Primary endpoints were time from treatment initiation to discontinuation/switching; proportion who discontinued/switched; and reasons for discontinuation/switching.

Intelligent Bladder Volume Monitoring for Wearable Ultrasound Devices: Enhancing Accuracy Through Deep Learning-Based Coarse-to-Fine Shape Estimation.

Accurate and continuous bladder volume monitoring is crucial for managing urinary dysfunctions. Wearable ultrasound (US) devices offer a solution by enabling noninvasive and real-time monitoring. Previous studies have limitations in power consumption and computation cost or quantitative volume estimation capability.

Methods: Patients who underwent HoLEP between January 2010 and April 2020 at Seoul National University Hospital were analyzed. SPs were defined as cases of conversion to resection of the prostatic tissue using an electrosurgical loop after morcellation or secondary morcellation a few days after surgery or conversion to open cystotomy.

Efficacy and safety of low power holmium laser enucleation of the prostate: A prospective short- and medium-term single-blind randomized trial.

Purpose: We evaluated the efficacy and safety of mid-term follow-up in low-power (LP) Holmium laser enucleation of the prostate (HoLEP) compared with high-power (HP) surgery for benign prostatic hyperplasia (BPH).

Materials And Methods: This prospective, single-blind, randomized controlled study was conducted between September 2020 and April 2021. Ninety male patients >50 years who underwent HoLEP for BPH were randomly assigned to HP (80 W/2 J/40 Hz) and LP (24 W/2 J/12 Hz) groups.

Autonomic responses during bladder hydrodistention under general versus spinal anaesthesia in patients with interstitial cystitis/bladder pain syndrome: a randomized clinical trial.

Blocking the abrupt increase in systolic blood pressure associated with autonomic response during bladder hydrodistention in patients with interstitial cystitis/bladder pain syndrome (IC/BPS) is essential for patient safety. We conducted this study to compare autonomic responses during bladder hydrodistention in patients with IC/BPS under general and spinal anaesthesia. Thirty-six patients were randomly allocated to a general anaesthesia (GA, n = 18) or a spinal anaesthesia (SA, n = 18) group.

Does Preoperative Bladder Compliance Affect Long-Term Functional Outcomes after Laser Prostatectomy?

Purpose: We assessed the effects of preoperative bladder compliance on the long-term functional outcomes, especially focused on postoperative storage symptom changes, after laser prostatectomy.

Materials And Methods: From January 2008 to March 2014, 1,608 men who underwent laser prostatectomy, including holmium laser enucleation or photo-vaporization of the prostate, were included in the analysis. We divided patients into 3 groups according to bladder compliance on a baseline urodynamic study: <12.

Natural history of incidentally diagnosed prostate cancer after holmium laser enucleation of the prostate.

Objectives: There is no consensus on the management plan for incidental prostate cancer (IPCa) after holmium laser enucleation of the prostate (HoLEP). This study aims to investigate the natural course of this disease and suggest appropriate treatment in real clinical practice.

Maximum Voided Volume Is a Better Clinical Parameter for Bladder Capacity Than Maximum Cystometric Capacity in Patients With Lower Urinary Tract Symptoms/Benign Prostatic Hyperplasia: A Prospective Cohort Study.

Purpose: Bladder capacity is an important parameter in the diagnosis of lower urinary tract dysfunction. We aimed to determine whether the maximum bladder capacity (MCC) measured during a urodynamic study was affected by involuntary detrusor contraction (IDC) in patients with Lower Urinary Tract Symptoms (LUTS)/Benign Prostatic Hyperplasia (BPH).

Methods: Between March 2020 and April 2021, we obtained maximum voided volume (MVV) from a 3-day frequency-volume chart, MCC during filling cystometry, and maximum anesthetic bladder capacity (MABC) during holmium laser enucleation of the prostate under spinal or general anesthesia in 139 men with LUTS/BPH aged >50 years.

Outcome of Patients With Elevated Prostate-Specific Antigen and Lower Urinary Tract Symptoms Receiving Holmium Laser Enucleation of the Prostate.

Purpose: This study investigated functional outcomes in lower urinary tract symptoms (LUTS), the incidence of incidental prostate cancer (PCa), and changes in prostate-specific antigen (PSA) levels after holmium laser enucleation of the prostate (HoLEP) in patients with elevated PSA and benign prostatic hyperplasia (BPH).

Methods: A retrospective review of a prospectively designed protocol for patients who underwent HoLEP at our institution from January 2010 to May 2020 was conducted. Patients were classified into low-PSA (<3.

Risk Factors for Transurethral Coagulation for Hemostasis During Holmium Laser Enucleation of the Prostate.

Purpose: We aimed to identify risk factors for transurethral coagulation (TUC) using bipolar electrocautery for hemostasis during holmium laser enucleation of the prostate (HoLEP) surgery for benign prostatic hyperplasia (BPH).

Methods: We analyzed the clinical outcomes of HoLEP surgery performed by a single surgeon between January 2010 and April 2020 at the Seoul National University Hospital. Patient characteristics and perioperative parameters were used to identify the risk factors for TUC.

Translation and Linguistic Validation of Korean Version of the Expanded Prostate Cancer Index Composite for Clinical Practice for Patients With Prostate Cancer.

Purpose: Advances in the diagnosis and treatment of prostate cancer have increased the patients' stress level and decreased the quality of life. A variety of instruments are currently available to evaluate patients with prostate cancer. However, only a few tools are available to assess Korean patients, and therefore we demonstrated a linguistic validation of Korean Expanded Prostate Cancer Index Composite for Clinical Practice (EPIC-CP).

Comprehensive Review of Effective Application of Questionnaires for Clinical Research on Lower Urinary Tract Symptoms With Translation and Cultural Adaptation to the Korean Language.

Lower urinary tract symptoms are highly prevalent and closely related to patients' quality of life. Clinical research on urologic disease is essential for accumulating evidence on patient management; however, the major obstacle is converting patients' subjective symptoms to objective parameters. The optimal application of well-developed and validated questionnaires is vital in achieving objectivity and minimizing bias in clinical research.

Mirabegron for treatment of overactive bladder symptoms in patients with Parkinson's disease: A double-blind, randomized placebo-controlled trial (Parkinson's Disease Overactive bladder Mirabegron, PaDoMi Study).

Aims: This study aimed to investigate the efficacy and safety of mirabegron for Parkinsonism patients with overactive bladder (OAB) symptoms in a randomized, placebo-controlled, multicenter study.

Materials And Methods: Inclusion criteria are Parkinsonism with OAB symptoms for 4 weeks or more, OAB symptom score (OABSS) questionnaire scores greater than 2, and OABSS urgency question scores greater than 1. After a 2-week wash-out period, the patients were randomized into placebo and mirabegron groups at visit 2.

The Current Positioning of Augmentation Enterocystoplasty in the Treatment for Neurogenic Bladder.

Augmentation enterocystoplasty (AEC) is a surgical procedure in which the bladder is enlarged using an intestinal segment in patients with lower urinary tract dysfunction who fail to achieve satisfactory results with all conservative treatments. Currently, surgical materials and procedures, concomitant correction of upper urinary tract abnormalities, or bladder neck reconstruction may vary depending on the experience and preferences of the surgeons. AEC has been proven to be successful with respect to surgical goals, such as achieving urinary continence, improving quality of life, and preserving the upper urinary tract over the long term.

Enucleation of the prostate: An anatomical perspective.

Among transurethral surgery for benign prostatic hyperplasia (BPH), anatomical endoscopic enucleation of the prostate (AEEP) differs from conventional transurethral surgery as it adopts the same enucleation principle as open surgery. AEEP is known as an effective and safe surgical method. However, the learning curve is steep because the surgical anatomy is different from that of conventional transurethral surgery.
