- Congenital genitourinary abnormalities in children with Williams-Beuren syndrome(2014) SAMMOUR, Zein M.; GOMES, Cristiano M.; BESSA JR., Jose de; PINHEIRO, Marcello S.; KIM, Chong A. E.; HISANO, Marcelo; BRUSCHINI, Homero; SROUGI, MiguelObjective: Williams-Beuren syndrome (WBS) is an autosomal dominant disorder caused by a gene deletion on chromosome 7q11.23. Patients with WBS usually show a group of features such as developmental delay, cardiovascular anomalies, mental retardation, and characteristic facial appearance. Abdominal wall defects, external genitalia anomalies, and structural abnormalities of the urinary tract have been scarcely evaluated and were the focus of our study. Materials and methods: We prospectively evaluated 41 boys and 38 girls with WBS, with a mean age of 8.8 +/- 4.1 (range 3-19 years). All patients were examined for the evaluation of inguinal and umbilical hernias and genital anomalies. All patients were offered a radiological evaluation, including urinary tract ultrasound, voiding cystourethrogram, and dimercaptosuccinic acid renal scintigraphy (DMSA scan). Results: Of the 41 boys, 30 (73.1%) had abnormalities on physical examination, including bilateral undescended testis in 13 (31.7%), retractile testis in four (9.7%), hypospadias in four (9.7%), and unilateral cryptorchidism in three (7.3%) patients. Of the 38 female subjects, 17 (44.7%) had at least one abnormality, including umbilical hernia in 11 (28.9%), unilateral inguinal hernia in four (10.5%), and bilateral inguinal hernia in three (7.8%) patients. Uroradiological abnormalities were found in 41 patients (51.9%). On sonography, six (7.6%) patients had unilateral hydronephrosis, three (3.8%) had a duplicated collecting system, and two (2.5%) had kidney stones. On DMSA, performed in 36 patients, four (11.1%) had unilateral renal scarring and two (5.5%) had bilateral renal scarring. Cystourethrography was obtained from 56 patients, of whom 27 (48.2%) had bladder diverticulum, 18 (32.1%) had bladder wall trabeculation, and three (5.3%) had vesicoureteral reflux. We found no association of urological abnormalities with cardiovascular defects. Conclusions: Patients with WBS have a high prevalence of abdominal wall, external genitalia, and urological abnormalities, emphasizing the importance of proper physical examination and radiological investigation in this population.
- Severe urinary tract damage secondary to primary bladder neck obstruction in women(2021) FREITAS, Pedro F. S.; COELHO, Augusto Q.; BRUSCHINI, Homero; ROVNER, Eric S.; GOMES, Cristiano M.Objective To present the clinical and radiological characteristics of women with severe structural deterioration of the bladder and upper urinary tract secondary to Primary Bladder Neck Obstruction (PBNO), and their outcomes after bladder neck incision (BNI). Methods Retrospective evaluation of adult women who underwent BNI for PBNO at one institution. Patients were assessed for symptoms, renal function, structural abnormalities of the urinary tract and video-urodynamics. PBNO diagnosis was confirmed with video-urodynamics in all patients. BNI was performed at the 4-5 and/or 7-8 o'clock positions. Postoperative symptoms, PVR, uroflowmetry and renal function were evaluated and compared to baseline. Results Median patient age was 56.5 years (range 40-80). All presented with urinary retention-four were on clean intermittent Catheterization (CIC) and two with a Foley catheter. All patients had bladder wall thickening and diverticula. Four women had elevated creatinine levels, bilateral hydronephrosis was present in five (83.3%). After BNI, all patients resumed spontaneous voiding without the need for CIC. Median Qmax significantly improved from 2.0 [1.0-4.0] mL/s to 15 [10-22.7] mL/s (p = 0.031). Median PVR decreased from 150 to 46 [22-76] mL (p = 0.031). There were no postoperative complications. Creatinine levels returned to normal in 3/4 (75%) patients. Conclusion PBNO in women may result in severe damage to the bladder and upper urinary tract. Despite severe structural abnormalities of the bladder, BNI was effective in reducing symptoms and improving structural and functional abnormalities of the lower and upper urinary tract.
- Longitudinal Improvement of Lower Urinary Tract Symptoms in Williams-Beuren Syndrome(2021) SAMMOUR, Zein M.; HISANO, Marcelo; JR, Jose de Bessa; BRUSCHINI, Homero; NAHAS, William C.; SROUGI, Miguel; GOMES, Cristiano M.Purpose: Williams-Beuren syndrome is a chromosomal disorder caused by a deletion at region 7q11.23. Lower urinary tract symptoms are highly prevalent and significantly affect quality of life. We assessed the long-term out-comes of lower urinary tract symptoms in children with Williams-Beuren syndrome. Materials and Methods: From February 2001 to July 2016, 90 patients with Williams-Beuren syndrome were evaluated in our hospital, of whom 31 (20 boys) had at least 5 years of followup. Baseline evaluation included a history of lower urinary tract symptoms, frequency-volume chart and the impact on quality of life measured on a scale of 0 (delighted) to 6 (terrible). Pharmacological therapy with oxybutynin or doxazosin was offered to symptomatic patients. We present the outcome of lower urinary tract symptoms after 5 and 10 years of followup. Results: At baseline 27 (87.1%) patients were symptomatic. Median duration of followup was 10 (range 6-13) years. Pharmacological therapy was started for 25 (92.6%) symptomatic patients at baseline, including oxybutynin for 19 (76.0%), doxazosin for 1 (4.0%) and a combination of the 2 agents for 5 (20.0%). Medical therapy was still in use by 61.2% after 5 years and 52.9% after 10 years (p=0.043). Median duration of pharmacological treatment was 7 (range 6-11) years. A significant improvement of lower urinary tract symptoms was observed over time, with 35.5% and 29.5% patients considered symptomatic after 5 years and 10 years, respectively (p < 0.001). Quality of life was also markedly improved over time (p < 0.001). Conclusions: This long-term study showed significant improvement of lower urinary tract symptoms in children and adolescents with Williams-Beuren syndrome over time. Long-term pharmacological treatment was needed in most patients.

- Impact of a 1-day urodynamic course on knowledge, perceptions, and attitudes of urology residents(2021) GOMES, Cristiano M.; BESSA, Jose de; NUNES, Ricardo V.; PREZOTTI, Jose; BRUSCHINI, Homero; GOMES, Marcio M.Aims No evidence-informed educational curriculum is available for designing urodynamics (UDS) courses. We evaluated the learning outcomes of a short-lasting urodynamic course for urology residents. Methods Urology residents of postgraduate years 4 and 5 (n = 13 and n = 1316, respectively) attended a 1-day urodynamic course. Learning objectives included patient preparation, indication and technique, terminology, trace interpretation, and impact on patient management. Instructional methods consisted of short lectures (3 h) and case-based discussions (7.5 h). Learners' reactions, modifications of perceptions and attitudes, and acquisition of knowledge and skills were assessed by three written tests with a single group, pretest, posttest 1, and posttest 2 design. Tests were conducted precourse, 1 week after, and 4 months after the course. Results All participants felt more confident in several urodynamic competencies after the course, including patient preparation, urodynamic indication and technique, terminology, trace interpretation, and impact for patient management. These perceptions remained unchanged after 4 months. Most became stricter in the indication of UDS, including 20 (87.0%) at posttest 1 and 8 (66.7%) at posttest 2. The mean number of correct answers in the knowledge evaluation was 52.2% versus 61.4% versus 56.7%, respectively at pretest, posttest 1, and posttest 2; p = 0.535). All participants rated the course as very useful or useful in both posttest evaluations. Conclusions Our study demonstrates that a 1-day urodynamic course can promote lasting improvements in self-reported perceptions, attitudes, and urodynamic-related competencies of urology residents. Further studies using evidence-informed educational principles are needed to determine the effect of specific educational interventions on urodynamic competencies in different contexts.
- 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.
- FEMALE SEXUAL DYSFUNCTION AFTER SPINAL CORD INJURY(2013) GOMES, Cristiano M.; BELLUCCI, Carlos H. S.; BESSA JR., Jose; CASTRO FILHO, Jose E.; PINHEIRO, Marcello S.; BRUSCHINI, Homero; SROUGI, Miguel
- Erectile Function Predicts Sexual Satisfaction in Men With Spinal Cord Injury(2017) GOMES, Cristiano M.; MIRANDA, Eduardo P.; BESSA JR., Jose de; BELLUCCI, Carlos Henrique Suzuki; BATTISTELLA, Linamara Rizzo; ABDO, Carmita Helena Najjar; BRUSCHINI, Homero; SROUGI, Miguel; MULHALL, John P.Introduction: Spinal cord injury (SCI) is usually a sudden traumatic event and has a negative effect on sexual function. Aim: To evaluate the characteristics of sexual activity in men with SCI and identify predictors of being sexually active and having a satisfactory sex life. Methods: We assessed sexual activity profiles of men with SCI from a Brazilian tertiary rehabilitation center from February to August 2012. All patients older than 18 years with SCI for longer than 1 year were invited to participate. We analyzed age, time since SCI, patient age at SCI, employment status, partner status, completeness of lesion, functional independence, urinary continence, and Sexual Health Inventory for Men (SHIM) score. Main Outcome Measures: The SHIM was used to assess erectile function (EF). Satisfaction with sex life was analyzed as a dichotomous variable. Predictors of an active and satisfactory sex life were identified using univariable and multivariable analyses. Results: We evaluated 295 men with mean age of 40.7 +/- 14.5 years. Most patients had a complete SCI (65.1%) and 159 (53.9%) were incontinent. The median SHIM score was 5 (interquartile range = 0-16) and only 71 men (24.1%) had a SHIM score of at least 17. Of these men, 159 (53.9%) were sexually active. Only 63 men (39.6%) were satisfied with their sex life after SCI. In univariable analysis, all variables were associated with an active sex life. Those with a SHIM score of at least 17 had a greater likelihood of being sexually active (odds ratio = 116, 95% confidence interval = 14-432). EF was the only parameter associated with a satisfactory sex life (odds ratio = 1.3, 95% confidence interval = 1.2-1.4). Conclusions: Most men with SCI were sexually inactive and/or dissatisfied with their sex life. Age, duration of SCI, completeness of SCI, continence, having a partner, and good EF were identified as predictors of an active sex life. However, only EF was a predictor of a satisfactory sex life.
- Increased detrusor collagen is associated with detrusor overactivity and decreased bladder compliance in men with benign prostatic obstruction(2017) BELLUCCI, Carlos H. S.; RIBEIRO, Wesley de O.; HEMERLY, Thiago S.; BESSA JR., Jose de; ANTUNES, Alberto A.; LEITE, Katia R. M.; BRUSCHINI, Homero; SROUGI, Miguel; GOMES, Cristiano M.Background: This study aimed to investigate the relationship between detrusor collagen content and urodynamic parameters in men with benign prostatic obstruction. Material and methods: Nineteen consecutive patients undergoing open prostatectomy for bladder outlet obstruction (BOO) due to be nign prostatic hyperplasia (BPH) were evaluated. Urodynamic tests were performed in all patients. BOO and detrusor contractility were assessed with the BOO index (BOOI) and the bladder contractility index (BCI), respectively. A bladder fragment was obtained during prostatectomy. Eight cadaveric organ donors composed the control group. Bladder sections were stained with picrosirius red and hematoxylin-eosin. The collagen to smooth muscle ratio (C/M) in the detrusor was measured and its relationship with urodynamic parameters was investigated. Results: Seven (36.8%) patients were operated on due to lower urinary tract symptoms and 12 (63.2%) had urinary retention. The mean prostate volume was 128.6 cm(3) +/- 32.3 cm(3), the mean BOOI was 76.4 +/- 33.0, and the mean BCI was 116.1 +/- 33.7. The mean C/M in BPH patients and controls were 0.43 +/- 0.13 and 0.33 +/- 0.09, respectively (P = 0.042). A negative correlation was shown between C/M and bladder compliance (r = -0.488, P = 0.043). The C/M was increased in BPH patients with detrusor overactivity (DO) compared to those without DO (0.490 +/- 0.110 and 0.360 +/- 0.130, respectively; P = 0.030) and also in patients with urinary retention (P = 0.002). No correlation was shown between C/M and maximum cystometric capacity, BOOI, or BCI. Conclusion: Men with BOO/BPH have increased detrusor collagen content which is associated with decreased bladder compliance, detrusor overactivity, and urinary retention.
