Background: To evaluate the efficacy of submucosal injection of triamcinolone acetonide for the treatment of type II/III interstitial cystitis/bladder pain syndrome. Methods: A retrospective analysis of the clinical data of type II/III interstitial cystitis/bladder pain syndrome patients treated in our department from April 2016 to August 2018 was conducted, and changes in International Prostate Symptom Scores and the Pelvic Pain and Urgency/Frequency symptom scale after surgery were evaluated to explore factors that may affect patient outcomes. Results: A total of 27 female patients and 8 male patients were enrolled, with type II patients accounting for 62.9% of the sample, and the median follow-up duration was 31 months (range: 12-40 months). Twenty-two patients (74.3%) had significantly improved questionnaire scores at 4 weeks postoperatively. Treatment efficacy was sustained for at least 1 year in 15 patients, and persistent effectiveness was noted in 10 (28.6%) patients. Patients with an advanced age (p=0.015), high pain scores (p=0.040), and higher International Prostate Symptom Scores (p=0.037) and Pelvic Pain and Urgency/Frequency symptom scale scores (p=0.020) were more likely to benefit from submucosal injection of triamcinolone acetonide. Gender, disease duration, and the presence of Hunner’s lesions had no predictive value for treatment outcomes. Conclusion: Submucosal injection of triamcinolone acetonide can improve the clinical symptoms and quality of life in both men and women with type II/III interstitial cystitis/bladder pain syndrome. Patients with an advanced age and more severe interstitial cystitis/bladder pain syndrome related symptoms may benefit more from triamcinolone acetonide injection.

Background We designed a new surgical procedure to treat benign prostatic hyperplasia(BPH). In order to verify its effectiveness and safety, we constructed this randomized controlled trial to compare the efficacy of our innovative enucleation technique- photoselective sharp enucleation of the prostate (PSEP), with a front-firing 532-nm laser and the traditional technique-photoselective vaporization of the prostate (PVP) in the treatment of BPH. Methods A total of 154 consecutive patients diagnosed with bladder outlet obstruction secondary to BPH in our center from June 2018 to April 2019 were randomly divided into the PSEP group (n = 77) and the PVP group (n = 77) and were treated surgically with either PSEP or PVP. All patients were assessed preoperatively and followed up at 1, 6, and 12 months postoperatively. The international prostate symptom score,quality-of-life score, postvoid residual urine volume, maximum urine flow rate, prostate volume, prostate-specific antigen, and adverse events were compared. Results The lower urinary tract symptoms in both groups were significantly improved compared with the baseline at 1, 6, and 12 months postoperatively. The PSEP and PVP groups had an equivalent International Prostate Symptom Score, quality-of-life score, postvoid residual urine volume, maximum urine flow rate, prostate-specific antigen at each follow-up (P > 0.05). The median operative time in the PSEP group was significantly shorter than that in the PVP group (35 min vs. 47 min, P < 0.001). At 6 and 12 months after surgery, the median PV in the PSEP group was smaller than that in the PVP group (P < 0.05). Complication rates were comparable between the groups. Conclusion Both PSEP and PVP can achieve good efficacy and safety in the treatment of BPH. PSEP can remove more tissue than PVP and is associated with higher efficiency. In addition, PSEP eliminates the problem of lack of tissue samples associated with PVP. Trial registration Chinese Clinical Trial Registry, identifie:ChiCTR1800015867, date:25/04/2018.
