[Mumps orchitis; review of 8 cases].

OBJECTIVE: To determine the incidence of mumps orchitis in young males in the area of El Bierzo (Ponferrada, Spain) and the complications arising from this condition. METHODS: The cases of mumps orchitis referred by the primary care services to the emergency services of Hospital del Bierzo referral center were reviewed. We analyzed patient age, unilateral or bilateral testicular involvement, whether the patients had been vaccinated against mumps and the changes observed in the semen analysis. RESULTS: The diagnosis of mumps orchitis was confirmed in 8 patients, aged 15 to 19 years. Two patients had bilateral testicular involvement. Seven patients had not been vaccinated against parotiditis. Three patients had oligoasthenospermia and are currently being followed at the Urology services. CONCLUSIONS: The utility of large scale vaccination against mumps is emphasized. Long-term follow-up is recommended for all patients with abnormal semen analysis, particularly those with bilateral testicular involvement, since they may develop oligoasthernospermia several years after the infection or improve with item. A high incidence of mumps orchitis was found for this 12-month study period.

[Multilocational cystic nephroma. Review of a case with reference to echographically observed changes].

OBJECTIVE: To describe an additional case of multilocular cystic nephroma, with special reference to the sonographic features of a renal cystic lesion. METHODS: The clinical and radiological features of a kidney tumor in a 61-year-old female patient were retrospectively analyzed. RESULTS: The preoperative diagnosis was that of a complex multicystic renal mass suggestive of a renal carcinoma. Radical nephrectomy was performed; histopathological analysis of the surgical specimen disclosed a multilocular cystic nephroma. An ultrasound scan 18 months earlier had demonstrated a simple renal cyst in the same site. CONCLUSIONS: Multilocular cystic nephroma is a tumor that is difficult to diagnose preoperatively. Making an accurate differential diagnosis is of interest, since it will permit conservative treatment. The case described herein supports the hypothesis with regard to the pathogenesis of this lesion, since it had previously showed sonographic features of a simple renal cyst.

[Suprarenal cysts].

OBJECTIVE: To emphasize that adrenal cysts are an uncommon finding and in most cases incidentally discovered during evaluation for nonspecific abdominal pain or even at outopsy. METHODS: We report a case of a non-hypers-creting right adrenal cyst in a middle-aged woman. RESULTS: A complete hormone, radiological and sometimes isotopic evaluation are required to make an accurate diagnosis and to determine the adequate treatment. CONCLUSION: Surgical resection is usually prompted by an inaccurate diagnosis and failed conservative treatments.

[Transitional cell bladder carcinoma in patients younger than 40 years of age].

OBJECTIVE: The clinical and pathological characteristics of bladder cancer in young patients were analyzed to determine if patients with bladder cancer under the age of 30 have a better prognosis than older adults and if transitional cell carcinoma of the bladder in patients aged 30 to 40 years has a similar behaviour to that observed in the higher risk population. METHODS: A retrospective review of transitional cell carcinoma of the bladder in patients less than 40 years old that had been treated between January, 1993 to August, 1997 was undertaken. RESULTS: We found 8 patients (5 men and 3 women) with urothelial tumor, accounting for an incidence of 4%. Four cases were diagnosed and staged TaG1, 2 T1G1 and 2 T1G2. Recurrence was observed in one case (12.5%) and progression in none. CONCLUSIONS: Transitional cell carcinoma of the bladder in patients under the age of 40 is usually associated with low grade and low stage tumors. The foregoing finding is certainly observed in those aged less than 30 years old. Bladder cancer is relatively rare in this age group, although we have found a higher incidence than that reported elsewhere. Treatment and follow-up depend on tumor grade and stage, regardless of age.

[Perineal tuberculous abscess. Presentation of a clinical case].

OBJECTIVE: To describe a case of perineal abscess caused by Koch's bacillus in a patient with a history of bladder tumor. METHODS/RESULTS: The patient described herein had consulted at the emergency services for perineal abscess. He had previously undergone transurethral resection of a bladder tumor and had received prophylactic intravesical BCG instillation thereafter. A culture of the exudate led to the diagnosis of tuberculosis, with no microbiological relation to BCG therapy. During the course of the disease, the patient developed a urethrocutaneous fistula which resolved after specific medical treatment. CONCLUSIONS: In a patient with clinical features of tuberculosis and a recent history of exposure to BCG, it does not necessarily follow that this bacillus is the cause of the tuberculosis. Furthermore, not all tuberculous fistulas progress to chronicity or require surgical treatment.

[Bilateral obstructive uropathy secondary to encrusted cystitis. Report of a case].

OBJECTIVES: Bilateral urinary obstruction is usually secondary to tumors or bilateral lithiasis. A rare case of encrusted cystitis causing bilateral hydronephrosis is described. METHODS/RESULTS: A 70-year-old woman presented with severe dysuria and vesical tenesmus. She had previously undergone pelvic surgery and received radiotherapy for a gynecological tumor. She was diagnosed as having encrusted cystitis. Treatment with urinary acidification and antibiotics achieved complete radiological and functional recovery. CONCLUSIONS: Some cases of urinary obstruction can be managed conservatively. An accurate diagnosis is necessary to avoid surgery in these cases.

[Adenomatoid tumor of the epididymis. Report of a new case].

OBJECTIVES: To report on an additional case of adenomatoid tumor of the right epididymis, a rare benign intrascrotal mass. METHODS/RESULTS: A 41-year-old man consulted for severe scrotal pain. Physical examination disclosed a mass in the right epididymis which was confirmed by scrotal ultrasound. A right orchidectomy was performed. Histological analysis of the surgical specimen disclosed a benign adenomatoid tumor of the epididymis. CONCLUSIONS: Although most scrotal solid masses are malignant tumors, those arising in the epididymis are frequently benign; therefore a conservative approach is recommended.

[Pseudo-tuberculous pyelonephritis].

We report on a 67-year-old woman with caseating granulomatous pyelonephritis associated with nephrolithiasis. Caseating granulomas resembling renal tuberculosis were observed in the renal parenchyma, but no TB or other microorganisms were detected in the renal tissue or urine cultures. To our knowledge, this is the second case reported in the literature.

[Transitional carcinoma of the prostate. Report of a case treated with chemotherapy].

A case of transitional cell carcinoma of the prostate is described which had been diagnosed following TUR of the prostate due to cervico-prostatic obstruction. Subsequent cystoscopic and cytological controls, as well as multiple bladder biopsies have discarded a concomitant urothelial tumor. We underscore the rarity of transitional cell tumor of the prostate, its response to chemotherapy and the possibility of suspecting this tumor type when there is massive invasion of the prostate following TUR.

[Erythrocytosis and renal adenocarcinoma].

Contribution of one left renal adenocarcinoma in a 54-year old women, where the initial data was the finding of erythrocytosis discovered during routine laboratory tests performed by her gynaecologist. Review of the diagnostic and therapeutic procedures followed in this case, establishing a differentiation between erythrocytosis and polyglobulia. Normalization of the hemogram following extended nephrectomy is emphasized. This case history is considered to be of interest due to its presentation pattern. Finally, we believe that faced to an erythrocytosis of unknown etiology, a renal tumoral disease, more specifically a renal adenocarcinoma, should be suspected.

[Vesico-uterine fistula].

We report a case of uterovesical fistula that had been diagnosed by cystoscopy, vaginoscopy and ultrasonography. Fistulorrhaphy via the transperitoneal transvesical approach resolved the passage of urine to the vagina. The decision to perform a conservative or more aggressive approach is determined by the site of the fistula.

[Prostatic syndrome and pleural effusion: are they different diseases?].

OBJECTIVE: To report an uncommon association of prostate and lung cancer. METHODS: The characteristics of both tumors, their association with tumors in other sites and the time of presentation are analyzed. RESULTS: Both tumors were in the advanced stages. Metastatic carcinoma of the prostate was discarded due to the form of presentation. CONCLUSIONS: Although the association of prostate and lung cancer is uncommon, the possibility of synchronous tumors should be considered in patients with urinary and pulmonary symptoms suggestive of neoplasm. It is important to determine if the lesion is a metastasis, since the prognosis depends on the second tumor.
