[Xanthogranulomatous pyelonephritis in childhood. A case report].

Xanthogranulomatous pyelonephritis is an uncommon chronic inflammatory renal disorder. Most cases have been described in middle aged women and it is extremely rare in children. We report a case of a 4 year old girl who suffered from recurrent urinary tract infection and antibiotic therapy resistance. She had low growth-rate and palpable left renal mass on examination and was confirmed by radiological findings. We performed left kidney partial resection and then histological examination showed focal xanthogranulomatous pyelonephritis. The focal form of the disease may respond to antibiotic treatment although usually an enucleation or partial resection must be performed. In conclusion xanthogranulomatous pyelonephritis should be considered in the differential diagnosis of a renal mass and recurrent urinary tract infection in childhood.

[Adrenal metastases of Ewing's sarcoma. Report of one case].

Adrenal metastases are more frequent than primary adrenal carcinoma. The most frequent are, in this order: breast and lung cancer, stomach and kidney carcinomas, adrenal gland contralateral tumors and melanoma. Less frequent are tumours of the bladder, colon, esophagus, gall bladder, liver, pancreas, prostate, stomach and uterus. The rest of the tumours rarely spread toward adrenal glands. The metastases to the adrenal glands caused by sarcomas are rare and normally they happen in the contest of a massive metastases affecting several organs at the same time. We present a case of a patient affected by adrenal metastases of Ewing's sarcoma who has been referred to us for surgical treatment because it is a unique metastases (there is no sing of more illnesses in other organs at the time of the exploration).

[Transurethral prostatic resection with bipolar scalpel].

UNLABELLED: FUNDAMENTAL: [corrected] To show our initial experience in the TUR of prostate with bipolar axipolar bistoury. MATERIAL AND METHODS: Five patients with an average age of 72 years old, were operated between may and june 2002. They showed important increased in questionnaire symptoms (IPSS). The average ecographic volume has been 57.4 g. We employed Gyrus resector and physiological salt solution for continue irrigation. RESULTS: The average operative time was 70 minutes. None of the patients showed hyponatremia needed blood transfusion. In all the cases the sound was removed 48 hours after operation, one of them have urinary retention (UR) and need sound tow more days. Hospital stay was tree days except the patient how had UR. At 1 and 6 month there is improvement in the IPSS. CONCLUSIONS: TUR of prostate with bipolar axipolar bistoury can avoid the secondary effects of glicine and allows us to work with prostates of bigger volumes due to we have more time to do it. Nevertheless bigger and better studies are required to value the effectiveness of this new technology opposite the TUR of prostate with monopolar bistoury which keeps being the gold standard.

[Predictive model for prostate cancer in patients with biopsy indication].

OBJECTIVE: Attemp to determine the probability of developing prostate carcinoma taking into acc age, digital rectal examination and PSA once a transrectal biopsy has been indicated, so that both doctors and patients have mor information to face such pathology. MATERIAL AND METHODS: Retrospective study of 633 biopsies, taken into acc the patient's age, digital rectal examination, PSA level and histology. The data were included in a database created with Access and were put a logistic regression by mens the software program SPSS. RESULTS: Once the biopsy is indicated, digital rectal examination is the parameter offesing a higher discriminatory valuer with an odd ratio of 5.9 (CI 95%, 3.9-8.9). The mathematical model obtained shows a sensitivity level of 57% and a level of specificity of 84%. Pre-test probability is 36%, the probability post-test increasing up to 70%, and a negative predictive value of 77% and a positive predictive value of 67%. CONCLUSIONS: The mathematical model obtained individually determines the probability of suffering from prostatic carcinoma. Moreover, using this model the probabilities obtained re more precise than those derived from the fact of fulfilling the criteria for a prostatic biopsy. Once a biopsy is indicated, the rectal examination becomes the parameter with a higher predictive value of PC, irrespective of PSA and age. The PPV of the model is higher than of the PSA or the digital recta examination used separately.

[Value of post-miction residue after urethrocervicopexy. Prospective study].

OBJECTIVE: To demonstrate that a high post-micturitional residue after a colposuspension is not a success predictive factor in the incontinence surgery. METHODS: We designed two identical groups of work, with the only difference of a high post-micturitional residue in one of them after the surgery (< 100 cc), and we evaluated the surgical results, with a follow-up of one year. We considered fails the presence of losses related with stress. RESULTS: There were no significative differences in the number of the deliveries, age, weight, length or body mass index in both groups. There were significative differences in the permanence of the urethral catheter and residue of urine, p < 0.001. There were no differences in the number of success in both groups. CONCLUSION: A high post-micturitional residue after colposuspension is not an influent factor in the final result of surgery.

[Radical prostatectomy or radiotherapy? A qualitative structured review].

We performed a structured literature review to define de effectiveness of radical prostatectomy and external radiotherapy for treatment of localized prostate cancer. We identified 463 articles in MEDLINE for January 1990 through april 2000. As judged from our analysis, prostatectomy radical has marginal benefit in terms of supervivency and disease free respect to external radiotherapy with the same quality of life.

[Analysis of the reasons for non graft initial function in our series of the last eleven years].

UNLABELLED: FUNDAMENTAL: [corrected] To know which risk factor of delayed graft function in our patients. MATERIAL AND METHODS: We analyzed 469 transplants, 270 had good initial function and 199 had delayed function graft. Variables studies in booth groups were: age, sex and dead cause of donant, type of extraction and place were it was done, implantation side, vases multiple, isquemia times, age and receptor sex, HLA compatibility, retransplant, Ac Anti-VHC, PTH pretransplant, years in waiting list, hiperinmunization, number of transfusion, and type of inmunosupretion. RESULTS: Univariant study: significant differences were found in age and dead cause of donant, isquemia times, years in waiting list, hiperinmunization, number of transfusions, and HLA-B incompatibility. Multivariate study: we have significant differences in age of donant, could isquemia time, years in waiting list, cuadruple? Inmunosupretion. CONCLUSIONS: Results suggest to short could and revascularization isquemia time as possible, and use less nefrotoxic inmunosupretion pautes in high-risk patients.
