“…The absolute values of citrate, creatine and choline levels contribute in the identification of areas suspicious for malignancy and the choline-creatine/citrate ratio demonstrates equivalence with the Gleason score, allowing for a noninvasive selection of areas for prostate biopsy and evaluation of the tumor grade ( 21 , 22 ) . Thus, spectroscopy may be employed in the diagnosis of tumor recurrence, in patients treated by radiotherapy, cryotherapy or surgery ( 21 - 23 ) . The routine utilization of spectroscopy in the evaluation of other neoplasms is still questionable ( Figure 9 ).…”

In the investigation of tumors with conventional magnetic resonance imaging, both quantitative characteristics, such as size, edema, necrosis, and presence of metastases, and qualitative characteristics, such as contrast enhancement degree, are taken into consideration. However, changes in cell metabolism and tissue physiology which precede morphological changes cannot be detected by the conventional technique. The development of new magnetic resonance imaging techniques has enabled the functional assessment of the structures in order to obtain information on the different physiological processes of the tumor microenvironment, such as oxygenation levels, cellularity and vascularity. The detailed morphological study in association with the new functional imaging techniques allows for an appropriate approach to cancer patients, including the phases of diagnosis, staging, response evaluation and follow-up, with a positive impact on their quality of life and survival rate.

“…In spite of developments in different imaging diagnosis methods applied to evaluate pelvic diseases, the confirmation of prostate cancer diagnosis is still achieved by means of histological evaluation of specimens obtained by transrectal biopsy (5,6) , a procedure that is generally safe and well tolerated by patients. However, some studies have reported complication rates of up to 73%, as immediate and spontaneous resolution events are included (7) .…”

OBJETIVO: Avaliar a incidência de complicações pós-procedimento nos pacientes submetidos a biópsia prostática transretal guiada por ultrassom no setor de intervenção do Departamento de Diagnóstico por Imagem da Escola Paulista de Medicina - Universidade Federal de São Paulo. MATERIAIS E MÉTODOS: Foram avaliados, via contato telefônico, 132 pacientes submetidos a biópsia de próstata transretal guiada por ultrassom no período de abril/2011 a junho/2011, seguindo o protocolo padrão do nosso setor. RESULTADOS: As complicações pós-biópsia foram categorizadas em maiores e menores de acordo com a necessidade de avaliação médica adicional. Cinquenta e nove pacientes (61,8%) apresentaram complicações, e desses, grande parte (86,4%) apresentou sintomas leves e autolimitados, considerados menores. Oito pacientes (8,2%) apresentaram complicações maiores, sendo que apenas um deles necessitou de tratamento sob regime de internação hospitalar. A retenção urinária foi a complicação maior mais incidente no nosso estudo. CONCLUSÃO: Corroborando outros estudos da literatura, nosso trabalho demonstrou baixa prevalência de complicações maiores após a biópsia prostática transretal.
