睾丸微结石症

睾丸微结石症(testicular microlithiasis,TM)是以睾丸内多发钙化为特征的一种临床综合征.微结石症由Priebe等[1]于1970年首次报道.1987年Doherty等[2]首次描述了TM的声像图特征.虽然TM的预防及治疗目前尚鲜见报道,但TM的病因、发病机制、流行病学及超声表现,特别是与男性不育的相关性,已引起学者的重视,现综述如下.

睾丸微结石症对睾丸功能的影响分析

目的了解睾丸微结石症(TM)对睾丸功能的影响,评估TM患者精液质量和血浆性激素水平。方法生育年龄要求生殖健康体检者为对象,通过物理检查,精液分析、生殖系统超声和性激素检查评估睾丸功能,其中诊断TM患者43例,精索静脉曲张(VC)45例和健康人(NC)45例作为对照组。结果本研究TM、VC和NC3组平均年龄分别为(33.25±5.81)岁、(31.85±7.26)岁和(30.13±6.09)岁,3组年龄比较无显著性差异(P>0.05)。TM组睾丸体积、精子密度、活力、活率和血清游离睾酮水平均显著低于NC组(P<0.05),但与VC组比较无显著差异(P>0.05)。结论TM显著影响睾丸功能包括生精功能和睾酮分泌功能,其机制有待于进一步研究。

Testicular microlithiasis: report of 14 cases

Testicular microlithiasis (TM) is a comparatively rare condition in which calcified congelations fill the lumina of the seminiferous tubules. Using high-frequency linear transducers (10 MHz), TM is easily demonstrated as tiny punctate echogenic foci, which typically do not give an acoustic shadow, and is classified into classic type (CTM) and limited type (LTM) on the basis of the presence of five or more microliths at least on one image of the testes. Fourteen patients were found to have TM, 6 of which were LTM and 8 were CTM. In one patient with CTM, coexisting mixed germ cell tumor (seminoma, embryonal cell carcinoma) was demonstrated. Until further data are available, it seems reasonable to consider patients with TM as having an increased risk of developing a primary testicular tumor.     

Testicular microlithiasis: Case report and literature review

We present an interesting case of bilateral microlithiasis. Microlithiasis is usually considered a benign condition with no need for follow-up. However, when a patient with testicular microlithiasis has a positive family history of testicular cancer, such patients should be followed up closely to detect the development of testicular cancer.     

Testicular microlithiasis

Testicular microlithiasis is an uncommon condition that is characterized by calcifications within the lumina of seminiferous tubules. It is usually an incidental finding on high frequency scrotal sonography. Testicular microlithiasis is a benign condition but is associated with testicular malignancies. Recent reports support this association and suggest regular follow-up in these patients.     

Testicular microlithiasis: a case report and review of the literature

Testicular microlithiasis (TM) is a rare condition in which men have innumerable testicular calcifications. It is increasingly being reported on ultrasound. The published literature has reported an association between confirmed testicular malignancy and testicular microlithiasis. The relationship between TM and the risk of developing malignancy is unclear. The present paper reports a patient with a previously normal scrotal ultrasound except for bilateral sonographically detected TM who developed a testicular tumour. It also discusses the appropriate management of TM after reviewing the published literature.     

Testicular microlithiasis in male infertility

Testicular microlithiasis was found in a 30-year-old infertile man. The literature is reviewed and the possible influence of testicular microlithiasis on male infertility is discussed.     

Testicular microlithiasis in Taiwanese men

Testicular microlithiasis (TM) is an unusual ultrasonographic manifestation in testicular parenchyma. Limited information is available about TM in Taiwanese men. We performed a retrospective analysis to investigate the characteristics of TM and its association with testicular cancer and infertility in Taiwan. Male patients who had received scrotal ultrasonography because of scrotal symptoms or infertility between January 2000 and December 2003 were recruited. The incidence of TM was 7.6%. Both testicular microlithiasis and testicular cancer occurred chiefly in the third decade. Patients with TM exhibit a higher chance of testicular cancer (6% vs. 0.9%). No local field effect between TM and testicular cancer was observed. Testicular microlithiasis severity is not positively correlated with sperm quality and sterility. Forty-eight patients (32%) were available at follow-up. No patient developed a testicular tumor or elevated tumor markers (AFP, beta-hCG) during follow-up. We suggest monthly self-examination, annual scrotal ultrasonography and tumor markers screening between the age of 20 and 30 years of patients with TM.     

Testicular abscess: report of 2 cases

We report two cases of testicular abscess. The first case is in a 53-year-old man who had been suffering from diabetes mellitus. Because of cerebral infarction, he had been bedridden and a Foley catheter had been indwelt for a long period of time. The second case is in a 78-year-old man who had suffered from acute prostatitis six months earlier. In both cases, the chief complaints were high fever and painful scrotal swelling. At initial evaluation, ultrasonography revealed that the affected testes were swollen without abscess formation and an ipsilateral epididymal swelling was demonstrated in the second case but not in the first case. The urine bacterial culture (UBC) result was positive for Escherichia coli in first case and Pseudomonas aeruginosa in the second case. In both cases, fever and scrotal pain subsided after antibiotic chemotherapy, and inflammatory reactions on routine blood studies were normalized within 2 weeks. Nevertheless, the swollen testes did not sigunificantly reduce in size, and testicular abscess was suspected by magnetic resonance imaging (MRI). Orchiectomy was performed, and intratesticular abscess formations were confirmed macroscopically and microscopically. In each case, bacterial culture from the abscess was positive for the same bacterium as detected from the UBC. It is difficult to distinguish testicular abscess from acute epididymitis at the early stage because of similarities on symptoms or signs between the two. If testicular swelling lasts after appropriate chemotherapy, we believe that attention should be directed to testicular abscess, which needs orchiectomy to obtain a complete cure and MRI is useful in its diagnosis.
