A fibrosarcoma of the penis is an infrequent finding. This paper contributes one case found in the perineo-scrotal region emphasising some aspects of local staging procedures, as well as the differential diagnosis with other mesenchymal tumours; there is no validated treatment protocol, although there is widespread agreement that extensive surgical excision should be performed, such as was performed in this patient.
Presentation of one case of Urethral Duplicity of the Blind Epispadias variant, also known as Congenital Prepubic Sinus. This form of accessory urethra is a congenital malformation which consists in a pseudofistular passage which starts at the proximity of the bladder's anterior side-though uncommunicated with it-and spreads to the skin of the pubic area where it ends. No other malformative condition was found in the comprehensive study conducted, and only the existence of repeat episodes of mucopurulent drainage material advised its removal. This manoeuvre was followed by a complete cure and, after more than two years follow-up, the patient remains asymptomatic.
We report a case of leiomyosarcoma of the spermatic cord that we consider singular because of the excellent outcome. The patient is alive and tumor-free 8 years following the initial diagnosis. We discuss the management of these patients, a controversial subject since there are no definitive therapeutic guidelines because of the very limited series of patients.
Presentation of one case of lithiasis as complication of female urethra diverticulum. Etiopathogenic factors, signs and symptoms, diagnosis, complications and therapy options are commented.
Three additional cases of primary adenocarcinoma of the bladder, an uncommon tumor type, seen at our department during the past years are described. These may arise from urachal remnants or metaplastic changes occurring in bladders with cystitis cystica or glandularis. Clinically, their behaviour is not unlike the rest of the infiltrating urothelial tumors. Treatment is by partial cystectomy for urachal adenocarcinoma and radical cystectomy for those arising from other sites of the bladder. Radio- and chemotherapy have a very limited efficacy in this tumor type.
We report on a case of infected solitary renal cyst following rupture and communication of the excretory tract from a ureteral calculus. The etiopathogenic mechanisms, the diagnostic difficulties encountered in this uncommon disease process, and the usefulness of radiologic and ultrasound assessment are discussed.

Report on our experience with Fabian's prothesis as alternative therapy to benign prostate hyperplasia (B.P.H.) surgery. Throughout 1990 ten patients with various surgical contraindications were implanted the above device. In spite of the series small size (10 patients) and short follow-up (4 to 11 months), we believe the 70% good results obtained is very encouraging and can either be of help to banish the ominous indwelling vesical catheter, a permanent evidence of Urologists' failure in the prostate obstructive disease, or it will allow us to relief patients with B.P.H. non-secondary to other more aggressive therapies.
A case of renal metastasis from lung epidermoid carcinoma with florid clinic is presented. We point out the great diagnostic help obtained by using Computerized Axial Tomography (C.A.T.) and echo-monitored fine needle aspiration puncture (F.N.A.P.).
Presentation of a new case of tumoral-like eosinophilic cystitis mistaken for a vesical carcinoma until completion of anatomopathological study.
An AIDS case, with a Candida urinary infection causing papillary necrosis and accompanied by occurrence of fungal lumps is reported. The paper remarks on the incidence and peculiarities of urinary affectation in these patients, emphasizing the usefulness of percutaneous nephrostomy as a diagnostic, and above all as a therapeutic procedure, in cases of expanded urinary tract.
Another case of eosinophilic cystitis is reported. Special interest is placed in the incorrectly assigned nature of this disease entity. Most of the authors tend to subdivide eosinophilic cystitis into two subtypes with its own clinical, histological, and evolutive aspects: allergic eosinophilic cystitis (AEC) and eosinophilic cystitis (EC). Several hypotheses have been put forward to explain its origin which, however, remains unclear. There is no specific treatment and its course tends to develop towards chronicity, with periods of remission and unpredictable exacerbation that warrant continuous monitoring. Diagnosis is by anatomopathological findings and differential diagnosis is warranted to distinguish it from bladder neoplasm (with which it is invariable confused), tuberculosis, etc.
We report another case of multilocular cyst of the kidney. We underscore the current theory on the neoplastic and not cystic origin of this disease entity. Attention is drawn to the confusion arising from a wide variety of terms (17) used to refer to this disease entity. Its clinical features, diagnosis, and treatment are briefly discussed. We highlight the need to follow currently available diagnostic criteria in diagnosing multilocular cyst of the kidney.

OBJECTIVES: The present study focuses attention on intermittent testicular torsion, a well-differentiated but underdiagnosed entity. METHODS: Four cases of intermittent testicular torsion are described. The presence of recurrent acute testicular pain that remits spontaneously or following self-manipulation and the horizontal of the testis (bell clapper) are sufficient to make the diagnosis. RESULTS: All four cases underwent bilateral orchipexy with excellent results. At years' follow-up all patients remain asymptomatic. CONCLUSIONS: Intermittent testicular torsion must be considered appropriately since these patients comprise the largest group at high risk for developing acute testicular torsion. Bilateral orchidopexy will ensure the viability of the testis with 100% good results.
