INTRODUCTION: Children with neurogenic bladder (NGB) often require a lifetime of clean intermittent catheterization (CIC), typically using uncoated catheters (UCs). Hydrophilic catheters (HCs) have lower friction than UCs with reported less damage to the urethra. The purpose of this study is to compare outcomes between these catheters. METHODS: An investigator-initiated, prospective, randomized clinical trial was conducted to compare HCs versus UCs. Children aged 2-17 years with NGB on CIC were enrolled for 1 year...

OBJECTIVES: To explore if the mechanism of the voiding dysfunction caused by spinal cord injury in rats can be improved by intravenous administration of the 5-HT2A/2C receptor agonist, DOI, and discuss whether it can be ascribed to serotonin 2A and 2C receptor up-regulation in lumbosacral cord motoneurons. MATERIALS AND METHODS: Female Sprague-Dawley rats were used, which were divided into two groups (Spinal cord injury group VS Normal control group). Under urethane anesthesia, cystometry was performed to examine the variation of urodynamic parameters before and after successive intrathecal administration of various doses of DOI into the lumbosacral cord...

Pelvic fracture urethral injuries (PFUI) are devastating lesions leading to fibrosis and urethral disruption resulting in recurrent strictures, urinary incontinence, fistulae and even erectile dysfunction, representing a management problem for the urologist. Magnetic resonance imaging (MRI) may be a valuable tool in establishing or confirming the diagnosis by providing detailed anatomy and estimating disease extent. We present a comprehensive review of the current literature on the role of MRI on diagnostic evaluation and surgical management of these patients...

BACKGROUND: Post-traumatic posterior urethral injuries in children are rare events. Their management algorithms are extrapolations from adult literature and they continue to pose a difficult challenge for pediatric urologists. Not much data for age-related feasibility of an end-to-end urethroplasty are available. OBJECTIVE: This study was designed to validate a simple preoperative radiographic score to predict the type of surgical repair for traumatic posterior urethral strictures in children...

Trauma and injury continue to be common in children and remain an important cause of mortality and morbidity. Legislation mandating the use of helmets for all cyclists appears to have been effective in reducing the incidence and severity of head and facial injuries, with no clear evidence of a reduction in cycling usage or activity. Straddle injuries, whilst uncommon and generally minor, require careful clinical assessment as they may be associated with urethral trauma. Quad bikes remain highly dangerous with continuing reports of deaths in child riders due to their inherent lack of stability: a ban on their use by children would seem the most effective solution...

The objective of the study was to evaluate the relationship between the sexual position and severity of penile fracture (PF). We studied 90 patients with PF. The mechanism of injury and the sexual position was assessed. We divided our sample by the etiology of the fracture in six groups: (a) masturbation or penile manipulation; (b) 'man-on-top' position; (c) 'doggy style' position; (d) 'woman-on-top' position; (d) blunt trauma; and (e) 'rolling over' fracture. We used the χ(2)-test for contingency analysis of the populations under study (P<0...

OBJECTIVE: To examine possible etiology and treatment outcomes in 21 patients with glans necrosis following penile prosthesis implantation. METHODS: Glans necrosis typically presented with a dusky glans on first post-operative day following prosthesis implantation. RESULTS: The blood supply to the glans penis consists of the dorsal arteries and the terminal branches of the spongiosal arteries. Using this cohort, we compiled pre-operative comorbidities and adjunctive surgical maneuvers that might compromise glans vascularity leading to glans necrosis...

Lower urinary tract symptoms secondary to posterior urethral valves (PUV) arise in boys during adolescence. The reasons for this have previously been attributed to increased urine output as boys experience increased growth. Additionally, there are few choices for clinicians to effectively treat these complications. We formed the new hypothesis that increased androgen levels at this time of childhood development could play a role at the cellular level in obstructed bladders. To test this hypothesis, we investigated the role of testosterone on bladder detrusor muscle following injury from partial bladder outlet obstruction (PO) in mice...

We examined bladder and urethral sphincter activity in mice with or without spinal cord injury (SCI) after C-fiber afferent desensitization induced by capsaicin pretreatment and changes in electrophysiological properties of mouse bladder afferent neurons 4 weeks after SCI. Female C57BL/6N mice were divided into 4 groups; (1) spinal intact (SI)-control, (2) SI-capsaicin pretreatment (Cap), (3) SCI-control and (4) SCI-Cap groups. Continuous cystometry and external urethral sphincter (EUS)-electromyogram (EMG) were conducted under an awake condition...

The risk of urethral injury during transanal total mesorectal excision (taTME) is delineated, and potential risk factors for iatrogenic transection are reviewed. A variety of applied and theoretical techniques can be used by surgeons to diminish the risk of injury in males undergoing this operation. Many of the approaches utilize non-optic media and wavelengths beyond the visible light spectrum which can enhance the surgeon's frame of reference. The aim of the present study was to assess the techniques and theoretical approaches to urethral localization during taTME...

The classic presentation of penile fracture is a cracking or snap sound, with sharp pain, immediate detumescence, swelling, deformation and ecchymosis. A penile fracture involves rupture of the tunica albuginea of one or both corpora cavernosa. Concomitant urethral rupture is reported to occur in 10% to 20% of penile fracture cases. Isolated urethral injury without penile fracture is extremely rare. We report the first case of isolated pendulous urethral rupture from an abrupt coital distractive force. We include a literature review and discussion of isolated urethral trauma secondary to sexual intercourse...

BACKGROUND: Patients with spinal cord injury (SCI) that carry indwelling urinary catheters have an increased risk of urinary tract infection (UTIs). Antiseptic Silver Alloy-Coated silicone (SAC) urinary catheters prove to be a promising intervention to reduce UTIs; however, current evidence cannot be extrapolated to spinal cord injured patients. PURPOSE: Assess the efficacy of SAC urinary catheters for preventing catheter-associated urinary tract infections (CA-UTI)...

Our patient suffered a perineal straddle injury, resulting in right cavernosal artery pseudoaneurysm in combination with a cavernosal-urethral fistula. The urethra failed to heal after several weeks and the patient presented with severe intermittent urethral bleeding. The pseudoaneurysm was successfully treated by coil embolization, with resolution of the bleeding. The patient recovered completely, with normal erectile and voiding function. This type of injury is very rare in literature: traumatic cavernosal arterial pseudoaneurysm is known to cause high flow priapism, but in this case additional cavernosal-urethral fistula resulted in a severe urethraggia...

BACKGROUND: Urethral injury is a complication feared by surgeons performing transanal TME (TaTME) or abdominoperineal excision (APE) procedures. Injury during TaTME occurs when the prostate is inadvertently mobilised or as a direct injury similar to the direct injury during the perineal dissection of APE procedures. We performed a proof of principle study to assess the feasibility of using indocyanine green (ICG) to fluoresce the urethra in human cadavers. METHODS: Indocyanine green at varying doses was mixed with Instillagel and infiltrated into the urethra of male human cadavers...

Penile fracture (PF) is considered an emergency in urology. In the literature there are some case series reporting considerable incidence of PF in some parts of Iran. There are no accurate data about the incidence of PF all around Iran. Although it may be uncommon in other parts of the country and in the other countries, it can also be underreported. There are some challenges in diagnosis, management, and also reporting of these cases. In this review of Iranian medical literature, we searched for penile fracture and penile injury keywords in Medline, Scopus, SID, Google and Persian medical journals...

AIMS: This two phase study aimed to explore health care professionals' teaching and prescribing practice related to intermittent catheterisation and to identify their perceptions about the possible implementation of a mixed (single and multi-use) package for intermittent catheterization. INTRODUCTION: Single-use intermittent catheters are the norm in the UK although multi-use is common in some other countries. A recent Cochrane review found no difference in complications, including urinary tract infection rates, between those using single or multi-use catheters...
