RESUMO
INTRODUÇÃO E

OBJETIVOS:

Há controvérsias em relação à indicação e ao momento ideal de realização de derivação urinária em pacientes com obstrução ureteral secundária a neoplasias malignas avançadas. O objetivo do presente estudo foi identificar fatores relacionados ao mau prognóstico de pacientes com nefropatia obstrutiva maligna e criar um modelo de estratificação de risco desses pacientes, a fim de fornecer evidências para uma melhor decisão terapêutica.

MÉTODO:

Realizou-se estudo prospectivo com pacientes portadores de insuficiência renal obstrutiva por neoplasias pélvicas, acompanhados por um tempo mínimo de seis meses, tratados entre janeiro de 2009 à novembro de 2011. De um total de 340 pacientes submetidos à procedimentos de descompressão ureteral por catéter ureteral (CUR) ou nefrostomia percutânea (NPC), 208 foram incluídos no estudo por serem maiores de 18 anos, apresentarem obstrução ureteral secundária à neoplasias malignas, confirmada por tomografia computadorizada (TC) ou ultrassom (USG) e por terem realizado derivação urinária por catéter ureteral ou nefrostomia percutânea em nossa Instituição.

RESULTADOS:

A sobrevida média global foi de 144 dias, com mortalidade ao final do estudo de 164 pacientes (78.8%), sendo 44 (21.2%) durante a internação hospitalar. Não houve diferença significativa na sobrevida global entre os dois tipos de derivação urinária realizada (p = 0.216). Após análise univariada, a presença de qualquer sintoma (p = 0.014), derrame pleural (p = 0.015), grau de hidronefrose 1 e 2 (p = 0.001), Índice de Charlson >= 6 (p = 0.003), linfonodos retroperitoneais metastáticos (p = 0.002), linfonodos pélvicos metastáticos (p = 0.024), número de sítios relacionados à disseminação da doença >= 4 (p < 0.001), niveis séricos iniciais de uréia >= 80mg/dl (p = 0.01), sódio <= 138 mEq/L (p = 0.018) e albumina < 3.0 mg/dl (p = 0.035), diálise peri-operatória (p = 0.05) e índice de ECOG PS (Eastern Cooperative Oncology Group Performance Status)...
ABSTRACT
INTRODUCTION AND

OBJECTIVES:

There is a controversy regarding the decision to perform diversion procedures in patients with ureteral obstruction secondary to advanced malignancies. The goal of this study was to identify poor prognosis factors and to create a model to stratify patients with malignant obstructive nephropathy in order to provide evidence-based information for better treatment decisions.

METHODS:

A prospective study was performed from January 2009 to November 2011, with patients followed at least for 6 months. From 340 patients initially submitted to ureteral decompression procedures by ureteral stents or percutaneous nephrostomy, 208 were elected for the study because they were 18 years old or more and presented ureteric obstruction secondary to any type of malignancy, confirmed by computadorized tomography (CT) or ultrasound (US) and were submitted to urinary diversion by ureteral stents or percutaneous nephrostomy at our institution.

RESULTS:

The median survival for all patients was 144 days, with mortality at the end of study seen in 164 patients (78.8%) including 44 (21.2%) during hospitalization. There was no significant difference in overall survival between the two types of urinary diversion (p = 0.216). After univariated analysis the presence of any symptoms (p = 0.014), pleural effusion (p = 0.015), degree of hydronephrosis 1 and 2 (p = 0.001), Charlson Index >= 6 (p = 0.003), metastatic retroperitoneal lymph nodes (p = 0.002), metastatic pelvic lymph nodes (p = 0.024), number of sites related to dissemination >= 4 (p < 0.001), preoperative serum level urea >= 80mg/dl (p = 0.01), sodium <= 138mEq/L (p = 0.018), albumin < 3.0 mg/dl (p = 0.035), perioperative dyalisis (p = 0.05) and ECOG PS index >= 2 (p < 0.001) were associated to shorter mean survival. The multivariate Cox proportional hazards regression model revelead that only the number of sites related to malignant dissemination (4 or more) and the index of performance status of...
