Objectives: To prospectively evaluate the efficacy of single dose antibiotic prophylaxis in 12-core transrectal ultrasonography (TRUS) guided prostate biopsy. Methods: A total of 400 patients who underwent prostate biopsy with TRUS guidance were included. The patients were prospectively randomized in three groups regarding antibiotic prophylaxis. The first group (139 patients) received a single gram of intramuscular ceftriaxone, while the second group (131 patients) had a 3-day course of oral ciprofloxacin. The third group (130 patients) had single oral 500 mg of ciprofloxacin. All patients had urine cultures prior to biopsy and on the second day after biopsy. Results: The study groups were compared in terms of the results of urine cultures and clinical parameters. Overall, only seven patients (1.8% of the cases) had positive urine cultures with no difference between these three groups. Additionally, no significant difference was observed regarding morbidity rates in all groups. Only eight patients (2%) developed major complications requiring hospitalization. There was no increase in the rate of infectious complications when the biopsy core numbers were increased up to 12. Conclusions: The current study suggests that a single oral dose of antimicrobial prophylaxis is reasonable in TRUS prostate biopsy even in the case of 12-core sampling.
Air pollution is contemporarily considered to be a significant cause in impairing semen parameters. The aim of this study was to investigate possible effects of traffic pollutants, mainly the diesel exposure, on semen analysis. A total of 38 men working as toll collectors at motorways formed the study group. Simultaneously, 35 men working as office personnel constituted the control group. Factors including varicocele, chronic diseases that can affect sperm production were the exclusion criteria. No difference regarding smoking was present between the groups. Usual semen analysis according to WHO guidelines was performed. The results of semen analysis revealed decreased motility and low sperm counts in eight and seven men from the study group respectively. Besides, a man from the same group had combined abnormality of decreased motility and low sperm count. However, two men from the control group had slight motility defect and one had low sperm count. The differences regarding the abnormal sperm count and motility were significant between the groups (P = 0.002 and P = 0.003, respectively). Similarly, the ratio of sperm cells with normal morphology was significantly lower in the study group than that in the control group (P = 0.001). This observation proposes that air pollution particularly diesel exposure may have detrimental effects on sperm parameters.
Most bladder tumors are derived from the urothelium. Benign mesenchymal tumors are rare. Leiomyomas account for less than 0.43% of all bladder tumors. Genitourinary leiomyomata may arise in any anatomic structure containing smooth muscle. They have been reported to involve single or multiple organs. Since they may also mimic malignant lesions, they should always be considered in the differential diagnosis of any pelvic mass, with a possibility of being asymptomatic and discovered incidentally by radiographic imaging. We, herein, report a case illustrating clinical and pathological features in particular immunohistochemistry, and discuss its etiology and differential diagnosis.
The current study suggested that adding intraprostatic local anesthesia provides a significantly efficient strategy during transrectal ultrasound prostate biopsy, even in cases of 12-core sampling. Subsequent trials are needed to establish a standard analgesia policy for prostate biopsy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
