RESUMEN
Prostatic endoscopic resection (TURP) is a reference method in the treatment of prostatic obstruction. In the past decades, the method used a monopolar resectoscope. In the last years, various technologies have been studied to improve the efficacy of endoscopic resection. As per our experience, we have thence ascertained the variations of the hematic crasis and of the mictional asset in TURP patients treated with bipolar knives. 20 patients underwent bipolar plasmakinetic resection of the prostate. Their age ranged between 58 yrs and 82 yrs (av.: 70.2 yrs), the adenoma volume, checked with TR ultrasound scanning, was between 33 and 44 cc (av.: 37.6), the Qmax was between 6.4 and 9.0 mL/min (av.: 7.42 mL/min). A 24Ch resectoscope and spinal anesthesia were used. Bleeding during resection was never relevant; therefore resection never had to be stopped. After about 36 hours from surgery, the patients' sanguification was checked again: a 6.53% reduction of the number of erythrocytes, compared to pre-surgery data, was observed, together with a 6.73% decrease of hemoglobin concentration, and a 6.3% decrease of hematocrit. Continuous irrigation was suspended during the first day, catheter was removed on the 48th hour in 15 cases, and on the 72nd in 5 cases: the patients were discharged on day 3 in 16 cases, and on day 4 in 4 cases. A flux evaluation was performed after 3 months, which showed a Qmax between 16.6 and 24 mL/min (av.: 19.11), with a significant increase in the maximum flow rate. The use of the new technologies in prostatic endoscopic resection has allowed us to improve the efficacy of such a method. Above all, the use of a bipolar electrosurgical knife enables us to associate a basal hemostasis with the resection of the prostatic tissue. Thus, the hematic loss is low, as we have been able to ascertain also in our own experience. This gave us the possibility to quickly stop continuous irrigation and to early remove the catheter. This way, hospitalization was sensibly reduced (av. 76.8 hours). The maximum flow rate, in the short term, has been good. We have been able, in our experience, to assess that this technology represents a useful guarantee to improve the results of prostatic endoscopic resection.
RESUMEN
Diabetes is an important risk factor in erectile dysfunction (ED), acting via several mechanisms. We assessed the efficacy of intracavernous injections (ICI) rehabilitation and oral systematic therapy in diabetic patients, as well as the response of controls to oral therapy 'on demand'. MATERIALS AND METHODS. Sixteen diabetic patients with ED were treated with vasoactive drugs orally when needed, without satisfactory erections. The patients underwent then ICI rehabilitation with PGE1 20 mcg twice weekly for 4 weeks, followed by the administration of oral drugs twice weekly for 4 weeks. Before and after rehabilitation, the patients completed a detailed anamnestic protocol to study their libido (always present); they answered questions Q3 and Q4 of the IIEF questionnaire. During ICI, a study with dynamic echocolordoppler (ECCD) was carried out. All patients had Type 2 diabetes: 10 were treated with oral antidiabetics, 4 were treated with insulin, and in the other 2 patients, treated with insulin, a sensitive neuropathy of the lower limbs was diagnosed. Fourteen patients were treated with antihypertensive drugs. RESULTS. Before rehabilitation, the mean responses to questions 3 and 4 of the IIEF (International Index of Erectile Function) questionnaire were 1.6 and 1.5 respectively; after rehabilitation, the mean responses were 2.68 and 2.5, respectively. The ECCD test showed an arterial component in 4 cases and a high end-diastolic velocity (EDV) in 14 cases. Four patients (25%), 2 of which had neuropathy, and 2 were in advanced age, did not respond to PGE1 or to oral therapy, 4 patients (25%) (2 treated with insulin and 2 by oral therapy) responded to ICI but not to oral therapy, while 8 patients (50%) showed a good response to both injectable and oral therapy, with good Q3 and Q4 scores. CONCLUSIONS. Good endothelial function appears to be essential for the maintenance of acceptable erectile function. Diabetes has a negative effect on this function, as does hypoxia and low perfusion. Based on the principle that a good erection improves endothelial function, we tried to determine if oral systematic and intracavernous rehabilitation would improve erectile function in diabetic patients. The results indicate that diabetes interferes with erectile function, compromising the effects of the vasoactive drugs. However, integrated systematic rehabilitation appears to allow a good erectile response to both intracavernous and oral therapy in a large number of cases. Therefore, we support this kind of rehabilitative protocol in the treatment of ED in diabetic patients.
RESUMEN
After radical cysto-prostatectomy the bladder substitute is made from an ileal segment, opened along its antimesenteric border and folded; the results are in general good. The success of this procedure demands attention to detail, hemostasis and gentle handling of tissue so this surgery depends an unusual degree of commitment to meticulous technique. The very low rate complications, obtained with mechanical sutures in gastrointestinal surgery, incited the Authors using the staplers GIA and TA Polysorb for detubularized ileal segment. They are very manageable, easy to use and the follow-up shows the absence of urinary stone; so the team approach is less tedious and strenuous. The Authors present their results of 11 neobladder-staplers made with 35 cm of detubularized ileal segment without folding.

The standardisation of diagnostic procedures according to an adequate sequence is a mandatory in determining the therapeutic strategy in liver traumas. In a series of 26 consecutive cases of trauma of the liver, 3 of them penetrating, we adopted a diagnostic algorithm based on the extensive use of sonography and "Injury Severity Scores" in addition to the standard clinical procedures. The treatment of the lesions was surgical in 21 cases (81%) and conservative in 5 (19%); post operative mortality was 14% and overall mortality 11.5%. None of the cases treated by conservative approach had to be submitted to surgery during the follow-up period. Sonography, carried out by surgical staff within 30' from observation and at definitive intervals, allowed a correct surgical approach in all cases; a similar sensitivity was obtained by sonography also in the cases treated conservatively and submitted to C.T. evaluation. The absolute correlation between Revised Trauma Score, Injury Severity Scale, classes of severity of the lesions and subsequent surgical survey suggest that this scoring system could be adopted in the first triage of traumatic lesions of the liver. Sonography could be preferred to diagnostic peritoneal lavage in the screening of cases with circulatory instability; furthermore, it could be a valid alternative to C.T. in hemodynamically stable patients.
