PURPOSE OF REVIEW The clinical significance of ureteral and urethral recurrence in patients treated with radical cystectomy for bladder cancer is scarce and heterogeneous. The aim of the current review is to summarize the recent literature on incidence, diagnosis and oncologic outcomes of ureteral and urethral recurrences after radical cystectomy. RECENT FINDINGS Frozen section analysis (FSA) of ureteral margin had a sensitivity and specificity of 69-77 and 83-96%, respectively. Considering the ureteral margin, the reported sensitivity and specificity were 33-93 and 99-100%, respectively. Transurethral biopsy of the prostatic urethra might help in counseling patients' treatment, although its accuracy and prognostic role is highly questionable. In patients treated with radical cystectomy, recurrence of the urethra or ureteral are rare, occurring approximately in 5% of patients. During the follow-up, urinary cytology and cross-sectional imaging improve the early detection of recurrence in asymptomatic patients, although the majority are diagnosed for symptomatic presentation. Their use should be tailored to the patient's risk of ureteral and/or urethral recurrence. Urethrectomy is indicated in case of singular urethral recurrence, whereas no clear data exists regarding the best management of ureteral recurrence, except surgical removal. SUMMARY Intraoperative FSA of ureters and urethra share good specificity but poor sensitivity. Recurrence at urethra and upper tract are rare and discordant data exists regarding survival outcomes. Oncologic surveillance after radical cystectomy with the aim to detect these recurrences should be tailored to the individualized patient's risk.PURPOSE OF REVIEW Radical cystectomy is the definitive surgical treatment for aggressive bladder cancer. The robotic platform offers a new approach to radical cystectomy, but the benefits are unclear. This review examines the latest evidence, with a particular focus on developments in the last two years. RECENT FINDINGS Prospective evaluations of open (ORC) and robot-assisted radical cystectomy (RARC) are emerging. The radical cystectomy in patients with bladder cancer trial reported in 2018 and demonstrated oncological noninferiority for both approaches and marginal shorter length of stays with RARC using an extracorporeal reconstruction. The trial confirmed prospective randomized comparisons are possible, and replicates observations from two earlier, smaller randomised controlled trials with longer follow-up. Although there has been significant traction to the intracorporeal approach to RARC, randomized trial evidence is awaited to show any benefit over ORC. SUMMARY New evidence alludes to the noninferiority of the robotic platform in radical cystectomy in comparison to open surgery. There is minimal evidence of a clinically meaningful benefit. Until this is addressed, ORC remains the gold standard for the definitive surgical management of bladder cancer.PURPOSE OF REVIEW The standard diagnosis of carcinoma in situ (CIS) of the bladder, based on white light cystoscopy and urine cytology, is limited because CIS can vary from normal-appearing mucosa to a lesion indistinguishable from an inflammatory process. Intravesical instillation of Bacillus Calmette-Guerin (BCG) remains first-line therapy; however, a significant proportion of cases persist or recur after BCG treatment. This review summarizes recent improvements in the detection and treatment of CIS. RECENT FINDINGS The new optical technologies improve CIS detection, with a potential positive impact on oncological outcomes. The usefulness of MRI-photodynamic diagnosis fusion transurethral resection in CIS detection is unclear and further studies are needed. BCG instillation remains the first-line therapy in CIS patients and seems to improve recurrence and progression rates, especially with the use of maintenance. Intravesical device-assisted therapies could be effective in both BCG-naïve and BCG-unresponsive CIS patients, but further studies are ongoing to clarify their clinical benefit. A phase II clinical trial with pembrolizumab has shown the potential effectiveness of immune checkpoint inhibitors in BCG-unresponsive CIS patients and further trials are ongoing. SUMMARY New optical techniques increase the CIS detection rate. Erastin2 in vitro BCG instillation remains the first-line treatment. Immune checkpoint inhibitors could be a future alternative in BCG-naïve and BCG-unresponsive CIS patients.PURPOSE OF REVIEW Contrary to historic dogma, many tissues and organs in the human body contain a resident population of bacteria, fungi, and viruses collectively known as the microbiome. The microbiome plays a role in both homeostatic symbiosis and also pathogenic dysbiosis in a wide array of diseases. Our understanding of the relationship between the microbiome and male factor infertility is in its infancy but is slowly evolving. RECENT FINDINGS Recent literature indicates that semen (and likely the testis) is not sterile and contains a distinct microbiome, and these changes in its composition are associated with alterations in semen quality and fertility status. Preliminary investigation indicates that manipulating the human microbiome may have implications in improving semen parameters and fertility. SUMMARY In this review, we describe relationships between the microbiome and the genitourinary system, discuss the prior work on the relationship among bacteriospermia, leukocytospermia and male factor infertility, and summarize the current literature utilizing 16s rRNA-based next-generation sequencing on the seminal and testicular microbiome. We explore the specific microbial taxa implicated in various aspects of spermatic dysfunction and introduce preliminary evidence for therapeutic approaches to alter the microbiome and improve fertility status.PURPOSE OF REVIEW We aim to conduct a systematic review of the literature, document all reported cases of breast cancer development in cis men and female-to-male (FtM) transgender men undergoing testosterone replacement therapy (TRT), and determine if testosterone poses a substantial risk of breast cancer development and recurrence. RECENT FINDINGS A systematic search through December 2019 was performed. Out of 1890, 15 studies were eligible for inclusion in the final analyses. In total, 22 patients have developed breast cancer while on testosterone treatment. Four cases were cis men, whereas 18 cases were FtM. Age ranged from 18 to 61 years. Testosterone treatment duration ranged from 5 weeks up to 25 years. SUMMARY There is a relatively higher incidence of BCa in FtM on CSH therapy compared with cis men on TRT. Because of the small sample size of reported cases, we cannot delineate the exact relationship between testosterone therapy and BCa development. Additionally, we have limited data to suggest that TRT should or should not be contraindicated in cis men and FtM with a prior history of breast cancer.
