- Neurological status predicts response to alpha-blockers in men with voiding dysfunction and Parkinson's disease(2014) GOMES, Cristiano M.; SAMMOUR, Zein M.; BESSA JUNIOR, Jose de; BARBOSA, Egberto R.; LOPES, Roberto I.; SALLEM, Flavio S.; TRIGO-ROCHA, Flavio E.; BRUSCHINI, Homero; NITTI, Victor W.; SROUGI, MiguelOBJECTIVES: To evaluate predictors of the response to doxazosin, a selective alpha-adrenoceptor antagonist, when used for the treatment of lower urinary tract symptoms in men with Parkinson's disease. METHODS: In a prospective study, 33 consecutive men (mean age 59.2 +/- 7.0 years) with Parkinson's disease and lower urinary tract symptoms were evaluated. Neurological dysfunction was assessed with the Unified Parkinson's Disease Rating Scale. Urological assessment was performed at baseline and after 12 weeks of treatment with 4 mg/day of extended-release doxazosin, including symptom evaluation with the International Continence Society male short-form questionnaire, an assessment of the impact of lower urinary tract symptoms on quality of life and urodynamics. Clinical and urodynamic predictors of response were specifically evaluated. RESULTS: Compared with the score at baseline, the total International Continence Society male short-form score was reduced after doxazosin administration, from 17.4 +/- 7.5 to 11.1 +/- 6.9 (p<0.001). The impact of lower urinary tract symptoms on quality of life was also significantly reduced, from 1.8 +/- 1.1 to 1.0 +/- 1.0 (p<0.001) and the maximum urinary flow varied from 9.3 +/- 4.4 to 11.2 +/- 4.6 ml/s (p = 0.025). The severity of neurological impairment was the only predictor of the clinical response. Additionally, patients with a Unified Parkinson's Disease Rating Scale score lower than 70 had a significantly higher chance of clinical improvement with doxazosin treatment than those with higher Unified Parkinson's Disease Rating Scale scores did (RR = 3.10, 95% CI = [1.15 to 5.37], p = 0.011). CONCLUSIONS: Doxazosin resulted in the improvement of lower urinary tract symptoms and the maximum flow rate and was well tolerated in men with Parkinson's disease. The response to treatment is dependent on the severity of neurological disability.
- Renal function in children with congenital neurogenic bladder(2011) OLANDOSKI, Karen Previdi; KOCH, Vera; TRIGO-ROCHA, Flavio EduardoAIMS: Preservation of renal function in children with congenital neurogenic bladder is an important goal of treatment for the disease. This study analyzed the evolution of renal function in patients with congenital neurogenic bladder. METHODS: We reviewed the records of 58 pediatric patients with respect to the following attributes: gender, age, etiology of neurogenic bladder, reason for referral, medical/surgical management, episodes of treated urinary tract infections, urodynamics, DMSA scintigraphy, weight, height, blood pressure, glomerular filtration rate, microalbuminuria and metabolic acidosis. Statistical analysis was performed, adopting the 5% significance level. RESULTS: The mean age at presentation was 4.2 +/- 3.5 years. Myelomeningocele was the most frequent etiology (71.4%). Recurrent urinary tract infection was the reason for referral in 82.8% of the patients. Recurrent urinary tract infections were diagnosed in 84.5% of the patients initially; 83.7% of those patients experienced improvement during follow-up. The initial mean glomerular filtration rate was 146.7 +/- 70.1 mL/1.73 m(2)/min, and the final mean was 193.6 +/- 93.6 mL/1.73 m(2)/min, p = 0.0004. Microalbuminuria was diagnosed in 54.1% of the patients initially and in 69% in the final evaluation. Metabolic acidosis was present in 19% of the patients initially and in 32.8% in the final assessment. CONCLUSIONS: Patient referral to a pediatric nephrologist was late. A reduction in the number of urinary tract infections was observed with adequate treatment, but microalbuminuria and metabolic acidosis occurred frequently despite adequate management.
