Background & Objectives: In bladder outlet obstruction-induced rat models, the transforming growth factor-beta (TGF-β) and collagen ratios have been shown to be increased. Increased TGF-β leads to fibrosis. In this study, the effect of omega-3 and interferon alpha-2b (IFN α-2b) was investigated on oxidative stress, inflammation and fibrosis in bladder structure in a partial bladder outlet obstruction (PBOO) rat model.
Methods: A total of 35 male Wistar albino rats, weighing 300-350 g, were used in the study. The rats were randomly divided into five groups. At the end of the experimental period, bladders were harvested from all the rats, and pathological analysis of the rat bladder tissues was performed. In addition, investigations were carried out with enzymatic and non-enzymatic antioxidant systems to study the antioxidant properties of omega-3 fatty acid and IFN alpha-2b.
Results: Increased bladder weight in the PBOO group, in comparison to the control group, was decreased by the administration of omega-3 and IFN α-2b (P=0.002). Significantly higher superoxide dismutase (SOD) levels were detected in group 2 in comparison to the control group. It was also detected that serum SOD, glutathione peroxidase and nitric oxide (NO) levels were significantly higher in group 2 when compared to the control group (P<0.05). In the pathologic evaluation, group 2 showed significantly increased inflammation and fibrosis compared to the control group. Omega-3 treatment significantly decreased inflammation. It was shown that IFN α-2b application partially decreased inflammation.
Interpretation & Conclusions: The results of the present study showed that in addition to the standard primary approaches to prevent the damage to the upper urinary tract secondary to PBOO, omega-3 fatty acid and IFN α-2b could be beneficial as adjunct treatment in clinical practice. However, this needs to be further investigated with prospective, randomized clinical trials with larger sample sizes.

Hemostasis is a critical aspect of holmium laser enucleation of the prostate (HoLEP) for benign prostatic hyperplasia (BPH). While HoLEP offers superior outcomes compared to traditional techniques, effective intraoperative and postoperative bleeding control remains a challenge. This report evaluates the feasibility and safety of PuraBond® (3-D Matrix, Ltd.

Introduction And Objective: Urodynamic study (UDS) is required to diagnose bladder outlet obstruction (BOO) during evaluation of benign prostatic hyperplasia (BPH) but is seldom performed due to cost and invasiveness. Therefore, anatomic and clinical parameters to predict BOO have been proposed, including the prostate transition zone index (TZI) which is the ratio of prostate transition zone volume (TZV) to whole gland volume (WGV). Historically computed with ellipsoid volume estimation of prostate WGV and TZV from transrectal ultrasound measurements, controversy exists regarding the utility of TZI to predict likelihood of BOO on UDS and clinical outcomes following BPH surgery.

Introduction And Objectives: Laser vaporization techniques have emerged as a prominent alternative to transurethral prostate resection in managing benign prostatic obstruction (BPO). This study focuses on assessing the effectiveness of the ejaculatory preserving laser vaporization of the prostate technique compared to the conventional non-ejaculatory approach in managing BPO.
Patients And Methods: Our study was performed between August 2022 and September 2023.

Purpose: To compare voiding parameters in women with and without increased postvoid residual (PVR) volume, to correlate these parameters with PVR volume and PVR percentage, and to describe their ability to predict an increased PVR volume.
Methods: Retrospective cross-sectional study of urodynamics data prospectively acquired from consecutive symptomatic women over a 5-year period. Patients with spinal cord disorders and with abdominal straining during voiding (abdominal pressure ≥10 cm H2O over baseline at maximum flow rate [Qmax]) were excluded.
Introduction: Solitary fibrous bladder tumors are extremely uncommon, with only a few cases reported. These fibroblastic mesenchymal neoplasms are typically benign, indolent, and slow growing.
Case Presentation: A 44-year-old male patient with obstructive uropathy was referred to our unit for workup.
