Objective To observe the mid-and long-term effects of Kegel training combined with Pilates training on urinary conti-nence recovery in different body mass index(BMI)male patients with urinary incontinence after prostatectomy.Methods From May,2023 to June,2024,48 patients in Beijing Bo'ai Hospital were recruited and divided into group A(<25 kg/m2,n=15),group B(25 to 30 kg/m2,n=18)and group C(>30 kg/m2,n=15)according to their BMI.All the groups performed Kegel training combined with Pilates training for two months,and followed up at six months from baseline.They were evaluated with one hour pad test,the number of daily urinary incontinence,In-ternational Consultation on Incontinence Questionnaire-Short Form(ICIQ-SF)and modified Oxford Rating Scale before treatment,and four weeks,eight weeks and six months after treatment.Results The intra-group effect,the inter-group effect and interaction effect were significant in the results of one hour pad test and the daily number of urinary incontinence(F>2.955,P<0.05).Post Hoc test showed that they were worse in group C than in groups A and B(P<0.05),and the number of daily urinary incontinence was more in group B than in group A(P<0.05).There was significant difference in the scores of ICIQ-SF and modified Ox-ford Rating Scale among groups in different time points after treatment(Z>10.476,P<0.05)except the score of ICIQ-SF four weeks after treatment(P>0.05),and they were the worst in group C.BMI(group A=1,group B=2,group C=3)was correlated with the results of one hour pad test(r=0.79,P<0.001),the number of daily uri-nary incontinence(r=0.68,P<0.001),and the scores of ICIQ-SF(r=0.68,P<0.001)and modified Oxford Rating Scale(r=-0.47,P=0.001)six months after treatment.Conclusion Kegel training combined with Pilates training could improve the urinary control in patients with urinary in-continence after prostatectomy.The decrease of BMI can promote the recovery of urinary control,and improve the symptoms of later urinary incontinence in mid-and long-term.

Urinary tract obstruction symptoms as the predominant manifestation of interstitial cystitis/bladder pain syndrome (IC/BPS) are uncommon and can easily be misdiagnosed as bladder neck obstruction, benign prostatic hyperplasia, or prostatitis. This article reports three cases of such patients. Case 1 was a 61-year-old male, case 2 was a 53-year-old female, and case 3 was a 26-year-old male. Cases 1 and 2 were initially suspected of having bladder neck obstruction, and both underwent bladder neck incision, which resulted in poor outcomes. Case 3 was initially diagnosed with chronic prostatitis. All three patients were diagnosed with IC/BPS after undergoing bladder hydrodistention therapy. One patient received intravesical botulinum toxin A injection following hydrodistention. After treatment, the patients were followed up for 4 months, 2.5 months, and 1.5 months, respectively, and all reported satisfactory symptom improvement.

Objective:To investigate the effect of biofeedback combined with pelvic floor training on stress urinary incontinence in elderly men.Methods:This study was prospective and Patients with urinary incontinence after radical prostatectomy from China Rehabilitation Research Center were enrolled. The patients who could not complete or refused the study, had a history of other urinary diseases, and central nervous system diseases were excluded. Patients were divided by random number table method into 3 groups. They were Kegel training group (Group A)which underwent anus contraction training with each contraction for 5 seconds and a rest interval of 2 seconds. Biofeedback combined with Kegel training group (Group B), which was biofeedback combined with anus contraction training and the biofeedback combined Pilates group (Group C) which received the biofeedback combined Pilates training. In group B and group C, patients were placed in the right lateral position and the surface electrode of the rectal probe was inserted into the anus. The reference electrode was fixed at the adductor muscle of the right thigh. The patient is asked to squeeze the electrode as hard as possible by constricting the anus so that the electromyographic signals produced by constricting the anus are synchronized with those on the computer screen. In the electrical stimulation stage of biofeedback therapy, rhomboid waves with current intensity of 30-50 Hz and pulse width of 300μs were used, and the electrical stimulation intensity was determined by the subtle muscle contraction visible. Each of the three training sessions lasted 45 minutes a day for 8 weeks. 1 hour pad test, daily incontinence times, (International Incontinence Counseling Questionnaire, ICIQ), and Oxford Score Scale were recorded every weekend. The 1-hour pad test, the number of incontinent episodes, ICIQ, Oxford Score scale before and after treatment were compared among the three groups, as well as the differences between the groups.Results:There were no significant differences in age, height, weight, history of diabetes or hypertension before treatment, time from postoperative to training, operation method, retention of nerve tract during surgery, Gleason score, 1-hour pad test, the number of episodes of incontinence, ICIQ and Oxford Grading Scale among the 3 groups. The 1-hour pad test results of group A, B and C were (37.4±7.2), (22.2±4.7) and (18.3±2.4) g, respectively, with statistical significance among the three groups ( P<0.01), and the difference between the three groups and before treatment was statistically significant ( P<0.01). The results of the number of episodes of incontinence in group A, B and C after treatment were (4.6±0.7), (3.4±0.6) and (3.0±0.8), respectively, and the difference among the three groups was statistically significant ( P<0.01), and the difference between the three groups and before treatment was statistically significant ( P<0.01). The results of The ICIQ in group A, B and C after treatment were 12(11, 14), 8(7, 9) and 6(5, 8), respectively, and the differences among the three groups were statistically significant ( P<0.01), and the differences between the three groups were statistically significant compared with before treatment ( P<0.01). The results of Oxford Grading Scale in group A, B and C after treatment were 3(3, 3), 4(3, 4) and 4(4, 4), respectively, and the difference between the three groups was statistically significant ( P<0.01), and the difference between the three groups was statistically significant compared with before treatment ( P<0.01). Conclusions:Biofeedback combined with pelvic floor training and biofeedback combined with Pilates training can improve urinary control, pelvic floor muscle strength, and stress urinary incontinence symptoms in male patients with stress urinary incontinence.

Objective To observe the clinical effect of Mirabegron combined with Silodosin on detrusor hyperactivity with impaired contractile (DHIC).Methods From September, 2019 to December, 2021, 40 patients with DHIC in the Department of Urology of Beijing Bo'ai Hospital were selected and randomly divided into control group and experimental group, with 20 cases in each group. The control group took Silodosin only, and the experimental group took Mirabegron in addition, for four weeks. The urinary diary, residual urine volume, Overactive Bladder Symptom Score (OABSS) and quality of life (QOL) score were compared before and after treatment.Results A total of 18 patients in the control group and 19 in the experimental group finished the trial. After treatment, the number of night urination per day, the residual urine volume and QOL score improved in the control group (P<0.01); the number of urination per 24 hours, the number of night urination per day, the volume per urination, the residual urine volume, the daily urgency score, the OABSS score and QOL score improved in the experimental group (P<0.01). The number decrease of urination per 24 hours, the volume decrease of per urination, the daily urgency score decrease, the OABSS score decrease and QOL score decrease were more in the experimental group than in the control group (P<0.01). The adverse reactions included palpitations, increased heart rate, dyspareunia, increased blood pressure, gastric discomfort, postural hypotension, and retrograde ejaculation, and there was no significant difference between two groups (P > 0.05).Conclusion The efficacy of Mirabellone combined with Silodosin on DHIC is better than Silodosin only, and there was no significant increase in drug-related adverse effects.

Objective:To investigate the long-term efficacy and complications of augmentation uretero-enterocystoplasty (AUEC).Methods:The clinical data of 262 patients with lower urinary tract dysfunction who underwent AUEC at our center from January 2003 to June 2022 were analyzed retrospectively. There were 193 males and 69 females, the median age was 24 (4, 67) years, the median disease duration was 12.0 (0.2, 56.0) years and the preoperative creatinine was 91.5 (68.1, 140.0) μmol/L. 320 ureters had high-grade UUTD, 216 ureters had VUR, 14 of which had low-pressure reflux.The number of low-grade VUR ureter was 22 (10.2%) and the number of high-grade VUR ureter was 194 (89.8%). Video-urodynamics showed that the maximum bladder capacity was 102 (47, 209) ml, the maximum detrusor pressure was 33.0 (15.5, 50.5) cmH 2O, and the bladder compliance was 6.4 (3.0, 12.3) ml/cmH 2O. All patients underwent AUEC. The surgical method is to cut a segment of sigmoid colon, open the sigmoid colon along the mesenteric margin, fold and suture it into " U" or " S" shaped intestinal mesh according to the principle of " detubulization" . At the same time, perform ureteroplasty and replanting, and then anastomosis the intestinal mesh with the opened bladder flap to form an expanded new bladder. Follow-up was performed via outpatient clinic or telephone. The creatinine, maximum bladder capacity, maximum detrusor pressure, bladder compliance, ureteral reflux and upper urinary tract dilatation were compared preoperatively and postoperatively. The postoperative complications were also evaluated. Results:The median follow-up time was 57.4 (4, 151) months after surgery. At 1-3 months after surgery, the maximum bladder capacity and bladder compliance increased to 303.9% and 189.9% of the preoperative level, and the maximum detrusor pressure decreased to 63.6% of the preoperative level. At 6-10 years after surgery, the maximum bladder capacity and bladder compliance increased to 490.2% and 627.9% and the maximum detrusor pressure decreased to 25.8% of the preoperative level. The UUTD of the patients was significantly reduced after surgery. The number of the high grade UUTD decreased to 116 (116/398, 29.2%) at 1-3 months and 51 (51/274, 18.6%) at 4-6 months. At 6-10 years, the number of the high-grade UUTD decreased to 4 (4/76, 5.3%) ( P<0.001), which was significantly lower than that before operation. The VUR was significantly relieved after operation, and 393 ureters had no VUR at 1-3 months, accounting for 97.8% (393/402) of the total ureters. Sustained remission of VUR was observed during follow-up. 73 ureters had no VUR at 6-10 years, accounting for 96.1% (73/76) of total ureters ( P<0.001). Patients' creatinine decreased to 79.0 (65.0-128.2) μmol/L at 1-3 months postoperatively, with a downward trend but no statistical difference, and creatinine levels were not significantly elevated at any postoperative time point compared with preoperative levels ( P>0.05). Postoperative complications included metabolic acidosis in 26 cases (9.9%), vesicoureteral anastomosis stenosis in 15 cases (5.7%), recurrent urinary tract infection in 16 cases (6.1%), and urinary calculi in 20 cases (7.6%), and intestinal obstruction requiring laparotomy in 8 cases (3.1%), all of them could be improved after treatments. Conclusions:AUEC is a safe and effective method for treating high-grade VUR or VUR with impaired anti-reflux mechanism, high-grade UUTD or UUTD with ureteral or vesicoureteral junction obstruction, and all of the complications can be improved after treatment. This technique can increase the bladder capacity and compliance, reconstruct the anti-reflux mechanism, and release upper urinary tract obstruction. It may play an important role in stabilizing and protecting the residual renal function from further deterioration.

Objective:To investigate the long term outcome of artificial urinary sphincter implantation for patients with stress urinary incontinence.Methods:The data of 46 patients who underwent artificial urethral sphincter implantation in China Rehabilitation Research Center from April 2002 to April 2022 were retrospectively analyzed.The patients’ age ranged from 19-80 years old (median 45.6 years). There were 45 males and 1 female. The history of illness was 8 months to 33 years. The patients category were urethral injuries associated urinary incontinence ( n=24), neurogenic urinary incontinence ( n=9) and post-prostatectomy incontinence ( n=13). Preoperative daily pad usage was 3.5±1.0. The impact of incontinence on the quality of life (QOL)measured by the visual analogue scale (VAS)was 7.1±1.2. All 46 patients underwent artificial urethral sphincter implantation, of which 20 patients were treated with anticholinergic drugs (5 cases) or urinary tract related surgery (urethral stenosis incision in 2 cases, sphincterectomy in 3 cases, urethral dilation in 5 cases, urethral calculus lithotripsy in 1 case, and augmentation cystoplasty in 4 cases) before artificial urethral sphincter implantation. Of the 45 male patients, 25 patients had the transperineal approach and 20 had the trans-scrotal approach. The female case had a trans-retropubic approach. Different cuffs size was used based on individual circumference of bulbar urethra (45 male cases: 4.5cm in 16 cases, 4.0cm in 29 cases; one female case: 8.0cm). Long-term surgical efficacy was evaluated. Assessments included postoperative urinary continence (socially continent: one pad per day or less; complete dry: wearing no pads), artificial urinary sphincter status and complications. The influences of patients of different etiologies, surgical approaches and cuff size on surgical results were compared. Results:The mean follow-up time was 7.1 years ranged from 6 months to 19 years. At the latest visit, 32 patients (69.6%) maintained the primary functional artificial urinary sphincter. Three patients (6.5%) had artificial urinary sphincter revisions and maintained continence with the new device. 11 patients (23.9%) removed the artificial urinary sphincter because of post-complications. Thirty-five patients were socially continent, of which 16 patients were totally dry, leading to the overall social continent rate as 76.1%(35/46). There was a significant reduction in pad usage to 1.2±0.6 diapers per day ( P<0.001). The impact of incontinence on the QOL measured by the VAS dropped to 2.6±1.9 ( P<0.001). The complication rate was 32.6%(15/46), including infections ( n=4), erosions ( n=5), mechanical failure ( n=3), dysurie ( n=2) and urethral atrophy ( n=1). There were no significant differences in social continent rate between patients with different etiologies[75.0%(18/24)vs. 66.7%(6/9) vs. 84.6%(11/13)], perioperative complications [37.5%(9/24)vs. 33.3%(3/9) vs. 23.1%(3/13)] and device re-intervention rate[37.5%(9/24) vs. 33.3%(3/9)vs. 15.4%(2/13)]. There were no statistically significant differences in postoperative complete dry rate [32%(8/25)vs. 40%(8/20), P=0.76] and postoperative device failure free rate [60%(15/25)vs. 80%(16/20), P=0.20] between trans-perineal group and trans-scrotal group. There was no statistically significant difference in postoperative social continent rate between 4.5cm cuff and 4.0 cuff[75%(12/16) vs. 65.5%(19/29), P=0.74]. Conclusions:Artificial urethral sphincter implantation is an effective treatment for stress urinary incontinence due to intrinsic sphincter deficiency. There was no difference in the continent rate and complication rate between patients of different etiologies, different surgical approaches and cuff size selection.
