Abstract Introduction: Renal trauma occurs in approximately 1%-5% of all trauma cases. Improvements in imaging and management over the last two decades have caused a shift in the treatment of this clinical condition.
Materials and methods: A systematic search of PubMed was performed to identify relevant and contemporary articles that referred to the management and evaluation of renal trauma.
Results: Computed tomography remains a mainstay of radiological evaluation in hemodynamically stable patients. There is a growing body of literature showing that conservative, non-operative management of renal trauma is safe, even for Grade IV-V renal injuries. If surgical exploration is More >

Abstract Introduction: The diagnosis and subsequent management of bladder cancer often involves transurethral resection of bladder tumor (TURBT). Risks of TURBT include perioperative complications such as bleeding, pain and perforation. We aimed to determine TURBT complication rates and risk factors in a contemporary series.
Materials and methods: From 2002 to 2011, 505 patients underwent TURBT either for suspected bladder cancer or during follow up at a single institution. Baseline patient characteristics and complications within 2 weeks of surgery were extracted from the electronic medical record for all TURBTs. Patient and tumor characteristics were evaluated for associations with complication… More >

Abstract Introduction: Circumcision is the most common surgical procedure performed worldwide. However, there is a dearth of literature regarding medical indications for adult circumcisions. Here, we describe our experience with adult circumcision and contemporary demographics, indications and complications.
Materials and methods: We reviewed all circumcisions performed in our institution between July 2008 and January 2015. Patient demographics, procedure indications and postoperative complications were recorded, and patients were grouped by age as either less than 50 years old or 50 years and older.
Results: A total of 202 charts were reviewed. The most common indications for circumcision were phimosis (46.5%), More >

Abstract Introduction: To report long term toxicity and efficacy of patients with intermediate risk prostate cancer treated with moderate hypofractionated radiotherapy (HypoRT).
Materials and methods: We studied the first consecutive 100 men with intermediate risk (stage T2b-T2c, or PSA=10-20ug/L, or Gleason score=7) adenocarcinoma of the prostate treated between October 2002 and May 2010 in our institution with moderate HypoRT. Patients were treated using three-dimensional conformal HypoRT to a dose of 66 Gy in 22 daily fractions prescribed to the isocenter. Androgen suppression was not given to any patient. A uniform 7mm margin was created around the prostate for… More >

Abstract Introduction: Up to 50% of patients will have disease reclassification while on active surveillance (AS) for their prostate cancer. Determining which patients will have reclassification that will impact their survival is difficult. We investigated clinicopathologic factors associated with disease reclassification and differences in both overall and metastasis free survival between those treated and those remaining on AS.
Materials and methods: We performed a retrospective review of patients who were enrolled in an AS protocol between 1994 and 2000. Inclusion criteria for AS were: < cT2a disease, PSA < 10 ng/mL, < 50% of single core involvement, and… More >

Abstract Introduction: The treatment of bilateral renal and/or ureteric stones can be challenging due to concerns about its safety and efficacy compared to staged ureteroscopy. This review evaluates the current evidence to look at the outcomes of bilateral simultaneous ureteroscopy (BS-URS) for urinary stone disease.
Material and methods: A systematic review using studies identified by a literature search between January 1990 and August 2013. All English language articles reporting on outcomes of BS-URS for urolithiasis were included. Two reviewers independently extracted the data from each study.
Results: A total of seven studies (312 patients) were identified with a mean… More >

Abstract Introduction: To compare surgical complications and tyrosine kinase inhibitor (TKI)-toxicities in patients who underwent primary cytoreductive nephrectomy (CN) followed by adjuvant TKI therapy versus those who underwent neoadjuvant TKI therapy prior to planned CN for metastatic renal cell carcinoma (mRCC).
Materials and methods: Two-center retrospective analysis. Sixty-one mRCC patients underwent TKI therapy with sunitinib between July 2007 to January 2014. Patients were divided into three groups: primary CN followed by adjuvant TKI (n = 27, Group 1), neoadjuvant TKI prior to CN (n = 21, Group 2), and primary TKI alone (no surgery, n = 13, Group… More >

Abstract Cardiac complications following surgery can be devastating especially if it is unrecognized. We present a case of a stress-induced cardiomyopathy that occurred in postoperative period following a robotic radical cystectomy and urinary diversion. While most cases of stress-induced cardiomyopathy, also known as Takotsubo cardiomyopathy, are transient and with little to no long term clinical effects, a small number of patients can develop severe complications. This has not been reported in urologic literature and the unique characteristics of this cardiac condition are reviewed. More >

Abstract Ureterosciatic hernias (USH) are a rare entity and to date there have been limited case reports detailing their presentation, diagnosis, and management. Until recently, repair of ureterosciatic hernias has been performed via open, endoscopic, or purely laparoscopic approaches. We present the second known published case of a robotic approach to the USH repair with detailed outline of the surgical technique accompanied by video recording from the operative procedure. More >

Abstract Tandem cuff artificial urinary sphincter (AUS) is a well-accepted treatment modality for refractory urinary incontinence following prostatectomy. We present a unique case of a 60-year-old male who experienced spontaneous urethral perforation between tandem AUS cuffs following a strong valsalva maneuver. The patient was treated with immediate AUS explant and transcorporal single cuff placement several months later. More >

Abstract Iatrogenic ureteral injuries are rare and must be accurately identified to minimize the risk for additional complications. Anterior lumbar interbody fusion (ALIF) is a valuable technique utilized in spine surgery, with its own unique set of complications. For example, retroperitoneal fluid collections following ALIF surgery are rare and may result in back pain, radicular pain, nausea, and even death. It is important to rapidly identify the nature of the fluid collection to clarify appropriate management options. The purpose of this case report is to present a differential diagnosis for a delayed presentation of an extremely… More >

Abstract Prostate cancer has a substantial heritable component, which is often under-appreciated in the urologic community. Inherited prostate cancer which may account for up to 10% of cases has been associated with genetic mutations which are also linked with other hereditary cancer syndromes. Therefore, family history indicating inherited prostate cancer predisposition may extend beyond prostate cancer to include other cancers such as breast, ovarian and others. Genetic counseling and genetic testing guidelines for prostate cancer are slowly emerging, which emphasizes the need for urologists and other providers involved in the care of prostate cancer patients to More >

Abstract Introduction: The aim of our study is to compare two different surgical procedures, lymphatic vessels and arterioles sparing microsurgical inguinal varicocelectomy (LASMIV) without delivery of the testis and LASMIV with delivery of the testis and ligature of collateral and gubernacular veins.
Materials and methods: Seventy adolescents suffering from varicocele and reduction of the ipsilateral testicular volume greater than 20% were prospectively assigned to two homogenous groups according to age and Tanner stage. The patients, operated from 2008 to 2013, were randomized to undergo either LASMIV without delivery of the testis or LASMIV with delivery and ligature of… More >
