Objective To evaluate the efficacy and safety of Mirabegron combined with transcutaneous tibial nerve stimulation (TTNS) in the treatment of drug-refractory overactive bladder (OAB), so as to alleviate patients'symptoms, improve their quality of life with optimized treatment plan, and provide reference for clinical practice. Methods A retrospective analysis was conducted on 56 patients with drug-refractory OAB treated at the Department of Urology of Gansu Provincial Hospital during Jan.2023 and Dec.2024. Based on the treatment methods, the patients were divided into two groups:the TTNS group and the combined treatment group, with 28 patients in either group. The daytime urination frequency, nocturia frequency, urgency episodes, urinary incontinence, functional bladder capacity (FBC), OAB symptom scores (OABSS), and incontinence quality of life questionnaire (I-QoL) scores were collected before and after treatment. The therapeutic efficacy was evaluated using the Nimodipine method. Results After 12 weeks of treatment, the 24-hour urination indicators in both groups including daytime urination frequency, nocturia frequency, urgency episodes and FBC, as well as OABSS and I-QoL scores, showed a significant improvement compared to baseline (P<0.001). The combined treatment group exhibited fewer urgency episodes than the TTNS group [ (1.07±0.66) times/24 h vs. (1.64±0.62) times/24 h, P<0.05]. However, no statistically significant differences were observed between the two groups in other urinary parameters (P>0.05). The total effective rate in the combined treatment group was 96.43%, which was significantly higher than that in the TTNS group (82.14%, P<0.05). During treatment, one patient (3.57%) in the TTNS group experienced mild skin allergy, which recovered following symptomatic management. Conclusion The combination of TTNS and Mirabegron in drug-refractory OAB not only alleviates clinical symptoms and improves quality of life, but also shows superior efficacy in reducing urgency episodes. This approach is a safe and effective treatment option.

Interstitial cystitis/bladder pain syndrome (IC/BPS) is a refractory condition characterized by chronic inflammation of the bladder wall, disruption of the urothelial barrier, and neural sensitization. Current therapies, such as oral pentosan polysulfate sodium (PPS) or intravesical hyaluronic acid instillations, offer limited efficacy due to transient effects and an inability to reverse tissue fibrosis. Platelet-rich plasma (PRP), a regenerative medicine approach, has demonstrated significant therapeutic potential in urological disorders through the synergistic actions of its multiple growth factors. This review summarizes the latest advances in PRP therapy for IC/BPS, revealing that the underlying mechanisms primarily involve the release of diverse growth factors, suppression of inflammatory responses, restoration of the urothelial barrier, and modulation of nerve axonal regeneration. Clinically, PRP therapy significantly alleviates symptoms including pelvic/bladder pain, urinary frequency, nocturia episodes, and improves patients'quality of life. Furthermore, it offers advantages such as convenient administration, a favorable safety profile, and strong feasibility, presenting new therapeutic methods and options for the clinical treatment of IC/BPS.

Fast-track surgery (FTS) protocols was introduced to reduce surgical stress and facilitate postoperative recovery.It has been more than 20 years since it had been proposed and it was successfully used in many special subjects such as orthopedic,upper gastrointestinal,gynecological,thoracic,vascular,endocrine et al,but the implication in radical cystectomy was insufficient.The propose of this article was to summarize the implication of FTS in radical cystectomy and to promote the development of the protocol in radical cystectomy.

Polyethersulfone (PES) hollow fibers were fabricated by dry-wet spinning method for hemodialysis application. The effects of additives polyethylene glycols (PEG) in the dope solution and of fiber thickness and inner diameter fiber on the membrane mechanical characters were investigated. The dialysis tests were conducted by using a simulated solution prepared by dissolving bovine serum albumin (BSA), lysozyme and urea in de-ionized water to test the effects of membrane characters and operating conditions on dialysis efficiency. The results indicated that the reduction of PEG concentration from 27.6 wt% to 24.1 wt% in the dope solution improved the clearance of toxins, but slightly decreased the mechanical characters. The reduction of fiber thickness or fiber inner diameter was found to improve the clearance of toxins by removing 64.2% of lysozyme and 89.4% of urea (membrane area 0.2 m2), whilst BSA retention was found being maintained above 98%. The dialysis efficiency was also noted to increase with the increase in the flow rate of either the simulated or the dialysate solution, or increasing the membrane area. Moreover, The result of a comparison on the clearance of toxins between commercial F60S and PES dialyzers indicated higher dialysis efficiency per area of the fabricated PES membrane.

[Objective] To observe effective method of treating chronic prostatitits.[Method] Randomly divide 96 cases into 2 groups:the treatment group was treated with herbs by enema and oral antibiotics.The control group was treated with oral antibiotics.[Result] For both groups,clinical symptoms and signs disappeared much differently(P

Objective To describe the clinical curative effects of surgical treatment of female stress urinary incontinence by tension-free vaginal tap.Methods Surgical treatment of 17 women suffering from stress urinary incontinence whose average course are11years by tension-free vaginal tap.Then,observe the complications and how symptome improved after operation.In this 17 cases,one had a failure experience of bladder neck ventrofixation,another had an operation of pelvic cavity in the past.Results All operations were successed,the mean operative time was about 30 minutes,the mean amount of bleeding was 40ml.No case had the complication of bladder perforated and dysuria after operation.The urinary incontinence symptomes were disappered within 5 days after operation.During a follow up of 3～12 months,no SUI recurred.Conclusions Our result demonstrates that TVT has the virtues of small trauma、simplely manipulate and less complications.Patients recover well and have a high rate of curing.It can also be use in such patients who had operations of pelvic cavity and failure operation for SUI in the past.
