RESUMEN
OBJECTIVE: To analyze intravenous urography (IVU) findings in a tertiary reference center. MATERIALS AND METHODS: A retrospective, observational study was conducted in a tertiary reference center. The radiology reports of 1,470 patients subjected to IVU in the period from January 2008 to December 2012 were retrieved from the tertiary reference center databases. Patients' demographic characteristics, type of care (inpatient or outpatient), and IVU radiologic findings were reviewed and analyzed. RESULTS: Of 1470 patients, approximately two-thirds were males. The mean age of the patients was 39.12±14.80 years (range: 2-95). Most of them were inpatients (92.9%; 1365/1470). The IVU findings were abnormal in 68.8% (1012/1470) of patients. Urinary tract calculi were the most frequent type of calculi observed among patients (36.8%; 541/1470), and the kidney was the most frequently affected organ by calculi (66.5%; 541/814). Hydronephrosis was the second most frequent finding, being observed in 29.7% (436/1470) of patients. CONCLUSION: The presence urinary tract calculi was the most frequent IVU finding, revealing that urolithiasis could be the main indication for IVU.
RESUMEN
OBJECTIVE: Khat, a type of plant that grows in Yemen and some African countries like Somalia, Ethiopia and Kenya, is considered to be addictive and contains some stimulating substances that may affect different body organs. This study was conducted to identify the causes of erectile dysfunction (ED) and to investigate the effect of chewing Khat on this disease in Yemenis. MATERIALS AND METHODS: A total of 236 patients who were treated at University of Science and Technology Hospital and complained of ED were examined with penile Doppler ultrasonography (US). Biodata and health data were collected from the patients' records and via mobile interviews. RESULTS: The causes of ED were psychological causes (72%), venous leakage (19%) and arterial disease (9%). Psychological ED was most common in 15-29-year-olds, while pathological ED increased with increasing age (p=0.041). Heart diseases and diabetes showed a significant association with pathological ED (p<0.05). Although 81% of the ED patients in this study chewed Khat, there was no significant association between chewing Khat and either pathological or psychological ED (p>0.05). CONCLUSION: Psychological problems are the main causes of ED among Yemenis especially in the younger age group. It is too early to exclude Khat as a factor contributing to this health problem, and this topic warrants further case-control studies with a larger sample size.
