Is bladder outlet obstruction responsible for a successful surgical outcome in women with complicated stress urinary incontinence? Urodynamic results before and after a Remeex® readjustable sling.

AIMS: To describe the changes in urodynamic parameters after Remeex® placement in women with recurrent stress urinary incontinence (rSUI) or intrinsic sphincteric deficiency (ISD) and to analyze a potential relationship between postoperative bladder outlet obstruction and a successful surgical outcome. METHODS: Retrospective analysis of those women who had undergone Remeex® placement due to rSUI or ISD in our department between 2000 and 2017. All patients underwent urodynamic evaluation before and after the surgery. If tension readjustment was required, postoperative urodynamics was performed after the last regulation, once the final continence status had been achieved. The female Bladder Outlet Obstruction Index (BOOIf) was calculated for all patients postoperatively. Obstruction was considered present if BOOIf was >18. Pre- and postoperative urodynamic variables were compared. Postoperative urodynamic changes were also compared between cured and noncured patients. RESULTS: A total of 205 women were included. After a follow-up of 89 ± 36 months, 165 women (80.5%) were continent. A significant impairment in the majority of the urodynamic parameters was observed. Mean postoperative BOOIf was -11.8 ± 21.5 in cured patients and -15.3 ± 23.1 in noncured patients (p = 0.365); 15 (9.1%) patients in the cured group had a postoperative BOOIf >18, whereas all (100%) patients in the noncured group had a postoperative BOOIf <18. CONCLUSIONS: Most urodynamic parameters may worsen after the Remeex® system placement. Postoperative urodynamic parameters may not differ substantially between cured and noncured patients, although a certain grade of bladder outlet obstruction could be related to postoperative continence status in some patients.

Treatment Response and Complications after Intradetrusor OnabotulinumtoxinA Injection in Male Patients with Idiopathic Overactive Bladder Syndrome.

PURPOSE: We sought to assess the treatment response, complications and treatment continuation after onabotulinumtoxinA injection in male patients. MATERIALS AND METHODS: We performed a retrospective study of men with refractory idiopathic overactive bladder treated with intradetrusor injection of 100 IU onabotulinumtoxinA since 2007 in our department. Patients with previous radical prostatectomy were excluded from analysis. The treatment response was assessed using a treatment benefit scale of 1-greatly improved, 2-improved, 3-not changed and 4-worse after treatment. A treatment benefit scale score of 1 or 2 was considered a treatment response. Complications were classified according to the CD (Clavien-Dindo) classification. Treatment was considered to have continued if at the last visit patients had received an onabotulinumtoxinA injection within the preceding 12 months. We performed univariate and multivariate analyses to assess factors predictive of the treatment response, complications and continuation on treatment. RESULTS: Of the 146 men with a mean ± SD age of 70.1 ± 13.3 years who were included in study 91 (62.3%) reported a response to treatment. A total of 24 complications (16.4%) were detected, including 19 cases (13%) of urinary retention (CD 2), 2 (1.3%) of hematuria (CD 1) and 3 (2%) of urinary infection (CD 2). Followup was more than 12 months in 128 patients, of whom 88 (68.8%) had discontinued treatment by the end of followup. A higher bladder outlet obstruction index was the only factor predicting a lower treatment response rate and a higher complication rate. CONCLUSIONS: Most male patients with idiopathic overactive bladder showed a treatment response after intradetrusor onabotulinumtoxinA injection. However, the majority discontinued treatment. A higher bladder outlet obstruction index was related to a lower treatment response and a higher complication rate.

The relationship between calcium oxalate lithiasis and chronic proinflammatory intestinal dysbiosis pattern: a prospective study.

The objective is to establish whether a pattern of intestinal dysbiosis exists in calcium oxalate (CaOx) lithiasis and, if so, to identify its characteristics and explore whether there are differences in the pattern between CaOx dihydrate (COD) and monohydrate (COM) lithiasis. With this aim 24 patients diagnosed with CaOx lithiasis by means of optical microscopy and spectrometry were prospectively recruited. Faecal analysis was carried out by means of RT-PCR 16S rRNA assay and agar plate culture according to the methodology proposed by the Institute of Microecology (Herborn, Germany). The total number of bacteria was depleted due to COD lithiasis (p = 0.036). The mean values of immunoregulating microbiota were normal, but the percentage of normal values was lower in the COD group (30%) than in the COM group (69.2%) (p = 0.062). The total mean values of protective microbiota were normal in both groups. There was a large decrease in the mean values of the muconutritive microbiota Akkermansia muciniphila and Faecalibacterium prausnitzii, the most intense decline being observed in the COD group (p = 0.019). Levels of proteolytic microbiota were elevated in both groups, without differences between them. We conclude that patients with CaOx lithiasis have a chronic pro-inflammatory intestinal dysbiosis pattern characterised by a reduction in the total number of bacteria, a reduction in immunoregulating microbiota and a large reduction in muconutritive microbiota that is significantly more intense in COD lithiasis than in COM lithiasis.
