVE To describe technical modifications to overcome BPH sequelae and associated outcomes. DESIGN, SETTINGS, AND PARTICIPANTS A retrospective study of prospective(More)
