[Transformation of glandular cystitis into bladder transitional carcinoma with adenocarcinoma areas].
OBJECTIVE: The association of cystitis glandularis with primary bladder tumors is well known. A case of cystitis glandularis progressing to transitional cell carcinoma is described and the literature briefly reviewed. METHODS/RESULTS: We report on a case of diffuse cystitis glandularis in whom progression to transitional cell carcinoma with areas of adenocarcinoma had been discovered. Treatment was by radical cystectomy with urinary diversion. CONCLUSION: Extensive and diffuse cystitis glandularis can be a potentially malignant lesion. Patients with diffuse cystitis glandularis should have a regular cystoscopic follow-up for early detection of progression to a bladder tumor.

[Intrascrotal aggressive angiomyxoma].
OBJECTIVE: To describe a case of aggressive scrotal angiomyxoma in a 55-year old man. METHODS: Ultrasound examination revealed a tumor on the scrotum. Surgical resection and histopathological study of the tumor was performed. The literature is briefly reviewed. RESULTS: Pathological analysis disclosed spindle-shaped neoplastic cells widely separated by a myxoid stroma rich in collagen fibers and prominent irregular-shaped blood vessels. Immunohistochemically, the stromal cells stained consistently for vimentin but not for desmin or S-100 protein. The patient had no symptom or signs of systemic disease and remains symptom-free 15 months later. CONCLUSIONS: Aggressive angiomyxoma is a rare condition that can be successfully treated surgically and has a great tendency to local recurrence.

[Submucous urethral angioma].
OBJECTIVES: Urethral hemangioma is a rare benign vascular tumor. The clinical features of this tumor type and the therapeutic options are discussed. METHODS/RESULTS: We report on a 55-year-old male with urethral hemangioma who consulted for urethral hemorrhage. CONCLUSIONS: To our knowledge, approximately 40 cases of this rare tumor type have been reported in the literature. Urethroscopy is the best diagnostic procedure. Treatment depends on tumor site, size and number. Transurethral resection of the tumor, urethrectomy, arterial embolization, radiotherapy or ablation with Nd:YAG laser can be utilized.

[Bladder compression caused by hip prosthesis displacement].
Case report of one patient with extrinsic vesical compression secondary to a displaced hip prosthesis. Interesting case due to increasing hip prosthesis surgery over the last few years involving, although not frequently, ureteral and vesical injuries of varying consideration which require early diagnosis and management.

[Vesico-umbilical fistula. Occurrence in an adult].
Vesicoumbilical fistula in the adult male basically results from repermeability of the urachus obliterated by an uncompensated vesicoprostatic obstruction. The passage of urine through the umbilicus is practically pathognomonic and the definitive diagnosis is made by IVP and cystourethrography. It is a relatively benign pathology with a good prognosis following surgical treatment. Herein we report a case of vesicoumbilical fistula in an adult male with a previous history of prostatic syndrome and chronic urinary retention, resulting in repermeability of the urachus.

[Bladder endometriosis simulating a bladder tumor].
Endometriosis is relatively frequent in females of menstrual age and consists in the appearance of active endometrial tissue at sites other than the uterine cavity (genital system or adjacent organs). Endometrial tissue has been described to colonize the urinary system, particularly the urinary bladder. The most common clinical features of vesical endometriosis are urgency and frequency, hypogastric pain and hematuria. We report on a case of vesical endometriosis whose presenting features were urgency and urinary incontinence. The urological work up disclosed a solid vesical mass. Cystoscopy was highly suggestive of endometrial submucosa formation which was confirmed by TUR.

Local hyperthermia in the treatment of benign prostatic hyperplasia. Assessment of 100 patients.
This study includes our first 100 patients who received local prostatic hyperthermia treatment for benign prostatic hyperplasia. Subjective symptoms such as nycturia, stream, urgency, and objective facts like urine flow and postmicturition residue were monitored before treatment and 3 months after. The clinical (subjective) symptoms improved in 76 patients. Urinary flow increased in 63 patients, and the postmicturition urinary residue decreased in 32 patients. We were able to show that local prostatic hyperthermia is a valid option for the treatment of benign prostatic hyperplasia although it is still too early to assess the long-term results.

[Rupture of the corpora cavernosa. Evaluation of 5 cases].
Five cases of fracture of penis with a mean follow-up of 52 months are described. Four underwent early surgical treatment and one was treated conservatively. This latter case developed penile curvature from fibrosis. The literature is reviewed with special reference to treatment. Like most of the authors, we advocate early surgical management as the treatment of choice for rupture of the corpora cavernosa.

[Technical modification in the surgical treatment of curvature of the penis].
Congenital curvature of the penis without hypospadias is not an uncommon condition whose treatment is by surgery. We report on 10 cases with congenital penile curvature submitted to the Nesbit procedure using our modified approach, which has achieved good results.

Leiomyomatous renal hamartoma in an adult.
In 1967, Bolande coined the term, congenital mesoblastic nephroma, in relation to a rare benign kidney tumor which is mainly found in infancy and that can be misdiagnosed clinically as a Wilm's tumor. It has been called renal fetal hamartoma, leiomyomatous hamartoma and renal leiomyoma. Four cases have been described in adults previously and here we report a new case.

[Calcification of a double-J ureteral catheter].
Two cases of stone formation on double J ureteral catheter are described. Resolution was achieved by ESWL in one and by simple endoscopic removal in the other case with calcification in the distal J. The appearance of calcareous encrustation is frequent and depends on various factors especially the length of time the catheter is left indwelling, urinary stasis and infection. The efficacy of extracorporeal lithotripsy in resolving this complication is discussed.

[New therapeutic alternative for complex renal lithiasis].
The combination of percutaneous nephrolitotomy and renal extracorporeal litothricy, is currently considered to be the best choice for the treatment of complex renal lithiasis. This procedure, however, quite frequently needs the use of adjuvant maneouvers (urethroscopy, catheterization, large number of sessions, etc.), and there is a considerable proportion of residual lithiasis. We present here our series using a new therapeutic sequence: first, we perform extracorporeal litothricy (ESWL) of calices not accessible to the nephroscope, followed by percutaneous nephrolitotomy which has revealed to be a simplification of the percutaneous surgical technique since it decreases the movements of the nephroscope and the use of ultrasounds. Calyceal lithiasis previously fragmented are then extracted through the nephrostomic channel and so no lithiatic paths are induced, the percentage of residual lithiasis being also lower.

[Early calculogenesis caused by ureolytic infection of the double-J ureteral catheter].
Stone formation in the double J ureteral catheter is an uncommon complication that generally appears in patients that are predisposed to stone formation and persistent infection of the urinary tract. We report on a 29-year-old female patient in whom stone formation was observed in both ends of the catheter, less than 3 months after it had been placed. Urine culture was positive for P. mirabilis. Percutaneous nephrolithotomy was warranted in the treatment of the pyelic stone and for removal of the double J catheter. We underscore the importance of doing urine cultures and radiologic control in this patient group and shortening the time the catheter is left indwelling.
