    Mehrdad Alemozaffar1, Kenneth Ogan1, Christopher P. Filson1, Dattatraya Patil1, Grace Lee2, Daniel J. Canter3, Gordon Hong4, Viraj A. Master1
    Canadian Journal of Urology, Vol.26, No.5, pp. 9908-9915, 2019
    Abstract Introduction: The use of an electrocautery device (monopolar loop) for patients undergoing transurethral resection of bladder tumors (TURBT) is standard of care. The aim of this study is to establish non-inferiority of complication rates for a bipolar energy device, the PK PlasmaButton (PK Button), when compared to the monopolar loop.
    Materials and methods: Seventy-eight subjects (41 monopolar loop and 37 PK Button), were enrolled in a single-center, prospective, randomized study with cystoscopically detected bladder tumors that were judged endoscopically resectable with only one trip into the operating room. Intra and postoperative data on complication rates, operative time,… More >

    Non-contrast imaging characteristics of papillary renal cell carcinoma: implications for diagnosis and subtyping

    Anand V. Badri1, Nikhil Waingankar2, Kristin Edwards3, Alexander Kutikov1, Rosaleen B. Parsons3, David Y. Chen1, Marc C. Smaldone1, Rosalia Viterbo1, Richard E. Greenberg1, Robert G. Uzzo1
    Canadian Journal of Urology, Vol.26, No.5, pp. 9916-9921, 2019
    Abstract Introduction: Current radiographic guidelines suggest unenhanced renal lesions < 20 Hounsfield Units (HU) are overwhelmingly benign, requiring no further evaluation. We evaluate our experience with papillary renal cell carcinoma (pRCC) presenting with low pre-contrast attenuation and the relationship of attenuation with histologic pRCC subtype.
    Materials and methods: We reviewed our institutional kidney cancer database for patients with pT1 or pT2 pRCC between 2003-2017. Tumors were categorized by papillary subtype by expert uropathologists. Preoperative CT images were analyzed at six regional tumor locations. Low, presumably benign, unenhanced median attenuation was defined as ≤ 20 HU. We calculated the… More >

    Single-dose perioperative mitomycin-C versus thiotepa for low-grade noninvasive bladder cancer

    Kassem Faraj1, Yu-Hui H. Chang2, Kyle M. Rose1, Elizabeth B. Habermann3, David A. Etzioni4, Gail Blodgett1, Erik P. Castle1, Mitchell R. Humphreys1, Mark D. Tyson II1
    Canadian Journal of Urology, Vol.26, No.5, pp. 9922-9930, 2019
    Abstract Introduction: Mitomycin-C (MMC) and thiotepa are intravesical agents effective in reducing the recurrence of low-grade noninvasive bladder cancer when instilled perioperatively. No studies have compared these agents as a single-dose perioperative instillation. This study tests whether there is a difference in recurrence-free survival in patients with low-grade noninvasive bladder cancer who received intravesical MMC versus thiotepa.
    Materials and methods: A retrospective review was performed of patients who underwent cystoscopic excision of a bladder mass identified as a small, low-grade, treatment-naïve, noninvasive, wild-type urothelial carcinoma of the bladder and who received either intravesical thiotepa (30 mg/15 cc) or… More >

    Isolated adrenal metastectomy has a low morbidity rate irrespective of performing surgical sub-specialty

    Kristen E. Gurtner1, Danica N. May1, Jay D. Raman2, Kathleen Lata-Arias1, Daniel J. Canter1
    Canadian Journal of Urology, Vol.26, No.5, pp. 9931-9937, 2019
    Abstract Introduction: There has been growing use of adrenalectomy as a potentially curative treatment option for patients with oligometastatic disease to the adrenal gland. We sought to compare the perioperative outcomes of patients undergoing isolated adrenalectomy in the setting of disseminated cancer using the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database. Furthermore, we examined the impact of performing surgical sub-specialty on outcomes.
    Materials and methods: Data from the ACS-NSQIP database was obtained for patients between 2011 and 2016 who underwent adrenalectomy. Patients were stratified by the presence or absence of disseminated cancer. Univariate and… More >

    Chemotherapy increases survival and downstaging of upper tract urothelial cancer

    Facundo Davaro1, Allison May1, Coleman McFerrin2, Syed J. Raza1, Sameer Siddiqui1, Zachary Hamilton1
    Canadian Journal of Urology, Vol.26, No.5, pp. 9938-9944, 2019
    Abstract Introduction: To evaluate the overall survival and pathologic downstaging effect of neoadjuvant chemotherapy for upper tract urothelial cell carcinoma.
    Materials and methods: The National Cancer Database (NCDB) was queried for patients with stage II-IV upper tract urothelial cell carcinoma undergoing definitive surgical resection (nephroureterectomy) from 2004-2015. Patients with metastatic disease were excluded. Cohorts were stratified by receipt of neoadjuvant chemotherapy (NAC). Kaplan-Meier analysis and Cox regression were used to evaluate overall survival. Logistic regression was used to predict the odds of pathologic downstaging to non-invasive disease (< pT2). Propensity score matched analysis was performed between groups.
    Results: A… More >

    Racial disparities in late-stage prostate cancer: a SEER analysis 2005-2015

    Stephanie Rodriguez, Andrew D. Sparks, Hanbing Zhou, Richard L. Amdur, Jianqing Lin
    Canadian Journal of Urology, Vol.26, No.5, pp. 9946-9951, 2019
    Abstract Introduction: To evaluate the impact of prostate cancer screening guidelines on different racial and ethnic populations.
    Materials and methods: Data was collected from the 2005-2015 Surveillance, Epidemiology, and End Results (SEER) program. Incidence of prostate cancer diagnosis was categorized and analyzed by stage, race/ethnicity, and age group. Appropriate univariate and multivariable statistical analyses were performed.
    Results: The odds of being diagnosed with regional-stage prostate cancer in 2013-2015 were 1.3 times higher for black men, 1.3 times higher for Asian American/Pacific Islander (AAPI) men, and 1.2 times higher for white men when compared to 2005-2008. The odds of being… More >

    Pheochromocytoma arising in the setting of adrenal–renal fusion

    Spyridon P. Basourakos1, Lucas Dean2, James Van Gurp3, Victor Reuter3, Paul Russo2
    Canadian Journal of Urology, Vol.26, No.5, pp. 9952-9955, 2019
    Abstract Adrenal–renal fusion is an anomaly misclassified as a renal tumor due to the absence of pathognomonic radiographic features. Herein, we report a case of a 61-year-old male who underwent a right radical nephrectomy for a presumed renal malignancy. Pathologic evaluation demonstrated a pheochromocytoma in the context of adrenal–renal fusion. Neoplastic transformation of fused adrenal tissue is rare but not unheard of and is typically adrenal cortical in origin. To our knowledge, this is the first description of a pheochromocytoma originating from an adrenal–renal fusion. The clinical presentation did not raise a high index of suspicion More >

    Ectopic ACTH-secreting neuroendocrine tumor: a rare etiology of a pediatric solid renal mass

    Neil J. Kocher1, Justin Loloi2, Joshua Warrick3, Amy S. Burns1, Ross M. Decter1
    Canadian Journal of Urology, Vol.26, No.5, pp. 9956-9959, 2019
    Abstract Neuroendocrine tumors (NETs) are rare tumors with varying clinical presentations. We describe the case of an 11-year-old female presenting with Cushingoid features in the setting of a left-sided flank mass. Her presentation and evaluation suggested a paraneoplastic ectopic ACTH syndrome. She underwent open left radical nephrectomy and final pathology confirming a high-grade NET with nodal metastasis. Although exceedingly rare, ACTH-secreting tumors of the kidney can cause significant morbidity and mortality and so we recommend it be included in the differential diagnosis of pediatric renal masses.

    Anatomic GreenLight laser vaporization-incision technique for benign prostatic hyperplasia using the XPS LBO-180W system: How I do it

    Kyle W. Law1, Dean S. Elterman2, Hannes Cash3, Enrique Rijo4, Bilal Chughtai5, Vincent Misrai6, Kevin C. Zorn1
    Canadian Journal of Urology, Vol.26, No.5, pp. 9963-9972, 2019
    Abstract For men experiencing lower urinary tract symptoms (LUTS) refractory to medical therapy, there have been numerous developments in the treatment options offered for benign prostatic hyperplasia (BPH) in the recent years. Transurethral resection of the prostate (TURP) has remained the reference standard for men with prostates sized 30 cc-80 cc, while open prostatectomy is universally guidelines-recommended in the absence of enucleation, for men with prostates larger than 80 cc-100 cc. While these techniques are effective, they have the potential for bleeding complications requiring transfusions, electrolyte abnormalities such as TURP syndrome, and often require prolonged hospitalization.… More >
