Comparison of mirabegron and vibegron for clinical efficacy and safety in female patients with overactive bladder: a multicenter prospective randomized crossover trial.

Purpose: To compare the efficacy and safety of mirabegron and vibegron in female OAB patients.

Methods: We conducted a multicenter, prospective, randomized crossover study of female patients with OAB. The patients were assigned to Group MV (mirabegron for 8 weeks, followed by vibegron for 8 weeks) or group VM (vibegron for 8 weeks, followed by mirabegron for 8 weeks).

High-Fat and High-Sucrose Diet Leads to Skeletal Muscle Loss and Bladder Dysfunction in Rat.

Purpose: In this study, we investigated skeletal muscle loss and bladder dysfunction caused by high-fat/high-sucrose (HFS) diet.

Methods: Twelve-week-old Sprague-Dawley (SD) female rats were fed on normal (Group N) or HFS (Group HFS) diet for 12 weeks. We conducted urodynamic investigation and pharmacologic in vitro.

[Pre-Operative Factors Affecting Trifecta Achievement in the Initial Series of Robot-Assisted Partial Nephrectomy].

We investigated pre-operative factors affecting trifecta achievement in robot-assisted partial nephrectomy (RAPN). We retrospectively analyzed 81 patients who underwent RAPN from December 2016 to September 2021 with final malignant pathologies. Trifecta was defined as negative resection margin (RM),warm ischemic time (WIT) less than 25 minutes, and no severe perioperative complications (Clavien-Dindo＜III).

[Comparison of Perioperative Outcomes between Open and Robot-Assisted Laparoscopic Radical Cystectomy].

We compared the perioperative outcomes of open (ORC) and robot-assisted laparoscopic radical cystectomy (RARC) for patients with bladder cancer. We retrospectively investigated the intraoperative and 90-day postoperative complications of ORC and RARC performed from March 2014 to September 2021 based on the medical records. Perioperative complications were categorized according to the Clavien- Dindo classification.

[Treatment Outcome of Ureteral Reconstruction Surgery].

We retrospectively reviewed the surgical outcome of ureteral reconstruction that was performed in Asahikawa Medical University Hospital between 2005 and 2021. A total of 14 patients (3 males, 11 females; 15 ureters) were included in this analysis. The median age was 57 years old.

[Clinical Significance of Preoperative Image Classification Systems in Robot-Assisted Laparoscopic Partial Nephrectomy].

Robot-assisted laparoscopic partial nephrectomy (RAPN) is being used in Japan as a less invasive procedure. RENAL nephrometry (RN) score, Preoperative Aspects and Dimensions Used for an Anatomical (PADUA) Classification and Simplified PADUA Renal (SPARE) nephrometry system are tumor-specific morphometry scoring systems used for predicting the difficulty of partial nephrectomy. Adherent perinephric fat (APF) is one of the patient-specific factors related to the difficulty of partial nephrectomy.

Dutasteride add-on treatment to tadalafil for patients with benign prostatic enlargement is similarly effective as dutasteride add-on treatment to alpha blocker: a propensity-score matching analysis.

Purpose: To investigate the efficacy of dutasteride add-on treatment to tadalafil in patients with lower urinary tract symptoms (LUTS) suggestive of benign prostatic enlargement (BPE).

Methods: A prospective study was conducted in patients with BPE who had not been satisfied with tadalafil monotherapy for more than 3 months. Inclusion criteria were prostate volume (PV) ≥ 30 ml and IPSS ≥ 8 or QOL index ≥ 3 under administration of tadalafil without anticholinergic agent.

Risk factors for failure of long-term dutasteride add-on treatment to alpha-adrenergic antagonist for patients with lower urinary tract symptoms and benign prostatic enlargement.

Purpose: To identify the clinical factors resulting in the failure of dutasteride add-on treatment to alpha-adrenergic antagonist for patients with lower urinary tract symptoms and benign prostatic enlargement (BPE).

Methods: We retrospectively surveyed the patient cohort who had been enrolled in the study of dutasteride add-on treatment to alpha-adrenergic antagonist from December 2009 to November 2011. Treatment failure was defined as receiving surgery for BPE or requiring intermittent catheterization or permanent bladder catheter for urinary retention or huge postvoid residual urine.

Uroflowmetry pattern in detrusor underactivity and bladder outlet obstruction in male patients with lower urinary tract symptoms.

Objectives: To investigate if uroflowmetry (UFM) curve patterns could differentiate between detrusor underactivity (DU) and bladder outlet obstruction (BOO).

Methods: A hundred consecutive data sets of male patients who were evaluated using UFM and invasive urodynamics (pressure flow study) were retrospectively collected. DU and BOO were diagnosed according to the bladder contractility index and BOO index.
