“…Compared to cystoscopy, which represents the gold standard in bladder cancer diagnosis, URO-CT is not a useful method in the identification of LTUC but is useful in follow-up and in muscle-invasive and metastatic bladder cancer to evaluate its extension [1,69], multiple high-risk tumors, or in the trigone vesica localization. On the other hand, CT urography is the most sensitive method for the identification of UTUC [70].…”

“…By accurately detecting and characterizing the wide variety of genitourinary disorders, such as renal stones or aberrant renal parenchyma and renal lesions, CT scanning can guide clinicians to the most suitable treatment [1]. However, there are some drawbacks to the use of traditional CT imaging techniques to assess urological disorders [2].…”

Dual-energy computed tomography (DECT) is a medical imaging technique that uses two different energy levels of X-rays to provide more detailed information about the composition of tissues and materials within the body. DECT technology is still relatively new but different applications have been developed for the urological field. For example, it can be used to analyze the composition of stones to determine whether they are likely to be made up of calcium oxalate, uric acid, or other minerals. This information can help guide treatment decisions, as different types of stones may require different approaches to treatment. The availability of iodine maps helps the differentiation between benign and malignant tumors of the urinary tract, including the bladder, kidneys, and ureters. The iodine maps generated by DECT can provide information on tumor vascularity, which can help in staging and determining the aggressiveness of the tumor. DECT can assess blood flow in the kidneys and detect vascular disorders such as renal artery stenosis or aneurysms. This can be critical for early detection and management of these disorders, which can reduce the risk of renal failure and improve outcomes. DECT is a valuable tool in the urological field that can provide clinicians with detailed and accurate information for the diagnosis and treatment planning of various urological conditions. In this narrative review, we propose an overview of the possible application of DECT in the field of urological diseases.

“…Regarding diagnostic management, US may be the first tool that should be utilized, showing hydronephrosis, the absence of ipsilateral ureteral jet, and ascites [ 68 ]. CT urography in the excretory phase is certainly more accurate in directly identifying any ureteral or bladder lesions, showing contrast medium extravasation associated with possible collection in the retroperitoneal or peritoneal space [ 69 , 70 ].…”

Rectal cancer (RC) is one of the deadliest malignancies worldwide. Surgery is the most common treatment for RC, performed in 63.2% of patients. The type of surgical approach chosen aims to achieve maximum residual function with the lowest risk of recurrence. The selection is made by a multidisciplinary team that assesses the characteristics of the patient and the tumor. Total mesorectal excision (TME), including both low anterior resection (LAR) and abdominoperineal resection (APR), is still the standard of care for RC. Radical surgery is burdened by a 31% rate of major complications (Clavien–Dindo grade 3–4), such as anastomotic leaks and a risk of a permanent stoma. In recent years, less-invasive techniques, such as local excision, have been tested. These additional procedures could mitigate the morbidity of rectal resection, while providing acceptable oncologic results. The “watch and wait” approach is not a globally accepted model of care but encouraging results on selected groups of patients make it a promising strategy. In this plethora of treatments, the radiologist is called upon to distinguish a physiological from a pathological postoperative finding. The aim of this narrative review is to identify the main post-surgical complications and the most effective imaging techniques.

Computed Tomography Urography: State of the Art and Beyond

Computed Tomography Urography (CTU) is a multiphase CT examination optimized for imaging kidneys, ureters, and bladder, complemented by post-contrast excretory phase imaging. Different protocols are available for contrast administration and image acquisition and timing, with different strengths and limits, mainly related to kidney enhancement, ureters distension and opacification, and radiation exposure. The availability of new reconstruction algorithms, such as iterative and deep-learning-based reconstruction has dramatically improved the image quality and reducing radiation exposure at the same time. Dual-Energy Computed Tomography also has an important role in this type of examination, with the possibility of renal stone characterization, the availability of synthetic unenhanced phases to reduce radiation dose, and the availability of iodine maps for a better interpretation of renal masses. We also describe the new artificial intelligence applications for CTU, focusing on radiomics to predict tumor grading and patients’ outcome for a personalized therapeutic approach. In this narrative review, we provide a comprehensive overview of CTU from the traditional to the newest acquisition techniques and reconstruction algorithms, and the possibility of advanced imaging interpretation to provide an up-to-date guide for radiologists who want to better comprehend this technique.
