Pneumovesical vesicovaginal fistula repair: Lessons learned from an initial series of 25 patients.

Objectives: This study aims to share the experiences and outcomes of laparoscopic pneumovesical repair for vesicovaginal fistulas (VVF).

Materials And Methods: A retrospective review of medical records from a single institution over 10 years was conducted. The focus was on patients who underwent VVF repair using a pneumovesical approach with three 5 mm laparoscopic ports.

Cumulative sum analysis of the learning curve for retrograde intrarenal stone surgery in newbie surgeons.

Introduction: This study investigated the learning curve of retrograde intrarenal surgery (RIRS) in patients with medium-sized stones using cumulative sum analysis (CUSUM) to evaluate the competence and proficiency of three new surgeons during their first RIRS procedures.

Materials And Methods: We conducted a retrospective review of 227 patients from 2019 to 2022 at a single institution. The patients were divided into four groups based on the operating surgeon: tutor surgeon (85 patients), newbie surgeon A (21 patients), newbie surgeon B (85 patients), and newbie surgeon C (36 patients).

Can natural killer cell activity help screen patients requiring a biopsy for the diagnosis of prostate cancer?

Purpose: To evaluate the usefulness of natural killer cell activity (NKA) in diagnosing prostate cancer (PC).

Materials And Methods: The medical records of patients who underwent transrectal prostate biopsy (TRBx) at Korea University Ansan Hospital between May 2017 and December 2017 were retrospectively reviewed. NKA levels were measured using NK VueR Tubes (ATgen, Sungnam, Korea).

Preoperative sterile pyuria as a prognostic biomarker for intravesical recurrence in upper urinary tract urothelial carcinoma.

Purpose: To evaluate if preoperative sterile pyuria can be a prognostic factor for intravesical recurrence (IVR) and overall survival (OS)in patients with upper tract urothelial carcinoma (UTUC) undergoing surgery.

Materials And Methods: We retrospectively reviewed the medical records of patients who were diagnosed with UTUC from October 2003 to December 2016 at Korea University Medical Center. Sterile pyuria was defined as urine containing five or more white blood cells per high-power field in the absence of bacteria in urine culture.

Seasonal Variation of Overactive Bladder Symptoms in Female Patients.

Purpose: To evaluate seasonal variations of overactive bladder (OAB) symptoms in women who visited hospital clinics.

Methods: Medical records of female patients treated for OAB symptoms from January 2011 to December 2017 were retrospectively reviewed. Patients with pyuria at the first visit, those who did not complete the questionnaire, and those with <3 overactive bladder symptom scores (OABSS) were excluded.

Is androgen deprivation therapy associated with cerebral infarction in patients with prostate cancer? A Korean nationwide population-based propensity score matching study.

Purpose: Previous studies have suggested that androgen deprivation therapy (ADT) is associated with cerebral infarction. However, conflicting results have been reported by other researchers. The aim of this study was to evaluate the association between ADT and cerebral infarction in patients with prostate cancer (PC) using big data.

Analysis of Present Status for Surgery of Benign Prostatic Hyperplasia in Korea Using Nationwide Healthcare System Data.

Purpose: There are no established statistical data available for the comparison of different surgical methods adopted for the resection of benign prostatic hyperplasia (BPH). This study investigates the present status related to BPH surgery in Korea for the past 8 years.

Methods: National-level data from the National Health Insurance Service and National Statistical Office were analyzed in this study.

α-Blocker and Risk of Dementia in Patients with Benign Prostatic Hyperplasia: A Nationwide Population Based Study Using the National Health Insurance Service Database.

Purpose: A recent study demonstrated that tamsulosin increased the risk of dementia in patients with benign prostatic hyperplasia. However, this study had a number of limitations. We evaluated the association between α-blockers and dementia in patients with benign prostatic hyperplasia.

Selective clamping hand-assisted laparoscopic partial nephrectomy for localized renal tumors: A novel technique.

Purpose: In this study, we described our initial experience and analyze the learning curve of segmental renal artery branch clamping with hand-assisted laparoscopic partial nephrectomy (PN) using special instruments.

Materials And Methods: We conducted a retrospective review of consecutive cases of hand-assisted laparoscopic PN (LPN) between May 2015 and April 2018. Patient demographics, tumor characteristics, perioperative details, postoperative complications, and warm ischemic time for segmental artery branch clamping were included in our analysis.

Electric field control of nonvolatile four-state magnetization at room temperature.

We find the realization of large converse magnetoelectric (ME) effects at room temperature in a magnetoelectric hexaferrite Ba0.52Sr2.48Co2Fe24O41 single crystal, in which rapid change of electric polarization in low magnetic fields (about 5 mT) is coined to a large ME susceptibility of 3200 ps/m.
