Background/Objectives: Bladder cancer is a common malignancy with a high rate of recurrence and progression. Recent studies have identified that the urinary microbiome can be a key factor in tumor pathogenesis, progression, and outcomes. This narrative review is designed to summarize current evidence regarding the urobiome and explore its diagnostic and therapeutic potential. Methods: Studies between 2019 and 2024 were identified through the PubMed/MEDLINE and Google Scholar databases. Case reports and non-English-language articles were excluded. Results: The main findings revealed that specific bacteria, viruses, and taxa are linked to bladder cancer presence, progression, and response to immunotherapy treatment. Urinary microbiota differ by tumor type, sex, smoking status, and occupational exposure to toxins. Conclusions: Urinary microbiome and certain types of viruses present in urine may serve as promising tools to enhance bladder cancer diagnosis and predict treatment response. However, larger longitudinal studies are needed to confirm and establish these findings. Furthermore, integration of the urinary microbiome in clinical practice and public health strategies may reduce disease-related burden.

Background: Tumour volume percentage (TVP) is considered an important pathological parameter, particularly in prostate cancer, representing the ratio of tumour volume to the total gland, and it can be used to measure the quantity of malignancy. Previous reports have already demonstrated that an elevated tumour volume percentage is associated with unfavourable factors, including extraprostatic extension, positive surgical margins, and lymph node metastasis. The independent value of TVP, especially in high-risk prostate cancer treated by radical prostatectomy, remains an area of active research, despite established prognostic factors such as PSA, ISUP grade, and TNM stage. Materials and Methods: We retrospectively analyzed the records of 159 high-risk prostate cancer patients who underwent open or laparoscopic radical prostatectomy between January 2016 and January 2025 at the Clinic of Urology of Targu Mures. High-risk patients were defined as those with ISUP grade 4–5 or PSA >20 ng/mL or clinical stage ≥T2c or stage cT3–4 and/or lymph node metastasis. Tumour volume percentage was calculated from the final pathology result and was determined as the proportion of prostate cancer volume relative to the total prostate volume. Clinical and pathological features, including PSA, ISUP grade, TNM stage, surgical margin, and lymph node involvement, were reported. To assess TVP as an indicator of tumour aggressiveness, univariate and multivariate regression analyses were performed. A p-value < 0.05 was considered statistically significant. Results: A total of 159 high-risk prostate cancer patients (100%), with a median age of 66 years, who underwent open or laparoscopic radical prostatectomy were included. The median tumour volume percentage was 7.6%, and the median prostate volume was 43.8 cc. On univariate analysis, patients with extraprostatic extension (p < 0.001), positive surgical margins (p = 0.005), a higher ISUP grade (p < 0.001), and lymph node metastasis (p = 0.006) exhibited higher TVP compared to their counterparts. A significant correlation was also observed between TVP and the number of positive biopsy cores (p < 0.001), a higher PSA value (p = 0.005), and a younger age (p = 0.041). Conversely, no correlation was identified between TVP and perioperative factors such as hospital stay, surgery duration, ICU days, type of approach, or positive urine culture. Two regression models on multivariate analyses were performed with TVP as the dependent variable. In the continuous variable model (Adjusted R2 = 0.43, p < 0.001), independent predictors of higher TVP were the number of positive biopsy cores (B = 0.54, p < 0.001), the number of positive lymph nodes (B = 2.59, p < 0.001), and surgical margin dimension (B = 1.19, p < 0.001). Age, PSA, and perioperative variables showed no significant correlation with TVP on multivariate analysis. In the categorical regression model (Adjusted R2 = 0.438), statistical significance was confirmed (F-test, p < 0.001). Independent predictors of increased tumour volume percentage included ISUP grade 5 in the effect-coded model (B = +6.60, 95% CI: 0.96–12.25, p = 0.022), and pathological TNM stage pT4 (B = +24.70, 95% CI: 17.69–31.70, p < 0.001). ROC analysis showed limited-to-moderate discrimination for positive surgical margins (AUC = 0.655; 95% CI 0.565–0.744; p = 0.001) and stronger discrimination for pN1 (AUC = 0.793; 95% CI 0.650–0.936; p = 0.002). The Youden-derived cut-offs were 4.90% for positive surgical margins and 5.77% for lymph-node metastasis. Conclusions: Tumour volume percentage is significantly associated with several adverse pathological features in high-risk prostate cancer. Rather than a standalone biomarker, its association with adverse pathological features underscores its potential role in risk stratification models, and the incorporation into pathology reports and prognostic nomograms may improve clinical decision-making.

Background/Objectives: A variant of autism spectrum disorder (ASD) known as Asperger syndrome (AS) shows increasing incidence worldwide, affecting between 0.02% and 0.03% of children. Patients display abnormal conduct, are limited in social interaction and communication, and are more often affected by micturition disorders, incontinence, and voiding symptoms than typically developing children. Methods: The present study aimed to review the literature related to the current management of lower urinary tract conditions in children with Asperger syndrome and to present a case of a 14-year-old girl with ASD, with characteristic impairments, including communication challenges, stereotyped, repetitive behaviors, and chronic constipation with concomitant bladder dysfunction, presenting recurrent urinary tract infections (UTIs) and lower urinary tract symptoms (LUTS), including voiding and filling storage symptoms. For the AS, she was treated with a selective serotonin reuptake inhibitor (Sertraline). An abdominal ultrasound, PLUTTS—pediatric lower urinary symptoms scoring (21); QL-quality of life (3); voiding diary; and uroflowmetry were performed, revealing an incomplete urinary retention (incomplete bladder emptying of 120 mL), a prolonged and interrupted curve, a maximum urinary flow rate (Qmax) 7 mL/s, and a UTI with Enterococcus. Results: Besides psychiatric reevaluation and antibiotic therapy, functional magnetic stimulation (FMS) sessions were performed. After eight sessions (20 min, 35 MHz, every second day), the ultrasound control and the uroflowmetry showed no residual urine, and the Qmax was 17 mL/s. The curve continued to be interrupted: PLUTSS-11, QL-1. FMS was continued at two sessions per week. At the 3-month follow-up, no residual urine was detected, and Qmax reached 24 mL/s. Conclusions: ASD is an incapacitating/debilitating condition that significantly impairs social functioning. In many cases, in addition to psychological symptoms, other conditions such as LUTS and constipation may coexist. Antipsychotics and antidepressants are frequently prescribed for these patients, often leading to various side effects, including micturition disorders. Therefore, screening for LUTS is recommended, and, if indicated, treatment—especially non-pharmacological and non-invasive approaches, such as FMS—should be considered.

Background/Objectives: We developed and internally validated the Bladder Risk Index using Clinical and Systemic biomarkers (BRICS), a preoperative prediction model designed to estimate the likelihood of high-grade (HG) disease and muscle-invasive bladder cancer (MIBC) in patients undergoing their first transurethral resection of bladder tumor (TURBT). Methods: This retrospective single-center study included 161 patients with newly diagnosed urothelial bladder cancer. The BRICS-HG model included tumor size, neutrophil-to-lymphocyte ratio (NLR), and creatinine-to-hemoglobin ratio (CHR), while the BRICS-MIBC model was based on tumor size and NLR. Model performance was assessed in terms of discrimination, calibration, and Brier score, together with exploratory decision curve analysis. Internal validation was performed using 2000 bootstrap resamples. Results: MIBC was identified in 20 patients (12.4%). BRICS-HG demonstrated limited discriminatory ability, with an apparent AUC of 0.649 and an optimism-corrected AUC of 0.623 (95% bootstrap interval: 0.541–0.703). BRICS-MIBC achieved moderate discrimination, with an apparent AUC of 0.735 and an optimism-corrected AUC of 0.709 (95% bootstrap interval: 0.588–0.826). Across the bootstrap resamples, the model combining tumor size and NLR was selected in 53.9% of cases, reflecting uncertainty in predictor selection. Conclusions: BRICS-HG should be regarded as an exploratory model, and its current performance does not support clinical application. BRICS-MIBC demonstrated moderate discrimination after internal validation; however, its performance should be interpreted cautiously given the small number of MIBC events. Validation in larger, independent cohorts, ideally across multiple centers, is necessary before the model can be considered for clinical implementation.

Background and Objective: Children’s lower urinary tract dysfunction (LUTD) is a frequently diagnosed condition. Initial management measures, such as parental education, urotherapy, and constipation management, followed by drug-based and surgical therapies, are well known. In recent years, different electrical, transcutaneous nerve stimulation methods (sacral, tibial, and intravesical) were studied, and magnetic stimulation has gained importance in the treatment of lower urinary tract dysfunctions. This review aimed to examine the efficacy of functional magnetic stimulation in treating children’s LUTD. Materials and Methods: Our review was carried out in the following databases: PubMed/Medline and Google Scholar. Results: We limited our search to articles published in the last 8 years (2018–2025). Our used keywords were: “functional magnetic stimulation, electrical stimulation, children’s lower urinary tract dysfunction, children’s overactive bladder, enuresis”. The final search revealed a total of 132 results; articles written in languages other than English were excluded. In the end, a total of 16 articles presenting ES (12 articles) and FMS (four articles) in the treatment of children’s lower urinary tract dysfunction were included in our narrative review. Conclusions: In spite of a few clinical controlled trials, our review concerning functional magnetic stimulation (FMS) provides acceptable evidence to support the efficacy of these methods among the pediatric population. In the future, large sample, randomized controlled trials are needed in this field.

Secondary lymphoma of the prostate is described as the involvement of the prostate gland by lymphomatous spread from a primary site. This condition is exceedingly rare and often presents diagnostic and therapeutic challenges. The symptoms often mimic those of benign prostatic hyperplasia or prostate cancer, including LUTS (lower urinary tract symptoms) and even complete urinary retention. Here, we present a rare case of a 62-year-old male patient undergoing chemotherapy for stage IV mantle cell stomach lymphoma and subsequently secondary prostatic involvement. The patient presented with complete urinary retention, accompanied by biochemical (PSA = 11.7 ng/mL) and imaging (Magnetic Resonance Imaging-PIRADS V lesion) suspicion for prostate cancer. Histopathologic analysis of the MRI-targeted prostate fusion biopsy revealed secondary prostatic lymphoma. The chosen treatment was transurethral resection of the prostate (TUR-P) for relief of symptoms, which significantly improved urinary function (postoperative IPSS = 5 and Qmax = 17 mL/s). This case underscores the importance of considering prostatic lymphoma in the differential diagnosis of bladder outlet obstruction, especially in patients with a known lymphoma history. This report also provides a focused review of the literature on secondary prostatic lymphoma, highlighting the diagnostic challenges, treatment options, and clinical outcomes.
