235 Morbidity and mortality after benign prostatic hyperplasia surgery: Data from the national surgical quality improvement program

RESULTS: 484 patients had open or laparoscopic UOS, with 200 (41%) classified as high risk for VTE by CRSs. The rates of VTEs and median times to VTE were 6% and 74 days in Group 1, 13% and 44 days in Group 2, 15% and 40 days in Group 3, and 23% and 11 days in Group 4. Adjusted hazard ratios for VTE are shown in Table 1. Group 1 had no VTE’s or fatal pulmonary embolisms in the first 30 days after UOS. Bleeding and lymphocele rates were 0% and 2% in Group 1, 0% and 4% in Group 2, 3% and 3% in Group 3, 0% and 0% in Group 4. Complications were considered Clavien grades II-IIIa. CONCLUSIONS: VTE risk is lowest in patients who receive clinical protocol prophylaxis with EDP. Risk of VTE remains elevated for at least 90 days following UOS. A clinical VTE prevention protocol using perioperative prophylaxis and EDP is effective and safe in reducing VTE risk in UOS patients.

625 Predictors of admission in patients presenting to the emergency department with urinary tract infection

Purpose Previous studies examining the management of urinary tract infections (UTI) showed marked variability in the economical burden of care, with a tenfold increase in costs when patients require admission to the hospital. We sought to examine the patient and emergency department (ED) characteristics associated with hospitalization in patients presenting to the ED with UTI.

V13 ROBOTIC INFERIOR VENA CAVA THROMBECTOMY

Renal cell carcinoma (RCC) has a natural tendency of progression from the kidney along its route of venous drainage, into the inferior vena cava (IVC) in 4–10% of patients. Radical nephrectomy (RN) with tumor thrombectomy is the standard of care for these difficult cases. Even such complex operative procedures were conducted in an open fashion, potential fatal complications caused by bleeding or embolism may occur. Open surgery requires a big abdomen incision associated with slow recovery. With the development of laparoscopy and robotic technology in recent years, several centers had reported successful experience in laparoscopic IVC thrombectomy (IVCTE). However, laparoscopic IVCTE is extremely challenging and technically demanding, even for experienced laparoscopic surgeons. Surgical robotic equipment has been increasingly used in intricate laparoscopic procedures and might facilitate application of minimally invasive surgical techniques in such challenging surgeries. We performed robotic IVC thrombectomy (R-IVCTE) since 2013. Detailed techniques for R-IVCTE of different sides (left or right RCC) are compared and described below.
