Sonographically detected testicular microlithiasis and testicular carcinoma

Testicular microlithiasis is an uncommon abnormality that produces the characteristic sonographic appearance of diffuse, punctate, hyperechoic foci throughout the testicular parenchyma. We have detected this distinctive sonographic pattern in 4 patients during a seven-year period. Three of the patients had proven concurrent testicular carcinoma. We describe our experience and review previous reports of testicular microlithiasis. We conclude that testicular microlithiasis may be associated with testicular neoplasia, and advocate particularly careful evaluation and followup of the testes when this abnormality is detected. © 1993 John Wiley & Sons, Inc.     

A case report of transverse testicular ectopia with testicular microlithiasis

Transverse testicular ectopia is a rare congenital anomaly in which both testes migrate along the same inguinal canal toward the scrotum. This report describes the case of the rarest form of transverse testicular ectopia in a 23‐year‐old man with coexisting testicular microlithiasis in one of the two testes as diagnosed on sonography and confirmed on MRI. We are unaware of any previous published reports of this association. Although the etiology of both conditions is debatable, each is believed to be associated with an increased risk of testicular malignancy, and this poses a dilemma for the future management of this patient. © 2014 Wiley Periodicals, Inc.

Brucellar testicular abscess: a rare cause of testicular mass

Brucellosis is an endemic disease in Turkey, and testicular abscess is a rare and frequently misdiagnosed complication of brucellosis. In the literature there are only seven reported cases, and all were treated with both medical and surgical therapy. We report a case of brucellar testicular abscess treated with medical therapy only. Although the patient recovered clinically at the end of 6 weeks, the regression of the testicular lesion could not be observed until after 5 months.     

彩色多普勒超声对睾丸扭转后存活力的预测价值

目的 探讨彩色多普勒超声(CDU)预测睾丸存活力的临床价值.方法 比较42例睾丸扭转患者的临床表现、术中所见及手术前后阴囊CDU表现,将术中睾丸活力分为A～D级,保留A～C级活力睾丸,切除D级活力睾丸.将CDU随访的术后睾丸存活力分为Ⅰ～Ⅲ级,Ⅰ～Ⅱ级睾丸存活,III级睾丸萎缩.结果 42例中睾丸复位17例,切除25例.复位组睾丸存活7例,术中睾丸活力分别为A级2例,B级3例,C级2例,术前CDU主要表现为:睾丸实质回声均匀,血供减少或消失;睾丸局部片状或放射状低回声,大部分实质尚存血供.萎缩10例,术中睾丸活力分别为C级8例,D级2例,术前CDU(包括切除组25例)主要表现为睾丸大片放射状低同声或弥漫性明显回声不均匀,无或仅睾丸边缘少量血供.复位组与切除组的健侧睾丸CDU随访无明显异常发现.结论 阴囊CDU检查能够预测复位后睾丸的存活力,CDU评价后及时手术是提高扭转睾丸存活力的关键.     

睾丸扭转诊治的探讨及误诊分析

目的探讨睾丸扭转的诊治经验及误诊原因,提高诊治水平。方法对23例睾丸扭转患者的临床资料进行分析总结。结果左侧睾丸扭转14例,右侧9例,发病至就诊时间3 h至10 d。其中22例接受手术,1例手法复位,18例切除睾丸,4例行睾丸复位固定。22例手术均未行健侧固定亦未再出现睾丸扭转。结论睾丸扭转的早期诊断,尽早手术探查是避免睾丸坏死的关键。     

睾丸生殖细胞肿瘤及睾丸原位癌中鞘糖脂GB3的表达及意义

目的检测鞘糖脂神经酰胺三己糖苷(GB3)在睾丸生殖细胞肿瘤及睾丸原位癌组织中的表达,并探讨其临床意义。方法应用免疫组化方法检测62例睾丸生殖细胞肿瘤及14例睾丸原位癌组织标本中GB3的表达。结果 62例生殖细胞肿瘤中,54例GB3(+)(87%);14例睾丸原位癌中,11例GB3(+)(78.6%),其中8例强(+),其曲细精管内支持细胞及残留生精细胞均呈GB3(-)。结论睾丸原位癌是睾丸生殖细胞肿瘤早期阶段,睾丸生殖细胞肿瘤及睾丸原位癌细胞中鞘糖脂成分GB3改变,提示GB3在睾丸生殖细胞肿瘤发生发展过程中起着作用。GB3可作为睾丸生殖细胞肿瘤标记物,特别在睾丸原位癌早期诊断中有实用价值。

Penile and testicular disorders

Circumcision, priapism, phimosis, Peyronie's disease, orchitis, epididymitis, and testicular torsion are conditions of the male penis and testicles that warrant increased attention by health care providers in practice. Healthy outcomes for penile and testicular disorders can be achieved through education, enhanced screening, and adequate comprehensive treatment. Penile and testicle disorders provide researchers and clinicians with many opportunities for research and practice that can improve the condition of men's health.
