Despite its relative commonality, accounting for over 2% of urological visits, chronic scrotal content pain is complex to manage and patients may be required to access multiple providers and undergo invasive procedures, including microsurgical spermatic cord denervation (MSCD) surgery. Objective: The objective of this study was to understand the experiences and perspectives of persons with chronic scrotal content pain and accessing MSCD surgery. Design: An exploratory qualitative design, guided by interpretive description and integrated knowledge translation, was adopted. Methods: We conducted in-depth qualitative interviews with six patients with chronic scrotal content pain who underwent MSCD surgery in a surgical center in Western Canada. Data were analyzed thematically. Results: Analysis of the study data resulted in three core themes: living with chronic scrotal content pain, quality of life, and MSCD procedure and outcomes. We highlight the debilitating nature of pain and the broad impacts upon health, quality of life, and social functioning. Participants described how MSCD surgery offered an effective solution for persistent and debilitating pain. For the participants, MSCD surgery offered hope and the chance to regain their normality. Conclusion: For those with chronic scrotal content pain, access to a pain specialist, along with the adoption of a biopsychosocial approach to pain and early access to MSCD surgery, may improve patient experiences and outcomes. Considering the high prevalence of urological pain, greater interdisciplinary care is needed in order to support more effective and timely management.","PeriodicalId":23010,"journal":{"name":"Therapeutic Advances in Urology","volume":"15 ","pages":"17562872231196685"},"PeriodicalIF":2.0,"publicationDate":"2023-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/d5/34/10.1177_17562872231196685.PMC10521267.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41154003","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The approach to inserting an IPP in a neophallus is different and more challenging compared to that of an anatomical penis due to the absence of anatomical structures such as the corpora cavernosa, and the more tenuous blood supply of the neophallus and reconstructed urethra. In addition, the ideal surgical techniques and devices for use in the neophallus have not been defined. This review systematically summarises the literature on the insertion of IPP in the neophallus of individuals AFAB. In particular, the described techniques, types of devices used and peri-operative and patient-reported outcomes are emphasised. An initial search of the PubMed database was performed on 16 September 2022 and an updated search was performed on 26 May 2023. Overall, 185 articles were screened for eligibility and 15 studies fulfilled the inclusion criteria and were included in the analysis. Two studies reported outcomes on the zephyr surgical implant 475 FTM device and the others reported outcomes on the Boston Scientific AMS 600/700^TM CX 3-piece inflatable, AMS Ambicor^TM 2-piece inflatable, Coloplast Titan^® or Dynaflex devices. Overall, 1106 IPPs were analysed. The infection rate was 4.2%-50%, with most studies reporting an infection rate of <30%.

Platinum-based chemotherapy is most often used in the first-line treatment of mUC, and while response rates approach about 50%, disease control is usually short-lived upon completion of the standard three to six cycles of chemotherapy.

The treatment paradigm for prostate cancer has evolved with the emergence of a variety of novel therapies which have improved survival; however, treatment-related toxicities are abundant and durable responses remain rare. Immune checkpoint inhibitors have shown modest activity in a small subset of patients with prostate cancer and have not had an impact on most men with advanced disease. The discovery of prostate-specific membrane antigen (PSMA) and the understanding of its specificity to prostate cancer has identified it as an ideal tumor-associated antigen and has revived the enthusiasm for immunotherapeutics in prostate cancer. T-cell immunotherapy in the form of bispecific T-cell engagers (BiTEs) and chimeric antigen receptor (CAR) T-cell therapy have shown exceptional success in treating various hematologic malignancies, and are now being tested in patients with prostate cancer with drug design centered on various target ligands including not just PSMA, but others as well including six-transmembrane epithelial antigen of the prostate 1 (STEAP1) and prostate stem cell antigen (PSCA). This summative review will focus on the data surrounding PSMA-targeting T-cell therapies. Early clinical studies with both classes of T-cell redirecting therapies have demonstrated antitumor activity; however, there are multiple challenges with this class of agents, including dose-limiting toxicity, 'on-target, off-tumor' immune-related toxicity, and difficulty in maintaining sustained immune responses within a complex and overtly immunosuppressive tumor microenvironment. Reflecting on experiences from recent trials has been key toward understanding mechanisms of immune escape and limitations in developing these drugs in prostate cancer. Newer generation BiTE and CAR T-cell constructs, either alone or as part of combination therapy, are currently under investigation with modifications in drug design to overcome these barriers.
