We also presented the result of 1-year follow-up aimed to illustrate its functional trifecta outcomes.<br /><strong>Methods</strong>: Robotic radical cystectomy with intracorporeal studer’s orthotopic neobladder was performed on 33 male patients by the same surgeon from April 2018 to March 2019. Nerve-sparing technique had been used in 11 of the 33 patients. A prospectively maintained dataset was retrospectively searched and the related perioperative and follow-up data were analyzed. The functional trifecta outcomes referred to the freedom from recurrence, urinary continence and sexual function recovery after one year.<br /><strong>Results</strong>: A total of 33 males were included in our study. All perioperative information was recorded in detail. Thirty-two cases were confirmed to have negative surgical margin, except one pT3a case. And another case of incidental prostate cancer was diagnosed pathologically. All patients (100%) were recurrence-free one year after the operation. Eleven patients underwent nerve-sparing surgeries, including inter-fascial techniques or intra-fascial techniques. All these patients attained daytime continence (0 pad) at 1 month. With the nighttime continence, nerve-sparing group (2, 2 ,1) used fewer pads than other 22 cases (3, 3 ,2) at 1, 6 or 12 month(s) respectively. We defined urinary continence as 0 pad in daytime and no more than 1 pad in nighttime. The median preoperative score of International Index of Erectile Function (IIEF-6) in the 11 cases was 24. The sexual function recovery was defined as IIEF-6 &gt; 20. The final trifecta rate was 54.5% and the median follow-up time lasted 17 months (range, 12 to 22 months). <br /><strong>Conclusions</strong>: RISON could be a safe and feasible choice of urinary diversion. Nerve sparing techniques might help the patients achieve a relatively higher functional trifecta rate.</p> 2022-11-09T00:00:00+00:00 Copyright (c) 2022 Hongzhao Li https://www.polscientific.com/bladder/index.php/bladder/article/view/844 Safety and Effectiveness of Nustim System Implantation in Dogs 2022-04-20T01:32:34+00:00 Xing Li lxcpums@126.com Han Deng lxcpums@126.com Zhaoxia Wang lxcpums@126.com Hao Li lxcpums@126.com Limin Liao lmliao@263.net <p class="a"><strong>Objectives:</strong> To verify the safety and effectiveness of a novel micro-implantable wireless nerve stimulation device in healthy adult beagles and evaluate the feasibility of using the device in clinical practice.</p> <p class="a"><strong>Methods:</strong> The stimulator was experimentally implanted into the quadriceps femoris of three adult beagles. The animals were subjected to training on daily basis for 14 days, and the threshold test was administered once a week. At the end, we analyzed the images of light microscopy and electron microscopy.</p> <p class="a"><strong>Results:</strong> The implantation was easy to perform and the whole stimulation system worked stably and reliably. The stimulation threshold was stable. During the process, the stimulator did not move or cause damage to adjacent tissues. The whole system showed a good biocompatibility with recipient animals. The stimulator could induce muscular contraction and enhance the motor function of muscles.</p> <p class="a"><strong>Conclusions:</strong> The preliminary results showed that the stimulator could be safely implanted into animal body, with good tissue compatibility, stability and reliability. In addition, it also worked well in eliciting muscle contraction. It promises to be used for the treatment of stress urinary incontinence in future.</p> 2022-09-14T00:00:00+00:00 Copyright (c) 2022 Xing Li, Han Deng, Zhaoxia Wang, Hao Li, Limin Liao https://www.polscientific.com/bladder/index.php/bladder/article/view/845 Treatment of stress urinary incontinence with a percutaneously implantable wireless microstimulator device (NuStim®) plus pelvic floor muscle exercises: a pilot study 2022-04-20T01:55:38+00:00 Fan Zhang zhangfan0207@126.com Limin Liao lmliao@263.net <p><strong>Objectives:</strong> To evaluate the utility and safety of pelvic floor muscle exercises in combination with a wireless percutaneously implantable microstimulator device (NuStim®) for the treatment of stress urinary incontinence.<br /><strong>Methods:</strong> In this prospective self-controlled pilot trial, three patients aged 35‒75 years with incontinence symptoms were treated by pelvic floor muscle exercises plus implantation of NuStim® from June 2017 to March 2019. The patients received 25 weeks of pelvic floor training, during which the patients’ incontinence was quantitatively assessed by a 1-h pad test. Self-reported scores were used to rate the effect of treatment in terms of the quality of daily life, with pelvic floor muscle strength evaluated on the modified Oxford scale at each follow-up visit.<br /><strong>Results:</strong> All three patients (2 males and 1 female) completed the trial without dropouts. The results showed that their incontinence symptoms were alleviated, as measured by a decrease in the normalized weight of the 1-h pad test, which presented a significant linear trend (<em>P</em> = 0.0021). An intragroup analysis revealed that all participants achieved statistically significant improvement in terms of the 1-h pad test score at 25 weeks as compared with pre-training findings. Nonetheless, no significant difference was found between the results of the other follow-up points and the baseline before treatment (<em>P</em> = 0.058). Comparison of the secondary outcome variable scores in each participant showed no significant difference at the conclusion of the study.<br /><strong>Conclusions:</strong> Use of the NuStim® during pelvic floor muscle exercises resulted in significant improvement in incontinence symptoms. The device was shown to be useful and safe as an adjunct to the pelvic floor training for the treatment of stress urinary incontinence.</p> 2022-09-14T00:00:00+00:00 Copyright (c) 2022 Fan Zhang, Limin Liao https://www.polscientific.com/bladder/index.php/bladder/article/view/847 Chinese botulinum toxin A for the treatment of lower urinary tract dysfunction: It works just as well 2022-04-21T19:37:31+00:00 Fan Zhang zhangfan0207@126.com Qinggang Liu lqg1120@163.com Limin Liao lmliao@263.net Xiaojuan Li lixiaojuan309@sina.com Xueping Zhang zhangxp_lz@163.com <p>The botulinum neurotoxin type A (BoNT/A) is a neurotoxin produced by <em>Clostridium botulinum</em>. It causes botulism and represents the most powerful natural poison. In urological practice, the indications for BoNT/A therapy include neurogenic detrusor overactivity (NDO), idiopathic overactive bladder (OAB) or idiopathic detrusor overactivity (IDO), detrusor-sphincter dyssynergia (DSD), interstitial cystitis/bladder pain syndrome (IC/BPS), urinary tract infections (UTI), benign prostatic hyperplasia (BPH), and, more recently, chronic prostatic pain (CPP). BoNT/A is not only conducive to the treatment of muscle spasticity but also effectively works on hyperalgesia associated with various disorders of the lower urinary tract, thanks to its anti-nociceptive properties. While Botox® (Allergan Inc., Irvine, CA) is currently being used across the globe, we have been using Chinese BoNT/A for many years for the treatment of DSD, NDO, idiopathic OAB, IC/BPS, BPH and UTI. Our experience showed that Chinese BoNT/A was as good as other BoNT/A products in terms of efficacy, safety, and tolerability. In this study, we explored the current and potential applications of Chinese BoNT/A in urology, and reviewed the background information regarding the toxin.</p> 2022-09-14T00:00:00+00:00 Copyright (c) 2022 Fan Zhang, Qinggang Liu, Limin Liao, Xiaojuan Li, Xueping Zhang
