Objectives To report the long-term efficacy and complications of the augmentation uretero-enterocystoplasty (AUEC), including augmentation cystoplasty with simultaneous ureteroplasty and ureteral anti-reflux implantation in a single center. Methods We retrospectively reviewed clinical records, video-urodynamic data, and magnetic resonance urography of 210 patients who underwent the procedure for refractory lower urinary tract dysfunction (LUTD) from 2003 to 2019. International vesicoureteral reflux (VUR) and upper urinary tract dilatation (UUTD) grading systems were applied to assess upper urinary tract function, and post-operative complications were assessed. Results Mean age was 28.1 years, with a mean follow-up time of 57.4 months. A total of 338 ureters were simultaneously re-implanted, and ureteroplasty was performed on all ureters. There was a significant postoperative improvement in the bladder capacity, intravesical pressure, and compliance (P < 0.05). VUR improvement rate was 97.7% and postoperative improvement of UUTD presented in 72.5% ureters. Mean serum creatinine (Scr) level was significantly improved compared to preoperative Scr values (226.0 ± 89.4 μmol/L vs. 217.5 ± 133.9 umol/L, P < 0.05). The 1.0% patients had unacceptably postoperative urinary incontinence and 85.4% preoperative megaureters were improved. Primary complications included metabolic acidosis (9.5%), vesicoureteral anastomosis stenosis (6.2%), persistent VUR (2.7%), urinary calculi (6.6%), and intestinal dysfunction requiring laparotomy (3.3%). Conclusion In the study, a large series of patients treated with a complex surgical procedure was reported. It is novel, as this case series represents patients with aggressive surgical correction of VUR, ureteral tortuosity and upper tract dilation at the time of AC. AUEC was shown to have a positive role in treating patients with refractory LUTD associated with hydronephrosis and ureteral dilatation, stenosis or obstruction, with or without high- or low-pressure VUR. It was effective in improving renal function and protecting the UUT function from further deterioration in most patients with renal insufficiency.

Aims To assess the urodynamic findings during the filling phase in neurogenic bladder patients with or without vesicoureteral reflux (VUR) who underwent sacral neuromodulation (SNM). Methods We retrospectively reviewed the records of 19 patients with neurogenic lower urinary tract dysfunction (NLUTD) who underwent SNM at our center from July 2018 to July 2019. Clinical data and video‐urodynamic parameters were collected. VUR grading systems were used to evaluate upper urinary tract function. Results The mean test duration was 24 ± 8.2 days. The urodynamic evaluation showed a significant increase in the mean maximum cystometric capacity (136.3 ± 118.2 vs 216.5 ± 137.8 mL; P = .0071) and compliance (8.7 ± 8.52 vs18.3 + 16.47 mL/H2O; P = .016), as well as a decrease in maximum intravesical pressure (57 ± 39.23 vs 36.58 ± 31.16 H2O; P = .0064). In the voiding phase, none of the patients had automatic urination at the baseline and testing phases. In 8 of 19 patients who had detrusor overactivity (DO), the DO disappeared (four patients) or was delayed (four patients). The VUR in 3 of 12 ureter units disappeared. The grade of VUR or the volume before VUR improved in 8 ureter units, and the remaining 1 did not change significantly. An implant was performed in 16 cases. After permanent implantation, all patients needed intermittent catheterization to empty the bladder. Conclusions This retrospective study indicates that SNM can improve the urinary storage function of the bladder in appropriate patients with NLUTD. For patients with VUR, SNM can cure or reduce VUR by improving DO and bladder compliance.

Purpose This resting‐state functional magnetic resonance imaging (fMRI) study determined the functional connectivity (FC) changes and topologic property alterations of the brain functional network provoked by a strong desire to void in healthy adults using a graph theory analysis (GTA). Materials and methods Thirty‐four healthy, right‐handed subjects filled their bladders by drinking water. The subjects were scanned under an empty bladder and a strong desire to void states. The Pearson's correlation coefficients were calculated among 90 brain regions in the automated anatomical labeling (AAL) atlas to construct the brain functional network. A paired t test (P < .05, after false discovery rate [FDR] correction) was used to detect significant differences in the FC, topologic properties (small‐world parameters [gamma, sigma], Cp, Lp, Eglob, Eloc, and Enodal) between the two states in all subjects. Results Both the two states showed small‐world network properties. The clustering coefficient (Cp) and local efficiency (Eloc) in the whole brain network decreased, while the FC within the default mode network (DMN) increased during the strong desire to void compared with the empty bladder state. Moreover, an increased nodal efficiency (Enodal) was detected in the basal ganglia (BG), DMN, sensorimotor‐related network (SMN), and visual network (VN). Conclusion We detected FC changes and topologic property alterations in brain functional networks caused by a strong desire to void in healthy and suggest that the micturition control may be a process dominated by DMN and coordinated by multiple sub‐networks (such as, BG, SMN, and VN), which could serve as a baseline for understanding the pathologic process underlying bladder dysfunction and be useful to improve targeted therapy in the future.
