Experimental study of the efficiency of lithotripsy with duplicate pulses.

BACKGROUND AND PURPOSE: Theoretical study had shown that compared with a single pulse, a duplicate pulse could improve the efficiency of lithotripsy. We conducted a series of studies to validate this idea. MATERIALS AND METHODS: The experimental study in vitro and in vivo used a lithotripsy machine with duplicate, single, and electromagnetic pulses. RESULTS: Use of a duplicate pulse improved the wastage of the model stones about 44.15% and the efficiency of lithotripsy about 44.76%. In pigs, the efficiency of lithotripsy was greater with a duplicate pulse than with single and electromagnetic pulses. CONCLUSION: Compared with single and electromagnetic pulses, duplicate pulses could improve the efficiency of lithotripsy by more than 40%.

[The challenge of male reproductive health].

[Prevention of prostatitis].

Prostatitis is a common disease in men without satisfactory therapeutics methods, and prevention of prostatitis becomes much more important. The main methods include treatment of general infection and secondardy infection of the prostate actively, diet and life-style modification, avoiding unnecessary medical examination, establishing good coping styles, giving publicity to the knowledge of prostate and prostate-related disease, and strengthening prevention in the post-prostatitis patients.

[Physicians' knowledge and attitude to erectile dysfunction].

OBJECTIVES: The physicians knowledge and attitude to erectile dysfunction (ED) is very important to the diagnosis and management of this disease. We investigated the physicians and practitioners knowledge of ED, attitude to ED, and if they actively find the underlying ED patients. METHODS: Three hundreds and one physicians and practitioners in Beijing completed a questionnaire. The subjects included urologists, cardiologists, endocrinologists, surgeons, orthopaedicians and community practitioners. RESULTS: The definition of ED was well known by most subjects (83.4%). Many agreed that ED was a common condition in the aging men (85.0%), and it was an important health problem (78.7%) and it was the local signs of certain systemic diseases (89.7%). The most common risk factors of ED enumerated by the physicians were diabetes (45.5%), hypertension (12.6%) and coronary artery diseases (12.0%). 45.5% physicians met the patients who initiated questions about ED. 32.6% physicians would discuss ED with the patients if the patients initiate questions about ED. 95.0% non-urological physicians would refer the ED patients to urologists or andrologists. 43.5% of all the physicians never asked their patients about erectile function, this proportions in the subgroups of urologists, non-urological physicians and community practitioners were 7.2%, 55.3% and 60.5% respectively (P < 0.01). The most common reasons for the physicians not to initiate the inquiries about ED was "the patients would not have ED if they didnt complain about it" (42.2%), "there was no ED patients in my specialty" (20.9%), "diagnosis and treatment of ED was not my business" (17.3%), "have no time" (15.6%), "feel embarrassed" (13.6%). CONCLUSIONS: Most physicians regarded ED as an important health problem and a common condition in aging men, but they didnt take an active attitude to ED in their clinical practice.
