To our knowledge, this is the first report of the laparoscopic resection of a retrocaval paraganglioma. For the resection of a paraganglioma, in this location, laparoscopy has the advantage of precise visualization, which helps to resect the tumor completely. Laparoscopic resection of a paraganglioma, despite the high level of compression of the IVC, is a feasible, reproducible technique with appropriate preoperative planning.
Introduction: We examined the tolerability of dosage methods of naftopidil in the treatment of male lower urinary tract symptoms associated with benign prostatic hyperplasia (BPH/male LUTS). Patients and Methods: A total of 80 patients with BPH/male LUTS who had an International Prostate Symptom Score (IPSS) ≧8 and IPSS quality of life (QoL) ≧2 were enrolled and randomly administered naftopidil for 8 weeks at either 75 mg once daily (OD) in the evening (group O; n = 41) or 25 mg thrice daily (TID) in the morning, afternoon and evening (group T; n = 39). Results: IPSS total score, IPSS-QoL and BPH impact index (BII) were significantly improved for both groups at 8 weeks after starting treatment compared to baseline. IPSS total score and daytime and 24-hour voiding frequencies were significantly improved at 8 weeks after starting treatment for group O in comparison to group T. Group O showed a significantly better degree of change in BII in comparison to group T. Conclusions: Naftopidil 75 mg OD in the evening was better tolerated than naftopidil 25 mg TID for the objective parameter and BII.
The diagnostic significance of transrectal prostatic ultrasonography for chronic prostatitis and varicocele was evaluated in 380 male infertility patients. Of 20 patients with pyospermia, thought to be mainly caused by chronic prostatitis, 10.0 percent showed heterogeneous echo pattern of the prostate, while 25.0 percent showed capsular irregularity. Since 285 patients with non-infected semen showed similar sonographic findings, it is concluded that prostatic ultrasonography has little value in the diagnosis of chronic prostatitis in infertile patients. Enlarged periprostatic echo-free zone, thought to coincide with the dilatation of the Santrini's plexus, was found in 42.9 and 42.7 percent of patients with chronic prostatitis and varicocele, respectively, in contrast to 34.0 percent of patients without either diseases. Twelve percent of patients with varicocele showed highly enlarged echo-free zone, which was significantly more frequent compared to 5.0 percent in normal patients. Moreover, follow up of 4 patients with varicocele pre- and post-operatively found 2 of them to show a great improvement in the enlargement of the zone. These results suggest that varicocele may cause the dilation of the Santrini's plexus through a venous anastomosis in some patients and transrectal ultrasonography may be a useful tool in detecting small varicoceles in such patients.
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.
