In a first trial, double blind crossover, 62 patients have been treated with yohimbine (YOH) as ointment. About 5 mg of the drug were applied at the balanopreputial sulcus, twice daily. In 10 patients YOH was also assayed by HPLC in the blood drawn from the corpora cavernosa after the application of the drug: a rapid adsorption of the drug was demonstrated and a peak value of 58 ng/ml at 25 min. Treatment with YOH was particularly satisfactory in patients with impotence of recent onset and mild degree, that is without major vascular alterations. The active TD drug administration was tested with papaverine delivered with cavernous bodies by a C.T.D.A.S. (Controlled Transdermal Drugs Administration System). Thin layer chromatography has shown the passage of about 10% of patients a relevant amelioration of erectile function was observed.","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":"1992-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"12610802","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 such the lack of specific methods to reduce these effects brings about the necessity of special case in minimizing the loss of information. Contained in the experimental data as well as the accumulation of useless information. Recent work has suggested the extensive use of several indexes derived from combination of available variables and their respective mathematic correlation. The information obtained by following this methodology has the character of \"working hypothesis\" so it needs many favorable confirmation to assess its reliability. It is convenient to analyze a large number of relations in order to emphasize the concordant effects and discord the others. In order to obtain some preliminary indication of the reliability of this procedure we have analyzed some CMG curves in prostatic and non-prostatic subject. The final slope of the curves (urge point) t = dP/dVr has been adapted as an index of the \"elasticity\" of the bladder; it was compared with the filling volume, the muscular volume and their ratio, i.e. with a geometric index of the bladder shape. The correlation show that the index t can, to some extent significantly represent the mechanical behaviour of the bladder in its physiological condition or when there is a partial obstruction of urine deflection.(ABSTRACT TRUNCATED AT 250 WORDS)","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":"12552638","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}

This procedure is suitable for those patients affected by an obstructive nephropathy where it was not possible to insert a double \"J\" stent or where surgical treatment was not allowed. Patients affected by debilitating disease benefit from these procedure by avoiding problems connected with daily handling of catheter, examples are medications at the insertion site or possible dislodgement of a nephrostomy catheter added to the psychological problems related to carry the urine collection bag. A number of 13 patients have been treated with this method, 5 had monolateral CNC, 8 had bilateral CNC for a total of 21 procedures. All but one cause of ureteral obstruction were neoplastic, the exception being a patient with necrosis of the ureter subsequent to major vascular surgery. CNC had a residence time ranging from 1, 5 to 25 months with an average of 9.8 months. Only in 2 cases it was necessary to remove CNC due to recurrent cystitis and orchitis due to bladder irritation by a cystostomy catheter and for an obstruction which could not be remedied in a patient with necrosis of the ureter. The most important complication, i.e. obstruction, occurred in 4 cases. In the above mentioned case CNC was removed after 9 months of proper performance. In the other 3 cases obstruction occurred after 2, 3, 18 months and in all this cases obstruction was easily removed. Besides obstruction only minor malfunctions were experienced and the procedure was very well tolerated by all patients.(ABSTRACT TRUNCATED AT 250 WORDS)","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":"12583986","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}

Furthermore the incomplete excision of the corpus callosum, because of the loss of urethral tissue this involves, often leads to post-operative fistulas and stenoses. This is why, very often, there are relapses no matter what technique is adopted. In 1978 both Juraschek and ourselves published a technique, derived from Monseur, in which the urethrocele and the corpus callosum were completely excised. The resulting loss of urethral tissue was remedied with the albuginea from the ventral surfaces of the corpora cavernosa after a 180 degrees rotation of the urethra. The results of this treatment in 41 cases of recurrent urethrocele are given in this paper. The follow-up period for the patients was from 15 to 2 years. Results have been excellent with very few complications (2 post-operative fistulas and 2 urethra stenoses). There have been no relapses.","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":"12678349","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 fact, besides to document the presence of blood flow and to assess its direction, doppler US provides a quantitative evaluation of blood flow. Chromatic codification of blood flow (usually red if flowing towards the probe, blue if flowing away from the probe and yellow or green in the case of turbulence) permits to assess the presence of blood flow even in areas where a vessel cannot be depicted by B-mode ultrasonography. In fact in the study of blood flow to the kidney it's possible with color-doppler to visualize not only the main renal arteries but segmental-intraparenchymal arteries too; that is very useful in the detection of rejection of allograft. In renal artery, blood flow presents a pattern of low resistance: a brief systolic phase followed by a longer diastolic one, without inversion of flow. In renal vein, blood flow is, on the contrary, continuous. The main disorders of the kidney and urinary tract, which can be detected by color doppler are the following: renal-vascular hypertension, rejection of allograft, renal vein thrombosis, portal hypertension with spleno-renal collateral channels, disorders of ureteral motility, space occupying lesions, medical nephropathies and obstructive uropathies. Sophisticated analysis of the flow pattern to the kidney with color doppler, by some doppler sonographic parameters (resistance index RI, pulsatility index PI), in these disorders adds a functional element to the traditional ultrasonographic imaging with a better characterization of the disease.","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":"12583981","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}
