Summary—The influence of 12 clinical and social factors on the length of post‐operative stay in hospital after transurethral resection of the prostate was investigated in 100 patients. Using a multiple binary regression analysis, the factors significantly associated with a post‐operative stay exceeding 6 days were: patient's age>70 years (P<0.005), the presence of existing cardiovascular disease (P10g (P<0.005). The first two factors are useful in providing a prediction of prolonged post‐operative stay. The results indicate that those factors associated with a prolonged post‐operative stay are beyond the control of the

摘要:

Summary—Thirty‐four patients with TO carcinoma of the prostate were revived in an attempt to correlate their clinical progress with the histopathological features of the tumour at presentation. Two different grading systems were used. It was found that no matter which system was used, the poorer the histopathological grade the poorer the progno

Summary—The initial investigation and diagnosis in 28 patients with posterior urethral trauma are presented. Twenty‐five patients underwent either primary realignment for complete rupture or cystostomy alone for partial rupture. The results of their management are repor

摘要:

Summary—In the last 3 years 268 patients with urethral strictures have attended this unit. We treat most strictures by urethrotomy and consider an open operation only after two recurrences or in patients whose strictures are considered unsuitable for urethrotomy. Open operations have been performed on 42 patients. Although several types of operation have been used, most comprised an end‐to‐end anastomosis or Blandy's scrotal flaps.In the last few years a split‐skin mesh graft has been used to replace the posterior urethra and the advantage of this technique is that the new urethra is soft and hairless. We present our experience with this method and our overall

摘要:

Summary—Scrotal ultrasound scans carried out on 156 patients were reviewed in a retrospective study and the sonographic findings and indications evaluated. Ultrasound was able accurately to distinguish the normal from the pathological scrotum. Extratesticular lesions were readily differentiated from testicular lesions. Abnormal testicular echo patterns were usually associated with tumours, but orchitis, granulomas and haematomas were found to have a similar appearance. Occult testicular tumours could readily be identified. Ultrasound was also useful in excluding underlying pathology in hydroceles, in the diagnosis and follow‐up of epididymitis and other epididymal lesions and in the assessment of underlying testicular damage in traumatic haematoceles. Ultrasound may also be useful in post‐orchiectomy follow‐up examinations to exclude tumour in the contralateral

摘要:

Summary—Four adenomatoid tumours of the epididymis were embedded in paraffin wax, sectioned and the sectioned surfaces examined by scanning electron microscopy using the secondary electron mode. The solid faces of the sectioned neoplasms were damaged by the preparative technique but the depressed luminal surfaces of the tubules were well preserved and yielded useful information. Large areas of luminal surface were examined and the presence and distribution of microvilli were noted. In addition, there was a more complex cell surface pattern of intersecting cord‐like elevations. Desquamating cells were seen within the tubules and the cytoplasmic bridges noted by light microscopy were shown to be thin cytoplasmic partitions. These findings are consistent with the mesothelial theory of histogenesis.Scanning electron microscopy can provide useful information about the internal structure of neoplasms even with simple preparative techniq

摘要:

Summary—Two methods of statistical analysis were used to evaluate the results from an infertility clinic (the couple‐months method and Cox regression analysis). The results were in general agreement and validated the couple‐months method. The total trying time, sperm motility, sperm density and results of the wife's investigation were all shown to be highly significant prognostic factors. The age of either husband or wife, semen volume, sperm morphology, size of the testes, presence of a varicocele, serum LH and serum testosterone all failed to give significant additional prognostic information. High serum FSH and testis asymmetry both gave weak additional prognostic information.The benefit of attendance at the infertility clinic was evaluated in two ways: firstly by testing whether the event of clinic attendance altered prognosis and secondly by examining the results of a broad range of treatments. The results showed that attendance at the clinic with subsequent treatment did not improve the chance of fertility. The main benefit from clinic attendance was that the couple could be given an accurate prognosis and supportive counse

摘要:

Summary—From a computer file of 955 couples attending hospital because of an infertile marriage, 279 were identified where the female partner had normal investigation results. Follow‐up information was available for all couples and the fecundability (conception rate per month) for the first year of follow‐up has been calculated, stratified according to the husband's investigation results. The fecundability of couples where the wife had normal investigation results but the husband had reduced sperm density ranged from 0.4% for wives with azoospermic husbands to 5.9% when the husband had at least 10 million motile sperm/ml. For any given number of motile sperm the fecundability was also strongly dependent on the duration of involuntary infertility as recorded at the time of initial clinic attendance.In view of the lack of effective treatment for most male infertility the fecundability rates reported herein are likely to represent those that would be found in an untreated population and should be useful as a base line when evaluating results of new treat

摘要:

Summary—Haemostatic changes in the penile and systemic blood during erection were studied in the Chacma baboon. Dynamic hypercoagulability developed in the penile blood and fibrin was deposited on the endothelium of the penile artery and trabeculae during erection. These suggest that penile hypercoagulability predisposes to ageing penile vascular change

摘要:

Summary—This investigation assessed a biodegradable collagen membrane which can be sutured around the ureter to prevent urine leakage, thus permitting healing to proceed more rapidly while the membrane itself is resorbed.Following an earlyin vitroinvestigation in which collagen was assessed, a more comprehensive survey has now been carried out. Tissue compatibility and biodegradation were assessed by implanting the film into the lumbar muscles of rats; it was then used to cover experimental ureterotomies in New Zealand White rabbits.The data obtained from the rabbits confirmed that a collagen membrane can prevent leakage of urine from the ureter during healing while it itself is biodegraded, indicating that a collagen membrane could be used to repair the injured urinary trac
