Objectives: To determine the type of bladder outlet obstruction (BOO) in patients with Parkinson's disease (PD)., Material and Method: A case-control study was carried out in 46 patients divided into two groups. Group 1 formed by 23 PD patients with BOO (a URA parameter ≥ 29 cm H 2 O). Group 2 formed by 23 patients with benign prostatic hyperplasia (BPH) and compressive obstruction (an opening pressure > 35 cm H 2 O) and URA parameter ≥ 29 cm H 2 O). Both groups underwent a pressure-flow study to calculate Dynamic Urethral Resistance Relationship (DURR) patterns. Based on previous research, we describe two types of DURR pattern. Pattern A typical of dynamic or functional obstruction and pattern B typical of static or organic obstruction., Results: We found that PD patients had a significantly higher frequency of pattern A (70%) than BPH patients (4%). Other significant differences between groups were age (greater in PD group), bladder compliance (greater in PD group), maximum flow rate [Q max (greater in BPH group)], maximum detrusor pressure [P max (greater in BPH group)], detrusor pressure at maximum flow rate [PQ max (greater in BPH group)], opening detrusor pressure (greater in BPH group), and the bladder contractility parameters BCI and W max (greater in BPH group). There were no significant differences in perineal voiding electromyography (EMG) activity between groups nor relationship between voiding EMG activity and the type of DURR pattern., Conclusions: Our results are consistent with the usefulness of the DURR pattern to differentiate between functional and organic BOO in PD patients. Most PD patients have functional obstruction although a minority has organic obstruction consistent with BPH., (© 2024 Wiley Periodicals LLC.)

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.

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.

Objectives: To determine the risk factors of recurrent urinary infections (rUTIs) in patients with Multiple Sclerosis (MS)., Methods: A retrospective cohort study was conducted including 114 patients with MS, 84 women (74%) and 30 men (26%), with a mean age of 49. They underwent videourodynamic study and selective sphincter electromyography due to urinary symptoms (LUTS). Clinical data (both neurological and urological) and videourodynamic data (including free flowmetry, cystomanometry and pressure flow study) were collected. In 37 patients (32%), the presence of rTUIs was demonstrated., Results: Statistically significant differences were demonstrated between the patients with and without rUTIs with respect to the following clinical variables: the time of evolution of the symptoms (greater in the case of rUTIs), time from the diagnosis of MS (higher in the case of rUTIs), EDSS score (Expanded Disability Staus Scale) (higher in the case of rUTIs) and the EM type [higher frequency of rUTIs in the progressive types (primary and secondary)]. Urodynamic variables with significant differences were: maximum flow in free flowmetry (lower in patients with rUTIs), voiding volume in free flowmetry (lower in patients with rUTIs), micturition efficiency (higher percentage of residual urine in patients with rUTIs), stress urinary incontinence (SUI) (higher frequency of rUTIs in patients with SUI), detrusor pressure at maximum flow (lower in patients with rUTIs) and bladder contractility index (lower in patients with rUTI). No significant difference was demonstrated in relation to the presence and type of neurogenic lower urinary tract dysfunction (NLUTD)., Conclusions: The severity and duration of MS is a risk factor for rUTIs. Urodynamic risk factors are compatible with a lower contractile capacity in patients with rUTIs, while the existence of NLUTD would not imply any specific risk factor.

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.

Objective: To compare the efficacy and safety of dietary supplement "Manosar®" composed of D-mannose (2 g), 24 h prolonged release, associated with Proanthocyanidin (PAC) (140 mg), ursolic acid (7.98 mg), A, C, and D vitamins and the oligoelement zinc, versus 240 mg of PAC in recurrent urinary tract infections (UTI), for a designed follow-up of 24 weeks, in women., Methods: A multicenter randomized experimental double-blind study was carried out. The study was approved by review board of "Complejo Hospitalario de Toledo" (Spain), and all patients gave informed consent. A total of 150 women with non complicated UTI were screened for participation. Valid data was obtained from 93, with mean age of 48 years. Fortyfour patients were assigned to the Manosar® group and 51 patients to the PAC group. Patients were followed during six months. A previous UTI was defined based on a combination of symptoms and a positive reactive urine trip. Confirmation of a new UTI was based on symptoms, reactive urine strip and urine culture., Results: Thirty-three patients (35%) had an UTI during the six months follow-up. The percentage of UTI of the Manosar® group during this period was 24%, while the percentage of the PAC group was 45% (p〈0.05). The disease-free time for the Manosar® group was 95 days, while this time was 79 days for the PAC group. The incidence of side effects was low. Diarrhea was the most frequent side-effect in both groups., Conclusion: Manosar® (oral once a day) is more effective than single dose PAC (240 mg daily orally) to prevent recurrent UTI in women.

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., (© 2016 S. Karger AG, Basel.)

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 H 2 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.

Objective: To identify the prognostic factors influencing the clinical and urodynamics results on symptomatic benign prostatic hypertrophy (BHP) treatment in a series of patients with silodosin therapy from the URAL study., Methods: A retrospective study was performed in a cohort of 318 patients with BPH which underwent silodosine treatment, during at least 12 weeks., Results: Univariate analysis demonstrated that the variables in relationship with a decrease of urinary symptoms` punctuation postreatment (measured with the IPSS Questionnaire), a maximum peak flow (Q max) postreatment equal or superior to 15 ml/s, a postreatment postvoid residual lower to 100 ml, and a postreatment obstruction index ( Bladder Outlet Obstruction Index: BOOI) equal or lower to 20 cm H2O, presented such both as a clinical and urodynamic character. The multivariate analysis demonstrated that a decreased punctuation of IPSS Questionnaire postreatment was in relationship to: a pretreatment cystometry bladder capacity (direct relationship), pretreatment Qmax (direct relationship), pretreatment postvoid residual (inverse relationship), and pretreatment BOOI (inverse relationship)., Conclusion: The urodynamic study was very useful in the assessment of the prognostic factors in these patients.

Objective: The urodynamic results in suburethral slings (SS), are contradictory. We evaluate a series on patients with stress urinary incontinence (associated or not with bladder hyperactivity) that underwent suburethral slings (SS) operations., Methods: 42 women (age 62±12 years) with urinary incontinence underwent suburethral slings (86% TOT, 12% TVT, 2% others), 36% of them with simultaneous pelvic organ prolapse correction. Medical history and a pre and postsurgery urodynamic studies (according to ICS instructions, except when specified) were performed., Results: After surgery, the improvement of urinary incontinence was lower in patients with previous detrusor hyperactivity (DH) than without DH (60% vs 81 %), and the bladder capacity (BC) was lower (123±36 ml) in patients with previous mixed urinary incontinence (MUI) versus no MUI (241±83 ml) (p=0.004). The decrease of BC was higher with previous MUI (184±92 ml vs 123±36 ml) versus no MUI (240±91 ml vs 237±78 ml), and the DH was more frequent in previous MUI and DH. There was a significant decrease of maximum flow rate (Qmax) (p=0.000) (although without clinical manifestation), and post void residual urine (p=0.007). We demonstrated a significant increase (p=0.001) of mean urethral resistance (URA): 12±9 cm H2O versus 15±12 cm H2O (without reaching obstruction range), and an improvement of detrusor contractility (W80-20): (3±4 W/m2; vs 6±17 W/m2;)., Conclusion: We demonstrated worst results in MUI in patients with urinary incontinence undergoing SS. The urodynamic study gives a better prognosis reliability in the treatment of female urinary incontinence with SS.

Objective: To describe and quantify the long-term adverse effects on filling phase of lower urinary tract function in males submitted to radiotherapy., Methods: We performed a retrospective comparative study on a cohort of 99 men undergoing EBRT a mean of 4.7 years before for clinically localized prostate, rectum or colon neoplasia, and another cohort formed by 97 men over 50 years who did not undergo radiotherapy., Results: Cystometric bladder capacity and bladder capacity at first voiding desire were significantly lower in the radiotherapy group. Univariate analysis showed that the radiotherapy group evinced a risk to present a diminished compliance of 3.5 times more and 9.3 times more to find stress urinary incontinence, but we did not found increased risk for detrusor overactivity. In multivariate analysis the history of radical surgery acted as a confounding factor in the risk of stress urinary incontinence, but not to suffer diminished bladder compliance., Conclusions: The main long-term adverse effect of pelvic radiotherapy on male bladder function during filling is the increased risk of low bladder compliance.
