Abstract A 61-year-old male presented with long standing urinary frequency and the sensation of incomplete emptying. Computed tomography (CT) revealed a 9.5 cm x 7.9 cm x 6.9 cm pelvic mass behind the bladder and abutting the rectum. The mass was excised using a robotic-assisted laparoscopic approach. Pathologic examination of the mass demonstrated an extragastrointestinal stromal tumor (EGIST), an extremely rare entity. To the best of our knowledge, this is the fi rst EGIST to be found in the rectovesicular pouch of a male and the fi rst to be resected robotically. Our case adds to More >

Abstract The management of post-prostatectomy erectile function has been debated since the nerve sparing radical prostatectomy was fi rst introduced. A number of penile rehabilitation protocols have been proposed with varying degrees of success and patient satisfaction. My management of post-prostatectomy erectile dysfunction has evolved based on an honest and critical appraisal of the literature and my own experience and research. A review of major studies published on the topic of post-prostatectomy penile rehabilitation is included here, in addition to a critical evaluation of my own clinical practice. After evaluating the effi cacy of these various More >

Abstract Introduction: Erectile dysfunction (ED) is a common complication following bilateral nerve-sparing robotic prostatectomy (BNSRP). Early intervention with tadalafil plus a vacuum erection device (VED) may enhance the recovery of sexual function compared to tadalafil alone.
Materials and methods: Men who underwent BNSRP for prostate cancer were randomized into two groups: one received tadalafil 20 mg three times weekly, and the other received the same dose of tadalafil plus daily use of a VED for at least 10 minutes unbanded per day, five days per week. Treatment began one month post-surgery. Clinic visits occurred at 1, 3, 6,… More >

Abstract Objectives: Urolithiasis is an increasing problem among patients aged 80 years and older. Our objective was to compare patients aged ≥ 80 years with a younger cohort in terms of presentation and management of urolithiasis.
Methods: Patients referred to a tertiary care stone clinic for the management of urolithiasis over a 5-year period were reviewed. Clinical data from patients aged ≥ 80 years were compared with a random sample of those under 80 years.
Results: There were 26 patients aged ≥ 80 years and 102 patients in the younger cohort; mean ages were 83.5 ± 0.6 and 50.1… More >

Abstract Introduction: Prostate cancer is the second leading cause of cancer death among men in developed countries. Estrogen receptor-alpha (ER-α), vitamin D receptor (VDR), and the calcium-sensing receptor (CaSR), partly through their effects on calcium levels are implicated in the proliferation and carcinogenesis in the prostate gland. VDR, ER-α and CaSR genes show polymorphisms in humans that appear to have clinical significance in many pathological conditions, such as prostate cancer. Our aim was to evaluate the role of ER-α (PvuII, XbaI), VDR (BsmI) and CaSR (A986S) gene polymorphisms and serum calcium levels in the pathogenesis of prostate… More >

Abstract Introduction: Spinal anesthesia for ambulatory transurethral resection of the prostate (TURP) is a well-established technique. This study reviews data collected over a 5-year period at a major Canadian tertiary academic center. The purpose of the study was to evaluate our experience and complications associated with spinal anesthesia using a combination of low-dose local anesthetic and narcotic in ambulatory TURP procedures.
Methods: Medical records were retrospectively reviewed for all ambulatory TURP patients treated between January 2000 and September 2005 at our Surgical Day Care Center. All spinal anesthetics were reviewed and classified based on dosage into: low-dose bupivacaine… More >

Abstract Introduction: Several animal models have been used for in vitro experimentation and surgical training exercises involving the vas deferens. The canine model is currently considered the standard for both in vivo and ex vivo studies. However, due to increasing costs associated with canine experimentation and in accordance with the principles of refine, reduce, and replace, a novel model that is cost-effective and easily obtainable is desired. We compared the morphology of the bull vas deferens with that of the human and canine vas deferens.
Materials and methods: Bilateral vas deferens tissue from human (n = 6), canine… More >

Abstract Introduction: Urodynamic assessment is strongly recommended before artificial urinary sphincter (AUS) implantation. Detrusor overactivity (DO) and/or hypersensitivity and/or mild loss of compliance are frequently demonstrated in post prostatectomy incontinence. The aim of this study was to evaluate urodynamic parameter changes before and after AUS implantation in patients with urinary incontinence post-radical prostatectomy (RP) and concomitant urodynamic bladder abnormalities.
Materials and methods: We performed a retrospective review of charts pre- and post-AUS implantation. Sixteen out of a cohort of 52 patients met our inclusion criteria: stress urinary incontinence (SUI) due to RP and bladder dysfunction (early bladder sensation… More >

Abstract Introduction: To assess the accuracy of sonouroflow (SUF), an at-home, wireless-based acoustic system for recording lower urinary tract symptoms (LUTS) and urinary flow rate, and to compare test-to-test variability in flow parameters recorded using this new portable method with those obtained by conventional uroflowmetry.
Materials and methods: An initial pilot study evaluated the technical feasibility of the SUF system. Subsequently, test-to-test variability was compared between sonourograms (SUFm) and standard uroflowmetry recordings. Uroflowmetry tests were performed at the urology office at pre-set times. SUF tests were performed at home on a schedule in keeping with the subjects' normal habits.
