[Association of renal carcinoma and the exposure to ionizing radiation after the Chernobyl accident].

After the nuclear accident of Chernobyl, in the population of zones contaminated the malignant renal tumors was increased from 4.7 to 7.5 per 100,000 of total population. Cesium 137 (137Cs) constitutes 80-90% of the internal exposure of these people as well as eliminated through kidneys becomes an important risk factor. We present a case of a patient, residing in radiocontamined area, who consulted for abdominal pain and left flank mass. We review relevant literature and the management of these patients.

[Encrusted pyelitis. Lithiasic disease with infectious etiology].

We report on two new cases of encrusted pielitis, a lithiasic disease of infectious ethiology--Corynebacterium of D group-. The clinic diagnostic is difficult and this disease develops in immunosuppressed patients, mainly in renal transplanted ones. One of our two cases is diagnosed in a patient with a transplanted kidney and the other one develops the disease within her native kidneys. We remark on the clinic features and therapeutic options.

[Pneumocysts, unusual infective complication in diabetics].

We report on a case of fully gas-filled bladder with no evidence of intramural gas, fistula between bladder and gastrointestinal tract or instrumentation. The patient is diagnosed of a diabetic neurogenic bladder. We comment the causes of this rare finding and its relation with emphysematous cystitis.

[Clinico-pathologic differences between bladder neoplasm with low malignant potential and low-grade carcinoma].

OBJECTIVE: To determine if the morphologic subgrouping of grade I bladder tumors between papillary neoplasm of low malignant potential and low grade papillary carcinoma is of clinical and survival value. MATERIAL AND METHODS: All 257 consecutive patients diagnosed of superficial bladder cancer between 1990 and 1995 in HU Reina Sofia of Cordoba were reviewed and further reclassified according to WHO/ISUP consensus classification of urothelial neoplasms of the bladder. Of the tumors 12 were urothelial papilloma, 51 were papillary neoplasm of low malignant potential, 43 were low grade papillary carcinoma Ta, 65 were low grade papillary carcinoma T1 and 37 were high grade papillary carcinoma. Eleven patients were reevaluated as T2 tumors and 38 (14.8%) were lost of control. All patients were reviewed with a follow-up at least of 5 years. We compare the results between groups with Fisher test and the risk factors for recurrence and progression are analyzed by multivariate analysis (Odds ratio). The survival function was calculated using Kaplan-Meier estimates and compared with the log-rank test. RESULTS: There are no differences between groups respect the age or sex distribution. The differences in the multiplicity are not significant and only the mean size is higher in papillary low grade carcinoma. About the risk factors for recurrence and progression of the disease, only is significative the tumor size. Rarely, the use of chemotherapy seems to play a role in the recurrence. There are no differences in recurrence and progression between the groups, although the percentages are always higher in the papillary low grade carcinoma group. CONCLUSIONS: There are enough clinical differences between the two groups and we consider them as distinct pathologic entities. Only the higher tumoral size is prognostic factor in each group. We think that the use of chemotherapy must be avoided in this low grade bladder tumors.

[Cryptorchism and testicular cancer].

OBJECTIVE: This report insists on the higher risk of testicular cancer in cryptorchidism and indicates the more adequate management of this pathology. METHODS/RESULTS: We report a 27 years old patient with history of cryptorchidism, diagnosed of abdominal tumor in urgency. This tumor was a seminoma in intrapelvic testicle. CONCLUSIONS: The risk of developing testicular cancer in cryptorchidism is 3 to 10 times greater than in a patient with normally descended testes, and orchiopexy does not prevent the risk of malignancy. We underscore the need to follow these patients closely and recommend the orchiectomy in postpubertal patients.

[Renal elimination of contrast after retrograde urethrocystography].

We describe a case report in which is shown an extensive extravasation of contrast media from urethra lumen following a retrograde urethrocystography. It is shown filling of cavernous system and, at once, iliac vessels and inferior cava. Later X ray plates demonstrates entire collecting system due to the renal contrast excretion.

[Incidence of high grade prostatic intraepithelial neoplasia in urologic practice].

High grade (PIN AG) intraepithelial neoplasia of the prostate is a likely precursor of prostate adenocarcinoma (PA) because of their association. Since the risk to suffer PA increases in patients with no previous PIN AG, its finding requires an arduous search for PA. This paper reviews the incidence of PIN AG in 499 histological studies in prostate transrectal biopsies, prostate TUR and adenomectomy specimens and radical prostatectomy (RP) sections. Evaluation of data obtained, type of presentation and association to prostate carcinoma, indicating the approach taken in the various cases.

[Wolfram syndrome. Urologic implications].

OBJECTIVES: We report on four new cases of Wolfram's Syndrome. We emphasize in urological aspects of this disease. PATIENTS AND METHODS: Three male siblings. The other patient is also a male, without familiar relation with the other ones. All four patients presents different levels of urological alterations, mainly urinary collecting system dilation and decrease in detrusor muscle contractility. CONCLUSIONS: Urological findings are cardinal aspects in Wolfram syndrome. Due to its high frequency and prognostic value in natural history of disease. Urological disease seems to be within a systemic neurological tissues affectation of etiology that remains unknown.

[Malignant fibrohistiocytoma of the bladder].

We report on new case of a rare vesical tumour. We result the importance of immunohistochemistry and ultrastructural study to support the diagnosis of malignant fibrous histiocytoma of the urinary bladder. There has been described another 16 cases of this tumour in the literature, however, only four of them -five with ours- reports an extensive immunohistochemical and ultrastructural study. The rarity of vesical localization of this tumour may delay its diagnosis. It must be supported by a immunohistochemistry and/or ultrastructural study, in order to differentiate from other tumours with fibrohistiocytoma-like pattern: leiomyosarcoma and sarcomatoid carcinoma of the bladder. After radical removal of tumour, adjuvant therapy is recommended both systemic chemotherapy and local radiotherapy, although survival rates are over 5.3 months after first therapeutical actuation.
