Purpose: This study aimed to examine current global practices in regenerative therapy (RT) for erectile dysfunction (ED) and to establish expert recommendations for its use, addressing the current lack of solid evidence and standardized guidelines. Materials and Methods: A 39-question survey was developed by senior Global Andrology Forum (GAF) experts to comprehensively cover clinical aspects of RT. This was distributed globally via a secure online Google Form to ED specialists through the GAF website, international professional societies, and social media, the responses were analyzed and presented for frequencies as percentages. Consensus on expert recommendations for RT use was achieved using the Delphi method. Results: Out of 479 respondents from 62 countries, a third reported using RT for ED. The most popular treatment was low-intensity shock wave therapy (54.6%), followed by platelet-rich plasma (24.5%) and their combination (14.7%), with stem cell therapy being the least used (3.7%). The primary indication for RT was the refractory or adverse effects of PDE5 inhibitors, with the best effectiveness reported in middle-aged and mild-to-moderate ED patients. Respondents were confident about its overall safety, with a significant number expressing interest in RT’s future use, despite pending guidelines support. Conclusions This inaugural global survey reveals a growing use of RT in ED treatment, showcasing its diverse clinical applications and potential for future widespread adoption. However, the lack of comprehensive evidence and clear guidelines requires further research to standardize RT practices in ED treatment.

BACKGROUND: The urinary tract can be affected by both congenital abnormalities as well as acquired disorders, such ascancer, trauma, infection, inflammation, and iatrogenic injuries, all of which may lead to organ damage requiring eventualreconstruction. As a gold standard, gastrointestinal segment is used for urinary bladder reconstruction. However, one majorproblem is that while bladder tissue prevents reabsorption of specific solutes, gastrointestinal tissue actually absorbs them.Therefore, tissue engineering approach had been attempted to provide an alternative tissue graft for urinary bladderreconstruction. METHODS: Human adipose-derived stem cells isolated from fat tissues were differentiated into smooth muscle cells andthen seeded onto a triple-layered PLGA sheet to form a bladder construct. Adult athymic rats underwent subtotal urinarybladder resection and were divided into three treatment groups (n = 3): Group 1 (‘‘sham’’) underwent anastomosis of theremaining basal region, Group 2 underwent reconstruction with the cell-free scaffold, and Group 3 underwent reconstructionwith the tissue-engineered bladder construct. Animals were monitored on a daily basis and euthanisation wasperformed whenever a decline in animal health was detected. RESULTS: All animals in Groups 1, 2 and 3 survived for at least 7 days and were followed up to a maximum of 12 weekspost-operation. It was found that by Day 14, substantial ingrowth of smooth muscle and urothelial cells had occurred inGroup 2 and 3. In the long-term follow up of group 3 (tissue-engineered bladder construct group), it was found that theurinary bladder wall was completely regenerated and bladder function was fully restored. Urodynamic and radiologicalevaluations of the reconstructed bladder showed a return to normal bladder volume and function.Histological analysisrevealed the presence of three muscular layers and a urothelium similar to that of a normal bladder. Immunohistochemicalstaining using human-specific myocyte markers (myosin heavy chain and smoothelin) confirmed the incorporation of theseeded cells in the newly regenerated muscular layers. CONCLUSION Implantation of PLGA construct seeded with smooth muscle cells derived from human adipose stemcells can lead to regeneration of the muscular layers and urothelial ingrowth, leading to formation of a completelyfunctional urinary bladder.

BACKGROUND: Urinary tract is subjected to a variety of disorders such as urethral stricture, which often develops as a result of scarring process. Urethral stricture can be treated by urethral dilation and urethrotomy; but in cases of long urethral strictures, substitution urethroplasty with genital skin and buccal mucosa grafts is the only option. However a number of complications such as infection as a result of hair growth in neo-urethra, and stone formation restrict the application of those grafts. Therefore, tissue engineering techniques recently emerged as an alternative approach, aiming to overcome those restrictions. The aim of this review is to provide a comprehensive coverage on the strategies employed and the translational status of urethral tissue engineering over the past years and to propose a combinatory strategy for the future of urethral tissue engineering. METHODS: Data collection was based on the key articles published in English language in years between 2006 and 2018 using the searching terms of urethral stricture and tissue engineering on PubMed database. RESULTS: Differentiation of mesenchymal stem cells into urothelial and smooth muscle cells to be used for urologic application does not offer any advantage over autologous urothelial and smooth muscle cells. Among studied scaffolds, synthetic scaffolds with proper porosity and mechanical strength is the best option to be used for urethral tissue engineering. CONCLUSION: Hypoxia-preconditioned mesenchymal stem cells in combination with autologous cells seeded on a prevascularized synthetic and biodegradable scaffold can be said to be the best combinatory strategy in engineering of human urethra.

PURPOSE: Urinary calculi is a familiar disease. A well-known complication of endourological treatment for impacted ureteral stones is the formation of ureteral strictures, which has been reported to occur in 14.2% to 24% of cases. MATERIALS AND METHODS: This was a prospective study. Ureterotripsy treatment was used on patients with impacted ureteral stones. Then, after 3 months and 6 months, the condition of these patients was assessed by means of a kidney-ureter-bladder (KUB) ultrasound. If the KUB ultrasound indicated moderate to serious hydronephrosis, the patient was further assessed by means of a computed tomography intravenous urogram or retrograde pyelogram to confirm the occurrence of ureteral strictures. RESULTS: Of the 77 patients who participated in the study, 5 developed ureteral strictures. Thus, the stricture rate was 7.8%. An analysis of the intraoperative risk factors including perforation of the ureter, damage to the mucous membrane, and residual stone impacted within the ureter mucosa revealed that none of these factors contributed significantly to the formation of the ureteric strictures. The stone-related risk factors that were taken into consideration were stone size, stone impaction site, and duration of impaction. These stone factors also did not contribute significantly to the formation of the ureteral strictures. CONCLUSIONS: This prospective study failed to identify any predictable factors for ureteral stricture formation. It is proposed that all patients undergo a simple postoperative KUB ultrasound screening 3 months after undergoing endoscopic treatment for impacted ureteral stones.

The Aging Male Symptoms Scale (AMS) measures health-related quality of life in aging men. The objective of this paper is to describe the translation and validation of the AMS into Bahasa Melayu (BM). The original English version of the AMS was translated into BM by 2 translators to produce BM1 and BM2, and subsequently harmonized to produce BM3. Two other independent translators, blinded to the English version, back-translated BM3 to yield E2 and E3. All versions (BM1, BM2, BM3, E2, E3) were compared with the English version. The BM pre-final version was produced, and pre-tested in 8 participants. Proportion Agreement, Weighted Kappa, Spearman Rank Correlation Coefficient, and verbatim responses were used. The English and the BM versions showed excellent equivalence (weighted Kappa and Spearman Rank Coefficients, ranged from 0.72 to 1.00, and Proportion Agreement values ranged from 75.0% to 100%). In conclusion, the BM version of the AMS was successfully translated and adapted.
