Screening tool for sarcopenia (SARC-F) predicts unsatisfactory medical treatment of lower urinary tract symptoms in elderly men aged 75 years or older: a preliminary observational study.

We investigated the influence of sarcopenia on treatment outcomes in elderly patients receiving medical therapy for lower urinary tract symptoms (LUTS). We included male patients with LUTS aged ≥ 75 years who had not changed their medication for 1 year. Current conditions were estimated using IPSS, overactive bladder symptoms score (OABSS), and screening tool for sarcopenia (SARC-F).

Validation of the area under the Watts factor curve during the voiding cycle as a novel parameter for diagnosing detrusor underactivity in females.

Objective: Detrusor underactivity (DU) is a common cause of lower urinary tract symptoms (LUTS). To date, no consensus has been reached on the urodynamic criteria for defining DU. We previously proposed the area under the curve of the Watts factor (WF-AUC) as a new parameter for diagnosing DU.

Ischemic priapism caused by self intracavernous injection of tadalafil.

Introduction: We present a case of ischemic priapism caused by self intracavernous injection of tadalafil.

Case Presentation: A 77-year-old man developed priapism due to self-injection of tadalafil into the corpus cavernosum. He presented to our hospital 2 days after the development of priapism and severe penile pain.

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).

[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.
