RESUMEN

OBJECTIVE: With the development of analytical methods, mathematical models based on humoral biomarkers have become more widely used in the medical field. This study aims to investigate the risk factors associated with the occurrence of bladder spasm after transurethral resection of the prostate (TURP) in patients with prostate enlargement, and then construct a nomogram model. MATERIALS AND METHODS: Two hundred and forty-two patients with prostate enlargement who underwent TURP were included. Patients were divided into Spasm group (n=65) and non-spasm group (n=177) according to whether they had bladder spasm after surgery. Serum prostacyclin (PGI2) and 5-hydroxytryptamine (5-HT) levels were measured by enzyme-linked immunoassay. Univariate and multivariate logistic regression were used to analyze the risk factors. RESULTS: Postoperative serum PGI2 and 5-HT levels were higher in patients in the Spasm group compared with the Non-spasm group (P<0.05). Preoperative anxiety, drainage tube obstruction, and elevated postoperative levels of PGI2 and 5-HT were independent risk factors for bladder spasm after TURP (P<0.05). The C-index of the model was 0.978 (0.959-0.997), with a χ2 = 4.438 (p = 0.816) for Hosmer-Lemeshow goodness-of-fit test. The ROC curve to assess the discrimination of the nomogram model showed an AUC of 0.978 (0.959-0.997). CONCLUSION: Preoperative anxiety, drainage tube obstruction, and elevated postoperative serum PGI2 and 5-HT levels are independent risk factors for bladder spasm after TURP. The nomogram model based on the aforementioned independent risk factors had good discrimination and predictive abilities, which may provide a high guidance value for predicting the occurrence of bladder spasm in clinical practice.

RESUMEN

PURPOSE: To create a nomogram to predict the absence of clinically significant prostate cancer (CSPCa) in males with non-suspicion multiparametric magnetic resonance imaging (mpMRI) undergoing prostate biopsy (PBx). MATERIALS AND METHODS: We identified consecutive patients who underwent 3T mpMRI followed by PBx for suspicion of PCa or surveillance follow-up. All patients had Prostate Imaging Reporting and Data System score 1-2 (negative mpMRI). CSPCa was defined as Grade Group ≥2. Multivariate logistic regression analysis was performed via backward elimination. Discrimination was evaluated with area under the receiver operating characteristic (AUROC). Internal validation with 1,000x bootstrapping for estimating the optimism corrected AUROC. RESULTS: Total 327 patients met inclusion criteria. The median (IQR) age and PSA density (PSAD) were 64 years (58-70) and 0.10 ng/mL2 (0.07-0.15), respectively. Biopsy history was as follows: 117 (36%) males were PBx-naive, 130 (40%) had previous negative PBx and 80 (24%) had previous positive PBx. The majority were White (65%); 6% of males self-reported Black. Overall, 44 (13%) patients were diagnosed with CSPCa on PBx. Black race, history of previous negative PBx and PSAD ≥0.15ng/mL2 were independent predictors for CSPCa on PBx and were included in the nomogram. The AUROC of the nomogram was 0.78 and the optimism corrected AUROC was 0.75. CONCLUSIONS: Our nomogram facilitates evaluating individual probability of CSPCa on PBx in males with PIRADS 1-2 mpMRI and may be used to identify those in whom PBx may be safely avoided. Black males have increased risk of CSPCa on PBx, even in the setting of PIRADS 1-2 mpMRI.

RESUMEN

PURPOSE: Parasacral Transcutaneous Electrical Stimulation (TENS) is one of the treatments for children with Bladder and Bowel Dysfunction (BBD). Some studies showed that children with increased Rectal Diameter (RD) have more Functional Constipation (FC). However, RD prediction in maintenance of BBD after treatment was never evaluated. Our aim is to evaluate the association between RD and response to treatment in children and adolescents with BBD. MATERIALS AND METHODS: This study evaluated patients from 5-17 years old with BBD. Dysfunctional Voiding Scoring System (DVSS), Rome IV criteria, and the Constipation Score were used. RD was measured using abdominal ultrasound before treatment according to the technique established by Klijn et al. and was considered enlarged when >3cm. No laxatives were used during treatment. Descriptive analysis and binary regression were performed and the area under the ROC curve was calculated. RESULTS: Forty children were included (mean age 8.4±2.8 years, 52.5% male). Before treatment, RD was enlarged in 15 children (37.5%) (mean diameter 3.84±0.6cm), with FC persisting post-treatment in 11/15(73.3%). Those patients also required more laxatives following treatment and had more severe FC. Binary regression showed pretreatment RD to be an independent predictor of the persistence of FC post-treatment (OR=9.56; 95%CI:2.05-44.60). In ROC curve analysis, the sensitivity was 100% (95%CI: 0.49-1.0) and specificity 77.14% (95%CI:0.60-0.90) for rectal diameter >3 cm. The likelihood ratio was 4.38 (95%CI:2.40-8.0) for the persistence of BBD following treatment. CONCLUSION: RD appears to be relevant in the evaluation of children with BBD, not only as a diagnostic tool but also as a predictor of treatment outcome.

RESUMEN

OBJECTIVE: To determine the value of microbubble contrast cystosonography in the diagnosis of bladder rupture in animals. DESIGN: Prospective, method comparison study from November 2019 to October 2020. SETTING: University teaching hospital. ANIMALS: Thirty-four ethically sourced cadavers of dogs, rats, and rabbits. INTERVENTIONS: In a prospective and blinded study, the cadavers were divided into 2 randomized groups: with bladder rupture (CR), and without bladder rupture (SR). Urinary catheterization was performed in all cadavers. Through the urethral catheter, bladders in CR group were ruptured using a rigid stainless steel guide wire. Microbubble contrast was infused into the bladder through the urethral catheter, while a single, blinded observer sonographically assessed the bladder. The time to diagnosis and the number of attempts needed for diagnosis were recorded. MEASUREMENTS AND MAIN RESULTS: The study included cadavers of 16 female Wistar rats, 6 female dogs, 11 male dogs, and 1 male rabbit. Time to diagnosis in dogs (2.25 ± 0.91 min) was statistically higher when compared to rats (1.15 ± 0.75 min; P = 0.03). Of the 34 cases, incorrect diagnosis of bladder rupture was made in only 2 dogs (6%), indicating a diagnostic sensitivity of 88.88%, specificity of 100%, and an accuracy of 94%. The positive predictive value was 1 and the negative predictive value was 0.9. CONCLUSIONS: Our study showed that the described method is accurate, sensitive, and specific for the detection of bladder rupture in animal cadavers of different species, size, and sex.

RESUMEN

A 2-year-old English bulldog presented history of recurrent lower urinary tract disease, refractory to treatment. The Complete Blood Count revealed lymphopenia, hyperproteinemia, and hyperglobulinemia, while urinalysis indicated leukocyturia and bacteriuria. On the abdominal ultrasound, the bladder had a focal wall thickening in its cranial portion, as well as irregular echogenicity and internal margins. A bladder surgical biopsy was performed, indicating the presence of follicular cystitis. Clinical signs disappeared after treatment with a combination of amoxicillin and clavulanic acid, NSAIDs, supplementation with cranberry extract associated with cat's claw (Uncaria tomentosa). Clinical follow-up 12 months after surgery showed remission at all clinical signs. Follicular cystitis in dogs was reported only once worldwide, this case report is the first in Brazil; thus, it may be considered in the differential diagnosis for patients with refractory and recurrent lower urinary tract disease.


Um Bulldog Inglês de 2 anos apresentou história clínica de doença recorrente do trato urinário inferior, refratária ao tratamento. O hemograma revelou uma discreta linfopenia, hiperproteinemia e hiperglobulinemia. Já a urinálise apontou leucocitúria e bacteriúria. Na ultrassonografia, a bexiga apresentava espessamento focal da parede da bexiga em porção cranial, ecogênica e margens internas irregulares. A biópsia cirúrgica da bexiga foi compatível com cistite folicular. Os sinais clínicos desapareceram após o tratamento com uma combinação de amoxicilina - ácido clavulânico, AINEs, suplementação alimentar de extrato de cranberry associado a unha de gato (fitoterápico da planta Uncaria tomentosa). O acompanhamento, 12 meses após a cirurgia, confirmou que o cão estava livre de sinais clínicos. A cistite folicular foi relatada apenas em 1 cão no mundo, sendo esse considerado o primeiro relato no Brasil. Essa enfermidade deve ser considerada um diferencial para pacientes com doença refratária do trato urinário inferior de longa data.

RESUMEN

PURPOSE: Bladder endometriosis (BE) accounts for 84% of cases of urinary tract involvement. The use of cystoscopy for preoperative evaluation is limited. The aim of this study was to evaluate the accuracy of preoperative dynamic cystoscopy (DC) in patients undergoing surgery for deep endometriosis and to describe the main findings and their impact on surgical planning. MATERIALS AND METHODS: This cross-sectional observational study was conducted from January 2011 to March 2022. DC findings were divided into two groups according to the depth of involvement. To estimate sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV), laparoscopic findings of bladder involvement and histopathological report were used as the gold standard. RESULTS: We included 157 patients in this study. 41 had abnormalities in DC. Of these, 39 had abnormalities that were confirmed intraoperatively. The sensitivity and specificity of the test were 58.21% and 97.78%, respectively. PPV was 95.12%, and NPV was 75.86%. The presence of any lesions in the DC had a diagnostic odds ratio (OR) of 61.28 for BE. Patients with BE type 2 had a higher rate of partial cystectomy than those with BE type 1 lesions (OR 9.72 CI 95% 1.9-49.1) Conclusion: DC appears to be a highly specific test with lower sensitivity. DC abnormalities are associated with a higher ratio of bladder surgery for the treatment of deep endometriosis, and BE type 2 seems to be associated with a greater ratio (9.72) of partial cystectomy.

RESUMEN

Detrusor hypocontractility (DH) is a disease without a gold standard treatment in traditional medicine. Therefore, there is a need to develop innovative therapies. The present report presents the case of a patient with DH who was transplanted with 2 x 106 adipose tissue-derived mesenchymal stem cells twice and achieved significant improvements in their quality of life. The results showed that cell therapy reduced the voiding residue from 1,800 mL to 800 mL, the maximum cystometric capacity from 800 to 550 mL, and bladder compliance from 77 to 36.6 mL/cmH2O. Cell therapy also increased the maximum flow from 3 to 11 mL/s, the detrusor pressure from 08 to 35 cmH2O, the urine volume from 267 to 524 mL and the bladder contractility index (BCI) value from 23 to 90. The International Continence on Incontinence Questionnaire - Short Form score decreased from 17 to 8. Given the above, it is inferred that the transplantation of adipose tissue-derived mesenchymal stem cells is an innovative and efficient therapeutic strategy for DH treatment and improves the quality of life of patients affected by this disease.


A Hipocontratilidade Detrusora (HD) é uma doença sem um tratamento padrão-ouro na medicina tradicional. Logo, há a necessidade de desenvolvimento de terapias inovadoras. O presente relato apresenta um caso de paciente com HD transplantado duas vezes com 2 x 106 células-tronco mesenquimais derivadas do tecido adiposo que obteve melhoras significativas em sua qualidade de vida. Os resultados demonstraram que a terapia celular reduziu o resíduo miccional de 1.800mL para 800mL; a Capacidade Cistométrica Máxima de 800 para 550mL; a complacência de 77 para 36,6mL/cmH2O. A terapia celular também aumentou o fluxo máximo de 3 para 11mL/s; a pressão detrusora de 08 para 35cmH2O; o volume urinado de 267 para 524mL e o índice de contratilidade vesical (BCI) de 23 para 90. O score do International Continence on Incontinence Questionare - Short Form passou de 17 para 8. Diante do exposto, infere-se que o transplante de células-tronco mesenquimais derivadas do tecido adiposo é uma estratégia terapêutica inovadora e eficiente para o tratamento da HD e para melhoria da qualidade de vida de pacientes acometidos por essa doença.

RESUMEN

BACKGROUND: While bladder dysfunction is observed in the majority of patients with human T cell lymphotropic virus type 1 (HTLV-1)-associated myelopathy (HAM), it is also observed in patients who do not fulfill all diagnostic criteria for HAM. These patients are classified as having possible or probable HAM/TSP. However, it remains unclear whether the severity and progression of bladder dysfunction occurs similarly between these two groups. OBJECTIVE: Compare the severity and evolution of bladder dysfunction in HTLV-1-infected patients with possible and definite HAM/TSP. METHODS: The present prospective cohort study followed 90 HTLV-1 patients with possible HAM/TSP and 84 with definite HAM/TSP between April 2011 and February 2019. Bladder dysfunction was evaluated by bladder diary, overactive bladder symptoms scores (OABSS) and urodynamic studies. Bladder dysfunction progression was defined as the need for clean self-intermittent catheterization (CIC). RESULTS: At baseline, nocturia, urgency and OABSS scores were worse in definite compared to possible HAM/TSP patients. The main urodynamic finding was detrusor overactivity, present in 77.8% of the patients with definite HAM/TSP versus 58.7% of those with possible HAM/TSP (P = 0.05). Upon study conclusion, the cumulative frequency of patients requiring CIC increased in both groups, from 2 to 6 in possible HAM/TSP and from 28 to 44 in definite HAM/TSP patients. The estimated time to need for CIC was 6.7 years (95%CI 6.5-7.0) in the possible HAM/TSP group compared to 5.5 years (95%CI 4.8-6.1) in the definite HAM/TSP group. CONCLUSIONS: Although both groups showed similarities in bladder dysfunction and tended to progress to requiring CIC over time, patients with possible HAM/TSP presented less severe manifestations at baseline and progressed more slowly than those with definite HAM/TSP.

RESUMEN

ABSTRACT Purpose: Posterior urethral valves (PUVs) are the most common cause of congenital bladder obstruction in boys. Our aim was to assess the impact of early diagnosis and fulguration of PUVs on bladder function and compare their functional and urodynamic outcome with children who underwent delayed intervention. Materials and Methods: We retrospectively evaluated 153 patients who underwent primary valve ablation from two tertiary hospitals between 2001 and 2018. Patients have been divided into 2 groups, group 1 included 69 patients who were detected antenatally and underwent early fulguration of PUVs while group 2 included 84 children presented postnatally and underwent delayed valve ablation. The recorded data throughout follow-up in renal function tests, urodynamics and changes in the upper urinary tracts were evaluated and compared. Results: Median age at time of valve ablation was 10 days in group 1 and 7 months in group 2. The median follow-up period was 6.5 and 7 years in group 1 and 2, respectively. Chronic kidney disease (CKD) developed in 15 (22%) boys in group 1 while in group 2 it was observed in 31 (37%), p=0.04. While Q-max, mean bladder capacity and post-void residual (PVR) volumes were comparable in both groups, percent PVR was significantly higher in group 2 (3.27 vs. 1.44, p=0.002). Detrusor overactivity was slightly different in both groups (p = 0.07). Conclusions: Compared to delayed intervention, primary ablation of PUVs during the early neonatal life possibly provides the optimum chance to have optimum renal function without impact on bladder function.

RESUMEN

Methylglyoxal (MGO) is a reactive carbonyl species found at high levels in blood of diabetic patients. The anti-hyperglycemic drug metformin can scavenger MGO and reduce the formation of advanced glycation end products (AGEs). Here, we aimed to investigate if MGO-induced bladder dysfunction can be reversed by metformin. Male C57/BL6 mice received 0.5% MGO in drinking water for 12 weeks, and metformin (300 mg/kg, daily gavage) was given in the last two weeks. The bladder functions were evaluated by performing voiding behavior assays, cystometry and in vitro bladder contractions. MGO intake markedly elevated the levels of MGO and fluorescent AGEs in serum and reduced the mRNA expression and activity of glyoxalase (Glo1) in bladder tissues. Glucose levels were unaffected among groups. MGO intake also increased the urothelium thickness and collagen content of the bladder. Void spot assays in conscious mice revealed an increased void volume in MGO group. The cystometric assays in anesthetized mice revealed increases of basal pressure, non-voiding contractions frequency, bladder capacity, inter-micturition pressure and residual volume, which were accompanied by reduced voiding efficiency in MGO group. In vitro bladder contractions to carbachol, α,ß-methylene ATP and electrical-field stimulation were significantly greater in MGO group. Metformin normalized the changes of MGO and AGEs levels, Glo1 expression and activity, urothelium thickness and collagen content. The MGO-induced voiding dysfunction were all restored by metformin treatment. Our findings strongly suggest that the amelioration of MGO-induced voiding dysfunction by metformin relies on its ability to scavenger MGO, preventing its accumulation in blood.

RESUMEN

PURPOSE: Despite the establishment of radical surgery for therapy of cervical cancer, data on quality of life and patient-reported outcomes are scarce. The aim of this retrospective cohort study was to evaluate bladder, bowel and sexual function in women who underwent minimally invasive surgery for early-stage cervical cancer. METHODS: From 2007-2013, 261 women underwent laparoscopically assisted radical vaginal hysterectomy (LARVH = 45), vaginally assisted laparoscopic or robotic radical hysterectomy (VALRRH = 61) or laparoscopic total mesometrial resection (TMMR = 25) and 131 of them completed the validated German version of the Australian Pelvic Floor Questionnaire (PFQ). Results were compared with controls recruited from gynecological clinics (n = 24) and with urogynecological patients (n = 63). RESULTS: Groups were similar regarding age, BMI and parity. The TMMR group had significantly shorter median follow-up (16 months versus 70 and 36 months). Postoperatively, deterioration of bladder function was reported by 70%, 57% and 44% in the LARVH, VARRVH and TMMR groups, respectively (p = 0.734). Bowel function was significantly worse after TMMR with a higher deterioration rate in 72 versus 43% (LARVH) and 47% (VARRVH) with a correspondingly higher bowel dysfunction score of 2.9 versus 1.5 and 1.8, respectively and 1.8 in urogynaecological patients. Sexual dysfunction was common in all surgical groups. 38% considered their vagina too short which was significantly associated with deep dyspareunia. Compared with controls, surgical groups had significantly increased PFQ scores. CONCLUSION: Pelvic floor dysfunction commonly deteriorates and negatively impacts on quality of life after minimally invasive radical hysterectomy, especially bowel function after TMMR. Pelvic floor symptoms should routinely be addressed pre- and postoperatively.

RESUMEN

PURPOSE: Parasacral transcutaneous electrical nerve stimulation has been used to manage lower urinary tract symptoms refractory to standard urotherapy. Nevertheless, its actual effectiveness in treatment of bladder and bowel dysfunction remains to be established. We sought to evaluate the effectiveness of parasacral transcutaneous electrical nerve stimulation in the treatment of children with bladder and bowel dysfunction. MATERIALS AND METHODS: This was a randomized clinical trial conducted with children and adolescents of 5-17 years of age diagnosed with bladder and bowel dysfunction. Patients with neurological or anatomical abnormalities of urinary or digestive tracts, those unable to attend treatment sessions 3 times a week, individuals with diabetes mellitus or diabetes insipidus and those using anticholinergic drugs or laxatives were excluded from the study. The sample was divided into 2 groups: a control group submitted to standard urotherapy plus sham electrotherapy applied to the scapular region and a treatment group submitted to urotherapy plus parasacral transcutaneous electrical nerve stimulation. All the patients were submitted to 3, 20-minute electrotherapy (parasacral transcutaneous electrical nerve stimulation or sham) sessions/week for a total of 20 sessions. RESULTS: Forty patients were evaluated, 20 in the control group and 20 in the treatment group. Mean age (±standard deviation) was 8.4±2.8 years and 52.5% were male. In 15 patients (37.5%), rectal diameter was ≥3 cm. Lower urinary tract symptoms improved in both groups following treatment, with no statistically significant differences in Dysfunctional Voiding Scoring System score, lower urinary tract symptoms or uroflowmetry patterns between the groups. Intragroup evaluation showed a significant improvement in enuresis in the treatment group. There was a significant improvement in functional constipation post-intervention in treatment group compared to control group (70% vs 20%, p=0.004). CONCLUSIONS: Parasacral transcutaneous electrical nerve stimulation is effective for treatment of bladder and bowel dysfunction in children and adolescents, particularly insofar as functional constipation is concerned.

RESUMEN

PURPOSE: The purpose of this study was to determine the prevalence of bladder lesions diagnosed during transurethral resection of the prostate (TURP), to identify the associated risk factors, and to correlate the macroscopic descriptions with the pathological findings. METHODS: This was a single-center retrospective case series conducted at a hospital in the city of São Paulo, Brazil. We reviewed the medical and surgical records of patients who underwent TURP between January 2012 and December 2017. RESULTS: The final sample comprised 513 patients, with a mean age of 70.8 years. Bladder lesions were identified during TURP in 109 (21.2%) of the patients, and 90 of those lesions were submitted for pathological examination. The most common macroscopic finding was bullous edema, which was seen in 57 (63.3%) of the 90 lesions examined. The pathological analysis revealed chronic cystitis in 61 lesions (67.8%) and malignant lesions in 16 (17.8%). Of the 57 lesions described as bullous edema, 5 (8.8%) were found to be malignant. CONCLUSIONS: Alterations in the bladder mucosa appear to be more common among elderly patients who use an indwelling urinary catheter for a prolonged period and among patients with recurrent urinary tract infections. In addition, the risk of a bladder lesion being malignant is apparently higher in current and former smokers than in never smokers. Our findings suggest that at-risk patients should undergo biopsy or resection of incidental bladder lesions even if those lesions seem to be benign, due to the low level of agreement between the visual analysis and the pathological examination.

RESUMEN

PURPOSE: To evaluate the expression of urinary biomarkers of inflammation and tissue remodeling in patients with BPH undergoing surgery and evaluate the association of biomarkers with postoperative urodynamic outcomes MATERIALS AND METHODS: We analyzed urine samples from 71 patients treated with TURP from 2011 to 2017. Urinary levels of epidermal growth factor (EGF), matrix-metalloproteinase-1 (MMP-1), interleukin-6 (IL-6), nerve growth factor (NGF) and monocyte-chemoattractant protein-1 (MCP-1) (by commercial ELISA kit) were measured, adjusted by urinary creatinine (Cr) and analyzed according to patients clinical and urodynamic characteristics (baseline and 12-month postoperative urodynamic) RESULTS: MMP-1/Cr levels were significantly higher among subjects with higher detrusor pressure on preoprative urodynamic. MCP-1/Cr levels were significantly higher amongs subjects with preoperative DO. Preoperative levels of NGF/Cr (0.13 vs 0.08, p = 0.005) and MMP-1/Cr (0.11 vs 0.04, p = 0.021) were predictors of persistent DO 12 months after surgery. The following factors were shown to be useful for predicting the persistence of DO in the postoperative period: NGF/Cr, with an AUC of 0.77 (95% CI 0.62-0.92) (p = 0.006), and MMP-1/Cr, with an AUC of 0.72 (95% CI 0.56-0.88) (p = 0.022). CONCLUSIONS: MMP-1/Cr was associated with higher detrusor pressure and MCP-1/CR with DO. NGF/Cr and MMP-1/Cr were shown to be predictors of persistent postoperative DO.

RESUMEN

ABSTRACT Objective: Cystectomy with urinary diversion is the gold standard for muscle invasive bladder cancer. It also may be performed as part of pelvic exenteration for non-urologic malignancy, neurogenic bladder dysfunction, and chronic conditions that result in a non-functional bladder (e.g., interstitial cystitis, radiation cystitis). Our objective is to describe the surgical technique of urinary diversion using large intestine as a conduit whilst creating an end colostomy, thereby avoiding a primary bowel anastomosis and to show its applicability with respect to urologic conditions. Materials and Methods: We retrospectively reviewed five cases from a single institution that utilized the described method of urinary diversion with large intestine. We describe operative times, hospital length of stay (LOS), and describe post-operative complications. Results: Five patients with a variety of urologic and oncologic pathology underwent the described procedures. Their operative times ranged from 5 hours to 11 hours and one patient experienced a Clavien III complication. Conclusion: We describe five patients who underwent this procedure for various medical indications, and describe their outcomes, and believe dual diversion of urinary and gastrointestinal systems with colon as a urinary conduit to be an excellent surgical option for the appropriate surgical candidate.

RESUMEN

ABSTRACT Objective: To identify and describe the protocols and clinical outcomes of urotherapy interventions in children and adolescents with bladder bowel dysfunction. Method: Systematic review carried out in June 2018 on Medical Literature Analysis and Retrieval System Online (MEDLINE), Cumulative Index to Nursing and Allied Health Literature (CINAHL),Excerpta Medica dataBASE (EMBASE), Scientific Electronic Library Online (SciELO), Cochrane Library, and PsycInfo databases. Clinical trials and quasi-experimental studies carried out in the last ten years in children and/or adolescents with bladder and bowel symptoms and application of at least one component of urotherapy were included. Results: Thirteen clinical trials and one quasi-experimental study were included, with moderate methodological quality. The heterogeneity of the samples and of the methodological design of the articles prevented the performance of a meta-analysis. The descriptive analysis through simple percentages showed symptom reduction and improvement of uroflowmetry parameters. The identified urotherapy components were: educational guidance, water intake, caffeine reduction, adequate voiding position, pelvic floor training, programmed urination, and constipation control/management. Conclusion: This review indicates positive results in terms of symptom reduction and uroflowmetry parameter improvement with standard urotherapy as the first line of treatment for children and adolescents with bladder bowel dysfunction. It is recommended that future studies bring contributions regarding the frequency, number, and time of urotherapy consultations.


RESUMO Objetivo: Identificar e descrever os protocolos e desfechos clínicos das intervenções de uroterapia em crianças e adolescentes com disfunção vesical e intestinal. Método: Revisão sistemática realizada em junho de 2018 nas bases Medical Literature Analysis and Retrieval System Online (MEDLINE), Cumulative Index to Nursing and Allied Health Literature (CINAHL), Excerpta Medica dataBASE (EMBASE), Scientific Electronic Library Online (SciELO), Cochrane Library e PsycInfo. Foram incluídos ensaios clínicos e estudos quase-experimentais dos últimos 10 anos, em crianças e/ou adolescentes com sintoma urinário e intestinal e aplicação de no mínimo um componente de uroterapia. Resultados: 13 ensaios clínicos e 1 estudo quase-experimental foram incluídos, sendo a qualidade metodológica moderada. A heterogeneidade da amostra e de delineamento metodológico dos artigos impediu a realização de meta-análise. A análise descritiva por meio de percentual simples demonstrou redução dos sintomas e melhora dos parâmetros de urofluxometria. Os componentes de uroterapia identificados foram: orientação educacional, ingestão hídrica, redução de cafeína, posicionamento adequado para eliminação, treinamento do assoalho pélvico, micção programada e controle/manejo da constipação. Conclusão: Esta revisão sinaliza resultados positivos em termos de redução de sintomas e melhora nos parâmetros de urofluxometria com aplicação de uroterapia padrão como primeira linha de tratamento nos casos de crianças e adolescentes com disfunção vesical e intestinal. Recomenda-se que estudos futuros tragam contribuições no que tange a frequência, número e tempo para as consultas de uroterapia.
