BACKGROUND: Radical cystectomy (RC) is the standard surgical treatment for patients with muscle-invasive bladder cancer, but the prognosis is not favorable, and new prognostic factors need to be discovered. We investigated the potential of depth of invasion (DOI) as a prognostic factor in patients with muscle-invasive bladder cancer who underwent RC. Furthermore, we examined the association between preoperative levels of circulating cell-free DNA and DOI. MATERIALS AND METHODS: We retrospectively reviewed patients who underwent RC between January 2007 and December 2017; those who received neoadjuvant chemotherapy were excluded...

BACKGROUND: The urinary retention is recognized as a promoting factor for bladder cancer, but its role as prognostic factor of therapeutic response has not yet been widely considered. To correlate bladder outlet characteristics with short-term response to treatment in non-muscle-invasive bladder cancer. MATERIALS AND METHODS: We carried out a case-control study on 600 consecutive patients with a first diagnosis of non-muscle-invasive bladder cancer, recruited at the first endoscopic follow-up visit after standard treatment: 200 patients were not tumor-free (cases) and 400 were tumor-free (controls)...

A 69-year-old man underwent 78 Gy/39 Fr of intensity-modulated radiation therapy for prostate cancer. Seven years after radiotherapy, a nonpapillary bladder tumor was identified. Transurethral resection of the bladder tumor was performed, and the pathological diagnosis was spindle cell sarcoma. Immunostaining revealed KIT- , DOG1++ , CD34- , Actin++ , Cytokeratin- , Desmin- , S100 protein- , and Vimentin++ . No tumor recurrence was observed until 17 months after tumor resection. DOG1 is strongly and specifically expressed in gastrointestinal stromal tumors...

OBJECTIVES: To test for differences in overall and recurrence-free survival between laparoscopic and open surgical approaches in patients undergoing radical nephroureterectomy (RNU) for upper tract urothelial carcinoma (UTUC). MATERIALS AND METHODS: We retrospectively identified patients treated for UTUC from 2010 to 2020 from our institutional database. Patients undergoing laparoscopic or open RNU with no suspicion of metastasis (cM0) were for the current study population...

BACKGROUND: Bladder cancer is a common and highly heterogeneous malignant tumor with a relatively poor prognosis. Thus, personalized treatment strategies for bladder cancer are essential for improving patient outcomes. MATERIALS AND METHODS: We developed an efficient 3-dimensional in vitro organoid culture system for bladder cancer organoids (BCOs), which maintains the homology with the original patient tumors and the heterogeneity between different individuals...

BACKGROUND: Plaque incision/excision and grafting are surgical techniques used to treat patients with Peyronie's disease who are refractory to less invasive interventions, have severe penile curvature, or have an hourglass deformity. However, the procedure carries the risk of penile sensory loss because of the need for dissection of the neurovascular bundle (NVB). The aim of this study was to assess the feasibility of a novel technique for unilateral NVB dissection and its ability to preserve penile sensitivity while maintaining adequate correction of the penile curvature...

BACKGROUND: To determine the impact of pre-transplant diabetes mellitus (DM) and post-transplant hypertension (HT) at 1 year on renal allograft survival in all adult first kidney-only (FKO) transplant recipients at a single transplant center in Johannesburg, South Africa. MATERIALS AND METHODS: A retrospective review was conducted of all adult FKO transplant procedures at the Charlotte Maxeke Johannesburg Academic Hospital transplant unit between 1966 and 2013. RESULTS: During the stipulated timeframe, 1685 adult FKO transplant procedures were performed...

BACKGROUND: Vesical Imaging-Reporting and Data System (VI-RADS) was developed as a structured reporting tool to anticipate the possibility of muscle invasion. This study is aimed to investigate the diagnostic accuracy of VI-RADS for discriminating T2 from T1 bladder cancer. MATERIALS AND METHODS: Scopus, Web of Science, PubMed, and Embase were searched on October 4, 2021, for studies with the following characteristics: (1) bladder cancer patient population, (2) VI-RADS as an index test, (3) retransurethral resection of bladder tumor/cystectomy as a reference, and (4) adequate VI-RADS score data for T1 and T2 lesions...

OBJECTIVES: We aimed to prospectively compare lower urinary tract symptoms in premenopausal and postmenopausal women with acute uncomplicated cystitis before and after antibiotic therapy. MATERIALS AND METHODS: This study included adult women with acute uncomplicated cystitis who visited 4 institutions between 2019 and 2020. After registration, we administered oral antibiotics and prospectively documented the changes in lower urinary tract symptoms from the first visit to a follow-up visit at 1 week using the Core Lower Urinary Tract Symptoms Score (CLSS) questionnaire...

BACKGROUND: The lack of overall experience and reporting on angiographic findings in previously published studies of renal arterial embolization (RAE) compelled us to report our overall experience on a series of patients. MATERIALS AND METHODS: A retrospective study was performed analyzing data of patients enrolled for RAE between 2010 and 2019. History, physical examination, and laboratory data were reviewed for all patients. Abdominal ultrasound was the initial imaging study, and all patients underwent subsequent computed tomography or magnetic resonance imaging...

Ureteroscopy during pregnancy has become increasingly recognized as a safe intervention. Performing it under local anesthesia and light sedation reduces the risks associated with general or regional anesthesia, such as difficult airway scenarios, hypothermia, and hypotension. In addition, this approach reduces the total amount of fetal exposure to medications and anesthetic agents. Performing ureteroscopy in this manner requires a number of adjustments and modifications to the standard technique. This article provides a summary in a step-by-step format, as well as an accompanying video demonstration...

BACKGROUND: An increase in life expectancy has led to an increased elderly population. In turn, this aging population is more likely to develop health conditions, such as pelvic floor disorders (PFDs). This study aimed to assess the prevalence of these disorders and the associated quality of life in institutionalized and noninstitutionalized elderly women. MATERIALS AND METHODS: A cross-sectional study was conducted with 80 female participants older than 60 years, divided into 2 groups: institutionalized and noninstitutionalized participants...

Two cases of penile metastasis from primary prostate cancer in a single center are presented, along with a literature review and description of the excision technique. Despite its rich vascularization, penile metastasis is rare, with 72 new cases from September 2006 to March 2021. There is a wide variety of diagnoses, treatments, and prognoses for penile metastatic lesions. Ga-68 prostatespecific membrane antigen positron emission tomography/computed tomography is the most sensitive imaging tool for detecting metastasis from primary prostate cancer...

BACKGROUND: To evaluate the effectiveness and safety of cabazitaxel in castration-resistant prostate cancer patients aged ≥80 years, we performed a retrospective study on a sample of patients from 11 Italian cancer centers. MATERIALS AND METHODS: Fifty-seven patients aged ≥80 years were treated with cabazitaxel after previous failure with docetaxel; 39 completed a comprehensive geriatric assessment questionnaire (34 fit and 5 vulnerable) and 8 patients (14%) had an Eastern Cooperative Oncology Group performance status (PS) ≥2, while most had a PS of 0-1 (86%)...

BACKGROUND: Numerous surgical techniques are available for the correction of isolated ventral congenital penile curvature (IVCPC). This study aimed to assess the outcomes and predictors of IVCPC treatment in adults using an incisionless plication technique. MATERIALS AND METHODS: This prospective case series examined patients with IVCPC who were treated in our hospital between October 2017 and February 2020 using incisionless plication of the tunica albuginea (Essed-Schroeder technique) with a covering pair of absorbable sutures...

The aim of this systematic review is to compare the benefits and risks of these management options. METHODS: MEDLINE, EMBASE, and Cochrane Library databases were searched from inception to February 2022. A total of 516 nonduplicate studies were screened against the inclusion and exclusion criteria...

BACKGROUND: To evaluate the predictive values of Prostate Imaging Reporting and Data System version 2 (PI-RADS v2), prostate-specific antigen (PSA) level, PSA density (PSAD), digital rectal examination findings, and prostate volume, individually and in combination, for the detection of prostate cancer (PCa) in biopsy-naive patients. METHODS: We retrospectively analyzed 630 patients who underwent transrectal systematic prostate biopsy following prostate multiparametric magnetic resonance imaging...

BACKGROUND: Targeted magnetic resonance (MR) with ultrasound (US) fusion-guided biopsy has been shown to improve detection of prostate cancer. The implementation of this approach requires integration of skills from radiologists and urologists. Objective methods for assessment of learning curves, such as cumulative sum (CUSUM) analysis, may be helpful in identifying the presence and duration of a learning curve. The aim of this study is to determine the learning curve for MR/US fusion-guided biopsy in detecting clinically significant prostate cancer using CUSUM analysis...
