ABSTRACT
OBJECTIVE@#To summarize the experiences and outcomes of 108 robot-assisted laparoscopic upper urinary tract reconstruction surgeries conducted by a single surgeon.@*METHODS@#We consecutively and retrospectively reviewed 108 patients who underwent robot-assisted laparoscopic upper urinary tract reconstruction surgeries by a single surgeon from November 2018 to January 2020. The patient demographics, perioperative variables, postoperative complications and follow-up data were recorded. Fifty-three modified dismembered pyeloplasties (MDP), 11 spiral flap pyeloplasties (SFP), 11 ure-teroureterostomies (UUT), 4 lingual mucosal onlay graft ureteroplasties (LMU), 5 appendiceal onlay flap ureteroplasties (AU), 11 ureteral reimplantations (UR), 6 Boari flap-Psoas hitch surgeries (BPS) and 7 ileal ureter replacements (IUR) were enrolled finally. The success was defined as the improvement in subjective pain levels, and the improvement in the degree of hydronephrosis at ultrasound.@*RESULTS@#All the surgeries were successfully completed without open or laparoscopic conversion. The median operative time was 141 min (range: 74-368 min), median blood loss was 20 mL (range: 10-350 mL) and median hospital stay was 4 d (range: 3-19 d) in MDP group, with the success rate of 94.3%. The median operative time was 159 min (range: 110-222 min), median blood loss was 50 mL (range: 20-150 mL) and median hospital stay was 5 d (range: 3-8 d) in SFP group, with the success rate of 100%. The median operative time was 126 min (range: 76-160 d), median blood loss was 20 mL (range: 10-50 mL) and median hospital stay was 5 d (range: 4-9 d) in UUT group, with the success rate of 100%. The median operative time was 204 min (range: 154-250 min), median blood loss was 30 mL (range: 10-100 mL) and median hospital stay was 6 d (range: 4-7 d) in LMU group, with the success rate of 100%. The median operative time was 164 min (range: 135-211 min), median blood loss was 75 mL (range: 50-200 mL) and median hospital stay was 8.5 d (range: 6-12 d) in AU group, with the success rate of 100%. The median operative time was 149 min (range: 100-218 min), median blood loss was 20 mL (range: 10-50 mL) and median hospital stay was 7 d (range: 5-10 d) in UR group, with the success rate of 90.9%. The median operative time was 166 min (range: 137-205 min), median blood loss was 45 mL (range: 20-100 mL) and median hospital stay was 5 d (range: 4-41 d) in BPS group, with the success rate of 83.3%. The median operative time was 270 min (range: 227-335 min), median blood loss was 100 mL (range: 10-100 mL) and median hospital stay was 7 d (range: 5-26 d) in IUR group, with the success rate of 85.7%.@*CONCLUSIONS@#The surgeon performed and modified numerous complicated upper urinary tract reconstruction surgeries by the robotic platform, which facilitated the development of the standardized upper urinary tract reconstruction surgical technique.

?AlM: To investigate the clinical characteristics and influencing factors of chronic renal failure ( CRF) patients with dry eye, and to provide clinical reference.?METHODS:Sixty-one cases (122 eyes) of patients with CRF ( CRF group ) and 61 cases ( 122 eyes ) of healthy persons ( control group) were carried out on Schirmer ▏test ( S▏t ) , break-up time of tear film ( BUT ) , corneal fluorescein staining ( FL) , test results of two groups were compared and related factors of dry eye in CRF patients were analyzed.?RESULTS: The results of S▏t and BUT in CRF group were lower than that in the control group (P<0. 05). The proportion of tear secretion reduce in CRF group ( S▏t<10mm/5min) was 49. 2% ( 60/122 ), which was higher than that in the control group ( 10. 0%, 12/122 ), the difference was statistically significant ( X2 = 45. 39, P <0. 05). The percentage of instability of tear film in CRF group (BUT≤10s) was 75. 4% (92/122), which was significantly higher than that in the control group (27. 0%, 33/122) (X2=57. 1, P<0. 05). The positive rate of corneal FL was 37. 7% (46/122), which was higher than that of the control group (10. 7%, 13/122), there was a statistically significant difference (X2= 24. 34, P<0. 05).?CONCLUSlON:CRF patients with a decrease in tear film stability and tear secretion are susceptible population to dry eye, clinically should be paid attention to the treatment.
ABSTRACT
<p><b>OBJECTIVE</b>To evaluate the effect of local X-irradiation on spinal cord injury by using physiology, kinology, electrophysiology and histology method.</p><p><b>METHODS</b>46 female Sprague-Dawley rats were subjected to spinal cord injury by weight dropping on T(11-12). All animals were divided into 3 groups randomly. One of the animal groups was irradiated with 10 Gy at the lesion site; another was irradiated with 20 Gy, the other without irradiation is regarded as sham-group. The animals were euthanized at different time points at 4 and 12 weeks after irradiation. Spinal cord callus was assessed by using physiology, kinology, and electrophysiology and histology method.</p><p><b>RESULTS</b>In all the groups, the NF at 14 weeks were found higher than that of 6 weeks. Both 10 Gy irradiated and 20 Gy irradiated groups were higher than those of group at each time point (P < 0.05). The MBP decreased at 14 weeks in irradiated groups (P < 0.05), but increased at 14 weeks in sham-group (P < 0.05), the MBP of irradiated groups was lower than that sham-group at 14 weeks (P < 0.05). The GFAP and Nogo-A at 14 weeks were higher than that in 6 weeks in all the groups (P < 0.05), and there was no statistical significance with physiology, kinology, electrophysiology test in all groups.</p><p><b>CONCLUSION</b>A self-repair mechanism exists after SCI, which will last at least 14 weeks. Local irradiation promotes the regeneration of spinal cord system after injury to some extent.</p>
