RESUMO
Investigation of vesico-urethral and sweating function was performed in twelve patients with classical idiopathic Parkinson's disease and ten patients with parkinsonism associated with features suggestive of more extensive involvement of the nervous system, as in the Shy-Drager syndrome. The urodynamic studies revealed detrusor hyperreflexia with reduction of maximal cystometric capacity in only one patient with Parkinson's disease (8%), but in nine patients with parkinsonism associated with other features (90%). Urethral sphincter electromyography did not indicate denervation in any patient of either group. Delayed or incomplete relaxation of the urethral sphincter during micturition was observed in seven patients with Parkinson's disease (58%) and in two patients of the other group (20%). Decreased sweating responses were found in both groups of patients when compared with control subjects. Hypohidrosis was more pronounced in parkinsonism associated with other features than in Parkinson's disease. Differences in sweating between the two sides of the body were observed in both groups of patients. Although there are differences in vesico-urethral and sweating function, they do not precisely differentiate between patients with classical Parkinson's disease and those with parkinsonism associated with features suggestive of more extensive involvement of the nervous system.

Renal cholesteatoma is an extremely uncommon disease. The renal pelvis is the most common site, but the lesion can be localized, even if rarely, in a calix or in the ureter. Histologically it consists of a keratinizing desquamative squamous metaplasia, with absence of cellular atypia in the urothelium, therefore cholesteatoma is not considered as a premalignant lesion. Authors report a case of renal cholesteatoma and take into consideration particularly the question regarding the diagnostic approach, that in spite of the help of new imaging techniques, as TC, is unable to arrive at a certain diagnosis, and the therapeutic approach, that must be conservative, when it's possible and according to the majority of Authors.
