This study aims to ascertain the associations between serum leptin levels and metabolic syndrome and semen parameters in patients with infertility. A total of 200 patients who were diagnosed as primary infertility in our hospital were enrolled in this study, and they were divided into MetS group and non-MetS group. About 30 healthy men were enrolled as the control group.

Prostate cancer (PCa) currently ranks second in male tumor mortality. Targeting immune checkpoint in tumor as immunotherapy is a new direction for tumor treatment. However, targeting PD-1/PD-L1 and CTLA4 to treat PCa has poor immunotherapeutic efficacy because PCa is known as a cold tumor.

Article Synopsis
  • - The study aimed to evaluate the effectiveness of pulsed thulium laser (PTL) combined with triamcinolone injections for treating failed posterior urethral anastomosis (FPUA) in 35 male patients.
  • - Patients underwent either PTL or plasma treatment along with the steroid injection and were monitored for changes in urinary flow and complications over an average follow-up of 21 months.
  • - Results showed that PTL treatment improved urinary flow significantly compared to plasma treatment, suggesting it may provide better short-term results for maintaining urethral patency after FPUA.

Background: Interstitial cystitis/bladder pain syndrome (IC/BPS) is a bladder syndrome of unknown etiology. Reactive oxygen species (ROS) plays a major role in ferroptosis and bladder dysfunction of IC/BPS, while the role of ferroptosis in IC/BPS progression is still unclear. This study aims to investigate the role and mechanism of ROS-induced ferroptosis in IC/BPS using cell and rat model.

Background: Male infertility is a common disease affecting male reproductive health. Leptin is an important hormone that regulates various physiological processes, including reproductive function. However, few experimental studies have been carried out to elucidate the mechanism of leptin's effects on male reproductive function.

Objectives: Our study aimed to elucidate the possible relationship between endogenous circulating testosterone and the beginning and development of stress urinary incontinence (SUI) in postmenopausal women.

Patients And Methods: The clinical data of female patients with SUI who underwent surgery at our hospital from January 2014 to February 2023 and healthy female volunteers recruited during the same period were retrospectively analyzed according to age and body mass index (BMI). Venous blood samples were taken from all subjects, and levels of estradiol, luteinizing hormone, prolactin, follicle-stimulating hormone, progesterone, and testosterone were measured by radioimmunoassay.

Objectives: The aim of this study was to demonstrate the feasibility of a modified sling mid-urethral suspension + subcutaneous tunnel-double point fixation technique for the treatment of male urinary incontinence and to preliminarily evaluate the short-term clinical efficacy of this technique.

Patients And Methods: The clinical data of patients treated with the modified sling mid-urethral suspension + subcutaneous tunnel-double point fixation technique using a Pelvimesh pelvic floor repair patch as a sling were collected. The primary evaluation criteria were surgery-related indicators and daily urinal pad usage before and after treatment, and the secondary evaluation criteria were the corresponding incontinence scores and the results of surgery-related questionnaires.

Background/objective: Serpina3n/Serpina3 has been identified to be implicated in inflammatory diseases, but its role in interstitial cystitis/bladder pain syndrome (IC/BPS) remains unknown. Here, we aimed to reveal serpina3n/serpina3 role in IC/BPS in vivo and in vitro.

Methods: The IC/BPS model in mice was induced by intraperitoneal injection of 150 mg/kg of cyclophosphamide (CYP).

Purpose: Holmium laser enucleation of the prostate (HoLEP) is reported to be widely used in the surgical treatment of benign prostatic hyperplasia (BPH), which consists of two procedures: enucleation and morcellation. This study is to examine the efficiency and safety of two different morcellator systems within a cohort of men undergoing HoLEP for BPH.

Methods: A total of 210 consecutive patients undergoing HoLEP and morcellation procedures were enrolled.

Background: Generally, little is known about prognostic factors in bladder cancer patients under 40 years of age. We therefore performed a retrospective study to identify prognostic factors in these younger bladder cancer patients.

Methods: We collected clinicopathological data on bladder cancer patients ≤40 years old diagnosed between 1975 and 2018 from the Surveillance, Epidemiology, and End Results (SEER) database.

Objective: To evaluate the safety and clinical efficiency of holmium laser enucleation of the prostate (HoLEP) in the treatment of small-volume BPH (SBPH) complicated by severe lower urinary tract symptoms (LUTS).

Methods: We retrospectively analyzed the clinical data on 82 cases of SBPH with severe LUTS treated by HoLEP from January 2017 to December 2018. The patients were aged (65.

The role of high-fat diet (HFD) induced gut microbiota alteration and Ghrelin as well as their correlation in benign prostatic hyperplasia (BPH) were explored in our study. The gut microbiota was analyzed by 16s rRNA sequencing. Ghrelin levels in serum, along with Ghrelin and Ghrelin receptor in prostate tissue of mice and patients with BPH were measured.

To compare the efficacy and safety of plasma kinetic enucleation of the prostate (PKEP) with holmium laser enucleation of the prostate (HoLEP) for treatment of benign prostatic hyperplasia (BPH). A total of 160 patients with indications for the surgical treatment of BPH were randomly assigned to receive either PKEP or HoLEP prospectively. Baseline characteristics, perioperative data, and postoperative outcomes of the patients were recorded.

CD44 is a marker of cancer stem cell (CSC) in many types of tumors. Alternative splicing of its 20 exons generates various CD44 isoforms that have different tissue specific expression and functions, including the CD44 standard isoform (CD44s) encoded by the constant exons and the CD44 variant isoforms (CD44v) with variant exon insertions. Switching between the CD44v and CD44s isoforms plays pivotal roles in tumor progression.

Objective: To investigate the clinical effect of "3+1" bladder function restoration combined with holmium laser enucleation of the prostate (HoLEP) in the treatment of benign prostatic hyperplasia (BPH) with acontractile detrusor (ACD).

Methods: We treated 35 BPH patients with ACD by HoLEP followed by "3+1" bladder function restoration, that is, a 3-phase bladder function training plus simultaneous 1-drug medication after surgery. We recorded and analyzed the detrusor pressure, post-void residual urine volume (PVR), maximum urinary flow rate (Qmax), International Prognostic Scoring System (IPSS) scores, quality of life (QoL), voluntary micturition, satisfaction with the bladder function, hydronephrosis, ureterectasia, renal function, and urinary tract infection of the patients before and after treatment.

To develop a standardized scoring system, the BPH surgical scoring (BPHSS) system, to quantify the ability to predict the perioperative outcomes resulting from an enlarged prostate. There are two parts included in this study: the retrospective observational study (875 patients treated with holmium laser enucleation of the prostate, HoLEP) and the prospective observational study (111 patient underwent HoLEP). All the outcome data included the following: the basic patient preoperative characteristics, operation time (OT), pre- and post- surgery hemoglobin decrease, Na variation, hospital stay duration, duration of bladder irrigation, catheterization time, and hospitalization time.

Article Synopsis
  • The study compares the long-term outcomes of holmium laser enucleation of the prostate (HoLEP) and plasmakinetic resection of the prostate (PKRP) in treating benign prostatic enlargement (BPE).
  • In the assessment of various health metrics, HoLEP patients showed no need for reoperations, while two PKRP patients did, and HoLEP had better results in key measures like flow rate and prostate volume.
  • Overall, both HoLEP and PKRP are effective treatments, but HoLEP presents notable advantages in improving PSA levels, sexual function, and urinary symptoms.
