INTRODUCTION Extracorporeal shockwave lithotripsy (ESWL) is the treatment modality of choice of many urologists for proximal ureteric calculi. In this study, we compared the efficacy and safety of ESWL versus ureteroscopy with holmium laser lithotripsy for the treatment of this group of stones. MATERIALS AND METHODS Between May 1999 and October 2000, 50(More)
OBJECTIVE To study the epidemiology of overactive bladder (OAB) and the influence of demographic factors on its incidence in Asian men. SUBJECTS AND METHODS A survey based on a self-administered questionnaire (locally translated in participating countries) was conducted between March 1998 and May 1998 to quantify the prevalence of OAB in a random sample(More)
OBJECTIVE To determine the safety and efficacy of laparoscopic varicocelectomy in the treatment of symptomatic varicocele. PATIENTS AND METHODS Indications for surgery were subfertility in 98 patients and pain in nine. All varicoceles were confirmed on Doppler ultrasound. Seventy-two per cent of the patients had left-sided varicoceles and bilateral(More)
OBJECTIVE To assess the advantages of patient-controlled analgesia (PCA)-in patients undergoing extracorporeal shockwave lithotripsy (ESWL) for urinary stones. PATIENTS AND METHODS Between December 1995 and May 1996, a prospective study was carried out on 100 patients who underwent ESWL for urinary stones. The patients were assigned to two equal groups,(More)
A study was made of 30 cases of acute urethral trauma treated over a 7-year period. There were 10 anterior and 20 posterior urethral injuries, the majority of these being partial ruptures. Posterior urethral injuries were caused by road traffic accidents in 75% of cases while 80% of the anterior urethral injuries were of the "straddle" type. There was only(More)
INTRODUCTION The incidence of erectile dysfunction (ED) has been shown to increase significantly in Singaporean male population. Thus, this prospective study (no controls) assessed the clinical efficacy and safety of a medicated urethral system for erection (MUSE) in Singaporean male patients with a known history of ED. SUBJECTS AND METHOD Eighty-six men(More)
Specific lots of Anthrax Vaccine Adsorbed, administered to members of the US Armed Forces, have been described on various Internet sites and in news articles as a source of squalene, a chemical purported by these media to be associated with the Gulf War Syndrome. We have developed and validated a method using high-performance liquid chromatography with(More)
INTRODUCTION To evaluate the efficacy and safety of the holmium:YAG laser in retrograde ureteroscopic laser lithotripsy of ureteric calculi. METHODS Three hundred and twenty-five patients (256 males and 69 females) with mean age of 45 years underwent 328 retrograde ureteroscopic laser lithotripsy as the primary therapy for ureteric calculi using semirigid(More)
We report our experience with pulsed dye laser lithotripsy in the treatment of 100 ureteric stones in 95 patients over a 14-month period from July 1989 to September 1990. The overall rate of successful stone fragmentation was 97%. There was a low incidence of minor complications--mild haematuria, ureteric colic and urinary tract infection; ureteric(More)
OBJECTIVE BTA stat is a rapid, urine-based test for bladder cancer that detects human complement factor H related protein (HCFHrp) by monoclonal assay. This aim of this study was to assess the efficacy of BTA stat as a diagnostic tool for bladder cancer in symptomatic patients suspected of bladder cancer and in the surveillance of patients with a history of(More)
