Article Abstract

The decline of estrogen production after menopause is contributing factor to urinary incontinence (UI), and particularly stress urinary incontinence (SUI). We determined the preventive effects of herbal extract mixture (HEM) on UI in ovariectomized Sprague Dawley rats. Female 9-weeks old rats were ovariectomized and treated with HEM (2.2, 11, or 55 mg/kg/day) for 8 weeks. The index of urinary bladder weight to body weight in the HEM and non-ovariectomized and non-treated (SHAM) groups were slightly higher than the ovariectomized, non-treated group (OVX). The contraction index of acetylcholine to KCl on detrusor smooth muscle strips in the HEM groups showed a dose-dependent recovery. HEM treatment also significantly improved collagen levels, as shown by Masson trichrome staining, as well as hydroxyproline levels in the urinary bladder. Serum estradiol levels in the HEM groups were higher than the OVX group. In conclusion, HEM increased estradiol levels in serum and improved factors related to urinary incontinence. The improvements in estradiol levels were related to changes in urinary incontinence.

Background: Excisional hemorrhoidectomy and stapled hemorrhoidopexy are 2 common procedures for treating symptomatic hemorrhoids. However, concerns persist regarding the risk of postoperative complications and their unclear prevalence in the literature. This systematic review aims to evaluate and compare the prevalence of incontinence after stapled hemorrhoidopexy and excisional hemorrhoidectomy.

Objectives: To compare postoperative complication rates of patients with metabolic syndrome (MetS) with patients without MetS after holmium laser enucleation of the prostate (HoLEP) for management of benign prostatic hyperplasia (BPH).

Patients And Methods: We retrospectively reviewed patients aged >40 years who underwent HoLEP at our institution from 2007 to 2022. Criteria for MetS were diagnoses of at least three of the following: diabetes mellitus, hypertension, hyperlipidaemia, or obesity (body mass index ≥30 kg/m).

Introduction: The Retzius-sparing technique for prostate cancer has shown favorable continence recovery outcomes. Magnetic resonance imaging after Retzius-sparing showed that the bladder anterior wall is widely connected to the abdominal wall, which contributes to urinary continence. We aimed to evaluate whether the Peritoneal Fixation technique, which involves suturing the anterior bladder wall onto the abdominal wall above the pubic bone, contributes to the recovery of urinary continence.

Focal therapy (FT) is an emerging option for intermediate-risk prostate cancer (IR-PCa). Transperineal MRI fusion laser ablation of PCa (TPFLA) is a novel FT technique with limited data reported. We conducted a phase I clinical trial evaluating the safety, feasibility, and 1-year oncologic results for patients with IR-PCa treated with TPFLA in an office setting.
