Résumé
ABSTRACT Objective: To evaluate objective treatment efficacy and safety, and subjective patient-reported outcomes in patients with complex ureteral strictures (US) undergoing minimally invasive lingual mucosal graft ureteroplasty (LMGU). Materials and Methods: We prospectively enrolled patients underwent robotic or laparoscopic LMGU between May 2020 and July 2022. Clinical success was defined as symptom-free and no radiographic evidence of re-obstruction. Patient-reported outcomes, including health-related quality of life (HRQoL), mental health status and oral health-related quality of life (OHRQoL), were longitudinally evaluated before surgery, 6 and 12 months postoperatively. Results: Overall, 41 consecutive patients were included. All procedures were performed successfully with 32 patients in robotic approach and 9 in laparoscopic. Forty (97.56%) patients achieved clinical success during the median follow-up of 29 (range 15-41) months. Although patients with complex US experienced poor baseline HRQoL, there was a remarkable improvement following LMGU. Specifically, the 6-month and 12-month postoperative scores were significantly improved compared to the baseline (p < 0.05) in most domains. Twenty-eight (68.3%) and 31 (75.6%) patients had anxiety and depression symptoms before surgery, respectively. However, no significant decrease in the incidence of these symptoms was observed postoperatively. Moreover, there was no significant deterioration of OHRQoL at 6 months and 12 months postoperatively when compared to the baseline. Conclusions: LMGU is a safe and efficient procedure for complex ureteral reconstruction that significantly improves patient-reported HRQoL without compromising OHRQoL. Assessing patients' quality of life enables us to monitor postoperative recovery and progress, which should be considered as one of the criteria for surgical success.

ABSTRACT Purpose Horseshoe kidney (HSK) is the most common renal fusion anomaly, occurring in 0.25% of the population (1). It presents technical obstacles to pyeloplasty for ureteropelvic junction obstruction (UPJO) despite robotic assistance (2, 3). KangDuo-Surgical-Robot-01 (KD-SR-01), an emerging robotic platform in China, has yielded satisfactory outcomes in pyeloplasty (4, 5). We first describe our modified technique of robotic bilateral pyeloplasty for UPJO in HSK using KD-SR-01 system in the Lithotomy Trendelenburg position. Materials and Methods A 36-year-old man with HSK and bilateral UPJO suffered right flank pain due to renal calculi (Figure-1). Repeated double-J stent insertion and ureteroscopy lithotripsy did not relieve his symptoms. A robot-assisted modified bilateral dismembered V-shaped flap pyeloplasty was performed using KD-SR-01 system in the Lithotomy Trendelenburg position. Results Total operative time was 298 minutes with 50 ml estimated blood loss. There was no conversion to laparoscopic or open surgery. A follow-up of 14 months showed relieving symptoms and stable renal function. Cine magnetic resonance urography and computed tomography urography revealed improved hydronephrosis and good drainage. No intraoperative or postoperative complications occurred. Conclusions It is technically feasible to perform a KD-SR-01-assisted modified bilateral dismembered V-shaped flap pyeloplasty in the Lithotomy Trendelenburg position for HSK. This procedure achieves managing UPJO on both sides without redocking the system and provides a wider operative field. In addition, it may be associated with better ergonomics, better cosmetic outcomes, and less possibility of postoperative bowel adhesion. However, further investigation is still warranted to confirm its safety, efficacy, and advantages over traditional procedures.

@#Accurate positioning of brackets is a necessary condition for ideal orthodontic treatment. Traditional bracket bonding technology has certain limitations, such as long operation time and poor accuracy. Indirect bonding technology is a method that bonding brackets on the model through intraoral impression or scanning, and then the brackets are accurately bonded to the tooth crowns using a transfer tray. In this article, the progression of transfer trays and adhesive agents, the application of digital technology in indirect bonding technology, indirect bonding for invisible appliances, and the prospect of this technology are reviewed. The literature review results show that indirect bonding technology can locate the bracket accurately, the operation is simple, the patient’s experience is comfortable, and the clinical efficiency can be significantly improved, the photocurable adhesive is an ideal adhesive for indirect bonding technology. With the development of digital technology, indirect bonding technology will be able to locate the brackets with increasing accuracy, thus achieving the "digital precision movement" of the teeth. The bonding technology of invisible appliance accessories is essentially a type of indirect bonding technology, It requires indirect bonding technology and digital technology to highly fit the needs of computer design accessories for the visual tooth movement and the use of indirect bonding technology to accurately bond accessories, ultimately achieving the desired tooth movement. Indirect bonding technology will play an increasingly important role with the development of digital technology and invisible correction technology.
