ABSTRACT

ABSTRACT Objective To evaluate the effectiveness and outcomes of endovascular treatment of TRAS with PTA. Materials and Methods We searched our prospectively collected database looking at cases of TRAS between January 2005-December 2011. CCT was the gold-standart for diagnosis of TRAS. Parameters analysed comprised technical aspects, arterial blood pressure variation, and renal function. A minimum follow-up of 24 months was considered. Results Of the 2221 renal transplants performed in the selected period, 22 (0.9%) patients were identified with TRAS. Fourteen (63.6%) were male and mean age was 377±14.8years (12-69). Kidney graft was from deceased donnors in 20 (80%) cases. On doppler evaluation, mean blood flow speed after transplantation, at TRAS diagnosis and after TAP was 210.6±99.5, 417±122.7 and 182.5±81.6mL/sec, respectively (p<0.001). For SBP and DBP, there was a significant difference between between pre-intervention and all post-treatment time points (p<0.001). After 1 month of the procedure, there was stabilization of the Cr level with a significant difference between mean Cr levels along time (p<0.001). After a mean follow-up of 16±4.2 (3-24) months, overall success rate was 100%. Conclusions Endovascular treatment with PTA/stenting is a safe and effective option for managing TRAS, ensuring the functionality of the graft and normalization of blood pressure and renal function.

ABSTRACT

Objectives: The aim of this study was to compare the results of laparoscopic donor nephrectomy with open donor nephrectomy. Methods: A non-randomized prospective analysis was conducted of living donor kidney transplantations (118 open donor nephrectomies; 57 laparoscopic donor nephrectomies) between January 2005 and December 2007 in the Kidney Transplantation Unit of Hospital das Clínicas of Faculdade de Medicina of the Universidade de São Paulo. Results: Mean donor operative time, mean donor hospital stay, mean postoperative creatinine values, and rates of complications and graft survival were similar for both groups. A significant statistical difference in warm ischemia time was observed between the open donor nephrectomy and laparoscopic donor nephrectomy groups (p < 0.001). There was only one conversion in the laparoscopic donor nephrectomy group. Conclusions: Laparoscopic donor nephrectomy is a safe procedure for a donor nephrectomy, comparable to an open procedure with similar results despite a longer warm ischemia time.


Objetivos: O objetivo deste estudo foi comparar a nefrectomia radical laparoscópica e a nefrectomia subcostal do doador. Métodos: Foi realizado um estudo prospectivo e não randomizado dos pacientes submetidos entre Janeiro 2005 e Dezembro 2007 a nefrectomia para doação renal na Unidade de Transplante Renal do Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo (118 casos de nefrectomia subcostal do doador; 57 casos de nefrectomia radical laparoscópica). Resultados: Tempo cirúrgico, tempo de internação hospitalar do doador, creatinina sérica pós-transplante e taxas de complicação e da sobrevida do rim transplantado foram similares para ambos os grupos. Foi encontrada uma diferença estatisticamente significante no tempo de isquemia quente (p < 0,001). Houve somente uma conversão no grupo submetido a nefrectomia laparoscópica. Conclusões: A nefrectomia laparoscópica do doador é procedimento seguro para doação renal e com resultados similares à nefrectomia subcostal, apesar de maior tempo de isquemia quente.

ABSTRACT

OBJECTIVE: The aim of this study was to determine the incidence of asymptomatic, histologically proven prostatitis in men with symptoms of benign prostate hyperplasia and to observe the correlation between asymptomatic prostatitis and prostate specific antigen (PSA) density. INTRODUCTION: The incidence of type IV prostatitis is unknown. There is a tendency to correlate the presence of inflammatory prostatitis with an elevation of PSA. MATERIALS AND METHODS: From August 2000 to January 2006, 183 patients who underwent surgical treatment for benign prostate hyperplasia as a result of obstructive or irritative symptoms were prospectively studied. In accordance with the histology findings, these patients were divided into two groups: group I included patients with the presence of histological prostatitis and group II included patients with the absence of histological prostatitis. The mean PSA densities were compared. RESULTS: Histological evidence of prostatitis was observed in 145 patients. In this group, the mean PSA density was 0.136 ± 0.095. In 38 cases, there was no evidence of inflammation upon histological examination of the surgical samples. In these 38 cases, the mean PSA density was 0.126 ± 0.129. No statistically significant differences were detected between the two groups; the p-value is 0.124. CONCLUSION: Abnormal PSA density should not be attributed to the inflammatory prostatitis process.

ABSTRACT

CONTEXT: Ureteral fibroepithelial polyps are rare benign nonepithelial tumors, and less than 200 cases have been reported in the literature. We report on a pregnant patient with ureteral fibroepithelial polyps that were successfully treated with laparotomy. CASE REPORT: A 23-year-old pregnant woman presented with a three-month history of intermittent lumbar pain of low intensity. Abdominal ultrasonography showed that she was 13 weeks pregnant and found severe left-side ureterohydronephrosis and a heterogeneous solid mass measuring 11 x 8 x 7 centimeters in the middle portion of the ureteral topography. The investigation was complemented with magnetic resonance imaging, which confirmed the previous findings. Nephroureterectomy was performed without complications. The specimen revealed three solid tumors in the ureter, of which the largest was around eight centimeters in length. The anatomopathological report confirmed that they were fibroepithelial tumors without malignant components.


CONTEXTO: Pólipos fibroepiteliais de ureter são tumores não-epiteliais benignos raros, e menos de 200 casos foram relatados na literatura. Nós reportamos o caso de uma mulher grávida com pólipos fibroelitelial ureteral que foram tratados com sucesso por laparotomia. RELATO DE CASO: Mulher de 23 anos de idade, grávida, apresentava história de dor lombar intermitente de baixa intensidade há três meses. Ultra-sonografia abdominal revelou gravidez de 13 semanas, ureterohidronefrose grave à esquerda e massa sólida heterogênea medindo 11 x 8 x 7 cm na porção média da topografia ureteral. A investigação foi complementada com ressonância magnética, que confirmou os achados. Foi realizada nefroureterectomia sem complicações. A peça revelou três tumores sólidos em ureter, o maior apresentando aproximadamente oito centímetros longitudinalmente. O relatório anatomopatológico confirmou tumor fibroepitelial sem componentes de malignidade.

ABSTRACT

Foram realizadas 100 biópsias de enxertos renais onde foram colhidos fragmentos de segmento superior e inferior. Em 70 casos (70 por cento) foi obtido material representativo para análise. Houve diferenças histológicas com implicações em diferentes recomendações terapêuticas em 13 (18,5 por cento) casos. O material foi revisto de maneira randomizada com confirmação dos resultados. Houve boa concordância diagnóstica entre achados de nefrotoxicidade (kappa = 0,631) e nefropatia crônica do enxerto (kappa = 0,624) e concordância marginal para rejeição aguda (kappa = 0,426). Houve hematúria.com necessidade de sondagem para evacuação de coágulos em 3 casos. /One hundred percutaneous biopsies were performed on kidney allografts and samples were collected from the upper and lower poles. Adequate specimens for analysis were obtained from both kidney poles from 70 per cent of the procedures. In 18,5 per cent (13 cases) there were histopathological differences that affected treatment recommendations. A randomized review was made and the results were confirmed.There was a good concordance for drug nephrotoxicity (kappa = 0,631) and chronic allograft nephropathy (kappa = 0,624) and a marginal correlation for acute rejection (kappa = 0,426). The only major complication was the gross hematuria which occurred in three procedures...

ABSTRACT

Foram analisados retrospectivamente 163 pacientes admitidos em nosso serviço de pronto-socorro vítimas de trauma renal fechado, enfatizando-se a abordagem diagnóstica e terapêutica dos mesmos. Dos 163 pacientes admitidos, 85 (52 porcento) foram encaminhados diretamente ao centro cirúrgico devido a presença de choque hipovolêmico, hemoperitônio ou lesöes associadas. Setenta e oito pacientes (48 porcento) foram investigados radiologicamente sendo que destes, 22 (28 porcento) foram tratados através de procedimento cirúrgico. Foram comparados ainda a sensibilidade e a especificidade dos exames radiológicos através do grupo de 22 pacientes investigados radiologicamente e submetidos a cirurgia. A tomografia computadorizada se mostrou ser exame mais sensível e específico, seguido da urografia excretora. Foram ainda revisadas as complicaçöes observadas entre os pacientes tratados conservadoramente, segundo a lesäo radiológica diagnosticada. O maior índice de complicaçöes ocorreu quando se observou fratura renal envolvendo vias excretoras
