The lower calix is responsible for a significant number of kidneys with residual stone fragments after extracorporeal shock wave lithotripsy (ESWL*). To compare the effectiveness of controlled inversion therapy as an adjunctive method to the elimination of calculous fragments, 42 patients who had undergone treatment for lower caliceal stones with a Siemens(More)
Between October 1989 and June 1991, 1,250 patients with urinary calculi were treated at our institution using the Siemens Lithostar. A total of 17 patients (1.37%) with radiolucent or slightly opaque calculi underwent lithotripsy with the Lithostar Plus, which has an overhead electromagnetic generator module and a localization system composed of a real-time(More)
Two therapeutic methods, endourology and extracorporeal shock wave lithotripsy (ESWL), can be used in the treatment of ureteral calculi. In a retrospective analysis during a 2-year period 236 patients treated with endourological procedures and 71 who underwent ESWL with a Siemens Lithostar were analyzed as to the success rate, effectiveness quotient,(More)
The possibility of retrograde ejaculation or impotence after transurethral resection of the prostate has led to searches for other treatments for benign hyperplasia (BPH). Transurethral microwave thermotherapy (TUMT) was administered to 100 men with a mean age of 61 years and moderate to severe BPH in one 60-minute outpatient session without anesthesia. A(More)
For assessing plasma and tissue concentrations of norfloxacin after oral administration, twelve patients with benign prostatic hypertrophy (BPH) were given two doses of 400 mg norfloxacin approximately 12 hours apart prior to transurethral resection of the prostate (TURP). Prostatic tissue samples and blood samples were collected and assayed for norfloxacin(More)
Percutaneous nephrolithotomy and extracorporeal shock wave lithotripsy (ESWL*) can be used in the treatment of lower pole caliceal calculi. In a retrospective analysis these 2 therapies were compared for treatment of solitary lower pole caliceal calculi to evaluate morbidity. During a 2-year period 23 patients treated with percutaneous nephrolithotomy and(More)
PURPOSE Transurethral resection of the prostate (TURP) is still the gold standard method to treat benign prostatic hyperplasia (BPH). Transurethral vaporization of the prostate (TUVP) is compared with the transurethral resection of benign prostatic hyperplasia. PATIENTS AND METHODS Over a 10-month period, 78 patients presenting with moderate and severe(More)
OBJECTIVE To compare the effectiveness, safety and tolerability of sildenafil and apomorphine in Brazilian patients with erectile dysfunction (ED) of various causes. PATIENTS AND METHODS In all, 108 patients (mean age 55 years, sd 11) and documented ED for > or =6 months were included in 12 centres in Brazil. The patients were initially followed for 2(More)
