Abstract Introduction: The prostatic urethral Lift (PUL) procedure offers a novel treatment for men with lower urinary tract obstructive symptoms (LUTS) secondary to benign prostatic hyperplasia (BPH). Most patients who seek LUTS/BPH treatment choose the intervention that offers the expectations of a significant improvement in quality of life and the least chance of short or long term morbidity. We report the results of a prospective, non-randomized study designed to further characterize the perioperative subject experience with the PUL procedure.
Materials and methods: The PUL procedure employs permanent implants to mechanically pull the prostatic lateral lobes apart. Subjects… More >

Abstract Introduction: The objective of this study was to evaluate the impact of hospital case volume on perioperative outcomes and costs of radical cystectomy (RC) after controlling for differences in patient case mix.
Materials and methods: The Maryland Health Services Cost Review Commission database was queried for patients who underwent an open RC between 2000 and 2011. Patients were divided into tertiles based on hospital case volume. Groups were compared for differences in length of intensive care unit (ICU) stay, length of total hospital stay, rate of in-hospital deaths and procedure-related costs.
Results: In total, 1620 patients… More >

Abstract Introduction: We evaluated whether the extent of lymphadenectomy at the time of radical cystectomy for non-muscle invasive bladder cancer (NMIBC) impacts recurrence free survival.
Materials and methods: We conducted an IRB approved retrospective analysis of patients with clinical NMIBC who underwent radical cystectomy from 1990-2010. Patients were stratified based on extent of lymph node dissection using total lymph node yield as a surrogate indicator of lymph node dissection extent, with cut off analyses performed at 0, 8, 10, and 20 nodes removed. Analyses of recurrence free survival (RFS) were performed using log-rank analysis and multivariate Cox… More >

Abstract Introduction: Ureteral stent placement is a key urologic procedure used to manage ureteral obstructions. It is usually performed under general anesthesia (GA) with its inherent risks. The objective was to evaluate safety, feasibility and tolerance of ureteral stent placement under local anesthesia (LA) in women.
Materials and methods: From January 2010 to January 2013, we prospectively and consecutively reviewed all female patients who had an urgent retrograde ureteral stent placement under LA. Only primary stent placements were included in the study. Pain was assessed after surgery by Visual Analog Scale (VAS) and pain and comfort assessment during… More >

Abstract Introduction: Renal functional decline after partial nephrectomy (PN) may be related to a variety of non-modifiable and modifiable factors, including ischemia time (IT) and modality. We sought to determine the impact of these factors on renal functional degeneration after PN.
Materials and methods: Multicenter retrospective analysis (n = 347) was performed, identifying patients who underwent open PN using warm, cold, and non-ischemic techniques. Primary outcome was development of de novo chronic kidney disease (CKD), (estimated glomerular filtration rate (eGFR) < 60 mL/min/1.73 m²), at 1 year follow-up. Univariate and multivariable analysis (MVA) were performed examining factors associated… More >

Abstract Introduction: With the increasing use of partial nephrectomy, cases of ipsilateral tumor recurrence will inevitably occur. We aimed to evaluate the efficacy and feasibility of laparoscopic radical nephrectomy (LRN) for a previously operated kidney, through a case-matched comparison with LRN in patients without prior renal surgery.
Materials and methods: Among 550 patients who underwent hand-assisted or standard LRN at our institution between August 1996 and January 2013, we identified patients who had prior laparoscopic or open surgical renal surgery. Each study patient was matched 1:2 with patients who had not had prior renal surgery. Matching was exact… More >

Abstract Introduction: Partial nephrectomy (PN) via open or minimally invasive (MI) techniques is the referent standard for managing renal cell carcinoma (RCC) whenever possible. Outcomes of MIPN in the obese patient population are incompletely defined. We investigate the feasibility of MIPN in obesity class I-III patients via comparison of surgical outcomes to those with a lower body mass index (BMI).
Materials and methods: The electronic medical records of 184 consecutive patients undergoing MIPN via laparoscopic (n = 109) or robotic (n = 75) techniques were reviewed. Patients were classified into the following patient cohorts stratified by BMI:… More >

Abstract Prostate leiomyomas are benign mesenchymal smooth muscle tumors devoid of glandular elements within the prostate or juxta-prostatic position. Leiomyomas develop in organs containing smooth muscle, including the kidney, bladder and seminal vesicle. Prostate leiomyomas are either a pure form or associatedwithbenignprostatehyperplasia,anddiagnosis is challenging, with defnitive identifcation relying on pathology. However, imaging techniques, such as MRI, have proven to be useful diagnostic tools. We report on a 57-year-old male with lower urinary tract symptomatology who was diagnosed with a large prostate leiomyoma and underwent an open radical cystoprostatectomy and ileal conduit urinary diversion.

Abstract Dual energy computed tomography (DECT) utilizes the material change in attenuation when imaged at two different energies to determine the composition of urinary calculi as uric acid or non-uric acid. We discuss a series of case reports illustrating DECT’s ability to provide immediate determination of uric acid versus non-uric acid calculi and facilitate more informed clinical decision-making. Further, these cases demonstrate a unique population of patients with ureteral stents and percutaneous nephrostomy tubes that benefit from DECT’s ability to create a virtual color contrast between an indwelling device and the stone material and thereby significantly More >

Abstract The Bricker ileal conduit has been the most popular urinary diversion technique following a radical cystectomy since the 1950s. The procedure typically provides a high quality of life for patients. However, stomal complications occur in 16%-65% of ileal conduit cases. We describe an easy technique to aid in the intussusception of a Bricker ileal conduit. This technique produces stomas with a height of 2 cm-3 cm consistently. In our experience, we have had excellent results when using this technique. More >
