Objective: To compare the morbimortality in the treatment of the renal tumors with and without presurgical embolization of the renal artery. Material and methods: This was an observational, retrospective, crosssectional and comparative study in the period from 01/01/2000 to 31/03/2007, carried out at the National Medical Center "La Raza" in Mexico City. Included for this study men and women from 18 to 90 years of age, with diagnosis of renal tumor in which radical nephrectomy was made. They were divided in two groups: group 1 those in which embolization of the renal artery was made previous to the surgery by the service of radiology and in the group 2 patients without embolization. Statistical analysis: Descriptive statistic. Results: In 121 patients with embolization of the renal artery, the ancestry and histological degree was not significantly representative, but dimensions and the pathological stage was statistically significant with transsurgical bleedding both with a p = 0.001. The survival was greater in those with embolization. Conclusions: The embolization of the renal artery is useful because it prolongs the survival of the patients and diminishes transsurgical bleedding in tumors of 9 cm or more and in advanced stages.

Objective: To determine the rates of complications and associated factors of percutaneous nephrolitothomy procedure. Materials and methods: Retrospective, descriptive, cross-sectional and observational study. 108 medical files from patients with percutaneous procedure from January 2000 to 2007 in the Department of Urology were checked. The rates of complications and associated factors of percutaneous nephrolitothomy procedure were captured. Results: We reviewed 108 procedures. 40 were male and 68 female. 37 (34.26%) was nephrolithiasis type III, 33 (30.56%) type I, 20 (18.52%) residual nephrolithiasis, 14 (12.96%) type II, 4 (3.7%) type IV. Hypertension, diabetes and renal failure were the most common illness in the group of patients. The hospital stay was 5.81 days. The mean operative time was 2.81 hours. 39 (36.11%) was the rate of general complication, and the most common complications were: fever 20 cases (18.52%), hematuria 13 (12.04%), 10 (9.26%) patients required transfusions. There was no statistical significance in terms of associated factors, and complications. The percentage of kidneys free from calculus was 41.67%. Conclusions: The percutaneous surgery, is one of the well-accepted procedures for the treatment of renal stones. There is low morbidity in this procedure. [ABSTRACT FROM AUTHOR]

Objective: Describe the nephrectomy prevalence due to kidney neoplasm and the age groups in the Urology Service of the Hospital de Especialidades of the Centro Medico "La Raza". Material and methods: Retrospective, descriptive and transversal study. We include patients with nephrectomy due to kidney neoplasm in the Hospital de Especialidades of the Centro Medico "La Raza" during the period 2000-2006. Results: 121 clinic histories were reviewed. The mean age was 65.7 years. The higher prevalence by year was 27.3% (2006). According to the UICC classification the frequency of stages by tomography was 20.7% for T2N0M0 (n = 5). Respect the surgical modality the frequency of the nephrectomy was 96.7% (n = 117) for radical and 3.3% (n = 4) for partial nephrectomy. Regarding to the surgical approach the open surgery was 93.4% (n = 113) and laparoscopic 6.6% (n = 0). The kidney neoplasm prevalence was benign in 2.5% (n = 3) and malignant in 97.5% (n = 118), of these 98.3% (n = 118) were localized in kidney parenchyma and 1.7% (n = 2) in the kidney pelvis. Histopathology more frequently found was clear cell carcinoma 81.8%. Conclusions: The nephrectomy prevalence by kidney neoplasm was 2.6%. The mean age risk is in the sixth decade of life. The most common technique actually used is by laparoscopy, and cancer histopathology more frequently found is clear cell carcinoma. [ABSTRACT FROM AUTHOR]

Objective: To determine if the postoperative Penrose drainage is a prognostic factor in developing bladder neck contracture in patients with radical retropubic prostatectomy . Material and Methods: Retrospective, descriptive and observative study. 80 medical files from patients with radical prostatectomy from 2004-2006 in La Raza National Medical Center were checked. The Penrose drainage from the first three postoperative days and the patients who developed bladder neck contracture were captured. Results: Bladder neck contracture was found with a 21.3% frequency. The Penrose drainage in patients who developed bladder neck contracture showed a mean of 1675.88 mL, and the mean for those who did not developed bladder neck contracture was 165.11 mL, with a 1,510 mL difference (p < 0.01). The analysis under de ROC curve showed that the bladder neck contracture can be predicted in 97.8% of the patients. The cut point was 232 ml with a 90% sensitivity and a 94% specificity. Conclusions: Bladder neck contracture in patients with radical prostatectomy was found with a frequency similar than those showed in other series. The developing of this postoperative complication can be predicted in 97.8% of the patients and by doing this we could give them an early treatment. [ABSTRACT FROM AUTHOR]

Objective: To compare the analgesic effect of the petroleum jelly and the lubricating jelly used as contact medium in patients with urolithiasis subjected to external shock wave lithotripsy. Material and methods: We select patients with urolithiasis that received treatment with external shock wave lithotripsy between march 2002 to may 2002; using lubricating jelly as contact medium in group A and petroleum jelly in group B, and being evaluated the pain perception by a visual pain score in each one of the groups. Results: 94 patients were studied, 46 in the group A and 48 in the group B, with a score average in the visual pain score of 7.43 (± 2.09) in the group A (p = 0.122), and 7.06 (± 1.19) in the group B (p = 0.001). The average of intensity of the shock wave was of 51.06% (± 15.88) in the group A (p = 0.0014), and 59.22% (± 14.13) in the group B (p = 0.106). Conclusions: This study demonstrates that the petroleum jelly used as contact medium during the extracorporeal shock wave lithotripsy, presents a significantly smaller score in the visual pain score in comparison with the lubricating jelly; also, the patients with lubricating jelly reach a shock wave intensity significantly smaller in comparison with petroleum jelly.

Prostate cancer (PC) is a common malignant neoplasia in males over 50 years. The serum level of prostate specific antigen (PSA) is a tool in the diagnosis of PC and benign prostatic hyperplasia patients that improves the efficiency obtained with the digital rectal examination. The use of PSA increases the detection rates of organ-confined PC. The PSA must be requested by the primary care physician in male population over 45 years and if the result is above the normal levels, the patient must be send to an urologist. [ABSTRACT FROM AUTHOR]
