M B Pryanichnikova, O V Zhurkina
The article describes open surgical modalities for managing patients with severe obliterations of the anterior urethra. The mean age of patients was 70 years. The causes of urethral strictures and obliteration included prostatic adenomectomy, scrotal abscess with pelvic bone osteomyelitis, accidental removal of the bulbar and penile urethra during herniotomy and a prolonged use of an indwelling urethral catheter. Two patients underwent perineostomy (median and trapezoidal). In the third patient, scrotal skin was used to form "scrotal hypospadias" (a modified Johansons operation) and the fourth patient underwent Mikhalovskiis operation...

AIM: To improve treatment results in patients after multiple hypospadias repairs by optimizing the postoperative management. MATERIALS AND METHODS: Eighty-two patients (mean age 48.1+/-15.3 years) with urethral strictures secondary to failed hypospadias repairs underwent staged graft urethroplasty using oral mucosa (cheek, lip, tongue) as a grafting material. In 62 patients, at the end of surgery the bladder was drained with a standard Foley catheter. In twenty patients the bladder was drained with a modified silicone urethral catheter, which had an additional channel for delivering drugs and removing the urethral wound effluent, and a second additional channel for inflating a balloon fixed to the catheter tube at different parts of the catheter...

AIMS: To present our technique of suprameatal urethrolysis with Martius flap (SMUM) and outcomes of this procedure for refractory female bladder outflow obstruction (BOO). METHODS: A retrospective chart review was performed to identify female patients who underwent SMUM between January 2010 and August 2016 after failed transvaginal urethrolysis (TVU) for BOO due to prior stress urinary incontinence (SUI) surgery. The primary outcome measure was surgical success defined as patient ability to void volitionally without need for catheterization or additional surgery for BOO...

INTRODUCTION/OBJECTIVE: Proximal hypospadias is one of the most challenging conditions that pediatric urologists have to deal with. Many procedures have been devised over the years, but nothing has been proven to be the best option. Although there have been some attempts at correcting severe hypospadias in one procedure, most have advocated a staged approach. The classic approach - laying penile skin or a graft within a split glans followed by glanuloplasty at the second stage - by definition requires two operations on the glans...

We determined minimum inhibitory concentrations (MICs) of 41 antimicrobial agents for 73 clinical strains of Haemophilusinfluenzae isolated from the urethra of men with acute urethritis and/or epididymitis and examined the strains for the production of β-lactamase. We also compared their antimicrobial susceptibilities with those of H. influenzae strains from respiratory tract or otorhinolaryngological infections that were reported in Japan. The proportion of β-lactamase-nonproducing ampicillin-resistant strains from acute urethritis and/or epididymitis appeared to be lower, but that of β-lactamase-producing ampicillin-resistant strains appeared to be higher, compared with those from respiratory tract or otorhinolaryngological infections...

Urinary tract infections (UTIs) caused by uropathogenic Escherichia coli (UPEC) affect 150 million people annually. Despite effective antibiotic therapy, 30-50% of patients experience recurrent UTIs. In addition, the growing prevalence of UPEC that are resistant to last-line antibiotic treatments, and more recently to carbapenems and colistin, make UTI a prime example of the antibiotic-resistance crisis and emphasize the need for new approaches to treat and prevent bacterial infections. UPEC strains establish reservoirs in the gut from which they are shed in the faeces, and can colonize the periurethral area or vagina and subsequently ascend through the urethra to the urinary tract, where they cause UTIs...

Zachary C Danziger, Warren M Grill
Lower urinary tract reflexes are mediated by peripheral afferents from the bladder (primarily in the pelvic nerve) and the urethra (in the pudendal and pelvic nerves) to maintain continence or initiate micturition. If fluid enters the urethra at low bladder volumes, reflexes relax the bladder and evoke external urethral sphincter (EUS) contraction (guarding reflex) to maintain continence. Conversely, urethral flow at high bladder volumes, excites the bladder (micturition reflex) and relaxes the EUS (augmenting reflex)...

Vesicoureteral reflux (VUR) is one of the most common diseases in pediatric urology and classified into primary and secondary VUR. Although posterior urethral valve (PUV) is well known as a cause of the secondary VUR, it is controversial that minor urethral deformity recognized in voiding cystourethrography represents mild end of PUV spectrum and contributes to the secondary VUR. We have been studying for these ten years congenital urethral obstructive lesions with special attention to its urethrographic and endoscopic morphology as well as therapeutic response with transurethral incision...

A congenital megalourethra is an enlargement of the pendulous urethra without evidence of distal obstruction. A 1-month-old boy presented to us with complaint of weak stream, ballooning of the penis before and during voiding and post voiding dribbling, since birth. Physical examination and cystourethroscope confirmed the diagnosis of congenital scaphoid megalourethra. He underwent reduction urethroplasty. During postoperative follow up, he had normal looking penis with good urinary stream.

We report surgical management of a disrupted radical prostatectomy vesicourethral anastomosis after bleeding from undiagnosed hemophilia that required re-exploration, pudendal artery embolization, and urinary diversion with nephrostomy and surgical drains. After referral, the 4.5 cm vesicourethral anastomotic defect was reconstructed with a robotic-assisted abdomino-perineal approach. Intra-abdominal robotic-assisted mobilization of the bladder and perineal mobilization of the urethra permitted a tension-free vesicourethral anastomosis while avoiding a pubectomy...

Urinary bladder torsion is rare in dogs. It is characterised by rotation of the organ along its longitudinal axis and is potentially life-threatening because of urinary flow obstruction with subsequent urine retention, hydroureter, hydronephrosis and azotaemia. This report describes the computed tomographic features of urinary bladder torsion in two dogs. In both cases, the hallmark indicative of torsion was the "whirl sign," originating from the twisted pelvic urethra and urinary bladder neck encircling the ureters, blood vessels and bladder ligaments in a characteristic spiral pattern...

Congenital anomalies of the kidneys and urinary tract (CAKUT) are found in 3-6 out of 1.000 of the newborns, or according to some statistics they are represented in 0.5% of all pregnancies. Congenital abnormalities of the kidneys and urinary tract present a family of diseases of various anatomic spectrum, including renal anomalies, and anomalies of the bladder and urethra. The study was retrospective-prospective which means that it included newly diagnosed patients suffering from CAKUT, as well as those patients with already diagnosed and well defined CAKUT on the basis of imaging studies which have been processed according to the protocol for this study...

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...

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...

BACKGROUND: Nephrogenic adenoma is an uncommon benign lesion that occurs at several sites in urinary tract, from the renal pelvis to urethra, with the highest frequency in urinary bladder. Nephrogenic adenoma displays a broad spectrum of architectural and cytological features. Hence, recognition of its characteristic histopathological features is needed to distinguish this lesion from its mimickers. MATERIALS AND METHODS: A retrospective series of 21 cases of nephrogenic adenoma in 18 patients, which were diagnosed in our department between 2010 and 2016, were analyzed...
