Abstract Introduction: To investigate the trends in the performance of radical cystectomy (RC) versus partial cystectomy (PC) in the United States over the past 10 years and compare postoperative outcomes between two procedures.
Materials and methods: The data was captured from the Nationwide Inpatient Sample (NIS) 2001-2010 using the appropriate ICD-9-CM diagnosis and procedure codes. Patient sociodemographics, comorbidities and in-hospital complications after PC and RC were compared, taking into account some hospital characteristics. A chi-square analysis including a Cochran-Armitage trend test and a multivariable logistic regression analysis were employed.
Results: RC rate increased from 84.8% in 2001… More >

Abstract Introduction: Renal masses are commonly managed by partial nephrectomy (PN) or active surveillance (AS). We assessed the impact of patient demographics and clinical indices in determining treatment decisions of renal masses between these two options.
Materials and methods: We retrospectively reviewed our renal mass database to retrieve demographic and clinical records of patients who underwent immediate PN or entered a ≥12 month period of AS during February 1999 to May 2014. Age, gender, body mass index (BMI), Charlson Comorbidity Index (CCI) score, follow up time, tumor size, tumor location, renal invasion, creatinine, and estimated glomerular filtration… More >

Abstract Introduction: We examine the incidence and predictors of readmission after major urologic cancer surgery using a national, prospective-maintained database specifically developed to assess quality of surgical care.
Materials and methods: Patients undergoing major urologic cancer surgery (radical prostatectomy [RP], radical nephrectomy [RNx], partial nephrectomy [PNx]), radical cystectomy [RC]) in 2011 were identified using the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) using Current Procedural Terminology (CPT) codes. Those readmitted within 30 days after surgery were identified. Multivariable logistic regression models examined the association between patient characteristics and the odds of readmission.
Results: Overall,… More >

Abstract Introduction: To identify risk factors for PSA bounce (PSAb) and compare characteristics of prostate cancer patients treated with brachytherapy and external beam radiotherapy (EBRT).
Materials and methods: We identified 362 patients treated for low risk prostate adenocarcinoma (D’Amico criteria) with a follow up time of at least 36 months. Patients received either: 1) EBRT 76 Gy in 38 fractions (n = 58); 2) hypofractionated EBRT, 45 Gy in 9 once-weekly fractions (n = 74); 3) seed brachytherapy (n = 230). PSAb was defined as a rise ≥ 0.2 ng/mL with subsequent return to baseline within the first… More >

Abstract Introduction: Penile prosthesis implantation (PPI) is the definitive surgical treatment for erectile dysfunction (ED), yet it is often delayed for a variety of reasons. From commercial and Medicare claims data, we previously developed a tool for determining a patient’s likelihood of eventually receiving PPI. We validated this instrument’s utility by comparing cohorts receiving surgical (PPI) versus non-surgical ED management at a single institution.
Material and methods: The prediction model was based on a logistic regression incorporating claims data on demographics, comorbidities and ED therapy. A risk score is calculated from the model as the product of relative… More >

Abstract Introduction: To report the characteristics and anti-incontinence outcomes of men who fail to demonstrate incontinence on intubated urodynamics (UDS).
Materials and methods: From 2005 to 2013, the records of men who underwent UDS prior to artificial urinary sphincter (AUS) were reviewed. The histories, UDS, endoscopies, and anti-incontinence outcomes of men who failed to demonstrate incontinence on intubated UDS were recorded. In our UDS protocol, the urodynamic urethral catheter was removed and the UDS was repeated to elicit incontinence without the urethral catheter. The valsalva leak point pressure (VLPP) was obtained via the rectal catheter in these men.

Abstract Introduction: To evaluate the efficacy of transecting anastomotic urethroplasty (AU) and buccal mucosa graft (BMG) ventral onlay substitution urethroplasty (SU) in treating short bulbar urethral strictures.
Materials and methods: Sixty patients underwent either AU or SU for bulbar strictures of similar length with follow up of at least 12 months. Follow up included clinical history, uroflowmetry, and ultrasound post-void residuals (PVR) performed every 4 months for the first year and yearly thereafter.
Results: Out of 131 patients with short bulbar strictures, 40 were treated with BMG onlay SU and 20 had AU. Median follow up in the SU… More >

Abstract Introduction: Blunt abdominal trauma can result in injury to genitourinary (GU) organs. Children may be more susceptible to some GU injuries due to anatomic differences compared to adults. Mechanism of injury (MOI) has been thought to relate to both the likelihood and severity of GU injury in children, although this has not definitively been proven. Our purpose was to determine if MOI has any correlation to the severity of GU injury in children treated at our institution.
Materials and methods: We reviewed records of all pediatric blunt trauma patients presenting to our institution from January 2005-December 2010… More >

Abstract Recently, diagnoses of small renal masses and renal cell carcinoma (RCC) have increased due to the widespread use of radiographic imaging studies (computerized tomography, magnetic resonance imaging). It appears that biological factors such as obesity and tobacco use increase the risk for RCC. In general, small malignant renal masses are low stage and low grade. The management of asymptomatic renal masses is a surgical challenge since overtreatment of benign masses is not desired, especially for patients with complex medical comorbidities, elderly patients, and those with impaired renal function. Partial nephrectomy has been considered the gold More >

Abstract Our objective is to describe a novel presentation of subcutaneous penile insertion of foreign bodies. This is a practice performed globally and mostly has been reported outside of the United States. We present three cases of incarcerated males that implanted sculpted dominos into the penile subcutaneous tissue. The patients presented with erosion of the foreign bodies through the skin without evidence of infection. We believe that insertion of foreign bodies into penile subcutaneous tissue by incarcerated American males for sexual enhancement is more widespread than previously reported. Erosion is a novel presentation. More >

Abstract Inflammatory myofibroblastic tumor (IMT) of the kidney is a rare and benign condition often confused with renal malignancy based on clinical presentation and radiologic evaluation that has commonly been treated with nephrectomy. Utilizing renal mass biopsy to help diagnose and guide therapeutic intervention is increasing but has not been universally adopted to this point. We present a case of an incidentally found atypical renal mass in a 71-year-old female diagnosed as inflammatory myofibroblastic tumor of the kidney after core needle biopsy. This tumor was managed conservatively without surgical intervention and resolved spontaneously. More >

Abstract Benign multicystic mesothelioma (BMM) is a benign intra-abdominal lesion that generally occurs in women in their reproductive years. A urachal cyst occurs when the epithelial-lined urachal canal fails to completely obliterate. We report a case of a 38-year-old female presenting with abdominal pain found to have a lesion highly suspicious for a urachal cyst. On pathologic evaluation the lesion was identified as a BMM. This is the first report of BMM presenting as a lesion suspected to be a urachal cyst. More >
