Abstract: Background: Bladder pain syndrome/interstitial cystitis (BPS/IC) can cause pelvic pain, frequent urination, and a strong urge to urinate. These symptoms can significantly reduce quality of life, causing psychological distress, sexual dysfunction, poor sleep quality, decreased work productivity, and increased morbidity. Despite the prevalence of this condition, determining the most effective treatment guidelines for BPS/IC remains a challenge due to the complexity of its pathogenesis. Objective: Understanding cellular and molecular aspects is essential to explore different cell types in changes in function and sensitivity of the urothelial layer and chronic inflammation. Main Ideas: Cellular aspects in the pathogenesis of BPS/IC include Umbrella Cells, Basal and Intermediate Cells, Paraneuron Cells, Myofibroblasts and Telocytes, Detrusor Smooth Muscle Cells, Nerve Cells, Astrocytes, Microglia, CD68+ Macrophages, CD74+ Lymphocytes, Eosinophils, and Mast Cells. Disruption of these cells leads to altered urothelial barrier function, sensitivity, and chronic inflammation. Molecular aspects include chronic inflammation with increases in p38-mitogen activated protein kinase (p38 MAPK), Interleukin-1β (IL-1β), Interleukin-6 (IL-6), Tumor Necrosis Factor-α (TNF-α), Nerve Growth Factor (NGF), Brain-Derived Neurothropic Peptide (BDNF), and other molecules. Conclusion: Changes in the urothelial barrier and bladder wall sensitivity are also significant. Complex interactions between the immune and nervous systems contribute to chronic inflammation through positive feedback. Therefore, this article aims to understand the cellular and molecular aspects that play a role in the pathogenesis of BPS/IC and help provide appropriate treatment.

Abstract: Metastasis of prostate cancer to the testes is a rare phenomenon, often indicating advanced-stage disease. This case report details a 79-year-old man with a history of prostate cancer, who underwent endoscopic-extraperitoneal radical prostatectomy and bilateral pelvic lymph node dissection. The patient subsequently received radiation therapy for local recurrences. Thirteen years post-surgery, a testicular ultrasound revealed a cystic mass in the left testis, initially suspected to be a primary neoplasm. However, pathology with immunohistochemical analyses confirmed metastasis from prostate adenocarcinoma. Testicular metastasis of prostate cancer is uncommon, underscoring the aggressiveness and potential spread of the tumor. Clinically evident testicular metastases develop in only a small percentage of prostate cancer patients. This case report highlights the importance of considering metastatic disease in the differential diagnosis of testicular masses and the necessity of clinicopathologic correlation in such evaluations. Early detection and accurate diagnosis are crucial for managing testicular metastasis and improving patient outcomes. The case also emphasizes the significance of long-term follow-up in prostate cancer patients, as metastasis can occur many years post-initial treatment. Furthermore, it illustrates the critical role of advanced imaging techniques and thorough pathological assessments in identifying and managing metastatic spread. This report contributes to the limited but growing body of literature on testicular metastasis from prostate cancer, providing insights for clinicians in recognizing and managing this rare but serious complication. It underscores the need for ongoing research to better understand the mechanisms of metastatic spread and develop targeted therapeutic strategies.

Abstract: Background: Urinary bladder lesions, non-neoplastic and neoplastic, are collectively responsible for significant morbidity and mortality throughout the world. Bladder cancer is a prevalent disease affects a significant number of individuals each year worldwide. The most common non-neoplastic and neoplastic lesion of the urinary bladder is non-specific cystitis and urothelial carcinoma respectively. Objectives: The aim of this study is to describe histopathologic patterns of urinary bladder lesions and associated risk factors in Hawassa University Comprehensive Specialized Hospital from January 2017 to December 2023. Methods: A 7-year cross sectional study was conducted to describe histologically diagnosed bladder lesions and associated factors at Hawassa University Comprehensive Specialized Hospital from January 2017 to December 2023. Results: This study comprised a total of 182 patients who have bladder biopsies at Hawassa University Comprehensive Specialized Hospital, Pathology department from January 2017 to December 2023. Out of which 21 cases (12.1%) are non-neoplastic, while 152 cases (83%) are neoplastic. Nine cases (4.9%) have a descriptive diagnosis. With 139 (90.44%) cases, urothelial neoplasms have the highest frequency form all neoplastic lesions. Ninety-seven cases, or 69.8%, of urothelial neoplasms were invasive; of them, 78 (80.4%) were high grade cases. Low-grade noninvasive papillary carcinomas, which accounted for 24 instances. One case is a cystectomy specimen, and the remaining 181 cases are TURBT. The age range of 50-59 years was the most frequent accounting for 39 (21.4%) of all cases, with a male to female (M: F) ratio of 2.9:1. The most frequent presenting symptom in 146 (85.7%) of patients was hematuria. Conclusions: This study demonstrates that 139 (90.44%) of the neoplastic bladder lesions were bladder neoplasms of urothelial origin, 97 (69.8%) of which are invasive urothelial carcinoma with rising numbers each year and implying the burden in the region.

Abstract: Late recurrence (LR) of bladder cancer after radical cystectomy (RC) is rare, and few studies have been conducted. We report a case of local LR of bladder cancer 10.3 years after RC. The pathology at RC was almost carcinoma in situ (CIS) only. The patient underwent metastasectomy, and treatment with an immune checkpoint inhibitor (ICI) achieved a complete response (CR). A 61-year-old woman was referred to our hospital for macrohematuria and bladder irritability in June 2012. She underwent RC along with pelvic lymph node dissection and ileal conduit creation. The pathologic findings were CIS, G2>G3, pT1, pN0. She visited our hospital with complaints of lower abdominal discomfort in November 2022, and recurrence was found on the pelvic floor by abdominal computed tomography. Metastasectomy confirmed metastasis of urothelial carcinoma. As salvage therapy, systemic chemotherapy with a platinum agent and an ICI were administered, leading to CR. Long-term follow-up should be considered for patients with bladder cancer, even for early-stage CIS-only tumors. Metastasectomy could be the primary option for LR of bladder cancer after RC.

Abstract: Background: According to Globocan 2020, the global burden of cancer has increased to 19.3 million cases and 10 million cancer deaths. The International Agency for Research on Cancer estimates that, in the world, one in five people develop cancer during their lifetime. Urinary tract cancers are common in urology. They are most often of a bad prognosis. While the epidemiology of urological cancers is well known in the Northern Countries, data on these conditions are little available or insufficient. The purpose of this study was to determine the frequency of urological cancers, describe their clinical presentation and classification. Methodology: We conducted a transversal study in the urology, oncology and pathology anatomy departments of the Douala General Hospital (DGH) and the Douala Laquintinie Hospital (DLH). Medical records and pathology reports of biopsies carried out on patients with urological cancer and hospitalized over a period of 10 years from January 1, 2010 to December 31, 2019 were included. Results: A total of 93 cases were selected. The sex ratio of 8:1. The average age was 64.7±11.51 years for men and 45.8±23 years for women (p=0.030). Smoking was the main comorbidity (30.1%). Low back pain, hematuria and urine retention were the main modes of revelation. Prostate cancer was found in 75.3%. Prostate adenocarcinoma was the most found histological type (94.1%) Kidney, bladder and penis cancer were found in 16.1%; 7.5% and 1% of cases. More than half of patients with prostate cancer (68.6%) had metastasis at the time of diagnosis. Conclusion: urological cancers affect men more. The symptomatology is dominated by the signs of the upper and lower urinary tract. Prostate adenocarcinoma is the most found histological type.
