Port Site Recurrence (PSR) following laparoscopic tumor resections has been reported for a variety of tumors. Though PSR is a rare phenomenon, they most commonly occur following nephroureterectomies for upper tract urothelial carcinoma. Herein we report a novel case of a PSR following a robotic assisted nephroureterectomy for the sarcomatoid variant of urothelial carcinoma of the upper urinary tract.

INTRODUCTION: To improve care for patients after radical cystoprostatectomy (RCP), focus on survivorship issues such as sexual function needs to increase. Previous studies have demonstrated the burden of erectile dysfunction (ED) after RCP to be as high as 89%. AIM: To determine the rates of ED treatment use (phosphodiesterase type 5 inhibitors, injectable therapies, urethral suppositories, vacuum erection devices, and penile prosthetics) in patients with bladder cancer before and after RCP to better understand current patterns of care...

PURPOSE: Reconstruction of complex functional structures is increasingly being performed with vascularized composite allotransplantation. Penile transplantation is a novel vascularized composite allotransplantation treatment option for severe penile tissue loss and disfigurement. Three allogeneic human penile transplantations have been reported. We review these cases as well as penile transplant indications, preclinical models and immunosuppression therapy. MATERIALS AND METHODS: We performed a comprehensive literature review for the years 1970 to 2016 via MEDLINE®, PubMed® and Google with the key words "penis transplantation," "penile rejection," "penile replantation," "penile tissue loss" and "penis vascularized composite allotransplantation...

INTRODUCTION: Intracavernosal injection (ICI) therapy is widely used for the treatment of erectile dysfunction (ED). Its use in practice is largely empirical and has not been validated with evidence-based approaches. AIM: To compare two strategies for ICI, specifically a risk-based approach and an empiric-based approach, and assess the efficacy, patient satisfaction, and complication rates of the two treatment approaches. METHODS: After obtaining approval from the institutional review board, a prospective database of patients enrolled in the ICI program at the Johns Hopkins Hospital (Baltimore, MD, USA) from May 2012 through May 2014 was amassed...

INTRODUCTION: Neurogenic erectile dysfunction is a common sequela of radical prostatectomy. The etiology involves injury to the autonomic cavernous nerves, which arise from the major pelvic ganglion (MPG), and subsequent neuroinflammation, which leads to recruitment of macrophages to the injury site. Currently, two macrophage phenotypes are known: neurotoxic M1 macrophages and neuroprotective M2 macrophages. AIM: To examine whether bilateral cavernous nerve injury (BCNI) in a rat model of erectile dysfunction would increase recruitment of neurotoxic M1 macrophages to the MPG...

A versatile process to develop designer collagen scaffolds for hollow and tubular tissue engineering applications is presented. This process creates seamless and biomechanically tunable scaffolds ranging from ureter-like microsized tubings to structures with highly customized lumens that resemble intestinal villi, fluid bladders, and alveolar sacs that together with stem cells can potentially be used in preclinical and clinical settings.

Penile transplantation is an emerging option for patients with severe genital defects not amenable to traditional reconstructive options. In this article, we discuss the burgeoning problem of severe male genitourinary trauma in the military, the limitations of traditional reconstructive options in addressing these problems, and the potential for penile transplantation to provide improved outcomes. We also review the preclinical research and limited worldwide experience with penile transplantation to date, including lessons learned, and discuss the many important technical, logistical, and ethical considerations pertaining to penile transplantation that must be addressed to maximize the likelihood of successful implementation...

Circulating tumour cells (CTCs) have been studied as biomarkers of a number of solid malignancies. Potential clinical applications for CTC analysis include early cancer detection, disease staging, monitoring for recurrence, prognostication, and to aid in the selection of therapy. In the field of urologic oncology, CTCs have been most widely studied as prognostic biomarkers of castration-resistant prostate cancer. Additionally, emerging data support a role for CTCs to help identify which patients are most likely to respond to novel androgen-pathway targeted therapies, such as abiraterone and enzalutamide...

Penile squamous cell carcinoma (SCC) is primarily treated by surgical resection. Locally advanced and metastatic diseases require a multidisciplinary treatment approach. However, mortality and morbidity remain high, and novel molecular and immunotherapeutic targets are actively being sought. We investigated the expression of immune-checkpoint markers in penile cancers. Fifty-three invasive penile SCCs diagnosed between 1985 and 2013 were retrieved from our surgical pathology archives. Representative formalin-fixed, paraffin-embedded archival blocks were used for the construction of 2 high-density tissue microarrays...
