Innovations in indwelling urethral catheterisation.

The indwelling urethral catheter remains an integral part of contemporary medical care, despite its significant design shortcomings. Urethral catheterisation is responsible for well-recognised complications including catheter-associated urinary tract infection (CAUTI), catheter-associated urethral injury (CAUI), catheter blockage, and bladder mucosal irritation. In this narrative review, we provide an update on current innovations in urethral catheter design, aimed at safeguarding against these complications. There is an obvious need to improve catheter technology and urologists should support the translation of innovations into clinical practice.

Analysis of a 7-year national online audit of the management of open reconstructive urethral surgery in men.

OBJECTIVE: To conduct an audit of the management of urethral pathology in men presenting for reconstructive urethral surgery in the UK. METHODS: Between 1 June 2010 and 31 May 2017, data on men presenting with urethral pathologies requiring reconstruction were entered onto a secure online data platform. Surgeon-entered information was collected in 95 fields regarding the stricture aetiology, prior management, mode of presentation, type of surgery and outcomes, with a potential 283 variable responses in the 95 fields. Data were analysed to compare UK practice with that reported in the contemporary literature and with guidelines. RESULTS: Data on 4809 men were entered by 39 centres and 50 surgeons. Field completeness was 70.7%, 74.3% and 53.7% for preoperative, operative and follow-up data, respectively. Referral for stricture reconstruction frequently followed two prior endoscopic procedures and the stricture was not always assessed anatomically before surgery. Urinary retention was a common symptom in men awaiting reconstruction. Short unifocal strictures of the anterior urethra were the commonest reason for referral, whilst lichen sclerosus and hypospadias generated a significant volume of revisional stricture surgery. Lower numbers of very complex interventions are required for the management of posterior urethral pathology. Although precise criteria for determining success are not clear, management of urethral reconstruction in the UK was found to have a low risk of Clavien-Dindo grade 3 or higher complications, and was associated with outcomes similar to those reported in contemporary series except in the management of posterior urethral fistulae. CONCLUSIONS: Online databases can provide volume data on the management of reconstructive urethral surgery across a multiplicity of centres in one country. They can also indicate compliance with accepted standards of, and expected outcomes from, this tertiary practice.

Rectourethral Fistulas Secondary to Prostate Cancer Treatment: Management and Outcomes from a Multi-Institutional Combined Experience.

PURPOSE: Rectourethral fistula is a known complication of prostate cancer treatment. Reports in the literature on rectourethral fistula repair technique and outcomes are limited to single institution series. We examined the variations in technique and outcomes of rectourethral fistula repair in a multi-institutional setting. MATERIALS AND METHODS: We retrospectively identified patients who underwent rectourethral fistula repair after prostate cancer treatment at 1 of 4 large volume reconstructive urology centers, including University of California-San Francisco, University College London Hospitals, Lahey Clinic and Devine-Jordan Center for Reconstructive Surgery, in a 15-year period. We examined the types of prostate cancer treatment, technical aspects of rectourethral fistula repair and outcomes. RESULTS: After prostate cancer treatment 201 patients underwent rectourethral fistula repair. The fistula developed in 97 men (48.2%) after radical prostatectomy alone and in 104 (51.8%) who received a form of energy ablation. In the ablation group 84% of patients underwent bowel diversion before rectourethral fistula repair compared to 65% in the prostatectomy group. An interposition flap or graft was placed in 91% and 92% of the 2 groups, respectively. Concomitant bladder neck contracture or urethral stricture developed in 26% of patients in the ablation group and in 14% in the prostatectomy group. Postoperatively the rates of urinary incontinence and complications were higher in the energy ablation group at 35% and 25% vs 16% and 11%, respectively. The ultimate success rate of fistula repair in the energy ablation and radical prostatectomy groups was 87% and 99% with 92% overall success. CONCLUSIONS: Rectourethral fistulas due to prostate cancer therapy can be reconstructed successfully in a high percent of patients. This avoids permanent urinary diversion in these complex cases.

Fistulation into the Pubic Symphysis after Treatment of Prostate Cancer: An Important and Surgically Correctable Complication.

PURPOSE: Chronic pubic pain after the treatment of prostate cancer is often attributed to osteitis pubis. We have become aware of another complication, namely fistulation into the pubic symphysis, which is more serious and more common than previously thought. MATERIALS AND METHODS: A total of 16 patients were treated for urosymphyseal fistulas after the treatment of prostate cancer between January 2011 and April 2014. Clinical presentation was characterized by chronic, debilitating pubic/pelvic/groin pain in all patients. Diagnosis was confirmed by magnetic resonance imaging. Conservative management was successful in only 1 patient. The remaining patients were treated surgically with excision of the fistulous track and involved symphyseal bone and omentoplasty, followed by reconstruction when feasible. RESULTS: All 16 patients had had radiotherapy as primary treatment (8) or after prostatectomy (8). There were 5 patients (31.3%) who underwent various combinations of brachytherapy, external beam radiotherapy and cryotherapy. Bladder neck contractures developed in 13 patients (81.3%), whose treatment (endoscopic or open reconstruction) resulted in urinary leak leading to urosymphyseal fistulas. Reconstruction was possible in 7 of 15 patients (46.7%) with salvage radical prostatectomy and substitution/augmentation cystoplasty. The other 8 patients (53.3%) underwent cystectomy and ileal conduit diversion. All patients experienced resolution of symptoms, most significantly the almost immediate resolution of pain. CONCLUSIONS: A high index of suspicion must be maintained in irradiated patients presenting with symptoms suggestive of urosymphyseal fistulas, especially after having undergone treatment of bladder neck contractures or prostatic urethral stenoses. Although extensive, surgery for urosymphyseal fistulas, with a high risk of morbidity and mortality and a protracted recovery, leads to immediate and dramatic improvement in symptoms.

Urethral atrophy after implantation of an artificial urinary sphincter: fact or fiction?

OBJECTIVES: To investigate the concept of 'urethral atrophy', which is often cited as a cause of recurrent incontinence after initially successful implantation of an artificial urinary sphincter (AUS); and to investigate the specific cause of the malfunction of the AUS in these patients and address their management. PATIENTS AND METHODS: Between January 2006 and May 2013, 50 consecutive patients (mean age 54.3 years) with recurrent incontinence had their AUS explored for malfunction and replaced with a new device with components of exactly the same size, unless there was a particular reason to use something different. Average time to replacement of the device was 10.1 years. The mean follow-up after replacement of the device was 24.7 months. All patients without an obvious cause for their recurrent incontinence had preoperative urodynamic evaluation, including measurement of the Valsalva leak point pressure (VLPP) and the retrograde cuff occlusion pressure (RCOP). After explantation of the AUS in patients without any apparent abnormality of the device at the time of replacement, the pressure generated by the explanted pressure-regulating balloon (PRB) was measured manometrically, when this was possible. In a select group of six consecutive patients of this type, the fibrous capsule surrounding the old cuff was incised then excised to expose and evaluate the underlying corpus spongiosum. RESULTS: In 31 of the 50 patients (62%) undergoing exploration, a specific cause for the malfunction of their AUS was defined. In the other 19 patients (38%) no cause was found, either preoperatively or at the time of exploration, other than a low VLPP and RCOP. A typical 'waisted' or 'hour-glass' appearance of the underlying corpus spongiosum was demonstrable, to some degree, on explanting the cuff in all cases. In the six patients in whom the restrictive sheath surrounding the cuff was excised, the urethral circumference immediately returned to normal after the compressive effect of the sheath was released. Manometry of the explanted PRBs, when this was possible, showed a loss of pressure in all instances. Replacement of the explanted AUS with a new device with the same size cuff and PRB in 14 of these 19 patients was successful in 12 (85.7%). CONCLUSIONS: These results, and other theoretical considerations, suggest that recurrent incontinence, years after initially successful implantation of an AUS, is because of material failure of the PRB, probably attributable to its age and consequent loss of its ability to generate the pressure it was designed to produce, and that urethral atrophy does not occur. Simply replacing the old device with a new one with the same characteristics, unless there is a particular reason to do otherwise, is usually successful and avoids the complications of alternatives such as as cuff downsizing, implanting a PRB with a higher pressure range, implantation of a second cuff or transcorporeal cuff placement, all of which have been advocated in these patients.

Intermittent self-dilatation for urethral stricture disease in males: A systematic review and meta-analysis.

BACKGROUND: Intermittent self-dilatation (ISD) may be recommended to reduce the risk of recurrent urethral stricture. Level one evidence to support the use of this intervention is lacking. OBJECTIVES: Determine the clinical and cost-effectiveness of ISD for the management of urethral stricture disease in males. SEARCH METHODS: The strategy developed for the Cochrane Incontinence Review Group as a whole (last searched May 7, 2014). SELECTION CRITERIA: Randomised trials where one arm was a programme of ISD for urethral stricture. DATA COLLECTION AND ANALYSIS: At least two independent review authors carried out trial assessment, selection, and data abstraction. RESULTS: Data from six trials that were pooled and collectively rated very low quality per the GRADE approach, indicated that recurrent urethral stricture was less likely in men who performed ISD than those who did not (RR 0.70, 95% CI 0.48-1.00). Two trials compared programmes of ISD but the data were not combined and neither were sufficiently robust to draw firm conclusions. Three trials compared devices for performing ISD, results from one of which were too uncertain to determine the effects of a low friction hydrophilic catheter versus a polyvinyl chloride catheter on risk of recurrent urethral stricture (RR 0.32, 95% CI 0.07 to 1.40); another did not find evidence of a difference between 1% triamcinolone gel for lubricating the ISD catheter versus water-based gel on risk of recurrent urethral stricture (RR 0.68, 95% CI 0.35 to 1.32). No trials gave cost-effectiveness or validated PRO data. CONCLUSIONS: ISD may decrease the risk of recurrent urethral stricture. A well-designed RCT is required to determine whether that benefit alone is sufficient to make this intervention worthwhile and in whom. Neurourol.

Surgical correction of bladder neck contracture following prostate cancer treatment.

The surgical and non-surgical treatment of localised prostate cancer may be complicated by bladder neck contractures, prostatic urethral stenoses and bulbomembranous urethral strictures. In general, such complications following radical prostatectomy are less extensive, easier to treat and associated with a better outcome and more rapid recovery than the same complications following radiotherapy, high-intensity focussed ultrasound and cryotherapy. Treatment options range from minimally invasive endoscopic procedures to more complex and specialised open surgical reconstruction.In this chapter the surgical management of bladder neck contractures following the treatment of prostate cancer is described together with the management of prostatic urethral stenoses and bulbomembranous urethral strictures, given the difficulty in distinguishing them from one another clinically.

Experimental evaluation of an electromechanical artificial urinary sphincter in an animal model.

UNLABELLED: What's known on the subject? and what does the study add?: The AMS 800 urinary control system is the gold standard for the treatment of urinary incontinence due to sphincter insufficiency. Despite excellent functional outcome and latest technological improvements, the revision rate remains significant. To overcome the shortcomings of the current device, we developed a modern electromechanical artificial urinary sphincter. The results demonstrated that this new sphincter is effective and well tolerated up to 3 months. This preliminary study represents a first step in the clinical application of novel technologies and an alternative compression mechanism to the urethra. OBJECTIVES: To evaluate the effectiveness in continence achievement of a new electromechanical artificial urinary sphincter (emAUS) in an animal model. To assess urethral response and animal general response to short-term and mid-term activation of the emAUS. MATERIALS AND METHODS: The principle of the emAUS is electromechanical induction of alternating compression of successive segments of the urethra by a series of cuffs activated by artificial muscles. Between February 2009 and May 2010 the emAUS was implanted in 17 sheep divided into three groups. The first phase aimed to measure bladder leak point pressure during the activation of the device. The second and third phases aimed to assess tissue response to the presence of the device after 2-9 weeks and after 3 months respectively. Histopathological and immunohistochemistry evaluation of the urethra was performed. RESULTS: Bladder leak point pressure was measured at levels between 1091 ± 30.6 cmH2 O and 1244.1 ± 99 cmH2 O (mean ± standard deviation) depending on the number of cuffs used. At gross examination, the explanted urethra showed no sign of infection, atrophy or stricture. On microscopic examination no significant difference in structure was found between urethral structure surrounded by a cuff and control urethra. In the peripheral tissues, the implanted material elicited a chronic foreign body reaction. Apart from one case, specimens did not show significant presence of lymphocytes, polymorphonuclear leucocytes, necrosis or cell degeneration. Immunohistochemistry confirmed the absence of macrophages in the samples. CONCLUSIONS: This animal study shows that the emAUS can provide continence. This new electronic controlled sequential alternating compression mechanism can avoid damage to urethral vascularity, at least up to 3 months after implantation. After this positive proof of concept, long-term studies are needed before clinical application could be considered.

Non-transecting anastomotic bulbar urethroplasty: a preliminary report.

OBJECTIVE: To report our early experience with a novel approach to the excision and end-to-end anastomotic repair of bulbar urethral strictures. PATIENTS AND METHODS: A total of 22 patients underwent excision and end-to-end anastomosis of a proximal bulbar urethral stricture using a technique in which the corpus spongiosum is not transected, so as to maintain its blood supply intact. The range of follow-up was 6-21 months and for 16 patients the follow up was ≥1 year. RESULTS: At 1 year of follow-up there was no evidence of a recurrent stricture on symptomatic assessment or uroflowmetry in the 16 patients. On urethrography one patient has a urethral calibre 80% of normal. In the other 15 the calibre is normal or greater than normal. CONCLUSION: The non-transecting anastomotic bulbar urethroplasty technique used appears to give results that are as good as those of traditional anastomotic urethroplasty with less surgical trauma.

Posterior urethral complications of the treatment of prostate cancer.

• To review the less common and not widely discussed, but much more serious complications of prostate cancer treatment of: urethral stricture, bladder neck contracture and urorectal fistula. • The treatment options for patients with organ-confirmed prostate cancer include: radical prostatectomy (RP), brachytherapy (BT), external beam radiotherapy (EBRT), high-intensity focussed ultrasound (HIFU) and cryotherapy; with each method or combination of methods having associated complications. • Complications resulting from RP are relatively easy to manage, with rapid recovery and return to normal activities, and usually a return to normal bodily functions. • However, after non-surgical treatments, i.e. BT, EBRT, HIFU and cryotherapy, these same problems are more difficult to treat with a much slower return to a much lower level of function. • When counselling patients about the primary treatment of prostate cancer they should be advised that although the same type of complication may occur after surgical or non-surgical treatment, the scope and scale of that complication, the ease with which it is treated and the degree of restoration of normality after treatment, is altogether in favour of surgery in those for whom surgery is appropriate and who are fit for surgery.

Urethral strictures.

What's known on the subject? and What does the study add? Urethral strictures are common and increasingly common in an ageing population. The treatment is controversial and particularly the relative roles of urethrotomy or urethral dilatation on the one hand and urethroplasty on the other. This review aims to provide a comprehensive overview of the subject including less commonly discussed issues such as the history and pathology of stricture disease. We would hope that a comprehensive overview of the subject will give a sharper perspective to aid the investigation and management of patients with urethral strictures.

Urorectal fistulae following the treatment of prostate cancer.

UNLABELLED: Study Type--Therapy (case series) Level of Evidence 4. What's known on the subject? and What does the study add? It is known that urorectal fistulae is a serious but rare complication of the treatment of carcinoma of the prostate. This study adds a distinction between post-surgical fistulate and post-irradiation fistulae. Essentially most post-surgical fistulae are simple and relatively easily dealt with: the expectation is that the patient will return to normality; whereas post-irradiation fistulate are by their nature complex and much more difficult to treat with a much more uncertain long-term outcome. Complexity is discussed and defined. OBJECTIVE: • To evaluate the management of urorectal fistulae (URF) in light of new technology in prostate cancer treatment, which has changed the nature of these URF and, therefore, the approach to treatment. PATIENTS AND METHODS: • Between 2004 and 2009 we repaired URF after treatment for prostate cancer in 40 patients with a minimum of 1-year follow-up since their last intervention. • In 23 patients (post-surgical group) the URF resulted from open, laparoscopic or robotic radical prostatectomy. In the other 17 patients (post-irradiation group) the URF resulted from either external beam radiation (EBRT) or brachytherapy (BT), or both, salvage cryotherapy or salvage high-intensity focused ultrasound (sHIFU). • In the 23 patients in the post-surgical group a transperineal repair was performed. In the post-irradiation group a transperineal repair was performed in three of the 17 patients. A transabdominal or abdominoperineal repair was performed in the remaining 14 patients, combined with salvage radical prostatectomy in those eight patients in whom a discrete prostate still existed, and in whom this was possible. RESULTS: • The URF were cured in all patients. • A bladder-neck contracture (BNC) developed in two patients, one of whom is being managed by interval dilatation and the other of whom had a revision of his vesico-urethral anastomosis. Sphincter weakness incontinence required further treatment in eight patients by implantation of an artificial urinary sphincter. • A specific category of complex URF with cavitation was identified, which is particularly common after sHIFU following the combination of previous EBRT and BT, but which may result from the sequential application of any 'new technology'. CONCLUSIONS: • URF of any degree of complexity can be managed without the need for a transanorectal sphincter-splitting approach or a covering colostomy and without the need for an interposition flap when the circumstances are appropriate and the surgeon is sufficiently experienced. URF with cavitation and in the post-irradiation group are an exception and do require an interposition flap. • The role of salvage radical prostatectomy in patients with a URF who still have a prostate, needs to be defined. • We suggest that cavitation, BNC and extensive ischaemia due to the serial application of external energy sources confer 'complexity'. Post-surgical URF are simple except for those with cavitation or a BNC. Most post-irradiation URF are complex even in the absence of cavitation or a BNC.

What's new in urethroplasty?

PURPOSE OF REVIEW: This study provides an overview of current thinking about urethroplasty. RECENT FINDINGS: There have been a number of recent developments, principally to minimize the trauma of anterior urethroplasty and to address the posterior urethral complications of the treatment of prostate cancer. There also have been significant developments in the assessment of the outcome of urethroplasty and specifically of patient reported outcome measures. SUMMARY: These trends are likely to continue. There also seems to be a real possibility that cell culture techniques may finally produce clinically useful material for surgical practice.

Outcomes of a Noninferiority Randomised Controlled Trial of Surgery for Men with Urodynamic Stress Incontinence After Prostate Surgery (MASTER).

BACKGROUND: Stress urinary incontinence (SUI) is common after radical prostatectomy and likely to persist despite conservative treatment. The sling is an emerging operation for persistent SUI, but randomised controlled trial (RCT) comparison with the established artificial urinary sphincter (AUS) is lacking. OBJECTIVE: To compare the outcomes of surgery in men with bothersome urodynamic SUI after prostate surgery. DESIGN, SETTING, AND PARTICIPANTS: A noninferiority RCT was conducted among men with bothersome urodynamic SUI from 27 UK centres. Blinding was not possible due the surgeries. INTERVENTION: Participants were randomly assigned (1:1) to the male transobturator sling (n = 190) or the AUS (n = 190) group. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: The primary outcome was patient-reported SUI 12 mo after randomisation, collected from postal questionnaire using a composite outcome from two items in validated International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form questionnaire (ICIQ-UI SF). Noninferiority margin was 15%, thought to be of acceptable lower effectiveness, in return for reduced adverse events (AEs) and easier operation, for the sling. Secondary outcomes were operative and postoperative details, patient-reported measures, and AEs, up to 12 mo after surgery. RESULTS AND LIMITATIONS: A total of 380 participants were included. At 12 mo after randomisation, incontinence rates were 134/154 (87.0%) for male sling versus 133/158 (84.2%) for AUS (difference 3.6% [95% confidence interval {CI} -11.6 to 4.6], pNI = 0.003), showing noninferiority. Incontinence symptoms (ICIQ-UI SF) reduced from scores of 16.1 and 16.4 at baseline to 8.7 and 7.5 for male sling and AUS, respectively (mean difference 1.4 [95% CI 0.2-2.6], p =  0.02). Serious AEs (SAEs) were few: n = 6 and n = 13 for male sling and AUS (one man had three SAEs), respectively. Quality of life scores improved, and satisfaction was high in both groups. All other secondary outcomes that show statistically significant differences favour the AUS. CONCLUSIONS: Using a strict definition, urinary incontinence rates remained high, with no evidence of difference between male sling and AUS. Symptoms and quality of life improved significantly in both groups, and men were generally satisfied with both procedures. Overall, secondary and post hoc analyses were in favour of AUS. PATIENT SUMMARY: Urinary incontinence after prostatectomy has considerable effect on men's quality of life. MASTER shows that if surgery is needed, both surgical options result in fewer symptoms and high satisfaction, despite most men not being completely dry. However, most other results indicate that men having an artificial urinary sphincter have better outcomes than those who have a sling.

Pelvic fracture-related injuries of the bladder neck and prostate: their nature, cause and management.

OBJECTIVE: To report our experience of bladder neck injuries, which are a well recognized but rare consequence of pelvic fracture-related trauma to the lower urinary tract, as we have been unable to find any reference in the English literature to their specific nature, cause and management in adults. PATIENTS AND METHODS: In the last 10 years we have treated 15 men with bladder neck injuries after pelvic fracture. Two were treated at our centre by delayed primary repair. Thirteen were initially treated elsewhere and presented to us 3 months to 5 years after their injury with intractable incontinence and various other symptoms most notably recurrent urinary infection and gross haematuria. Twelve of the injuries were at or close to the anterior midline and associated with lateral compression fractures or 'open-book' injuries. Five of them were confined to the bladder neck and prostatic urethra; the other seven extended into the subprostatic urethra. Four of these were associated with a coincidental typical rupture of the posterior urethra. All had an associated cavity involving the anterior disruption of the pelvic ring. Two of the injuries, following particularly severe trauma, were a simultaneous complete transection of the bladder neck and of the bulbo-membranous urethra with a sequestered prostate between. We have seen this in children before but not in adults. Another injury, also after particularly severe trauma, was an avulsion of the anterior aspect of the prostate. We have not seen this described before. Fourteen patients underwent lower urinary tract reconstruction and one underwent a Mitrofanoff procedure. All of the 14 had a layered reconstruction of the prostate and bladder neck and in 13, this was supplemented with an omental wrap. RESULTS: In all patients with an anterior midline rupture, the primary injury appeared to be to the prostate and prostatic urethra with secondary involvement of the bladder neck and the subprostatic urethra. The Mitrofanoff procedure was successful. Of the 14 patients with a layered reconstruction one, without an omental wrap, broke down but was successfully repaired on a subsequent occasion. The four patients who also had a ruptured urethra had a simultaneous bulbo-prostatic anastomotic urethroplasty, two of which required further attention. Eight of the 14 reconstructed patients underwent implantation of an artificial urinary sphincter (AUS) for sphincter weakness incontinence, in seven of whom this was successful. Two of these had previously undergone implantation of an AUS with an unsatisfactory outcome and were made continent by bladder neck reconstruction. The other six patients had acceptable urinary incontinence by reconstruction of the bladder neck and urethra alone. CONCLUSIONS: The primary injury is to the prostate and prostatic urethra. The bladder neck and subprostatic urethra are involved secondarily by extension. These injuries have a particular cause and a particular location with a predictable outcome. They need to be identified and treated promptly as they do not heal spontaneously and otherwise cause considerable morbidity. We also describe two particular types of bladder neck injury that we have not seen described before in adults.

A Fellowship programme in reconstructive urological surgery: what is it and what is it for?

OBJECTIVE: To report our experience of a 3-year Fellowship in reconstructive urology for its content and duration, with particular reference to what can be achieved each year. METHODS: Over the 3-year period October 2004 to October 2007 the Fellow worked full-time in a specialist reconstructive urological centre as principal assistant to the trainer in the care of outpatients and inpatients, and in the performance of the various surgical procedures. Using a prospectively constructed logbook it was possible to compare the developing surgical experience of the Fellow in terms of both the frequency and complexity of the cases undertaken and the surgical outcomes, compared with similar data for the trainer. RESULTS: Over the 3-year period the Fellow progressively took on more cases and of increasing complexity, and the trainer progressively adopted the role of assistant, except for particularly complex cases. Throughout this period the complication rate of the trainer and the Fellow remained the same. CONCLUSIONS: Even at the end of 3 years the Fellow was still limited in what she could deal with as an independent practitioner. Fellowship training should be goal directed in content and duration, and based around hands-on experience.

Entero-urethroplasty for the salvage of bulbo-membranous stricture disease or trauma.

OBJECTIVE: To describe a salvage procedure for bulbo-membranous stricture disease or trauma. PATIENTS AND METHODS: Over a 10-year period 11 patients with otherwise unsalvageable strictures of the bulbo-membranous urethra or defects after trauma were treated by interposition of a tailored intestinal flap. An intestinal flap, on average 8 cm in length, was harvested from the ileum, the stomach, the right colon or (preferably) the sigmoid colon, and tailored to a calibre of 26-30 F. It was then sutured between the stump of the prostate and the distal bulbar or proximal pendulous urethra either following the normal perineal route for the urethra or a more direct route through a trench cut in the superior pubic ramus. RESULTS: Three patients developed proximal anastomotic contractures requiring interval dilatation in one and revision in two. Two patients developed a stone in the gut segment one of which was removed traumatically causing irreparable damage to the neourethra. The results were otherwise satisfactory. CONCLUSION: For an otherwise unsalvageable bulbo-membranous stricture or defect, a tailored flap of intestine, preferably sigmoid colon, gives satisfactory results. Of the two potential routes for the neourethra, we have more experience with the normal route but the direct route has several advantages.

Syringoceles of Cowper's ducts and glands in adult men.

Cowper's syringoceles are uncommon, usually described in children and most commonly limited to the ducts. We describe more complex variants in an adult population affecting with varying degrees of severity, the glands themselves, and the complications they may lead to. One hundred consecutive urethrograms of patients with unreconstructed strictures were reviewed. Twenty-six patients (mean age: 41.1 years) with Cowper's syringoceles who were managed between 2009 and 2016 were subsequently evaluated. Presentation, radiological appearance, treatment (when indicated), and outcomes were assessed. Of 100 urethrograms in patients with strictures, 33.0% demonstrated filling of Cowper's ducts or glands, occurring predominantly in patients with bulbar strictures. Only 1 of 26 patients with non-bulbar strictures had a visible duct/gland. Of 26 symptomatic patients, 15 presented with poor flow. In four patients, a grossly dilated Cowper's duct obstructed the urethra. In the remaining 11 patients, a bulbar stricture caused the symptoms and the syringocele was identified incidentally. Eight patients presented with perineal pain. In six of them, fluoroscopy and magnetic resonance imaging (MRI) revealed complex multicystic lesions within the bulbourethral glands. Four patients developed perineoscrotal abscesses. In the 11 patients with strictures, the syringocele was no longer visible after urethroplasty. In three of four patients with urethral obstruction secondary to a dilated Cowper's duct, this resolved after transperineal excision (n = 2) and endoscopic deroofing (n = 1). Five of six patients with complex syringoceles involving Cowper's glands were excised surgically with symptomatic relief in all. In conclusion, Cowper's syringocele in adults is more common than previously thought and may cause lower urinary tract symptoms or be associated with serious complications which usually require surgical treatment.

Single-stage tubular urethral reconstruction using oral grafts is an alternative to classical staged approach for selected penile urethral strictures.

Penile urethral strictures have been managed by a staged surgical approach. In selected cases, spongiofibrosis can be excised, a neo-urethral plate created using buccal mucosa graft (BMG) and tubularized during the same procedure, performing a "two-in-one" stage approach. We aim to identify stricture factors which indicate suitability for this two-in-one stage approach. We assess surgical outcome and compare with staged reconstruction. We conducted an observational descriptive study. The data were prospectively collected from two-in-one stage and staged penile urethroplasties using BMG in a single center between 2007 and 2017. The minimum follow-up was 6 months. Outcomes were assessed clinically, radiologically, and by flow-rate analysis. Failure was defined as recurrent stricture or any subsequent surgical or endoscopic intervention. Descriptive analysis of stricture characteristics and statistical comparison was made between groups. Of 425 penile urethroplasties, 139 met the inclusion criteria: 59 two-in-one stage and 80 staged. The mean stricture length was 2.8 cm (single stage) and 4.5 cm (staged). Etiology was lichen sclerosus (LS) 52.5% (single stage) and 73.8% hypospadias related (staged). 40.7% of patients had previous failed urethroplasties in the single-stage group and 81.2% in the staged. The most common stricture locations were navicular fossa (39.0%) and distal penile urethra (59.3%) in the single-stage group and mid or proximal penile urethra (58.7%) in the staged group. Success rates were 89.8% (single stage) and 81.3% (staged). A trend toward a single-stage approach for select penile urethral strictures was noted. We conclude that a single-stage substitution penile urethroplasty using BMG as a "two-in-one" approach is associated with excellent functional outcomes. The most suitable strictures for this approach are distal, primary, and LS-related strictures.

Surgical Treatment for Recurrent Bulbar Urethral Stricture: A Randomised Open-label Superiority Trial of Open Urethroplasty Versus Endoscopic Urethrotomy (the OPEN Trial).

BACKGROUND: Urethral stricture affects 0.9% of men. Initial treatment is urethrotomy. Approximately, half of the strictures recur within 4 yr. Options for further treatment are repeat urethrotomy or open urethroplasty. OBJECTIVE: To compare the effectiveness and cost-effectiveness of urethrotomy with open urethroplasty in adult men with recurrent bulbar urethral stricture. DESIGN, SETTING, AND PARTICIPANTS: This was an open label, two-arm, patient-randomised controlled trial. UK National Health Service hospitals were recruited and 222 men were randomised to receive urethroplasty or urethrotomy. INTERVENTION: Urethrotomy is a minimally invasive technique whereby the narrowed area is progressively widened by cutting the scar tissue with a steel blade mounted on a urethroscope. Urethroplasty is a more invasive surgery to reconstruct the narrowed area. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: The primary outcome was the profile over 24 mo of a patient-reported outcome measure, the voiding symptom score. The main clinical outcome was time until reintervention. RESULTS AND LIMITATIONS: The primary analysis included 69 (63%) and 90 (81%) of those allocated to urethroplasty and urethrotomy, respectively. The mean difference between the urethroplasty and urethrotomy groups was -0.36 (95% confidence interval [CI] -1.74 to 1.02). Fifteen men allocated to urethroplasty needed a reintervention compared with 29 allocated to urethrotomy (hazard ratio [95% CI] 0.52 [0.31-0.89]). CONCLUSIONS: In men with recurrent bulbar urethral stricture, both urethroplasty and urethrotomy improved voiding symptoms. The benefit lasted longer for urethroplasty. PATIENT SUMMARY: There was uncertainty about the best treatment for men with recurrent bulbar urethral stricture. We randomised men to receive one of the following two treatment options: urethrotomy and urethroplasty. At the end of the study, both treatments resulted in similar and better symptom scores. However, the urethroplasty group had fewer reinterventions.
