“…IVU tomography can enhance the diagnostic yield but again it relies on adequate contrast excretion by the kidney. Also, in cases of potential allergies to contrast media, reduced excretory renal function and in children as well as pregnant women, an IVU is contraindicated [16][17][18] .…”

Objectives: We reviewed the data of patients with upper urinary tract (UUT) tumors to evaluate the effectiveness of diagnostic procedures. Methods: This retrospective study evaluated tumor characteristics, imaging procedures, epidemiological and follow-up data of 113 patients. We analyzed the importance of non-invasive and endoscopic diagnosis in addition to imaging as well as the influence of stage and grade on recurrence rate. Results: Most tumors were urothelial carcinomas (92.9%). The cardinal symptoms were hematuria (40.7%), flank pain (2.7%), and urinary obstruction (14.2%). Forty-seven patients received intravenous urograms (IVUs), 57 retrograde ureteropyelography (RUP), 89 CTs, 6 an MRI. The correct positive tumor identification was reached by IVU in 27/47 patients, by RUP in 50/57, by CT in 74/89, and by MRI in 3/6 patients representing sensitivities of 57.4% (IVU), 87.7% (RUP), 83.1% (CT), and 50% (MRI). Sixty-four patients had urine cytology, which was correctly positive in 60.9% and 56 had a diagnostic ureterorenoscopy, which was correctly positive in 83.9%. During follow-up more than 20% of patients developed a recurrence. Conclusion: In patients with hematuria and flank pain, UUT must be considered a differential diagnosis. UUT to the extent of 76.6% showed more invasive growth (>Ta). Thus, rapid and efficient diagnosis based primarily on imaging is required. Contrast CT scan seems to be the imaging modality with the best performance. However, often only a combination of diagnostic procedures gives a certain diagnosis. Due to the high recurrence rate, close follow-up is needed.

CT-Urographie bei Frauen mit primären oder rezidivierenden Beckentumoren

Malignant tumors of the female pelvis account for 12-13% of newly diagnosed solid neoplasms among women in the USA and Germany. German guidelines advocate diagnostic imaging for local recurrence and metastasis while there are no recommendations for primary tumors. As excretory urography has been replaced by the excretory phase of computed tomography urography (CTU) in many institutions, two independent observers retrospectively evaluated CTUs of primary or recurrent female pelvic tumors to rule out associations between CTU findings and subsequent urologic measures. Among 31 CTUs of 27 women (age 29-84 years, mean 57 years) with 15 primary and 13 recurrent tumors, 83-100% of unremarkable proximal, middle and distal ureter segments were completely delineated in the excretory phase (delay 6-29 min, mean 16 min). The most common pathological findings included distal ureter obstruction (n=19, 61%), bladder compression (n=13, 42%) and bladder invasion (n=8, 26%). Out of 20 pathologically altered urinary tracts 8 were subsequently subjected to urologic measures (2-tailed Fisher exact test, p=0.0215) but none of the 10 unremarkable urinary tracts were treated. It appears that CTU is a sensible pre-therapeutic test for the urinary tract for primary and recurrent female pelvic tumors.
