Individuals with congenital absence of the vas deferens (CAVD) may transmit cystic fibrosis (CF)-causing variants of the cystic fibrosis transmembrane conductance regulator ( CFTR ) gene to their offspring through assisted reproductive technology (ART). We aimed to delineate the spectrum and estimate the prevalence of CF-causing variants in Chinese individuals with CAVD through a cohort analysis and meta-analysis. CFTR was sequenced in 145 Chinese individuals with CAVD. CFTR variants were classified as CF-causing or non-CF-causing variants regarding clinical significance. A comprehensive genotype analysis was performed in Chinese individuals with CAVD, incorporating previous studies and our study cohort. The prevalence of CF-causing variants was estimated through meta-analysis. In our cohort, 56 different CFTR variants were identified in 108 (74.5%) patients. Twenty variants were categorized as CF-causing and were detected in 28 (19.3%) patients. A comprehensive genotype analysis of 867 patients identified 174 different CFTR variants. Sixty-four were classified as CF-causing variants, 56.3% of which had not been previously reported in Chinese patients with CF. Meta-analysis showed that 14.8% (95% confidence interval [CI]: 11.0%-18.9%) CAVD cases harbored one CF-causing variant, and 68.6% (95% CI: 65.1%-72.0%) CAVD cases carried at least one CFTR variant. Our study underscores the urgent need for extensive CFTR screening, including sequencing of whole exons and flanking regions and detection of large rearrangements and deep intronic CF-causing variants, in Chinese individuals with CAVD before undergoing ART. The established CF-causing variants spectrum may aid in the development of genetic counseling strategies and preimplantation diagnosis to prevent the birth of a child with CF.

OBJECTIVE:
To assess relationships between cold spells and genitourinary hospitalization risk.
METHODS:
Hospitalization records for genitourinary system diseases (GUDs) from 16 districts in Beijing (2013-2018) were analyzed. Cold spells were defined based on varying intensity thresholds. A two-stage analytical method was employed: first, generalized linear models assessed district-specific associations between cold spells and hospitalizations; second, random-effects meta-analysis aggregated the district-level results. Subgroup analyses were performed by admission type (emergency vs. outpatient), age, and sex.
RESULTS:
A total of 271,579 GUD-related hospitalizations were recorded. Cold spells (p1day2,daily mean temperature below the 1 st percentiles of the daily mean temperature distribution from January 1, 2013, to December 31, 2018, lasting for two or more consecutive days) were linked to a significant rise in hospitalization risks: 1.43 (95% CI: 1.32-1.56) for all GUDs, 1.35 (95% CI: 1.23-1.49) for urinary system diseases, and 1.46 (95% CI: 1.28-1.67) for renal failure, when compared to non-cold spell days. Emergency admissions showed higher risk increases than outpatient admissions.
CONCLUSION
Extreme cold spells significantly elevate hospitalization risks for GUDs. This highlights the urgent need for targeted public health interventions to mitigate cold-related health impacts, especially for vulnerable populations.

Objective:
To explore the diagnosis, classification and treatment of ectopic seminal tract opening in enlarged prostatic utricle (EPU).
METHODS:
We retrospectively analyzed the clinical data on 22 cases of ectopic seminal tract opening in EPU confirmed by spermography, EPU open cannula angiography or intraoperative puncture of the vas deferens and treated by transurethral incision of EPU, cold-knife incision or electric incision of EPU, full drainage of the anteriorwal, and open or laparoscopic surgery from October 1985 to October 2017.
RESULTS:
Five of the patients were diagnosed with ectopic opening of the vas deferens and the other 17 with ectopic opening of the ejaculatory duct in EPU. During the 3-48 months of postoperative follow-up, symptoms disappeared in all the cases, semen quality was improved in those with infertility, and 2 of the infertile patients achieved pregnancy via ICSI.
CONCLUSIONS
Ectopic seminal tract opening in EPU is rare clinically. Spermography is a reliable method for the diagnosis of the disease, and its treatment should be aimed at restoring the smooth flow of semen based on proper classification and typing of the disease.

Mycoplasma genitalium (MG) was first isolated by Tully from the urinary tract of the male patient with non-gonococcal urethritis (NGU) in 1981. MG is extremely difficult to be cultured and was rarely studied until the development and application of molecular biology technology. The research on MG in China is still in the primary stage. However, relevant studies abroad have found that it is an important pathogen causing human genitourinary tract infection and spreading worldwide. Male MG infection is reportedly related to NGU, prostatitis, epididymitis, balanoposthitis, male HIV infection, and male infertility. This review outlines the advances in the studies of MG in male urogenital diseases.

ObjectiveTo explore Mycoplasma genitalium (MG) infection in the urogenital tract of infertile men and its influence on semen quality.
METHODSSemen samples were collected from 352 infertile males in the Center of Reproductive Medicine of Nanjing General Hospital from March to July 2015. MG infection was detected by real-time fluorescence simultaneous amplification and testing and semen analyses were conducted according to the WHO Laboratory Manual for the Examination and Processing of Human Semen (5th Ed) on the semen pH value, semen volume, total sperm count, sperm concentration, total sperm motility, percentages of progressively motile sperm (PMS) and immotile sperm (IMS), and sperm DNA fragmentation index (DFI). The data obtained were subjected to statistical analysis by t-test and non-parametric test (Wilcoxon test).
RESULTSMG infection was found in 3.4% (12/352) of the infertile patients. Compared with the MG-positive cases, the MG-negative ones showed a significantly higher semen volume ([2.85 ± 0.14] vs [3.84 ± 0.12] ml, P = 0.008) and percentage of PMS ([15.86±1.72] vs [60.95 ± 5.63] %, P = 0.032) but a lower DFI ([30.73 ±2.24] vs [20.71 ± 1.55]%, P = 0.014). However, no statistically significant differences were observed between the two groups in the semen pH value (7.38 ±0.02 vs 7.39 ± 0.01, P = 0.774), sperm concentration ([52.96 ± 15.78] vs [60.05 ± 4.29]×10⁶/ml, P = 0.683), sperm count ([154.15 ± 46.37] vs [221.56 ± 15.43]×106, P = 0.236), total sperm motility ([29.04 ± 3.11] vs [33.52 ± 1.51] %, P = 0.626), or percentage of IMS ([23.57 ± 0.99] vs [62.34 ± 1.69] %, P = 0.691).
CONCLUSIONSUrogenital MG infection is common in infertile males and potentially affects the semen quality, especially sperm vitality of the patient.

8.Genitourinary problems in the elderly in geriatric hospitals.
Journal of the Korean Medical Association 2017;60(7):536-541
Population analyses and demographic data have clearly documented the rapid growth of the aging population in recent years. Although the population over 65 currently accounts for approximately 13.2% of the total population in Korea, it is estimated that this number will reach at least 40% by 2060. Aging is associated with a general decline in almost every physiological function of biological systems, including the lower urinary tract. Aging is also known to put individuals at a high risk for urinary tract infections. Geriatric hospitals in Korea have undergone a large expansion in terms of the number of beds and institutions. Many elderly patients in geriatric hospitals suffer from various genitourinary disorders. In particular, voiding dysfunction and urinary tract infections are prevalent comorbidities of other chronic geriatric diseases in patients in geriatric hospitals. Careful monitoring and management can help to reduce those genitourinary problems in elderly patients in geriatric hospitals.

PURPOSE: Penile fracture is rare, but it is a urological emergency that always requires immediate attention. Moreover, penile fracture has been reported more frequently in recent years. It may have devastating physical, functional, and psychological consequences if not properly managed in time. MATERIALS AND METHODS: The objective of this study was to highlight the causes, clinical presentation, and outcomes of cases of penile fracture. This was a prospective observational study extending from November 2012 to November 2014. Each patient underwent a thorough clinical evaluation and received proper treatment. RESULTS: Twenty patients with penile fracture, aged 19 to 56 years (mean, 28 years) were evaluated in this study. Vaginal intercourse was the most common mechanism of injury. Most of the patients (95%) were diagnosed clinically with a proper history and clinical examination. Nineteen patients were treated surgically. The patients underwent six months of follow-up, and were evaluated with local examinations, questionnaires, and colour Doppler ultrasonography as necessary. CONCLUSIONS: Although penile fracture is an under-reported urological emergency, its incidence is increasing. It is usually diagnosed based on a clinical examination, but ultrasonography can be very helpful in diagnosis. Especially in cases where treatment is delayed, surgery is preferable to conservative management, because it is associated with better outcomes and fewer long-term complications.

National Journal of Andrology 2015;21(5):467-471
Fosfomycin (FOM) is an antibiotic with a small relative molecular weight (138.1) and a long half-life, and has a unique chemical structure and antibacterial mechanisms. It exerts a bactericidal activity by inhibiting the early synthesis of bacterial cell walls. It is also a broad-spectrum antibiotic with a good drug tolerance and compliance and a low pressure to bacterial resistance, but no cross-resistance with other antibiotics. Recent studies show the effectiveness of FOM in the treatment of acute uncomplicated urinary tract infections and urogenital tract infections as well, such as prostatitis and epididymitis. This review focuses on the clinical application of FOM in the treatment of infectious diseases of the urogenital tract.
