Abstract Introduction: Active surveillance for prostate cancer is a therapeutic option which is gaining more popularity. Implicit in this approach is careful monitoring to identify those with progression. Criteria for placing patients on active surveillance vary but generally include Gleason sum of 6 or less, prostate-specific antigen (PSA) less than 20, and a small volume of cancer in the biopsy specimen. We review our experience with active surveillance in a veteran population.
Materials and methods: We conducted a retrospective review of patients from the Kansas City Veterans Affairs (KCVA) who met the requirements for active surveillance (Gleason sum… More >

Abstract Introduction: Level 1 evidence demonstrates the benefit of postoperative radiotherapy (PORT) for pT3 disease and positive margins. The role of androgen deprivation therapy (ADT) after PORT remains to be defined from results of ongoing randomized trials. This study was undertaken to determine the factors influencing the current use of ADT after PORT amongst Canadian radiation oncologists.
Methods: An institutional survey was emailed to the Genito-urinary Radiation Oncologists Group of Canada (GUROC), designed to assess the likelihood of prescribing ADT in early and delayed PORT scenarios with variations in disease prognosticators. Analysis used descriptive statistics.
Results: Majority (94%) do… More >

Abstract Introduction: The purpose of this study was to evaluate the utility of prostate-specific antigen (PSA) screening for prostate cancer after subcapsular prostatectomy.
Materials and methods: Data from 41 consecutive patients who underwent subcapsular prostatectomy at a single institution over a 15 year period were collected retrospectively. Patients were categorized into benign and malignant groups based on a diagnosis of prostate cancer identified in the surgical specimen or during subsequent follow up. Collected data included patient age, preoperative and postoperative PSA values, prostate volume determined by surgical specimen weight, and pathologic diagnosis. Preoperative and postoperative PSA velocities were… More >

Abstract Introduction: This was a prospective, randomized clinical trial to compare the safety, efficacy, and medium-term durability of holmium laser enucleation of the prostate (HoLEP) combined with mechanical morcellation versus standard transurethral resection of the prostate (TURP) for the surgical treatment of patients with bladder outlet obstruction due to benign prostatic hyperplasia (BPH). The patients had prostates that were greater than 30 g and less than 100 g and were followed for 1 year.
Patients and methods: From April 2008 to December 2009, 80 consecutive patients with lower urinary tract obstruction (LUTS) due to BPH were randomized to… More >

Abstract Introduction: Helical tomotherapy (HT) is an innovative approach to the delivery of intensity-modulated radiation therapy which combines the imaging elements of helical computed tomography (CT) with megavoltage linear accelerator treatment. The purpose of this report is to describe our experience with the clinical implementation of HT for genitourinary malignancies.
Materials and methods: All patients treated with a primary genitourinary malignancy were included in this study cohort. Descriptive statistics for various demographic and treatment-related parameters such as patient age, primary site of disease, site of radiotherapy, goal of treatment, dose/fractionation, immobilization and clinical trial enrolment were calculated.
Results: A… More >

Abstract Introduction: The detection rate of incidental renal masses is increasing. Historically these masses have been treated with extirpative surgery. Hence, there is little information on the growth rate, metastatic potential, and natural history of renal tumors. Through active surveillance, we study the natural history of renal masses and determine their growth rate and risk for metastasis.
Materials and methods: From 1997 to 2007, active surveillance was offered to select patients with renal masses with no evidence of metastasis. Based on imaging studies from the initial diagnosis to the last follow up, tumor growth rates were determined.
Results: Forty-six… More >

Abstract Introduction: Radical cystectomy (RC) remains the gold standard treatment for patients with muscle-invasive bladder cancer. Unfortunately, a significant proportion of patients will have lymph node involvement at the time of RC. We set out to determine the impact of adjuvant cisplatin-based chemotherapy (AC) in a cohort of lymph node positive patients following RC.
Patients and methods: We reviewed our RC database and isolated patients with lymph node positive disease at the time of RC. Univariate and multivariable analysis was performed to identify predictors of poor outcome in patients receiving AC. Overall survival (OS), disease specific survival (DSS)… More >

Abstract A 20-day-old male neonate presented with fever and hydronephrosis. Evaluation revealed that the patient had a single left kidney and a rare combination of multiple congenital malformations: upper pole segmental multicystic dysplasia, ureteropelvic junction obstruction, and an obstructive and refl uxing megaureter (ureterovesical junction obstruction). We performed percutaneous drainage of the infected and obstructed upper collecting system and then used a sequential approach to manage the patient’s anomalies. First, we performed an upper pole partial nephrectomy and pyeloplasty with a modifi ed Y ureterostomy. Second, when the child was older, we performed ureterovesical reimplantation with More >

Abstract Case report: A renal cell cancer patient with late onset of multiorgan metastases showed an unusually long survival following surgical resection. Femoral metastasis appeared 11 years, and contralateral kidney and adrenal gland metastasis 19 years after the primary nephrectomy, respectively. Following the resection of the femur and implantation of endoprosthesis and removal of adrenal gland and partial nephrectomy, the patient was disease-free 20 years after the first diagnosis of cancer.
Conclusion: The long survival and successful treatment underline the importance and efficiency of radical metastasectomy even in the case of late onset multiorgan metastases of renal cell More >

Abstract Ureteral avulsion due to lumbar disc surgery is a rare complication and to our knowledge, only a few cases have been reported in the literature. A43-year-old woman was admitted to our clinic with right lumbar pain following spinal surgery for discopathy. Complete right ureteral avulsion was detected and successfully treated by end-to-end anastomosis of the ureter with an internal double J stent. More >

Abstract Epithelioid hemangioendothelioma (EHE) is a rare vascular tumor of low malignant potential most commonly found in the lung, liver, and soft tissues. Here we describe the very rare presentations of primary EHE in the kidney and on the penis. One patient is a 59-year-old man with a renal lesion found incidentally on surveillance radiography, and the other is a 26-year-old man with an asymptomatic subdermal glanular lesion. Both were treated surgically via open partial nephrectomy and partial penectomy, respectively. Surgery is standard treatment, and close clinical follow up is necessary due to the unpredictable nature More >

Abstract Introduction: The aim of the present study is to determine the preoperative and operative factors associated with bleeding in percutaneous nephrolithotomy (PNL) operations where tract dilatation was formed by balloon dilators.
Material and methods: A total of 378 patients underwent PNL in our department between 2003 and 2008. After excluding missing data 310 patients were included in the study in whom nephrostomy tract dilatation was performed using balloon dilators. The amount of blood loss was estimated by calculating the change in hemoglobin (Hgb). Preoperative and operative factors were assessed for association with the change in Hgb levels.
