A review of 20 cases of conservative surgery for urothelial tumors of the upper tract is presented. The morbidity is limited; the recurrence rate is around 15% in the ipsilateral urinary tract with a mean follow up of 41 months. Conservative surgery does not seem to carry a higher fatal risk as compared to more radical surgery. It has indications in some cases which are defined.
The laparoscopic technic of nephrectomy and nephroureterectomy is presented. We discuss about the indications and contraindications of this technic. Then we present our results about our first 6 cases. We concluded that this new technic is very beneficial to the well selected patient concerning the post-operatory comfort and the early revalidation period.
The authors report their experience of 148 radical prostatectomies performed for adeno-carcinoma. They expose the reasons which have led them to adopt this kind of treatment and the reasons explaining a nearly exponential increase of the frequency of the operation during the last 5 years. They underline the importance of lymphadenectomy and the safety of frozen sections of the nodes. The surgical technique is briefly commented and the (low) morbidity of the operation is reviewed. They compare the results of RPV to those of external radiotherapy, watchful attitude or immediate hormonal treatment and they conclude in insisting on the benefit of the surgical approach as far as indications (which are defined) are strictly followed.
Extracorporeal shockwave lithotripsy (ESWL) has been initially designed for stones located in the kidney and the upper ureter. Our lithotripter is no exception. Its components (the table and the orientation of the semi-ellipsoid reflector) are adapted for the treatment of kidney or lumbar ureter stones. However, the elements forming the unit of treatment (the table, the C-arm and the Tripter) can be modified in such a way that focalization of stones of the lower ureter becomes possible through a perineal exposure. The aim is to avoid the pelvic bone shield while a good focalization of the stone is realized. From June 1989 to March 1991, 35 patients were treated for distal ureteric stones by ESWL in this original positioning.
From a new case of fibroepithelial polyp in a 41 year old woman, we reviewed literature on this rare and benign pathology, for which differential diagnosis with malignant tumor is most often obtained surgically. We emphasize both diagnostic and therapeutic advantages of endoscopic approach of this lesion.

Diabetes is a frequent aetiology of erectile dysfunction. The prevalence of erectile dysfunction in diabetics is three times higher than in the general population. Erectile dysfunction in diabetics is multifactorial. Phosphodiesterase type 5 inhibitors represent the treatment of first intention.
