OBJECTIVES To present our experience with the management of renal artery pseudoaneurysms following laparoscopic partial nephrectomy (LPN). METHODS Our bi-institutional LPN database of 259 patients from July 2001 to April 2008 was queried for patients diagnosed with a postoperative renal artery pseudoaneurysm. Demographic data, perioperative course,(More)
OBJECTIVES To examine the transition to robot-assisted laparoscopic partial nephrectomy (RALPN) from pure laparoscopic partial nephrectomy (LPN) and investigate the learning curve (LC). RALPN has emerged as a minimally invasive alternative to nephron-sparing surgery. METHODS A total of 150 consecutive patients were identified who underwent LPN or RALPN in(More)
OBJECTIVE To validate the Guy's stone score (GSS) using preoperative computed tomography (CT) and to assess its inter-rater concordance and association with rigorous definitions of stone clearance. METHODS The preoperative CT scans of 166 consecutive percutaneous nephrolithotomy (PCNL) patients treated by a single surgeon were independently reviewed by 2(More)
OBJECTIVES To analyze pathological and short-term oncological outcomes in men undergoing open and minimally-invasive radical prostatectomy (MIRP) for high-risk prostate cancer (HRPC; prostate-specific antigen level [PSA] >20 ng/mL, ≥ cT2c, Gleason score 8-10) in a contemporaneous series. PATIENTS AND METHODS In total, 913 patients with HRPC were(More)
BACKGROUND AND PURPOSE Robot-assisted laparoscopic partial nephrectomy (RALPN) is supplanting traditional laparoscopic partial nephrectomy (LPN) as the technique of choice for minimally invasive nephron-sparing surgery. This evolution has resulted from potential clinical benefits, as well as proliferation of robotic systems and patient demand for(More)
PURPOSE While percutaneous nephrostolithotomy is the standard of care for renal stones greater than 2 cm, recent studies have shown that staged ureteroscopy/holmium laser lithotripsy may be a reasonable option. Stones 2 to 3 cm may be amenable to ureteroscopy as well as to 1-stage treatment based on their intermediate size. We compared clinical outcomes and(More)
BACKGROUND AND PURPOSE Percutaneous nephrostolithotomy (PCNL) is the current standard of care for management of large renal stones (>2 cm). Recent studies have evaluated flexible ureterorenoscopy (URS)/holmium laser lithotripsy as an alternative treatment for patients with contraindications to or preference against PCNL. Stones in an intermediate size range(More)
BACKGROUND AND PURPOSE Our present understanding of the effect of robotic surgery and surgical volume on the cost of radical prostatectomy (RP) is limited. Given the increasing pressures placed on healthcare resource utilization, such determinations of healthcare value are becoming increasingly important. Therefore, we performed a study to define the effect(More)
OBJECTIVES To perform a multi-institutional study to characterize CT-detected complications after PNL. Computed tomography (CT) is commonly performed after percutaneous nephrolithotomy (PNL). One benefit of this imaging modality is the detection of procedure-related complications. Presently, the incidence of such complications is not well-defined. (More)
PURPOSE Patients with acute flank pain or kidney pain are most commonly evaluated in the emergency department with computerized tomography. Currently our understanding of radiographic practice patterns in emergency imaging for flank pain is limited. We characterized the use of conventional radiography (x-ray), ultrasound and computerized tomography in the(More)
