Abstract Late-onset hypogonadism (LOH), characterized by the intersection of aging and androgen deficiency, impacts the health of approximately 2%−39% of middle-aged and elderly men, underscoring the need for comprehensive research. Animal models, serving as analogs of human diseases, are indispensable for investigating disease mechanisms and facilitating drug development. However, the diverse array of animal models utilized for LOH research has led to a lack of standardized modeling approaches and evaluation systems, potentially impeding progress in understanding the pathogenesis and therapeutic development. In this paper, we summarize and compile the characteristics, methods, and evaluation systems of rodent More >

Abstract In recent years, the introduction of the Da Vinci Single Port (SP) robotic platform has opened new doors for the treatment of localized renal masses. This technology, particularly when utilized via a regionalized retroperitoneal (RP) approach, offers several distinct advantages that may improve patient recovery. These advantages include easier access to both anterior and posterior renal tumors, avoidance of the peritoneal cavity with complicating adhesions, and simplified supine positioning, potentially reducing the risk of musculoskeletal or nerve injuries. Yet, the learning curve for RP surgery remains steep due to the unfamiliarity of many surgeons with More >

Abstract Overview: Freehand transperineal prostate biopsy (TPPB) needle guides are designed to maintain a parallel alignment between the co-axial introducer needle and the ultrasound (US) transducer. However, this parallel alignment necessitates transducer angulations within the patient’s rectum for sampling anterior or posterior regions of the prostate, which introduces several problems both for the patient and the operator. This article introduces a technique using a TPPB needle guide system with a novel angle-adjustment feature, which minimizes intrarectal transducer movements. Objectives: Freehand TPPB typically requires anterior or posterior angulation of the ultrasound (US) transducer, which leads to prostate More >

Abstract Background: Aquablation is a robotic-assisted, water jet-based transurethral therapy for benign prostatic hyperplasia (BPH). Concerns about postoperative hematuria led to the practice of limited transurethral resection (TUR) with cauterization. This study aimed to assess the impact of tranexamic acid (TXA) on hematuria outcomes when combined with limited TUR after Aquablation. Methods: We retrospectively analyzed men undergoing Aquablation at our institution (October 2020–July 2024). Demographic, prostate, surgical, and hematuria outcomes were extracted from electronic medical records. Kruskal-Wallis test compared medians. Results: Of 131 patients, 113 (86%) had limited TUR; 31 (27%) received 1 g TXA perioperatively. TXA… More >

Abstract Background: Epithelioid angiomyolipoma (EAML) is an uncommon renal tumor variant with histologic and radiologic features that can mimic renal cell carcinoma (RCC) on imaging due to the paucity of fat compared to the classic AML. EAML may exhibit aggressive behavior, including local invasion, recurrence, and distant metastases to the liver, lungs, and lymph nodes. Although recent reports suggest that up to one-third of EAML cases may behave malignantly, variability in diagnostic criteria and limited case series contribute to uncertainty regarding its true clinical course.

Abstract Introduction: Spermatocelectomy is a surgical procedure performed for symptomatic spermatoceles. Published data is limited with respect to recurrence rates, complication rates, and patient satisfaction. The core concept of spermatocelectomy is to identify the communication between epididymis and spermatocele, which can be difficult and may result in spermatocele recurrence. We postulate that a combined spermatocelectomy with epididymectomy will yield a lower rate of recurrence. Methods: A retrospective chart review of patients with symptomatic spermatoceles undergoing spermatocelectomy with or without epididymectomy at our institution was performed. Patients were excluded from epididymectomy if they were interested in fertility… More >

Abstract Objectives: Treatment of patients with lower urinary tract symptoms (LUTS) is often challenging. In men, the origin of LUTS, in particular overactive bladder (OAB) symptoms, is often due to prostate enlargement. However, patients with chronic prostate inflammation (CPI) also frequently experience OAB. Thus far, it is not known if the inflammation per se or concomitant prostate enlargement is the underlying cause of LUTS. Currently, we aim to examine if there is any correlation between CPI and the persistence of OAB symptoms in patients with benign prostate hyperplasia (BPH). Methods: Fifty-one men underwent transurethral resection of… More >
