The intravenous immunotherapy with high-dose interleukin-2 (IL-2) would constitute one of the most effective treatments of metastatic renal cell carcinoma (RCC). More recently, IL-2 subcutaneous therapy has also appeared active, either alone or in association with interferon, with results comparable to those found with the intravenous route of injection, but with a lower toxicity. On this basis, we have designed a protocol of treatment with low-dose IL-2 alone given subcutaneously as a first or a second line therapy in metastatic RCC. The study included 60 consecutive patients (pts) (M/F: 39/21, median age 56 years, range 26/74). IL-2 was given at a dose of 3 millions IU twice/day for 5 days/week, for 6 weeks, corresponding to one cycle. In non progressed pts a second cycle was repeated after a 28-day rest period. Dominant metastasis sites were, as follows: soft tissues: 8; bone: 11; lung: 29; liver: 3; liver plus lung: 7; adrenal: 2. The minimum follow-up was 18 months and the median follow-up was 34 months (range 18-48). A complete response (CR) was achieved in 2/60 (3%) pts. A partial response (PR) was obtained in 15/60 (25%). Therefore, tumor objective rate (CR + PR) was 17/60 (28%). The median duration of response was 13 months (4-33).(ABSTRACT TRUNCATED AT 250 WORDS)

Benign prostatic hypertrophy provokes clinical manifestations correlated on one hand to a static obstructive component, due to the increase in glandular size, and on the other hand to a dynamic component, controlled by the alpha adrenergic autonomic system which gives the smooth muscular tonus of the prostatic adenoma. The alpha adrenergic receptor block reduces the dynamic component, improves the clinical and urodynamic parameters determined by the infra-bladder obstruction in patients with BPH. The selective alpha 1, long acting antagonists especially, such as terazosin, offer a safe and efficient therapy for selected patients suffering from BPH. They also have the indisputable benefit of mono-administration. In this study the basic concepts of BPH treatment with terazosin are discussed.

The technique for radical cystoprostatectomy was modified to avoid injury to the branches of pelvic plexus that innervate the corpora cavernosa (monolateral neurovascular bundle preservation or "Nerve sparing technique"). The studies of Walsh and coll. demonstrated that the branches of pelvic plexus that innervate the corpora cavernosa are situated between the rectum and urethra and penetrate the urogenital diaphragm near to the muscular wall of the urethra. Injuries to the pelvic plexus can occur during 1) division of posterior pedicle of bladder (the seminal vesicle can be used as a landmark intraoperatively to avoid injury to pelvic plexus), 2) during apical dissection of prostate with transection of the urethra. The return of sexual function postoperatively is related to preservation of autonomic innervation; the excision of the neurovascular bundle on one side may prevent impotence in 68% patients. Our study was undertaken to identify the cause of impotence in men undergoing radical cystoprostatectomy with "Nerve sparing technique" using bulbo cavernous reflex. Our results suggest that bulbo cavernosus reflex may not be a sensitive clinical tool to establish a diagnosis of neurogenic erectile dysfunction after pelvic surgery. The Authors examine the recent neuro-uro-physiological diagnostic methods for the study of neurogenic erectile dysfunction.

Endoluminal sonography performed with 12.5 MHz miniature transducer-containing catheters with diameter of 6 or 9 Fr., is a new technique for the study of urinary tract. We studied: U.S. scan of 10 corpes and 10 operatory specimens (bladders and kidneys) with anatomic measurement in vitro. U.S. scan of 20 patients "in vivo" with pathologies involving bladder and upper urinary tract. We studied the normal anatomy of bladder and ureter by U.S. and we detected the structures beyond the ureteral lumen as: vessels, lymph nodes, muscle. Our indications for the utility of this new U.S. technique are: Detection and staging of superficial T.C.C. of the bladder. Detection of dangerous vessels near the U.P.F before endopielotomy. Excretory tract minus (endoluminal ultrasound is helpful in differentiating such pelvic filling defects as blood clots, no opaque stones and transitional cell carcinoma).

Infection by the HIV virus affects the urogenital system in a minor percentage of cases in comparison to other organs such as the lungs, the central nervous system and the haemolymphopoietic system. In recent years however, with the continued spread of the disease also urologists find themselves dealing with the various urogenital pathologies that are presented in seropositive or fully-blown Aids patients. The Authors present their experience and describe the problems correlated to the dealing with acquired immune deficiency syndrome patients that are affected with urogenital pathologies.

While the invasion of the bladder by neoplastic cells during acute lymphatic leukaemia in children has been reported by various authors, the leukaemic invasion of the bladder in adults is extremely rare. We report a case of recurrence of A.L.L. in the bladder presenting colicky symptomatology and obstruction of the excretory tracts.

Penile metastases are uncommon lesions: most often secondary to a primary pelvic cancer (prostate, bladder and rectum) they have a unfavourable prognosis. The appearance of disseminations is still controversial and there is not an efficacious therapy. Priapism may be present or not. The Authors report their experience on a penile metastasis secondary to prostatic cancer and about the evolution of this pathology. A review of the Literature is done.

The Authors report their recent experience about a penis trauma with a subtotal organ skinning. After the literature analysis, the AA. explain the case, with a particular attention to the surgical repairing technique. The surgical outcomes are discussed and it is re-marked the necessity of a precise diagnostic approach and follow up, also to prevent possible unerectional chains.

The Authors discuss a recent case report treated with radial cystectomy associated with a secondary urinary derivation using the caecum-colon reservoir. After having reviewed the various surgical procedures involving the urinary derivations, the Authors describe the technique used by them paying particular attention to the positive aspects of having a low filling pressure reservoir controlled by a valid sphincter ileum-caecum valve. Considering the good postoperative result with this method, the Authors regard this procedure as an alternative to other urinary derivation techniques when carried out with correct indications.
