精索静脉曲张导致不孕机制及治疗分析

精索静脉曲张(VC)是男性尤其是生育期男性常见的一种泌尿生殖系统疾病。WHO已将VC作为引起男性不育的首要原因。但目前的研究仍然没有明确其发病机制,因此探讨精索静脉曲张致男性不育的机制具有重要意义。其发病机制虽不明确,但手术治疗可以明确改善VC患者的不孕状况。这个结论已在临床上得到了大多数学者的认可。     

Varicocele

Whether varicocoele should be treated while the patient is young remains controversial in spite of the high prevalence of this problem and the fact that it is believed by many to be a causative factor in male subfertility. Varicocoele is mostly asymptomatic and the diagnosis is made nowadays during routine clinical examinations. Döppler examination confirms Valsava-induced reflux and ultrasonography can detect intrascrotal abnormalities and allow accurate visualization of testicular size. Increase in retrograde venous flow, with decrease in testicular volume, are two proven mechanisms. Histological lesions worsen with time and disturbance of spermatogenesis become prominent with passage through puberty. Treatment of varicocoele is indicated in cases where the varicocoele is larger, if it is symptomatic, in youths with arrested testicular growth, and when a varicocoele enlarges with time. Two treatment options exist: a direct surgical approach or endovenous occlusion. Whichever method is employed, results must be confirmed by ultrasonographic and Doppler examinations.     

Operative Treatment of Typhoid Perforation of the Bowel

One hundred and twenty-one proved cases of typhoid perforation were seen in a three-year period; the incidence of perforation, 17·9%, is the highest recorded. All patients were treated by laparotomy with closure and drainage. The mortality was 29·8%, but 76% when operation was performed after the fifth day of perforation.
