Dirk K, Rourke KF. Health-related Quality of Life in Patients With Urethral Stenosis After Radiation Treatment for Prostate Cancer. Urology 2024; 185:109-115. [PMID: 38160763 DOI: 10.1016/j.urology.2023.10.041] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/28/2023] [Revised: 10/23/2023] [Accepted: 10/25/2023] [Indexed: 01/03/2024]
Abstract
OBJECTIVE To evaluate patient-reported quality of life (PRQoL) in patients presenting with membranous urethral stenosis after prostate radiotherapy. Urethral stenosis is an under-reported complication after prostate radiotherapy with a particular deficiency in PRQoL. METHODS Patients presenting with urethral stenosis after radiotherapy were retrospectively reviewed from 2004 to 2022. PRQoL was assessed via patient survey using the Expanded Prostate Cancer Index Composite for Clinical Practice (EPIC-CP). RESULTS Two hundred thirty patients were identified at a mean age of 67.7years and mean time to stricture diagnosis of 63.6months' postradiotherapy. Of 87 patients completing the survey, 29.9% recalled being aware of urethral stenosis as a potential complication and 51.7% had documentation of urethral stenosis as a potential complication. 33.5% of patients underwent urethroplasty, 59.6% repeat endoscopic treatment and 6.1% an indwelling catheter. 64.4% of patients reported urinary dysfunction as a "moderate" or "big" problem, 66.7% reported frequent or total incontinence, 64.4% required daily pad use and 50.6% reported incontinence as either a "moderate" or "big" problem. 85.0% reported poor or absent orgasmic dysfunction and 88.5% reported erections insufficient for sexual activity. Additionally, 47.1% of patients reported rectal pain and 31.0% reported dysuria. Depressive symptoms and fatigue were reported by 41.4% and 60.9% of patients respectively. CONCLUSION Urethral stenosis after radiotherapy is a clinically complex entity with a broad scope of associated symptoms including high rates of patient-reported incontinence, voiding dysfunction, sexual dysfunction, pain, bowel dysfunction and depression. This multifocal nature combined with often insidious presentation and patient unawareness creates a uniquely challenging condition to treat.

World J Urol 2023; 41:1905-1912. [PMID: 37314572 PMCID: PMC10352169 DOI: 10.1007/s00345-023-04429-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/16/2023] [Accepted: 04/18/2023] [Indexed: 06/15/2023] Open
Abstract
PURPOSE To analyze patients who underwent anastomotic urethroplasty for radiationinduced bulbomembranous urethral stricture/stenosis (RIS) due to prostate cancer treatment with up to 19 years of follow-up and assess long-term patient reported outcomes (PROMs). Long-term follow-up with the inclusion of urethroplasty specific PROMs is lacking in the available research. METHODS Patients who underwent anastomotic urethroplasty for RIS were identified from 2002 to 2020. Inclusion criteria included completion of 4-month post-operative cystoscopy and PROMs including IPSS, SHIM, MSHQ-EF, 6Q-LUTS, and global satisfaction queries at 4 months. PROMs were assessed annually thereafter, and cystoscopy was performed for adverse change in PROMs or worsening uroflow/PVR parameters. PROMs were compared at pre-op, post-op, and most recent follow-up. RESULTS 23 patients met inclusion criteria. Short-term anatomic success was 95.7%. At a mean follow-up of 73.1 months (9.1-228.9), one late recurrence occurred for an overall success of 91.3%. Significant and sustained objective improvement was identified in voiding scores, quality of life, and urethroplasty specific PROMs. Satisfaction was 91.3% despite sexual side effects, and 95.7% of patients stated they would have surgery again knowing their outcome at a mean of over 6 years' follow up. CONCLUSIONS RIS are challenging problems, but durable symptomatic relief is achievable in well-selected patients. Patients with bulbomembranous RIS should be appropriately counseled regarding the risk of urinary incontinence and sexual side effects after anastomotic urethroplasty. However, long-term success is high, and overall QoL will have sustained subjective improvement in most cases.

Abstract
Radiation therapy (RT) in the management of pelvic cancers remains a clinical challenge to urologists given the sequelae of urethral stricture disease secondary to fibrosis and vascular insults. The objective of this review is to understand the physiology of radiation-induced stricture disease and to educate urologists in clinical practice regarding future prospective options clinicians have to deal with this condition. The management of post-radiation urethral stricture consists of conservative, endoscopic, and primary reconstructive options. Endoscopic approaches remain an option, but with limited long-term success. Despite concerns with graft take, reconstructive options such as urethroplasties in this population with buccal grafts have shown long-term success rates ranging from 70 to 100%. Robotic reconstruction is augmenting previous options with faster recovery times. Radiation-induced stricture disease is challenging with multiple interventions available, but with successful outcomes demonstrated in various cohorts including urethroplasties with buccal grafts and robotic reconstruction.

Abstract
Radiation is a common treatment modality for pelvic malignancies. While it can be effective at cancer control, downstream effects can manifest months to years after treatment, leaving patients with significant morbidity. Within urology, a particularly difficult post-radiation consequence is urinary tract stricture, either of the urethra, bladder neck, or ureter. In this review, we will discuss the mechanism of radiation damage and treatment options for these potentially devastating urinary sequelae.

Abstract
Bladder outlet obstruction following treatment of pelvic cancer, predominantly prostate cancer, occurs in 1-8% of patients. The high incidence of prostate cancer combined with the long-life expectancy after treatment has increased concerns with cancer survivorship care. However, despite increased oncological cure rates, these adverse events do occur, compromising patients' quality of life. Non-traumatic obstruction of the posterior urethra and bladder neck include membranous and prostatic urethral stenosis and bladder neck stenosis (also known as contracture). The devastated bladder outlet can result from benign conditions, such as neurogenic dysfunction, trauma, iatrogenic causes, or more frequently from complications of oncologic treatment, such as prostate, bladder and rectum. Most posterior urethral stenoses may respond to endoluminal treatments such as dilatation, direct vision internal urethrotomy, and occasionally urethral stents. Although surgical reconstruction offers the best chance of durable success, these reconstructive options are fraught with severe complications and, therefore, are far from being ideal. In patients with prior RT, failed reconstruction, densely fibrotic and/or necrotic and calcified posterior urethra, refractory incontinence or severe comorbidities, reconstruction may not be either feasible or recommended. In these cases, urinary diversion with or without cystectomy is usually required. This review aims to discuss the diagnostic evaluation and treatment options for patients with bladder outlet obstruction with a special emphasis on patients unsuitable for reconstruction of the posterior urethra and requiring urinary diversion.

Abstract
OBJECTIVE To describe the technique, feasibility and short-term outcomes of buccal mucosa grafts in robotic lower urinary tract reconstruction. METHODS We reviewed 9 patients who underwent single-port robotic posterior urethroplasty with buccal mucosa graft from May-December 2019. Variables included patient demographics, diagnosis/etiology, and intraoperative parameters. Intraabdominal or extraperitoneal transvesical approaches are used for the stricture via supraumbilical access, and if necessary, perineal dissection is performed. Cystoscopy identifies the extent of stenosis. Anastomosis is completed with buccal mucosal graft and rectus abdominis, omental or gracilis flaps as needed. RESULTS The mean age was 65.4 years. Robotic urethroplasty with buccal mucosa graft was performed for vesicourethral anastomotic strictures (n = 7), urethral strictures (n = 4), pubic fistula after robotic posterior urethroplasty (n = 1), and anastomotic distraction (n = 1). Strictures occurred after prostate cancer treatments (n = 8) and trauma (n = 1). All patients had prior failed endoscopic interventions: balloon dilatation, resection/incision of bladder neck, internal urethrotomy under direct vision, urethral stents, and posterior urethroplasty. Mean defect length was 3.9 cm. Five of 9 patients had ancillary procedures including rectus abdominis (n = 3), omental or gracilis (both n = 1) flap harvests. No intraoperative complications occurred. Median operative time was 377 minutes, blood loss was 200 mL, and length of stay was 2 days. Postoperative 30-day complications included urinary tract infection, epididymitis, anemia, recurrent stricture, and small bowel obstruction requiring surgery (all n = 1). Median follow-up was 11.7 months. CONCLUSION Buccal mucosa grafts with ancillary maneuvers such as flap interposition or adjacent tissue transfer in robotic lower tract reconstruction is durable, safe, and comparable to open approaches.

Multi-Institutional Study of Dorsal Onlay Urethroplasty of the Membranous Urethra after Endoscopic Prostate Procedures: Operative Results, Continence, Erectile Function and Patient Reported Outcomes. J Clin Med 2021; 10:jcm10173969. [PMID: 34501417 PMCID: PMC8432256 DOI: 10.3390/jcm10173969] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/31/2021] [Revised: 08/22/2021] [Accepted: 08/23/2021] [Indexed: 11/16/2022] Open
Abstract
(1) Background: To critically evaluate dorsal onlay buccal mucosal graft urethroplasty (DOBMGU) for posterior urethral stenosis repair following transurethral resection and other endoscopic prostate procedures. (2) Methods: A retrospective multi-institutional review of patients with membranous or bulbomembranous urethral stenosis for whom treatment with DOBMGU was conducted after receipt of prostate endoscopic procedures. Baseline data, peri-operative care, post-operative care and patient-reported outcomes were analyzed. The primary outcomes were procedural failure and development of de novo stress urinary incontinence (SUI). The secondary outcomes were changes in voiding, sexual function and patient satisfaction. (3) Results: A total of 107 men with a mean age of 69 ± 9.5 years and stenosis length of 3.5 ± 1.8 cm were included. Prior endoscopic procedures among participants were 47 patients (44%) with monopolar TURP, 33 (30.8%) with bipolar TURP, 16 (15%) with Greenlight laser, 9 (8.4%) with Holmium laser enucleation and 2 (1.9%) with bladder neck incision. At a mean follow-up time of 59.3 ± 45.1 months, stenosis recurred in 10 patients (9.35%). Multivariate analysis confirmed that postoperative complications (OR 12.5; p = 0.009), history of radiation (OR 8.3; p = 0.016) and ≥2 dilatations before urethroplasty (OR 8.3; p = 0.032) were independent predictors of recurrence. Only one patient (0.9%) developed de novo SUI. Patients experienced significant improvement in PVR (128 to 60 cc; p = 0.001), Uroflow (6.2 to 16.8 cc/s; p = 0.001), SHIM (11.5 to 11.7; p = 0.028), IPSS (20 to 7.7; p < 0.001) and QoL (4.4 to 1.7; p < 0.001), and 87 cases (81.3%) reported a GRA of + 2 or better. (4) Conclusions: DOBMGU is an effective and safe option for patients with posterior urethral stenosis following TURP and other prostate endoscopic procedures. This non-transecting approach minimizes external urinary sphincter manipulation, thus limiting postoperative risk of SUI or erectile dysfunction.

Abstract
OBJECTIVE To present a summary of the 2021 version of the European Association of Urology (EAU) guidelines on management of male urethral stricture disease. EVIDENCE ACQUISITION The panel performed a literature review on these topics covering a time frame between 2008 and 2018, and used predefined inclusion and exclusion criteria for the literature to be selected. Key papers beyond this time period could be included as per panel consensus. A strength rating for each recommendation was added based on a review of the available literature and after panel discussion. EVIDENCE SYNTHESIS Management of male urethral strictures has extensively been described in literature. Nevertheless, few well-designed studies providing high level of evidence are available. In well-resourced countries, iatrogenic injury to the urethra is one of the most common causes of strictures. Asymptomatic strictures do not always need active treatment. Endoluminal treatments can be used for short, nonobliterative strictures at the bulbar and posterior urethra as first-line treatment. Repetitive endoluminal treatments are not curative. Urethroplasty encompasses a multitude of techniques, and adaptation of the technique to the local conditions of the stricture is crucial to obtain durable patency rates. CONCLUSIONS Management of male urethral strictures is complex, and a multitude of techniques are available. Selection of the appropriate technique is crucial, and these guidelines provide relevant recommendations. PATIENT SUMMARY Injury to the urethra by medical interventions is one of the most common reasons of male urethral stricture disease in well-resourced countries. Although different techniques are available to manage urethral strictures, not every technique is appropriate for every type of stricture. These guidelines, developed based on an extensive literature review, aim to guide physicians in the selection of the appropriate technique(s) to treat a specific type of urethral stricture.

Abstract
Radiotherapy is a frequently used treatment for prostate cancer. It does not only causes the intended damage to cancer cells, but also affects healthy surrounding tissue. As a result radiation-induced urethral strictures occur in 2.2% of prostate cancer patients. Management of urethral strictures is challenging due to the presence of poor vascularized tissue for reconstruction and the proximity of the sphincter, which can impair the functional outcome. This review provides a literature overview of risk factors, diagnostics and management of radiation-induced urethral strictures.

Efficacy and Incontinence Rates After Urethroplasty for Radiation-induced Urethral Stenosis: A Systematic Review and Meta-analysis. Urology 2021; 152:109-116. [PMID: 33631205 DOI: 10.1016/j.urology.2021.02.014] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/27/2020] [Revised: 12/30/2020] [Accepted: 02/05/2021] [Indexed: 12/31/2022]
Abstract
OBJECTIVE To estimate the efficacy of urethroplasty and rates of de novo stress urinary incontinence (SUI) in the specific setting of radiation-induced urethral stenosis. METHODS A systematic search of databases (PubMed and EMBASE) was performed between 1980-2019 (CRD42020144845). Inclusion criteria were: (1) prior pelvic radiotherapy; (2) surgical urethroplasty; (3) rates of successful treatment and/or SUI development and (4) total case number provided. The pooled summary of stenosis resolution rate and SUI were calculated using the random-effects model weighted by the inverse variance. Accessory analyses were performed by reconstructive technique and type of RT. RESULTS Ninety-six studies were identified, of which 8 retrospective studies met inclusion criteria, comprising 256 patients. The proportion of cases treated with external beam RT (EBRT), brachytherapy (BT), or combination (EBRT+BT) were 52%, 33%, and 15%, respectively, of studies that specified modality. Most strictures involved the bulbomembranous region (n = 212; 83%). Sixty-one percent of cases (n = 157) entailed primary anastomosis, while the remainder underwent augmentation reconstruction (graft or flap). The mean follow-up time after urethroplasty varied from 10 to 50.5 months. The pooled stenosis resolution rate was 80% (95% CI: 74%-86%). There were no significant associations between stenosis resolution rate and reconstructive technique (rho=0.20, P = .74) or RT modality (rho=-0.31, P = .53). Fifty-three cases developed subsequent SUI, with a pooled complication rate of 19% (95% CI: 10%-31%). CONCLUSIONS Urethroplasty after radiation-induced urethral stenosis is effective for 80% of cases, independent of prior RT modality or urethroplasty technique; however, 1 out of every 5 patients develops SUI post-procedure.

Abstract
OBJECTIVE To evaluate the outcomes of excision and primary anastomosis (EPA) for radiation-associated bulbomembranous stenoses using a multi-institutional analysis. The treatment of radiation-associated urethral stenosis is typically complex owing to the adverse impact of radiation on adjacent tissue. METHODS An IRB-approved multi-institutional retrospective review was performed on patients who underwent EPA for bulbomembranous urethral stenosis following prostate radiotherapy. Preoperative patient demographics, operative technique, and postoperative outcomes were abstracted from 1/2007-6/2018. Success was defined as voiding per urethra without the need for endoscopic treatment and a minimum follow-up of 12 months. RESULTS One hundred and thirty-seven patients from 10 centers met study criteria with a mean age of 69.3 years (50-86), stenosis length of 2.3 cm (1-5) and an 86.9% (119/137) success rate at a mean follow-up 32.3 months (12-118). Univariate Cox regression analysis identified increasing patient age (P = .02), stricture length (P <.0001) and combined modality radiotherapy (P = .004) as factors associated with stricture recurrence while body mass index (P = .79), diabetes (P = .93), smoking (P = .62), failed endoscopic treatment (P = .08) and gracilis muscle use (P = .25) were not. On multivariate analysis, increasing patient age (H.R.1.09, 95%CI 1.01-1.16; P = .02) and stenosis length (H.R.2.62, 95%CI 1.49-4.60; P = .001) remained associated with recurrence. Subsequent artificial urinary sphincter was performed in 30 men (21.9%), of which 25 required a transcorporal cuff and 5 developed cuff erosion. CONCLUSIONS EPA for radiation-associated urethral stenosis effectively provides unobstructed instrumentation-free voiding. However, increasing stenosis length and age are independently associated with surgical failure. Patients should be counseled that further surgery for incontinence may be necessary.

Abstract
PURPOSE To critically evaluate a multi-institutional patient cohort undergoing Dorsal-Onlay Buccal Mucosal Graft Urethroplasty (D-BMGU) for recurrent post-radiation posterior urethral stenosis. METHODS Retrospective multi-institutional review of patients with posterior urethral stenosis from 10 institutions between 2010-2019 was performed. Patients with at least 1-year follow-up were assessed. Patient demographics, stenosis characteristics, peri-operative outcomes, and post-operative clinical and patient-reported outcomes were analyzed. The primary outcomes were stenosis recurrence and de-novo stress urinary incontinence (SUI). Secondary outcomes were changes in voiding, sexual function, and patient-reported satisfaction. RESULTS Seventy-nine men with post-radiation urethral stenosis treated with D-BMGU met inclusion criteria. Median age and stenosis length were 72 years, (IQR 66-75), and 3.0 cm (IQR 2.5-4 cm), respectively. Radiation modalities included: 36 (45.6%) external beam radiotherapy (EBRT), 13 (16.5%) brachytherapy (BT), 10 (12.7%) combination EBRT/BT, and 20 (25.3%) EBRT/radical prostatectomy. At a median follow-up of 21 months (IQR 13-40), 14 patients (17.7%) had stenosis recurrence. Among 37 preoperatively-continent patients, 3 men (8.1%) developed de-novo SUI following dorsal onlay urethroplasty. Of 29 patients with preoperative SUI all but one remained incontinent post-operatively (96.6%). Following repair, patients experienced significant improvement in PVR (92.5 to 26 cc, p = 0.001) and Uroflow (4.6 to 15.9 cc/s, p = 0.001), and high overall satisfaction, with 91.9% reporting a GRA of + 2 or better). CONCLUSION Dorsal onlay buccal mucosa graft urethroplasty is a safe and feasible technique in patients with post-radiation posterior urethral stenosis. This non-transecting approach may confer low rates of de-novo SUI. Further research is needed to compare this technique with excisional urethroplasty.

Abstract
Urethral stricture is fundamentally a fibrosis of the urethral epithelial and associated corpus spongiosum, which in turn, causes obstruction of the urethral lumen. Patients with urethral stricture most commonly present with lower urinary tract symptoms, urinary retention or urinary tract infection but may also experience a broad spectrum of other signs and symptoms, including genitourinary pain, hematuria, abscess, ejaculatory dysfunction, or renal failure. When urethral stricture is initially suspected based on clinical assessment, cystoscopy is suggested as the modality that most accurately establishes the diagnosis. This recommendation is based on several factors, including the accuracy of cystoscopy, as well as its wide availability, lesser overall cost, and comfort of urologists with this technique. When recurrent urethral stricture is suspected, we suggest performing retrograde urethrography to further stage the length and location of the stricture or referring the patient to a physician with expertise in reconstructive urology. Ultimately, the treatment decision depends on several factors, including the type and acuity of patient symptoms, the presence of complications, prior interventions, and the overall impact of the urethral stricture on the patient's quality of life. Endoscopic treatment, either as dilation or internal urethrotomy, is suggested rather than urethroplasty for the initial treatment of urethral stricture. This recommendation applies to men with undifferentiated urethral stricture and does not apply to trauma-related urethral injuries, penile urethral strictures (hypospadias, lichen sclerosus), or suspected urethral malignancy. In the setting of recurrent urethral stricture, urethroplasty is suggested rather than repeat endoscopic management but this may vary depending on patient preference and impact of the symptoms on the patient.The purpose of this guideline is to provide a practical summary outlining the diagnosis and treatment of urethral stricture in the Canadian setting.

Abstract
OBJECTIVES To evaluate objective treatment success and subjective patient-reported outcomes in patients with radiation-induced urethral strictures undergoing single-stage urethroplasty. PATIENTS AND METHODS Monocentric study of patients who underwent single-stage ventral onlay buccal mucosal graft urethroplasty for a radiation-induced stricture between January 2009 and December 2016. Patients were characterized by descriptive analyses. Kaplan-Meier estimates were employed to plot recurrence-free survival. Recurrence was defined as any subsequent urethral instrumentation (dilation, urethrotomy, urethroplasty). Patient-reported functional outcomes were evaluated using the validated German extension of the Urethral Stricture Surgery Patient-Reported Outcome Measure (USS PROM). RESULTS Overall, 47 patients were available for final analyses. Median age was 70 (IQR 65-74). Except for two, all patients had undergone pelvic radiation therapy for prostate cancer. Predominant modality was external beam radiation therapy in 70% of patients. Stricture recurrence rate was 33% at a median follow-up of 44 months (IQR 28-68). In 37 patients with available USS PROM data, mean six-item LUTS score was 7.2 (SD 4.3). Mean ICIQ sum score was 9.8 (SD 5.4). Overall, 53% of patients reported daily leaking and of all, 26% patients underwent subsequent artificial urinary sphincter implantation. Mean IIEF-EF score was 4.4 (SD 7.1), indicating severe erectile dysfunction. In 38 patients with data regarding the generic health status and treatment satisfaction, mean EQ-5D index score and EQ VAS score was 0.91 (SD 0.15) and 65 (SD 21), respectively. Overall, 71% of patients were satisfied with the outcome. CONCLUSION The success rate and functional outcome after BMGU for radiation-induced strictures were reasonable. However, compared to existing long-term data on non-irradiated patients, the outcome is impaired and patients should be counseled accordingly.

Abstract
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.

Abstract
This study aimed to develop an indwelling catheter that can be used for urethral flushing, urethral secretion drainage, local urethral drug delivery, and urine drainage.We designed a new indwelling catheter type that has a balloon, 4 peripheral grooves, and a C-shaped groove on its surface. In addition, there is a flushing channel, a balloon channel, and a urine drainage channel in the catheter body. However, the most critical characteristic is that the flushing channel and the 4 peripheral grooves are connected with the C-shaped groove, and the flushing liquid can reach the C-shaped groove through the flushing channel and then flow out through the peripheral grooves, while the balloon channel leads to the balloon. Generally, our design is to add 4 peripheral grooves, a C-shaped groove, and a flushing channel to the indwelling catheter that is applied clinically nowadays.We designed a new type of indwelling catheter, which is multifunctional, and we had acquired a national patent in China. In theory, the new catheter type cannot only be used for urine drainage, bladder irrigation, but also for urethral flushing, urethral excretion drainage, and local urethral drug delivery at the same time.This new indwelling catheter can theoretically reduce catheter-associated urinary tract infection and facilitate urethral secretion drainage or flushing out, which is especially suitable for the treatment and nursing of patients who underwent urethral operation. However, the new catheter have not been produced and tested clinically, and this is our next step.

Abstract
PURPOSE OF REVIEW Due to the proximity of the rhabdosphincter and cavernous nerves to the membranous urethra, reconstruction of membranous urethral stricture implies a risk of urinary incontinence and erectile dysfunction. To avoid these complications, endoscopic management of membranous urethral strictures is traditionally favored, and bulboprostatic anastomosis is reserved as the main classical approach for open reconstruction of recalcitrant membranous urethral stricture. The preference for the anastomotic urethroplasty among reconstructive urologists is likely influenced by the familiarity and experience with trauma-related injuries. We review the literature focusing on the anatomy of membranous urethra and on the evolution of treatments for membranous urethral strictures. RECENT FINDINGS Non-traumatic strictures affecting bulbomembranous urethra are typically sequelae of instrumentation, transurethral resection of the prostate, prostate cancer treatment, and pelvic irradiation. Being a different entity from trauma-related injuries where urethra is not in continuity, a new understanding of membranous urethral anatomy is necessary for the development of novel reconstruction techniques. Although efficacious and durable to achieve urethral patency, classical bulboprostatic anastomosis carries a risk of de-novo incontinence and impotence. Newer and relatively less invasive reconstructive alternatives include bulbar vessel-sparing intra-sphincteric bulboprostatic anastomosis and buccal mucosa graft augmented membranous urethroplasty techniques. The accumulated experience with these techniques is relatively scarce, but several published series present promising results. These approaches are especially indicated in patients with previous transurethral resection of the prostate in which sparing of rhabdosphincter and the cavernous nerves is important in attempt to preserve continence and potency. Additionally, introduction of buccal mucosa onlay grafts could be especially beneficial in radiation-induced strictures to avoid transection of the sphincter in continent patients, and to preserve the blood supply to the urethra for incontinent patients who will require artificial urinary sphincter placement. The evidence regarding erectile functional outcomes is less solid and this item should be furtherly investigated.

Abstract
PURPOSE OF REVIEW This article discusses the incidence, evaluation, and treatment of bladder outlet obstruction from urethral stricture, vesicourethral anastomotic stricture, and bladder neck contracture following primary and salvage treatment of prostate cancer. RECENT FINDINGS Rates of stenosis after prostate cancer treatment appear similar across all primary treatment modalities including radical prostatectomy, radiation therapy, cryoablation, and high-intensity focused ultrasound in contemporary series. Urethral dilation and urethrotomy continue to report moderate patency rates. Urethroplasty achieves high patency rates even for long strictures, but more extensive reconstruction increases the risk of postoperative urinary incontinence. Recent AUA guidelines on urethral strictures provide new recommendations for management of these patients. All treatment options for prostate cancer carry a risk for bladder outlet obstruction, and intervention is often necessary to relieve long-lasting morbidity. Careful preoperative evaluation should be completed to assess location and extent of the stricture in order to choose optimal therapy. Endoscopic treatments, open reconstruction, and urinary diversion all play a role in relief of stenosis depending on stricture length, location, characteristics, and patient comorbidities.

Abstract
The aim of this review is to examine all urethral strictures and stenoses subsequent to treatment for prostate cancer, including radical prostatectomy (RP), radiotherapy, high intensity focused ultrasound (HIFU) and cryotherapy. The overall majority respond to endoscopic treatment, including dilatation, direct visual internal urethrotomy (DVIU) or bladder neck incision (BNI). There are adjunct treatments to endoscopic management, including injections of corticosteroids and mitomycin C (MMC) and urethral stents, which remain controversial and are not currently mainstay of treatment. Recalcitrant strictures are most commonly managed with urethroplasty, while recalcitrant stenosis is relatively rare yet almost always associated with bothersome urinary incontinence, requiring bladder neck reconstruction and subsequent artificial urinary sphincter (AUS) implantation, or urinary diversion for the devastated outlet.

Abstract
INTRODUCTION Posterior urethral stenoses and contractures are complications after treatment of benign prostatic hyperplasia (BPH), localised prostate cancer (PCa), and orthotopic neobladder formation, compromising prognosis and functional outcomes. OBJECTIVES To identify factors related to aetiology, prevention and treatment of non-traumatic posterior urethral stenosis and contractures. ACQUISITION OF EVIDENCE Review of the published evidence related to posterior urethral stenosis and contractures after PCa treatment, BPH therapies and orthotopic neobladder formation. PubMed database search with English and Spanish papers considered. Cohort studies, case series, prospective and retrospective studies and review papers were included. SYNTHESIS OF EVIDENCE Posterior urethral stenoses and contractures are common, leading to significant morbidity. A worsening on voiding quality should rise some concerns. Careful surgical and/or radiotherapic techniques prevent their development. Endoscopic therapies are the initial approach, with complex urethroplasties often required. Subsequent urinary incontinence, the most important sequelae, may need artificial sphincters. CONCLUSIONS Non-traumatic posterior urethral stenoses could be important complications, potentially compromising the outcomes of initial therapy. They could require complex surgeries leading to urinary incontinence.

Abstract
Urethral stricture after radiation therapy for localized prostate cancer is a delicate problem as the decreased availability of tissue healing and the close relation to the sphincter complicates any surgical approach. We here review the pathophysiology, dosimetry, and the disease specific aspects of urethral strictures after radiotherapy. Moreover we discuss different treatment option such as direct vision internal urethrotomy as well as techniques for open reconstruction with and without tissue transfer.

Improving Outcomes of Bulbomembranous Urethroplasty for Radiation-induced Urethral Strictures in Post-Urolume Era. Urology 2016; 99:240-245. [PMID: 27496299 DOI: 10.1016/j.urology.2016.07.031] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/08/2016] [Revised: 07/25/2016] [Accepted: 07/26/2016] [Indexed: 10/21/2022]
Abstract
OBJECTIVE To evaluate contemporary outcomes of excision and primary anastomosis (EPA) for the treatment of radiation-induced urethral strictures (RUS). PATIENTS AND METHODS A retrospective review of 72 patients undergoing EPA for RUS from 2007 to 2015 by a single surgeon was performed. We analyzed overall and long-term success rates of EPA urethroplasty and compared patient cohorts from two groups, 2007-2012 vs 2013-2015 (post-Urolume). RESULTS During the course of the study, we noted a near doubling of patient volume from the earlier (6.2 patients/year) to later (11.7 patients/year) cohorts. Among the 37 men treated from 2007 to 2012, we identified an EPA success rate of 70% compared with the improved 86% success rate in the subsequent cohort of 35 men treated from 2013 to 2015 (P = .07). Single dilation was successful in 50% of initial and 40% of subsequent cohort patients in the treatment of recurrence. Initial and subsequent cohorts varied only in regard to stricture length (mean 2.0 cm vs 3.0 cm in initial and subsequent cohorts, P = .001) and number treated with Urolume stent (initial 5 vs none in the later cohort, P = .03). Length of follow-up (median 50 [17-97] months for the initial and 22 [6-34] months for the later cohort) was not associated with recurrence. CONCLUSION Increasing numbers of RUS patients are presenting for urethral reconstruction in the post-Urolume era. With increasing experience, we improved success rates of EPA urethroplasty to over 85% despite increased stricture length.

Treatment of Urethral Strictures from Irradiation and Other Nonsurgical Forms of Pelvic Cancer Treatment. Adv Urol 2015; 2015:476390. [PMID: 26494994 PMCID: PMC4606407 DOI: 10.1155/2015/476390] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2015] [Accepted: 09/13/2015] [Indexed: 12/12/2022] Open
Abstract
Radiation therapy (RT), external beam radiation therapy (EBRT), brachytherapy (BT), photon beam therapy (PBT), high intensity focused ultrasound (HIFU), and cryotherapy are noninvasive treatment options for pelvic malignancies and prostate cancer. Though effective in treating cancer, urethral stricture disease is an underrecognized and poorly reported sequela of these treatment modalities. Studies estimate the incidence of stricture from BT to be 1.8%, EBRT 1.7%, combined EBRT and BT 5.2%, and cryotherapy 2.5%. Radiation effects on the genitourinary system can manifest early or months to years after treatment with the onus being on the clinician to investigate and rule-out stricture disease as an underlying etiology for lower urinary tract symptoms. Obliterative endarteritis resulting in ischemia and fibrosis of the irradiated tissue complicates treatment strategies, which include urethral dilation, direct-vision internal urethrotomy (DVIU), urethral stents, and urethroplasty. Failure rates for dilation and DVIU are exceedingly high with several studies indicating that urethroplasty is the most definitive and durable treatment modality for patients with radiation-induced stricture disease. However, a detailed discussion should be offered regarding development or worsening of incontinence after treatment with urethroplasty. Further studies are required to assess the nature and treatment of cryotherapy and HIFU-induced strictures.
