Colour Doppler sonography of flaccid penis in evaluation of erectile dysfunction.

Background: Erectile dysfunction is a common and potentially treatable problem. Other than psychological, anatomical and metabolic factors, vasculogenic causes also play an important role in erectile dysfunction. Among the various diagnostic tools available for the diagnosis of vasculogenic causes, colour Doppler sonography is noninvasive, simple and promising.

Associated anomalies with anorectal malformation (ARM).

Objective: To find the prevalence of associated anomalies in children with anorectal malformation (ARM).

Methods: One hundred and forty patients (80 males and 60 females) with expand were studied to detect associated anomalies and to find their prevalence. High and low type of ARM was seen in 52.

Low-dose low-osmolar urography with iohexol.

Objectives: To study the diagnostic efficacy of low-dose iohexol (90 mg iodine/kg body weight) for intravenous urography.

Materials And Methods: Intravenous urography was performed using low-dose iohexol in 50 patients with various urinary complaints. Patients with elevated blood urea and serum creatinine levels were excluded.

An evaluation of myelography with non-ionic water soluble contrast medium-iohexol.

Iohexol myelography was performed in 25 cases of suspected spinal cord compression. Out of these, 24 cases gave optimally informative myelogram, while one case showed quasi-informative myelogram. Myelographic efficacy regarding the level of lesion was correct in all cases.

Comparative evaluation of commonly used catheters through histopathological changes induced in bladder urothelium.

There is growing concern about the toxic potential of chemicals coating various catheter materials, especially due to lack of international standards for toxicity testing. The present study evaluates the toxicity potential in terms of pathological changes induced by the catheters commonly used in practice, i.e.

Role of arthrography in non-traumatic painful wrist.

The arthrographic examination was carried out in 25 patients with non-traumatic painful wrist of more than 6 weeks duration. Plain x-rays were non-contributory in making any diagnosis in 20 cases. Arthrography was performed even when plain x-rays were normal and it revealed the soft tissue abnormalities and early phases of cartilage destruction not visible on routine roentgenograms.
