Sperm recovery and ICSI outcomes in non-obstructive azoospermia with cryptorchidism treated by orchiopexy: a systematic review and meta-analysis.

The aim of this meta-analysis was to quantify the available data concerning sperm retrieval rate (SRR) subsequent to testicular sperm extraction (TESE) and the clinical pregnancy rate (CPR) and live birth rate (LBR) subsequent to TESE and intracytoplasmic sperm injection (ICSI) in patients with non-obstructive azoospermia with cryptorchidism treated by orchidopexy. Furthermore, the aim was to explore the potential predictors of SRR, CPR and LBR within this population. Extensive searches were conducted in PubMed, Embase, Cochrane and Web of Science databases, and 23 articles were included in the study, with 1496 patients.

Cytotoxicity of nonylphenol on spermatogonial stem cells phosphatidylinositol-3-kinase/protein kinase B/mammalian target of rapamycin pathway.

Background: With continuous advancement of industrial society, environmental pollution has become more and more serious. There has been an increase in infertility caused by environmental factors. Nonylphenol (NP) is a stable degradation product widely used in daily life and production and has been proven to affect male fertility.

Ethanol locks for the prevention of catheter-related bloodstream infection: a meta-analysis of randomized control trials.

Background: Current evidence regarding the efficacy of ethanol locks in preventing catheter-related bloodstream infection (CRBI) is inconclusive.

Methods: Electronic databases, including PubMed, Web of Science, Embase, and the Cochrane Library (until April 2018),were systematically searched for relevant studies. Two reviewers independently screened the retrieved records and identified RCTs that met the inclusion criteria.

Circumcision with "no-flip Shang Ring" and "Dorsal Slit" methods for adult males: a single-centered, prospective, clinical study.

This paper was aimed to compare the clinical effectiveness and safety of adult male circumcision using the Shang Ring™ (SR) with the no-flip technique compared with Dorsal Slit (DS) surgical method. A single-centered, prospective study was conducted at the West China Hospital, where patients were circumcised using the no-flip SR (n = 408) or the DS (n = 94) procedure. The adverse events (AEs) and satisfaction were recorded for both groups, and ring-removal time and percentage of delayed removals were recorded for the SR group.

[Radical prostatectomy and radiation therapy for high-risk prostate cancer: An update].

Recently, the D'Amico classification system is widely used for the risk stratification of prostate cancer (PCa) , although no consensus has been reached for the definition of high-risk PCa. This system defines high-risk PCa as a prostate-specific antigen (PSA) level > 20 ng/ml, a Gleason score of 8-10, or a clinical stage ≥ T2c. Because high-risk PCa is prone to recurrence and metastasis after treatment, a proper initial therapy plays a crucial role.

Circumcision Status and Risk of HIV Acquisition during Heterosexual Intercourse for Both Males and Females: A Meta-Analysis.

In this study, we evaluated if male circumcision was associated with lower HIV acquisition for HIV (-) males and HIV (-) females during normal sexual behavior. We performed a systematic literature search of PubMed, EMBASE, and Cochrane Central Register of Controlled Trials (CENTRAL) databases to identify studies that compared HIV acquisition for the circumcised and uncircumcised groups. The reference lists of the included and excluded studies were also screened.

Androgen-deprivation therapy alone versus combined with radiation therapy or chemotherapy for nonlocalized prostate cancer: a systematic review and meta-analysis.

In this paper, we reviewed the long-term survival outcomes, safety, and quality-of-life of androgen-deprivation therapy (ADT) alone versus combined with radiation therapy (RT) or chemotherapy for locally advanced and metastatic prostate cancer (PCa). A literature search was performed using OvidSP. Randomized controlled trials (RCTs) that met the following criteria were included: including locally advanced or metastatic PCa, comparing ADT alone versus combined with any treatment method and reporting quantitative data of disease control or survival outcomes.

Retroperitoneal laparoscopic management method of Castleman's disease in the adrenal gland: two cases report and review of the literature.

Purpose: Castleman's disease (CD) is a rare and complex disease of lymphoid tissues typically involving a mediastinal mass. CD in the adrenal area is an even rarer occurrence. In the present study, two extremely rare cases of adrenal Castleman's disease at our hospital are reported, and the relevant literatures were reviewed.

[No-flip method versus external method for Shang Ring circumcision: a meta-analysis].

Objective: To compare the effect and safety of the no-flip method versus the external method in Shang Ring circumcision.

Methods: We searched relevant randomized controlled trials published in China and abroad comparing the no-flip method and external method of Shang Ring circumcision. Based on the Cochrane Handbook for systematic review, two reviewers independently eval- uated the quality of the included studies and abstracted relevant data, followed by a meta-analysis using the statistical software Review Manager 5.

[Evaluation of greenlight photoselective vaporization of prostate and plasmakinetic resection of prostate for the treatment of eldly benign prostatic hyperplasia men with high surgical risk: a prospective randomised control trial].

Objective: To compare the clinical effects and safety between greenlight photoselective vaporization of prostate (PVP) and plasmakinetic resection of prostate (PRP) in eldly benign prostatic hyperplasia (BPH) men with high surgical risk. METHODS; Fifty three eldly BPH patients, who had the indication of surgical treatment but complicated with at least one internal disease, were randomly divided into PVP group and PRP group. The clinical data of all the patients were collected and compared between the two groups, including pre-operative and post-operative international prostate symptom score (IPSS), postvoid residual urine (PVR), urine flow rate (Qmax), quality of life (QOL) as well as prostate volume (PV), operational time, operative bleeding volume, postoperative recovery, peri-operative complications.

[Circumcision with no-flip Shang Ring technique for adult males: analysis of 168 cases].

Objective: To observe the clinical effects of the no-flip procedure with the Chinese Shang Ring when circumcising adult males with redundant prepuce or phimosis, and to discuss its advantages and disadvantages.

Methods: Using the no-flip Shang Ring technique, we performed circumcision for 167 adult males aged 18 -72 (mean 27.8) years with redundant prepuce or phimosis, and analyzed the clinical data, including the operation time, postoperative complications, ring-removal time, and postoperative appearance of the penis.
