The International Consultation on Incontinence Questionnaire Short Form as a Substitute for 1-Hour Pad Weight Testing in the Evaluation of Urinary Incontinence in Patients With Pelvic Organ Prolapse Undergoing Surgery.

Purpose: Stress urinary incontinence is a postoperative complication occurring in patients with pelvic organ prolapse (POP). Although the 1-hour pad test measures the degree of urinary incontinence qualitatively and quantitatively, some elderly women undergoing POP surgery do not have the daily activities of living to perform the pad test. Therefore, we examined whether the International Consultation on Incontinence Questionnaire Short Form (ICIQ-SF) could be used as an alternative tool for pad tests.

Validation Study of the LSE Classification and Scoring System in Comparison With U-Score.

Objective: To validate the value of the LSE classification and scoring system in predicting surgical outcomes for male anterior urethral stricture cases.

Methods: A retrospective review was conducted on 566 patients who underwent urethroplasty between August 2004 and March 2022. After excluding pelvic fracture urethral injury and non-stricture diseases and incomplete data, 358 patients were classified according to the LSE classification system, and both U score and LSE score were calculated.

Clinical questions in the Japanese Urological Association's 2024 clinical practice guidelines for urethral strictures.

Transurethral procedures such as direct vision internal urethrotomy and urethral dilation have been the traditional treatments for urethral strictures. However, transurethral procedures are associated with high recurrence rates, resulting in many uncured cases and prompting major international urological societies to recommend urethroplasty as the standard treatment owing to its high success rate. In contrast, many Japanese general urologists have little doubts about treating urethral strictures with transurethral treatment.

High frequency of concomitant squamous metaplasia in bulbar urethral stricture and its association with reconstructive delay and urethral rest.

Purpose: To determine the prevalence of concomitant squamous metaplasia (SM), the initial histological change from normal urethra to urethral stricture, in bulbar urethral strictures and to investigate the associated clinical factors.

Methods: A retrospective review was conducted on 165 male patients with bulbar urethral strictures who underwent excision and primary anastomosis (EPA) between 2010 and 2020, for whom complete clinical data and excised urethral specimens were available. An experienced pathologist histologically evaluated concomitant SM in paraffin sections of the proximal end of the excised urethra blinded to the clinical data.

Efficacy of Transvaginal Surgery Using an ORIHIME Mesh With Wider Arms and Adjusted Length.

Introduction: Transvaginal mesh surgery (TVM) is an effective treatment measure for pelvic organ prolapse (POP). However, the ORIHIME mesh (Kono Seisakusho, Japan, Tokyo), which has the disadvantage of poor adherence to tissues, is currently the only product available for this procedure. Our research team has previously developed a modified ORIHIME mesh with wider arms with the aim of minimizing the risk of POP recurrence.

Urosymphyseal fistula development following treatment for radiation-induced urethral stenosis in three patients with prostate cancer.

Introduction: Urosymphyseal fistula is a rare and devastating complication that develops after radiation therapy for prostate cancer and is often triggered by the treatment of radiation-induced urethral stenosis. Here, we report our experience with urosymphyseal fistulas in three patients with prostate cancer.

Case Presentation: Three patients with prostate cancer developed urethral stenosis after radiotherapy.

Favorable Postoperative Outcomes After Transvaginal Mesh Surgery Using a Wide-Arm ORIHIME® Mesh.

Introduction Transvaginal mesh surgery (TVM) is an effective treatment option for pelvic organ prolapse (POP). Although ORIHIME®, the only available mesh product, is thin, soft, and easy to handle, it has the disadvantages of sliding off or mildly adhering to the surrounding tissues. The current study compared the efficacy of using wide-arm ORIHIME (Kono Seisakusho, Japan, Tokyo), non-wide arm ORIHIME, Gynemesh PS (Johnson and Johnson, Japan, Tokyo), and Polyform (Boston Scientific Japan, Japan, Tokyo) meshes for TVM.

Development of a risk assessment method for the detailed consideration of the effects of liquid toxic substance leakage incidents on the human body: ethanol as a model substance.

To ensure safety in chemical plants handling a wide variety of liquid and gaseous hazardous substances, it is necessary to carry out highly accurate risk assessments and take appropriate measures. In this study, a risk assessment method was developed for the problem of the leakage of liquid hazardous substances. The risk assessment of toxic liquid leaks must consider the exposure of workers to the liquid and toxic gases produced by vaporization.

The Japanese Urological Association's clinical practice guidelines for urotrauma 2023.

The Japanese Urological Association's guidelines for the treatment of renal trauma were published in 2016. In conjunction with its revision, herein, we present the new guidelines for overall urotrauma. Its purpose is to provide standard diagnostic and treatment recommendations for urotrauma, including iatrogenic trauma, to preserve organ function and minimize complications and fatality.

Simulation-based risk assessment for the leakage of toxic substances in a chemical plant and the effects on the human body: ethanol as a working model.

Chemical plants must handle a wide variety of hazardous substances. To ensure safety in such plants, it is necessary to conduct extensive and highly accurate risk assessments. In this study, we aimed at developing a method that enables flexible and accurate risk assessment.

[PENILE STRANGULATION CAUSED BY A METALLIC RING SUCCESSFULLY TREATED BY PENILE PUNCTURE PLUS BLOOD REMOVAL INSTEAD OF DESTROYING THE RING].

A 63-year-old man visited our hospital with a complaint of penile swelling caused by metallic ring entrapment in the penis. He had put the ring around his penis 4 hours prior and was subsequently unable to remove it. We attempted to remove the ring using a ring cutter but that was unsuccessful.

Myofibroblast-dominant proliferation associated with severe fibrosis in bulbar urethral strictures.

Objectives: Myofibroblast-dominant proliferation (relative to fibroblast proliferation) is the key process in urethral fibrosis, but its association with clinical features is not understood. We conducted a histological analysis of urethral strictures and examined the association between myofibroblast proliferation and stricture characteristics.

Methods: Formalin-fixed, paraffin-embedded urethral sections sliced axially from 175 male patients with bulbar urethral strictures were retrospectively analyzed.

Transperineal bulbovesical anastomosis for extensive posterior urethral stenoses after treatment of prostatic disease.

Objectives: We report our surgical experience of transperineal bulbovesical anastomosis (BVA) for extensive posterior urethral stenosis (PUS).

Methods: Six male patients who had extensive PUS extending from the bulbomembranous urethra to the bladder neck due to prostatic disease treatment and underwent transperineal BVA between 2014 and 2020 were retrospectively reviewed. BVA was performed according to the elaborate perineal approach for pelvic fracture urethral repair with minor modifications.

A case of traumatic urethral stricture complicated by periurethral abscess while awaiting delayed urethroplasty.

Introduction: We report a case of bulbar urethral injury complicated by periurethral abscess due to inappropriate suprapubic catheter management.

Case Presentation: A 58-year-old man with bulbar urethral injury due to perineal trauma was referred to our hospital, and a suprapubic catheter was inserted for initial management. Although he was instructed to connect the catheter to the urine collection bag, he connected a plug to the catheter.

Objectives: We report our experience with urethral reconstruction for hypospadias surgery-related urethral stricture in terms of surgical and patient-reported outcomes.

Methods: Twenty-nine adult males who underwent urethral reconstruction for hypospadias surgery-related urethral stricture between August 2008 and January 2022 were retrospectively reviewed. Uroflowmetry and patient-reported outcomes were evaluated at 3, 6, and 12 months, and annually thereafter.

Urethral reconstruction for iatrogenic urethral stricture after transurethral prostate surgery: An analysis of surgical and patient-reported outcomes.

Objectives: We investigated the efficacy of urethral reconstruction in male patients with iatrogenic urethral stricture after transurethral prostate surgery.

Methods: We retrospectively reviewed the cases of 82 patients who underwent urethral reconstruction for iatrogenic urethral stricture caused by transurethral prostate surgery between August 2011 and July 2021. Patients were followed up postoperatively with uroflowmetry, postvoid residual urine measurement, and questionnaires using Peeling's picture score, International Prostate Symptom Score, International Consultation on Incontinence Questionnaire Short Form, Sexual Health Inventory for Men, EuroQol-5 dimensions, and EuroQol-5 dimensions visual analog scores.

Surgical and Patient-Reported Outcomes of Delayed Anastomotic Urethroplasty for Male Pelvic Fracture Urethral Injury at a Japanese Referral Center.

We aimed to assess the surgical and patient-reported outcomes of delayed anastomotic urethroplasty (DAU) for pelvic fracture urethral injury (PFUI). We included 211 male patients who underwent DAU for PFUI. DAU success was considered when the urethral lumen was sufficiently large for the passage of a flexible cystoscope, without additional treatment required.

[ARTIFICIAL URINARY SPHINCTER IMPLANTATION AFTER ILEAL NEOBLADDER RECONSTRUCTION: A CASE REPORT].

A 62-year-old man was referred to our department for artificial urinary sphincter (AUS) implantation as treatment for total incontinence after laparoscopic radical prostatectomy. Preoperative cystoscopy revealed bladder tumor that was proven to be high-grade micropapillary urothelial carcinoma by transurethral resection. We performed radical cystectomy with ileal neobladder reconstruction, followed by AUS implantation to treat incontinence.

Role of magnetic resonance imaging in the management of male pelvic fracture urethral injury.

The management of male pelvic fracture urethral injury remains a urological challenge. Pelvic fracture urethral injury can be associated with sequelae, such as urethral gap, erectile dysfunction and urinary incontinence. Delayed anastomotic urethroplasty, the gold standard treatment for urethral gaps caused by pelvic fracture urethral injuries, is technically demanding, and reconstructive urologists should preoperatively obtain as much detailed anatomical information as possible.
