Breakage and detachment of the rigid cystoscope's distal tip: an unusual case of urological instrument malfunction.

Herein, we describe an unusual case of cystoscope damage during a planned laser cystolithotripsy in a 65-year-old male with a previous history of radical prostatectomy for prostate cancer and subsequent serial urethral dilations for bladder neck contracture. Upon crossing the penile urethra without exerting significant pressure, we noticed the cystoscope's distal metallic tip detachment. Therefore, we re-introduced another 22Fr cystoscope and removed the broken part with alligator forceps.

Case Presentation: Herein, we report a case of Jackstone vesical calculus in a 75-year-old male undergoing elective open prostate surgery for benign prostate hyperplasia refractory to medical treatment.

En bloc resection of bladder tumors: challenges and unmet needs in 2022.

Non-muscle invasive bladder cancer accounts for the majority of new bladder cancer diagnoses, and endoscopic transurethral resection of bladder tumor (TURBT) represents the standard-of-care. Although a relatively safe and common procedure, TURBT is often hampered by the questionable quality of resection. The evolution of surgical techniques has brought en bloc resection of bladder tumor (ERBT) to the forefront.

En bloc resection, is this the future of non-muscle invasive bladder cancer management? Presentation of our technique and brief review of the literature.

Introduction: The quality of the initial transurethral resection of bladder tumors (TURBT) plays a key role in accurate local staging thus affecting treatment decision-making and disease prognosis. TURBT is still the gold standard for non-muscle invasive bladder cancer (NMIBC). However, en bloc resection of bladder tumors (ERBT) gradually expanded as a promising alternative to TURBT, aiming to overcome certain inherent limitations of conventional resection.

Amyloidosis of the Urinary Bladder: A Systematic Review and a Proposed Management Algorithm.

Hypoxia-Inducible Factor 2a Expression Is Positively Correlated With Gleason Score in Prostate Cancer.

Background: One of the main factors in response to hypoxia in the tumor microenvironment is the hypoxia-inducible factor (HIF) pathway. Although its role in other solid tumors, particularly renal cell carcinoma, has been sufficiently elucidated, it remains elusive in prostate cancer. The aim of the present study was to investigate the expression of main proteins involved in this pathway and determine the correlation of the results with clinicopathological outcomes of patients with prostate cancer.

Endocrine consequences of treatment with the new androgen receptor axis-targeted agents for advanced prostate cancer.

Purpose: Prostate cancer (PCa) is the commonest non-cutaneous malignancy worldwide and the second cause of cancer death among males in the USA. Approval of the new androgen receptor axis-targeted (ARAT) agents (abiraterone acetate, enzalutamide, apalutamide, and darolutamide) has altered the course of advanced PCa. We aimed to assess the endocrine and metabolic adverse events associated with treatment using ARAT compounds.

Decreased prolyl hydroxylase 3 mRNA expression in oncocytomas compared with clear cell renal cell carcinoma.

Introduction: Hypoxia inducible factors (HIF) and prolyl hydroxylase domain (PHD) enzymes play a central role in tumor progression in clear cell renal cell carcinoma (ccRCC). However, there are currently no data regarding the behavior of this pathway (HIF/PHD) in a large number of benign renal tumors, the oncocytomas. The aim of the present study was to compare the expression levels of these factors between ccRCC and oncocytoma tumors.

mRNA overexpression of prolyl hydroxylase PHD3 is inversely related to nuclear grade in renal cell carcinoma.

The aim of the present study was to evaluate the relative mRNA expression levels of genes involved in the hypoxia inducible factor (HIF) signalling pathway in renal cell carcinoma (RCC) and to analyse their associations with clinicopathological parameters and survival outcomes. Reverse transcription-quantitative PCR was used to quantify the mRNA expression levels of HIF-1α, HIF-2α, prolyl hydroxylase (PHD)1, PHD2 and PHD3 in formalin-fixed paraffin-embedded (FFPE) tumour tissue samples from 41 patients with RCC, including 33 cases of clear cell RCC (ccRCC). FFPE samples of corresponding adjacent normal kidney tissues were used as a comparison.

HER-2 overexpression is a negative predictive factor for recurrence in patients with non-muscle-invasive bladder cancer on intravesical therapy.

Objective: HER-2 is overexpressed in a variety of human malignant tumors and has been widely used in the prognosis and treatment of breast cancer. In urothelial cell carcinoma of the bladder, some reports have shown an association between HER-2 overexpression and worse outcomes. The aim of this study was to examine the association between HER-2 expression and other clinicopathologic parameters in 48 patients treated for primary non-muscle-invasive transitional cell carcinoma of the bladder.

However, is stem cell therapy a viable treatment option for erectile dysfunction? The current body of literature provides a wide array of clinical trials performed on animal models simulating different types of human erectile dysfunction.

Sexual Dysfunction Among Young Men: Overview of Dietary Components Associated With Erectile Dysfunction.

Background: Sexual dysfunction is relatively common in young men, presenting in diverse manifestations, including erectile dysfunction (ED), for which dietary modifications, including increased intake of dietary antioxidants, have been suggested as promising and cost-efficient approaches.

Aim: To assess the consumption of selected dietary antioxidants, in particular flavonoids, in relation to ED symptoms in young men.

Methods: Men 18 to 40 years old were invited to complete an anonymous web-based questionnaire for this case-control study.

Should we expand the indications for varicocele treatment?

Current guidelines suggest that treatment of varicocele should be considered in patients with clinically palpable disease and abnormal semen parameters. However, the clinicians are often challenged with the decision whether to treat varicocele in patients with testicular pain or low testosterone levels. Moreover, varicocele is highly associated with DNA fragmentation due to the oxidative stress and it has been demonstrated that surgical repair of varicocele ameliorates oxidative stress markers and consequently the sperm DNA integrity.

Comparison Between Ambulatory and Conventional Urodynamics of the Modified Orthotopic Hautmann Neobladder.

Purpose: The aim of the present study was to determine the diagnostic accuracy of conventional and ambulatory urodynamic studies (UDS) in estimating neobladder function.

Methods: We evaluated 32 patients who underwent radical cystectomy and orthotopic Hautmann W neobladder with Abol-Enein-Ghoneim uretero-intestinal anastomosis for bladder cancer. The patients were initially examined by using both conventional and ambulatory UDS.

Impact of cancer and cancer treatment on male fertility.

While cancer, and especially testicular cancer and Hodgkin's disease, affects male fertility in many ways, the current increase of survival of male cancer patients of reproductive age or earlier has emerged as a new challenge to their subsequent ability to father children. Cancer treatments, including surgery, radiotherapy and chemotherapy, can have a transitory as well as a permanent detrimental impact on male fertility. Gonadotoxic effects and the length of time for sperm recovery after radiotherapy depends not only on initial semen quality, but also on gonadal dosage and the delivery method after chemotherapy, on the type of regimens and dosages and on the spermatogenesis phase that each drug impacts.
