[Orthotopic ileal neobladder: technical procedures and long-term follow-up]. / La neovescica ileale ortotopica: note di tecnica e rivalutazione a distanza.

From January 1992 to September 1997, 29 male patients between the age of 39 and 71 affected by localized bladder cancer underwent radical cystectomy and received detubularized orthotopic ileal neobladder. In most cases we performed the ileal neobladder utilizing the Studer technique, preferring the Wallace 1 method for the uretero-ileal anastomosis, that seems to reduce the risk of stenosis. In some patients we experimented different techniques. One of these was the utilization of staplers but, at present, we are no longer using this procedure due to its high costs without any real advantage in operative time. Another technique is the performance of continuous suture in catgut 000 on the ileal aperture edges for the anastomosis with the urethra, because we believe that this method makes the ileal wall stronger. Usually we apply 6 stitches in vicryl 000 for the urethro-ileal anastomosis. In 14-28 days, after a cystography to exclude the presence of urinary fistula, the catheter was removed. 6 months later an evaluation was made utilizing an auto-evaluation questionnaire, biochemical, radiological and urodynamic examinations. The diurnal continence (96%), the nocturnal continence (71%), the renal function preservation (normal in 86% of patients), the radiological, biochemical and urodynamic (low pressure and high capacity of the neobladder) results were comparable with those published in literature. The discrete percentage of urinary refluxes observed (39%) puts in doubt the real efficacy of the undetubularized ileal tract as an antireflux mechanism, however it does not seem to determine an important reduction of renal function, as confirmed in the check up five years later. In our experience, this operation reduces the risk of stenosis of the uretero-ileal anastomosis.

[Surgery in day hospital: scrotal surgery]. / Chirurgia in Day Hospital: chirurgia scrotale.

Actually scrotal ambulatory surgery represents a necessity for the surgeon because of the more and more greatest request to admittance and because of the impossibility to admit patients with less severe diseases. Ambulatory treatments allows psychological advantage, less discomfort, less hospital complications for the patients and a reduction of sanitary expense. Light general anaesthesia with concomitant administration of local anaesthesia is performed in our Institute. Surgical treatment must be short, with low haemorragic risk, scarcely algogenic and aseptic. Since January 1994 till December 1997, 484 patients underwent scrotal ambulatory surgery in our Institute. We reported one cardiac black and two lypothymia attacks associated with anaesthesia. Therefore combined general anaesthesia results a valid technique but unvoid of complications. Ambulatory surgery for scrotal surgery represents a sure advantage for patients and for the sanitary expense.

[Seminal fluid today]. / Il liquido seminale oggi.

Semen analysis is still today a fundamental stage in male fertility diagnosis. In fact it's essential to evaluate didimal functional state and particularly the sperm genesis. But a semen analysis with normal parameters does not assure male fertility. Except the cases of azoospermia it does not distinguishes fertile from infertile patients, but when the sperm quality decrease, the pregnancy rate also decrease but rarely touch zero. Reliability of the analysis depends on the experience and on the analyst's ability who has to give an opinion about fundamental parameters like motility and sperm morphology. It is most correct to talk about semen analysis instead of semen examination because is possible to obtain not only number and quality of spermatozoa but also hormonal, immunological, bacteriological, cytogenetic, biomolecular data. Furthermore in the last ten years a lot of functional tests have been perfected, able to value accurately the integrity of some spermatozoa's "functional compartments" like membrane, acrosoma, DNA, nuclear proteins but these examinations have been considered at level assessment only for select cases. Semen analysis remains therefore a fundamental examinations in the study of male infertility even if rarely it is able to express definitive trials about infertility. In fact this always represents a couple problem, particularly of the couple in study.

[Nonsurgical and endoscopic therapy in obstructive azoospermia]. / Terapia non chirurgica ed endoscopica nelle azoospermie ostruttive.

The endoscopic therapy has an elective role in the distal obstructive azoospermia for urogenital carrefour pathologies both organics and functional and differently in the resection and/or aspiration with sperm recovery forms. Resolutely attends to the symptomatology and positively to the fertility re-establishment, in front of a short sickness-rate. The Authors describe the different techniques with relative indications, results and complications. Instead medical therapy has a role in the obstructive above all post infection and post inflammatory lesions prevention. Furthermore propose to oneself the goal to improve the seminal quality by the improvement of the semen fertilization capacity and to reduce the affections symptomatology. Finally concurs with the sperm selection techniques to fertility potential wealth.
