Purpose To assess correlations between stone size/location and severity of secondary signs for ureteral obstruction. Methods Unenhanced multi-detector computed tomography examinations of 150 patients with acute renal colic were reviewed. Stone size, location in the ureter, kidney size and Hounsfield unit values, perinephric edema, and degree of hydronephrosis were assessed. Results Pale kidney sign was detected in 36%. Hydronephrosis was mild in 63% and severe in 21%; severe hydronephrosis was associated with larger stones. Mid-ureter and ureteropelvic junction stones were more likely to cause hydronephrosis. Perinephric edema (56%) was not correlated with stone size/location. Conclusion Only severe hydronephrosis was significantly associated with larger stone size.

Objective To describe the normal computed tomography (CT) appearance of the pelvis after uncomplicated Cesarean section (C-section). Patients and methods Pelvic CT examinations of 31 patients after uncomplicated C-section were reviewed. Results Higher postoperative day (POD) correlated well with decreases in the uterine long axis and endometrial width but did not correlate to scar width. Full thickness defect of the uterine wall was revealed in 48% of patients. Small volumes of intrauterine gas presented in half of patients at POD 1–26. Free pelvic fluid appeared in 74%. Pelvic collections were rare and small. Conclusion There is wide variability in pelvic CT appearance following uncomplicated C-section.

Purpose To describe the spectrum of radiological findings in 12 patients with H syndrome. Patients and Methods Various radiological examinations of 12 patients (M=9, F=3) with H syndrome were reviewed. Results Symmetrical thickening of the skin of the subcutaneous tissue at the lower half of the body (n=9, 75%), with retracted micropenis in males (n=5, 55%). Groin varices (n=5, 42%) and lymphadenopathy (n=5, 42%) were observed in severe cases. Severe symmetrical flexion deformities of the fingers (n=7, 58%) were relatively common. Conclusion Skin thickening with subcutaneous fat infiltration and deformities of the hands and feet are typical for H syndrome.
