Objective:To investigate the characteristics and clinical effects of laparoscopic pneumovesical Cohen and laparoscopic Lich-Gregoir ureteral replantations for the treatment of primary obstructive megaloureter (POM) in children.Methods:A randomized controlled study was conducted.The clinical data of 51 children with unilateral POM admitted to the First Affiliated Hospital of Zhengzhou University from October 2018 to October 2023 were collected.Random number table method was used in the selection of surgical methods.They were divided into the laparoscopic pneumovesical Cohen ureteral replantation group (group A, 22 cases) and the laparoscopic Lich-Gregoir ureteral replantation group (group B, 29 cases) according to the surgical method.The anterior-posterior diameter(APD), maximum ureteral diameter and differential renal function parameters on the affected side were measured by color Doppler ultrasound of the urinary system, and compared between and within the two groups before and after surgery.The operation time, blood loss and postoperative intubation time were compared between the two groups.The incidence of postoperative complications such as reflux, bladder spasm, urinary retention and urinary tract infection was recorded.The independent and paired sample t-tests were used for statistical analysis. Results:The operation time and hematuria duration of group B [(125.7±14.2) min, (1.5±0.6) d] were significantly shorter than those of group A [(142.6±14.7) min, (2.8±0.7) d] (all P<0.05). The APD, maximum ureteral diameter, and differential renal function on the affected side of group A were (21.7±7.9) mm, (11.6±3.2) mm, and (28.2±4.9)% before surgery, and (10.3±4.5) mm, (6.0±2.0) mm and (43.8±4.4)% after surgery, respectively.The APD, maximum ureteral diameter, and differential renal function on the affected side of group B were (21.1±5.6) mm, (11.3±4.6) mm, and (30.2±5.5)% before surgery, and (10.2±4.5) mm, (6.6±2.0) mm, and (42.4±5.2)% after surgery, respectively.There was no statistically significant difference in the values of APD, maximum ureteral diameter, and differential renal function before and after surgery between the two groups of children (all P>0.05). However, there were statistically significant differences in the values of APD, maximum ureteral diameter, and differential renal function before and after surgery between the same group of children (all P<0.01). No significant difference was found in intraoperative blood loss, postoperative intubation time, and postoperative complications between the two groups (all P>0.05). Conclusions:Both surgical methods are effective in the treatment of POM in children.Laparoscopic Lich-Gregoir ureteral replantation has advantages of less operation time compared with laparoscopic pneumovesical Cohen ureteral replantation.

OBJECTIVE: To observe the effects of Tiaoshu Anshen (regulating the hinge and calming the mind) acupuncture on sleep quality and serum levels of 5-hydroxytryptamine (5-HT) and dopamine (DA) in patients with chronic insomnia. METHODS: A total of 58 patients with chronic insomnia were randomly divided into an acupuncture group and a medication group, 29 cases in each group. Tiaoshu Anshen acupuncture was applied at Baihui (GV20) and bilateral Shenmen (HT7), Sanyinjiao (SP6), Benshen (GB13) in the acupuncture group, once a day, 1-day interval was taken after 6 consecutive days of treatment. Estazolam tablet was given orally before bed in the medication group, 1 mg each time. The 4-week treatment was required in both groups. Before and after treatment, the sleep quality was assessed by Pittsburgh sleep quality index (PSQI) and polysomnography (PSG), the serum levels of 5-HT and DA were detected by ELISA. RESULTS: After treatment, the item scores and total scores of PSQI were decreased compared with those before treatment in the two groups (P<0.05); in the acupuncture group, the scores of sleep quality, sleep latency, sleep time, sleep efficiency, sleep disorders and total score of PSQI were lower than those in the medication group (P<0.05). After treatment, the total sleep time (TST) was prolonged (P<0.05), the sleep latency (SL) and wake after sleep onset (WASO) were shortened (P<0.05), the sleep efficiency (SE%), percentage of non-rapid eye movement stage 3 (N3%), percentage of rapid eye movement stage (REM%) and serum levels of 5-HT were increased (P<0.05) compared with those before treatment; the percentage of non-rapid eye movement stage 1 (N1%), percentage of non-rapid eye movement stage 2 (N2%) and serum levels of DA were decreased (P<0.05) compared with those before treatment in the two groups. After treatment, in the acupuncture group, TST was longer, while SL and WASO were shorter than those in the medication group (P<0.05), SE%, N3%, REM% and serum level of 5-HT were higher, while N1%, N2% and serum level of DA were lower than those in the medication group (P<0.05). CONCLUSION Tiaoshu Anshen acupuncture may improve the sleep quality by regulating the serum neurotransmitter levels i.e. 5-HT and DA in patients with chronic insomnia.
