Aim — The aim of this study was to analyse how conventional urodynamic values differ between females with specific types of urinary incontinence (UI). Material and Methods — Cross-sectional study enrolled 666 females with UI. Based on patient history and questionnaires they were divided into three groups: stress (SUI), mixed (MixUI) and urgency (UUI). Physical investigation and urodynamics were performed. The continuous factors: age and urodynamic data were evaluated using Multinomial regression and ANOVA test using SUI, MixUI, UUI as outcome groups. Results — Analysing urodynamic parameters significant difference between at least two groups was shown by the cystometric capacity and maximum flow rate: both highest in the SUI group; residual urine, opening detrusor pressure, maximum urethral closure pressure at rest, functional urethral length at rest: all highest in the UUI group. Mainly all urodynamic data showed significant difference between SUI/UUI, and MixUI/UUI groups, while difference between SUI/MixUI were not significant. Conclusions — Most of urodynamic data for MixUI group patients do not differ from SUI group. UDS parameters like: maximum flow rate, residual urine, opening detrusor pressure, maximum urethral closure pressure at rest, functional urethral length at rest can help to distinguish SUI and MixUI groups from UUI group.

Objectives. To compare the outcome of dorsal buccal mucosal graft (BMG) substitution urethroplasty by dorsal urethrotomy approach with ventral urethrotomy approach in management of stricture urethra.Methods and Materials. A total of 40 patients who underwent dorsal BMG substitution urethroplasty were randomized into two groups. 20 patients underwent dorsal onlay BMG urethroplasty as described by Barbagli, and the other 20 patients underwent dorsal BMG urethroplasty by ventral urethrotomy as described by Asopa. Operative time, success rate, satisfaction rate, and complications were compared between the two groups. Mean follow-up was 12 months (6–24 months).Results. Ventral urethrotomy group had considerably lesser operative time although the difference was not statistically significant. Patients in dorsal group had mean maximum flow rate of 19.6 mL/min and mean residual urine of 27 mL, whereas ventral group had a mean maximum flow rate of 18.8 and residual urine of 32 mL. Eighteen out of twenty patients voided well in each group, and postoperative imaging study in these patients showed a good lumen with no evidence of leak or extravasation.Conclusion. Though ventral sagittal urethrotomy preserves the blood supply of urethra and intraoperative time was less than dorsal urethrotomy technique, there was no statistically significant difference in final outcome using either technique.

Objective: To investigate the safety and efficacy of the combination of suprapubic prostatectomy with transurethral resection of the prostate (TURP) for the treatment of large volume benign prostatic hyperplasia (BPH). Methods: We retrospectively analyzed the clinical data of two methods of treatment with 60 cases of a large volume BPH (>100 g) from January 2011 to 2017; the methods were suprapubic prostatectomy and suprapubic prostatectomy combination with TURP, in which the single open group comprised 30 cases, treated using the former method, and the combined open group comprised the other 30 cases, treated using the latter method. In the combined open group, the residual prostate gland was removed by TURP. We compared both the groups of patients using age, prostate volume, international prostate symptom score (IPSS), prostate-specific antigen (PSA), maximum flow rate, residual urine, operation time, hospitalization time, postoperative washing time, blood transfusion rate, and decreased amount of intraoperative hemoglobin in operation, and compared the preoperative and postoperative IPSS, maximum flow rate, and residual urine volume. Results: There was no significant difference between the two groups in age, prostate volume, IPSS, PSA, maximum flow rate, residual urine, and other clinical data ( P > 0.05); the single group operation time, postoperative bladder irrigation time, hospitalization time, blood transfusion rate, and decreased amount of intraoperative hemoglobin were significantly greater in the single open group than in the combined open group, and statistically significant differences were observed between both the groups ( P < 0.05). Postoperative voiding function improved significantly compared with the preoperative, and a statistically significant difference was observed ( P < 0.05). Conclusion: The combination of suprapubic prostatectomy with TURP is an effective and a safe surgical method for the treatment of patients with large volume BPH. It is certainly worthy of clinical application.

Abstract Background The management of short anterior urethral stricture is challenging. Our study aims to evaluate the outcome of augmented anastomotic urethroplasty (AAU) for the management of men with ultra-short penile urethral stricture, and to compare it with the dorsal onlay buccal mucosa graft. Methods Databases of two tertiary referral centres were retrospectively reviewed to retrieve data of men with ultra-short penile urethral stricture who underwent urethroplasty from 2013 to 2020. Patients who underwent AAU with ventral onlay pedicled skin flap were considered the study group, while patients treated with the dorsal onlay graft augmentation were included as controls. Surgical outcomes included urethral patency, improvement in the maximum flow rate (Qmax), change in sexual satisfaction, and any reported complications. Results Thirty-four patients (and 30 controls) with a median age of 26–27 years were included in the study. The maximum flow rate improved significantly in both groups compared to the preoperative value (p < 0.001). The success rate was 88% in the study group compared to 76.7% in the control group. There was no statistically significant difference in the frequency of postoperative penile curvature nor the ventral sacculation between the two groups (p = 0.788 and 0.913). The operative time was statistically significantly longer in the control group (p = 0.044), while the frequency of postoperative void dripping was much higher in the study group (p = 0.007). Conclusion The success rate and complications of AAU for men with ultra-short penile urethral stricture were comparable to the dorsal buccal graft.

Objective: Overactive bladder (OAB) is a disease characterized by the presence of urinary urgency. We carried out a meta-analysis to assess the effectiveness and safety of trigonal-involved injection of onabotulinumtoxinA (BoNT-A) in comparison with the trigonal-sparing technique in cases with OAB [neurogenic detrusor overactivity (NDO) and idiopathic detrusor overactivity (IDO)].Methods: Randomized controlled trials (RCTs) of BoNT-A injection for OAB were searched systematically by using EMBASE, MEDLINE, and the Cochrane Controlled Trials Register. The datum was calculated by RevMan version 5.3.0. The original references of relating articles were also reviewed.Results: In total, six RCTs involving 437 patients were included in our analysis. For OAB, the trigone-including group showed a different patient symptom score (p = 0.03), complete dryness rate (p = 0.002), frequency of incontinence episodes (p = 0.01), detrusor pressure at maximum flow rate (p = 0.01), and volume at the first desire to void (p = 0.0004) compared with the trigone-sparing group. Also, a trigone-including intradetrusor injection demonstrated a significant improvement in the patient symptom score (p = 0.0004), complete dryness rate (p = 0.0002), frequency of incontinence episodes (p = 0.0003), detrusor pressure at maximum flow rate (p = 0.01), and volume at the first desire to void (p = 0.00006) compared with the trigone-sparing group for treatment of NDO. The adverse events rates were similar in both groups.Conclusions: The meta-analysis has demonstrated that trigone-including BoNT-A injection was more effective compared with the trigone-sparing injection for the treatment of OAB, especially for NDO.

Abstract: The city of Volta Redonda, located in the state of Rio de Janeiro, has a controlled landfill of municipal solid waste (MSW) which was partially recovered in 2008. This disposal site has no data on the amount of waste volume landfilled. An Unmanned Aerial Vehicle (UAV) was used to capture images of the study area and through Geographic Information Systems (GIS) the biogas generation was determined. By overlaying the georeferenced images the contour lines were determined which enabled the creation of the 3D Digital Terrain Model (DTM) of the area with a resolution of 0.296349 m / pix. The DTM provided the determination of the volume of waste landfilled (535.755,79 m3) and the real surface area (36.770,96 m2) of the controlled landfill. These parameters allowed obtainment the maximum flow rate of methane generation of 16.539,82 m3 for 2007. The Brazilian model used to determination biogas generation in waste sector achieve a maximum flow rate of methane generation of 126.599,4 m3 for the year 2007. A significant difference between biogas generation in the two models was observed mainly due to the amount of waste determined in both models.

Uncertainty remains whether it is best for men to void in a sitting or standing position. The objective of this study is to evaluate the effect of standing and sitting voiding position on uroflowmetry parameters and post void residual urine (PVRU) in patients with lower urinary tract symptoms (LUTS) due to benign prostate hyperplasia (BPH) and healthy men. A total of 116 participants with BPH (Group 1) and 78 healthy men (Group 2) were enrolled in the study. The uroflowmetry parameters were measured in both positions. The PVRU volume was measured using transabdominal ultrasound after each voiding. Uroflowmetry parameters and PVRU were measured and compared between the two different voiding positions using Wilcoxon signed rank test. In Group 1, there were significant statistical differences in uroflowmetry parameters between standing and sitting voiding position. The median of maximum flow rate in Group 1 in standing and sitting position was 14.7 ml/s (IQR; 11.7–17.5) and 11 ml/s (IQR; 8.9–13.3), respectively ( p < .0001). The median voided volume at standing position was 340 ml (IQR; 276–455) while it was 267 ml (IQR; 194–390) at sitting position ( p < .0001). Median average flow rate in standing position was 5.9 ml/s (IQR; 4.5–7.5) and 5 ml (IQR; 3.2–6.4) in sitting position. There was a statistically significant difference between the median of PVRU in standing and sitting position ( p < .0001). In patients with BPH, voiding in standing position showed better uroflowmetry parameters and significant less PVRU volume.

The aim of the paper is to compare the pre-operative and postoperative urodynamic parameters of women with stress incontinence undergoing a TVT (Tension-free Vaginal Tape) operation in order to evaluate the functional dynamics of the operation. Twenty-two patients (mean age 56.3 years, range 30-69 years) underwent the TVT operation for the correction of stress urinary incontinence. Cervical urethral hypermobility was present in all the patients and only the TVT operation and no other surgical procedure was performed. The main urodynamic modification was the improved transmission pressure to the urethra (CTU%) at the post-operative check up, although the maximum urethral closure pressure (MUCP), the functional length (FL) and the maximum flow (Qmax) remained unchanged.

Background: Substitution urethroplasty using buccal mucosal grafts can be performed by several approaches including ventral onlay graft, dorsal onlay graft, or ventral urethrotomy with dorsal inlay graft. Our study aims to evaluate the surgical outcome of dorsolateral buccal mucosal graft for long segment anterior urethral stricture >6 cm in patients with Lichen sclerosus (LS). Methods: A retrospective study included patients who underwent repair for long segment anterior urethral stricture >6 cm due to LS between January 2013 and April 2019. All patients were followed-up at 3, 6, 9, and 12 months postoperatively and then yearly by clinical symptoms, uroflowmetry, and calculation of post-void residual urine volume. Retrograde urethrogram was requested for patients with voiding symptoms or decreased maximum flow rate. Stricture recurrence that required subsequent urethrotomy or urethroplasty was considered failure. The success rate and surgical complications were collected and analyzed. Results: Thirty patients were identified. The median age (range) was 39 (25–61) years and a median (range) stricture length was 8 (6–14) cm. Most of postoperative complications were of minor degree. The success rate at median follow-up of 15 (12–24) months was 86.5%. The median maximum flow rate increased significantly from 6 (2–11) ml/s preoperatively to 18 (range: 6–23) ml/s at the 6th month ( p value < 0.001). Conclusion: Dorsolateral buccal mucosal grafts urethroplasty for long anterior urethral stricture caused by LS has a high success rate and low risk of complications including stricture recurrence.

A theoretical model is developed for predicting the maximum flow rate of a single component, two-phase mixture. It is based upon annular flow, uniform linear velocities of each phase, and equilibrium between liquid and vapor. Flow rate is maximized with respect to local slip ratio and static pressure for known stagnation conditions. Graphs are presented giving maximum steam/water flow rates for: local static pressures between 25 and 3,000 psia, with local qualities from 0.01 to 1.00; local stagnation pressures and enthalpies which cover the range of saturation states.
