The value of intravenous urography in patients with prostatism was retrospectively evaluated. One thousand four hundred ninety five intravenous urograms of male patients referred by the department of urology were reviewed. Based on the clinical information, only patients with complaints of prostatism as a single symptom were selected. Patients with associated symptoms (i.e. hematuria, urinary infection) were excluded. Forty seven patients could be included based on these criteria. In 29 of 47 cases (61.7%) no abnormalities were found. Abnormalities found in 18 cases included dilatation of the excretory system, urinary calculi, congenital anomaly, acquired small kidney, renal cysts and retroperitoneal fibrosis. In 5 cases (10.1%) the intravenous urography necessitated further treatment and/or follow up. In 3.1% prostatism was the indication for the examination. The number of relevant abnormalities at intravenous urography performed for prostatism is low and this is in accordance with results reported in literature. These results provide further evidence for the continuously changing indications for intravenous urography.

Objective: To explore the clinical value of combining split-bolus contrast injection with dual-energy CT(DECT) scanning technology in pediatric computed tomography urography (CTU) imaging.
Methods: A total of 128 children aged 0-17 years were prospectively selected and randomly assigned to three groups: A, B, and C. For Group A, a high-pitch flash mode was employed, where a single bolus of contrast agent was followed by four-phase scanning (noncontrast, cortex, medulla, and excretory phases).

Despite the high incidence of bladder cancer (it represents the 7th most common cancer in males), EAU guidelines do not recommend any technique for screening and prevention, whereas the main diagnostic tools remain computed tomography urography (CTU), cytology, and cystoscopy. Unfortunately, these gold-standard modalities are mainly characterized by low sensitivity and accuracy. To minimize the limitations and increase the detection rates of urothelial cancer, several technologies have been developed.

The different causes of hematuria depend largely on age, gender and clinical context. Macrohematuria should always be investigated using cystoscopy and advanced imaging (CT/MRI with urographic phase). The most common differential diagnoses of macrohematuria include urinary tract infection, stones and urothelial carcinoma.

Upper tract urothelial carcinoma (UTUC) is a rare and challenging subset of the more frequently encountered urothelial carcinomas (UCs), comprising roughly 5-7% of all UCs and less than 10% of all renal tumors. Hematuria is a common presenting symptom in the emergency setting, often prompting imaging to rule out serious etiologies, with UTUC especially posing as a diagnostic challenge. These UTUC lesions of the kidney and ureter are often small, mimicking other pathologies, and are more aggressive than typical UC of the bladder, emphasizing the importance of timely and accurate diagnosis.
