Especially, insufficient strength of the pelvic floor muscles including the urethral sphincter muscles causes urinary incontinence (UI). Thus, it is most important to understand the main mechanism causing UI and the relationship of UI with the urethral sphincter. Functionally and anatomically, the urethral sphincter is made up of the internal and the external sphincter. We highlight the basic and clinical anatomy of the internal and the external sphinc- ter and their clinical meaning. Understanding these relationships may provide a novel view in identifying the main mechanism causing UI and surgical techniques for UI.

UIJ Urotoday International Journal® the Short-Term Outcome of Urethral Stricture Disease Management in HIV and Non-HIV Infected Patients: a Comparative Study
UIJ UroToday International Journal® The Short-Term Outcome of Urethral Stricture Disease Management in HIV and Non-HIV Infected Patients: A Comparative Study Mohamed Awny Labib, Michael Silumbe, Kasonde Bowa Submitted April 30, 2012 - Accepted for Publication December 27, 2012 ABSTRACT Purpose: This study intends to compare short-term outcomes of treatment of urethral stricture disease between human immunodeficiency virus (HIV) seropositive and HIV seronegative patients at the University Teaching Hospital (UTH) in Lusaka. Methods: This was a prospective cohort study conducted on patients presenting with urethral stricture disease at the UTH, Lusaka, Zambia, between October 2009 and December 2010. One arm included HIV seropositive patients and the other arm had HIV seronegative patients. The recruited patients underwent urethral dilatation, anastomotic urethroplasty, and staged urethroplasty. They were followed-up postoperatively for 6 months, and recurrence and complication rates were compared between the 2 groups. Other parameters studied included patient demographics, cluster of differentiation (CD4) cell counts in positive patients, HIV World Health Organization (WHO) stages, stricture etiology, stricture sites, and stricture lengths. The collected data was analyzed using SPSS 16. Results: A total of 71 patients with a mean age of 38.04 years who had urethral stricture disease were recruited for this study. Of the patients, 37% (26) were HIV seropositive while 63% (45) were seronegative, and 53.8% (14) of the seropositive patients were on highly active antiretroviral therapy (HAART). Of the urethral strictures, 45% (32) resulted from urethritis, and the prevalence of HIV in patients presenting with post-urethritis stricture disease was 50% (16/32). Of the strictures, 73.2% (N = 52) were located in the bulbar urethra, 19.7% (N = 14) were in the penile urethra, and 5.6% (N = 4) were located in the membranous urethra. -

A Case of Seminal Vesicle / Prostatic Reflux Causing Intense Focal

A 66-year-old man with a history of prostatism and benign prostate hypertrophy presented with elevated prostate-specific antigen. Three prostatic biopsies obtained by transrectal ultrasonography (TRUS) were negative for malignancy. Magnetic resonance imaging of the prostate revealed a hypointense signal at the right prostate base on T2-weighted images. FDG positron emission tomography/computed tomography (CT) was performed for further evaluation and demonstrated intense FDG activity, similar to urine, posterior to the prostate. Delayed CT scan showed serpiginous excretion of contrast into the seminal vesicles and peripheral zone of the prostate, corresponding to areas of intense and persistent FDG activity, compatible with seminal vesicle and prostatic reflux of urine resulting in intense FDG uptake. Awareness of this pathological entity that may be a complication of TRUS or due to chronic prostatitis may avoid misinterpretation, especially in the absence of administration of CT contrast to delineate -
Benign Prostatic Hyperplasia DEFINITION OF
Introduction Introduction enign prostatic hyperplasia (BPH) is an increasingly B common condition in aged males. By the age of 60 years, more than 50% of men will have microscopic evidence of the disease, and more than 40% of men beyond this age will have lower urinary tract symptoms (LUTS) (Chute and Panser, 1993). LUTS are the most common problem that affects BPH patients, and include urinary frequency, urgency, weak stream, straining and nocturia (Trueman et al, 1999) (Wu et al, 2006). Although urologists normally attribute LUTS that are concomitant with BPH to urinary obstruction caused by enlarged prostate, some controversies still exist (Bosch et al, 2008). Several studies have shown that there are correlations between urinary symptoms and prostate volume, peak flow rate or residual urine volume (Madersbacher et al, 1997). However, others have found that prostate volume is not associated with LUTS, and objective parameters cannot predict the severity of symptoms in BPH patients (KEzzeldin et al, 1996) (Tubaroa and Vecchia, 2004). 1 Introduction Because most of these studies have been carried in Western countries, evidence in Oriental populations is still lacking. Almost 20 years ago, Barry and his collagues suggested that by using a simple questionnaire, which was later validated, physicians could quantify urine storage and voiding symptoms reported by patients with BPH or LUTS (Barry et al, 1995). The questionnaire also included a question about quality of life, which can also be called the “bothersome index” or “motivational index” question. That question asked, “If you were to spend the rest of your life with your urinary condition the way it is now, how would you feel about that?” From this was born the International Prostate Symptom Score (I-PSS), which became the gold standard outcome measurement for most clinical trials that assessed responses to interventions for the management of BPH (Becher et al, 2009). -

THE ROLE OF THE EXTERNAL SPHINCTER By J. COSBIE Ross Director of Urological Studies, University of Liverpool Introduction. It must be acknowledged that as yet no one knows the precise role of the external sphincter and there should, by right, be a question mark after the word 'sphincter'. The problem is much more complex and obscure than the simple, easily understood mechanism of the anal sphincter. However, there is much that is already known, and perhaps recent work has shed some light on the problem. First, the traditional view. In the 32nd Edition of Gray's Anatomy (1958), the description is as follows. 'The sphincter urethrae surrounds the membranous portion of the urethra, and lies deep to the inferior fascia of the urogenital diaphragm. Its superficial or inferior fibres arise in front from the transverse perineal ligament and from the neighbouring fascia. They pass backwards on each side of the urethra and converge on the perineal body for their insertion. Its deep fibres, some of which arise from the fascial sheath of the pudendal vessels and pass medially, form a continuous circular investment for the membranous urethra.' Actions. 'The muscles of both sides act together as a sphincter, compressing the membranous part of the urethra.
