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 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 >

Abstract Benign prostatic hyperplasia (BPH) represents a prevalent etiology of lower urinary tract symptoms (LUTS) in the male population, clinically defined by a non-malignant proliferation of prostatic tissue. While BPH exhibits a high prevalence among older male populations globally, the precise underlying mechanisms contributing to its development remain incompletely elucidated. Mitochondria, essential organelles within eukaryotic cells, are critical for cellular bioenergetics, the regulation of reactive oxygen species (ROS) generation, and the modulation of cell death pathways. The maintenance of mitochondrial homeostasis involves a complex interplay of processes. By synthesizing previous literature, this review discusses mitochondrial homeostasis More >

Abstract Objectives: Benign prostatic hyperplasia (BPH) is a common benign tumor in men, with an age-related prevalence of multifactorial etiology. The present study aimed to accurately assess and predict the effect of co-existing metabolic syndrome (MtS) upon treatment outcomes of combination medical therapy in select patients of lower urinary tract symptoms (LUTS) due to BPH. Methods: After obtaining informed consent from the patients, 70 eligible patients with LUTS due to BPH with and without MtS were enrolled in this study from September 2022 to January 2024 from the outpatient clinic at the University College of Medical… More >

Abstract While cystolitholapaxy for bladder stones is commonly performed using a transurethral approach, large or complex stone burdens in patients with complex lower urinary tract anatomy may make this inefficient or infeasible. Percutaneous cystolitholapaxy is a safe, effective, minimally invasive alternative for diverse indications, including patients with benign prostatic hyperplasia, urethral stricture disease, closed bladder neck, continent catheterized channel, or other urinary diversion. In this article, we review the indications for and advantages of percutaneous cystolitholapaxy and describe our step-by-step technique for this procedure, including representative imaging and favored equipment. We also discuss preoperative and postoperative More >

Abstract Tumor-to-tumor metastasis (TTM) is a rare phenomenon in which a secondary tumor colonizes within a primary tumor of a different histogenesis. It is hypothesized that TTM is encouraged by conditions that promote increased cell growth and division in the primary tumor, such as hypervascularity and expression of oncogenic cytokines. However, the exact causes of TTM likely vary on a case-by-case basis and are dependent on the microenvironment of both the primary and secondary tumors. Herein, we present the first reported example of TTM in which a pulmonary neuroendocrine tumor (NET) metastasizes to a renal oncocytoma. More >

Abstract Introduction: Benign prostatic hypertrophy (BPH) is a common condition affecting men later in life, significantly impacting quality of life (QOL). Surgical intervention is often pursued when medical management fails, but patient satisfaction with outcomes varies. Decisional regret can affect perceived success and patient satisfaction post-surgery. This study evaluates the relationship between post-surgical symptoms and decisional regret across BPH procedures. Methods: A prospective, multicenter cohort study included 54 patients undergoing BPH surgery between March 2023 and February 2024. Patients completed the International Prostate Symptom Score-QOL (IPSS-QOL) scale preoperatively and at least three months postoperatively, along with… More >

Abstract Introduction: Distal ureteral obstruction has classically been managed by ureteroneocystostomy (UNC). The feasibility and success of robotic primary ureteroureterostomy (UU) for benign obstruction appears promising with several benefits over UNC but is poorly studied. Robotic repair offers superior visualization and precision, allowing for minimal ureteral dissection. Here we report on our experience and short-term outcomes. Materials and Methods: We identified patients who underwent robotic distal ureteroureterostomy for benign distal ureteral obstruction at our institution from 2020–2024. Etiology, stricture length, and post-operative outcomes were recorded. All patients had renal ultrasound (US), diuretic renography, or cross-sectional imaging within… More >

Abstract Introduction: Holmium Laser Enucleation of the Prostate (HoLEP) is a size-independent, endoscopic management option for benign prostatic hyperplasia (BPH). HoLEP offers a distinct advantage for patients who are at high-risk for bleeding whilst preserving prostatic tissue for pathology analysis, unlike photoselective vaporization. Further, HoLEP avoids the need for cystotomy, unlike simple open and robotic prostatectomy, by using intravesical morcellation. We report our experience with the first 1000 HoLEP procedures at our institution. Materials and Methods: We performed a retrospective review of all HoLEP procedures performed at our institution from 2013–2021 to capture patient demographics, procedure details,… More >

Abstract Holmium laser enucleation of the prostate (HoLEP) is considered a size-independent technique to treat benign prostatic hyperplasia. This safe and effective procedure is increasingly being adopted in urology training programs worldwide, yet limited teaching strategies have been described. Endoscopic handling during HoLEP allows for a simultaneous interaction between the surgeon and trainee, facilitating a guided teaching strategy with increasing difficulty as experience grows. In this article, we describe our stepwise approach for teaching HoLEP as part of a structured surgical training curriculum. We also evaluate the association of our method with intraoperative efficiency parameters and More >
