    Robotic versus laparoscopic radical nephrectomy: comparative analysis and cost considerations

    Mark R. Helmers, Mark W. Ball, Michael A. Gorin, Phillip M. Pierorazio, Mohamad E. Allaf
    Canadian Journal of Urology, Vol.23, No.5, pp. 8435-8440, 2016
    Abstract Introduction: Robotic-assisted laparoscopic radical nephrectomy (RRN) is an increasingly utilized alternative to laparoscopic radical nephrectomy (LRN); however, there is little data on comparative effectiveness and cost of these procedures. We analyzed perioperative outcomes and hospital charge differences among patients undergoing laparoscopic radical nephrectomy (LRN) and robotic radical nephrectomy (RRN).
    Materials and methods: Our institutional renal mass registry was queried for patients who underwent either LRN or RRN from 2010 to 2014. Demographic, perioperative outcomes and hospital charge data were compared between surgical approaches.
    Results: Overall, 319 minimally invasive radical nephrectomies were performed during the study period. Of these,… More >

    David E. Rapp1,3, Nada L. Wood1, Matthew Bassignani1, Luke Gergoudis2, Sarah Caulkins3, Eugene V. Kramolowsky1,3
    Canadian Journal of Urology, Vol.23, No.5, pp. 8441-8445, 2016
    Abstract Introduction: Non-contrast CT (NCT) is commonly used to evaluate flank pain (FP). We sought to evaluate incidence of ureteral calculi on NCT in patients with FP, and to determine if clinical variables are associated with higher detection rates.
    Materials and methods: Retrospective review identified 613 patients undergoing NCT for FP. Patient clinical data, NCT findings, and intervention were analyzed. Focus was placed on variables commonly associated with urolithiasis (Vstone), comprising hematuria, nausea/vomiting, and prior stone history. Statistical analysis was performed to identify risk of ureteral stones based on number and type of Vstone.
    Results: No stone disease was identified… More >

    Urinalysis fndings are not predictive of positive urine culture in patients with indwelling stents

    Aydin Pooli, Gates Cook, Sudhir Isharwal, Vikas Desai, Chad LaGrange
    Canadian Journal of Urology, Vol.23, No.5, pp. 8446-8450, 2016
    Abstract Introduction: Indwelling stents produce symptoms and urinalysis findings mimicking urinary tract infection (UTI). In this study, we investigated the correlation of urinalysis findings with urine culture in patients with indwelling ureteral stents.
    Materials and methods: All patients with ureteral stents who underwent stent removal in urology clinic from July 2013 to January 2015 and had urine culture available immediately prior to stent removal were included in this study. Urine culture results as well as age, gender, duration of indwelling stent, and reason for stent placement were collected.
    Results: A total of 122 patients were included in this study.… More >

    Abdullah M. Alenizi1,3, Kevin C. Zorn2, Marc Bienz2, Emad Rajih2, Pierre Alain Hueber2, Naif Al-Hathal1, Serge Benayoun1, Thierry Lebeau1, Assaad El-Hakim1
    Canadian Journal of Urology, Vol.23, No.5, pp. 8451-8456, 2016
    Abstract Introduction: To evaluate erectile function recovery following robotic-assisted radical prostatectomy (RARP) according to preoperative sexual health inventory for men (SHIM) score stratification.
    Materials and methods: We prospectively collected data on 250 consecutive patients who underwent RARP by a single surgeon between October 2006 and October 2012. Thirty-six patients were excluded because of lack of preoperative SHIM score. All patients had a minimum follow up of 2 years. Patients were divided into four groups according to their preoperative SHIM score: group 1 with normal potency (SHIM 22-25), group 2 with mild ED (SHIM 17-21), group 3 with mild-moderate… More >

    Poor split renal function and age in adult patients with ureteropelvic junction obstruction do not impact functional outcomes of pyeloplasty

    Nirmish Singla, Aaron H. Lay, Jeffrey A. Cadeddu
    Canadian Journal of Urology, Vol.23, No.5, pp. 8457-8464, 2016
    Abstract Introduction: To examine if poor preoperative split renal function (SRF) and age influence pyeloplasty outcomes in adults with ureteropelvic junction obstruction (UPJO).
    Materials and methods: We retrospectively reviewed our pyeloplasty experience in adults with UPJO from 2004 to 2014. Patients with solitary kidneys or missing renal scans were excluded. Renal scans were performed at 6 weeks, 8 months, and 20-24 months postoperatively. Demographics, operative approaches, and pre and postoperative SRF and diuretic half-times (T1/2) were obtained. Patients were stratified by preoperative SRF (≤ or > 25%) and age. Cox regression analyses were performed to explore predictors for stability… More >

    Infectious complications associated with the use of temporary prostatic urethral stents in patients with benign prostatic hyperplasia

    Haidar M. Abdul-Muhsin1, Nicholas J. Jakob1, Ryan M. McLemore2, Sean B. McAdams1, Mitchell R. Humphreys1
    Canadian Journal of Urology, Vol.23, No.5, pp. 8465-8470, 2016
    Abstract Introduction: To examine the infectious outcomes after the insertion of the temporary prostatic urethral stent (TPUS) in benign prostatic hyperplasia (BPH) patients.
    Material and methods: Between November 2007 and September 2012, ninety TPUS were used in 33 patients with BPH at our institution. All patients had negative urine cultures prior to the first stent insertion. TPUS were sent for cultures at time of removal or exchange. Stents were removed at the time of definite surgical intervention, at 4-6 weeks, or when patients elected another course of treatment. Colonization was defined as asymptomatic positive stent culture. Infection was… More >

    Astandardized surgical technique for removal of the Interstim tined lead

    Matthew E. Sterling, Siobhan M. Hartigan, Alan J. Wein, Ariana L. Smith
    Canadian Journal of Urology, Vol.23, No.5, pp. 8471-8475, 2016
    Abstract Introduction: Explantation of the Interstim sacral neuromodulation (SNM) device is occasionally necessary. Removing the tined lead can put strain on the lead, resulting in a possible break and retained fragments. The Food and Drug Administration (FDA) released a notification regarding health consequences related to retained lead fragments. We describe a novel and safe surgical technique for removing the Interstim device and permanent lead.
    Materials and methods: We searched the Manufacturer and User Facility Device Experience (MAUDE) database for complications related to tined lead removal and searched the database of a single surgeon at our institution. Our standardized… More >

    Wire in the hole: a case series of eroded intrapubic wire sutures causing genitourinary complications in the bladder exstrophy complex

    Joan S. Ko, Angela D. Gupta, Heather N. Di Carlo, Kathy Lue, John P. Gearhart
    Canadian Journal of Urology, Vol.23, No.5, pp. 8476-8479, 2016
    Abstract Bladder exstrophy and cloacal exstrophy are rare congenital defects of the genitourinary tract that require complex surgical reconstruction. Malrotation of the bony pelvis causes a characteristic diastasis of the pubic symphysis, which is surgically reduced at the time of initial bladder closure. For a successful primary closure without tension such that the bladder can be placed deep within the pelvis, pelvic osteotomy is often used. However, alternative techniques have been utilized to bring the pubic rami into apposition. The authors present four bladder/ cloacal exstrophy patients in which an intrapubic wire was used for pubic More >

    Pyelocystostomy for treatment of recurrent nephrolithiasis and ureteropelvic junction obstruction in a pelvic kidney

    Hazem Elmansy*, Jafar Hussaen*, Mostafa Elhilali, Sero Andonian
    Canadian Journal of Urology, Vol.23, No.5, pp. 8480-8482, 2016
    Abstract Patients with pelvic kidneys are at an increased risk of developing ureteropelvic junction obstruction (UPJO) and nephrolithiasis with limited endourologic options. A 54-year-old man with a left pelvic kidney, recurrent nephrolithiasis, and 12 previous ureteroscopies presented with left UPJO and lower pole calyceal stones. After two failed ureteroscopic attempts, an open pyelolithotomy and pyelocystostomy were performed. After 30 months, he continues to be asymptomatic without recurrence of nephrolithiasis. This constitutes the fifth such reported case. Therefore, pyelocystotomy is a good option for patients with pelvic kidneys, UPJO and recurrent nephrolithiasis refractory to endourologic procedures.

    MLL translocation in two castration-resistant prostate cancer patients

    Rajasree Pia Chowdry1, Elisa Ledet2, Lahiru Ranasinghe3, Alton Oliver Sartor2
    Canadian Journal of Urology, Vol.23, No.5, pp. 8483-8486, 2016
    Abstract The mixed-lineage leukemia (MLL) protein acts as a histone methyltransferase regulating multiple genetic elements. Rearrangements of the MLL gene result in expression of MLL-fusion proteins that occur in some acute leukemias and are associated with poor prognosis. The MLL protein complex has been shown to interact with the androgen receptor via the MLL-menin subunit, thus promoting gene activation. The presence of MLL translocation has not been previously reported in patients with castrate resistant prostate cancer (CRPC). We describe two cases of metastatic CRPC with a translocation in the MLL gene detected by a specific fluorescent More >

    Early pregnancy likely caused by an intravesical intrauterine device

    Jim K. Shen, Edmund Y. Ko, Andrea Staack
    Canadian Journal of Urology, Vol.23, No.5, pp. 8487-8490, 2016
    Abstract A 42-year-old female with remote history of intrauterine device (IUD) placement presented with gross hematuria, urinary urgency, and dyspareunia. Cystoscopy showed an encrusted, free-floating intravesical foreign body consistent with a heavily calcified IUD. It was removed endoscopically using holmium laser cystolitholapaxy. The patient remained symptom free postoperatively. While most intravesical IUDs are thought to be the result of migration after several months, this patient became pregnant within 4 weeks after initial insertion. Therefore this may represent a case either of early intravesical migration or of accidental IUD placement into the bladder at the time of More >

    HOW I DO IT

    How I do it: Same day discharge for transurethral resection of prostate using Olympus PlasmaButton and PlasmaLoop

    Ryan Pham1, Jacob Parke2, Kenneth M. Kernen1,3
    Canadian Journal of Urology, Vol.23, No.5, pp. 8491-8494, 2016
    Abstract Benign prostatic hyperplasia (BPH) is one of the most common conditions affecting older men. Transurethral resection of the prostate (TURP) has widely been considered the gold standard in surgical treatment for BPH. However, this procedure remains largely an inpatient procedure. Inpatient admission ultimately adds to healthcare cost and patient morbidity. In this article, we present an alternative methodology to treat BPH using combination Olympus PlasmaButton and Olympus PlasmaLoop therapy. Preliminary results from our experience suggest improved hemostasis with adequate resection, allowing a majority of our patients to be discharged the same day of the procedure. More >

    Canadian Pediatrics Society position statement on newborn circumcision: a risk-benefit analysis revisited

    Brian J. Morris1, Jeffrey D. Klausner2, John N. Krieger3, Bradley J. Willcox4, Pierre D. Crouse5, Neil Pollock6
    Canadian Journal of Urology, Vol.23, No.5, pp. 8495-8502, 2016
    Abstract Introduction: The Canadian Pediatrics Society (CPS) recently released a position statement on early infant (newborn) male circumcision (EIMC). It concluded that since benefits do not exceed risks, circumcision should only be performed on boys in high-risk populations or circumstances. This contradicts recommendations by the American Academy of Pediatrics and the Centers for Disease Control and Prevention (CDC) whose policies each support more widespread implementation of EIMC. Here we review the CPS statement, particularly its risk-benefit analysis, to determine the basis for this disparity.
    Materials and methods: We performed a risk-benefit analysis based on relevant literature retrieved from… More >
