L-carnitine represents a cofactor in the transport of long chain fatty acids inside mitochondria and their subsequent oxidation. Therefore, its main role is that of intramitochondrial vehicle of acyl groups. In particular, the effects of L-carnitine on the male genital function seem connected mainly with the high concentration of L-carnitine in the epididymis; the uptake of the L-carnitine from the blood is an active, in part androgen-dependent, mechanism. Moreover, epididymal spermatozoa are able to concentrate L-carnitine (while they become progressively more impermeable to such a substance) during their passage from the caput to the cauda epididymis. The main function of the L-carnitine in the epididymis is to give to the spermatozoa an energetic substrate. In fact, this function should be of great importance since the epididymal spermatozoa employ fatty acid oxidation for their energy metabolism; on the contrary, the ejaculated sperm employ glycolytic process. As a consequence of the above-mentioned effects of L-carnitine the dosage of this substance in the evaluation of the integrity of the processes of maturation of the spermatozoa was proposed. Finally, there is growing interest in the use of L-carnitine as a therapeutic tool in some forms of male infertility.","PeriodicalId":8343,"journal":{"name":"Archivio italiano di urologia, nefrologia, andrologia : organo ufficiale dell'Associazione per la ricerca in urologia = Urological, nephrological, and andrological sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1992-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"12678324","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In three cases, we performed us guided aspiration and contrast media injection of prostatic cavity. In 63 cases (1.53%) we found developmental malformations of seminal vesicles. The abnormality was bilaterally in 33% and it was associated with malformations of urinary tract in 17.46%. Other malformations were found in 0.12% cases. Ultrasonography was always able to establish obstruction level and type, and the possible associated abnormalities. US permitted to avoid or to restrict testis biopsy or vasoseminal vesiculogram.

The Authors report a brief series. It is composed with 13 patients. Their have been submitted to radical prostatectomy for prostatic cancer between January 1989 and September 1991. Pathological stage was B1 in 6 patients, B2 in 2 patients, C1 in 4 cases and C2 in 1. Particularly the role of ultrasonography in detection and follow-up of early complications such as lymphocele, pelvic hematoma and anastomotic urine leakage is stressed. Transrectal ultrasound is especially useful in the detection of urine leakage from vesico-urethral anastomosis. This technique is compared with traditional cystourethrography and advantages and disadvantages of the two techniques are discussed. Later complications of radical prostatectomy are anastomotic stenosis, pelvic recurrences, nodal or parenchymal metastasis, urinary incontinence. The role of transrectal ultrasound in the detection of anastomotic strictures is stressed, especially when the study is done during micturition. Transrectal ultrasound is not so satisfying in the detection of pelvic recurrences, especially if they are smaller than 1 cm. In case of large masses digital examination is diagnostic itself. At last the Authors describe urinary incontinence and its etiology as a complication of radical prostatectomy. Particularly a surgical technique for vesico-urethral anastomosis proposed by Rocca Rossetti and its value in post-operative continence is described. The Authors show the results of transrectal ultrasound in the detection of striated urethral sphincter and its function after radical prostatectomy.","PeriodicalId":8343,"journal":{"name":"Archivio italiano di urologia, nefrologia, andrologia : organo ufficiale dell'Associazione per la ricerca in urologia = Urological, nephrological, and andrological sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1992-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"12583984","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Since there is a close connection between renal functional units (nephrons) and vascular and interstitial compartments, alterations in intrarenal flow will obviously occur in all types of medical nephropathy, irrespective of the origin of the anatomopathological damage. Altered intrarenal flow occur with increased vascular impedance, in turn related to an increased resistance index (RI). In nephropathy with dilatation, the RI can distinguish obstructive from non-obstructive dilatation (high and normal RI, respectively). Personal experience of 80 kidneys with nonobstructive medical nephropathy has shown a good correlation between increased RI and deterioration of renal function, demonstrating that, renal function being equal, RI is higher in Vascular than Tubulo-interstitial and Glomerular nephropathies. For medical nephropathy of transplanted kidneys, Us-Doppler evaluation can be combined with conventional Doppler for diagnosing acute rejection. In this series, an elevated RI (0.90) is highly predictive of acute rejection (92% specificity) but has low sensitivity (30%). At the threshold value of RI = 0.80, sensitivity is 66% and specificity is 78%. However, it is considered that far more reliable information is obtained if Doppler examination is combined with conventional U.S. morphology.","PeriodicalId":8343,"journal":{"name":"Archivio italiano di urologia, nefrologia, andrologia : organo ufficiale dell'Associazione per la ricerca in urologia = Urological, nephrological, and andrological sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1992-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"12584907","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to avoid the difficulties of the first method and the risks in the second (like stenosis and fibrosis of the deferent duct) we propose a new simple and safe method based on the direct transperineal puncture of the seminal vesicle under direct echographic control with a transrectal probe. We have studied 16 patients, mainly in order to stage prostatic cancer; the procedure was easy to perform, well tolerated and without consequences at seminal level. It required only 30 minutes, without anaesthesia and with a very low cost. The method permits a clear visualisation of anatomical structures and of possible pathologies with particular reference to vesicular invasion by a prostatic cancer.","PeriodicalId":8343,"journal":{"name":"Archivio italiano di urologia, nefrologia, andrologia : organo ufficiale dell'Associazione per la ricerca in urologia = Urological, nephrological, and andrological sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1992-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"12678346","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
