There are no reports on the application of perirenal fat covering technique in lingual mucosal graft ureteroplasty（LMGU），and its safety and effectiveness need to be observed. This study retrospectively analyzed clinical data of 7 patients who underwent lingual mucosa ureteroplasty with intraoperative perirenal fat covering technique. The median stricture length was 5.5（range 4.0 to 6.0）cm，operative duration was 170（range 120 to 230）min，estimated blood loss was 92（range 15 to 110）ml. No conversions to open surgery occurred. During a median follow-up of 46（range 8 to 86）months，all procedures achieved clinical success. The application of perirenal fat covering technique in LMGU is safe and effective.

Objective:To evaluate the long-term effectiveness of lingual mucosal graft ureteroplasty (LMGU) for managing long-segment (≥5 cm) ureteral strictures in a multi-institutional cohort of patients.Methods:A multi-center retrospective case series study was conducted on clinical data from 42 patients undergoing LMGU for long-segment ureteral strictures (≥5 cm) across five institutions between February 2017 and June 2024. The cohort comprised 31 males and 11 females, with an age of (43.4±12.0) years (range: 15 to 64 years) and a body mass index of (24.6±2.6) kg/m2 (range: 16.0 to 30.0 kg/m2). Strictures involved the left ureter in 24 cases and right ureter in 18 cases, demonstrating a stricture length of (6.4±1.5) cm (range: 5.0 to 11.5 cm). Surgical interventions included either onlay ureteroplasty or augmented anastomotic ureteroplasty, selected according to intraoperative findings. Intraoperative parameters, postoperative complications, and follow-up outcomes were analyzed.Results:Laparoscopic surgery was performed in 22 cases and robot-assisted surgery in 20 cases. Among the 42 patients, 22 underwent onlay ureteroplasty while 20 received augmented anastomotic ureteroplasty. The graft length was (5.9±1.8) cm (range: 3.0 to 12.0 cm), operative time (191.5±55.6) minutes (range: 105.0 to 350.0 minutes), and intraoperative estimated blood loss (86.7±73.6) ml (range: 10.0 to 400.0 ml). All procedures were successfully completed without conversion to open surgery. The postoperative hospital stay was (7.6±2.0) days (range: 4.0 to 15.0 days), with double-J stent removal at 6 to 8 weeks postoperatively. During a follow-up of (49.1±25.0) months (range: 12.0 to 99.0 months), no stricture recurrence was observed in any patient.Conclusion:LMGU is a safe, feasible, and effective long-term technique for managing long-segment (≥5 cm) ureteral strictures.

Objective To investigate treatment of meditation training for elderly patients with cogni-tive disorder recovering from operation for valvular heart disease( VHD) . Method 67 elderly patients who were up to the inclusion criteria were divided into experiment group( n=34)and control group( n=33),by dropping coins according to the admission time.Both of the two groups accepted regular health education and mental nursing.Besides,the experiment group accepted meditation training 5 times a week. Montreal Cogni-tive Assessment (MoCA) was used to evaluate cognitive function before and after the treatment. Results ( 1) Ridit analysis showed the intervention effect of the experimental group was better than that of the control group( R=2.12, t=-2.48, u=0.02),and the difference was statistically significant(P<0,05).The total effec-tive rate of experiment group is 90.32%,while the rate of control group is 62.89%. (2)The score of MoCA for the experiment group(25.79±1.23)was higher than that of the control group(23.85±1.82)after 6 weeks intervention,and the difference was statistically significant( t=5.14,P<0.01).(3) The score of MoCA of the experiment group before the intervention (23.91±2.22)was lower than after 6 weeks intervention(25.79±1. 23),and the difference was statistically significant( t=-4.30,P<0.01).Conclusion Meditation training can effectively improve cognitive function of elderly patients recovering from operation for VHD.
