Contexte et objectifs. La sonde double J est très utilisée de nos jours dans le drainage des urines du haut appareil. L'objectif de la présente étude était de décrire le devenir de la pose de la sonde double J. Méthodes. Il s'est agi d'une étude documentaire d'une série des cas ayant bénéficié d'un drainage urinaire du haut appareil par une sonde double J au Centre National Hospitalo-Universitaire Hubert Koutoukou Maga de Cotonou, Bénin ; entre les 1er avril 2018 et 31 mars 2021. Résultats. Les dossiers de cent trois patients (âge moyen 48,4 ans, sexe masculin, 58,3 %) ont été colligés. La pose de la sonde double J représentait 84,74 %. La pose de la sonde double J était unilatérale dans 76,7 % des cas avec une prédominance à droite (56,0 %). L'abord par voie endoscopique pour la pose de la sonde double J était la plus pratiquée (89,3 %). La pose de la sonde double J a été effectuée sans guidage fluoroscopique (à l'aveugle) dans 73,7 % et la durée moyenne du port de cette sonde était 118,37 jours. La fonction rénale était perturbée avec un débit de filtration glomérulaire < 60 ml/minute/1,75 m2 chez 33,0 % des patients. Les étiologies à la base d'une obstruction étaient dominées par la pathologie lithiasique (63,1 %). Le taux de réussite de la sonde double J était de 77,6 %. Les échecs de la sonde double J étaient dus aux pathologies tumorales dans 15,53 %. La durée moyenne d'hospitalisation après la pose de la sonde double J par voie endoscopique était de 7,72 jours. Conclusion. Le syndrome obstructif surtout d'origine lithiasique reste la plus importante indication de l'usage de la sonde double J. Sa réalisation sans guidage fluoroscopique (à l'aveugle) est possible dans le milieu ne disposant pas d'amplificateur de brillance.

Application of transurethral seminal vesiculoscopy in uroandrology / 中华男科学杂志

With the continuous improvement of living conditions, increasing attention is being drawn to the genitourinary health of males, which has boomed the development of uroandrology in recent years. Refractory hemospermia, infertility, and perineal pain are commonly seen in some male patients, and mainly relied on medical imaging for diagnosis in the past, which, however, has a high pseudopositive rate and cannot give an etiological explanation. Patients with these diseases often adopt conservative treatments such as medication and physiotherapy, often with poor prognosis, and those suffering frequent recurrence used to be treated by transurethral resection, laparoscopic surgery or open surgery, which are now rarely employed due to their high rate of postoperative complications, slow recovery, and easy recurrence. In recent years, transurethral seminal vesiculoscopy has gained a wide application in the diagnosis and treatment of the above-mentioned uroandrological diseases and shown its advantages of high clinical effectiveness and low incidence of complications. The review updates on the indications, methods, skills and clinical application of transurethral seminal vesiculoscopy.

Current Situation and Reconsideration on the Study of Integrated Chinese and Western Medicine Andrology / 中国结合医学杂志

The development of Chinese medicine and Western medicine andrology is based on different social background and academic systems, either Chinese medicine or Western medicine andrology has their limitations, therefore, integration of Chinese and Western medicine (ICWM) andrology is in a great need. After more than 30 years of development, andrology has made great achievements in the construction of specialized academic association, holding academic conferences and publication of academic monographs, and the research progress on this field is mainly in the combination of disease and syndrome, microdifferentiation of symptoms and signs and basic research development. However, the comprehensive theoretic system of ICWM andrology has not yet established, and the related studies are still on the primary stage. In the future studies, great efforts still need to be made to expand the methods for the investigation of ICWM, and make innovations in the field of andrology.

Review of Guidelines for the Evaluation and Treatment of Leukocytospermia in Male Infertility

Leukocytospermia is an ill-defined and poorly understood condition affecting up to 30% of male factor infertility. Current guidelines on leukocytospermia vary significantly, although it has been linked to increased rates of infertility, uncertainty about its clinical significance, diagnosis, and treatment remains. The guidelines are conflicting with sparse data scattered across different specialties and continents. This study aims to compare and contrast available international guidelines and recommendations. In addition to these guidelines, we sought to consolidate the findings of trials over the last several decades. English language articles on human observational studies, retrospective, prospective, clinical trials and randomized control trials were searched for using the following terms: “leukocytospermia, pyospermia, and male infertility.” Articles about treatment and management of leukocytospermia that were published between January 2010 and April 2018 were included, as well as four articles referenced in best practice and guideline statements from urological and andrological associations. Disagreements on this topic are highlighted as some guidelines describe no correlation between leukocytospermia and infertility while others show that treatment leads to improvement of sperm quality by many measures including improved pregnancy rate. Various treatments have been suggested including antibiotics, anti-inflammatory medications, and frequent ejaculation. There is a need for definitive characterization of Leukocytospermia as an infectious or inflammatory marker and a re-evaluation of the leukocyte concentration threshold. Additional studies investigating rates of conception as a measure of outcome are needed, to provide greater level of evidence and generalizability of leukocytopsermia management.

Análisis de parámetros seminales en varones subfértiles sin y con varicocele (Pre-Postquirúrgico) / Analysis of seminal parameters in subfertile males without and with varicocele (Pre-Surgical)

Introducción: Durante años, el varicocele se ha propugnado como la causa más común de infertilidad, siendo esta patología la de mayor incidencia en los varones como factor causal (19 - 41%). Material y Métodos: Se evaluaron 228 pacientes, sexo masculino (18 y 39 años) con subfertilidad primaria con o sin varicocele. Se realizó historia clínica, examen físico, laboratorio y espermograma por duplicado. Se dividieron un grupo de 120 pacientes con subfertilidad primaria, varicocele izquierdo y por lo menos un parámetro seminal alterado en dos muestras sometidos a varicocelectomía y control seminal 6 y 9 meses post-operatorio y otro grupo 108 pacientes de iguales características pero sin varicocele. Se utilizaron criterios OMS en concentración, motilidad y morfología espermática. Estudio de casos y controles. Resultados: La mejoría en la concentración de espermatozoides tras el tratamiento quirúrgico fue de 20,06% (p‹ 0,0001) a los 6 meses y 26,31% (p‹ 0,0001) a los 9 meses. La motilidad aumentó 21,32% (p‹ 0,001) a los 6 meses y 28,28% (p‹ 0,0001) a los 9 meses y la morfología mejoró un 26,8% (p‹ 0,0001) a los 6 meses y 57,38% (p‹ 0,0001) a los 9 meses. Todas las variables resultaron estadísticamente significativas tras el tratamiento quirúrgico. No hubo diferencia estadísticamente significativa en ninguna de las variables entre el grupo pre-quirúrgico y el grupo control, y si las hubo en todas las variables estudiadas entre el grupo control comparado con el post- quirúrgico, a favor de este último. Los porcentajes de mejoras entre el grupo post-quirúrgico a los 6 meses y 9 meses de la cirugía, a favor de este último fueron 7,5% (p‹ 0,0001) en la concentración, 5,28 % (p‹ 0.0001) en la motilidad y 25,32% (p‹ 0.0001) en la morfología... Conclusiones: Los parámetros seminales evidenciaron cambios positivos luego de la varicocelectomia y más aún con el transcurrir del tiempo.

Introduction: Varicocele has been proposed for years as the most common cause of infertility, and this condition is the prevalent incidence as causal factor. (19-41%) Material and methods: 228 male patients (between 18 and 39 years old) were evaluated with primary sub fertility with or without varicocele. The records included history, physical examination and two spermogram for patient. The population was divided in two groups. The first one of 120 patients with primary subfertility, left varicocele and at least one abnormal seminal parameter in two samples, with surgical resection of varicocele and final seminal post-surgical evaluation at 6 and 9 months. The other group included 108 patients with similar characteristics but without varicocele. The WHO criteria for spermatic concentration, motility and morphology were applied. Evaluation of cases and controls. Results: The improvement in spermatozoa concentration after treatment was of 20.06% (p<0,0001). The motility improved 21,32% at 6 months (p<0,0001) and 28,28% at 9 months (p<0,0001).The morphology improved 26,8% at 6 months (p<0,0001) and 57,38% at 9 months (p<0,0001)All the parameters were statistically significant after surgery. While there were no significant differences in any parameter between the pre-surgical group and the control group, there were differences in all the parameters evaluated between the control group and the post-surgical group, with best results in the latter.The percentages of improvement in the post-surgical group were 7,5%(p < 0,0001) in concentration, 5,28% in motility and 25,32% in morphology...Conclusions: The seminal parameters showed positive changes after varicocelectomy, especially over time.

Disease-syndrome combination in integrated traditional Chinese and Western medicine in andrology: Confusions and countermeasures in studies / 中华男科学杂志

Researches on the mechanisms underlying the therapeutic effects of the disease-syndrome combination approach in integrated traditional Chinese and Western medicine are becoming a hot spot in andrology, but many recent studies of this kind have failed to explain the connotation of integrated traditional Chinese and Western medicine in andrology. Related existing problems include repeated researches into the same indexes of action mechanisms of different therapeutic principles of traditional Chinese medicine (TCM), Chinese herbal compound and special prescriptions, studies focusing on individual diseases but ignoring symptoms, immature syndrome models for studies of mechanisms, and too much attention to uncertain or immature target mechanisms. The stress should be placed on the action mechanisms of Chinese herbal compound and special prescriptions on male diseases and, what is more important, on the clarification of the essential principles of differentiation and treatment of TCM syndromes. In the recent years, proteomics, genomics, transcriptomics and metabolomics have shed some light upon researches into the mechanisms underlying the therapeutic effects of the disease-syndrome combination approach in integrated traditional Chinese and Western medicine in andrology. An insight into the TCM syndrome, a macroscopic inductive analysis, and a comprehension of such microcosmic aspects as the gene, protein, metabolism and metagenome may contribute to some breakthroughs and new ideas in the studies of disease-syndrome combination in integrated traditional Chinese and Western medicine in andrology.

RNA simultaneous and amplification testing versus the culture method for detecting Ureaplasma urealyticum infection / 中华男科学杂志

Objective@#To investigate the value of real-time RNA simultaneous amplification and testing (SAT) in the detection of Ureaplasma urealyticum (UU) in the semen of infertile males and its clinical significance.@*METHODS@#We collected semen samples from 542 infertility patients and 120 normal fertile men as controls in the Andrology Clinic of Nanjing General Hospital from March to September 2015. We detected UU infection in the samples using the culture method and SAT technology, respectively.@*RESULTS@#All the UU positive cases (except 4 false positive cases) detected by the culture method were also shown to be positive in SAT. The UU detection rate of SAT was significantly higher than that of the culture method both in the infertility patients (54.1 vs 19.7%, P<0.05) and in the normal controls (42.5 vs 12.5%, P<0.05).@*CONCLUSIONS@#SAT is a rapid and accurate method for detecting UU infection in semen samples, with a higher sensitivity and accuracy than the culture method, and it can also be used to evaluate the therapeutic effects. However, the culture method has its own advantages, such as low requirement of technical equipment, easy operation, and possibility of drug sensitivity test at the same time. Therefore, SAT and the culture method can be used alternatively according to the clinical need.

An easy, reproducible and cost-effective method for andrologists to improve the laboratory diagnosis of non-obstructive azoospermia: a novel microcentrifugation technique

ABSTRACT This study describes a new method of microcentrifugation as an improved, viable, cost-effective option to the classical Cytospin apparatus to confirm azoospermia. Azoospermic semen samples were evaluated for cryptozoospermia by a centrifugation method similar to that of World Health Organization guidelines (2010; entire specimen centrifuged at 3000g for 15 min, and aliquots of the pellet examined). Then, if no sperm were detected, the pellet from that procedure was resuspended in culture medium, centrifuged (2000g for 15 min), and the entire pellet spread on a 4 X 6mm area of a slide and stained using the Christmas tree method (Nuclear-Fast solution and picric acid). The entire stained area was examined for the presence or absence of sperm. A total of 148 azoospermic samples (after standard WHO diagnosis) were included in the study and 21 samples (14.2%) were identified as sperm-positive. In all microcentrifugation slides, intact spermatozoa could be easily visualized against a clear background, with no cellular debris. This novel microcentrifugation technique is clearly a simple and effective method, with lower cost, increasing both sensitivity and specificity in confirming the absence or presence of spermatozoa in the ejaculate. It may represent a step forward of prognostic value to be introduced by andrology laboratories in the routine evaluation of patients with azoospermia in the initial semen analysis.

Traditional Chinese Medicine promotes the development of andrology / 中华男科学杂志

Andrology is an ancient branch of science which has gained a new development in the recent years and therefore has both traditional and modern characteristics. On the one hand, andrology keeps benefiting from the achievements of modern medicine and, on the other hand, it relies on the support of the theories of Traditional Chinese Medicine (TCM). An integration of Chinese and Western medical principles may further facilitate the development of andrology. TCM may contribute to the development of andrology by giving full play to its advantage as a psychosomatic medicine, enriching treatment strategies for male diseases with comprehensive TCM therapies, integrating the advantages of Western medicine to improve clinical efficacy, and normalizing the use of patent TCM drugs.

Correlation between premature ejaculation diagnostic tool and International Index of Erectile Function-15 in different types of premature ejaculation / 中华男科学杂志

<p><b>Objective</b>To investigate the correlation between the premature ejaculation diagnostic tool (PEDT) and International Index of Erectile Function-15 (IIEF-15) in different types of premature ejaculation (PE).</p><p><b>METHODS</b>We performed a cross-section survey among 352 PE patients received in the andrology clinic from December 2014 to December 2015 and 104 healthy men from the health examination center using basic demographic information (as on age, height, weight, education status, occupation, income, etc.), PEDT results, and IIEF-15 scores of the subjects.</p><p><b>RESULTS</b>The PE patients had remarkably higher PEDT and lower IIEF-15 scores than the healthy men (P<0.01). The PEDT score of the PE patients was negatively correlated with their total IIEF-15 score as well as with the scores in the domains of erectile function, sexual intercourse satisfaction, and overall satisfaction after adjusted for age (P<0.01). The patients with acquired PE (APE) showed a lower IIEF-15 score than those with lifelong PE (LPE) (P<0.01). The PEDT score of the APE patients was correlated negatively with the total IIEF-15 score (r=－0.391, P<0.01) and the scores in the domains of erectile function (r=－0.362, P<0.01) and overall satisfaction (r=－0.621, P<0.01), but not correlated with intercourse satisfaction, sexual orgasm, or sexual desire. The PEDT score of the LPE group was correlated negatively with intercourse satisfaction (r=－0.286, P<0.05) but not correlated with either the total IIEF-15 score or the scores in the domains of erectile function, overall satisfaction, sexual orgasm, or sexual desire.</p><p><b>CONCLUSIONS</b>PE patients have a higher PEDT score and a lower IIEF-15 score than normal males. The PEDT score of APE patients is significantly correlated with the total IIEF-15 score, while that of LPE patients is correlated not with the total IIEF-15 score but with intercourse satisfaction.</p>

Meu encontro com os outros: memórias de José de Albuquerque, pioneiro da s políticos governança políticas urbana sexologia no Brasil

A sexualidade como função fisiológica e o desejo sexual como necessidade orgânica primária. A educação sexual – para homens e mulheres – como estratégia para solucionar não só o problema das doenças venéreas, mas outros como a desarmonia conjugal e as perversões sexuais. A legitimação e institucionalização da andrologia, a ciência do homem. A crítica à abstinência sexual socialmente imposta às mulheres solteiras e viúvas. Essas eram algumas das ideias defendidas pelo autoproclamado sexólogo e andrologista brasileiro José de Albuquerque, médico que, embora tenha enfrentado tabus, levantado polêmicas e causado rebuliço na elite carioca nos anos 1930, ficou esquecido ao longo das décadas seguintes. Mas agora esse importante personagem da história da sexualidade no Brasil volta à cena com a publicação de sua autobiografia até então inédita. Enfim, para além das peripécias de uma vida bastante agitada e de uma singular trajetória profissional, a autobiografia desvela aspectos interessantíssimos do desenvolvimento das ciências médicas no Rio de Janeiro do entreguerras. Nela, aparecem seus principais personagens, a vida em suas escolas e o universo de sua prática, afirmam os organizadores. Sua leitura na segunda década dos anos 2000 permite colocar em uma nova perspectiva a própria história da sexualidade no Brasil, um campo que hoje, como nos anos 1930, continua tensionado por inúmeros dilemas, conflitos e impasses.

A bull breeding soundness evaluation system with greater emphasis on scrotal circumference

Bull breeding soundness evaluation (BBSE) is a method applied to reduce the risk of using subfertile bulls in herds. There are currently two BBSE systems, those of the Society for Theriogenology (SFT) and the Western Canadian Association of Bovine Practitioners (WCABP). Scrotal circumference (SC), sperm motility (SM) and normal sperm (NS) of 454 bulls aged between 12 and 15 months of a Spanish beef breed were used to compare both systems, and since there is no agreement on that BBSE system must be applied in Spain, a single one was proposed for its consideration. SC was adjusted to 15 months (SC15) and the mean of the BBSE traits was: SC15 (34.2±2.4cm), SM (76.6±14.6%) and NS (76.8±12.3%). In the PROPOSED system, the SM and NS thresholds were those defined by the WCABP system, while the SC15 thresholds were set by combining the SFT threshold and SC15±1SD in order to establish four classification categories, the three proposed by the WCABP system: unsatisfactory, questionable and satisfactory, and other category, called superior, for bulls with SM≥60%, NS≥70% and SC15≥Mean+1SD. The PROPOSED system scored fewer bulls as unsatisfactory than the SFT and the WCABP systems (8.6%, 23.6% and 22.5%, respectively; P<0.01), while the percentage of bulls from worst to best in the other three categories under the PROPOSED system was: 26.0%, 54.2% and 11.2%, respectively. In conclusion, the PROPOSED system gives more emphasis to SC, sets differences between bulls classified as satisfactory by the other systems and can be considered a good system for Spain and for other countries that have no defined their own system...

Gynecological theories and prescriptions for andriatric diseases / 中华男科学杂志

Andrology and gynecology have a similar or the same theoretical basis in Traditional Chinese Medicine (TCM). Andrology has a history of less than 3 decades in China, while TCM gynecology has developed for over a thousand years. The development of andrology could be greatly promoted with the guidance of the theories and prescriptions of gynecology.

Organ-sparing surgery in andrology / 中华男科学杂志

Penile and testicular tumors, especially those of the malignant nature, usually require radical excision, which alters the organ image, affects sexual and urinary functions, and consequently undermines the self-confidence and quality of life of the patient. Recent studies show that organ-sparing surgery can be an alternative to radical excision for superficial tumors and small masses. Penis-sparing surgery (PSS) has been indicated for superficial penile cancer, such as Tis and T1a lesions, and testis-sparing surgery (TSS) is feasible for benign small bilateral or solitary testicular masses (TIN). Long-term follow-ups after PSS or TSS show that the patients may retain a satisfactory appearance of the organ as well as desirable sexual and reproductive functions.

Surgical repair and reconstruction of male external genitals / 中华男科学杂志

One of the challenges in andrology nowadays is the diagnosis and treatment of external genital abnormalities and defects along with the consequent voiding, sexual, and reproductive dysfunctions, for which no guidelines are yet available. Hitherto, surgical repair and reconstruction are efficient for these diseases. The key to these operations is to individualize surgical strategies according to the specific local lesion and dysfunction, usually involving flap and graft techniques. This article presents our experience in the surgical treatment of penile and scrotal abnormalities and defects with urological and andrological techniques and microsurgical strategies, focusing on the external repair and functional reconstruction. Satisfactory treatment outcomes pivot on a precise evaluation of the disease, a rational design of surgical procedures, and an earnest communication with the patient. Some cases are rather complicated and challenging, usually with complications, and therefore deserve further researches for more effective treatment strategies in clinical practice.

The making of a good male infertility microsurgeon: learning experience at Weill Cornell Medical College of Cornell University / 中华男科学杂志

Male infertility microsurgery represents the fastest growing sub-specialty in urology and clinical andrology over the past two decades. The importance of microsurgery for male infertility has risen as a part of the urologist's armamentarium in the medical and surgical management of male infertility. Despite the advances in male infertility microsurgery in China, the lack of standardized and well-organized training programs for male infertility microsurgery remains a serious problem affecting its development. In this article, Zhao and Peng have shared their experience with the learning curve of male infertility microsurgery at the Center for Male Reproductive Medicine and Microsurgery, Weill Medical College of Cornell University, which centers on how to pay attention to the details and basic principles of microsurgery. Male infertility microsurgery is physically, technically and mentally challenging, and must be first learned in the laboratory. Clinical success depends heavily upon appropriate training in a microsurgical laboratory. Good training can significantly reduce operation time and surgical errors as well as improve the quality of outcomes.
