Testicular torsion is a surgical emergency in the field of urology. Knowledge of the epidemiology and pathophysiology is significant to an urologist. However, the epidemiology of testicular torsion in Korea has not been studied. We performed a nationwide epidemiological study to improve knowledge of the epidemiology of testicular torsion. From 2006-2011, the Korean Urologic Association began the patient registry service. The annual number of patients with testicular torsion from 2006 to 2011 were 225, 250, 271, 277, 345, and 210, respectively. The overall incidence of testicular torsion in males was 1.1 per 100,000; However, the incidence in men less than 25 yr old was 2.9 per 100,000. Adolescents showed the highest incidence. Total testicular salvage rate was 75.7% in this survey. There was no geographic difference of testicular salvage rate. Minimizing the possibility of orchiectomy for testicular torsion is important to improve public awareness to expedite presentation and provider education to improve diagnosis and surgery.

Low bone mass is highly prevalent among patients receiving endosseous implants. In turn, the implantation prognosis in low‐density skeletal sites is poor. However, little is known about the mechanostructural determinants of implant anchorage. Using metabolic manipulations that lead to low bone density and to its rescue, we show here that anchorage is critically dependent on the peri‐implant bone (PIB). Titanium implants were inserted horizontally into the proximal tibial metaphysis of adult rats 6 weeks after orchiectomy (ORX) or sham ORX. Systemic intermittent administration of human parathyroid hormone (1–34) [iahPTH(1–34)] or vehicle commenced immediately thereafter for 6 weeks. The bone‐implant apparatus was then subjected to image‐guided failure assessment, which assesses biomechanical properties and microstructural deformation concomitantly. Anchorage failure occurred mainly in PIB trabeculae, 0.5 to 1.0 mm away from the implant. Mechanically, the anchorage performed poorly in ORX‐induced low‐density bone, attributable mainly to decreased trabecular number. iahPTH(1–34) rescued the PIB density and implant mechanical function by augmenting trabecular thickness (Tb.Th). However, implant biomechanical properties in low‐density bone were relatively insensitive to implant surface treatment that affected only the osseointegration (%bone‐implant contact). These results support a model wherein anchorage failure involves buckling of the weakest trabecular struts followed by sequential failure of the stronger trabeculae. Treatment with iahPTH(1–34) induced thicker struts, which were able to delay and even prevent failure of individual elements, thus implicating trabecular thickness as a prime target for enhancing implant anchorage by systemic bone anabolic therapy. © 2010 American Society for Bone and Mineral Research. 相似文献

目的 研究去势对戊四氮点燃大鼠癫痫模型行为学表现的影响.方法 采用戊四氮腹腔注射制作癫痫大鼠模型,对照研究去势大鼠同正常大鼠的潜伏期及持续时间等行为学表现.结果 大鼠癫痫模型全部点燃,去势组平均潜伏期(8.09±0.89) min((-x)±SD)长于非去势组的(3.94±0.65) min((-x)±SD).发作时间也有所缩短,去势组(19.16 ±3.06) min((-x)±SD)略短于非去势组的(26.37±2.90) min((-x)±SD) (P <0.05).非去势组点燃时间明显短于去势组,非去势组平均点燃时间(20.83±6.15) d((-x)±s),而去势组平均点燃时间(24.6±5.64) d((-x)±SD).结论 戊四氮点燃大鼠致痫模型是一种成熟的、较为安全的癫痫模型.去势后,SD雄鼠较正常非去势SD雄鼠相比致痫潜伏期延长、持续时间缩短、发作频率及程度减轻,点燃时间也明显长于正常SD雄鼠. 相似文献

A 29-years-old male patient presented with complaint of the small size of his left testicle. The physical examination revealed
a normal right testicle with 15 cc volume, a small left testicle (5 cc) and a 4 cc mass under the left testicle, which was
thought to be a spermatocele. Ultrasonographic imaging was performed and the mass was defined as a third testicle with a heterogenic
epididymis. Scrotal magnetic resonance imaging (MRI) confirmed the diagnosis. An inguinal exploration was performed, which
resulted in a left orchiectomy and biopsy of the superior left testicle.
The pathologic examination revealed hyperplasia with microcystic changes in the orchiectomy specimen and severe hypospermatogenesis
in the biopsy sample. There were no significant changes in semen analysis after the operation. 相似文献

Transgender women may opt for genital gender-affirming surgery (gGAS), which comprises bilateral orchiectomy, gender-affirming vulvoplasty, or vaginoplasty. Vaginoplasty is chosen most frequently in this population, penile inversion vaginoplasty being the surgical gold standard. In selected cases, skin graft vaginoplasty, intestinal vaginoplasty, or peritoneal vaginoplasty may be indicated. In this article, we discuss the various types of gGAS for transgender women, (contra)-indications, intraoperative considerations, techniques, surgical outcomes, and postoperative patient-reported outcomes. 相似文献

ObjectiveTo evaluate the indications and histology of our series of orchiectomies, analysing the results by patient's age.MethodsWe included the orchiectomies realized in our hospital between 2005 and 2020 in patients older than 18 years. We estimated demographic data, indications, histology and effectiveness of testicular ultrasound by three groups of age.ResultsWe included 489 orchiectomies, which 364 (74%) belonged to group A (patients between 18-50 years), 59 (12%) to group B (50-70 years) and 66 (14%) to group C (older than 70 years). In group A, 284 (78%) orchiectomies were indicated due to malignancy suspect. In 91.9% cases (261) malign neoplasm was confirmed at final histology and 253 (89%) were germinal cells. Testicular ultrasound had a positive predictive value (PPV) of 90% in this group. In group B, 34 (57%) orchiectomies were indicated because of malignancy suspect. At final histologic analysis, 25/34 (73.5%) confirmed malign neoplasm. Ultrasound had a PPV of 68%.In group C, orchiepididymitis was the main cause of testicular removal with 30 cases (45,5%). From the 20 cases (30.3%) with suspicion of malignancy, only 6 had confirmed malign histology. Testicular ultrasound PPV for malignancy was 31%.ConclusionIn patients younger than 70 years the main orchiectomy's indication was suspect of malignancy and in older than 70, testicular inflammation. The germinal neoplasm was the predominant histology in younger than 70 years. In older than that, malignancy was infrequent. The positive predictive value of testicular ultrasound for malignancy decreased with patient's age. In patients older than 50 years proper image diagnosis to assess malignancy should be considered before orchiectomy is done. 相似文献
