<b><i>Objectives:</i></b> This study aims to assess the safety and efficacy of INNOVEX<sup>TM</sup> ureteral dilation balloon catheter to promote the likelihood of passing the ureter to complete primary ureteroscopy (URS). <b><i>Methods:</i></b> This was a prospective case series of patients during URS between August 2018 and January 2020 at the Pudong New District People’s Hospital. A 12-Fr INNOVEX<sup>TM</sup> ureteral dilation balloon catheter was used to dilate the ureter when a 5° Wolf 6.0/7.5-Fr ureteroscope encounters an unpredictable hindrance to retrograde access for ureteral stones. Patients with documented ureteral strictures, radiation therapy, or urothelial cancer were excluded from the analysis. The primary outcomes were to characterize the use, safety, and efficacy of ureteral dilation balloon catheter to promote stone treatment during URS. <b><i>Results:</i></b> Eight hundred and sixty-two patients underwent primary URS of ureteral stones over the study period. The use of a ureteral dilation balloon catheter to promote ureteral access was performed in 65 (7.54%) cases and effectively allowed completion of the procedure in 58 (89.23%) cases. No ureteral perforation and access loss occurred during the operation. Seven patients required ureteral stent placement for passive ureteral dilation, with definitive stone treatment later. Postoperative radiographic follow-up was available for 63 (96.92%) cases, and no ureteral stenosis was observed after balloon dilation. <b><i>Conclusion:</i></b> The use of a new ureteral dilation balloon catheter before endoscopic treatment of ureteral stones was associated with a high success rate and few complications. The convenient use method under direct vision at the whole process may increase the willingness of doctors to use it. In addition, it may reduce the need for secondary procedures for patients undergoing URS to manage ureteral stones.

Abstract Background Clinical data show that due to the limited effects of lifestyle regulation and unsatisfactory drug adherence, only half of the hypertensive population have their blood pressure (BP) under control. In recent years, catheter-based renal denervation (RDN) has been used as a novel approach for treating uncontrolled hypertension. The safety and efficacy of catheter-based RDN have been confirmed by a number of studies and trials in which the participants were all non-Chinese and RDN was conducted via radiofrequency or ultrasound. Methods/design This study is a prospective multicenter randomized sham-controlled trial that aims to investigate the safety and efficacy of cryoablation RDN (cryo-RDN) using a novel dedicated cryoablation balloon catheter (Cryofocus, China). A total of 200 Chinese patients who have uncontrolled hypertension despite standard medical treatment will be enrolled. With drug standardization, eligible participants will be randomized in a 1:1 ratio to undergo cryo-RDN treatment or renal angiography alone as a sham treatment. The primary endpoint is defined as the change in 24-h ambulatory systolic blood pressure from baseline to 6 months. Office BP and other 24-h ambulatory BP are included as secondary endpoints. Safety endpoints primarily include any adverse effects. Discussion This study was designed to verify the safety and efficacy of cryo-RDN with Cryofocus balloon catheters in uncontrolled hypertensive patients on polypharmacy. The aim is to provide a new way to improve the control of hypertension in China as a complement to drug therapy. Trial registration ChiCTR, ChiCTR1800017707. Registered on 10 August 2018.

Abstract Purpose To study the safety and efficacy of pterygium extended removal followed by extended conjunctival transplant for recurrent pterygia. Methods Thirty-three eyes of 33 subjects with recurrent pterygia were enrolled in this prospective case series study. Pterygium extended removal followed by extended conjunctival transplantation was done for all subjects. One surgeon (WA) performed all surgeries. All subjects completed follow-up for at least 12 months and were evaluated for recurrence and complications. Results The mean age of the participants was 41.2 ± 10.3 years (range 22–60), 7 females (21.2%). The mean duration of follow-up was 25.64 ± 9.24 months (range 12–43). Corrected distance visual acuity (decimal notation) improved from 0.69 ± 0.22 (range 0.2–1.0) at presentation to a 1-year postoperative value of 0.83 ± 0.2 (range 0.3–1.0). No recurrence was reported in all subjects throughout the follow-up period. Transient graft swelling was recorded in 14 cases (42.4%) and resolved in all cases by the first week. All patients developed variable degrees of transient postoperative diplopia that resolved completely by the first 6 weeks. Donor site granuloma developed in 4 cases (12.1%). Spontaneous resolution was observed in 3 cases, while in one case, surgical excision was performed 2 months after the procedure. Conclusions In this study of eyes with recurrent pterygia, pterygium extended removal followed by extended conjunctival transplant was found safe and effective with no recurrence and minimal postoperative complications.

OBJECTIVE: To evaluate safety and efficacy of additional palatal implants for snoring treatment. STUDY DESIGN AND SETTING: A prospective case series at two clinical sites in an office setting. Patients who did not have an acceptable reduction in snoring intensity after an initial 3 implant procedure received additional implants. Bed partners rated snoring intensity on a 10 cm visual analog scale (VAS) at baseline and 90 days postprocedure. RESULTS: Snoring intensity VAS decreased significantly from 6.4 ± 2.3 to 4.6 ± 2.9 ( P < 0.01) for patients who received an additional fourth implant, and to 4.1 ± 2.8 after the 5th implant ( P<0.01). Epworth sleepiness scale scores also decreased significantly for patients who received additional fourth or fifth implants. There were no adverse events. CONCLUSIONS: Additional palatal implants for snoring treatment were safe and effective in this case series. SIGNIFICANCE: Additional implants may offer relief for snorers not responding to the initial 3 implant procedure.

AbstractThe aim of this study was to assess feasibility and safety of office-based transnasal balloon dilation of neopharyngeal and proximal esophageal strictures in patients with a history of head and neck carcinoma. The secondary objective was to explore its effectiveness. This prospective case series included patients previously treated for head and neck carcinoma with neopharyngeal or proximal esophageal strictures who underwent transnasal balloon dilation under topical anesthesia. The target dilation diameter was 15 mm; if necessary dilation procedures were repeated every 2–4 weeks until this target was reached. Completion rates, adverse events, and patient experiences measured by VAS scores (0 = no complaints – 10 = unbearable complaints), dysphagia scores based on food consistency (0 = no dysphagia – 5 = unable to swallow liquids/saliva), and self-reported changes in swallowing symptoms were recorded. Follow-up was 2 months. Twenty-six procedures were performed in 12 patients, with a completion rate of 92%. One minor complication occurred, i.e. an infection of the dilation site. Tolerance of the procedure was good (median VAS = 2). The dysphagia score improved after a mean of 2.2 procedures per patient, however not significantly. Eight patients reported improvement in dysphagia, of whom 3 had recurrence of dysphagia within 1 month post-treatment. Office-based transnasal balloon dilation is a feasible and safe in-office procedure which is well-tolerated by patients. The dilations can improve dysphagia, although effects might be transient.

AbstractBackground:Eustachian tube dysfunction is a disorder for which there are limited medical and surgical treatments. Recently, eustachian tube balloon dilation has been proposed as a potential solution.Method:A systematic literature review was performed. Abstracts were selected for relevance, and pooled data analysis and qualitative analysis was conducted.Results:Nine prospective studies, describing 713 eustachian tube balloon dilations in 474 patients (aged 18–86 years), were identified. Follow-up duration ranged from 1.5 to 18 months. Ability to perform a Valsalva manoeuvre improved from 20 to 177 out of 245 ears following eustachian tube balloon dilation and, where data were reported in terms of patient numbers, from 15 to 189 out of 210 patients. Tympanograms were classified as type A in 7 out of 141 ears pre-operatively and in 86 out of 141 ears post-operatively.Conclusion:Prospective case series can confirm the safety of eustachian tube balloon dilation. As a potential solution for chronic eustachian tube dysfunction, further investigations are warranted to establish a higher level of evidence of efficacy.
