Transurethral radiofrequency collagen denaturation, a nonsurgical treatment for stress urinary incontinence, reduces regional dynamic tissue compliance without causing tissue necrosis or gross tissue shrinkage, unlike transvaginal radiofrequency tissue ablation. This retrospective study evaluated long-term safety and efficacy in 21 patients from a 12-month, randomized controlled trial utilizing 3-day diaries and the Incontinence Quality of Life (I-QOL) survey. Significant increases in overall I-QOL scores 3 years or more post treatment was the primary end point. Secondary end points were reductions in frequency and severity of incontinence episodes. After 3 years, mean overall I-QOL score improvement was 12.7 (+/-26); 56% of patients achieved 50% or more reduction in frequency. No new adverse events occurred. These results indicate that radiofrequency collagen denaturation is safe and provides durable efficacy.
Recommendations for the work-up of asymptomatic microscopic hematuria (AMH) often derive from studies including both men and women. This study was undertaken to determine whether that work-up is appropriate for a female patient population. We studied 49 women referred to a urogynecologist for AMH. Patients underwent formal urinalysis, urine culture and cytology, cystoscopy, and either renal ultrasound or intravenous urography (IVU). Highly significant lesions diagnosed were one renal cell carcinoma and one acute tubular necrosis (ATN). Moderately significant lesions included one candidal urinary tract infection. Insignificant lesions included bladder inflammation in 46 patients and renal cysts in 5. Our findings confirm the importance of the work-up of AMH in women. Ultrasound was effective in diagnosing upper tract lesions, with less cost and morbidity than IVU. Larger studies are needed to determine who should be screened, whether the work-up should differ for younger women, possible treatments for benign findings, and appropriate follow-up.
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.
