Influence of ATOMS implant on the voiding phase of patients with post-prostatectomy urinary incontinence.

OBJECTIVE: To assess changes in voiding phase, especially urethral resistance after post-prostatectomy urinary incontinence (PPI) treatment with the Adjustable TransObturator Male System (ATOMS). MATERIAL AND METHODS: A longitudinal prospective study was performed on 45 men treated with ATOMS for PPI, with the intention to evaluate the changes produced by the implant on the voiding phase. Patients with preoperative urodynamic study were offered postoperative urodynamic evaluation, and both studies were compared. The following urodynamic date were evaluated: maximum voiding detrusor pressure, detrusor pressure at maximum flow rate, maximum flow rate (Qmax), voiding volume, post-void residue, bladder outlet obstruction index (BOOI), urethral resistance factor (URA), and bladder contractility index (BCI). The statistical analysis used were the mean comparison test for dependent groups (Student's t test) for parametric variables and the Wilcoxon test for non-parametric variables. The signification level was set at 95% bilateral. RESULTS: A total of 37 patients (82.2%) used zero pads/day at the time of urodynamic postoperative evaluation and pad-test evolved from 592 ± 289 ml baseline to 25 ± 40 ml (p = 0.0001). Significant differences were observed in Qmax (15 ± 8.3 before and 11 ± 8.3 after surgery; p = 0.008), voiding volume (282 ± 130.7 before and 184 ± 99.92 after surgery). BOOI (-12 ± 23.9 before and -2 ± 21.4 after surgery; p = 0.025) and BCI (93 ± 46.4 before and 76 ± 46.0 after surgery; p = 0.044). In no case did we observe postoperative bladder outlet obstruction, according to URA parameter below 29 cm H2 O in all cases. There was not a significant variation either in post-void urinary residual volume (15 ± 47.4 before and 14 ± 24.2 after surgery, p = 0.867). CONCLUSIONS: The ATOMS implant induces a decrease of Qmax, voided volume, and bladder contractility and an increase of BOOI. However, our findings suggest that ATOMS device does not cause bladder outlet obstruction.

Do voiding urodynamic parameters predict the success of adjustable transobturator male system (ATOMS) to treat postprostatectomy urinary incontinence?

OBJECTIVE: To evaluate whether urodynamic voiding risk factors can be predictive of failure of postprostatectomy urinary incontinence (PPI) treatment with adjustable transobturator male system (ATOMS). MATERIALS AND METHODS: We carried out a longitudinal study on 77 males treated for PPI with ATOMS. Patients were submitted preoperatively to a urodynamic study. The postoperative outcome was checked by pad-test. Treatment success was defined as daily pad-test below 10 mL. Statistical analysis used were Fisher exact test, χ2 lineal by lineal test, Student t test, and logistic regression analysis. The signification level was set at 95% bilateral. RESULTS: Treatment was successful in 54 patients (70%) achieving continence. The urodynamic parameters that related to postoperative continence outcome were the cystometric bladder capacity (direct relationship with continence (P = .019), type of voiding (more probability to achieve continence in patients who voided voluntarily followed by patients with involuntary voiding and abdominal straining voiding) (P = .034), Bladder Outlet Obstruction Index (BOOI) (inversely related with continence) (P = .025), and maximum voiding abdominal pressure (inversely related with continence) (P = .049). Multivariate analysis showed that cystometric bladder capacity (odds ratio [OR], 1.01; confidence interval [CI], 1.02-1.00), BOOI (OR, 0.97; CI, 0.99-0.94), and maximum abdominal bladder pressure (OR, 0.97; CI, 0.98-0.94) were independent risk factors to predict treatment success after ATOMS implant. CONCLUSIONS: The study of functional voiding parameters is useful to know the risk factors that influence postoperative outcome of PPI with ATOMS device. These findings could be of primary importance to facilitate optimum patient selection for this implant and therefore improve operative results.

Long-term outcome of adjustable transobturator male system for stress urinary incontinence in the Iberian multicentre study.

AIM: The aim of this study is to evaluate long-term durability and effectiveness of the adjustable transobturator male system (ATOMS). MATERIALS AND METHODS: The retrospective multicenter Iberian ATOMS study (n = 215) was updated to evaluate long-term continence status, complications, explants, and secondary treatments. Mean follow-up from surgery to March 2020 was 60.6 ± 18.4 months (range, 39-91). Eleven patients deceased of an unrelated causes. Kaplan-Meier curves were performed to evaluate device durability and incontinence free of recurrence interval. The multivariate analysis defined the population at risk of device explant. RESULTS: A total of 155 patients were dry at the last follow-up visit (72.1%); 99 (46%) used no pads and 56 (26%) used a security pad/day with urine loss less than 10 mL; 96% of dry patients after adjustment remained free of incontinence 1 year later, 93.6% 2 years later, 91.1% 3 years later, 89.2% 5 years later, and 86.7% 8 years later. Complications during follow-up occurred in 43 of 215 (20%). In total, 25 (11.6%) devices were explanted and causes were inefficacy 11 (44%), inefficacy and pain 3 (12%), port erosion 10 (40%), and wound infection 1 (4%). The secondary implant was performed in 11 (5.1%) cases, 6 artificial urinary sphincter and 5 repeated ATOMS. Time to explant was associated to complications (P < .0001), baseline stress urinary incontinence (SUI) severity (P = .01), and former irradiation (P = .03). Multivariate analysis revealed complications (hazard ratio [HR] = 8.71; 3.83-19.82), baseline SUI severity (>5 compared to 1-2 pads/day; HR = 14.9; 1.87-125), and irradiation before ATOMS (HR = 2.26; 1.02-5.18) predicted earlier ATOMS explant. Three cases received radiation after implant without complication. CONCLUSIONS: ATOMS device is efficacious and safe in the long term. Determinants for device explant include complications, baseline severity of incontinence, and previous irradiation. Currently, the durability of the device after 5 years is reassuring.

Effect of pelvic organ prolapse repair on detrusor overactivity in women following incontinence surgery: A multivariate analysis.

AIMS: To determine the effect of pelvic organ prolapse (POP) repair on post-operative detrusor overactivity (DO) in women who have underwent incontinence surgery, using multivariate analysis. METHODS: A retrospective study was carried out on a cohort of 105 women who underwent incontinence surgery. In 39 of the patients this surgery was associated with pelvic organ prolapse repair. Clinical and urodynamic data were collected pre- and 3 months post-operatively. A multivariate statistical analysis was performed to detect confounding factors which could influence on the risk factors associated with post-operative detrusor overactivity. RESULTS: On univariate analysis, the following pre-operative factors were associated with post-operative detrusor overactivity: symptomatic mixed urinary incontinence, rectocele, detrusor overactivity, voided volume on free uroflowmetry, maximum cystomanometric capacity, and performing concomitant pelvic organ prolapse repair. Multivariate analysis, by means of confounding factors elimination, revealed that only pre-operative rectocele and detrusor overactivity were independent risk factors. CONCLUSIONS: The pelvic organ prolapse repair acts as a confounding factor. Women with a pre-operative rectocele and detrusor overactivity are on a greater risk to develop post-operative detrusor overactivity and, therefore, they should be informed.

Risk factors to develop autonomic dysreflexia during urodynamic examinations in patients with spinal cord injury.

AIMS: The risk factors for developing autonomic dysreflexia (AD) during urodynamic (UD) examination in patients with spinal cord injury (SCI) above Th6 still remain unclear. The main goal of our study is to investigate the risk factors that could be associated with AD in these particular patients. DESIGN: Cross sectional survey. SUBJECT AND METHODS: The study was carried out in 83 patients with SCI above Th6 who were submitted to our center for a UD examination. AD was defined as a rise in systolic blood pressure above 15 mm Hg with a pulse rate below 60 beats per minute. RESULTS: The prevalence rate of AD among our patients was 54%. Univariate analysis of our study showed the following risk factors: patient's age, SCI completeness, traumatic etiology, indwelling catheter, presence of chills or sweating, anticholinergic treatment, maximum detrusor voiding pressure, detrusor pressure at maximum flow rate, detrusor external sphincter dyssynergia, and bladder outlet obstruction. Using multivariate logistic regression, we found that there are only two independent risk factors: patient's age equal to or above 45 years of age (OR = 10.995) and maximum detrusor voiding pressure equal to or above 31 cm H2 O (OR = 3.879). CONCLUSIONS: According to our results, the patient's age and maximum detrusor voiding pressure should be considered at the time of performing a UD examination in order to prevent the sudden onset of AD in patients with SCI above Th6.

Post Pelvic Radiotherapy Affectation of the Lower Urinary Tract Peripheral Innervation in Men.

INTRODUCTION: The periurethral electromyography (EMGs) alterations in men who underwent pelvic radiotherapy (RT), either isolated or combined with surgery, have not been frequently described in the literature. OBJECTIVE: The study aimed to compare the EMG's data in men undergoing RT versus the non-irradiated control group. MATERIAL AND METHODS: The study included 61 consecutive males, who had undergone RT (27 of them had been operated) and 99 control consecutive patients who underwent a retrospective assessment. The EMGs were performed using a concentric electrode needle perineally, localizing the sphincter by visual and auditory signal (electromyograph MMS Solar Active). RESULTS: 14.8% denervation, 62.9% reinnervation, 14.9% denervation + reinnervation and 7.4% EMG normal. The age (p < 0.001) and neurogenic bladder data (p < 0.001) are risk factors. The smaller the prostate size (obtained by rectal examination) post-RT, the more the chance for an abnormal EMG (p < 0.001). The fact of having had received RT (p < 0.001) is the only risk factor. CONCLUSION: RT produces lesions over the pudendal nerve, showing denervation even in late periods. The surgery did not behave as a risk factor.

Psychological impact and sexual dysfunction in men with and without spinal cord injury.

INTRODUCTION: The World Health Organization recognizes sexual health as a fundamental right that should be guaranteed to all individuals. Sexual dysfunction affects various aspects in the lives (physical, psychic, and social) of affected persons. AIMS: To assess the different types of sexual dysfunction, the quality of life (QOL), depression, anxiety, and levels of self-esteem observed in 165 men with sexual dysfunction, both with and without spinal cord injury (SCI). METHODS: Case control study of 85 men with SCI and sexual dysfunction, and 80 men without SCI that have sexual dysfunction. MAIN OUTCOMES MEASURES: The Sexual Health Evaluation Scale, the Fugl-Meyer Life Satisfaction Questionnaire scale, the Hospital Anxiety and Depression Scale, the Evaluation of the Sexual Health Scale, and Rosenberg's Self-esteem Scale were all used for data collection. RESULTS: Of the members in group A (with SCI), 89.4% (76) showed erectile dysfunction, and 75.2% (64) reported anejaculation. In group B (without SCI), 75 (96.8%) showed erectile dysfunction, and 58.7% (47) had disorders of sexual desire. In group A, 16.47 % (14) showed signs of depression, and 35.3% (30) had signs of anxiety. In group B, 30% (24) had elevated scores regarding depression, and 48.75% (39) had high scores for anxiety. All of the participants reported a high general QOL and a high satisfaction with their QOL but reported that their satisfaction with their sexual lives was only at the acceptable level. Social QOL is significantly higher in the SCI group (t Student P=0.031). The QOL, self-esteem, and anxiety and depression levels are significantly correlated. CONCLUSIONS: Men with sexual dysfunction strive to adapt to their situations, with the relationship between the type of sexual dysfunction and the QOL, mood (depression), and self-esteem all being important considerations. Sexuality and employment status are the areas where men with spinal cord injuries report less satisfaction.

Study of the prevalence and interobserver reproducibility of radiologic images suggestive of urethral diverticula in men with spinal cord injury.

OBJECTIVES: To determine the prevalence of radiologic images suggestive of urethral diverticula (UD) in men with spinal cord injury (SCI) and to study the interobserver diagnostic reproducibility. METHODS: Radiological studies (i.e. voiding cystourethrography and retrograde urethrography) performed over 1 year on men with SCI were independently reviewed by 3 researchers (1 urologist and 2 radiologists). RESULTS: The prevalence of UD was found to be between 4.2 and 9.8% of the patients, the higher figure obtained when including also the doubtful images. The kappa index of agreement between the researchers was low (between 0.15 and 0.40). The factors that significantly influenced agreement were localization in the prostatic urethra (p = 0.021), localization in the penile urethra (p = 0.000) and fusiform morphology (p = 0.004). Logistic regression analysis showed that the variables that independently influenced diagnostic agreement were the following: localization in the penile urethra (in favor of agreement) and fusiform morphology (against agreement). CONCLUSIONS: Radiologic images suggestive of UD constitute a frequent finding in men with SCI and raise important diagnostic problems.

Update on Adjustable Trans-Obturator Male System (ATOMS) for Male Incontinence after Prostate Cancer Surgery.

(1) Background: The adjustable trans-obturator male system (ATOMS) is a surgical device developed to treat post-prostatectomy incontinence (PPI) after prostate cancer treatment. We review the current literature on this anti-incontinence device with the intention of assessing the effectiveness, safety and duration of the silicone-covered scrotal port (SSP) ATOMS, the only generation of the device that is currently available. (2) Material and Methods: Non-systematic literature review is performed. Forty-eight full-text articles are assessed for eligibility. Case reports, expert opinions or commentaries without specific data reported (n = 6), studies with patients who underwent intervention before 2014 (IP or SP ATOMS; n = 10), and studies with incontinence after transurethral resection of the prostate (TUR-P; n = 2) are excluded for analysis. Thirty studies with SSP ATOMS are included in a qualitative synthesis that incorporates systematic reviews (n = 3), articles partially overlapping with other previously published studies (e.g., follow-up or series updates; n = 9), and studies focusing on specific populations (n = 8). Only articles revealing outcomes of SSP ATOMS were included in the quantitative synthesis of results (n = 10). (3) Results: the pooled data of 1515 patients from the 10 studies with SSP ATOMS confirmed very satisfactory results with this device after adjustment: dry rate: 63-82%, improved rate: 85-100%, complication rate: 7-33%, device infection rate: 2.7-6.2% and explant rate: 0-19%. The durability of the device is reassuring, with 89% of devices in place 5 years after implantation. (4) Conclusion: Despite the absence of randomized controlled studies, the literature findings confirm results of SSP ATOMS appear equivalent to those of artificial urinary sphincters (AUSs) in terms of continence, satisfaction and complications, but with a lower rate of revision in the long-term. A prospective study identified that patients with daily pad test results <900 mL and a Male Stress Incontinence Grading Scale (MSIGS) of not 4 (i.e., early and persistent stream or urine loss) are the best candidates. Future studies centered on the elder population at higher risk of impaired cognitive ability and in patients including radiation as prostate cancer treatment are needed.

Factors Influencing Postoperative Overactive Bladder after Adjustable Trans-Obturator Male System Implantation for Male Stress Incontinence following Prostatectomy.

We aimed to determine the risk factors for postoperative overactive bladder (OAB) in patients treated with an adjustable trans-obturator male system (ATOMS) for stress incontinence after radical treatment of prostate cancer. A prospective study was performed on 56 patients implanted with an ATOMS for PPI. Clinical and urodynamic information was recorded before and after ATOMS implantation. We built a multivariate model to find out the clinical and urodynamic factors that independently influenced postoperative OAB and the prognostic factors that influenced the efficacy of medical treatment of OAB. We found that the clinical risk factors were the preoperative intensity of urinary incontinence (number of daily pads used and amount of urinary leakage), International Consultation on Incontinence Questionnaire (ICIQ) score, postoperative number of ATOMS adjustments, final cushion volume, and incontinence cure. The urodynamic data associated with OAB were cystometric bladder capacity, voided volume, volume at initial involuntary contraction (IC), maximum flow rate, bladder contractility index (BCI), and urethral resistance (URA). The prognostic factors for the efficacy of oral treatment of OAB were the volume at the first IC (direct relationship) and the maximum abdominal voiding pressure (inverse relationship). The multivariate model showed that the independent clinical risk factors were the daily pad count before the implantation and the ICIQ score at baseline and after treatment. The independent urodynamic data were the volume at the first IC (inverse relationship) and the URA value (direct relationship). Both predictive factors of treatment efficacy were found to be independent. Detrusor overactivity plays an important role in postoperative OAB, although other urodynamic and clinical factors such as the degree of urethral resistance and abdominal strength may influence this condition.

Compression or obstruction: Prospective analysis of the function of the Adjustable Transobturator Male System (ATOMS) based on preand postoperative urodynamic data.

INTRODUCTION: This analysis, based on pre- and postoperative urodynamic data, is the first to elucidate the influence of the Adjustable Transobturator Male System (ATOMS, A.M.I. GmbH, Feldkirch, Austria) on the lower urinary tract and disclose possible obstructive properties. METHODS: A prospective study was performed in patients who had stress urinary incontinence and were scheduled for ATOMS implantation after radical prostatectomy. Apart from continence assessment (24-hour pad test, International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form [ICIQ-SF]), urodynamic testing was done with International Continence Society (ICS)-standardized pressure-flow analysis before and after ATOMS implantation/adjustment. The Wilcoxon signed-rank test was used for statistical analysis. RESULTS: The analysis included 12 consecutive patients from two centers (mean age 69 years) with a mean followup of 246 days. Median urine leakage dropped from 240 (72-1250) to 70 (0-700) g/24 hours postoperatively, with a pad reduction of 4 to 0.9 pads/ day. Pressure-flow analysis revealed a significant change only in the bladder outlet obstruction index (BOOI). The bladder contractility index, intravesical pressure conditions, and uroflowmetry were not significantly affected. None of the patients showed de novo obstruction postoperatively in the ICS analysis. CONCLUSIONS: The ATOMS significantly increases the BOOI in conjunction with good continence results. However, no case reached pathological level according to the BOOI and thus there is no potential danger to the lower urinary tract or urethral integrity.

ATOMS (Adjustable Trans-Obturator Male System) in Patients with Post-Prostatectomy Incontinence and Previously Treated Urethral Stricture or Bladder Neck Contracture.

(1) Background: Male stress incontinence in patients with previously treated urethral or bladder neck stricture is a therapeutic challenge. The efficacy and safety of the adjustable trans-obturator male system (ATOMS) in these patients is unknown. (2) Methods: All patients with primary ATOMS implants in our institution between 2014 and 2021 were included. The outcomes of patients with previously treated urethral or bladder neck stricture (≥6 months before ATOMS implant) and stable 16Ch urethral caliber were compared to those without a history of stricture. The primary endpoint was the dry patient rate, defined as the pad test ≤ 20 mL/day, and complication rate, including device removal. The secondary variable was self-perceived satisfaction using the Patient Global Impression of Improvement (PGI-I) scale. Wilcoxon rank sum test, Fisher's exact test and logistic regression were performed. (3) Results: One hundred and forty-nine consecutive patients were included, twenty-one (14%) previously treated for urethral or bladder neck stricture (seven urethroplasty, nine internal urethrotomy and five bladder neck incision). After ATOMS adjustment, 38% of the patients with treated stricture were continent compared to 83% of those without (p < 0.0001). After weighted matched observations using propensity score pairing, the proportion of continent patients without a previous stricture was 56% (p = 0.236). Complications occurred in 29% of the patients with stricture and in 20% of those without (p = 0.34). The severity of the complications was distributed evenly among the groups (p = 0.42). Regarding self-perceived satisfaction with the implant, 90% of the patients with stricture perceived the results satisfactorily (PGI-I 1−3) compared to 97% of the rest (p = 0.167). Stricture was associated with radiotherapy (p < 0.0001) and time from prostatectomy to implantation (p = 0.012). There was a moderate correlation between previous stricture and the severity of incontinence, both evaluated according to the 24-h pad test (Rho = 0.378; p < 0.0001) and the ICIQ-SF questionnaire (Rho = 0.351; p < 0.0001). Multivariate analysis for the factors predictive of failure after ATOMS adjustment revealed previous stricture (OR 4.66; 95% CI 1.2−18.87), baseline 24-h pad test (per 100 mL, OR 1.28; 95% CI 1.09−1.52) and final cushion volume (per mL, OR 1.34; 95% CI 1.19−1.55). This model predicted dryness with an AUC of 92%. After the PSMATCH procedure using a propensity score, the model remained unchanged, with the previous stricture (OR 8.05; 95% CI 1.08−110.83), baseline 24-h pad test (per 100 mL, OR 1.53; 95% CI 1.15−2.26) and final cushion volume (per mL, OR 1.45; 95% CI 1.17−2) being independent predictors and an AUC of 93%. (4) Conclusions: ATOMS can be used to treat male stress incontinence in patients with a history of stricture, although the effectiveness of the device is reduced. On the other hand, the security and perceived satisfaction were equivalent for both groups.

[Urodynamic AUR in Guillain-Barré syndrome post-infection by coronavirus Sars-CoV-2. A bibliographic review.] / Urodinámica de la RAO en el síndrome De Guillain-Barré post-infección por coronavirus Sars-Cov-2. Revisión bibliográfica.

INTRODUCTION AND OBJECTIVE: The SARS-CoV-2 coronavirus infection has beenassociated with the development of the novo genitourinarysymptoms and neurological symptomssecondary to peripheral nervous system damage.One of the neurological pathologies described associatedwith the infection has been Guillain-Barrésyndrome (GBS).

[Prevalence and risk factors for lower urinary tract symptoms after robotic sacrocolpopexy.] / Prevalencia y factores de riesgo de síntomas del tracto urinario inferior post sacrocolpopexia robótica.

OBJECTIVES: To analyse the outcomes of Robotic Sacrocolpopexy (RSC) on resolution of Lower urinary tract Symptoms (LUTS) associated to pelvic organ prolapses (POP) and to determine the risk factors for preoperative LUTS presence. MATERIAL AND METHODS: A longitudinal study was carried out on 51 females mean aged (± standard deviation) 66 ± 9 years, who underwent RSC. A preoperative evaluation was made on the degree and type of POP, and the presence of the LUTS stress urinary incontinence (SUI), urgency and voiding difficulty. An urodynamic study was also performed. The presence of LUTS was evaluated again six months after being operated on. The statistical test used were the Mcnermar test for dependent variables, the Fisher's exact test and the t Student's mean comparison test. The signification level was set at p < 0.05 bilaterally. RESULTS: A significate decrease of postoperative SUI and voiding difficult was observed. However, urgency did not significantly diminish. Transobturatice free-tension mesh ( TOT) implementation in patients with evident or occult (with POP reduction) urodynamic SUI significantly decreased the prevalence of symptomatic SUI. The only significate risk factor was the preoperative presence of urgency regarding its postoperative prevalence. CONCLUSIONS: Robotic sacrocolpopexy significantly improves postoperative voiding difficult. TOT implement in patients with positive POP reduction test is useful to prevent postoperative symptomatic SUI.

OBJETIVOS: Analizar los resultados de la sacrocolpopexia laparoscópica (LSC) robótica en la resolución de los síntomas funcionales del tracto urinario inferior (LUTS) asociados a los prolapsos pélvicos (POP) y determinar los posibles factores de riesgo para la presencia de LUTS postoperatorios.MATERIAL Y MÉTODOS: Se realizó un estudio longitudinal de 51 mujeres de edad media (± desviación típica) 66 ± 9 años intervenidas de LSC robótica por POP. Preoperatoriamente se evaluó el grado y tipo de POP, la presencia de los LUTS incontinencia urinaria de esfuerzo (SUI), y urgencia y dificultad miccionales, y se realizó un estudio urodinámico. A los 6 meses de la cirugía se volvió a evaluar la presencia de LUTS. Los test estadísticos utilizados fueron el test de Mcnemar para variables dependientes y el test exacto de Fisher y la prueba de comparación de medias de la t de Student para variables independientes. El nivel de significación se fijó en p < 0,05 bilateral. RESULTADOS: Se comprobó una disminución postoperatoria significativa de la SUI y la dificultad miccional, pero no de la urgencia miccional. La implantación de una malla transobturatiriz (TOT) en pacientes con incontinencia de esfuerzo urodinámica evidente o Post reducción del POP (incontinencia de esfuerzo oculta) disminuyo significativamente la prevalencia de SUI sintomática postoperatoria. El único factor de riesgo significativo fue la presencia preoperatoria de urgencia miccional respecto a la prevalencia postoperatoria de ese LUTS. CONCLUSIONES: La LSC robótica mejora significativamente la dificultad miccional preoperatoria. La implantación de un TOT en pacientes con test de reducción del POP positivo es útil para prevenir la SUI sintomática postoperatoria.

[High dynamic risk cystoceles]. / Cistoceles de alto riesgo urodinamico.

OBJECTIVES: To assess the bladder compliance in a series of cystoceles referred for urodynamic study. METHODS: Retrospective study of a series of patients with cystocele undergoing medical history, videurodynamic study, pelvic MRI and lower urinary tract, urological ultrasound and cystoscopy. We Excluded cases with neurogenic dysfunction and urinary infection. The terminology followed the criteria of the ICS, if not specified otherwise. The series includes 3333 cases of cystocele 616 of which are grade III cystocele. There were 3 cases with low bladder compliance; this is 0.0009% of total (1:1000) and 0.5% of grade III cystocele (1:200) RESULTS: All cases of cystocele whith low compliance were associated with feeling of a bulk in the vagina and functional symptoms of lower urinary tract(LUTS). No urinary incontinence was related to cough. These patients also showed urodynamic alterations in the voiding phase, type hypo / acontractile detrusor and postvoid residual. The patients were subjected to various techniques of abdominal and transvaginal cystocele repair (with preventive anti-incontinence surgery), getting a vagina bulk disappearance, improvement of symptoms of lower urinary tract function, normalization of bladder compliance and detrusor contractility, with elimination of the postvoid residual. CONCLUSIONS: Although they are not frequent, high-risk cystoceles should be discarded in high-grade cystocele that apart from low bladder accommodation, have a hipo/acontractile detrusor and postvoid residual. Surgical correction of cystocele not only reduces the bulk and LUTS, but normalizes urodynamic alterations.

[Correlation of bladder thickness on ultrasound with clinical and urodynamic data in symptomatic benign prostatic hyperplasia]. / Correlación del grosor ecográfico vesical con los datos clínicos y urodinámicos en la hiperplasia benigna de próstata (HBP) sintomática.

OBJECTIVES: Our objective is to verify the diagnostic usefulness of ultrasound measurement of the thickness of the bladder wall, and the correlation with clinical/ urodynamic findings in patients with symptomatic BPH. METHODS: We performed a prospective cross-sectional study (cross-sectional study '') in a series of 74 males (age chi= 72.4 S = 7.1 (56-84 years) with symptomatic BPH. Patients completed the IPSS and determined the plasma level of PSAt (ng / ml). Before performing the urodynamic study, was determined by transabdominal ultrasonography (3.5 MHz transducer): prostate volume (cc) by the ellipsoid formula, and bladder wall thickness (mm) measured on the anterior bladder wall. Statistical analysis was performed using ANOVA, the Pearson correlation, and ROC curve. RESULTS: It was a significant correlation of the sonographic thickness of the bladder wall with the IPSS (p = 0001, r = 0.38) (parameter in turn highly correlated with prostate volume and PSA (p = 0.01, r = 0.62)), as well as the detrusor hyperactivity (p = 0.03, r =0.21), cut off ROC curve: 3.85 mm. Instead, it was not shown a significant correlation between the sonographic thickness of the bladder wall and the urodynamic diagnosis of obstruction (Abrams and number Griffths p = 0223, r = 0.14) or the detrusor contractile power, measured in power at peak flow (Pw) (p = 0642 r =- 0.55), nor with age (p = 0303, r = 0.12). Neither correlation was observed with other non-invasive urodynamic measures (the maximum urinary flow flowmetry (p = 0318, r = 0.12) and percentage postmicturition residual (p = 0696, r = 0.05)). CONCLUSIONS: The ultrasound measurement of bladder wall thickness, although it has not proved useful ness in our series in the diagnosis of the voiding phase (lower urinary tract obstruction and detrusor contractility impairment), on the contrary it can be introduced as a diagnostic technique for non-invasive studies in the alterations of the filling phase, in the form of detrusor hyperactivity in also patients with symptomatic BPH, and present a significant correlation with prostate growth.

Large study (283 women) on the effectiveness of Manosar®: 2 g of d-mannose + 140 mg of proanthocyanidins (PAC), of prolonged release. / Amplio estudio (283 mujeres) sobre la eficacia de Manosar®: 2 g de d-manosa + 140 mg de proantocianidinas (PAC), de liberación prolongada frente a 240 mg de PAC de liberación prolongada en la prevención a 6 meses por vía oral de las infecciones urinarias recurrentes.

OBJECTIVE: To compare the efficacy and safety in the prophylasis of urinary tract infections (UTIs) with a food supplement that contains D-mannose like active ingredient (Manosar®), in comparison to another preparation in which the active ingredient are the proanthocyanidins (PAC), both of them, in prolonged released, after, they was administered for 24 weeks. METHODS: A multicenter, randomized and double blind experimental study was carried out. 283 women with a history of recurrent UTIs without evidence of complication were included. They were randomized 1: 1 in two groups. In one group, 1 oral sachet of Manosar® a day was administered, and in the other group 1 oral sachet of a compound of 240 mg of continuous-release PAC. Prior to inclusion in the study, the episode of UTI was confirmed at least by the clinical symptoms and positivity of the Combur test. RESULTS: Valid data were obtained from 184 patients with an average age of 49.5 years: 90 received Manosar® and 94 isolated PAC. A total of 72 patients suffered an UTI due to E.coli: 25 patients in the arm with Manosar® versus 47 patients in the isolated PAC group, this difference being statistically significant (p=0.002). The free time of new UTI recurrences was 98.6 days in the group treated with Manosar® and 84.6 days in the group with isolated PAC. CONCLUSION: The oral taking of a daily sachet of Manosar® is effective and safe in preventing recurrent UTIs in women, being superior to the oral taking of isolated PAC.

OBJETIVO: Comparar la eficacia y seguridad de la profilaxis de las infecciones del tracto urinario (ITUs) con un complemento alimenticio que contiene D-manosa como principio activo principal (Manosar®), en comparación con otro preparado cuyo principio activo único son las proantocianidinas (PAC), ambos de liberación continuada, tras su administración durante24 semanas.MÉTODOS: Estudio experimental multicéntrico, aleatorizado y doble ciego. Se incluyeron 283 mujeres con historia de ITUs recurrentes sin evidencias de complicación. Se randomizaron 1:1 en dos grupos. En un grupo se administró 1 sobre diario oral de Manosar®, y en el otro 1 sobre diario oral de un compuesto de 240 mg de PAC de liberación continuada. Previo a la inclusión en el estudio se confirmó el episodio de ITU al menos por la sintomatología clínica y positividad del test de Combur. RESULTADOS: Se obtuvieron datos válidos de 184 pacientes con edad media de 49,5 años: 90 recibieron Manosar® y 94 PAC aislado. Un total de 72 pacientes padecieron una ITU por E.coli: 25 pacientes en el brazo con Manosar® frente a 47 pacientes en el grupo de PAC aislado, siendo esta diferencia estadísticamente significativa (p=0,002). El tiempo libre de nuevas recurrencias de ITU fue de 98,6 días en el grupo tratado con Manosar® y de 84,6 días en el grupo con PAC aislado.CONCLUSIÓN: La toma oral de un sobre al día de Manosar® es eficaz y segura en la prevención de las ITUs recurrentes en la mujer, siendo superior a la toma oral de PAC aislado.

[Ureteral triplication whitout other associates malformations]. / Triplicidad ureteral sin otras malformaciones asociadas.

We report a case of ureteral type III triplication according to Smith's classification, without associated anomalies of the urinary tract. The revision of the bibliography indicates the rarity of this maldformacion and its frequent association with other urinary and extraurinary malformations. The absence of associate malformations in this case increases his exceptionality.

[Urodynamic evaluation in prostate cancer patients with urinary incontinence]. / Valoración urodinámica en el cáncer de próstata con incontinencia.

OBJECTIVES: Update on the urodynamic evaluation in patients with prostate cancer who have incontinence. METHODS: To review the urodynamic studies in prostate cancer patients who suffer from incontinence, irrespective of the treatment carried out. RESULTS: The largest amount of information on urodynamic studies in patients with prostate cancer and incontinence was found in those with post-prostatectomy incontinence. There is much more limited work on irradiated patients, and after medical treatment. CONCLUSION: The urodynamic study in these patients may help clarify the etiopathogenic mechanisms of incontinence, try to predict risk factors before treatment and help the therapeutic decision making. Further studies are needed, especially in patients undergoing radiotherapy, to further assess the mechanisms involved in lower urinary tract abnormalities that occur in these patients.

[Functional changes during the voiding phase in males with non-neurogenic detrusor underactivity undergoing bladder catheterization.] / Cambios funcionales en la fase miccional de varones diagnosticados de detrusor hipoactivo no neurogénico sometidos a cateterización vesical.

OBJECTIVES: To investigate urodynamic changes during the voiding phase in males with detrusor underactivity (DU) undergoing bladder catheterization for urinary retention. METHODS: From a total of 64 patients with urinary retention, a follow-up study was performed in 17 males with a mean age of 77 years. Patients received a urodynamic diagnosis of DU based on a Bladder Contractility Index (BCI) score of < 100 and underwent permanent bladder catheterization (16 cases) or clean intermittent catheterization (1 case) for acute urinary retention (14 cases), or post void residual urine (3 cases). Patients underwent a second urodynamic study after a mean 13 months of follow-up. Fisher's exact test was used with categorical variables and Student's t test with parametric variables. The level of significance was set at p < 0.05 for a two-sided test. RESULTS: The second urodynamic study showed a significant increase in maximal detrusor pressure, pressure at maximum flow rate, BCI score, Bladder Outlet Obstruction Index (BOOI) score, and number of patients who urinated during the pressure-flow study. CONCLUSIONS: Bladder catheterization in men with DU significantly improves bladder contractility and revealed obstructions of the lower urinary tract that were masked by insufficient detrusor pressure in relation to the DU of these patients. These findings could have diagnostic as well as prognostic and therapeutic applications.

OBJETIVOS: Determinar los cambios urodinámicos de la fase miccional en varones con hipocontractilidad del detrusor (DU) sometidos a cateterismo vesical por retención urinaria. MÉTODOS: De un total de 64 pacientes con retención urinaria, se realizó un estudio de seguimiento en 17 varones de edad media 77 años, diagnosticados urodinámicamente de DU por presentar un Índice de Contractilidad Vesical (BCI) menor de 100, sometidos a sonda vesical a permanencia (16 casos) o cateterismo vesical limpio intermitente (1 caso) por retención aguda de orina (14 casos), o residuo postmiccional patológico (3 casos). Los pacientes fueron sometidos a un segundo estudio urodinámico a los 13 meses de seguimiento de media. Las pruebas estadísticas utilizadas fueron el test exacto de Fisher para variables cualitativas y el test de comparación de media de la t de Student para variables paramétricas. El nivel de significación se fijó en p < 0,05 bilateral. RESULTADOS: En el segundo estudio urodinámico, se observó un aumento significativo de la presión máxima del detrusor, la presión a flujo máximo, el BCI y el Índice de Obstrucción de Salida Vesical (BOOI) y del número de pacientes que orinaron durante el estudio presión/ flujo. CONCLUSIONES: El cateterismo vesical en varones con DU mejora significativamente la contractilidad vesical y permiten desenmascarar obstrucciones del tracto urinario inferior que estaban ocultas por una insuficiente presión del detrusor en relación a la DU de estos pacientes. Esto podría tener no sólo aplicaciones diagnósticas, sino pronósticas y terapéuticas.
