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.

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.

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.

OBJECTIVETo discuss the results and significance of the detection of the CFTR gene mutation in azoospermia patients with congenital unilateral absence of the vas deferens (CUAVD).

METHODSWe collected peripheral blood samples from 6 azoospermia patients with CUAVD for detection of the CFTR gene mutations and single nucleotide polymorphisms. We analyzed the genome sequences of the CFTR gene in comparison with the website of the UCSC Genome Browser on Human Dec. 2013 Assembly.

RESULTSMissense mutation of c. 592G > C in exon 6 was found in 1 of the 6 azoospermia patients with CUAVD and splicing mutation of c. 1210-12T[5] was observed in the noncoding region before exon 10 in 2 of the patients, both with the V470 haplotype in exon 11.

CONCLUSIONMutations of the CFTR gene can be detected in azoospermia patients with CUAVD and the detection of the CFTR gene mutation is necessary for these patients.

OBJECTIVETo summarize the features and treatment of male infertility induced by autosomal dominant polycystic kidney disease (ADPKD), and compare the outcomes of intracytoplasmic sperm injection (ICSI) for infertile men with ADPKD and those with congenital bilateral absence of vas deferens (CBAVD).

METHODSWe retrospectively analyzed 21 cases of ADPKD-induced infertility, 15 treated by ICSI (group A), and another 164 cases of strictly matched CBAVD-induced infertility (group B). We compared the two groups in the couples' age, the number of ICSI oocytes, and the rates of fertilization, transferrable embryos, good embryos, embryos implanted, clinical pregnancy, biochemical pregnancy, early abortion, singleton and twins in the first cycle.

RESULTSAfter 28 cycles of ICSI, 10 of the 15 ADPKD-induced infertility patients achieved clinical pregnancy, including 7 cases of live birth, 1 case of spontaneous abortion, and 2 cases of pregnancy maintenance. No significant differences were observed between groups A and B in the couples' age, the wives' BMI, or the numbers of ICSI oocytes and embryos transplanted (P >0.05), nor in the rates of ICSI fertilization (72.64% vs 76.17%), transferrable embryos (51.28% vs 63.24%), quality embryos (38.46% vs 49.83%), embryo implantation (17.64% vs 38.50%), abortion (0 vs 9.23%), singleton (50% vs 81.54%) and twins (50% vs 18.46%). However, the rates of clinical pregnancy (13.33% vs 42.68%, P = 0.023 <0.05) and biochemical pregnancy (13.33% vs 39.63%, P = 0.032 <0.05) were significantly lower in group A than in B.

CONCLUSIONICSI is effective in the treatment of male infertility induced by either ADPKD or CBAVD, but the ADPKD cases have a lower success rate than the CBAVD cases in an individual cycle. The affected couples should be informed of the necessity of prenatal genetic diagnosis before embryo implantation and the inevitable vertical transmission of genetic problems to the offspring.
