PURPOSE The efficacy of shock wave lithotripsy and percutaneous stone removal for the treatment of symptomatic lower pole renal calculi was determined. MATERIALS AND METHODS A prospective randomized, multicenter clinical trial was performed comparing shock wave lithotripsy and percutaneous stone removal for symptomatic lower pole only renal calculi 30 mm.(More)
The introduction of extracorporeal shock wave lithotripsy (ESWL) has provided an avenue for dealing with many urinary stones noninvasively. The margin of safety for the kidney during shock wave administration is largely undefined. A pilot study was performed where six kidneys in five female mongrel dogs were shocked. Group A kidneys were given 1,776, 4,500,(More)
The ureteroscopic approach to ureteral strictures has diminished morbidity because of smaller-caliber equipment, improved optics, Ho:YAG laser, and a better understanding of the risk factors for ureteral strictures. Direct visualization by means of retrograde ureteroscopy provides a safe and effective approach to treat ureteral strictures without the need(More)
One hundred and four (70%) of the first 148 patients who underwent extracorporeal shock-wave lithotripsy (ESWL) at the University of Florida were evaluated for persistent or recurrent renal stone disease. Radiographs obtained 3-21 months after treatment showed that 53 (50%) of 106 treated kidneys were free of stones. In 48 of the 53 kidneys that contained(More)
Of 148 patients who had extracorporeal shock-wave lithotripsy (ESWL) for renal lithiasis in 1984, 21 (14%) returned after 17-21 months for renal function tests (21 patients) and blood pressure determination (20 patients). Quantitative radionuclide renography showed a statistically significant (p = .048) decrease in the percentage of effective renal plasma(More)
The immediate posttreatment findings are described for 100 patients who underwent extracorporeal shock wave lithotripsy (ESWL) for renal stone disease. Excretory urography was performed both before and 24-72 hours after ESWL. In 21 patients, stones were completely disintegrated, and stone fragments were passed rapidly. Stones were fragmented but not passed(More)
OBJECTIVES Significant obesity is considered to be a relative contraindication to laparoscopic surgery. This study reviews the complications encountered in massively obese patients undergoing urologic laparoscopic surgery. METHODS Body mass index (BMI) was used as an objective index to indicate massive obesity. Eleven institutions compiled retrospective(More)
We investigated the value of real-time sonography for determination of pelvicaliceal dilatation 24-48 h after extracorporeal shock wave lithotripsy (ESWL) in 369 patients (419 treated kidneys). A varying degree of hydronephrosis was present in 121/419 (29%) kidneys. Fragmented stones post-ESWL were demonstrable in 346/419 kidneys (82%), but were missed by(More)
We assessed the physical activity level, smoking habits, alcohol consumption, ponderosity, and plasma lipid profiles of 688 middle-aged male reserve officers. When adjusting for Body Mass Index (BMI), individuals who reported physical activity of three or more times per week had significantly higher levels of high density lipoprotein cholesterol (HDL-C),(More)
