Molecular biomarkers in the context of focal therapy for prostate cancer: Recommendations of a delphi consensus from the focal therapy society

BACKGROUND: Focal therapy (FT) for prostate cancer (PCa) is promising. However, long-term oncological results are awaited and there is no consensus on follow-up strategies. Molecular biomarkers (MB) may be useful in selecting, treating and following up men undergoing FT, though there is limited evidence in this field to guide practice. We aimed to conduct a consensus meeting, endorsed by the Focal Therapy Society, amongst a large group of experts, to understand the potential utility of MB in FT for localized PCa. METHODS: A 38-item questionnaire was built following a literature search. The authors then performed three rounds of a Delphi Consensus using DelphiManager, using the GRADE grid scoring system, followed by a face-to-face expert meeting. Three areas of interest were identified and covered concerning MB for FT, 1) the current/present role; 2) the potential/future role; 3) the recommended features for future studies. Consensus was defined using a 70% agreement threshold. RESULTS: Of 95 invited experts, 42 (44.2%) completed the three Delphi rounds. Twenty-four items reached a consensus and they were then approved at the meeting involving (N.=15) experts. Fourteen items reached a consensus on uncertainty, or they did not reach a consensus. They were re-discussed, resulting in a consensus (N.=3), a consensus on a partial agreement (N.=1), and a consensus on uncertainty (N.=10). A final list of statements were derived from the approved and discussed items, with the addition of three generated statements, to provide guidance regarding MB in the context of FT for localized PCa. Research efforts in this field should be considered a priority. CONCLUSIONS: The present study detailed an initial consensus on the use of MB in FT for PCa. This is until evidence becomes available on the subject

Evaluation and treatment of erectile dysfunction in the aging male: a mini-review

Before the 20th century, individuals often did not live beyond the reproductive years, and sexuality of the elderly was not an issue. However, in the current era it is known that as life expectancy improves, both men and women are seeking to preserve their sexuality into old age. While the appreciation of sexuality persists with aging, a decline in sexual activity is typically seen with, and can be attributed to both general health problems as well as specific sexual dysfunctions. Erectile dysfunction is the most frequently diagnosed sexual dysfunction in the older male population. This mini-review provides an overview of contemporary literature concerning epidemiology, pathophysiology, assessment and treatment of erectile dysfunction in the aging male.status: publishe

Tissue Engineering of Urinary Bladder and Urethra: Advances from Bench to Patients

Urinary tract is subjected to many varieties of pathologies since birth including congenital anomalies, trauma, inflammatory lesions, and malignancy. These diseases necessitate the replacement of involved organs and tissues. Shortage of organ donation, problems of immunosuppression, and complications associated with the use of nonnative tissues have urged clinicians and scientists to investigate new therapies, namely, tissue engineering. Tissue engineering follows principles of cell transplantation, materials science, and engineering. Epithelial and muscle cells can be harvested and used for reconstruction of the engineered grafts. These cells must be delivered in a well-organized and differentiated condition because water-seal epithelium and well-oriented muscle layer are needed for proper function of the substitute tissues. Synthetic or natural scaffolds have been used for engineering lower urinary tract. Harnessing autologous cells to produce their own matrix and form scaffolds is a new strategy for engineering bladder and urethra. This self-assembly technique avoids the biosafety and immunological reactions related to the use of biodegradable scaffolds. Autologous equivalents have already been produced for pigs (bladder) and human (urethra and bladder). The purpose of this paper is to present a review for the existing methods of engineering bladder and urethra and to point toward perspectives for their replacement

A novel method in decision making for the diagnosis of anterior urethral stricture: using methylene blue dye

ObjectiveThe use of methylene blue dye (MB) to highlight anatomical structures in urology has been well-established. Urethral stricture may extend about a centimeter beyond the abnormal area seen on urethrogram. Although the current literature suggests a tension-free and end- to- end anastomosis after excision of the strictured urethral segment with spongiofibrosis and surrounding corpus spongiosum in short bulbar strictures, some centers dealing with urethroplasty prefer anastomosis for short bulbar strictures while others prefer augmentation. With this study, use of MB for delineating stricture line and assessing spongiofibrosis in the diagnosis of urethral stricture was evaluated.Material and methodsFive cc MB including 10 mg/mL is diluted with 10 cc saline. In the first scenario, MB is gently injected into urethra via the meatus before the urethroplasty procedure. Meanwhile, the extent of urethral segment stained by MB is noted. In the second scenario (MB spongiosography) in short bulbar stricture, insulin needles are inserted in spongiosa of the stricture site distally and proximally. MB is gently injected with distal needle. The two remaining needles are then observed. Presence of MB efflux in proximal needle implies deficiency of significant spongiofibrosis, so buccal augmentation is performed. Absence of efflux of MB implies significant spongiofibrosis and anastomotik site excised.ResultsFour hundred and ninety-two consecutive cases prospectively evaluated between 2010 and 2014. Precise staining of stricture was successfully observed in 464 (94%) patients. Grossly normal appearing urothelium remained pink. Histopathology confirmed that the stained urethra had a stricture. Of the 22 short bulbar idiopathic strictures, in 18 (82%) MB was seen across the stricture and urethral transection was avoided. Anastomosis was performed in 4 (18%) cases where no MB went across the primary excision. There were no known allergic complications.ConclusionMB aids in delineating the urethral lumen and exact site of stricture that needs augmentation. MB Spongiography in short bulbar strictures could be used as a beneficial guide in relation to the type of urethral repair to be performed in terms of augmentation versus excision and anastomosis

Management of complex and redo cases of pelvic fracture urethral injuries

Objectives: Pelvic fracture urethral injuries (PFUI) result from traumatic disruption of the urethra. A significant proportion of cases are complex rendering their management challenging. We described management strategies for eight different complex PFUI scenarios. Methods: Our centre is a tertiary referral centre for complex PFUI cases. We maintain a prospective database (1995–2016), which we retrospectively analysed. All patients with PFUI managed at our institute were included. Results: Over two decades 1062 cases of PFUI were managed at our institute (521 primary and 541 redo cases). Most redo cases were referred to us from other centres. Redo cases had up to five prior attempts at urethroplasty. We managed complex cases, which included bulbar ischemia, young boys and girls with PFUI, PFUI with double block, concomitant PFUI and iatrogenic anterior urethral strictures. Bulbar ischemia merits substitution urethroplasty, most commonly, using pedicled preputial tube. PFUI in young girls is usually associated with urethrovaginal fistula. Young boys with PFUI commonly have a long gap necessitating trans-abdominal approach. Our success rate with individualised management is 85.60% in primary cases, 79.13% in redo cases and 82.40% in cases of bulbar ischemia. Conclusion: The definition of complex PFUI is ever expanding. The best chance of success is at the first attempt. Anastomotic urethroplasty for PFUI should be performed in experienced hands at high volume centres.

Evaluation of Bi-Layer Silk Fibroin Grafts for Tubular Ureteroplasty in a Porcine Defect Model.

Ureteral reconstruction with autologous tissue grafts is often limited by tissue availability and donor site morbidity. This study investigates the performance of acellular, bi-layer silk fibroin (BLSF) scaffolds in a porcine model of ureteroplasty. Tubular ureteroplasty with BLSF grafts in combination with transient stenting for 8 weeks was performed in adult female, Yucatan, mini-swine (N = 5). Animals were maintained for 12 weeks post-op with imaging of neoconduits using ultrasonography and retrograde ureteropyelography carried out at 2 and 4 weeks intervals. End-point analyses of ureteral neotissues and unoperated controls included histological, immunohistochemical (IHC), histomorphometric evaluations as well as ex vivo functional assessments of contraction/relaxation. All animals survived until scheduled euthanasia and displayed mild hydronephrosis (Grades 1-2) in reconstructed collecting systems during the 8 weeks stenting period with one animal presenting with a persistent subcutaneous fistula at 2 weeks post-op. By 12 weeks of scaffold implantation, unstented neoconduits led to severe hydronephrosis (Grade 4) and stricture formation in the interior of graft sites in 80% of swine. Bulk scaffold extrusion into the distal ureter was also apparent in 60% of swine contributing to ureteral obstruction. However, histological and IHC analyses revealed the formation of innervated, vascularized neotissues with a-smooth muscle actin+ and SM22α+ smooth muscle bundles as well as uroplakin 3A+ and pan-cytokeratin + urothelium. Ex vivo contractility and relaxation responses of neotissues were similar to unoperated control segments. BLSF biomaterials represent emerging platforms for tubular ureteroplasty, however further optimization is needed to improve in vivo degradation kinetics and mitigate stricture formation

Evaluation of Bi-Layer Silk Fibroin Grafts for Penile Tunica Albuginea Repair in a Rabbit Corporoplasty Model

The use of autologous tissue grafts for tunica albuginea repair in Peyronie's disease and congenital chordee is often restricted by limited tissue availability and donor site morbidity, therefore new biomaterial options are needed. In this study, bi-layer silk fibroin (BLSF) scaffolds were investigated to support functional tissue regeneration of tunica albuginea in a rabbit corporoplasty model. Eighteen adult male, New Zealand white rabbits were randomized to nonsurgical controls (NSC, N = 3), or subjected to corporoplasty with BLSF grafts (N = 5); decellularized small intestinal submucosa (SIS) matrices (N = 5); or autologous tunica vaginalis (TV) flaps (N = 5). End-point evaluations were cavernosography, cavernosometry, histological, immunohistochemical, and histomorphometric assessments. Maximum intracorporal pressures (ICP) following papaverine-induced erection were similar between all groups. Eighty percent of rabbits repaired with BLSF scaffolds or TV flaps achieved full rigid erections, compared to 40% of SIS reconstructed animals. Five-minute peak erections were maintained in 60% of BLSF rabbits, compared to 20% of SIS and TV flap reconstructed rabbits. Graft perforation occurred in 60% of TV group at maximum ICP compared to 20% of BLSF cohort. Neotissues supported by SIS and BLSF scaffolds were composed of collagen type I and elastin fibers similar to NSC. SIS and TV flaps showed significantly elevated levels of corporal fibrosis relative to NSC with a corresponding decrease in corporal smooth muscle cells expressing contractile proteins. BLSF biomaterials represent emerging platforms for corporoplasty and produce superior functional and histological outcomes in comparison to TV flaps and SIS matrices for tunica albuginea repair
