Introduction We investigated the prostatic urethral lift, a novel, minimally invasive treatment for symptomatic lower urinary tract complaints presumed to be from benign prostatic hyperplasia (BPH), which aims to mechanically open the prostatic urethra without ablation or resection. We hypothesized that this novel approach would not degrade erectile or ejaculatory function. Aims We sought to determine the effect of the prostatic urethral lift procedure on erectile and ejaculatory function. Methods The procedure was performed on 64 men in Australia with an average age of 66.9 years and an average duration of lower urinary tract symptom (LUTS) of 4.7 years. Primary inclusion criteria included International Prostate Symptom Score (IPSS) > 13, Qmax of 5–12 mL/second, and prostate specific antigen (PSA) < 10 ng/mL. Baseline IPSS was 22.9 ± 5.4 (N = 64). There were no inclusion criteria for sexual function. Baseline Sexual Health Inventory for Men (SHIM) was 11.7 ± 8.6 (N = 58); baseline Male Sexual Health Questionnaire for Ejaculatory Dysfunction (MSHQ-EjD) function score was 9.0 ± 3.7 (N = 46); and lack of sexual activity or unwillingness to answer sexual function questionnaires accounted for the reduced sample size in the sexual function instruments. Implants were placed to separate encroaching lateral prostatic lobes. Main Outcome Measures Patients were evaluated at 6 weeks and 3, 6, and 12 months postprocedure via the SHIM and MSHQ-EjD instruments. Results There was no evidence of degradation in sexual function after treatment for LUTS with the prostatic urethral lift procedure. Erectile function, as measured by SHIM, was slightly increased at all time points as compared with baseline. No patient reported retrograde ejaculation at any follow-up visit. Conclusions We demonstrated significant improvement in LUTS with no evidence of degradation in erectile or ejaculatory function after treatment with the prostatic urethral lift procedure. This procedure warrants further study as a new option for patients underserved by current treatments for LUTS/BPH.

Introduction More than half of intraoperative complications occur during dilatation of the corpora cavernosa, a critical step in the placement of any type of penile prosthesis, which can be especially difficult in a patient with corporal fibrosis. A late manifestation of cylinder placement can be impending erosion with lateral extrusion or medial deviation (into the urethra) of the distal tips. There are many different approaches to try and fix these surgical issues. Aim The review article evaluates the many different surgical techniques prosthetic surgeons use in the management of intraoperative complications and lateral extrusion. Methods A review of the literature was preformed with published results being evaluated to try to help guide the management of intraoperative complications and impending distal erosion. There is a special focus on dilation of the corpora cavernosa. Main Outcomes Measures The article reviews and evaluates the outcomes of the landmark papers in the management of intraoperative complications and impending distal erosion. Results Intraoperative complications of penile implant placement can be distressing for the prosthetic surgeon, but with proper recognition, most of these complications can be navigated with excellent postoperative results. Conclusions This review article summarizes many of the techniques, outcomes, and new developments in the complicated field of penile prosthetic surgery to help guide the implanting surgeon.

High-grade urothelial cell carcinoma of the bladder has a poor prognosis when lymph nodes are involved. Despite curative therapy for clinically-localized disease, over half of the muscle-invasive urothelial cell carcinoma patients will develop metastases and die within 5 years. There are currently no described xenograft models that consistently mimic urothelial cell carcinoma metastasis. To develop a patient-derived orthotopic xenograft model to mimic clinical urothelial cell carcinoma progression to metastatic disease, the urothelial cell carcinoma cell line UM-UC-3 and two urothelial cell carcinoma patient specimens were doubly tagged with Luciferase/RFP and were intra-vesically (IB) instilled into NOD/SCID mice with or without lymph node stromal cells (HK cells). Mice were monitored weekly with bioluminescence imaging to assess tumor growth and metastasis. Primary tumors and organs were harvested for bioluminescence imaging, weight, and formalin-fixed for hematoxylin and eosin and immunohistochemistry staining. In this patient-derived orthotopic xenograft model, xenograft tumors showed better implantation rates than currently reported using other models. Xenograft tumors histologically resembled pre-implanted primary specimens from patients, presenting muscle-invasive growth patterns. In the presence of HK cells, tumor formation, tumor angiogenesis, and distant organ metastasis were significantly enhanced in both UM-UC-3 cells and patient-derived specimens. Thus, we established a unique, reproducible patient-derived orthotopic xenograft model using human high-grade urothelial cell carcinoma cells and lymph node stromal cells. It allows for investigating the mechanism involved in tumor formation and metastasis, and therefore it is useful for future testing the optimal sequence of conventional drugs or the efficacy of novel therapeutic drugs.

There is an established link between lower urinary tract symptoms (LUTS) caused by benign prostatic hyperplasia (BPH) and erectile dysfunction (ED). The medical and surgical management of LUTS can affect erectile function (EF), cause ejaculatory dysfunction (EjD) or affect libido. This article will review the effects of these therapies on sexual function.

Erectile dysfunction has been a concern for men since the beginning of written history. For many men it can lead to severe psychological distress and humiliation. The treatment of erectile dysfunction has advanced significantly over the past 200 years. Men today are presented with many more viable therapy options leading to improved efficacy and more satisfactory sex lives. The objective of this article is to explore historical options for the treatment of erectile dysfunction, with particular emphasis on the development and progression of the inflatable penile prosthesis.
