Integrated treatment combining TCM and Western medicine has seen both broad and in-depth development, with formidable status in the field of modern andrology in China. This article attempts to demonstrate the unique advantage of integrated treatment in the therapy of andropathies through a review of the ancient literature on andrology in the field of TCM and on the integrative treatment of prostatic diseases, sexual dysfunction, male infertility and late-onset hypogonadism. There is a need for the advancement of a medical theory that integrates TCM and Western medicine practices to create a new therapeutic system with standardized therapeutic and evaluative protocols for diseases involving male sexual health.展开更多

AI uses machine learning algorithms to predict the success of therapeutic procedures or assist the clinician in the decision-making process. To date, machine learning studies in the andrological field have mainly focused on prostate cancer imaging and management. However, an increasing number of studies are documenting the use of AI to assist clinicians in decision-making and patient management in andrological diseases such as varicocele or sexual dysfunction. Additionally, machine learning applications are being employed to enhance success rates in assisted reproductive techniques (ARTs). This article offers the clinicians as well as the researchers with a brief overview of the current use of AI in andrology, highlighting the current state-of-the-art scientific evidence, the direction in which the research is going, and the strengths and limitations of this approach.展开更多

Although embryonic stem cells （BSC） have greater differentiation potential than adult stem cells, the former is lagging in reaching clinical applications because of ethical concerns and governmental restrictions. Bone marrow stem cells （BMSC） are the best-studied adult stem cells （ASC） and have the potential to treat a wide variety of diseases, including erectile dysfunction （ED） and male infertility. More recently discovered adipose tissuederived stem cells （ADSC） are virtually identical to bone marrow stem cells in differentiation and therapeutic potential, but are easier and safer to obtain, can be harvested in larger quantities, and have the associated benefit of reducing obesity. Therefore, ADSC appear to be a better choice for future clinical applications. We have previously shown that ESC could restore the erectile function of neurogenic ED in rats, and we now have evidence that ADSC could do so as well. We are also investigating whether ADSC can differentiate into Leydig, Sertoli and male germ cells. The eventual goal is to use ADSC to treat male infertility and testosterone deficiency. （Asian JAndrol 2008 Mar; 10： 171-175）展开更多

The introduction of biochemicaltests into the analysis of male factor has the advantage that standardized assays with a coefficient of variationcharacteristic of clinical chemistry are performed, in contrast to biological test systems with a large variability.Biochemical parameters may be used in clinical practice to evaluate the sperm fertilizing capacity (acrosin, aniline blue,ROS), to characterize male accessory sex gland secretions (fructose, α-glucosidase, PSA), and to identify men withsilent genital tract inflammation (elastase, C'3 complement component, coeruloplasmin, IgA, IgG, ROS).展开更多

Thus, the analysis of DNA methylation of specific genes in spermatozoa has the potential to become a new valuable diagnostic marker in clinical andrology. This perspective article discusses the current state and value of DNA methylation analysis in the diagnostic setup of infertile men and outlines challenges and perspectives. It highlights the potential of DNA methylation in andrological diagnostics and its putative benefit in the examination of hitherto idiopathic infertile patients is described.展开更多

Though it is highly prevalent in men with infertility, still it marks its presence in males who do have normal fertility. Determining which patients are negatively affected by varicocele would enable clinicians to better select those men who benefitted the most from surgery. Since conventional semen analysis has been limited in its ability to evaluate the negative effects of varicocele on fertility, a multitude of specialized laboratory tests have emerged. In this review, we examine the role and significance of specialized sperm function tests with regards to varicocele. Among the various tests, analysis of sperm DNA fragmentation and measurements of oxidative stress markers provide an independent measure of fertility in men with varicocele. These diagnostic modalities have both diagnostic and prognostic information complementary to, but distinct from conventional sperm parameters. Test results can guide management and aid in monitoring intervention outcomes. Proteomics, metabolomics, and genomics are areas; though still developing, holding promise to revolutionize our understanding of reproductive physiology, including varicocele.展开更多

Patients and Methods: It was a retrospective study of patients referred with urologic complications following obstetric and gynaecological surgeries. The study took place at the Teaching Clinic of Urology Andrology at CNHU of Cotonou between April 1, 2008 and March 31, 2013. Results: Forty-one patients were studied. They represented 3.5% of people hospitalized at CUUA throughout the study period. The average age was 41 years swith range of 20 and 57 years. Twenty-one (51.2%) of them were married. Thirty patients (73.2%) were referred from a non-academichospital, while 7 patients (17.1%) were referred from academic hospital. Caesarean section was the primary gynecological surgery in 22 cases (53.7%) and hysterectomy in 19 cases (46.3%). Clinically, the pre- dominant symptoms were leakage of urine throughout the vagina and obstructive anuria with or without back pain. We found 31 cases of VVF, 5 cases of bilateral ligation of the ureters, 3 cases of unilateral ligation of the ureter, 1 ureteralinjury and 1 uretero-vaginal fistula. These complications were diagnosed postoperatively in 95.1% of cases. Surgeries done included VVF repair in 31 cases (75.6%), unilateral ureteral reimplantation in 4 cases (9.8%), removal of ligation of the ureters in 3 cases (7.3%), bilateral ureteral reimplantation for 2 cases (4.9%) and end-to-end anastomosisin 1 case (2.4%). The postoperative period was uneventful in 29 cases and we observed 7 cases of surgical site infection. The overall success rate was 87.8%. Conclusion: Urological complications following gynecologic surgeries managed at the urologic department of teaching hospital of Coto-nou had an even higher incidence. Early diagnosis especially during the operative procedure would save the patients’ serious complications and open surgery due to the lack of endo-urological facilities. The most important factor in prevention is good knowledge of pelvicanatomy and good knowledge of the surgical techniques of caesarean operation section and trans-abdominal hysterectomy.展开更多

Its indication is widespread since the first description in 1971 by Sachse. The objective was to analyze the results of EIU in the treatment of urethral stenosis (US) at the Andro-Urology Department of the UHC of Conakry. <strong>Methodology:</strong> It is a prospective descriptive study, lasting 18 months (January 2016-30 June 2017). It involved 102 patients. The variables were: age, etiology of US, type of catheter, duration of catheter wear and recurrences. After a 12-month follow-up, our results were considered good in the absence of recurrences. <strong>Results:</strong> The average age was 54.25 years with the extremes comprising between 16 and 96 years. The main reasons for medical checkup were chronic urine retention at 58.82%. Etiology infection was the most frequent with a ratio of 81.37%, while <em>Escherichia coli</em> was found at 51.29%. US was bulbar (71.57%), unique (67.64%) and less than 1 cm (60.78%). Surgical complication occurred with 9 patients (8.82%) with urethrorrhagia and the external genital organs infiltration in 4 cases. Results were good for 77 patients (75.49%). Stenosis post infection, long and multiple stenoses, urethral catheterization with latex catheter and urethral catheterization of more than 4 days were strongly associated with the recurrence occurrence. <strong>Conclusion:</strong> The EIU is a minimally invasive surgical technique that offers good results.展开更多

The aim of the study was to evaluate the indication and results of EIU in the treatment of stenosis of the male urethra in the Urology-Andrology Department of Kara Teaching Hospital. Methodology: This was a cross-sectional descriptive study with retrospective data collection in the Urology-Andrology department of Kara Teaching Hospital. It involved 21 records of patients with urethral stenosis treated by endoscopic internal urethrotomy (EIU) in the said department during the period from January 2021 to September 2023. The following variables were evaluated: age, circumstance of discovery, site, length, number, etiology of the urethral stenosis and evolution of the patients. Results: The mean age of the patients was 59.2 ± 11.7 years. Infectious etiology of stenosis was predominant with 10 patients (47.6%) followed by trauma with 5 cases (23.8%). The bulbar urethra was the most frequently observed site, with 11 cases (52.4%). The length was mostly less than 2 cm in 12 patients (57.1%). Stenosis was unique in 14 patients (66.7%). The mean postoperative follow-up time was 3.2 months. The result was immediately better in 11 patients (52.4%) and it was poor in 8 patients (38.1%) who required maintenance dilation sessions.展开更多

Stenosis post infection, long and multiple stenoses, urethral catheterization with latex catheter and urethral catheterization of more than 4 days were strongly associated with the recurrence occurrence. <strong>Conclusion:</strong> The EIU is a minimally invasive surgical technique that offers good results.
文摘Introduction: Endoscopic internal urethrotomy (EIU) is a method for stricture opening using transurethral incision by direct visualisation of the urethral channel, resulting in a widening of the urinary canal with the aim of improving the quality of bladder emptying. The aim of the study was to evaluate the indication and results of EIU in the treatment of stenosis of the male urethra in the Urology-Andrology Department of Kara Teaching Hospital. Methodology: This was a cross-sectional descriptive study with retrospective data collection in the Urology-Andrology department of Kara Teaching Hospital. It involved 21 records of patients with urethral stenosis treated by endoscopic internal urethrotomy (EIU) in the said department during the period from January 2021 to September 2023. The following variables were evaluated: age, circumstance of discovery, site, length, number, etiology of the urethral stenosis and evolution of the patients. Results: The mean age of the patients was 59.2 ± 11.7 years. Infectious etiology of stenosis was predominant with 10 patients (47.6%) followed by trauma with 5 cases (23.8%). The bulbar urethra was the most frequently observed site, with 11 cases (52.4%). The length was mostly less than 2 cm in 12 patients (57.1%). Stenosis was unique in 14 patients (66.7%). The mean postoperative follow-up time was 3.2 months. The result was immediately better in 11 patients (52.4%) and it was poor in 8 patients (38.1%) who required maintenance dilation sessions.
